Field of the Invention
[001] The present invention relates to an article of clothing to pull (pants type) and a method of production thereof. Fundamentals of the Invention
[002] Like a conventional pull diaper, a pull diaper is known comprising an outer cover adapted to be worn around the front and back side of a user, and a crotch part adapted for use along the groin of the user, which is arranged between the front side and the rear side of the outer cover, where an absorbent body is arranged on the groin part (for example, see Patent Literature 1 and 2).
[003] The outer covering has a two-layer structure of an inner layer material and an outer layer material laminated to almost all of its surfaces, and a sheet to which the inner layer material and the outer layer material are attached. each other through an interleaved elastic member is used to constitute the outer cover. This sheet is divided in two in the width direction, and an absorbent body is arranged so as to connect the parts of sheet divided in parallel, the outer edge parts of the outer layer materials constituting the sheets are respectively folded, and both parts edge of the absorbent body are fixed by folded parts. Subsequently, the absorbent body is folded in the vicinity of the central part and the sheets are superimposed so that the inner layer material between, and the sheets which are superimposed in order to intercalate the absorbent body between them are joined at predetermined intervals in the direction side. After that, the central part of the joined part is cut in the lateral direction of the leaves and the cut parts are separated. In this way, a pull-out diaper comprising an outer cover formed by the joining sheets, and an absorbent body attached to that outer cover is completed (for example, see patent literature 1).
[004] Another structure described comprises an integral outer covering sheet that covers from a front body to a rear body, strip-like laminated materials extending in the lateral direction, which are varied in a longitudinally skewed arrangement on the external surface the outer cover sheet; and an elastic member under the waist that also acts as a collected elastic member, which is interspersed in an edge part on the waist side of the overlapping parts of the strip-like laminate substrates and the outer cover sheet and fixed by a thermal melting adhesive or similar (for example, see patent literature 3). Since each edge portion on the groin side in the CD direction (the lateral direction at right angles to the line flow direction) of the strip-like laminate materials is arranged to cover another strip-like laminate substrate, the outer cover sheet as a whole it has a two-layer structure comprising at least one outer cover sheet and strip-like laminate materials (the outer cover sheet has a three-layer structure on the overlapping part of the strip-like laminate materials). A production method comprises the continuous intercalation of the elongated elastic member between the outer cover sheet and the strip-like laminate substrates, while, at the same time, fixing the elastic member to the waist side edge parts of the strip-like substrates using a thermal melting adhesive. Therefore, it is necessary to arrange the respective strip-like laminate materials in a skewed arrangement so that the respective strip-like laminate substrates are partially overlapping, and thus the position accuracy of the strip-like laminate materials with respect to the elongated elastic elements is important.

[008] Pulling diaper users want the comfort of wearing an underwear and want further improvement in flexibility and air permeability as conventional pull diapers have an outer cover of a two-layer structure whose layer material inner and outer layer material are laminated over almost the entire surface. Specifically, this is most likely the case in which an engraved sheet such as spabond fabrics are used. In addition, a structure in which the strip-like laminated materials to serve as waist adornment elements are arranged in the longitudinal direction has a two-layer structure or a three-layer structure, so that further improvement of air permeability is desirable.
[009] The present invention relates to an article of pull clothing that solves the problem of wetting during use by softening an area around the waist of an outer cover of a pulling diaper and improving the air permeability. In addition, the present invention relates to a method of producing a garment for pulling in which ribbon-like laminated materials (strip-like laminated materials), which are formed by cutting a sheet such as a non-woven fabric into small widths , are stably arranged at predetermined intervals with great precision in the case where tape-like laminated materials are fixed. Solution to the Problem
[010] The present invention resides in an article of clothing for pulling comprising a front part that is adapted to be worn around the front side of a user, a groin part that is adapted to be used along the groin region of the user, and a back that is adapted to be used around the back side of the user, where the side edges of the front and the side edges of the back are joined to form a pants shape. The front and rear are each made up of an outer covering obtained by the inaction of an inner layer material and an outer layer material, and the outer cover has several single layer areas formed from the inner layer or outer layer material, where the various single layer areas are arranged at intervals in the length direction of the outer cover, and the laminated areas where the inner layer material and outer layer material are laminated have elasticity in the direction surrounding the waist of the outer cover.
[011] Additionally, the present invention resides in a method of producing a pull-user article. The method of producing a puller article of the present invention comprises: a step of cutting a first laminated material to form an external cover at various points in a lateral direction to thereby form several pieces of the laminated tape-like materials ; a step of inactivating and fixing several pieces of laminated tape-type materials at spaced intervals with the second laminated materials to provide the external cover; a step of orienting the second laminated materials to face inward and thus overlap the outer cover and join the overlapping outer cover at a predetermined interval in the lateral direction of the outer cover; and a step of cutting the outer cover in the joined parts in the lateral direction.
[012] The present invention resides in a method for the production of a pull garment. The method of producing a pull-on garment of the present invention comprises: a step of cutting a first laminated material to constitute an external cover at various points in a lateral direction to form several pieces of the tape-like laminated materials; a step of transporting several pieces of the tape-laminated materials alternatively in different directions while maintaining positions in the lateral direction during cutting, thereby separating the tape-laminated materials into tape-laminated materials to the front and laminated-type materials tape to a rear side; a step of laminating and fixing the respective tape-like laminated materials to the front and back side with separate second laminated materials for the front and back side while maintaining positions in the lateral direction during cutting to provide a continuous element of external cover to be arranged at the front and a continuous element of external cover to be arranged at the rear; a step of adjusting their positions of the continuous outer covering element to be arranged at the front and the continuous external covering element to be arranged at the rear to provide a predetermined interval; a step of fixing an absorbent body in order to create a bridge between the continuous external covering element to be arranged in the front and the continuous external covering element to be arranged in the rear; a step of orienting the second laminated materials to face inwards and, thus, superimpose the continuous external covering element to be disposed in the front and the continuous external covering element to be disposed in the rear, and joining the continuous elements external coverage at a predetermined interval in the lateral direction; and a step of cutting the continuous outer cover elements in the lateral direction in the joined parts.

Description of Modalities
[014] A preferred embodiment (the first embodiment) of the pull garment according to the present invention will be explained below, with reference to the perspective view illustrated in figure 1 and the exploded perspective view illustrated in figure 2.
[015] In the pull clothing items 10 and 100 in this description, the length direction of the pull clothing is defined as Y direction, and the lateral direction of the pull clothing is defined as X direction and also referred to as “Direction around the waist”.
[016] As shown in figure 1 and figure 2, the pull garment 10 of the present embodiment is, for example, a pull diaper, and has a front 21 adapted to be worn around the front side of a a groin part 13 adapted for use along the user's groin region, and a rear part 23 adapted to be used around the user's rear side. This 10 pull diaper will be explained in detail later.
[017] The pull diaper 10 consists of an external cover 11 formed by the front 21 and the rear 23, and an absorbent body 40 that forms the groin part 13.
[018] The outer cover 11 is constituted in a ring shape by joining a side edge 21A of the front 21 and a side edge 23A of the rear 23, and additionally joining the other side edge 21B of the front 21 and an edge side 23B from the rear 23. The side sealing parts 25 are formed at the joined part of the lateral edges 21A and 23A and the joined part of the lateral edges 21B and 23B, respectively.
[019] In addition, the groin part 13 consists of an absorbent body 40 that creates a bridge between the front 21 and the rear 23 and is thus adapted to be used along the user's groin. A pull shape (trousers) consists of the outer cover 11 formed in a ring shape and the absorbent body 40 which creates a bridge at the groin part 13.
[020] The absorbent body 40 that forms the groin portion also extends below a waist opening 12 of the outer cover 11 and is attached to the outer cover 11 on the front 21 and the rear 23. Thus, in the area surrounding the waist, the outer cover 11 has a central area to which the absorbent body 40 is attached, and both side areas to which the absorbent body 40 is not attached. "Area surrounding the waist" mentioned above refers to an area almost from the upper edge of the waist opening 12, to a position below in the length direction (Y direction) close to where the outer top of the thigh is.
[021] The outer cover mentioned above 11 consists of the lamination of an inner layer material 31 and outer layer materials 33, and has several areas of single layer in which a single single layer of inner layer materials 31 is present, in intervals in the length direction (Y direction) of the outer cover 11. In the drawings, a structure is illustrated in which the inner layer material 31 is present in the single layer areas and the outer layer materials 33 are laminated to the inner layer material 31 at intervals along the length of the outlet cover 11.
[022] The laminated area where the inner layer material 31 and the outer layer material 33 are laminated has elasticity in the lateral direction (X direction) of the pull diaper 10. The laminated area may have an elastic member 35 between the inner layer 31 and outer layer materials 33. In such a case, each elastic member 35 is interspersed in its extended state between the inner layer material 31 and the outer layer material 33, and thus has elasticity. Alternatively, as explained in detail below, both or one of the inner layer materials 31 and outer layer materials 33 can be made of an elastic material.
[023] Additionally, it is preferable that the elastic member 35 is cut in several parts so that the laminated areas of the inner layer material 31 and the outer layer materials 33 do not have substantial elasticity in the central area of the outer cover 11 where the body absorbent 40 is fixed.
[024] Since laminated materials for inner layer material 31 and outer layer material 33, for example, non-woven fabrics obtained by various production methods such as air-permeable non-woven fabric, non-woven thermal bearing fabric, rolled non-woven fabric, rolled-up non-woven fabric, and blow-blown non-woven fabric, woven fabrics, knitted fabrics, resin films and the like can be exemplified respectively, and laminated materials formed by integrating them by laminating and the like also can be used.
[025] Additionally, specifically the inner layer material 31 is preferably formed from a non-woven fabric, from the point of view of improving air permeability and texture, and is preferably formed from a water-repellent non-woven fabric, from point of view of preventing leakage of excreted substances.
[026] The elastic elements 25 can be any elastic materials normally used in absorbent articles, such as diapers and sanitary napkins. Examples of such elastic materials include synthetic rubbers, such as styrene-butadiene, butadiene, isoprene, and neoprene, natural rubber, EVA, elastic polyolefins, and polyurethane and the like. Shapes of elastic elements preferably include a cord or thread (a rubber plat) with a rectangular, square, circular or polygonal section or multifilament threads.
[027] Next, the absorbent body 40 will be explained. As illustrated in figure 2, as an example, the absorbent body 40 comprises a topsheet 41, a backsheet 42, and a liquid-retaining absorbent core 43 which is sandwiched between them. This absorbent core 43 is covered by a cover sheet 44, which is folded at the positions of the dotted lines illustrated in the drawing in the directions of the arrow. In addition, a pair of side sheets 46 and 46 that form the internal three-dimensional collections 45 are arranged on the side of the skin contact surface. The aforementioned backsheet 42 and a seam sheet 47 are arranged in that order on the surface side without contact with the skin.
[028] A material that is generally used for this type of diaper can be used for this absorbent body 40, and the material is not specifically limited.
[029] It is preferable that the topsheet 41 be formed of a hydrophilic non-woven fabric. Like hydrophilic non-woven fabric, non-woven fabrics called air-permeable non-woven fabric, a non-woven fabric that is stitched together, a rolled-up non-woven fabric, a rolled non-woven fabric and a three-dimensional non-woven fabric, where the fibers are polypropylene monofilaments, conjugated polypropylene and polyethylene fibers, conjugated polyethylene and polyethylene terephthalate fibers, and the like, which have undergone a hydrophilization treatment, can preferably be used. In addition, a sheet obtained by forming open pores in a resin film can also be used as a top sheet 41.
[030] The backsheet 42 is not specifically limited as long as it has an impermeable property and moisture permeability. For example, a porous film obtained by melt composition of a hydrophobic thermoplastic resin, and a fine inorganic filler comprising calcium carbonate and the like or an organic polymer having no compatibility, and the like to form a film, and subjecting the film to mo - noaxial or biaxial can be exemplified. Examples of thermoplastic resin can include polyolefins. Examples of polyolefins can include high to low density polyethylene, linear low density polyethylene, polypropylene, polybutene and the like, and they can be used alone or by mixing.
[031] For absorbent core 43, for example, those using a fiber aggregate or fiber aggregate and an absorbent polymer in combination, and the like can be used. Like the fibers that make up the aggregate, natural hydrophilic fibers such as pulp fibers and synthetic fibers (preferably fibers undergo a hydrophilization treatment), and the like can be used. Although the base weight is not specifically limited, it is preferably between 150 g / m2 to 500 g / m2. Additionally, for the cover sheet 44, thin paper (tissue paper) such as hydrophilic tissue, non-woven fabrics formed from hydrophilic fibers such as cotton and rayon, non-woven fabrics formed by submitting synthetic resin fibers for a treatment hydrophilization (composite non-woven fabrics such as rolled-fused by blowing-rolled (SMS), rolled-fused by blowing-fused by blowing-rolled (SMMS) and rolled-rolled-fused by blowing-rolled (SSMS)) and the like can be used.
[032] It is preferable to use a water-repellent non-woven fabric for side sheet 46, and rolled non-woven fabric, blowing-rolled rolled-up non-woven fabric (SM), SMS non-woven fabric and the like are especially used. Various non-woven fabrics can be used for the seam sheet 47 to provide a fabric-like appearance.
[033] The pull diaper 10 of this modality has several single layer areas in each of which a single layer of the inner layer material 31 is present without the outer layer material 33, at intervals in the length direction of the outer cover 11 ; therefore, air permeability can be improved in parts of the single-layer areas, while maintaining the same elasticity as a conventional pull diaper and retaining the body's fit and body mobility. Therefore, the formation of vapor can be significantly reduced. Additionally, since the amount of use of the outer layer 33 materials used can be reduced, an environmentally friendly product is provided, and the production cost can be reduced. In addition, the smoothness of the outer covering 11 is improved, and the movement during use becomes smooth and the usability is improved, by the presence of single layer areas.
[034] In the following, examples of the constitutions of disposition of outer layer materials 33, inner layer material 31 and elastic elements 35 for the preferable modality mentioned above will be explained. First, the first example of the pull diaper 10 of the first modality will be explained, and for the other examples and the second modality mentioned below, different points will be explained. The points that are not specifically explained are the same as those of the first modality and the first example, and the explanations described are properly applied. In addition, some symbols are provided for similar materials and parts.
[035] The first example of the pull diaper 10 will be explained by figure 3. As illustrated in figure 3, the pull diaper 10 (10A) of the first example has a structure in which the outer layer materials 33 are attached to the inner layer 31 through elastic elements 35 by an adhesive such as a thermal melting adhesive (not shown) at predetermined intervals in the length direction (Y direction) of the diaper 10 in the diaper mentioned above 10 of the first embodiment. The elastic elements 35 are attached to the outer layer materials 33 and the inner layer material 31 in its extended state. Although the pull diaper 10 has the outer layer materials 33 of the same number as the number of fixed elastic elements 35, several pieces of elastic elements 35 can be arranged in an outer layer material 33. Meanwhile, the increased cross-sectional view of the main part of figure 3 (2) illustrates the state in which the inner layer material 31 is folded back to the side of the skin contact surface in order to cover a part (not shown) to which the absorbent body 40 is fixed.
[036] In the central area of the outer cover 11 where the absorbent body 40 is fixed, the elastic elements 35 are cut through several points, and thus the laminated areas of the inner layer material 31 and the outer layer materials 33 they lack substantial elasticity.
[037] The width of the outer layer 33 material and the intervals for fixing the outer layer 33 materials are properly decided. For example, a width of the outer layer material 33 is preferably approximately similar to or greater than the width of the elastic member 35. For example, it is preferable to adjust the width of the outer layer material 33 to 0.5 mm to 60 mm, and it is preferable to adjust the fixing intervals for outer layer 33 materials to 1 mm to 40 mm. Preferably, the width of the outer layer material 33 is adjusted to 5 mm to 10 mm, and the fixing intervals of the outer layer material 33 are adjusted to 5 mm to 10 mm. When the width and attachment intervals of the outer layer material 33 are adjusted as mentioned above, the wearing comfort of the pull diaper 10 is further improved. Additionally, by adjusting the fixing intervals to equal intervals, an action in which a tension applied to the body by contraction of the elastic elements is evenly distributed, and an effect in which the impression in appearance (aesthetic impression provided by regularity ) is improved can also be obtained.
[038] Since the side steering end parts (the end parts towards the diaper length) of the outer layer materials 33 are free ends, when the stretch load of the elastic elements 35 is released, the layer materials outer 33 contract due to the contraction of the elastic elements to form ornaments 36 (see enlarged perspective view). Therefore, there is an action in which a beautiful appearance can be created as the whole diaper. In addition, the fixing position of the outer layer material 33 for the inner layer material 31 is not limited to the central part of the outer layer material 33 in the lateral direction (Y direction), and can be offset in any of the lateral directions. That is, in the lateral direction of the outer layer material 33, the distance from the clamping position for the inner layer material 31 to one edge can be long and the distance to the other edge can be short. By changing the distances from the fixing position to the edges in this way, the ornaments are easily formed over a greater distance.
[039] Additionally, the side sealing parts 25 are parts where the side edges of the front 21 of the outer cover 11 and the side edges of the rear 23 of the outer cover 11 are respectively joined by sealing such as embossing. For example, the inner layer material 31 (31 A) of the front 21 and the inner layer material 31 (31B) of the rear 23 are joined in the state in which the outer layer material 33 (33A) of the front 21 and the outer layer material 33 (33B) of the front 21 facing each other. Therefore, in the side sealing part 25, the elastic member 35 (35A) disposed in the front 21 and the elastic member 35 (35B) disposed in the rear 23 are disposed in a state in which they face each other through the material inner layer 31.
[040] This structure can also be applied to an example using the elastic elements 35 explained below, and for the second modality. In addition, this structure can also be applied to an example in which the elastic elements 35 are not used mentioned below, except for the elastic elements 35.
[041] In the side sealing part mentioned above 25, the part where the inner layer material 31 and the outer layer material 33 are laminated becomes a part where the bond strength is strong, and the part having only the inner layer 31 becomes a part where resistance to the joint is weak. Therefore, the joined part is easily removed in the area having only the inner layer material. Additionally, since the side sealing part 25 has the areas having only the inner layer material 31, the flexibility of the side sealing part 25 is improved, the wearing comfort is improved, and the touch with the skin and texture of the surface side of skin contact are further improved.
[042] Like the materials for the inner layer material 31 and outer layer materials 33, the sheets explained in the first embodiment mentioned above can be used. The elastic elements 25 can be any of the elastic materials normally used in absorbent articles, such as diapers and sanitary napkins. Examples of such elastic materials include synthetic rubbers, such as styrene-butadiene, butadiene, isoprene, and neoprene, natural rubber, EVA, elastic polyolefins, and polyurethane. Shapes of elastic elements preferably include a thread or cord (a rubber plat) with a rectangular, square, circular or polygonal section or multifilament threads.
[043] In the first example of the 10A pull diaper, the effects mentioned for the 10 pull diaper in the first embodiment can be obtained. Additionally, the elasticity is printed to the outer covering 11 in the laminated areas of the outer layer materials 33 and inner layer material 31 where the elastic elements 35 are arranged. This elasticity improves the diaper's ability to pull on the body. As illustrated in the perspective view enlarged in figure 3 (1). Since the side steering end parts (the end parts towards the length of the diaper) of the outer layer materials 33 are free ends, when the load to stretch the elastic elements 35 is released, the outer layer materials 33 become they contract due to the contraction of the elastic elements to form ornaments 36. Therefore, there is an action in which the pleasant appearance can be created as the entire diaper. Additionally, since the elastic elements 35 are covered with the outer layer materials 33, the elastic elements 35 are protected by the outer layer materials 33. Thus, the direct application of external force to the outer layer materials 33 is prevented, and, in this way, the elastic elements 35 become difficult to cut.
[044] Additionally, as illustrated in figure 4, colored or printed sheets can be used for outer layer materials 33. By using such sheets (the strip-like sheets that are photographed thickly in the lateral direction in the photograph), the laminated areas they are easily distinguished, and it is possible to provide the pull diaper 10 which is excellent in terms of designs.
[045] Although the first example shown in figure 3 illustrates a structure in which the outer layer materials 33 are attached to the inner layer material 31 through the elastic elements 35 at predetermined intervals, for example, conversely, a structure in which the cut inner layer materials 31 are fixed to the outer layer material 33 through the elastic elements 35 at predetermined intervals by a thermal melt adhesive can also be used.
[046] Next, the second example of the pull diaper 10 will be explained by figure 5. As illustrated in figure 5, the pull diaper 10 (10B) of the second example has a structure in which the outer layer materials 33 are fixed in the inner layer material 31 through elastic elements 35 at predetermined intervals by the sealing parts 37 in the pulling diaper 10 of the first embodiment mentioned above. The width of the outer layer material 33 and the gap between the outer layer materials 33 are in accordance with the first example. In this structure, the respective elastic elements 35 are in an extended state and both ends of them are fixed by joining with an adhesive 39 to thereby give elasticity to the entire outer covering 11. Each elastic member 35 is not fixed to the material outer layer 33 and inner layer material 31 in parts beyond both ends thereof. Therefore, the thin elasticity can be obtained in the laminated areas of the outer layer materials 33 and inner layer material 31 without inhibiting the elasticity of the elastic elements 35. In the central area of the outer cover 11 where the absorbent body 40 is fixed, the laminated areas of outer layer materials 33 and inner layer material 31 have elasticity.
[047] Additionally, in this structure, collections can be made by arranging sealing parts 37 regularly in the parts where the inner layer material 31 and the outer layer materials 33 form two layers with elastic elements 35 interspersed between them. In this second example, air permeability is improved since the spaces that allow ventilation in the length direction (Y direction) in the parts between the outer layer materials 33 and the inner layer material 31 are created by the collections. Additionally, the collections print an impression on the design for the products.
[048] In the pull diaper 10 (10B) of the second example, similar effects to the pull diaper 10 of the first embodiment mentioned above can be obtained. Additionally, since the outer layer materials 33 are attached to the inner layer material 31 by forming sealing parts 37 at intervals on the sides in the direction surrounding the waist of the outer layer materials 33, air permeability can also be obtained in the lateral direction (Y direction illustrated by an arrow in the drawing) of the outer layer materials 33 between the outer layer materials 33 and the inner layer material 31. Therefore, air permeability can also be guaranteed in the parts of the outer layer materials. inner layer 31 with outer layer materials 33, in addition to air permeability in parts of inner layer material 31 without outer layer materials 33. Accordingly, the diaper to pull 10 (10B) which does not lose its softness, it is excellent in terms of elasticity, it has a fine air permeability and it is very difficult to make wet it can be supplied, despite the fact that the outer covering 11 has laminated areas.
[049] The third example of the pull diaper 10 will be explained by figure 6. As illustrated in figure 6, the pull diaper 10 of the third example (10C) has a structure in which the outer layer materials 33 themselves have elasticity in longitudinal direction (direction around the waist), and these outer layer materials 33 are attached to the inner layer material 31 in an extended state by an adhesive 32, in the pull diaper 10 of the first embodiment mentioned above. As the adhesive, for example, a thermal fusion adhesive, double-sided adhesive tape and the like are used.
[050] The elasticity that the outer layer 33 materials themselves have, as used here, refers, for example, to the elasticity that can replace the elasticity that is printed by the elastic elements mentioned above.
[051] As the outer layer 33 materials having elasticity, elastic sheets such as non-woven fabrics comprising elastic fibers and elastic films can be used. In the case where texture and fabric-like appearance are emphasized, it is preferable that these elastic sheets have a fiber layer on the surface. In the case where this fiber layer is not elastic, the fiber layer can be stretched by a stretch or similar processing so that the non-elastic fiber layer does not inhibit the elasticity of the elastic sheet. As the stretch processing, for example, a groove processing with cutting tooth between the fibers or stretching of fibers, partially in the fiber layer, is exemplified, and thus, the elasticity is expressed without inhibiting the elasticity of the elastic sheet. By processing the groove and tooth on the surface of the fiber layer, as illustrated in the enlarged plane view of the main part of figure 6 (3), concave and convex parts (the concave being groove 34) are formed on the surfaces of the outer layer materials 33.
[052] The groove intervals mentioned above 34 are adjusted, for example, in equal intervals. Additionally, in the case where the degree of impression of elasticity is changed in each position, it is also possible to change the groove intervals 34. For example, in the case where the thickness of the outer layer materials 33 is 0.01 mm to 0 , 2 mm, in an area where strong elasticity is desired, groove intervals 34 are adjusted to about 2 mm to 5 mm, and in an area where weak elasticity is desired, groove intervals 34 are adjusted to approximately from 0.5 mm to 2 mm. The groove intervals 34 are also changed depending on the thickness of the outer layer materials 33. The method of processing the outer layer materials 33 is not limited as long as the outer layer materials have the desired elasticity by the grooves 34.
[053] Additionally, the width of the outer layer material 33, and the intervals of the outer layer material 33 are in accordance with the first example.
[054] In addition, tooth and groove processing as a stretch processing is also conducted on the outer layer materials 33 on the absorbent body 40. After the stretch processing, the outer layer materials 33 are elongated and joined to the layer material inner 31. After joining, the outer layer materials 33 and the inner layer material 31 are heat sealed (the elastic elements are cut) in the corresponding parts in the absorbent body 40, so that the outer layer materials 33 are made inelastic and lose their elasticity in the corresponding parts, and then the teeth and grooves formed in the outer layer materials 33 in the absorbent body 40 become less prominent.
[055] As the outer layer materials mentioned above having elasticity, for example, (1) a sheet comprising an elastic fiber layer and an extensible fiber layer that is integrated with one or both surfaces of the elastic fiber layer, ( 2) a sheet comprising an elastic net-like sheet and a layer of extensible fiber that is integrated with one or both surfaces of the elastic sheet, (3) a sheet comprising an elastic sheet formed of an elastic film and a layer of extensible fiber which is integrated with one or both surfaces of the elastic sheet, (4) an elastic sheet in which many elastic filaments arranged to be extensible in one direction without forming an intersection with each other are joined to an extensible non-woven fabric, substantially in one it is inextensible, through its entire length.
[056] Like the sheet mentioned above (1), for example, (a) an elastic non-woven fabric in which a substantially non-elastic fiber layer is arranged on at least one surface of an elastic fiber layer, where both layers fibers are joined to the entire surface by thermally fusing the fiber intersection points in the state in which the constitutional fibers in the elastic fiber layer retain the fiber shapes, and the non-woven fabric is not in the state in which the part of the constitutional fibers in the non-elastic fiber layer penetrated the elastic fiber layer, and the state in which a part of the constitutional fibers in the elastic fiber layer penetrated the non-elastic fiber layer, or in both states, can be exemplified. Additionally, like the sheets of (1) to (3) mentioned above, (b) an elastic sheet having an elastic layer with elastic stretch and a layer of substantially non-elastic fiber, where two layers are created on a laminated sheet by laminating in its direction of thickness and partially joining and a drawing is carried out on the laminated sheet, and the like can preferably be used. As a means for these stretches and for obtaining the extensible fiber layers and non-woven fabrics from (1) to (3) mentioned above, it is preferable to conduct the above mentioned tooth and groove processing.
[057] As the elastic non-woven fabric of (a) mentioned above, at the interface of the elastic fiber layer and non-elastic fiber layer and in the vicinity thereof, the points of intersection of the fibers constituting the elastic fiber layer and the fibers constituting the non-elastic fiber layer are joined by thermal fusion, and thus are also joined substantially across the surface. Since two layers are joined across the surface, the force of spaces by separating the two layers is prevented, and an elastic non-woven fabric having a multilayer structure that provides the feeling of unity as a single layer non-woven fabric It is formed. The state mentioned above that the fibers constituting the elastic fiber layer retain the shapes of the fiber refers to a state that most of the constituting fibers in the elastic fiber layer are not deformed into a film format, or a structure of film comprising fibers, even in the case where heat, pressure or the like are applied. In addition, in the elastic fiber layer, the intersection points of the constitution fibers are joined by thermal fusion in the layer. Similarly, also in the non-elastic fiber layer, the intersection points of the constitution fibers are joined by thermal fusion in the layer.
[058] In the case where the layers of non-elastic fiber are disposed on both surfaces of the elastic fiber layer, at least one of the surfaces is in the state in which a part of the constituting fibers has penetrated the elastic fiber layer, or the state in which a part of the constituting fibers in the elastic fiber layer has penetrated at least one of the non-elastic fiber layers, or in both states.
[059] The elastic fiber layer has a property of being able to be stretched, and it has a property of contracting when it is released from the load for stretching. Additionally, it is an aggregate of fibers having elasticity. In addition, the elastic fiber layer may be in the form of a canvas or non-woven fabric formed of fibers having elasticity. For example, it can be a non-woven fabric formed by a blowing winding process, a winding joining process, a blowing fusion process or the like. Specifically, a web obtained by a winding after blowing process is preferable. As constituting fibers for the elastic fiber layer, for example, fibers obtained from raw materials such as thermoplastic elastomers and rubbers can be used. Specifically, fibers obtained from thermoplastic elastomers as raw materials are preferable for non-woven fabric that can be stretched in the modality comprising an air-permeable non-woven fabric as a basic constitution, since the melt winding using an extruder as in Thermoplastic resins are generally possible, and the fibers obtained in such a way are easily joined by thermal fusion. Examples of thermoplastic elastomers may include styrene-based elastomers such as SBS, SIS, SEBS and SEPS, olefin-based elastomers, polyester-based elastomers, and polyurethane-based elastomers. These can be used for one type only or for a combination of two or more types.
[060] The non-elastic fiber layer has extensibility, but is substantially non-elastic. The extensibility as used here can be one of the case where the constitution fibers themselves elongate, and the case in which the constitution fibers themselves do not elongate, but the entire fiber layer elongates due to a separation of the fibers that they are joined by thermal fusion at the points of intersection of the fibers, a change of structure in the three-dimensional structure formed of several pieces of fiber by the union by thermal fusion of the fibers and the like, or a tear of the constitution fibers. Examples of fibers that make up the non-elastic fiber layer may include fibers formed from polyethylene (PE), polypropylene (PP), polyesters (PET and PBT), polyamides and the like. The fibers that make up the non-elastic fiber layer can be short or long fibers and can be hydrophilic or water-repellent. In addition, conjugated fibers such as core sheath or side-by-side, divisible fibers, fibers with modified cross-surface, tight fibers, heat shrunk fibers, and the like can also be used. These fibers can be used alone for one type or as a combination of two or more types. The non-elastic fiber layer may be a nonwoven fabric or fabric of continuous filaments or short fibers.
[061] The elastic sheet of (b) mentioned above is obtained by conducting a stretch processing on a laminated sheet comprising an elastic layer having elastic stretch capability and substantially inelastic fiber layers that are laminated to one or both surfaces of the elastic layer, where the non-elastic fiber layers are partially joined in a regulated pattern.
[062] The effects of the pull diaper 10 (10C) of the third example are as mentioned in the pull diaper 10 of the first embodiment mentioned above. In this example, since the outer layer materials 33 undergo stretch processing in order to have a concave and a convex part, without requiring elastic elements that are disposed between the inner layer material 31 and the outer layer materials 33 , smooth appearance and touch are provided, and ornaments can also be formed on the outer layer materials 33 by narrowing the width of application of the adhesive 32 with respect to the width of the outer layer material 33. Additionally, the materials for the elastic elements can be reduced.
[063] Additionally, by changing the widths of the outer layer 33 materials, the elastic force is also changed and can be adjusted to an adequate constriction pressure corresponding to each location such as a waist part, an ilium and lumbar part. For example, by increasing the width more at the waist and at the ilium than at these other locations, the elastic strength can be improved and the constriction pressure can be increased.
[064] In the pull diaper 10 of the third example, in the case where the elasticity of the laminated areas is weak, the elastic member 35 of the first example can be interleaved between the outer layer materials 33 and the inner layer material 31 as needed.
[065] The fourth example of the pull diaper 10 will be explained in figure 7. In the fourth example of the pull diaper 10 (10D), materials similar to the pull diaper 10A of the first example mentioned above are used in the pull diaper 10 of the first modality mentioned above. In the pull diaper 10 of the first example mentioned above, as shown in figure 7, the outer layer materials 33 and the inner layer material 31 are fixed by an adhesive such as a thermal melting adhesive (not shown) through the elastic elements 35 underwent stretching processing (such as tooth and groove processing) in the direction surrounding the waist (X direction). Thus, the outer layer materials 33 and the inner chamber material 31 have an extensibility. The elastic elements 35 are attached to the outer layer materials 33 and the inner layer material 31 in their extended state. As mentioned above, the processing method for stretching processing is not limited as long as it is a method that makes the outer layer materials 33 and the inner layer material 31 extensible.
[066] Additionally, the width of the outer layer material 33 and the gaps between the outer layer materials 33 are according to the first example mentioned above.
[067] In the fourth example of the 10 diaper (10D), similar effects to the 10A diaper of the first example mentioned above can be obtained. Additionally, by conducting a tooth and groove processing as a stretch processing, the outer layer materials 33 and the inner layer material 31 can be made extensible. Thus, the elasticity is expressed without inhibiting the elasticity of the elastic elements 35, and, thus, the fit of the pull diaper 10D can be improved.
[068] The fifth example of the pull diaper 10 will be explained in figure 8. As illustrated in figure 8, the pull diaper 10 (10E) of the fourth example has a constitution in which the pores 15 are formed in an outer covering 11 of the part of the inner layer material 31 where the outer layer materials 33 are not arranged in the pull diaper 10 of the first embodiment mentioned above. This constitution can be applied to pull diapers 10 of all constitutions that are explained in the description. The pores 15 are formed at predetermined intervals. For example, it is preferable that the pores each have a diameter that is less than at least the disposition interval between the outer layer materials 33, depending on the disposition intervals of the outer layer materials 33, and that the interval between the pores it is adjusted to, for example, 101% or more and 500% or less of the diameter of the pore 15. More preferably, the pore range is adjusted to 200% or more and 300% or less of the diameter of the pore 15. The pores 15 can be formed by a heated needle, laser processing or the like.
[069] The pull diaper 10 of the fifth example (10E) also exhibits effects similar to the pull diaper 10 of the first modality mentioned above. In this example, since pores 15 are formed in the inner layer material 31, air permeability is further improved.
[070] In the following, the second embodiment of the pull diaper of the present invention will be explained with reference to figure 9.
[071] As illustrated in figure 9, the pull diaper 100 as an example of a pull diaper has a constitution in which an outer cover 11 is also formed in a groin part 13, and an absorbent body 40 is disposed inside ( side of the skin contact surface) of the outer cover 11 formed on the groin part 13. Specifically, the pull diaper 10 has the groin part 13 which is formed so as to create a continuous bridge between the front 21 and the rear 23 for external cover 11 in the first embodiment mentioned above. The inner layer material 31 is formed on the back 23, the front 21 and groin part 13 of the outer cover mentioned above 11, and the outer layer materials 33 are laminated at intervals on the inner layer material 31 on the back 23 and front 21 along the direction surrounding the waist (X direction). Therefore, the outer layer materials 33 are not laminated to the inner layer material 31 in the groin part 13.
[072] As mentioned above, the constitution of the outer layer materials 33 according to the present invention can also be applied to the pull diaper 100 having the outer cover which is formed continuously from the front side to the rear side through the groin , and can improve the air permeability of the pull diaper. In addition, the materials used for the outer layer 33 materials can be reduced, and thus the production cost can be reduced.
[073] In the following, the first aspect of a preferred embodiment (the first embodiment) of the production method of a pull diaper of the present invention will be explained below, with reference to figures 10 to 13. The first aspect of the production method is a production method of the pull diaper mentioned above 10 (10A). For points that are not specifically explained in other aspects mentioned below, the explanations that are mentioned in detail with respect to the first aspect are properly applied.
[074] As illustrated in figures 10 to 13, for example, a first laminated material 1S is fed from the upper side, a second laminated material S2 is fed from the lower side, and a continuous elastic element 3S, which makes elastic elements 35, is fed into the space between the first laminated material 1S and the second laminated material 2S. The first laminated material 1S forms the outer layer materials 33, and the second laminated material 2S forms an inner layer material 31. For that first laminated material 1S (outer layer materials 33), the second laminated material 2S (inner layer material 31) and continuous element of elastic member 3S (elastic elements 35), materials similar to those mentioned respectively above in the pull diaper 10 are used.
[075] Firstly, the first laminated material mentioned above 2S is divided into several pieces in the lateral direction by an outer layer material cutter 211 to thereby form narrow ribbon type 33T laminated materials. The laminated materials 33T and 33T are then spaced at predetermined intervals d1 by a spacing device 213. The width of the laminated material 33T (the divided part of the first laminated material 1S) is formed in the width of each outer layer material 33 (33A, 33B) in the aforementioned pull diaper 10A, and the gap by the spacing is also formed in the gap of the outer layer materials 33 in the aforementioned pull diaper 10A.
[076] Although not shown in the drawings, the aforementioned spacing device comprises a device equipped with guide rollers for the respective tape-like laminated materials, which is configured to extend the intervals to intervals predetermined by the angles and positions of the roll arrangement for , in this way, converge the laminated materials like tape and the second laminated material 2S, or a device equipped with guides to adjust the laminated flow (an equipment to correct snaking) to the respective laminated materials like tape, which is configured to converge the materials tape-type laminates and the second 2S laminated material.
[077] Additionally, several pieces of the continuous members of elastic member 3S are prepared in parallel and fed together with the second laminated material 2S in the state in which the respective continuous members of elastic member are extended and an adhesive (not shown) fed by an adhesive coating apparatus 215 is applied to it. The respective elastic member continuous elements 3S are fed at predetermined intervals d2. At that time, it is preferable that they are fed so that the center of the lateral direction of the continuous member of elastic member 3S is positioned in the center of the lateral direction of the aforementioned tape-like laminated material 33T. For example, a thermal melt gun is used as the adhesive coating apparatus mentioned above 215, and a thermal melt adhesive is used as the adhesive in that case.
[078] Thus, the continuous elements of the elastic member 3S at predetermined intervals d2 are fed into the space between the narrowing cylinders 217 and 218 in their extended state in the second laminated material 2S. At the same time, each 33T tape-type laminated material is fed into each continuous elastic member element such that the continuous member of the elastic member 3S is positioned in the center of the lateral direction of the 33T tape-like laminated materials.
[079] Additionally, the second 2S laminated material, the 3S elastic member continuous elements and the 33T tape-type laminated materials are passed between the narrowing cylinders 217 and 218, and the second 2S laminate material and the 33T-tape laminated materials are passed. adhered by continuous elements of elastic member 3S by the thermal melting adhesive applied to continuous elements of elastic member 3S by the pressure between the cylinders, thereby providing a continuous element of external cover 11S which must be an external cover 11. Meanwhile , by feeding the adhesive to one or both of the 33T tape-type laminated materials and the second 2S laminated material to the adhesive coating apparatus 215, the continuous elastic member elements are adhered to the materials.
[080] Next, a step of cutting the elastic member to deactivate the expression of the elastic function of the continuous elements of elastic member 3S in the part of the second laminated material 2S where the absorbent body 40 is fixed is conducted. In this elastic member cutting process, for example, a non-functionalized area 11N can be formed in the continuous element of the outer cover 11S by using a cutting cylinder 219 with a non-functionalized area forming part (not shown) that deactivates the expression of the contraction force of the continuous elements of the elastic member 3S. The non-functionalized area forming part consists of many convex parts or cutter blades that are configured to cut the continuous elements of the elastic member 3S, or many embossing pins that are configured to cure the continuous elements of the elastic member 3S by sealing thermal, or similar.
[081] A cylinder 220 corresponding to the cutting cylinder 219 is a receiving cylinder of the cutting cylinder, and its peripheral surface is a smooth surface.
[082] Next, the continuous element of the outer cover 11S is cut in the central part in its lateral direction using an outer cover cutter 221, and spaced at a predetermined interval so that the front 21 and the rear 23 are formed. The size and similars of the pull diaper 10 including this predetermined interval are selected appropriately depending on the size and intended use.
[083] Next, the absorbent body 40 which is obtained by cutting a continuous body of the absorbent body 40S fed from an absorbent body forming part 4, is arranged in the predetermined positions of the front 21 and rear 23 of the continuous element of external cover 11S. At that time, the absorbent body 40 is arranged so that the longitudinal direction of it becomes, for example, at right angles with the front 21 and the rear 23. The absorbent body 40 is fixed to the continuous outer cover element 11S while maintains the extended state of the continuous outer cover element 11S. For example, the absorbent body 40 is fixed while maintaining the continuous outer covering element 11S so as not to shrink by the contraction force of the continuous element of the elastic member 3S. Generally, an elastic member that contracts in the longitudinal direction of the absorbent body 40 is also disposed on the absorbent body 40, and also in such a case, the absorbent body 40 is attached to the continuous outer covering element 11S while maintaining the absorbent body 40 so as not to contract . At that time, an adhesive is applied in advance to the absorbent body 40 or continuous outer covering element 11S.
[084] Subsequently, the end parts on the outer side of the lateral direction of the continuous element of the outer cover 11S are folded back to cover both end parts in the longitudinal direction of the absorbent body 40 and the absorbent body 40 is fixed to the parts folded back. In doing so, an adhesive is applied in advance at the predetermined positions on the inner sides of the folded back parts, to the absorbent body 40 and the like.
[085] Next, the longitudinal direction of the absorbent body 40 is folded in two, and the front portion 21 of the outer covering element 11S and the rear portion 23 of the outer covering element 11S are overlapping while orienting the second laminated materials 2S to turn inward. Subsequently, a lateral sealing step to join the front 21 and the rear 23 in the lateral direction of them at a predetermined interval is conducted. The predetermined interval in this side sealing step determines the length in the lateral direction of the pull diaper 10. Thus, a continuous body of pull diaper 10S is obtained.
[086] Subsequently, the continuous 10S pull diaper body is cut in the lateral direction in the unit parts obtained by the side seal. As a result, a pull diaper 10 (10A) is completed, and, thus, the constitution as explained in the first example of the pull diaper mentioned above can be obtained.
[087] In the first aspect mentioned above of the production method, single layer regions formed from the inner layer material 31 are formed by rolling several pieces of the 33T tape-type laminated materials, which are formed by cutting the first 1S laminated material , with the second laminated material 2S in the state in which the respective 33T tape-type laminated materials are spaced. Thus, air permeability is greatly increased in the single layer area, and thus, the 10 (10A) pull diaper in which the humidity is significantly reduced can be provided.
[088] Additionally, since the amount of use of outer layer 33 materials can be reduced, an environmentally friendly product can be produced in a disposable pull diaper. Additionally, since the amount of use of outer layer materials 33 can be reduced, the cost of production can be reduced.
[089] Next, the second aspect of the production method of the present invention will now be explained below, with reference to the planar view (1) and the front view (2) illustrating the main part of figure 14. The second aspect is a method for the production of the pull diaper mentioned above 10 (10B).
[090] As illustrated in figure 14, for example, a first laminated material 1S is fed from the upper side, a second laminated material 2S is fed from the lower side, and a continuous element of the elastic member 3S, which will become the elastic elements 35, are fed into the space between the first laminated material 1S and the second laminated material 2S. The first laminated material 1S forms the outer layer materials 33, and the second laminated material 2S forms an inner layer material 31. For these first laminated material 1S (outer layer materials 33), the second laminated material 2S (inner layer material 31) and continuous element of elastic member 3S (elastic elements 35), materials similar to those mentioned above in the pull diaper 10 respectively are used.
[091] First, the first laminated material mentioned above 1S is divided into several pieces in the lateral direction by an outer layer material cutter 211 to form 33T narrow ribbon laminated materials, and the 33T and 33T ribbon laminated materials are spaced at predetermined intervals d1 by a spacing device 213 which is similar to that explained in the first aspect mentioned above. The width of the 33T tape-type laminate (the first 1S split laminate material) is similar to the width of the outer layer material 33 of the pull diaper mentioned above 10A, and the intervals are similar to the intervals of the outer layer materials 33 in the diaper. pull mentioned above 10A.
[092] Additionally, several pieces of elastic elements 35 are prepared in parallel and fed together with the second laminated material 2S in its extended state, and in the state in which an adhesive (not shown) fed by an adhesive coating device 215 is applied . The continuous elements of the respective elastic member 3S are fed at predetermined intervals d2. This adhesive is fed intermittently. For example, as illustrated in figure 5 mentioned above, the adhesive is applied to the parts of the continuous elements of the elastic member 3S (the elastic elements 35) which are arranged in the respective positions of: outer edge parts of the absorbent body 40 fixed to the front 21 and rear 23 of the outer cover 11 which is formed by the second laminated material 2S; both ends of the direction surrounding the front waist 21; and both end parts in the direction surrounding the waist of the rear part 23. At that time, the continuous elements of the elastic member 3S are fed so that the center of the lateral direction of the continuous element of the elastic member 3S corresponds to the center of the lateral direction of 33T tape-type laminated material.
[093] Like the adhesive coating apparatus mentioned above 215, a thermal melting gun or similar is used, and a thermal melting adhesive is used as the adhesive in this case.
[094] Thus, the second laminated material 2S, the continuous elements of the elastic member 3S and the laminated materials like ribbon 33T are passed between narrowing cylinders 217 and 218. Additionally, the second laminated material 2S and the rolled materials like ribbon 33T partially adhered through the continuous elements of the elastic member 3S by the thermal melting adhesive applied to the continuous elements of the elastic member 3S by the pressure between the cylinders.
[095] The width of the 33T tape-laminated material, and the 33T tape-laminate material ranges are in accordance with the pull diaper mentioned above 10A.
[096] Next, a sealing processing in which the first laminated material 1S, the continuous elements of the elastic member 3S and the second laminated material 2S salt are partially additions are passed through the sealing cylinders 231 in an overlapped state. By these sealing cylinders 231, the sealed parts 37 are formed at intervals on both sides in the lateral direction of the tape-like laminated materials 33T, and the tape-like laminated materials 33T are fixed in the second laminated material 2S. It is preferable to use the engraving joint for forming the sealed parts 37. By using the engraving joint, the fold of the laminated material is not lost by curing the adhesive and the like, and in this way, a fine texture can be maintained.
[097] In addition, the continuous elements of the elastic member 3S are present between the 33T tape laminated materials and the second 2S laminated material and between the sealing parts 37 and 37 and are also intermittently fixed in the 33T tape laminated materials and second material 2S laminated by the adhesive in the step mentioned above. Therefore, most of the continuous elements of the elastic member 3S are free from the 33T tape-type laminated materials and the second 2S laminated material. Thus, the air permeability of 33T tape-type laminated materials (outer layer materials 33) in the lateral direction can be improved.
[098] Additionally, in the sealing step mentioned above, the sealed parts 37 are formed in a regulated manner in the parts of the non-woven fabric where the 33T tape-type laminated materials and the second 2S laminated material form two layers by the interposition between them of continuous elements of elastic member 3S in its extended state, so that collections (not shown) can be formed by laminated materials like ribbon 33T (outer layer materials 33) when continuous members of elastic member (elastic elements 35) contract . That is, the parts between parts intermittently fixed in the 33T tape-type laminated materials are lifted out (the surface side without contact with the skin) by the contraction of the elastic elements formed in the continuous elements of the elastic member 3S. Thus, the collections mentioned above are formed.
[099] Thus, the continuous element of the outer cover 11S that should be the outer cover 11 is obtained.
[0100] Next, the steps in and after the cutting step of the elastic member using cutting rollers 219 as explained in the first aspect mentioned above are subsequently conducted to thereby complete the 10 (10B) pull diaper (for example , see the one mentioned above in figure 5). In this respect, in the step of cutting the elastic member, the elastic elements 35 are each cut in a part in the central position of the area in which the absorbent is arranged. Alternatively, since the step of cutting the elastic member is not essential, it is not necessary to cut the elastic elements 35.
[0101] In the second aspect of the production method of the present invention, effects similar to those of the first aspect mentioned above can be obtained, and the air permeability of the areas in which the 33T tape-laminated materials (the outer layer 33 materials) are trained can be improved. Additionally, collections can be formed in the lateral direction of the outer layer 33 materials simultaneously with the fixation of the 33T tape-type laminated materials. Thus, decorative static printing can be provided.
[0102] Additionally, when fixing the continuous elements of the elastic member to the first laminated material 1S or the second laminated material 2S and the fixing of the first laminated material 1S and the second laminated material 2S, more adhesive becomes unnecessary, and thus, it becomes reduction of the environmental load is possible, and the cost is reduced, compared to the first aspect.
[0103] Next, the third aspect of the production method of the present invention will be explained below, with reference to the plan view (1) and the front view (2) illustrating the main part of figure 15. The third aspect is a method of production of the pull diaper mentioned above 10 (10C).
[0104] As illustrated in figure 15, a first laminated material 1S is fed from the upper side, and a second laminated material 2S is fed from the lower side. The first laminated material 1S forms the outer layer materials 33 and itself has elasticity in the longitudinal direction (direction around the waist). An example is one having a first layer on the surface of an elastic sheet. Therefore, as different from the first aspect mentioned above, elastic elements 35 are not used. The second laminated material 2S forms an inner layer material 31.
[0105] First, the entire surface area of the first laminated material mentioned above 1S is subjected to tooth and groove processing as a drawing process, using a concave-convex cylinder 241. As a result, grooves 34 ( illustration after cutting the first laminated material 1S is omitted) are printed on the first laminated material 1S in the lateral direction. Through this tooth and groove processing, the extension capacity is printed on the fiber layer in the first 1S laminated material in the longitudinal direction of it, without inhibiting the elasticity of the elastic sheet, in order to allow the first 1S laminated material to express elasticity. The groove intervals 34 are adjusted depending on the thickness of the non-woven fabric of the first laminated material 1S and, for example, just at intervals that are in accordance with the aforementioned pull diaper 10C. Additionally, a concave-convex cylinder 242 that engages the concave-convex cylinder 241 is arranged in the position corresponding to cylinder 241.
[0106] Next, the first 1S laminated material that underwent tooth and groove processing mentioned above is divided into several pieces by an outer layer material cutter 211 to provide 33T tape-type laminated materials. In addition, the laminated materials such as tape 33T and 33T are spaced at predetermined intervals d1 by a spacing device similar to 213 as explained in the first aspect mentioned above. The width of the 33T tape-type laminate material, and the ranges of the 33T tape-type materials are in accordance with the aforementioned pull diaper 10A. In addition, the tooth and groove processing mentioned above can be conducted after splitting the first laminated material 1S into several pieces by the outer layer material cutter 211.
[0107] On the other hand, the second laminated material 2S is fed in the state in which the adhesive (not shown) fed by the adhesive coating apparatus 215 is applied to it. It is preferable that the adhesive is fed approximately in the central part of the position to which each of the 33T tape-laminated materials is attached in the subsequent step, and the method of feeding can be continuous or intermittent.
[0108] Thus, the 33T tape-laminated materials are fed at predetermined intervals in the second 2S laminated material between the narrowing rollers 217 and 218. Additionally, by passing the second laminated material mentioned above 2S and the 33T tape-laminated materials between the narrowing cylinders 217 and 218, the second laminated material 2S and the laminated materials type tape 33T are added by the adhesive applied to the second laminated material 2S by the pressure between the cylinders.
[0109] As a result, a continuous element of the outer cover 11S that is about to become the outer cover 11 is obtained.
[0110] In the following, the steps in and after the step of cutting the outer cover using the outer cover cutter 221 explained in the first aspect of the production method mentioned above of the present invention are subsequently conducted to, in this way, complete the diaper of pull 10 (10C) (for example, see figure 6 mentioned above).
[0111] In the third aspect of the production method of the present invention, effects similar to those of the first aspect mentioned above can be obtained. In addition, since elasticity is printed on the 33T tape-laminated materials themselves, it is not necessary to have elastic elements between the first 1S laminate material (the outer layer 33 material) and the second 2S laminate material (the inner layer material 31 ), and this allows for the reduction of materials and the reduction of material costs.
[0112] Next, the fourth aspect of the production method of the present invention will be explained below, with reference to the pan view (1) and the front view (2) illustrating the main part of figure 16. The fourth aspect is a method of production of the pull diaper mentioned above 10 (10D).
[0113] The fourth aspect is a production method comprising conducting a tooth and groove processing as a stretching step, between the step of adhering the second 2S laminated material to the second 2S laminated material and the 33T tape-type laminated materials ( the first laminated material 1S) to be the outer layer materials 33, through the continuous elements of the elastic member 3S by the narrowing cylinders 217 and 218, and the step of cutting the elastic elements by the cutting cylinder 219, in the first aspect mentioned above . The fourth aspect is similar to the first aspect mentioned above except that tooth and groove processing is conducted. Tooth and groove processing as used here is a step of printing the extensibility to the fiber layer without inhibiting, for example, the extensibility of the extensible sheet constituting the outer layer materials 33, by the pressure of the blades of the conical cylinder. - concave-convex 241 against 33T tape-laminated materials and inner layer material 31. As a result, grooves 34 are printed to 33T-tape laminated materials at intervals. It is preferable that the groove intervals 34 are adjusted, for example, to similar intervals to the grooves of the aforementioned pull diaper 10C. Additionally, a concave-convex cylinder 242 that engages with the concave-convex cylinder 241 is arranged in the position corresponding to cylinder 241.
[0114] First, in a similar way to the first aspect mentioned above, the 33T narrow ribbon laminated materials, which are obtained by dividing a first 1S laminated material into several pieces, are fixed to the second 2S laminated material (the layer material internal 31). For example, 33T tape-type laminated materials are non-elastic non-woven fabric. Subsequently, the 33T tape-type laminated materials and the inner layer material 31, which are adhered through the intervention of continuous elements of the elastic member 3S, undergo a tooth and groove processing as a drawing process by a concave-convex cylinder. 241. Thus, the extensibility is displayed in the longitudinal direction of the tape-like laminated material 33T and the inner layer material 31 so that the elasticity of the continuous elements of the elastic member 3S is not inhibited. Tooth and groove processing does not affect the elasticity of the continuous elements of the 3S elastic member. As a result of conducting this tooth and groove processing, concave-convex elements (the concave is groove 34) are printed on the surfaces of the tape-like laminated materials mentioned above 33T in the lateral direction. The groove intervals 34 are adjusted depending on the thickness of the non-woven fabric of the first laminated material 1S and, for example, adjusted at intervals according to the case of the aforementioned pull diaper 10C. In addition, in the aforementioned stretch processing, the processing method is not limited to tooth and groove processing as long as it is a method of creating 33T tape-type laminated materials and extensible inner layer material 31.
[0115] In the fourth aspect mentioned above, effects similar to those of the first aspect mentioned above can be obtained. In addition, since the extensibility is exhibited in the 33T tape-type laminated materials (the outer layer materials 33) and the inner layer material 31, the elasticity can be printed in the direction surrounding the waist of an outer cover 11 (see figure 7 mentioned above) of the pulling diaper. Additionally, collections are easily formed by the formation of grooves 34 in the 33T tape-type laminated materials.
[0116] In the following, the fifth aspect of the production method will be explained below, with reference to the schematic perspective view of figure 17. The fifth aspect is another production method for producing the aforementioned pull diaper 10 (10A).
[0117] As illustrated in figure 17, in the fifth aspect, a first laminated material 1S is fed in the state of being divided in advance into a first laminated material 1SA to form a front 21 of an outer cover 1 and a first laminated material 1SB for form a rear part 23. Similarly, a second laminated material 2S is fed in the state of being divided into a second laminated material 2SA to form the front 21 and a front 21 to form the rear 23. Additionally, the first laminated materials mentioned above 1SA and S1B are respectively divided into several pieces by an outer layer material cutter 211 to thereby supply laminated materials such as tape 33TA and 33TB. In addition, the tape laminated materials 33TA and 33TA, and the tape laminated materials 33TB and 33TB are respectively spaced at predetermined intervals by a 213 spacing device. The widths of the tape laminated materials 33TA and 33TB (the first split laminated materials 1SA and 1SB) are similar to the width of the outer layer material 33 of the above-mentioned pull diaper 10A and the intervals therein are also similar to the intervals of the outer layer materials 33 of the above-mentioned pull diaper 10A.
[0118] Subsequent steps are similar to the first aspect mentioned above except that a step of cutting the continuous outer cover element 11S using an outer cover cutter is not conducted.
[0119] In the fifth aspect mentioned above, effects similar to those of the first aspect mentioned above can be obtained. In addition, since the first laminated material 1S is fed in the state of being divided into first laminated materials 1SA and 1SB, and the second laminated material 2S is fed in the state of being divided into second laminated materials 2SA and 2SB, it is not necessary to install an external cover cutter. Therefore, production facilities can be reduced, and the cost of production can be reduced.
[0120] The method comprising feeding the first laminated material 1SA and first laminated material 1SB in the split state as in the fifth aspect of the production method can be applied to the second to fourth aspects mentioned above. In any case, the subsequent steps are similar to the second to fourth aspects mentioned above, respectively, except for the step of cutting the continuous outer covering element 11S using an outer covering cutter that is not conducted.
[0121] In the following, a preferred embodiment (the second embodiment) of the method of producing a pull diaper according to the present invention will be explained below, with reference to the schematic perspective view of figure 18. The second embodiment is an example in which the production method of the present invention is applied to a conventional pull diaper method and production having leg holes and is a production method of the pull diaper mentioned above 100.
[0122] As illustrated in figure 18, a first laminated material 1S is fed from the upper side and a second laminated material 2S is fed from the lower side, and continuous elements of the elastic member 3S that are about to become elastic elements 35 they are simultaneously fed into the space between the first laminated material 1S and the second laminated material 2S. The first laminated material 1S forms the outer layer materials 33, and the second laminated material 2S forms an inner layer material 31. For that first laminated material 1S (outer layer materials 33), the second laminated material 2S (layer material internal 31) and continuous elements of elastic member 3S (elastic elements 35), materials similar to those respectively explained in the first example of the pull diaper are used.
[0123] First, the first laminated material 1S is divided into several pieces by an outer layer material cutter 211 to form 33T tape-type laminated materials. Next, the 33T and 33T tape-type laminated materials are spaced at predetermined intervals d1 by a spacing device similar (not shown) to the first aspect mentioned above of the first embodiment. The width of the 33T tape-type laminate material (the first 1S split laminate material) is formed in a width similar to that of the outer layer material 33 in the pull diaper mentioned above 10A and the intervals during spacing are also formed at intervals similar to those of the outer layer materials 33 of the aforementioned pull diaper 10A.
[0124] Additionally, several pieces of continuous elements of elastic member 3S are prepared in parallel, and fed into the space between the second laminated material 2S and the respective 33T spaced tape-like materials in the state in which the continuous elements of the member respective elastic 3S are elongated, and in the state in which an adhesive (not shown) fed by a similar adhesive coating apparatus (not shown) as explained in the first aspect mentioned above is applied. At that time, it is preferable that the 33T tape-laminated materials and the continuous elements of the elastic member 3S are fed so that the center of the lateral direction of the continuous element of the elastic member 3S corresponds to the center of the lateral direction of the tape-type laminated material mentioned above. 33T. For example, a thermal melting gun used as the adhesive coating apparatus mentioned above (not shown) and a thermal melting adhesive is used as the adhesive in that case.
[0125] Thus, the second laminated material 2S, the continuous elements of the elastic member 3S and the laminated materials like ribbon 33T are passed between the narrowing cylinders 217 and 218. Additionally, the second laminated material 2S and the rolled materials like ribbon 33T they are adhered through the continuous elements of the elastic member 3S by the thermal melting adhesive attached to the continuous elements of the elastic member 3S by the pressure between the cylinders, thereby providing a continuous element of outer layer 11S which must be an external cover 11.
[0126] Subsequently, a step of cutting the elastic elements, which disables the display of the elastic function of the continuous elements of elastic member 3S in the area where an absorbent body 40 is to be fixed in the next step, is conducted by a cutting cylinder 219. The method for cutting is similar to the first aspect mentioned above.
[0127] Next, in a manner similar to the first aspect mentioned above, the absorbent body 40, which is obtained by cutting a continuous material from the absorbent body 40S which is fed from an absorbent body forming part 4, is arranged in predetermined positions on the front 21 and rear 23 of the continuous element of the outer cover 11S. Subsequently, both ends of the side direction of the continuous element of the outer cover 11S are folded backwards so as to cover both end parts of the longitudinal direction of the absorbent body 40, and the absorbent body 40 is fixed to the folded back parts.
[0128] Next, leg holes 110 are drilled in the parts of both the side of the absorbent body 40 attached to the continuous element of the outer cover 11S.
[0129] Next, the longitudinal direction of the absorbent body 40 is folded in two and the front part 21 of the outer cover continuous element 11S and the rear part 23 of the outer cover continuous element 11S are overlapped by the orientation of the second laminated material 2S to turn inward, and the steps in and after the side sealing step for joining the front 21 and the rear 23 at predetermined intervals in the lateral direction are conducted to thereby complete the pull diaper 100.
[0130] In the second modality mentioned above of the production method, since single layer regions formed of inner layer material 31 are formed in a part of the outer cover 11 in a similar way to the first aspect mentioned above, the air permeability in the area single layer is greatly increased, and in this way, the pull diaper 100 in which the humidity is significantly reduced can be provided.
[0131] Additionally, since the amount of use of outer layer 33 materials can be reduced, a product considered ecological can be produced in a disposable pull diaper. In addition, it is seen that the amount of use of outer layer materials 33 can be reduced, the cost of production can be reduced.
[0132] As explained above, according to the pull garment and the pull garment production method of the present invention, the air permeability of the pull garments 10 and 100 can be greatly improved since the inner layer material 31 forms single layer areas in the parts without the outer layer materials 33 by arranging the outer layer materials at intervals in the direction of the length.
[0133] In the production method mentioned above, a production method in which 33T tape-type laminated materials are adhered to the second 2S laminated material in the addendum positions with greater precision is expected. Such a production method includes a pull garment production method of the present invention as mentioned below. Hereinafter, the method of production will be explained as a method of producing a pull-up diaper.
[0134] The first aspect of a preferred embodiment (the first embodiment) of the production method of a pull diaper of the present invention will be explained below, with reference from figure 19 to figure 23. This first aspect is a method of producing the diaper of drawing mentioned above 10. For points that are not specifically explained in other aspects mentioned below, the explanations described in detail in the first aspect are properly applied.
[0135] Figure 21 is a drawing illustrating plan views of the main parts in figure 20, where figure 21 (1) is a plan view of the main part of the first laminated material 1S and the second laminated material 2S to be arranged at the rear 23, which is seen from the top side and figure 21 (2) is a plan view of the main part of the first laminated material 1S and the second laminated material 2S to be arranged in the front 21 which is on a lower side than a first lower side separation cylinder 253, which is seen from the upper side. Through figure 21, the disposition relation between the second laminated material 2S and the tape laminated materials 33T and the disposition relationship between the laminated materials tape type 33T and the continuous element of the elastic member 3S are clarified. The type of tape refers to a state of a long, narrow strip type sheet and cut refers to the division of the laminated material several times in the lateral direction to give the shape of several pieces of tape. In the present invention, the laminated material is cut along the feed direction (the direction of the arrow A1 mentioned below) to thereby be divided into several pieces in the lateral direction of the laminated material.
[0136] As illustrated in figure 19 to figure 21, the first laminated material 1S is fed in the direction of arrow A1. This first 1S laminate material constitutes outer layer 33 materials. This first 1S laminate material is cut by an outer layer material cutter 211 and divided into several pieces to form narrow ribbon type 33T laminate materials (outer layer materials 33). For example, the respective 33T tape-type laminated materials are cut to equal widths (see figure 22 for specifics).
[0137] Additionally, the respective 33T tape-type laminated materials are fed into the space between a first top-side separation cylinder 251 and a first bottom-side separation cylinder 253 in the state in which positions in the lateral direction of the type laminate materials respective 33T tape while cutting are maintained. The various pieces of 33T tape-type laminated materials fed into the cylinder space are selected alternately one by one and wound around the first upper side separation cylinder 251 and the first lower side separation cylinder 253 to be separated in different directions ( for example, top direction and bottom direction). Specifically, the various parts of the 33T tape-laminated materials are alternately separated one by one in tape-laminated materials for the front and back sides (see figure 23 for specifics). The different directions mentioned above refer to a direction that departs from the first laminated material 1S on the side of the first surface which is one of the two surfaces possessed by the first laminated material 1S and a direction that sticks from the first laminated material 1S on the side of the second surface that is opposite the first surface, with respect to the first laminated material 1S fed to the separation position. In other words, the different directions can be two directions that move away from both surfaces of the first 1S laminate material in the direction of each opposite direction through the first 1S laminate material, and the directions are not necessarily directly opposite directions. Therefore, the directions are not limited to the aforementioned upper and lower directions, and can also be two different directions in a plane that is orthogonal to the respective geometrical axes of rotation of the first upper side separation cylinder 251 and first separation cylinder. lower side 253.a In addition, the directions of disposition of the respective axes of rotation of the first upper side separation cylinder 251 and first lower side separation cylinder 253 can have an angle such as 90 with respect to the horizontal direction. In this case, the upper and lower sides change to the right and left sides, but in this modality they are referred to as the upper side and the lower side for convenience purposes. In the present embodiment, the different directions refer to the directions that follow for the respective cylinders of the first upper-side separation cylinder 251 and the first lower-side separation cylinder 253.
[0138] When the 33T tape-type laminated materials to the rear side, which were wound around the first top-side separation cylinder 251 and were separated in the direction of the upper direction, are rolled around a second top-side separation cylinder 252, the second laminated material 2S is fed, from the feed in the opposite direction to the feed direction of the first laminated material 1S (the direction of an arrow A), into the space between the first separating cylinder on the upper side 251 and the second upper side separation cylinder 252 so as to wrap directly around the second upper side separation cylinder 252. This second laminated material 2S constitutes the inner layer material 31. Additionally, several pieces of continuous members of elastic member 3S are prepared in parallel and fed together with the second laminated material 2S in the state in which the continuous elements of the respective elastic member are extended, en the state in which an adhesive (not shown) fed by an adhesive coating apparatus 215 is applied. At that moment, for example, they are fed in such a way that the center of the lateral direction of the continuous elements of elastic member 3S is positioned in the center of the lateral direction of the 33T tape-type laminated material. The continuous elements of the elastic member 3S constitute elastic elements 35. For example, a thermal melt gun is used as the adhesive coating apparatus mentioned above 215, and a thermal melt adhesive is used as the adhesive in that case.
[0139] Thus, a pressure is applied between the first upper side separation cylinder 251 and the second upper side separation cylinder 252, and the 33T tape-type laminated materials are added to the second 2S laminated material through the continuous member elements elastic 3S by the adhesive applied to the continuous elements of the elastic member 3S. At that time, the 33T tape-laminated materials are transported while rolled around the cylinder surface of the first top-side separation roller 251 without sliding, and thus the positions in the lateral direction of the respective 33T tape-laminated materials during the cutting are maintained. In this state, the 33T tape-type laminated materials are adhered to the second laminated material 2S without departing from the first upper-side separation cylinder 251. As a result, a continuous element of the outer cover 11S which must be the rear 23 formed from of the second laminated material 2S to which the 33T tape-type laminated materials are adhered through the continuous elements of elastic member 3S, is constituted. In addition, both sides of the outer cover continuous element 11S to the rear 23 are inverted in the state in which the outer cover continuous element 11S is wound around the second upper side preparation cylinder 252, and the continuous cover element external 11S is fed in the direction of an A2 arrow.
[0140] On the other hand, when the 33T tape-type laminated materials for the front side, which were wound in the first lower side separation cylinder 253 and were separated in the direction of the lower direction, wound around a second separation roller, bottom side 254, the second laminated material 2S is fed, from the direction opposite to the feed direction of the first laminated material 1S (the direction of an arrow A1), into the space between the first lower side separation cylinder 253 and the second lower-side separation cylinder 254 so as to wrap directly around the second lower-side separation cylinder 254. Additionally, several pieces of continuous elements of elastic member 3S are prepared in parallel, and fed together with the second laminated material 2S in the state in which the respective elastic member continuous elements are extended, and in the state in which an adhesive (not shown) which is fed by an apparatus and adhesive coating 215 is applied. At that time, it is preferable that they are fed so that the center of the lateral direction of the continuous member of the elastic member 3S is positioned in the center of the lateral direction of the tape-like laminated material mentioned above 33T. For example, a thermal melt gun is used as the adhesive coating apparatus mentioned above 215, and a thermal melt adhesive is used as the adhesive in that case.
[0141] In the adhesive coating apparatus 215, although individual thermal melting guns are used for the respective continuous members of elastic member 3S, it is also preferable to use an integrated type melting gun (not shown) having several nozzles from of which an adhesive is ejected to the positions corresponding to the continuous elastic elements 3S.
[0142] Additionally, the adhesive can be applied to the surface of the second laminated material 2S in the positions where the continuous elements of the elastic member 3S are arranged instead of being applied to the continuous elements of the elastic member 3S. The application can be continuous or intermittent.
[0143] Additionally, the first and second top-side separation cylinders 251 and 252, and the first and second bottom-side separation cylinders 253 and 254 are rotating cylinders, and the first top-side separation cylinder 251 and the first bottom side separation cylinder 253 are rotatable by a rotary drive device which is not shown. Examples of rotary drive devices may include an engine. In addition, it is preferable that the rotating cylinders each have a surface with a high frictional force such as a rough surface or rubber on the circumferential surface of the cylinder so that the sheet is fed at a circumferential speed. In addition, the second top-side separation cylinder 252 and the second bottom-side separation cylinder 254 can be cylinders that are rotated by a rotary drive device. In that case, the rotating drive device is rotated at a circumferential speed equivalent to the circumferential speeds of the first upper-side separation cylinder 251 and the first lower-side separation cylinder 253.
[0144] Thus, a pressure is applied between the first lower-side separation cylinder 253 and a second lower-side separation cylinder 254, and the 33T tape-type laminated materials are added to the second 2S laminated material through the continuous members of the member elastic 3S by the adhesive applied to the continuous elements of the elastic member 3S. At that time, the 33T tape-type laminated materials are carried by winding around the bearing surfaces of the first lower-side separation cylinder 253 without sliding, and thus are adhered to the second laminated material 2S in the state in which the positions in the lateral direction of the respective 33T tape-type laminated materials during cutting are maintained. As a result, a continuous outer covering element 11S which must be the front part 21 formed from the second laminated material 2S to which the tape-like laminated materials 33T are adhered through the continuous elements of the elastic member 3S, is formed. In addition, both sides of the outer cover continuous element 11S to the front 21 are inverted in the state in which the outer cover continuous element 11S is wound around the second lower side separating cylinder 254, and the continuous cover element external 11S is fed in the direction of an A3 arrow.
[0145] Since 33T tape-laminated materials are alternately separated in the top and bottom directions, the position ratios of the respective provisions of the 33T-tape laminated materials separated in the top direction and the 33T-tape laminated materials separated in the second direction 2S laminated material are different. Therefore, in the case where the positions of the 33T tape-laminated materials arranged in the second 2S laminate material to the rear side and the positions of the 33T-tape laminated materials arranged in the second 2S laminated material to the front side are combined on the rear and front side , the feed positions of the 33T tape laminated materials to be disposed in the second 2S laminated material for the rear side and the feed positions of the 33T tape laminated materials to be disposed in the second 2S laminated material for the front side are different. Therefore, by adjusting at least one of the feed positions of the second laminated materials 2S, for example, by displacing one of the second laminated materials 2S in the lateral direction, the position ratio of the 33T tape-type laminated materials arranged in the second laminated material 2S for the rear side and the position ratio of the 33T tape-type laminated materials which are arranged in the second laminated material 2S for the front side can be shaped.
[0146] Additionally, in the respective second laminated materials 2S for the rear and front side to which the 33T tape-laminated materials are adhered, the positions of the 33T tape-laminated materials arranged in the lateral directions of the respective second 2S laminated materials may differ in case of application to a diaper.
[0147] As explained above, in order for 33T tape-type laminated materials to be adhered to the second 2S laminated material through the continuous elements of the 3S elastic member to which the adhesive is applied, it is necessary that the second 2S laminated material, the elements stretches of the elastic member 3S and the 33T tape-type laminated materials are rolled from the direction table in that order, and fed into the space between the first and second top-side separation cylinders 251 and 252 and the space between the first and second cylinders 253 and 254 underside separators. By feeding in this way, the attachment of the adhesive applied to the continuous elements of the elastic member 3S to the rolling surfaces can be avoided.
[0148] Next, the positions of the respective external cover continuous elements 11S on the front 21 and rear 23 are adjusted to provide a predetermined interval D. In this position adjustment step, for example, the position of the continuous cover element outer 11S for front 21 is adjusted. Specifically, the feed direction of the outer cover continuous element 11S to the front 21 is set to the direction (direction of arrow A4) that is parallel with the feed direction (the direction of arrow A2) of the cover continuous element outer 11S for the rear 23, and the surface on the side of the second laminated material 2S of the outer covering element 11S for the front 21 and the surface on the side of the second laminated material 2S of the outer covering element 11S for the part rear 23 are adjusted to be in the same plane direction (for example, the top surface) and at the same height.
[0149] First, both surfaces of the outer cover continuous element 11S for the front 21 are inverted by an inversion cylinder 260 whose PE bearing axis arranged in the right angles to the feed direction (the direction of a arrow A3) of the continuous outer cover element 11S of the front 21. By this invention the feed direction is also reversed. Subsequently, in order that the feed direction becomes the direction of arrow B which is changed to the lateral direction (preferably the 90 direction) with respect to the inverted feed direction, both the surface of the continuous outer cover element 11S to the front part 21 is inverted by a first cylinder 261 whose cylinder axis is arranged at a predetermined angle (for example, 30 to 60, preferably 45) with respect to the inverted feed direction mentioned above and the feed direction is adjusted to the direction of an arrow B. Subsequently, the feed direction of the continuous outer cover element 11S to the front 21 is changed from the horizontal direction to the vertical direction of an arrow C by a second cylinder 262. Subsequently, the feed direction from the continuous outer cover element 11S to the front 21 is changed from the vertical to the horizontal direction by a third cylinder o 263. Next, both surfaces of the continuous outer cover elements 11S to the front 21 are inverted by a fourth cylinder 264 whose geometric bearing axis is arranged at a predetermined angle (for example, 30 to 60, preferably 45) with respect to the feed direction of the outer cover continuous element 11S to the front 21, to thereby direct the surface on the side of the second laminated material 2S of the outer cover continuous element 11S to the front 21 and the surface in side of the second laminated material 2S of the continuous cover element 11S towards the rear 23 in the direction of the same plane direction (the upper surface), and the surfaces are positioned at the same height, and the feed direction is changed to the direction side (for example, the direction of 90 is preferred) to thereby provide the feed direction in the direction of an A4 arrow, which is parallel to the continuous element external cover 11S for rear 23.
[0150] In the first and third cylinders 261 and 263, the surfaces on the side of the second laminated material 2S of the respective continuous outer cover elements 11S on the front 21 and the rear 23 are adjusted to be at the same height by adjusting the gap of the continuous outer cover elements 11S on the front pate 21 and rear 23 for a predetermined interval D, and the adjustment of the interval of the second and four cylinders 262 and 264 considering the cylinder diameters of the first and third cylinders 261 and 263. Additionally, since the first and fourth cylinders 261 and 264 are called rotation cylinders, they do not rotate, and have cylinder surfaces on which the sheet slides. The inversion cylinder 260, the second cylinder 262 and the third cylinder 263 are rotary cylinders and can also be cylinders which are driven by rotation by a rotating drive device which is not shown. Examples of rotary drive devices may include a motor. In addition, it is preferable that the rotating cylinders each have a surface with a large frictional force such as a rough surface or rubber on the circumferential surface of the cylinder so that the sheet is fed at its circumferential speed. Additionally, it is preferable that the circumferential speed of each cylinder is a constant speed so that the sheet is not extremely pulled or slack.
[0151] The cylinder constitution of the inverted cylinder mentioned above 260 and first to fourth cylinders 261 to 264 is an example, and the other cylinder constitution can also be adopted since the surfaces on the side of the second laminated material 2S of the continuous element of respective external cover 11S for front 21 and rear 23 can be directed in the same plane direction and positioned at the same height, in order to obtain the feed direction in the direction that the respective external cover continuous elements 11S at the front 21 and the rear 23 are in parallel.
[0152] In addition to the method mentioned above only by combining cylinders, the following is exemplified as a method of adjusting the positions of the respective continuous outer cover elements 11S to be displayed on the front 21 and rear 23 in the predetermined range D: both the surfaces of the second laminated material 2S to which the tape-like laminated materials 33T on the front side are attached are inverted, and the second sheet 2S arranged on the rear side and the second sheet 2S arranged on the front side are adjusted using a spacing device (not shown) to be in the state in which 33T tape-laminated materials are arranged on the surface side (or rear surface side) and to be fed parallel to each other in a flat view, similar to the production method of the pull diaper 10 as explained by the figures 10 to 13 mentioned above. In addition, the height of the second laminated material 2S arranged on the rear side and the height of the second laminated material 2S arranged on the front side can be adjusted to the same height by using cylinders (not shown).
[0153] Subsequently, in ways similar to the steps as explained in the example mentioned above, of the production method, the steps in and after the lamination step of an absorbent body 40 in order to create a bridge between the second 2S laminated materials of the respective continuous outer cover elements 11S on the front 21 and rear 23 are conducted. In addition, prior to laminating the absorbent body 40, a step of cutting the elastic elements that deactivates the expression of the elastic function of the continuous elements of the elastic member 3S in the part of the second laminated material 2S to which the absorbent body 40 is attached can also be conducted , similarly to what was explained in the example of the production method mentioned above.
[0154] As a result, a pull diaper 10 (see figure 1 mentioned above) is completed and, thus, the constitution as explained in the example of the pull diaper mentioned above can be obtained.
[0155] It is preferable that 33T tape-type laminated materials have a width that is approximately similar to or greater than the width of the 3S elastic member continuous elements. For example, it is preferable to adjust the width of 33T tape-type laminated materials to 0.5 mm to 60 mm, and it is preferable to adjust the fixing intervals of 33T tape-type materials to 1 mm to 40 mm. Preferably and in addition, the width of the 33T tape-type laminated materials is adjusted to 3 mm to 30 mm, and the attachment intervals of the 33T tape-type materials are adjusted to 3 mm to 30 mm. Preferably still, the width of the 33T tape-type laminated materials is adjusted to 5 mm to 10 mm, and the fixing intervals of the 33T tape-type materials are adjusted to 5 mm to 10 mm.
[0156] Additionally, since the side steering end parts (the end parts in the diaper length direction) of 33T tape-type laminated materials are free ends, when the stretch load of the 3S elastic member continuous elements is released , 33T tape-type laminated materials contract due to the contraction of the elastic elements to form ornaments (not shown). Therefore, there is an action in which the pleasant appearance can be created as a whole in the diaper. In addition, the fixing position of the 33T tape-laminated materials to the second 2S laminated material is not limited to the central part of the 33T-tape laminated materials in the lateral direction (Y direction), and can be deviated to any lateral direction. That is, in the lateral direction of 33T tape-type laminated materials, the distance between the fixing position to the second laminated material 2S and one edge can be long and the distance to the other edge can be short. By changing the distances from the attachment position to the edges in this way, the ornaments are easily formed at the longest distance. Additionally, the application of 3S elastic member continuous elements to 33T tape-type laminated materials by orienting the attachment positions of the 3S elastic member continuous elements against 33T tape-type laminated materials is made easier by the use of the production method of the present invention. which provides greater accuracy of the feeding positions of 33T tape-type laminated materials.
[0157] In the production method of the first aspect mentioned above, the continuous outer cover element 11S for the front 21 can be created in the step of preparing the continuous outer cover element 11S for the rear 23, and the continuous element of external cover 11S for the rear 23 can be created in the step of preparing the continuous external cover element 11S for the front 21.
[0158] In the method of producing a first-diaper pull diaper mentioned above, single layer areas formed from the inner layer material 31 are formed while maintaining the elasticity similar to that of a conventional pull and hold diaper of the ability to fit to the body and body mobility, by rolling several pieces of 33T tape-type laminated materials formed by cutting the first laminated material 1S, with the second laminated material 2S, in the state in which the positions in the lateral direction of the laminated materials 33T tape type during cutting are maintained respectively. Thus, air permeability is increased in the single layer area, and in this way, the pull diaper 10 in which the humidity is significantly reduced can be provided.
[0159] Additionally, since the amount of use of the eternal layer 33 materials can be reduced, an ecological product can be produced in a disposable pull diaper. Additionally, since the amount of use of outer layer materials can be reduced, the cost of production can be reduced. In addition, the softness of the outer cover 11 is improved, and the movement during use becomes smooth and the comfort of use is improved, with areas of single layer.
[0160] Additionally, since the 33T tape-type laminated materials for the front and rear side are laminated and attached to the second 2S laminated material while they are in the state of being rolled into cylinders, thereby maintaining their respective positions in the lateral direction. during cutting, 33T tape-type laminated materials can be placed on the second 2S laminated material with high precision. It is preferable to suppress the lack of alignment in the lateral direction of the 33T tape-laminated materials in a width band of them or less, and, for example, in the case where the width of the 33T tape-laminated material is 3 mm, the lack of alignment can be suppressed to 2 mm or less in the lateral direction. Although the details are mentioned below, in doing so, it becomes easy to arrange and adhere the various pieces of continuous elements of elastic member 3S in a piece of laminated material type 33T tape and, thus, it is possible to easily change the intensity of elasticity across the locations in the length direction, and a pull-on garment having excellent fit can be provided.
[0161] Additionally, since 33T type laminated materials for the front and rear side are laminated and fixed to the second 2S laminated materials in the state in which the respective positions in the lateral direction during cutting are maintained, and in the state in which the tape-like laminated materials are wound around the first top-side separation cylinder 251 and the first bottom-side separation cylinder 253, the tension of the 33T tape-like materials can be stabilized. Specifically, since the 33T tape-laminated materials can be adhered to the second 2S laminated materials in the state in which the 33T-tape laminated materials have constant tension, the entire outer cover of the pull diaper 10 is placed in a state of homogeneous tension , and in this way, usability is improved.
[0162] Additionally, the 33T tape-type laminated materials do not oscillate in the lateral direction during transport, the accuracy of the fixing positions of the 33T tape-type materials on the second 2S laminate material can be further improved.
[0163] Additionally, since the spacing interval of the 33T tape-laminated materials is equal to the width of the 33T-tape laminated material, the 33T-tape laminated materials are laminated and fixed to the second 2S laminated material at equal intervals. Thus, when the pull diaper 10 is created, the 33T tape-type laminated materials adhered through the continuous members of elastic member 3S are uniformly and equally arranged over the entire surface of the outer cover 10 of the trousers, and thus the diaper of pull 10 with proper use can be provided. Additionally, by adjusting the fixing intervals of 33T tape-type laminated materials at equal intervals, an action in which the tension applied to the body by the contraction of continuous elements of elastic member 3S (elastic elements 35) is equally dispersed can be obtained , and an effect in which the aesthetic impression in appearance (aesthetic impression provided by regularity) is also improved.
[0164] The feed direction of one of the continuous outer cover elements 11S is transferred in parallel by two cylinders (the first and fourth cylinders 261 and 264) whose bearing axes are arranged at a predetermined angle θ (0 <θ < 90) with respect to the direction of arrow A1, and the height of the continuous outer cover element 11S can be adjusted by two cylinders (the second and third cylinders 262 and 263) whose bearing axes are arranged in parallel with respect to the feed direction sheet (for example, the arrow direction A1). Thus, the range of the respective outer cover continuous elements 11S of the front 21 and rear 23 can be easily adjusted to the predetermined range D, and in addition, the surfaces on the side of the second laminated materials 2S of the respective outer cover elements 11S on the front 21 and the rear 23 can be easily positioned at the same height. As a result, when the absorbent body 40 is laminated to the respective external cover continuous elements 11S on the front 21 and rear 23, it is not necessary to combine the heights of the respective external cover continuous elements 11S, and thus the cleaning step of the absorbent body 40 becomes easy.
[0165] Additionally, depending on the constitution of the production equipment and the space for the disposal of the production equipment, it is difficult in some cases to feed the respective continuous elements of elastic member 3S and the respective second laminated materials 2S to the front and side rear from the same direction to the spaces of the pair of first and second separation cylinders on the top side 251 and 252, and the spaces of the first and second separation cylinders on the side 253 and 254, respectively. In such cases, the feed direction of the continuous elements of the elastic member 3S can be reversed, or the feed directions of both continuous elements of the elastic member 3S and second laminated materials 2S can be reversed. The production methods in these constitutions will be explained below.
[0166] Next, the second aspect of the first modality will be explained below, with reference to figure 24. The second aspect is a production method of the diaper mentioned above 10, which is a production method in which the continuous elements of the elastic member 3S are fed from directions or those of the first aspect.
[0167] As illustrated in figure 24, similarly to the first aspect mentioned above, a first 1S laminated material (outer layer materials 33) is fed in the direction of an arrow A1, cut several times in the lateral direction by a material cutter outer layer 211, and divided into several parts of 33T narrow ribbon laminated materials (outer layer materials 33). In addition, the respective ribbon-like laminated materials 33T are fed into the space between the first upper-side separation cylinder 251 and a first lower-side separation cylinder 253 in the state in which the positions in the lateral direction during cutting are maintained. Then, the tape-laminated materials 33T are wound around the first top-side separation roller 251 and the first bottom-side separation cylinder 253 in an alternating manner, so that the tape-type laminated materials 33T are separated in two different directions. (for example, the top direction and the bottom direction).
[0168] Additionally, similarly to the first aspect mentioned above, a second 2S laminated material (an inner layer material 31) is fed, from the direction opposite to the feed direction (the direction of arrow A1) of the first laminated material 1S, for the space between the first top-side separation cylinder 251 and the second top-side separation cylinder 252, so that the second laminated material 2S winds directly around the second top-side separation cylinder 252. Additionally, several pieces of continuous elements of elastic member 3S (elastic elements 35) are fed in parallel together with the second laminated material 2S, in the state in which the respective continuous members of elastic member 3S are extended, and in the state in which an adhesive ( (not shown) powered by an adhesive liner 215 is applied.
[0169] Thus, a pressure is applied between the first upper-side separation cylinder 251 and a second upper-side separation cylinder 252, and thus a continuous outer cover element 11S that must be a rear 23 that it is formed from the second laminated material 2S to which the laminated materials type tape 33T are added through the continuous elements of elastic member 3S, it is constituted. In addition, both sides of the outer cover continuous element 11S to the rear 23 are inverted in the state in which the outer cover continuous element 11S is wound around the second upper side separation cylinder 252, and the continuous cover element external 11S is fed in the direction of an A2 arrow.
[0170] On the other hand, the 33T tape-type laminated materials for the front side are wound around the first lower side separation cylinder 253 and are separated in the lower direction, and additionally wind around the second lower side separation cylinder 254 and are transported. A guide roller 255, which is arranged at the bottom of the second lower-side separation cylinder 254, feeds the second laminated material 2S to the front side from the direction put to the feed direction of the first laminated material 1S, and the second laminated material 2S winds directly around the guide cylinder 255 from the bottom side of the guide cylinder and is fed into the space between the guide cylinder 255 and the second lower-side separation cylinder 254. Additionally, in the space between the guide cylinder 255 and the second lower-side separation cylinder 254, several pieces of continuous elements of elastic member 3S, which must be the elastic elements 35 for the front side, are fed in parallel in the second laminated material 2S wrapped around the guide cylinder 255 , from the same direction to the feed direction (direction of arrow A1) of the first laminated material 1S. The respective continuous elements of elastic member 3S are fed in the state in which the respective elements are extended and in the state in which an adhesive (not shown) fed from the adhesive liner 215 is applied, and the 33T tape-type laminated materials transported while winding around the second lower side separating cylinder 254 and the second laminated material 2S are adhered through these continuous elements of elastic member 3S. The aforementioned guide cylinder 255 is preferably a rotating cylinder which is rotated by a rotating drive device similar (not shown) to the one mentioned above. In that case, it is preferable that the circumferential speed of the guide cylinder 255 corresponds to the circumferential speed of the second lower-side separation cylinder 254. Additionally, it is preferable that the guide cylinder 255 has a surface with a large frictional force such as a rough surface or rubber on the circumferential surface of the cylinder so that the sheet does not slide on the circumferential surface of the cylinder.
[0171] Thus, a pressure is applied between the second lower side separation cylinder 254 and the guide cylinder 255, and the 33T tape-type laminated materials are adhered to the second 2S laminated material through the continuous elements of the elastic member 3S by the applied adhesive. to the continuous elements of the elastic member 3S. At that time, the 33T tape-type laminated materials are transported by winding around the bearing surfaces of the first lower-side separation cylinder 253 and the second lower-side separation cylinder 254 without sliding, and thus are adhered to the second 2S laminated material in the state in which positions in the lateral direction during cutting are maintained. In addition, the 33T tape-type laminated materials are adhered to the second 2S laminated material without departing from the respective cylinder surfaces of the first lower-side separation cylinder 253 and second lower-side separation cylinder 254. As a result, a continuous element of external cover 11S which must be the rear part 21 made from the second laminated material 2S to which the laminated materials type tape 33T are adhered through the continuous elements of elastic member 3S is constituted. In addition, the continuous outer cover element 11S for the front 21 is fed in the direction of an arrow A5 from the space between the second lower-side separation cylinder 254 and the guide cylinder 255.
[0172] As explained above, in order for the 33T tape-type laminated materials to be adhered to the second 2S laminated material through the continuous 3S elastic member elements to which the adhesive is applied, it is necessary that the second 2S laminated material, the elements stretches of elastic member 3S and tape-like laminated materials 33T are rolled from the same direction in that order, and fed into the space between the second lower-side separation cylinders 254 and the guide roller 255. By feeding in such a way, fixing the adhesive applied to the continuous elements of the elastic member 3S to the cylinder surfaces can be avoided.
[0173] Next, the positions of the respective continuous elements of the outer cover 11S on the front 21 and rear 23 are adjusted to provide a predetermined interval D. In this position adjustment step, the feed direction of the continuous element of the external cover 11S for the front 21 is adjusted to the direction (the direction of the arrow A4) that is parallel to the feed direction (the direction of the arrow A2) of the continuous outer cover element 11S to the rear 23, and the surface on the side of the second laminated material 2S of the outer cover continuous element 11S for the front 21 and the surface on the side of the second laminated material 2S of the outer cover continuous element 11S for the rear 23 are adjusted to be in the same plane direction (for example, the top surface) and at the same height.
[0174] First, both surfaces of the outer cover continuous element 11S to the front 21 are inverted by a first cylinder 261 whose bearing axis is arranged at a predetermined angle (for example, 30 to 60, preferably 45) with respect to the feed direction (the direction of an arrow A5) of the continuous outer cover element 11S to the front 21, and the feed direction is changed to the direction of an arrow B1. Subsequently, the feed direction of the outer cover continuous element 11S to the front 21 is changed from the horizontal direction to the vertical direction (the direction of an arrow C) by a second cylinder 262. Subsequently, the feed direction of the continuous element outer cover 11S for the front 21 is changed from the vertical direction to the horizontal direction (the direction of an arrow B2) by a third cylinder 263. Next, both surfaces of the continuous outer cover element 11S to the front 21 are inverted by a fourth cylinder 264 whose bearing axis is arranged at a predetermined angle (for example, from 30 to 60, preferably 45) with respect to the feed direction of the continuous outer cover element 11S to the front 21 to, from there way, direct the surface on the side of the second laminated material 2S of the continuous outer covering element 11S to the front 21 and the surface on the side of the second laminated material 2S of the outer cover continuous element 11S to the rear 23 in the direction of the same plane direction (top surface) and positioned at the same height, and the feed direction becomes the feed direction (the direction of an arrow A4) which is in parallel with the external outer cover element 11S for the rear 23.
[0175] Therefore, by the first and third cylinders 261 and 263, the surfaces on the side of the second laminated material 2S of the respective continuous outer cover elements 11S on the front 21 and rear 23 are adjusted to be at the same height by adjusting the range of the respective continuous outer cover elements 11S on the front 21 and rear 23 for a predetermined range D, and the adjustment of the range of the second and fourth cylinders 262 and 264 taking into account the cylinder diameters of the first and third cylinders 261 and 263 .
[0176] Subsequently, the production steps are similar to those in the production method as explained in the first aspect mentioned above.
[0177] In the following, the third aspect of the first aspect will be explained below, with reference to figure 25. The third aspect is a production method of the pull diaper mentioned above 10 which is a production method in which the continuous member elements elastic 3S and the second laminated material 2S are fed from directions opposite those of the first aspect.
[0178] As illustrated in figure 25, a continuous outer covering element 11S to be arranged on a rear part 23 is constituted similarly to the first aspect mentioned above, both surfaces are inverted in the state in which the continuous outer covering element 11S is wound around the second upper side separation cylinder 252, and the continuous outer cover element 11S is fed in the direction of an arrow A2.
[0179] On the other hand, tape-like laminated materials 33T to the front side are rolled around the first bottom cylinder 253 and are separated in the bottom direction, and further rolled around the second bottom side cylinder 254 and are transported. A guide roller 255 is arranged at the bottom of the second lower-side separation cylinder 254, and the second laminated material 2S to the front is fed from the direction of arrow A3 which is similar to the feed direction of the first laminated material 1S and sent into the space between the second lower-side separation cylinder 254 and the guide cylinder 255. Additionally, in the space between the guide cylinder 255 and the second lower-side separation cylinder 254, several pieces of the continuous elements of the elastic member 3S which must be the elastic elements 35 for the front side are fed in parallel in the second laminated material 2S from the same direction to the feeding direction (the direction of the arrow A1) of the first laminated material 1S. The respective 3S elastic member continuous elements are fed in the state in which the respective elements are extended and in the state in which an adhesive (not shown) fed from the adhesive coating apparatus 215 is applied to them, and the laminated materials type tape 33T transported while wrapping around the second lower side separation cylinder 254 are adhered through these continuous elements of elastic member 3S.
[0180] Thus, a pressure is applied between the second lower side separation cylinder 254 and the guide cylinder 255, and the 33T tape-type laminated materials are adhered to the second 2S laminated material through the continuous members of elastic member 3S by the applied adhesive. continuous elements of elastic member 3S. At that time, the 33T tape-type laminated materials are transported by winding around the winding surfaces of the first separation roller on the bottom side 253 without sliding, and thus are added to the second laminated material 2S in the state in which the positions in the lateral direction during cutting are maintained. In addition, the 33T tape-type laminated materials are added to the second 2S laminated material without departing from the respective bearing surfaces of the first lower-side separation cylinder 253 and the second lower-side separation cylinder 254. As a result, a continuous element of external cover 11S which must be the rear part 21 made from the second laminated material 2S to which the laminated materials type tape 33T are adhered through the continuous elements of elastic member 3S is constituted. In addition, the continuous outer cover element 11S for the front 21 is fed in the direction of an arrow A5 from the space between the second lower-side separation cylinder 254 and the guide cylinder 255.
[0181] Next, the positions of the respective continuous outer cover elements 11S in the front 21 and rear 23 are adjusted to provide a predetermined range D. This position adjustment method is similar to the second aspect mentioned above. As a result, the surface on the side of the second laminated material 2S of the outer cover element 11S to the front 21 and the surface on the side of the second laminated material 2S of the outer cover element 11S to the rear 23 are directed at the direction from the same plane direction (the top surface) and positioned at the same height, and the feed direction becomes the feed direction (the direction of an A4 arrow) which is parallel to the continuous outer cover element 11S to the rear 23 is obtained.
[0182] Subsequent production steps are similar to those in the production method as explained in the first aspect mentioned above.
[0183] Action and effect similar to the first aspect mentioned above can also be obtained in the second and third aspects. In addition, in order for the 33T tape-type laminated materials to be adhered to the second 2S laminated material through the continuous elastic member elements 3S to which the adhesive is applied, it is necessary that the second 2S laminated material, the continuous elastic member elements 3S and the 33T tape-type laminated materials are laminated from the same direction in that order, and fed into the space between the second lower-side separation cylinders 254 and the guide roller 255. By feeding in such a way, the attachment of the applied adhesive to the continuous elements of the elastic member 3S to the rolling surfaces can be avoided.
[0184] In the following, the second embodiment of the production method of the present invention will be explained below, with reference to figure 26. The second embodiment is a preferable example of a method for producing a pull diaper in which the continuous elements of the elastic member 3S are not used in the pull diaper mentioned above 10.
[0185] As illustrated in figure 26, a first laminated material 1S having elasticity (outer layer materials 33) is fed in the direction of an arrow A1 similarly to the first aspect of the first modality.
[0186] As the first laminated material 1S (the outer layer 33 materials) having elasticity, elastic sheets such as non-woven fabrics comprising elastic fibers and elastic or similar films can be used. In the case where texture and fabric-like appearance are emphasized, it is preferable that these stretchable sheets have a layer of fiber on the surface. In the case where this fiber layer is not elastic, the fiber layer is made extensible by stretching or similar processing so that the non-elastic fiber layer does not inhibit the elasticity of the elastic sheet. As the stretch processing, for example, a tooth and groove processing in which the union between the fibers is cut or the fibers are elongated in the fiber layer is exemplified, and in this way, the elasticity is displayed without inhibiting the elasticity of the sheet elastic having the fiber layer.
[0187] The entire surface area of the first 1S laminated material is subjected to tooth and groove processing as a stretch processing by a concave-convex cylinder 241 having a bearing surface on which the concave-convex part is formed. In addition, a concave-convex cylinder 242 that engages with the concave-convex cylinder 241 is arranged in the position corresponding to the concave-convex cylinder 241. As a result, grooves (omitted illustration) are printed on the first laminated material 1S in the lateral direction. Through this tooth and groove processing, the extension capacity is printed to the fiber layer in the first 1S laminated material in the longitudinal direction of the same, without inhibiting the elasticity of the elastic sheet, to thereby allow the first 1S laminated material to display elasticity. These groove intervals depend on the thickness of the non-woven fabric of the first 1S laminated material and, for example, are formed at equal intervals. Additionally, in the case where the degree of impression of elasticity is changed in each position, it is also possible to change the groove intervals. For example, in the case where the thickness of the first 1S laminated material is 0.01 mm to 0.2 mm, in an area where strong elasticity is desired, the groove intervals are adjusted to about 2 mm to 5 mm, and in an area where weak elasticity is desired, the groove intervals are adjusted to about 0.5 mm to 2. mm. The groove intervals are also changed depending on the thickness of the first 1S laminated material.
[0188] The elasticity to which the first laminated material 1S as used here refers, for example, is the elasticity that can replace the printed elasticity with the continuous elements of the elastic member mentioned above 3S. The method for processing the first 1S laminated material is not limited as long as the outer layer materials have the elasticity desired by the grooves.
[0189] As the first laminated material mentioned above 1S having elasticity, for example, (1) a sheet comprising an elastic fiber layer and an extensible fiber layer which are integrated with one or both surfaces of the elastic fiber layer, ( 2) a sheet comprising an elastic sheet-like sheet and a layer of extensible fiber which are integrated with one or both surfaces of the elastic sheet, (3) a sheet comprising an elastic sheet made of an elastic film and a layer of extensible fiber which is integrated with one or both surfaces of the elastic sheet, (4) an elastic sheet in which many elastic filaments arranged to be extensible in one direction without forming an intersection with each other are joined to an extensively substantially non-woven fabric in a non-extensible state, across their entire length.
[0190] Like the sheet (1) mentioned above, for example, (a) an elastic non-woven fabric in which a substantially non-elastic fiber layer is arranged on at least one surface of an elastic fiber layer, where both layers fibers are joined over the entire surface by thermal fusion joining of the fiber intersection points in the state in which the constituting fibers in the elastic fiber layer retain the fiber shapes, and the non-woven fabric is in the state in which a part of the constitution fibers in the non-elastic fiber layer penetrated the elastic fiber layer, and the state in which a part of the constitution fibers in the elastic fiber layer penetrated the non-elastic fiber layer, or in both states, can be exemplified . In addition, like the sheets of (1) to (3) mentioned above, (b) an elastic sheet having an elastic layer with elastic stretch capacity and a layer of substantially non-elastic fiber, where the two layers are created in a laminated sheet by lamination in the direction of its thickness and partially joined and a drawing is carried out on the laminated sheet, and the like can preferably be used. As a means of stretching and obtaining the extensible fiber layers and non-woven fabrics of the (1) to (3) mentioned above, it is preferable to conduct the above mentioned tooth and groove processing.
[0191] As the elastic non-woven fabric of (a) mentioned above, at and near the interface of the elastic fiber layer and non-elastic fiber layer, the points of intersection of the fibers constituting the elastic fiber layer and the fibers constituting the non-elastic fiber layer are joined by thermal fusion, and thus are also joined substantially across the surface. Since two layers are joined across the surface, the formation of spaces by the separation of two layers is prevented, and an elastic non-woven fabric having a multilayer structure that provides the feeling of unity as a single-layer non-woven fabric. It is formed. The state mentioned above in which the fibers constituting the elastic fiber layer retain the fiber shapes refers to a state in which most of the constituting fibers in the elastic fiber layer are not deformed into a film format, or a film structure comprising fibers, even in the case where heat, pressure or similar are applied. In addition, in the elastic fiber layer, the intersection points of the constitution fibers are joined by thermal fusion in the layer. Similarly, also in the non-elastic fiber layer, the intersection points of the constituting fibers are joined by thermal fusion in the layer.
[0192] In the case where the non-elastic fiber layers are arranged on both surfaces of the elastic fiber layer, at least one surface is in a state in which a part of the constituting fibers has penetrated the elastic fiber layer, and the state in which a part of the constituting fibers in the elastic fiber layer has penetrated at least one of the non-elastic fiber layers or in both states.
[0193] The elastic fiber layer has a property in which it can be stretched and has a property of contracting when it is released from the stretch load. Additionally, it is an aggregate of fibers having elasticity. In addition, the elastic fiber layer may be in the form of a canvas or a non-woven fabric formed of fibers having elasticity. For example, it can be a non-woven fabric formed by a blowing winding process, a winding joining process, a blowing fusion process or the like. Specifically, a fabric obtained by a blow-up winding process is preferable. As constituting fibers for the elastic fiber layer, for example, fibers obtained from basic materials such as thermoplastic elastomers and rubbers can be used. Specifically, the fibers obtained from the thermoplastic elastomers as raw materials are preferable for the elastic non-woven fabric in the modality comprising an air-permeable non-woven fabric as a basic constitution, since the melt winding using an extruder equal to that of thermoplastic resins in general it is possible, and the fibers obtained in such a way are easily joined by thermal fusion. Examples of thermoplastic elastomers may include styrene-based elastomers such as SBS, SIS, SEBS and SEPS, olefin-based elastomers, polyester-based elastomers, and polyurethane-based elastomers. They can be used for one type only or for a combination of two or more types.
[0194] The non-elastic fiber layer has extensibility, but is substantially non-elastic. The extensibility as used here may be the case where the constitution fibers themselves elongate, and the case in which the constitution fibers themselves do not elongate, but the entire fiber layer elongates due to a separation of the fibers that are united by thermal fusion at the intersection points of the fibers, a change of structure in the three-dimensional structure formed from several pieces of fibers by the union of thermal fusion of the fibers and the like, or a tear of the constituting fibers. Examples of the fibers that make up the non-elastic fiber layer may include fibers formed from polyethylene (PE), polypropylene (PP), polyesters (PET and PBT), polyamides and the like. The fibers that make up the non-elastic fiber layer may be short fibers or long fibers, and may be hydrophilic or water-repellent. In addition, the type of core sheath or fibers combined side by side, divisible fibers, modified transverse surface fibers, tight fibers, thermal shrink fibers and the like can also be used. These fibers can be used for one type only or for a combination of two or more types. The non-elastic fiber layer may be a nonwoven fabric or fabric of continuous filaments or short fibers.
[0195] The elastic sheet of (b) mentioned above is obtained by conducting a stretch processing on a laminated sheet comprising an elastic layer having elastic stretch capability and substantially inelastic fiber layers that are laminated to one or both surfaces of the elastic layer, where the non-elastic fiber layers are partially joined in a regulated pattern.
[0196] Next, the first 1S laminated material that has undergone the tooth and groove processing mentioned above is cut several times in the lateral direction by an outer layer material cutter 211 and divided into several pieces for the production of narrow ribbon-like laminated materials 33T (33 outer layer materials). For example, the respective 33T tape-type laminated materials are cut to equal widths.
[0197] Additionally, the respective 33T ribbon-type laminated materials are fed into the space between a first top-side separation cylinder 251 and a first bottom-side separation cylinder 253 in the state in which the lateral direction positions during cutting are maintained similarly to the first aspect mentioned above. The various 33T tape-type laminated materials fed into the cylinder space are wound around the first top-side separation cylinder 251 and the first bottom-side separation cylinder 253 in an alternating manner to separate the 33T-type laminated materials into two different directions for the front side and the rear side.
[0198] When the 33T tape-type laminated materials to the rear side, which have been wound around the first upper side separation roller 251 and have been separated in the upper direction, wind around the second upper side separation roller 252, the second laminated material 2S is fed from the direction opposite to the feed direction of the first laminated material 1S (the direction of an arrow A1) so as to wrap directly around the second upper side separation cylinder 252, in the space between the first upper-side separation cylinder 251 and the second upper-side separation cylinder 252. At that time, the adhesive 32 is applied in advance by an adhesive coating apparatus 215 to the positions in which the tape-laminated materials 33T must adhere.
[0199] Additionally, a pressure is applied between the first top-side separation cylinder 251 and a second top-side separation cylinder 252, and the laminated tape-like materials 33T are adhered by an adhesive 32 applied to the bottom surface side of the second 2S laminated material by an adhesive application device (illustration is omitted). At that time, the 33T tape-type laminated materials are adhered to the second 2S laminated material in the state in which positions in the lateral direction during cutting are maintained. Additionally, the 33T tape-type laminated materials are adhered to the second 2S laminated material without departing from the first top-side separation cylinder 251. Thus, a continuous outer covering element 11S which must be the rear 23 made from the second 2S laminated material to which 33T tape-type laminated materials are added. In addition, both sides of the outer cover continuous element 11S for the rear 23 are inverted in the state in which the outer cover continuous element 11S is wound around the second upper side separation cylinder 252, and the continuous element external cover 11S is fed in the direction of an arrow A2.
[0200] On the other hand, tape-like laminated materials 33T to the front side are wrapped around the first lower-side separation cylinder 253 and are separated in the lower direction, additionally wound around the second lower-side separation cylinder 254 and are transported. A guide roller 255, which is arranged at the bottom of the second lower-side separation cylinder 254, feeds the second laminated material 2S (the inner layer material 31) to the front side in the direction of arrow A3 which is the same direction as the first laminated material 1S. At that time, adhesive 32 is applied in advance by an adhesive coating apparatus 215 to the positions in which the 33T tape-type laminated materials are to be attached from the second 2S laminate material.
[0201] Additionally, a pressure is applied between the second lower-side separation roller 254 and the guide roller 255, and the 33T tape-laminated materials are adhered to the second 2S laminated material by adhesive 32. At that time, the laminated materials type tape 33T are transported by winding around the bearing surfaces of the first lower-side separation cylinder 253 and the second lower-side separation cylinder 254 without sliding, and are thus attached to the second laminated material 2S in the state in which positions in the lateral direction during cutting are maintained. In addition, the 33T tape-type laminated materials are adhered to the second 2S laminated material while maintaining an almost constant tension without departing from the respective cylinder surfaces of the first lower-side separation cylinder 253 and second lower-side separation cylinder 254. As a result In addition, a continuous element of external cover 11S which must be the rear part 21 made from the second laminated material 2S to which the laminated materials type tape 33T are added. In addition, the continuous outer cover element 11S for the front 21 is fed in the direction of an arrow A5 from the space between the second lower-side separation roller 254 and the guide roller 255.
[0202] The adhesive 32 fed to the respective second laminated materials 2S is fed to a predetermined position (for example, approximately the central part or side of the lateral direction) where each 33T tape-type laminated material is addendum, and the feeding method it can be continuous or intermittent. As the adhesive 32, for example, a thermal melting adhesive, a double-sided adhesive tape and the like are used.
[0203] As explained above, in order for 33T tape-laminated materials to be added to the second 2S laminated material to which adhesive 32 is applied, it is necessary for the second 2S laminated material and 33T tape-laminated materials to be laminated to from the same direction, and fed into the space between the first and second top-side separation cylinders 251 and 252 and the space between the second bottom-side separation cylinders and the guide cylinder 254 and 255. By feeding in such a way, the attachment of the adhesive 32 applied to the second laminated material 2S to the cylinder surfaces can be avoided.
[0204] Next, the positions of the respective continuous outer cover elements 11S on the front 21 and rear 23 are adjusted to provide a predetermined interval D in a manner similar to the second aspect of the first embodiment mentioned above. In this position adjustment step, the feed direction of the continuous outer cover element 11S to the front 21 is set to be the parallel direction of an arrow A4 that is parallel to the feed direction (the direction of arrow A2) of the outer cover continuous element 11S to the rear 23, and the surface on the side of the second laminated material 2S of the outer cover continuous element 11S to the front 21 and the surface on the side of the second laminate material 2S of the continuous cover element outer 11S to the rear 23 are adjusted to be in the same plane direction (for example, the top surface) and at the same height. Subsequently, the production steps are similar to those of the production method as explained in the first modality mentioned above.
[0205] In this second embodiment of the production method of the present invention, effects similar to those of the first embodiment mentioned above can be obtained. Additionally, since the elasticity is printed on the 33T tape-laminated materials themselves, it is not necessary to arrange the elastic elements between the first 1S laminate material (the outer layer 33 materials) and the second 2S laminate material (the layer material internal 31), and this allows the reduction of materials and the reduction of material costs.
[0206] Additionally, since the first 1S laminated material is subjected to a stretch processing in order to have concave and convex parts, the soft appearance and touch are provided and ornaments can also be formed on the 33T tape-laminated materials by narrowing the width of application of the adhesive 32 than the width of the 33T tape-type laminated materials.
[0207] Additionally, by changing the widths of the 33T tape-type laminated materials, the elastic force is also changed and adjusted to an adequate constriction pressure corresponding to each location such as a waist, ilium and lumbar part. For example, by increasing the width more at the waist and at the ilium than elsewhere, the elastic strength can be improved and the constriction pressure can be increased.
[0208] Additionally, in the pull diaper 10 where the elastic elements are not arranged, in the case where the elasticity of the laminated areas is weak, the continuous elements of the elastic member 3S in the first modality can be intercalated between the first laminated material 1S and the second 2S laminated material as needed.
[0209] Next, the first aspect of the third embodiment of the production method according to the present invention will now be explained, with reference to figure 27 and figure 28. The first aspect of the third embodiment is a method of producing a diaper of pulling having a constitution in which the laminated materials type tape 33T having different widths are partially used in the pulling diaper mentioned above 10.
[0210] As illustrated in figure 27, and in figure 28, in a similar way to the first embodiment mentioned above, a first laminated material 1S (outer layer materials 33) is fed in the direction of an arrow A1 and is cut in the direction of feeding by using the outer layer material cutter 211 to supply the 33T narrow ribbon-type laminated materials (outer layer materials 33). At that time, for example, the 33T tape-type laminated materials (33Tc) to be arranged on the ilium bones are widened, and other 33T tape-type laminated materials are made to have equal widths. For example, 33Tc tape laminated materials are formed to be about 1.05 times to 3 times, preferably about 1.1 times to 2 times wider than other 33T tape-like materials. In addition, the respective ribbon-like laminated materials 33T are fed into the space between a first upper-side separation cylinder 251 and a first lower-side separation cylinder 253 in the state in which the positions in the lateral direction during cutting are maintained.
[0211] The various pieces of 33T tape-type laminated materials are wound around the first top-side separation cylinder 251 and the first bottom-side separation cylinder 253 in an alternating manner so that they can be separated in two different directions (for example, the top direction and the bottom direction). Specifically, the various pieces of 33T tape-laminated materials are separated into tape-laminated materials for the front and rear sides.
[0212] The 33T tape-type laminated materials for the rear side wrap around the first top-side separation cylinder 251 and are separated in the upper direction, and additionally wrap around the second top-side separation cylinder 252 and are carried in the upper direction. On the other hand, a pressure cylinder 257 is disposed on top of the second upper side separation cylinder 252. The second laminated material 2S to the rear side from the similar direction (the direction of an arrow A6) is fed to the feed direction of the first laminated material 1S (the direction of arrow A1) and is sent to the space between the second top-side separation cylinder 252 and the pressure cylinder 257. Additionally, in the space between the pressure cylinder 257 and the second upper-side separation cylinder 252, the continuous elements of elastic member 3S (elastic elements 35) to the front side to which an adhesive (not shown) is applied beforehand by an adhesive coating device 215 are fed to the side bottom of the second laminated material 2S from the direction that is similar to the feed direction of the first laminated material 1S (the direction of arrow A1), and the 33T tape-type laminated materials carried while and rolling around the second upper side separating cylinder 252, they are laminated and added through the continuous elements of elastic member 3S.
[0213] Therefore, a pressure is applied between the second top-side separation cylinder 252 and the pressure cylinder 257, and the 33T tape-type laminated materials are added to the second 2S laminated material through the continuous elements of the elastic member 3S through the adhesive. applied to the continuous elements of the elastic member 3S. At that time, the 33T tape-type laminated materials are added to the second 2S laminated material in the state in which positions in the lateral direction during cutting are maintained. In addition, the tape laminated materials 33T are added to the second laminated material 2S without departing from the respective cylinder surfaces of the first top-side separation cylinder 251 and second top-side separation cylinder 252. Each continuous element of the elastic member 3S for the rear side is fed, for example, so as to be arranged in the center of the lateral direction of each 33T tape-type laminated material to the rear side.
[0214] Additionally, several pieces (for example, three pieces in the illustration) of the continuous elements of elastic member 3S (3Sc) to be displayed in the bones of the ilium are fed without passing through the width of the 33T (33Tc) type tape laminated material since the 33Tc tape-type laminated material is formed to be wide in position.
[0215] Thus, the continuous outer covering element 11S, which must be the rear part 23, which is formed from the second laminated material 2S to which the laminated materials like tape 33T are adhered through the continuous elements of the elastic member 3S, is constituted. In addition, the continuous element of the outer cover 11S towards the rear 23 is fed in the direction of an arrow A7 in the state in which the 33T tape-type laminated materials are on the underside.
[0216] Additionally, both sides of the outer cover continuous element 11S to the rear side are inverted, and the outer cover continuous element 11S is fed in the direction of an arrow A2. To invert both surfaces, although not shown, as an example, a horizontal cylinder is arranged on the upper surface side (the side of the second laminated material 2S) of the continuous outer covering element 11S, the continuous outer covering element 11S is rotated by 90 around the feed direction as a geometric axis, and the surface of the second laminated material 2S of the continuous outer cover element 11S that has been rotated is received once by a vertical cylinder. In addition, the outer cover continuous element 11S is rotated by 90 around the feed direction as a geometry axis, and the upper surface side of the outer cover continuous element 11S that has been rotated is received by another horizontal cylinder. Thus, both surfaces of the continuous outer cover element 11S can be stably inverted around the feed direction as a geometric axis without oscillating in the lateral direction and height direction. As a result, in the continuous outer cover element 11S for the rear 23, the places where several pieces of the continuous members of elastic member 3Sc are adhered to a piece of the 33T type tape laminated material are arranged at the height of the ileum bones in the body pull diaper in subsequent steps.
[0217] On the other hand, for the front side, in a similar way to the third aspect of the first embodiment mentioned above, a pressure is applied between the second lower side separation cylinder 254 and the guide cylinder 255, and the laminated materials type 33T tape are adhered to the second laminated material 2S through the continuous elements of elastic member 3S by the adhesive applied to the continuous elements of the elastic member 3S. At that time, the 33T tape laminated materials are adhered to the second 2S laminated material in the state in which positions in the lateral direction during cutting are maintained. Thus, the continuous outer covering element 11S, which must be the front 21, which is formed from the second amine material I 2S to which the laminated materials of the tape 33T are adhered through the continuous elements of the elastic member 3S, is constituted. In addition, the continuous outer cover element 11S for the front 21 is fed in the direction of an arrow A5. As a result, in the continuous outer cover element 11S of the front 21, the locations where the various pieces of continuous elements of the elastic member 3Sc are adhered to a piece of 33T tape-like laminated material are arranged at the height of the ileum bones in the body pull diaper in subsequent steps.
[0218] Next, the positions of the respective external cover continuous elements 11S on the front 21 and rear 23 are adjusted to provide a predetermined interval D similar to the second aspect of the first modality mentioned above, In this position adjustment step , the feed direction of the outer cover continuous element 11S to the front 21 is set to the direction of the arrow A4 which is parallel to the feed direction (the direction of the arrow A2) of the outer cover continuous element 11S to the rear 23, and the side surface of the second laminated material 2S of the outer cover continuous element 11S to the front 21 and the side surface of the second laminated material 2S of the outer cover continuous element 11S to the rear 23 are arranged in the same flat direction (for example, the top surface) and at the same height.
[0219] By the steps mentioned above, the continuous outer covering element 11S for the front 21 and the continuous outer covering element 11S for the rear 23, where the wide ribbon laminated materials 33Tc are arranged on the outside, can be obtained.
[0220] The subsequent steps are similar to the steps as shown in the first modality mentioned above.
[0221] In the production method of the first aspect of the third modality mentioned above, action and effect similar to those of the first modality mentioned above can be obtained. Additionally, since several pieces of continuous element of the elastic member 3Sc can be added to a piece of the laminated material like ribbon 33Tc causing the laminated material like ribbon 33Tc to be disposed in the bones of the ileum, an advantage that the elastic force can reinforce and the force of constriction in the ileum bones is reinforced, and, in this way, the pull diaper becomes difficult to fall during the movement and the like, can be obtained.
[0222] Next, the second aspect of the third aspect will be explained, with reference to figure 29. When the 33Tc tape-type laminated materials to be created in a wide way in each of the front 21 and rear 23 are continuously placed in the first laminated material 1S, the gap with the other 33T tape-laminated materials is opened in an interval equivalent to the width of a 33Tc tape-laminated material on one side of the side direction of a 33Tc wide tape-laminated material in the 11S outer cover continuous element . Therefore, in the second aspect, a production method comprising creating gaps with the adjacent 33T tape laminate materials on both sides of the 33Tc wide tape laminate material equivalent to the gaps between the other 33T tape laminate materials will be explained below, with reference to figure 29.
[0223] As illustrated in figure 29, in the first laminated material 1S, the 33Tc wide ribbon laminated materials in the front 21 are pulled to one side, and the 33Tc wide ribbon laminated materials in the rear 23 are pulled to the other side. . Thus, at the front 21, the intervals with the 33T tape-laminated materials on both sides of the 33Tc wide-tape laminate material become equivalent to the intervals between many other 33T tape-laminated materials. Additionally, also at the rear 23, the intervals with other 33T tape-type laminated materials on both sides of the 33Tc tape-type laminate material become equivalent to the intervals between many other 33T tape-type materials. Thus, it becomes possible to make the widths of a portion of the 33T tape-laminated materials large in the state in which the intervals of the 33T tape-laminated materials are made equivalent.
[0224] In this case, for fixing 33T tape-type laminated materials to a second 2S laminated material, which is not illustrated, through the continuous elements of the elastic member 3Sc, the production methods in the first and second modes mentioned above can be applied .
[0225] Although in the third aspect mentioned above, two pieces of 33Tc tape-laminated materials are taken wide and several pieces of continuous elements of the elastic member 3S that correspond to the 33T-tape laminated materials are arranged, the number of continuous member elements elastic 3S corresponding to 33Tc tape-laminated materials on the front 21 and the number of continuous elements of 3S elastic member corresponding to 33Tc tape-laminated materials on the rear 23 may be different. In addition, the continuous elements of the elastic member 3S having different sizes can be arranged.
[0226] For example, in cases where the continuous elements of the elastic member 3S are arranged on the waist, ileum bones, lumbar and the like, the numbers of the respective continuous elements of the elastic member 3S on the front 21 and the rear 23 can be changed . By increasing the number of continuous elements of the elastic member 3S, the elastic force can be reinforced, and, thus, a strong constriction force can be obtained. Alternatively, the numbers of the respective elastic member continuous elements 3S on the front 21 and the rear 23 may be different. For example, by adjusting the number of continuous members of elastic member 3S at the rear 23 to be greater than at the front 21, the elastic force at the rear 23 can be reinforced and the diaper drop can be suppressed. In addition, by adjusting the number of continuous members of elastic member 3S on the front 21 so that it is greater than that of the rear 23, the elastic strength of the front 21 can be reinforced and the diaper drop can be suppressed.
[0227] Next, the case in which a pull diaper is created by using 33T tape-type laminated materials cut in equal widths will be explained below, with reference to figure 30. Figures 30 to 32 are illustrated by shading to facilitate understanding the positions of 33T tape-type laminated materials.
[0228] Figure 30 (1) illustrates a side view of the main part of a diaper made using the 33T tape-type laminated materials cut in equal widths. The respective 33T tape-type laminated material numbers arranged on the front 21 and the rear 23 are the same. The feeding positions of the second laminated materials 2S arranged respectively at the rear 23 and the front 21, with respect to the 33T tape-laminated materials are adjusted so that the position relationship between the second 2S laminated material and the 33T-tape laminated materials at the rear 23, and the position relationship between the second laminated material 2S and the tape-type laminated materials 33T at the front 21 become similar. That is, the distances between an end side in the lateral direction of the second 2S laminate material and the end side in the side of the anterior end side up in the lateral direction of the 33T tape-like laminate material which is closest to the first end side above are adjusted to be the same. When a diaper is made by using the second laminated material 2S to which the laminated materials like tape 33T are adhered, the laminated materials like tape 33T added to the second laminated material 2S arranged in the front 21 and the laminated materials like tape 33T adhered to the second laminated material 2S arranged at the rear 23 are superimposed on a side sealing part 25. In this case, the side sealing part 25 has a strong-weak sealing relationship, and thus the ease of removal on the side sealing part 25 is perfected.
[0229] In the example mentioned above, the width of the second laminated material 2S disposed at the front 21 and the width of the second laminated material 2S disposed at the rear 23 are the same. The same will now be applied to the widths of the second 2S laminated materials.
[0230] Additionally, it is possible to move the position relationship between the 33T tape-laminated materials arranged in the front 21 and the 33T-tape laminated materials arranged in the rear 23 in the state in which the diaper is created, by changing the positions of feeding the second laminated materials 2S in relation to the 33T tape-type laminate during the adhesion of the 33T tape-type materials. For example, by displacing the feed position of the second laminated material 2S by the width of a piece of the laminated material type 33T tape from the constitution illustrated in figure 30 (1), the laminated materials type 33T tape added to the second laminated material 2S arranged at the rear 23 there are disposed between the laminated materials 33T tape addicted to the second laminated material 2S disposed at the front 21 at the side sealing part 25, as shown in figure 30 (2), and the laminated materials 33T tape type are not overlapping each other. In this case, it is not necessary to adjust the flow of the second 2S laminated material, the processing can be carried out without paying attention to the transport property of the entire external cover.
[0231] Additionally, the case in which the numbers of 33T tape-laminated materials arranged in the front 21 and the 33T-tape laminated materials arranged in the rear 23 are different, for example, the case in which one is an odd number and the other is an even number will be explained below.
[0232] For an example, the case in which the number of 33T tape-laminated materials arranged in the front 21 is equal to six and the number of 33T tape-laminated materials arranged in the rear 23 is equal to seven will be explained, with reference to figure 31 (1). In the case where the second laminated material 2S arranged at the front 21 and the second laminated material 2S arranged at the rear 23, to which the 33T tape-type laminated materials separated by an outer layer material cutter (not shown) are attached, in the same position in a flat view (however, the positions in the height direction are different), the distance a between an end side in the lateral direction of the second laminated material 2S arranged on the rear 23 and the end side on the side of an end side mentioned above in the lateral direction of the tape-like laminate material 33T which is closest to that end side, and the distance b between an end side in the lateral direction of the second laminate material 2S disposed in the front 21 and the side of end on the side of an end side mentioned above in the lateral direction of the 33T tape-type laminate material that is closer to that end side, are different in width one of the 33T tape-type laminated material. The second 2S laminated material has been fed with respect to the 33T tape-laminated materials so as to be arranged in such a way, and the second 2S laminated material and the 33T tape-laminated materials are added to each other, and a diaper is created by using of the second 2S laminated materials. In that case, the position relationship between the 33T tape-laminated materials arranged at the front 21 and the 33T-tape laminated materials arranged at the rear 23 is an alternately arranged state, and those tape-laminated materials are not overlapping.
[0233] Additionally, the case in which the numbers of 33T tape-type laminated materials arranged on the front 21 and rear 23 are different as mentioned above will be explained, with reference to figure 31 (2). This example is the case in which the distance a between an end side in the lateral direction of the second 2S laminated material disposed in the rear 23 and the end side in the side of an end side mentioned above in the lateral direction of the tape-like laminated material 33T which is closest to that end side, and the distance b between an end side in the lateral direction of the second laminated material 2S disposed in the front 21 and the end side in the side of an end side mentioned above in the lateral direction of the 33T tape-type laminate material that is closest to that end side, are the same. The second 2S laminated materials were fed to the 33T tape-laminated materials so as to be arranged in such a way, the second laminated material and the tape-laminated materials are adhered to each other, and a diaper is created by using the second 2S laminated materials. In that case, the laminated materials 33T tape arranged at the front 21 and the laminated materials 33T tape arranged at the rear 23 are superimposed on the side sealing part 25 of the diaper. Since 33T tape-laminated materials are disposed less at the front 21 than at the rear 23, the 33T tape-laminated material from the front 21, which is not superimposed on the 33T tape-laminated materials at the rear 23, are generated on the side sealing part 25.
[0234] In cases where the constitutions illustrated in figure 31 (1) and (2), adjustments of the stretch and tension range are possible, and the freedom range of the outer cover specification (for example, designation tension tension) constriction) is increased. In addition, in any constitution, since the 33T tape-type laminated materials at the rear 23 are a lower part, the ability to fit the glutes is excellent.
[0235] Next, the case in which a pull diaper is created by using 33T tape-type laminated materials comprising 33Tc tape-type materials cut in different widths will be explained below, with reference to figure 32.
[0236] The side view of the main part of the diaper shown in figure 32 is the case of the 33T tape type laminate material comprising the 33Tc tape type laminate materials with different widths illustrated in figure 28, and the feeding positions of the second 2S laminated materials with With respect to 33T tape-type laminated materials, the second laminated material and 33T-tape laminated materials are adhered to each other, and a diaper is created by using these second 2S laminated materials. In that case, the laminated materials 33T tape arranged in the front 21 and the laminated materials 33T tape arranged in the rear 23, in the side sealing part 25 of the diaper, are overlapped. Additionally, 33Tc tape-laminated materials having different widths are superimposed on each other.
[0237] Next, another example in which a pull diaper is created by the use of 33T tape-type laminated materials comprising the 33Tc tape-type laminated material cut into different widths will be explained below with reference to figure 33.
[0238] The side view of the main part of the diaper shown in figure 33 is the case in which the 33T tape-laminated materials comprising the 33Tc tape-laminated materials with different widths illustrated in figure 29, and the feeding positions of the second laminated materials 2S with respect to the 33T tape-type laminated materials have been adjusted, the second laminated material and the tape-type laminated materials are added to each other and a diaper is created by using these 2S laminated materials. In that case, the tape-like laminated materials 33T arranged in the front 21 and the tape-like laminated material 33T arranged in the rear 23 are superimposed on the side sealing part 25 of the diaper. In addition, 33Tc tape-laminated materials with different widths are also superimposed on each other. Additionally, 33Tc tape-laminated materials with different widths arranged at the front 21 and 33Tc-tape laminated materials with different widths arranged at the rear 23 are superimposed on the side sealing part 25. Additionally, the positions between the tape-laminated materials 33T, which correspond to the positions from which 33T tape-type laminated materials with different widths have been removed, are also overlapped.
[0239] In the following, a method of adjusting the positions of the respective external cover continuous elements 11S arranged in the front 21 and rear 23 to provide a predetermined interval D in the modalities explained in the figures 24 to 27 mentioned above will be explained. Examples of such a method include, the addition to a method by a combination of cylinders mentioned above, a method comprising feeding the second sheet 2S arranged on the rear side and the second sheet 2S arranged on the front side so that the 33T tape-like materials are arranged on the surface side and feeding the two second sheets 2S in the parallel direction using a spacing device (not shown), similarly to the production method of the pull diaper 10 as explained by the figures 10 to 13 mentioned above. In this method, the height of the second laminated material 2S arranged on the rear side and the height of the second laminated material 2S arranged on the front side are different, and the difference in height can be adjusted to the same height using, for example, two cylinders (not shown).
[0240] In the following, the fourth embodiment according to the production method of a pull-on garment of the present invention will be explained, with reference to figure 34. Figure 34 is a plan view of the main part illustrating the case in which several pieces of continuous elements of elastic member 3S are fed each time in figure 21 (1) of the first embodiment mentioned above, unlike the first and third embodiments mentioned above. Additionally, the fourth modality uses the maintenance of intervals of the 33T tape-type laminated materials without lack of alignment of the cut to the adhesion to the second laminated material 2S in the first to third modes mentioned above.
[0241] As shown in figure 34, it is possible to feed several pieces of continuous element of thin elastic member 3S to a laminated material like 33T tape, and to adhere the second laminated material 2S to laminated material like 33T tape by interleaving several by continuous elements of elastic member 3S between them. At this time, it is preferable to consider the width and number of continuous elements of thin elastic member 3S so that the elastic force similar to the elastic force of a continuous element of elastic member 3S consisting of a piece can be obtained. In addition, since the positions of the 33T tape-type laminated materials in the lateral direction during cutting are maintained, the adjustment of the 33T-tape-type materials is carried out with high precision, therefore, even several pieces of continuous elements of elastic member 3S are performed. adhered to a piece of the 33T tape-type laminate material, the adhesion can be conducted so that the continuous elements of the elastic member 3S fit the width of the 33T-tape laminate material without leaving the 33T-tape laminate material.
[0242] Therefore, since several hairs of the 3S elastic member continuous elements can be attached to a piece of 33T tape-type laminated material, the continuous members of the 3S elastic member may be less visible because they are made thin without reducing the stretching force, a user becomes less aware of the constriction force by the elastic elements (the continuous elements of the elastic member 3S) and the wearing comfort can be improved.
[0243] For example, although it depends on the 33T tape laminate material, in the case where the 33T tape laminate material having a base weight of about 16 g / m2 and a thickness of about 0.02 mm is used, continuous elements of the elastic member 3S become less visible by using each one having a width of about 0.1 mm to 1 mm and adjusting their intervals to about 1 mm to 5 mm, and it is preferable that the width is adjusted to about 0.1 mm to 0.3 mm and the intervals are adjusted to about 2 mm to 4 mm.
[0244] The respective modalities mentioned above and the respective aspects can be combined in an appropriate way.
[0245] For example, the fourth modality can be combined with the first to the third modalities mentioned above.
[0246] The case in which the second aspect of the third modality mentioned above and the fourth modality mentioned above are combined will be explained. For example, in the first laminated material 1S, for the parts from which the 33Tc tape-laminated materials have been removed for the front 21, intervals that correspond to the 33Tc tape-laminated materials are formed at the rear 23. Therefore, by the adhesion of several pieces of the continuous members of elastic member 3S to the parts of the 33T tape-laminated materials that are adjacent to both sides of the parts in which the range of the 33T tape-laminated materials is wide at the rear 23, the tensile strength in those parts can be reinforced to thereby reduce the coverage of the elastic force in those parts where the intervals of 33T tape-type laminated materials are extended.
[0247] Although a pull diaper is exemplified as the pull garment of the present invention in the respective modalities mentioned above, a pull diaper cover for disposing an absorbent body on the side of the skin surface is also preferable. The absorbent body is not specifically limited as long as it absorbs discharged urine and the like, and examples may include absorbent parts such as urine collection elements. Examples of absorbent parts may include an absorbent part comprising a liquid-permeable top sheet, a liquid-impermeable leak prevention sheet and a liquid-retaining absorbent core that is sandwiched between the two sheets, and formed in such a longitudinal shape as a rectangular shape in a flat view. Additionally, it is preferable that a combined pair of three-dimensional protections are formed on both sides in the longitudinal direction of the absorbent part, and it is preferable that laminated materials having three-dimensional elastic protective elements for forming three-dimensional protections are arranged on both sides of the direction. longitudinal of the absorbent part as the respective steric protections. Such an absorbent part is arranged in such a way that the longitudinal direction creates a bridge between the back side and the front side of a user through the groin to thereby arrange the permeable and liquid side of the part so as to come into contact with the user's skin. It is preferable that the diaper cover is used in such a way as to wrap the absorbent part.
[0248] Additionally, the pull-on garment of the present invention is a concept that comprises general absorbent articles having a pull structure such as hygienic shorts and sanitary pads, in addition to the pull diapers mentioned above. The pull-on garment can be for children or adults.
[0249] Having described the invention as related to the present embodiments, it is the intention that the invention should not be limited by any detail of the description unless otherwise specified, but rather be constructed broadly within the spirit and scope as presented in the appended claims.
