    [0001] [001] The present invention relates to an apparatus and method for supplying a continuous web of wrinkled sheet material.
    [0002] [002] Such an apparatus is known, for example in GB5793114A, in the field of producing filters for smoking articles such as cigarettes. These filters are typically made of cellulose acetate fiber or a wrinkled sheet material, for example, paper. The creased paper is supplied to a filter making device in the form of a continuous web. The filter making device forms a filter bar from the web of wrinkled paper supplied to the filter making device, and subsequently cuts the filter bar into discrete filters of a predetermined length.
    [0003] [003] An apparatus for supplying a continuous web of wrinkled paper to a filter making device is known. In the prior art apparatus, the outlet of the creasing unit is arranged so as to directly feed the creased paper into the filter making device. A control unit controls the various units of the device and their operation, allowing little flexibility for variation, for example, with respect to the manufacture of different types of filters.
    [0004] [004] It would be desirable to provide an apparatus which provides improved flexibility with respect to various types and properties of filters that can be made using the corrugated sheet material supplied by the apparatus. This would provide improved productivity and cost efficiency to meet a variety of consumer needs.
    [0005] [005] In one aspect, the present invention provides an apparatus for supplying a continuous web of wrinkled sheet material to a bar forming device. The apparatus comprises a winding unit for unwinding the sheet material from a support on which the sheet material is provided, such as a spool, and a wrinkling unit for wrinkling the sheet material. The apparatus further comprises a supply unit for adding particulate or liquid supplement material to the sheet material, and a control unit for controlling the various units of the apparatus in response to sensor signals received from the respective units.
    [0006] [006] The supply unit is arranged downstream of the corrugation unit when viewed in the direction of transport of the sheet material, and upstream of a bar forming device to which the corrugated sheet material is supplied. Thus, particulate or liquid supplement material can be added to the corrugated sheet material before the corrugated sheet material is supplied to a bar forming device, for example, to a filter making device. Alternatively, the bar forming device can be comprised in the apparatus according to the invention.
    [0007] [007] Adding supplement material after wrinkling is advantageous. For example, as supplement material is added to the already corrugated sheet material, the supplement material or at least a substantial amount thereof is retained within or on the corrugated structures of the sheet material. The sheet material corrugated with the supplement material is subsequently supplied to the bar forming device where a bar of filter material is formed which is then cut to size to form the individual filters having a predetermined length. Preferably, the delivery device is arranged directly upstream of the bar forming device. Hereby, no loss of, for example, particulate material or alteration of a sprayed liquid on the sheet material needs to be considered, since the sheet material is supplied to the bar forming device directly after the supplement material has been added.
    [0008] [008] The term "sheet material" in this respect means to comprise any flat sheet of a material suitable for the production of filters for smoking articles, such as, for example, paper or plastic films. The sheet material can be either a single layer sheet material or it can be a multilayer sheet material.
    [0009] [009] The term "particulate material or liquid supplement material" includes liquids, but, for example, also materials such as gel or paste, as well as particulate materials that comprise, for example, discrete particles, such as raw material, powder, granules or the like, and objects suitable for inclusion in a cigarette filter, such as capsules or beads. Preferably, the supplement material is a particulate material.
    [0010] [0010] The addition of particulate material or liquid supplement to the corrugated sheet material can generally serve several purposes. For example, it can serve the purpose of supplementing the smoke consumed by a consumer through the filter. For example, the supplement material may comprise menthol, tobacco or other desired flavors. Alternatively, or in addition, the supplement material may serve to remove or alter at least part of the gaseous or solid constituents of the smoke. For example, the added particulate material may comprise granules of activated carbon.
    [0011] [0011] Also, the resistance to swallow of the final filter can be varied by adding the supplement material. For example, by varying the amount of the supplement material, for example, particulate material, added to the sheet material per sheet material unit, the resistance to swallowing can be decreased or increased. Preferably, the liquid supplement material does not influence the swallowing resistance of the filter.
    [0012] [0012] The resistance to swallowing can also be varied by other capabilities of the apparatus, thus increasing the flexibility of the apparatus according to the invention. Because the apparatus is capable of processing different types of sheet material, the resistance to swallowing can be varied by selecting the type of sheet material processed. As an example, it is possible to select paper or plastic wrap. Also, single-layer sheet materials or multi-layer sheet materials can be selected. Furthermore, because the apparatus is capable of processing sheet materials that have different thicknesses, the resistance to swallowing can be varied by selecting the thickness of the sheet material processed by the apparatus. Furthermore, because the apparatus is able to process sheet materials having different widths, the resistance to swallowing can be varied by selecting the width of the sheet material processed by the apparatus. The width of the sheet material is related to the density of the corrugated sheet material within the filter after forming the bar. Therefore, the apparatus according to the invention is very flexible and allows the supply of corrugated sheet material, which allows the production of filters of a wide variety of types and properties. In addition, an apparatus according to the invention is specifically advantageous since the cost to manufacture filters that comprise corrugated sheet material is typically lower than the cost to manufacture filters that comprise cellulose acetate fibers.
    [0013] [0013] According to an aspect of the apparatus according to the invention, the wrinkling unit comprises a first pair of wrinkle rollers for coupling and wrinkling the continuous web of sheet material being transported between them. The wrinkle rollers have a surface which is provided with a means adapted to wrinkle the sheet material in the direction of transport of the sheet material. Preferably, the wrinkle rollers have a surface which is provided with a means adapted to wrinkle the sheet material in the longitudinal direction of the sheet material. As an example, the means adapted to wrinkle the sheet material in the direction of transport of the sheet material may comprise a structure on the surface of the rollers. Specifically, such a structure may comprise, for example, edges and rails that run circumferentially around the geometric axis of rotation of the rollers. The sheet material is creased by transferring the structure to the sheet material as it passes between the rollers. The grooved structure transferred to the sheet material is specifically suitable for receiving the supplement material, specifically if the supplement material is a particulate material, or comprises capsules or beads. The wrinkling of the sheet material in the longitudinal direction also reduces the stability of the sheet material in a transverse direction. Thus, the subsequent formation of the bar (compression of the sheet material into a cylindrical shape) which is then cut to form the individual filters is facilitated.
    [0014] [0014] According to another aspect of the invention, the wrinkle unit comprises a second pair of wrinkle rollers for coupling and wrinkling the continuous web of sheet material being transported between them. The wrinkle rollers of the second pair of wrinkle rollers have a surface which is provided with a means adapted to wrinkle the sheet material in a direction transverse to the direction of transport of the sheet material. The term "transverse to the direction of transport of the sheet material" should be understood to include directions other than perpendicular to the direction of transport of the sheet material. Preferably, the wrinkle rollers have a surface which is provided with a means adapted to wrinkle the sheet material in a direction perpendicular to the direction of transport. As an example, the means adapted to wrinkle the sheet material in the direction transverse to the direction of transport of the sheet material may comprise a structure on the surface of the rollers. This structure can comprise edges and rails that run in a direction parallel to the geometric axis of rotation of the rollers. This structure is preferably provided over the entire surface of the rollers, so that the sheet material is wrinkled by transferring the structure of the rollers to the sheet material as it passes between the rollers. Alternatively, in some applications, it may be sufficient to wrinkle the sheet material only in sections in a transverse direction, so that some sections are wrinkled and others remain unwrinkled in a transverse direction.
    [0015] [0015] According to a still further aspect of the invention, the wrinkle unit comprises rather a first pair of wrinkle rollers than both a first pair of wrinkle rollers having a surface being provided with a means adapted to wrinkle the material of sheet in a longitudinal direction in relation to the direction of transport of the sheet material, as a second pair of wrinkle rollers having a surface being provided with a means adapted to wrinkle the sheet material in a direction transverse to the direction of transport of the sheet. sheet material. This modality allows both the wrinkling of the sheet material in the longitudinal and transverse directions, resulting in a specific pattern being transferred to the sheet material as the sheet material passes between the first and the second pair of rollers. The structure on the surface of the respective pair of rollers can be incorporated as described above.
    [0016] [0016] For any of the modalities described above the particulate or liquid supplement material added to the corrugated sheet material by the application unit is preferably applied within the structure created in the corrugated sheet material, for example, within the longitudinally running gutters , inside the gutters that run transversely or inside the depressions of the pattern generated by the first and second pairs of rollers. This is particularly advantageous if the supplement material is a particulate material. The particulate material applied within these gutters or depressions is retained therein as the corrugated sheet material is subsequently fed into the bar forming device where the corrugated sheet material is then compressed to form a bar. As preferably no further manipulation step of the sheet material is required between the addition of the supplement material and the bar forming device, the added particulate or liquid material remains in place, for example, within the corrugated structure in the case of material particulate or is not transferred to other locations, for example, if the liquid material does not dry out immediately.
    [0017] [0017] In accordance with yet another aspect of the invention, the apparatus further comprises a cutting unit for cutting the continuous web of sheet material to a predetermined width.
    [0018] [0018] The cutting unit is arranged upstream of the corrugation unit when viewed in the direction of transport of the sheet material. This aspect is advantageous since it allows to cut the sheet material in different widths, which, as mentioned above, allows the control of the density of the filter bar. For this purpose, the cutting elements are movable in a direction perpendicular to the direction of transport of the sheet material. Preferably, the cutting elements are symmetrically displaceable with respect to the center line of the path along which the sheet material is transported through the apparatus. This allows the sheet material of the sheet to be cut to a desired width and offers many advantages.
    [0019] [0019] For example, common filter cigarette filters have a diameter of approximately 7.6 mm (mm), while filters of so-called "fine cigarettes" have a diameter of approximately 7.1 mm (mm). Consequently, when a sheet of sheet material has been processed for the production of filters for common filter cigarettes and it is now desired to switch the production of filters for fine cigarettes, until now the coil that carries the sheet for the filters of common filter cigarettes it is replaced by a coil that carries a sheet that is the width required for fine filter cigarette filters. This coil replacement is a comparatively laborious and time-consuming process. An advantage of the modality of the apparatus comprising the cutting unit described above is that such replacement of the coil is no longer required. Instead, the cutting unit can be adjusted to cut the leaf material for the production of filters for common filter cigarettes to the required width for fine filter cigarette filters as the sheet material sheet passes through the cutting unit.
    [0020] [0020] An additional advantage of the cutting unit is that it allows easy variation of the resistance to swallow. By cutting the sheet material to a smaller width, the amount of corrugated sheet material contained in the filter is reduced thereby reducing the resistance to swallowing as the other parameters, for example, the amount of particulate material or liquid supplement applied , remains unchanged. Also, if a specific resistance to swallowing is desired and a specific sheet material is to be processed the sheet material can be cut to a width which is such that after wrinkling and bar formation results in the desired resistance to swallowing. Consequently, this allows the processing of different types of sheet materials, for example, paper or plastic film, as well as different widths of sheet materials.
    [0021] [0021] In accordance with yet another aspect of the invention, the winding unit may comprise a motor for driving the coil on which the sheet material is provided, and a brake. The control unit controls the motor and the brake in such a way as to prevent the continuous web of sheet material from breaking. In the state of the art, the sheet material has so far been pulled through the apparatus by the wrinkle rollers or by additional drive rollers of the wrinkle unit. According to the present invention, the motor of the winding unit assists in the unwinding of the sheet material from the bobbin which is specifically advantageous in case the sheet material is fragile. The brittle sheet material tends to break when a very high tensile force is applied by the rollers that pull the sheet material through the apparatus. The occurrence of excessively high tractive force can thus be avoided. Preferably, the control unit receives a signal indicative of the actual tension of the sheet material. This signal can be processed and the motor of the winding unit can be controlled in response. Also, the winding unit's brake can be controlled by the control unit. As the bobbin is close to being empty, that is, at the moment when there is only little sheet material remaining on the bobbin, the bobbin rotation must be stopped. The brake serves to achieve a smooth braking profile in order to avoid breaking the sheet material during this phase.
    [0022] [0022] According to a still further aspect of the invention, the apparatus further comprises a tensioning unit comprising a controlled actuator for applying and maintaining a predetermined tension on the sheet material during the transport of the sheet material through the apparatus. Although passive tensioning units are known in the art, a tensioning unit comprising a controlled actuator is advantageous in that it allows active control of the tension applied to the sheet material. For example, the known prior art tensioning units comprise a passive tensioning element that has a fixed mass or weight through which tension is applied to the sheet material, however, this tension cannot be actively controlled. As an example, the controlled actuator according to this aspect of the invention can be a controlled pneumatic actuator, a controlled hydraulic actuator, a controlled electric actuator or it can be any other suitable type of controlled actuator, in order to actively control the tension applied to the material of leaf.
    [0023] [0023] According to a still further aspect of the invention, the apparatus further comprises a softening unit which is arranged upstream of the wrinkling unit. The softening unit serves to facilitate the wrinkling operation by softening the sheet material to be wrinkled. As an example, the softening unit may comprise a heat source to increase the temperature of the sheet material to be wrinkled. Such a softening unit comprising a heat source is specifically advantageous for plastic sheet material. An increase in temperature of the plastic sheet material softens the sheet material and can thus facilitate the wrinkling of the sheet material. Any conventional heat source can be used for this purpose, such as, for example, an infrared radiator. Alternatively or in combination, the softening unit may comprise a moisture control means which is capable of increasing or decreasing the moisture content of the sheet material. For example, to increase the moisture content of the paper sheet material, the moisture control means may comprise a nozzle arrangement for humidifying the paper sheet material to be wrinkled. If the moisture content is too high, the heat source can be activated to decrease the moisture content of the paper sheet material.
    [0024] [0024] The cutting unit mentioned above is specifically useful in combination with the application unit.
    [0025] [0025] Additional advantageous aspects of the invention will be apparent from the following description of an embodiment of the apparatus according to the invention with the aid of the drawings in which:
    [0026] [0026] Figure 1 shows a schematic representation of an embodiment of the apparatus according to the invention;
    [0027] [0027] Figure 2 shows a schematic representation of a first embodiment of two wrinkle rollers of the apparatus according to the invention; and
    [0028] [0028] Figure 3 shows a schematic representation of a second type of two wrinkle rollers (upper right) of the apparatus according to the invention, as well as two schematic arrangements (upper and lower left) of edges and rails provided on the surface of the wrinkle rollers.
    [0029] [0029] In Figure 1, an embodiment of the apparatus according to the invention is shown in a schematic representation. The apparatus comprises a drive unit 1 comprising drive rollers 10 for coupling and transporting a sheet material 2 in drive through the apparatus. For example, sheet material 2 can be a suitable paper or plastic film. The sheet material 2 is stored as a spool 20 on a reel 21 from which the sheet material 2 can be unwound with the aid of a winding unit 3.
    [0030] [0030] The winding unit 3 comprises a motor 30 and a brake 31 capable of acting on the coil 21 in order to apply an additional driving force or braking on the coil 21. This is described in more detail below. A sensor 32 is provided in order to detect the distance between the sensor 32 and the outermost layer of the spool 20 in order to determine if there is sufficient sheet material remaining on the coil 21 to continue the operation.
    [0031] [0031] The sheet material 2 is transported through the apparatus in the form of a sheet. A number of transport rollers 11 are provided along the path of the sheet of sheet material 2 through the apparatus. These transport rollers 11 serve to secure or guide the sheet of sheet material 2 over its path through the apparatus.
    [0032] [0032] The apparatus further comprises a tensioning unit 4 for applying and maintaining a predetermined tension on the sheet of sheet material 2 as it is transported through the apparatus. For this purpose, the tensioning unit 4 comprises a controlled actuator 40 which can be actively controlled so as to always maintain the desired predetermined tension in the sheet of sheet material 2 even if conditions during operation change.
    [0033] [0033] The apparatus further comprises a cutting unit 5 for in-line cutting of sheet material 2 to the desired width. As explained above, whether the width of the sheet material 2 to be supplied by the apparatus should be changed (for example, due to a change from the production of filters for cigarettes with common filters to the production of filters for fine cigarettes, or for any other reason). another reason, see above) it is no longer necessary to interrupt production and change the reel 21 which carries the spool 20, but instead the cutting unit 5 allows to cut the sheet material 2 in line to the desired width. The cutting unit 5 will be described in more detail below.
    [0034] [0034] The apparatus further comprises a softening unit 6 to increase the temperature of the sheet material 2. The softening unit is arranged upstream of a wrinkle unit 7 to wrinkle the sheet material 2. The softening unit 6 assists in softening the sheet material 2 to facilitate the wrinkling of the sheet material 2. As already explained above, the softening unit 6 can comprise a heat source such as an infrared radiator, however, it can also comprise any other type suitable radiator for this purpose. Such a heat source is specifically advantageous if the sheet material 2 is a plastic sheet material. Alternatively or in combination, the softening unit 6 may comprise a moisture control means which is capable of increasing or decreasing the moisture content of the sheet material 2. This is particularly advantageous if the sheet material 2 is a material of sheet of paper. For example, to increase the moisture content of the paper sheet material, the moisture control means may comprise a nozzle arrangement for humidifying the paper sheet material to be wrinkled. If the moisture content is too high, the heat source can be activated to decrease the moisture content of the paper sheet material.
    [0035] [0035] As already mentioned, the apparatus further comprises a wrinkle unit 7 for wrinkling the sheet material 2. The wrinkle unit 7 can comprise a longitudinal wrinkle unit 70, or a side wrinkle unit 71, or both a unit longitudinal wrinkle unit 70 as well as a side wrinkle unit 71. The longitudinal wrinkle unit 70 as well as the side wrinkle unit 71 can comprise one or more pairs of rollers, as will be described in more detail below with the aid of Figure 2 and the Figure 3.
    [0036] [0036] The apparatus further comprises an application unit 8 for adding a particulate material or liquid supplement to the sheet material 2. As already mentioned, the supplement material is preferably a particulate material or a liquid, the liquid of which does not change the resistance to swallow. The application unit 8 is arranged downstream of the corrugation unit 7 when viewed in the direction of transport of the sheet material 2, and upstream of a bar forming device to which the sheet material is supplied by the apparatus directly after the material particulate or liquid has been added. Suitable bar forming devices are well known in the art, and therefore they are not described in detail.
    [0037] [0037] Finally, the device comprises a control unit 9 for controlling the various units, as this is indicated by the various dashed lines and arrows in Figure 1.
    [0038] [0038] In operation the sheet material 2 stored as a spool 20 is unwound from the coil 21. Drive rollers 10 of the drive unit 1 apply tensile forces to the sheet material sheet 2 causing the sheet material 2 to be unwound from the spool 20 stored on the spool 21. However, these forces can vary to a certain degree. As the rupture of the sheet material 2 must be avoided, as the control unit 9 receives a signal from the drive unit 1 representative of high tensile forces, the control unit 9 can cause the motor 30 to apply an additional torque to the spool 21 in order to prevent sheet material 2 from breaking. In a similar way, the control unit 9 can cause the brake 31 to decrease the rotational speed of the coil 21 so as to increase the tension of the sheet material 2 in case the tension has become too low. Also, when there is only a small amount of sheet material 2 remaining on the reel 20 - this being detected by the sensor 32 - the brake 31 will assist in controlling the rotational speed of the coil 21 to avoid rupture of the sheet material 2 during the stop phase.
    [0039] [0039] As already mentioned above, the tensioning unit 4 comprising the controlled actuator 40 assists in the application and maintenance of a predetermined tension of the sheet material 2. This allows a reliable transport of the sheet material 2 through the apparatus and on the other side prevents sheet material 2 from actively breaking by controlling the tension of sheet material 2.
    [0040] [0040] In the additional path of the sheet material 2 through the apparatus, the cutting unit 5 can cut the sheet material 2 to the desired width in case the sheet material 2 unwound from the spool 20 is no longer the required width. For this purpose, the cutting unit 5 may comprise two laterally adjustable cutting wheels 50 (only one of which is shown in Figure 1) which can be adjusted in a direction perpendicular to the direction of transport of the sheet material 2. Preferably, the cutting wheels 50 are symmetrically displaceable with respect to a center line of the sheet material path 2.
    [0041] [0041] Looking again at Figure 1, with the aid of the softening unit 6 the sheet material can be heated or humidified before being wrinkled in order to soften the sheet material 2 to facilitate the wrinkling.
    [0042] [0042] The sheet material 2 then enters the corrugation unit 7 which may comprise either a longitudinal corrugation unit 70 or a side corrugation unit 71, or both a longitudinal corrugation unit 70 and a lateral corrugation unit 71. For example, the side wrinkle unit 71 comprises a pair of wrinkle rollers 710 as shown in Figure 2. As the sheet material 2 passes through the wrinkle rollers 710 it is wrinkled in a direction transverse to the direction of transport of the wrinkle material. sheet 2. In the embodiment shown in Figure 2, sheet material 2 is wrinkled in a direction perpendicular to the transport direction, as this can be seen from the arrangement of edges 711 and rails 712 on the surface of the wrinkle rollers 710. The lines dashes 713 on the sheet material 2 shown in Figure 2 are intended to indicate the grooves that have been wrinkled within the sheet material 2 in the direction of the dashed lines 713.
    [0043] [0043] The longitudinal wrinkle unit 70 can also comprise a pair of rollers 700, as this is shown in Figure 3 (top right). However, in contrast to the side wrinkle unit 71 the rollers 700 of the longitudinal wrinkle unit 70 may comprise edges 701 and rails 702 on the surface of the wrinkle rollers which are arranged as this is schematically shown in the upper left representation of the Figure 3. The lower left representation shows an alternative arrangement of edges 701 and rails 702, however, although the peaks are shown having an acute contour they can be rounded. As the sheet material 2 passes through the pair of rollers 700 it is wrinkled in the longitudinal direction, that is, in the direction of transport of the sheet material 2. In the left representations of Figure 3, the sheet material 2 passes outside the plane of the drawings in the direction of the observer.
    [0044] [0044] Of course, the apparatus may also comprise both a longitudinal wrinkle unit 70 and a lateral wrinkle unit 71. This results in a pattern of longitudinally and transversely arranged recesses in the sheet material.
    [0045] [0045] Subsequently, the sheet material passes through the application unit 8 where the particulate or liquid supplement material, preferably a particulate matter, is added to the corrugated sheet material 2. The particulate material can be applied within the corrugated grooves in the sheet material 2 by the ridges 711 or 701 of the rollers 71 or 70, or within the recesses, respectively.
    [0046] [0046] The sheet material to which the particulate material has been added can then be pulled through a converging funnel to form a bar of compressed sheet material containing the particulate matter. This bar of compressed sheet material can then be processed by a filter making apparatus in the conventional manner.
