    A coreless toilet paper roll having a center hole with alternate radial corners and inwardly bulged portions is manufactured by winding toilet paper on a winding shaft having a polygonal or gear-shaped section to form a roll on the winding shaft and then extracting the winding shaft from the rod. The center hole produced in this way is rigid and safe from collapse. The corners or gear teeth of the winding shaft may be arranged helically on the winding shaft to avoid noise during the winding. The toilet paper may be moistened at the outset of winding to provide a more rigid center hole.

    The invention relates to a sleeveless roll of toilet paper, and the method of its manufacture and can be used in the paper and printing industry.
    The purpose of the invention is to reduce costs and improve usability.

    The special features of making toilet rolls are as follows. The roll 1 has a central opening (Fig. 1) of approximately the shape of an asterisk and the size is large enough for it to be inserted into it. It is possible to insert a toilet tissue holder rod or similar means.
    A sheet of toilet paper P is wound onto a non-circular (in the form of a polygon or gear) winding roller 3 installed in a winding | Toilet paper machine. By rotating the winding roller 3 together with the pressure roller 4 which is pressed against it, a

    a roll of toilet paper with the required number of turns (fig.Z). In this case, the molding in the roll of the central hole 2 is carried out in two stages: at the preliminary stage during the winding process under pressure of paper on the roller 3 and at the subsequent stage, when the winding roller 3 is removed from the roll of toilet paper, which is then cut into small rolls devices.
    The load on the toilet paper is wound while winding it onto the roller 3 is constant from the beginning to the end of the winding. The load can be gradually or stepwise lowered as the roll roll diameter increases. When the winding roller with a cross section, for example, in the form of a regular hexagon, is removed from the toilet roll at the end of the winding, the remaining central opening is immediately narrowed and stabilized by a force that
    5 the paper of this roll is obtained by winding under load. Under the action of this force, the parts of the roll are displaced to the center (by the action of centrifugal force) so that the inner surface of the central hole -, with the exception of the corner parts 5 (constrictions) formed by the corners of the outer surface of the winding shaft 3, is narrowed. sections 6, corresponding to the sides 7 of the roller 3, form arched protrusions inside the central hole. As a result, the hole 2 is securely maintained. In such a roll of toilet paper radius R |,
    0 coming from the top of each corner section 8 of the winding roller 3 to the outer surface of the coil, less than the radius К „, which goes from each side 7 of the winding roller to the external
    g roll circumference. Therefore, since the number of layers of paper is the same for radii R and R, the density of paper along radius R. | higher density radius RQ. Thus, a portion of the inner circumference of the toilet paper when winding the latter onto the winding roller is cut through each corner 8 of the winding roller 3, which makes it possible to obtain corner sections 5. When the winding roller 3 is removed from the roll, the corner sections 5 retain their position and each side 6 formed by the side 7 of the winding roller and having a multilayer flue 5

    The winding capacity, under the action of the centrifugal force of the coil, protrudes inside the hole. The result is a central hole 2 of the roll I, having the shape of an asterisk.
    When, for example, for manufacturing a roll, a steel winding roller 3 with a cross section of a regular hexagon and with a distance of 20 mm between opposite corners and 17 mm between opposite sides is used, the length between the dry sections 5 of central hole 2 of roll I is about 15 mm, that only 25% less than the diagonal distance of 20 mm of the winding roller, and the distance between the projecting tops of the sides 6 is approximately 8-9 mm, which is 50% less than the distance of 17 mm between the opposite sides of the winding th roller.
    After that, when cutting small rolls from a toilet roll using a cutting device, the opening 2 does not collapse under the action of the cutting edge force when passing its high density section in the constrictions 5. The deformation is so small that a 10 mm diameter axis can be easily inserted into the opening allowing the roll to be mounted in the holder rotatably. If one or both ends of the round rod is made of a smaller diameter to facilitate its installation into the hole, then a rod with a diameter of 14 mm can be used, i.e. opening 2 expands slightly outward.
    On the outer circumference of a round steel bar with a diameter of 20 mm (Fig. 5), eight circumferential grooves with a depth of 2 mm and a width of 5.5 mm are formed. They are located at the same distance from one another (about 2 mm), therefore the winding roller 3 resembles a gear wheel in the shape of its cross section. After winding, the winding roller is removed, and the resulting roll is cut into small rolls with a cutting device. The winding load can be kept constant from start to finish in the usual way, or it can be gradually or stepwise reduced as the diameter increases.

    In addition, in this case, the radius R., going from the top 9 between the grooves 10 to the outer surface of the toilet roll, is somewhat less than the radius R going from the surface of the groove 10 to the outer periphery and the paper density is up to the corresponding value. The inner circumference of the toilet paper under pressure sits on the tops 9 of the outer circumference of the winding roller during winding onto the latter, and the portions 11 in contact with the vertices 9 are radially pushed in to obtain a toothed profile which the roller 3 has. the pressure that shrinks mainly the portions 13 in contact with the grooves of the winding roller. These areas appear to be protruding into the interior of the aperture. After removing the winding roller, the diagonal distance between the sections 11, which have received a radial gear profile, is approximately 16 mm, which is 20% smaller than the diameter (20 mm) of the winding roller, while the distance between the tops of the convex sections 13 is 12 mm, which is less by 40%. When a roll of toilet paper is cut by a cutting machine into small rolls, the hole 12 is not deformed by the force of the cutting edge in section 11, which has a high density. Thus, in view of the fact that the deformation is not significant, a round roller with a diameter of up to 12 mm can be easily inserted into the hole and then the roll can be installed in the holder rotatably.
    Section 11, having a serrated profile (figure 4), is located between the inward-opening holes 13 and at some distance from the adjacent sections 13, whereas in the variant shown in figure 1, the section 6 convex inwards presses on the part of the narrowed section 5, previously in contact with the angle of the winding roller. The central hole formed by the convex portions (FIG. 1) is less deformed than the hole in FIG. 4,
    The method of making toilet roll (Fig. 2) is commonly referred to as an axial drive system. In addition to this method, there are also so-called surface drive systems. One of the surface drive systems consists of a winding roller 3 located between a pair of rollers 14 (FIG. 9). Another system involves the use of a winding roller 3 located between the conveyor belts 15 installed in the form of a letter V or the letter X (figure 10). In any case, the presser roller 4 runs along the winding roller, ensuring that the toilet paper is wound onto the winding roller with a given winding density. The pressure exerted by the pressure roller 4 may correspond to the pressure created by its own weight, or the pressure of its own weight plus the pressure of the additional weight or force generated by the piston. The pressure roller, in direct contact with the winding roller, is located on top of the latter, in the initial stage of winding. When the toilet paper is being wound onto a roller, the pressure roller contacts the winding through the wound toilet paper and gradually rises as the volume of the wound toilet paper increases,
    The winding roller may have a polygonal cross-section similar to a gear-wheel. When the corner sections corresponding to the wheel teeth are parallel to the axis of the winding roller, the pressure roller bounces on the winding roller due to the non-cylindrical configuration of the latter, until a sufficient amount of paper is wound on the winding roller and it takes approximately the shape of a cylinder. In the case of using a surface drive system, there is not a pressure roller, but the winding roller itself bounces on rollers 14 or belts 15. As a result, the required winding density of toilet paper is obtained, in addition, the winding roller is offset from the center, as a result of which the central hole formed extracting the winding roller, located eccentrically. In addition, it may happen that the toilet paper breaks in its width when wound, resulting in its loss of m.
    To eliminate these drawbacks, a design is used in which the corners of the polygonal winding roller are located — along an in-line line in the axis

    direction. As a result, bouncing of the pressure or winding rollers is minimized (Figures I1 and 12).
    A winding roller having a polygonal cross section is made as follows: o6pa3OHf
    A length of paper is wound onto the winding portion 16. From each end of the winding part 16, a cylindrical axis 17 departs. In the case of using an axial drive system, one or both axes 17 are installed with the possibility of removal in bearings of the winding machine, which is associated with a rotational movement. If a surface drive system is used, the axis 17 is installed in the winding machine so that the roller can move up from the roller 14 or the tape 15 during winding and one or both ends can be removed from the winding machine.
    In terms of cross-sectional shape, the winding part 16 used in this case is a regular hexagon, and its every angle 18 is shifted by 90 ° between one 19 and OTHER 20 ends of the winding part, i.e. each angle 18 is located in a helix with a step of 1/4. The step of spacing is not limited to 1/4 relative to the full length of the winding part, but it is preferable to use a step of 360 ° / n, where n is the number of angles, so that the pressure roller is constantly supported On a part of one of the corners and in the case of using a self-propelling machine using a surface drive system, the winding roller could constantly come into contact with the roller 14 or tape 15 in a part of one of the corners. If, for example, the winding part is a regular polygon in cross section, then the pitch is 60 or 1/6. The pitch can be made smaller (60 °). For example, in the case of a regular octagon, a step of 45 or 1/8 would be sufficient, since the degree of jumping is much smaller compared with the corresponding indicator in known devices in which the angle is parallel to the axis.
    In the case of using a winding roller (Figures 13 and 14), in which the winding part has a cross section in the form of a gear wheel, there are twelve teeth (or grooves are arranged spirally around the entire circumference and at an equal distance from each other in 1/6 steps, which twice the magnitude of ZbO ° / 12 30 ° 1/12.
    The most preferred step is two or three times larger than the step indicated, since in the STOM case the pressure roller is in constant contact with a variety of angles, which allows for winding similar to the winding performed when using a winding roller with a cylindrical outer surface, as a result, bounce of the pressure roller is eliminated (bounce of the winding roller in the case of using a surface drive system).
    In addition, the described drawbacks can be eliminated by minimizing the degree of bouncing during
    According to the proposed method, toilet paper is wound onto a wet roller with a cross section in the form of a polygon or a gear wheel, after winding the winding roller is removed from the roll, a toilet paper roll with a central hole in the shape of an asterisk is obtained. In order to prevent the central hole of its configuration from losing its central hole, toilet paper is moistened, water or an aqueous solution containing a small concentration of an adhesive, such as a paste, is applied to it at the initial winding stage. alkaline cellulose (CMC - carboxymethylcellulose) and other material or winding rollers in the initial stage of winding or by welding.

At the same time, the inner circumference of the wound toilet paper is given the appearance of angles or grooves directed along the helix, and thus, when the winding roller is removed, the portions between the corners or teeth that preserve the resulting configuration circle roll.
    When removing the winding roller, it is necessary to pull it out, rotating it along spiral protrusions formed by the corners or teeth. In this connection, the pitch of the helix is determined taking into account the number of revolutions required

    In the case of using a wetting device (Figs. 15 and 16), the winding roller 3 rolls between the drive rollers 14 and rotates from frictional contact with the latter when pressed upwards by the welding roller 4 in the process of winding a piece of toilet paper P with the required density using for this purpose - own weight of the pressure roller, any additional weight or if necessary

    Directly under the gap between the two PV1 rollers 14, an upwardly directed nozzle 21 is disposed for spraying water or an aqueous solution in the direction of the toilet paper P in the initial stage of winding. Due to this spraying, the moisture content in the moistened areas increases by 5-7% to 25-35% compared with the previous dry condition.
    It is enough to moisten the first coil or the first few coils of toilet paper or moisten one or several coils after the first one or several coils. The spraying can be controlled by adjusting the operation of the nozzle 21 using a time switch or by turning on the winding switch. Water or water solution is sprayed through a nozzle for a few seconds immediately or a few seconds after the switch is turned on.
    For winding 65m of toilet paper, it takes about 15-20 seconds, during which part of the water applied at the beginning of the winding is absorbed by layers of dry paper adjacent to OTHER, slightly wetting the inner peripheral area 22 of the wound paper (at the end of winding the water content is em 15-20%). The inner peripheral area 22 is compacted around the outer peripheral surface of the winding roller with subsequent turns of toilet paper applied outside the inner peripheral area.
    After the winding roller has been removed upon completion of the winding, the angle 23 remains the same as on the inner peripheral zone of the wound boom layer.
    g, and a roll of toilet paper is formed, (Fig. 17), in which section 24, g is a more efficient means, located between the corners 23, of the projection, in which it is used, inside the opening. Fig. 17 shows a dash-dotted line of the cross section of the winding roller to show the change in the inner peripheral zone that occurred before and after removing the winding roller.
    If the toilet paper is not moistened at the beginning of the winding, then the contours are wired-gg with a pressure roller 4. Namotochny
    After removal of the winding roller, the changes are insignificant. However, due to the fact that the inner periphery of the zoo roll and toilet roll is brought into one-way rotational motion by two endless ribbons. Before the upper end of the single tape forming the chute is located

    the magicians are dry; the fibers that make up toilet paper retain their elasticity, as a result of which the angle is less pronounced than in the case when it is moisturized. When the inner peripheral zone is moistened, the fibers lose their elasticity, acquiring the expected configuration in the form of a clearly defined angle. After the winding roller has been removed, air flows through the hole to the paper, while the angle is still clearly defined.
    When cutting a roll of toilet paper into shorter rolls using a cutting device, the corners on the inner peripheral part retain their shape and, therefore, withstand the pressure force generated when the cutting device is inserted, and as a result, no the ferian part would be destroyed. At the same time, the inner peripheral part is not destroyed even by the shocks it experiences when packing products into corrugated cardboard boxes, placed one on top of another, in order to prevent damage to the boxes. The water content in the inner peripheral part is about 15-20% at the end of the winding and 10-12% after the roll is cut into small rolls after about 10-15 minutes after removing the winding roller, which is performed immediately after the end of the winding.
    When an aqueous solution of a small concentration glue is used instead of water for moistening, the inner peripheral part hardens as it dries out, thus such a solution

    with a humidifying device (Fig. 18), as well as a surface drive system, i.e. The machine shown in gQ of FIG. 10, two sets of narrow endless conveyor belts 15 are arranged crosswise in the form of an X, and the flow roller is located in the groove formed by two belts and holds the roller in one-sided rotational motion by two endless belts. In front of the upper end of the single belt forming the groove is located
    a dampening roller 25 for applying water or a similar liquid in the form of longitudinal strips on toilet paper moving downward into a chute. There is also a liquid supply device, in which water or other liquid is applied to the outer surface of the moistening roller by means of a liquid supply roller 26, which is half immersed in a bath of water or similar liquid. The device at the initial stage of winding for a short period of time is lifted upwards with the help of a cylinder, water or other liquid is applied to toilet paper with a roller 25, forming water strips 27 (Fig. 19), and after a certain period of time the cylinder is retracted downwards and the device is removed out of contact with toilet paper.
    The amount of water used to form the water strips, the width of the strips and the intermediate distance between the strips are calculated so that the paper web is wetted over the entire width as the strips move down in the groove and winding on the winding roller, and it is necessary to ensure that no breakage occurs. toilet paper width before winding strips on the winding roller.
    In the process of winding water or other liquid applied at the beginning of 40
    penetrates into the adjacent layers which will be relatively large
    for example more than 25 mm.
    It follows from this that it agrees. The method of making a roll of toilet paper by removing the winding roller at the end of the winding creates an opening into which a rod can be easily inserted to place the roll in the holder. In addition, the resulting roll of toilet paper in 4g generally corresponds to the conventional concept of a roll of toilet paper with a hole in the center. Moreover, the shape of this hole is not just a circle, its

    As the result is a slightly moistened inner peripheral part, as a result, a well-defined angle is formed on the inner peripheral surface, which lies opposite the angle on the outer surface of the winding roller. After removing the winding roller, this angle retains its configuration due to which there is no destruction of the inner peripheral part.
    Since the working part of the winding shaft in cross section has the shape of a gear wheel with teeth,
    Depending on the similarly described variants of the cross-section of the coiler, they can be made with the use of a roller. Thus, the hole itself is a decorative element.
    Since they do not use a tubular eg paper sleeve, articles can be manufactured at a cost that is less than the cost of the sleeve. After the paper is used up, nothing is left; as a result, the possibility of
    polygonal cross section.
    The moistening device (Fig. 20) contains a moistening roller 25, a roller 26, subRands of a liquid and other parts (Fig. 18) instead of the nozzle 21 (Fig. 16). The moistening roller 25 is positioned so that it can come into contact with one of 369670 2
    drive rollers 14. A cylinder is activated for an appropriate period of time to put the dampening roller 25 in contact with the drive 14 in order to supply the necessary amount of water to toilet paper P through the roller 14. A similar effect can be obtained and
    Q in the case of the options presented on Fig and 18.
    In structures using wetting devices, the number of corners of the winding roller polygon and
    15, the number of gear teeth, the shape of which has a cross section of the winding roller, is selected depending on the size of the outer diameter of the winding roller. For example,
    20 to create an inner peripheral portion with an average inner diameter greater than 25 mm, the number of corners or the number of teeth must exceed 10, i.e. equal to 12-16.
    25 In the case of a slight moistening of the toilet paper, carried out during winding, the corners formed by the corners of the outer surface of the winding
    the roller can be formed in the central opening of the roll to maintain the configuration of the inner peripheral part, it is even possible to create such a central opening, the average internal diameter
