  The diameter of the cavity in the center of this coreless toilet paper is reduced, and the part around the cavity with a small diameter in the center corresponds to the beginning of the paper winding. By adhering in the form of a mist, several layers facing the cavity are bonded to each other, and by the adhesion, the several layers facing the cavity are solidified and serve as the core of the cardboard of ordinary toilet paper.

  Therefore, after using it even in the coreless toilet paper, a cylindrical part solidified with moisture remains over several layers around the central cavity, and the solid cylindrical part is disposed of separately. There is an inconvenience of having to.

  As shown in FIG. 11, the problem to be solved by the present invention is that a support rod 15 is inserted into the central cavity of a conventional coreless toilet paper so that the center of rotation of the coreless toilet paper is inserted. Although used as a body, when the paper is used up, the several layers 16 of the paper around the support rod 15 are solidified with moisture. For example, the state shown in FIG. ) In the end, the portion A is pulled with a finger. As shown by Z, the paper A breaks along the way, and the last solid cylindrical portion remains around the support rod 15, and the remaining portion. There is a drawback that it must be pulled out one by one and disposed of separately.

The coreless toilet paper of the present invention comprises a cylindrical hollow formed at the center of the coreless toilet paper, which is composed of a portion wound several layers in a state where the winding start end of the paper is folded back , and the folded end of the paper The coreless toilet paper consists of coreless toilet paper that is formed by winding water and applying moisture to several layers of the wound part except for the part. On the rotating roll, and the end of the paper is partially folded on the winding shaft, and then the folded portion and the subsequent paper in contact therewith are wound together on the winding shaft, and the folded end is removed. A core that removes the take-up shaft after applying moisture to several layers of the take-up part, winding the desired length on the take-up shaft, cutting and gluing the cut end No toilet paper Consisting of production method.

Furthermore, an apparatus for carrying out such a method has a take-up shaft for toilet paper disposed between a first rotary roll and a second rotary roll, and a presser roll that can be freely contacted and separated is provided on the take-up shaft. The toilet paper that has been wound on the winding shaft is provided with moisture applying means for applying moisture to several layers of the wound portion except for the folded end , and further wound on the winding shaft. Further, the present invention comprises a coreless toilet paper manufacturing apparatus provided with toilet paper cutting means and gluing means.
In addition, the toilet paper folding means used in such a device comprises an apparatus using an air nozzle directed to the toilet paper and a toilet paper suction box on the opposite side.

  1. In the coreless toilet paper of the present invention, the cylindrical portion solidified with moisture remaining at the end of its use can be removed together with the final paper by simply pulling the remaining paper with a finger. There is no inconvenience of removing the shaped part separately.

  2. In the method of manufacturing the coreless toilet paper according to the present invention, when the paper is started to be wound around the winding shaft, the winding start portion is simply rewound and then the remaining paper is wound around the winding shaft. At the end of use, the entire remainder of the coreless toilet paper can be removed cleanly completely and easily.

  3. Since the apparatus of the present invention can be rewound once at the beginning of winding of the coreless toilet paper, it can be performed simply by using an air nozzle and a paper suction box, so that the apparatus can be made simply and inexpensively.

  A method of manufacturing the coreless toilet paper of the present invention and an apparatus for carrying out the method are as follows.

  In FIG. 1, first, wide toilet paper A (hereinafter simply referred to as “paper A”) is supplied onto the first rotating roll 1 from the direction of the arrow, and then the paper A is passed through the lower side of the winding shaft 4 onto the second rotating roll 2. Led.

  In this state, as shown in FIG. 2, when air is ejected from the front lower side of the leading end surface of the paper A by the paper folding air nozzle 8, the paper A is folded up around the winding shaft 4. This folded portion is indicated by A ′. Next, as shown in FIG. 3, the paper A ′ is sucked into the paper suction box 10 by evacuating the paper suction box 10 to suck the paper A ′.

  When the length of the paper A ′ sucked into the paper suction box 10 is appropriately sucked until the length becomes equal to or longer than one circumference of the outer periphery of the winding shaft 4, the suction is stopped. Then, as shown in FIG. 4, the presser roll 3 is lowered and the winding shaft 4 is pressed by the presser roll 3 together with the first and second rotating rolls 1 and 2. In this state, the paper presser cylinder 9 is lowered, and the paper presser plate 12 attached to the tip of the paper presser cylinder 12 is lowered together. As shown in FIG. 9, the surface of the folded portion X of the paper A ′ is taken up from above. The paper A ′ is inserted into the X-ray where the first rotating roll 1 and the winding shaft 4 are in contact with each other.

  Next, as shown in FIG. 5, the paper presser plate 12 is raised together with the paper presser cylinder 9. Then, the first and second rotating rolls 1 and 2 and the presser roll 3 start to rotate in earnest as indicated by the arrows shown in FIG. 5, and water is sprayed onto the folded portion of the paper by the spray gun 7. By this spraying, the portion close to the winding shaft 4 side of the paper A ′ portion corresponding to the winding start portion in FIG.

  Therefore, the initial portion where the papers A and A 'are wound on the winding shaft 4 is generally hardened for several layers, and the hardened hollow portion serves as a role of a hollow cylindrical core of cardboard in ordinary toilet paper. Is fulfilled.

  In the present invention, the hardened cylindrical cylindrical layers are hereinafter referred to as an inner solidified layer. When this inner solidified layer is formed, the spray A is stopped and the paper A is wound up to a predetermined thickness on the winding shaft 4 in the state shown in FIG. As shown in FIG. 7, when the winding of the paper onto the winding shaft 4 is completed, as shown in FIG. 8, the paper roll P, which has been wound by raising the presser roll 3, falls down obliquely downward, and the discharge cylinder 11 is fixed. Therefore, the end of the paper A is cut by the cutter 5, and at the same time, the cut end of the paper A is glued and the glue is sprayed by the glue gun 6 to attach the end of the paper A.

  Thus, the paper roll P is finally discharged in the direction of the arrow by raising the paper roll discharge cylinder 11, and finally the winding shaft is extracted from the center of the paper roll P.

  The coreless toilet paper of the present invention is completed by the above method and apparatus. The winding start portion around the winding shaft, which is a feature of the coreless toilet paper of the present invention, will be further described with reference to FIGS.

  FIG. 9 shows a state in which the paper A ′ on the winding start side of the paper A is folded back on the winding shaft 4 in the factory. FIG. 10 shows a state where the user finally left the toilet using the coreless toilet paper A in the toilet, and 17 shows the inside of the central cavity of the coreless toilet paper. The support rods 17 are inserted into the support rod 17, and the water around the support rods 17 is spread several times around the support rods 17, so that several layers around the support rods 17 are formed. A solid state, that is, an inner solidified layer is formed. If there is no folded portion A 'in FIG. 10, the portion D of the paper A consisting of only one sheet is finally held by the finger and pulled in the direction of the arrow. Therefore, it breaks at the breaking line T, and all the remaining inner solidified layer remains around the support rod 17.

  However, according to the present invention, as shown in FIG. 10, since there is a folded paper A ′, the portion S is composed of two sheets, a lower paper A and an upper paper A ′. If you pull the part of S that is two as shown by the arrow, you will pull the two together, and the tensile strength will be twice that of one, so the back side around the support rod 17 Breaking at the breaking line Y, the solid cylindrical body around the support bar 17, that is, the inner solidified layer is torn off together with the papers A and A ′, and no paper remains on the support bar 17. Thus, the object of the present invention can be achieved.
