Abstract

The conventional toilet roll paper is wound so that the concave curled surface is positioned on the inner surface side of the product roll as the paper property of the base paper, so that the winding end of the base paper is in close contact with the outer surface of the roll. Difficult to identify. In a toilet roll paper formed by winding a small roll 5 having a product diameter from a large roll 4 manufactured by a paper making apparatus 1 and then cutting the small roll 5 for each product length, a base paper is used. As a property of the paper in S, winding is performed so that the concavely curled surface a appears on the outer surface side of the product roll 6, so that the winding end Sa of the base paper S is naturally separated from the roll outer surface Ra. Curling is performed (when unwrapping the base paper, the base paper winding end Sa is easily identified and the base paper winding end Sa is easily picked with a finger). [Selection] Figure 9

Description

  The present invention relates to toilet roll paper and a method for producing the toilet roll paper.

  The conventional toilet roll paper shown in FIG. 6 is manufactured as follows.

  First, the papermaking apparatus 1 shown in FIG. 1 is used to discharge the raw material liquid (pulp liquid) to the outer surface of the papermaking net (circular net in the illustrated example) 11 so that the raw paper component is indicated by the dotted arrow S1. Adhering to the outer surface → Transfer the base paper component (S1) to the first felt 12 side as indicated by the dotted arrow S2 → Transfer the base paper component (S2) on the first felt 12 closer to the first felt end At the position, it is transferred to the second felt 13 side as shown by the dotted arrow S3 → The base paper component (S3) on the second felt 13 is transferred to the outer surface of the dryer roll 14 and dried as shown by the dotted arrow S4 → The base paper S transported along the outer surface of the dryer roll 14 is peeled off from the outer surface of the dryer roll by the doctor blade 15, and the base paper S is sequentially wound to form the large-diameter roll paper 4.

  In the base paper S wound up on the large-diameter roll paper 4, the surface in contact with the outer surface of the papermaking net 11 (FIG. 1) in the papermaking process is the back surface a, and the opposite surface is the surface b. 1, the back surface a of the base paper component S1 that has been in contact with the outer surface of the papermaking net 11 is positioned on the inner surface side of the large-diameter roll paper 4 when being wound on the large-diameter roll paper 4. To come. In other words, the surface b of the base paper S appears on the outer surface side of the large-diameter roll paper 4.

  Next, the base paper S of the large diameter roll paper 4 manufactured in FIG. 1 is wound around the small roll 5A having the product diameter by the winding roll portion 21 of the winder 2 as shown in FIG. Winding is performed so that the surface b of the base paper S fed out from the roll paper 4 appears as it is on the outer surface of the small roll 5A. The small roll 5A grown to the product diameter by the winding roll unit 21 is discharged from the winding roll unit 21 as indicated by reference numeral 5A ', and the base paper S continuous with the small winding roll 5A'. After cutting with a cutter 22, tail processing (gluing) is performed.

  By the way, as shown in FIG. 2, when the winder 2 winds from the large-diameter roll paper 4 to the small roll 5A, it takes up almost air between the base papers S that are superposed in the radial direction because they are wound with tension applied. Are wound in close contact with each other without being interposed.

  Next, as shown in FIG. 3, the small roll 5A is sequentially cut by the product length with the disk cutter 31 of the roll cutting machine 3 to obtain a product roll (toilet roll paper) 6A. Note that the toilet roll paper 6A shown in FIG. 6 has an outer diameter of about 110 to 120 mm and a length of about 114 mm. When the per-winding length is about 150 m), the degree of adhesion between the base papers to be polymerized becomes very high.

  By the way, in the paper making apparatus 1 of FIG. 1, when the base paper S dried by the dryer roll 14 is peeled off from the outer surface of the dryer roll by the doctor blade 15, as shown in an enlarged view in FIG. Concavity and convexity processing Sb is performed. The crepe-like minute unevenness processing Sb is a fine one that cannot be identified with the naked eye, but a large number of arc-shaped convex portions are formed on the surface b side of the base paper S (the side to be peeled off by the doctor blade 15). Yes.

  As shown in FIG. 5, the base paper S on which the crepe-like micro unevenness processing Sb is applied has a convex surface on the side peeled off by the doctor blade 15 (FIG. 4) as shown in FIG. 5. Has a characteristic of curling (curving). In addition, that the surface b side of the base paper S is convex has the same meaning as that the back surface a side of the base paper S is concave.

  In the conventional toilet roll paper 6A (FIG. 6), when the large diameter roll paper 4 is wound onto the small roll 5A as shown in FIG. 2, the back surface a of the base paper S is the small roll 5A (or 5A ′). In this case, in the product roll 6A of FIG. 6 in which the small roll 5A is cut into product dimensions as shown in FIG. Since there is a property of curling so as to be concave (see FIG. 5), the winding end Sa of the base paper S located on the outermost side is bonded to the outer surface Ra of the roll R in close contact as shown in FIGS. become.

  By the way, as shown in FIG. 6, with the product roll (toilet roll paper) 6A set in the roll holder 7, the winding end Sa of the base paper S located on the outermost side is the outer surface Ra of the roll R as shown in FIG. In this case, since the winding end Sa and the base paper S are the same color and the base paper S is extremely thin (a step is unlikely to appear), the position of the winding end Sa can be identified visually. In addition to having a hard time, it is very troublesome to pick only the winding end Sa with a finger.

  That is, in the conventional toilet roll paper 6A shown in FIG. 6 and FIG. 7, it is wound so that the back surface a of the base paper S (the surface opposite to the surface peeled by the doctor blade 15 (surface b)) is the inner surface side of the roll. The winding end Sa of the base paper S is in close contact with the outer surface Ra of the roll R because it is curled so that the back side a of the base paper is concave (see FIG. 5). Then, it becomes difficult to identify the winding end Sa, and if the position of the winding end Sa is lost, it is necessary to rotate the product roll 6A to search for the winding end Sa. Even when trying to pick Sa with a finger, it is very difficult to pick, and sometimes the base paper S under the winding end Sa is also picked at the same time and the base paper S underneath is broken.

  Therefore, the present invention relates to a toilet roll paper formed by winding a small roll of product diameter from a large roll paper manufactured by a papermaking apparatus, and then cutting the small roll for each product length. The purpose of the present invention is to provide a toilet roll paper and a method for manufacturing the same, in which the winding end can be clearly identified.

Then, the toilet roll paper (product roll) 6 formed by cutting the small roll 5 for each product length is intended. In the description of the present application, the toilet roll paper 6 and the product roll 6 are the same.

  The toilet roll paper 6 according to claim 1 is characterized in that the paper a in the base paper S is wound so that the surface a on the concave curling side appears on the outer surface side of the product roll 6.

  In the first aspect of the invention, as described in the background section above, the back surface a of the base paper S (the surface opposite to the surface where the doctor blade 15 contacts in the dryer roll 14) during the production of the large-diameter roll paper is provided. Using the property of curling so as to be concave, the winding end Sa of the base paper S is rolled as shown in FIGS. 9 and 10 by winding the base paper back surface a so that it appears on the outer surface side of the product roll 6. The outer surface Ra is curled outward.

  In this way, when the winding end Sa of the base paper S is curled outward, the winding end Sa is separated from the roll outer surface Ra, so that the winding end Sa can be easily identified, and when the base paper S is unwound, It becomes easy to pick only the winding end Sa with a finger.
