Description

  The present invention relates to a method for manufacturing a toilet paper roll.

  There are two types of sales of toilet paper rolls: one packaged with wrapping paper one by one, and one packaged with a plurality of six, twelve, etc., without being individually wrapped. In recent years, the latter form of sales has increased, and in order to give changes to individual toilet paper rolls, there are also packages that are printed together with different colors and patterns.

  Toilet paper rolls are usually made by winding a wide web of material to a predetermined length and then cutting the rolled log roll into the width of the toilet paper, or by slitting the wide web of web into the width of the toilet paper. After cutting, it is manufactured by a method of winding to a predetermined length, and a plurality of toilet paper rolls are striped from the material web. Some of these toilet paper rolls are usually provided with a perforation line that is a guide for one-time use, and embossed to give unevenness to the entire surface. When printing on a toilet paper roll, a rotary printing machine is provided in the process of winding up the log roll or the toilet paper roll, or a separate printing process including a rotary printing machine is provided.

  As described above, toilet paper rolls manufactured by stripping a plurality of pieces from a wide material web in recent years are often packaged in a bag or the like using an automatic packaging device. Even if such an automatic packaging apparatus is used, the plate cylinder roller of a rotary printing press that prints on the material web is attached to the toilet paper so that toilet paper rolls having different colors and patterns as described above can be packaged together. A method has been proposed in which printing plates with different colors and patterns are arranged in the width direction according to the width of the paper, and toilet paper rolls printed with different colors and patterns are manufactured simultaneously from the same material web. (For example, refer to Patent Document 1). In what is described in Patent Document 1, a rotary printing machine is provided in a process of winding up a log roll or a slit-cut toilet paper roll, and these printings are performed.
