Definitions
- the present invention relates to a method for manufacturing an absorbent article having a predetermined pattern at a predetermined position.
- Absorbent articles such as disposable diapers may be provided with a predetermined pattern at a predetermined position for the purpose of facilitating discrimination between before and after.
- a predetermined pattern For example, children's pants-type diapers manufactured by the side-by-side processing method have a pattern that is continuous in the width direction on the back, or the center of the back, for distinction between front and back. Some have a one-point pattern. Colored elastic members at the waist and markings or colored yarns attached to the waist are also used. Printed patterns have also become popular with mothers and children. For example, animal paintings, vehicles, characters, and food are often used as patterns for children's diapers. As a technique for continuously producing disposable diapers, there is a technique described in US Pat. No. 5,045,135. Japanese Patent No.
- 2616999 describes a technique for forming a pattern on a diaper.
- an inline printing machine is arranged in the middle of a production line, and a pattern is printed in a line on a material for forming an absorbent article such as a leak-proof sheet.
- a technique for disposing a printed forming material at a predetermined position on an absorbent article is known.
- the production line is easily contaminated, and if there are multiple production lines, a printing machine is required for each production line, increasing the cost associated with pattern printing.
- that number of plates and printing equipment is required, which requires days to introduce the equipment, and the printing equipment is expensive.
- the printing pitch changes when the sheet is fed from the wound roll. Therefore, when a pattern is to be applied to an absorbent article using such a sheet, the change in the printing pitch at the time of feeding the sheet is corrected, and the printing position of the sheet is arranged at a predetermined position on the absorbent article. You have to make it happen. In other words, since the printing pitch of the fed-out sheet varies, it is necessary to change the feeding amount of the sheet by speeding up or slowing down the sheet feeding. However, if the sheet is fed out at that time, the sheet tension becomes zero, and the sheet sags and the sheet (vertical, horizontal, diagonal) occurs, and the sheet meanders. Making the seat tension free led to product defects and problems on the production line. That is, conventionally, it has been extremely difficult to attach a positioned pattern to a predetermined position of an absorbent article using a sheet on which a preliminary pattern is printed. Disclosure of the invention
