Disposable diaper manufacturing method and disposable diaper

Abstract

The purpose of the present invention is to make the overall manufacturing equipment for pant-type and T-type disposable diapers more compact and to produce diapers efficiently by keeping waste of materials to a minimum. The diaper manufacturing method is characterized in that: a base material sheet (8) obtained from a continuous sheet material (W) and an elastic member (11) is continuously supplied in a feed direction (A); an absorbent body (5) is attached to the base material sheet (W) in the central portion of the width direction; the base material sheet (W) is divided into a pair of waist-encircling sheet portions (9a, 9b) and a single crotch covering sheet portion (10) by two dividing lines (18) along the longitudinal direction of the base material sheet; the crotch covering sheet portion (10) is cut at a prescribed length to form individual crotch coverings (6); the crotch coverings (6) are joined one by one alternately to one or the other waist-encircling sheet portion (9a, 9b); the waist-encircling sheet portions (9a, 9b) are cut at an intermediate position between crotch coverings (6) that are adjacent to each other; the crotch sections (3) are folded in two; and the sections near the two ends of the waist-encircling sections (2) are folded inward and each of said ends is fixed to the free end of the crotch section (3).

Description

technical field [0001] The present invention relates to a method of manufacturing a disposable diaper and the same. Background technique [0002] In general, a disposable diaper includes a waist portion worn around the trunk of a wearer, and a crotch portion fixed to the waist portion. The waist portion includes an elastic member for the body that expands and contracts in the direction of the waist so as to fit the wearer's body. On the other hand, the crotch portion includes an absorber and the like on the inner side (wearer side) of the exterior sheet, and elastic members for leg circumference stretchable along the side edges so as to fit the wearer's legs. [0003] The disposable diaper sometimes fixes one side end of the crotch at the lower central part of a piece of waist extending left and right, and the disposable diaper is formed into a T-shape in an unfolded state (for example, refer to Patent Document 1. Hereinafter referred to as present There is technology 1.)....

AI Technical Summary

Problems solved by technology

Therefore, this prior art 2 cannot be applied to a diaper in which the unfolded state is T-shaped like the prior art 1, and the overall length of the waist portion and the length of the crotch portion are significantly different from each other.
