Method of manufacturing disposable wearing article

Abstract

The invention provides a manufacturing method of a wearing article; the manufacturing method improves the process of continuously manufacturing the disposable wearing article by connecting two side parts by joint parts, thus allowing the shape of the wearing article to be consistent. A pair of linear slots (121) which are extended to the cross direction (CD) and incisions (133) which are respectively crossed with a pair of slots (121) are formed on a composite sheet (103) which is advanced towards the mechanical movement direction (MD) in the manufacturing process of the wearing article (1), and gaps (137) are formed by removing the parts (136) which are surrounded by the slots (121) and the incisions (133) from the composite sheet (103). A pair of first joint parts (116) are arranged on the composite sheet (136) in advance in the process that is before the formation of the gaps (137), then a pair of first joint parts (116) clamp the gaps (137) along the mechanical movement direction (MD) and are opposite, second joint members (124) of joint sheets (123) are fixed on each pair of first joint parts (116), so the joint sheets (123) span the gaps (137) to be arranged on the compositesheet (103).

Description

technical field [0001] The present invention relates to a method of manufacturing a disposable wearing article having engaging components. Background technique [0002] As for the underpants type wearing article which exemplifies a disposable underpants type diaper, there is known a structure in which both side edge parts of front and back waist regions are connected by the detachable and reusable joining member. For example, it is described in WO 01 / 87209A1 (Patent Document 1) as Figure 9 , 10 Disposable training pant 500 and method of manufacture are shown. The underpants 500 have first connecting members 582 on the inner surfaces of both side edge portions of the front waist region 522 , and have second connecting members as mating objects of the first connecting members 582 on the outer surfaces of both side edge portions of the rear waist region 524 . 584. The first connection member 582 uses, for example, a hook-type connector, and the second connection member 584 ...

AI Technical Summary

Problems solved by technology

The base member 532 is in close contact with the endless belt under the action of the vacuum suction pressure, but when a tension is applied to the base member 532 to move to the right side in the figure, there is a gap 579, each front waist region 522 arranged in the direction of mechanical movement may sometimes be misplaced or skewed on the endless belt, so sometimes the shape of the front waist region 522 may not be consistent between the various underpants 500 manufactured continuously.
