Method and device for manufacturing composite element consisting of sheet-like members and adapted for use in absorptive article

Abstract

A method of manufacturing a composite element (1a) consisting of sheet-like members and adapted for use in an absorptive article (10). The method involves causing a first sheet-like member (10) to be held on a holding surface (53) of a holding section (51), and delivering the first sheet-like member (10) from the holding surface (53) to second sheet-like members (20a, 24a) to mount the first sheet-like member (10) on the second sheet-like members (20a, 24a). The first sheet-like member (10) held on the holding surface (53) by suction of air from holes (54) formed in the holding surface (53) has a portion which is, when delivered to the second sheet-like members (20a, 24a), delivered first to the second sheet-like members (20a, 24a) and also has a portion which is delivered next. The holding section (51) is at least provided with two suction chambers (56) which are a first suction chamber (56d) communicating with holes (54) for sucking the portion which is delivered first, and a second suction chamber (56u) communicating with holes (54) for sucking the portion which is delivered next. The first sheet-like member (10) is delivered to the second sheet-like members (20a, 24a) with the first suction chamber (56d) and the second suction chamber (56u) separated from each other such that air cannot communicate between the first and second suction chambers (56d, 56u).

Description

technical field [0001] The present invention relates to a manufacturing method and manufacturing apparatus of a composite of sheet-like members of an absorbent article. Background technique [0002] Conventionally, in the production line of absorbent articles such as disposable diapers and sanitary napkins, the first sheet-like member held on the holding surface of the holding part is transferred from the above-mentioned holding surface to the second sheet-like member for installation, thereby enabling Composites of sheet-like components are produced. [0003] Here, the holding of the first sheet-like member by the holding surface is generally performed by using the suction force generated on the holding surface by sucking air through the plurality of suction holes formed on the holding surface. In addition, these air intake holes communicate with an air intake chamber in which only one area is formed in the holding portion, and air is sucked from the air intake holes in ac...

AI Technical Summary

Problems solved by technology

As a result, the suction force of the suction hole of the above-mentioned remaining part transferred after suction becomes smaller, and the retention of the above-mentioned remaining part before transfer may be reduced.

In addition, due to the decrease in holding performance, deformation of the first sheet-shaped member, etc., may reduce the mounting accuracy of the first sheet-shaped member to the second sheet-shaped member.
