Document Type and Number:
WIPO Patent Application WO/2019/150802
Kind Code:
A1
Abstract:
A production method of an elastic composite sheet is provided which makes it possible for the elastic member not to break when the elastic member, in a stretched state, is bonded to a base material sheet; an elastic composite sheet and a disposable wearable article using said elastic composite sheet are also provided. A strip-shape or linear-shape elastic member (3) composed mainly of a thermoplastic elastic resin is stretched in the longitudinal direction of the elastic member (3). The stretched elastic member (3) is placed over a first base material sheet (4) such that the main surface of the first base material sheet (4) contacts the elastic member (3). In a state in which the stretched elastic member (3) and the first base material sheet (4) are placed over each other, the elastic member (3) and the first base material sheet (4) are bonded in a first position (60) that overlaps the elastic member (3) seen from a direction perpendicular to the main surface of the first base material sheet (4) and that is away from the edges (3p, 3q) of the elastic member (3).
