Abstract:
1. A method of manufacturing an elastic sheet for an absorbent product which receives excrement from a wearer, the method comprising: positioning an extended first elastic member having a plurality of first elastic yarns along a first direction on a first sheet member; positioning an extended second elastic member having a plurality of second elastic yarns along a second direction tilted relative to the first direction such that the second elastic member crosses the first elastic member at a crossing area and a plurality of intersection points of the plurality of first elastic yarns and the plurality of second elastic yarns are distributed in the crossing area; after said positioning operations, laminating a second sheet member on the first sheet member such that the first elastic member and the second elastic member are interposed between the first sheet member and the second sheet member, and bonding the first sheet member and the second sheet member together; and after said laminating operation, cutting the first elastic member and the second elastic member, together with at least one of the first sheet member and the second sheet member, at the crossing area using cutting blades, wherein the cutting blades include a plurality of first cutting blades tilted relative to the first direction and a plurality of second cutting blades tilted relative to the second direction, wherein said cutting operation includes forming a plurality of cuts in the crossing area with the plurality of first cutting blades and the plurality of second cutting blades, and wherein said cutting operation is performed by making incisions in the sheet members without removing portions of the sheet members.
