Method of manufacturing elastic sheet, and elastic sheet and absorbent product

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 along a first direction on a first sheet member;
• positioning an extended second elastic member 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;
• 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 the first elastic member has a plurality of first elastic yarns along the first direction, the second elastic member has a plurality of second elastic yarns along the second direction, and
• wherein one of the second elastic yarns is disposed directly over one of the first elastic yarns at a crossing point, and the cutting operation includes cutting the second elastic member and the first elastic member at the crossing point.
