METHOD OF MANUFACTURING STANDING GATHER FORMING MEMBER

摘要

A method of making a standing gather-forming member having a basal wall and first and second overhangs on both sides of the basal wall. Elastic members are disposed in their stretched state on the inner surface of a middle portion of a continuously running strip-shaped sheet. One of side portions extending on both longitudinal sides of the middle portion is Z-folded to cover a part of the width of the middle portion thereby to form the first overhang. The other side portion is then folded inward along the longitudinal direction to cover the part of the middle portion that remains uncovered with the first-mentioned side portion and to overlay the Z-folded portion of the first-mentioned side portion thereby to form the second overhang and the basal wall.
