Document Type and Number:
Japanese Patent JP6902997
Kind Code:
B2
Abstract:
To suppress a difference in engagement strength of a pair of joint parts when forming the pair of joint parts by overlapping and fusing an abdominal side continuous part and a back side continuous part.SOLUTION: A manufacturing method includes: forming a continuous body of a precursor 1b of an absorbent article 1 by overlapping, while conveying in a conveyance direction a continuous sheet member 101a having an abdominal side continuous part 111 and a back side continuous part 113 at both sides in a transverse direction, the abdominal side continuous part on the back side continuous part; and forming a pair of joint parts 14a,14b by fusing an upstream side end part of a downstream side precursor of adjacent two precursors by a downstream side projection of a first holding member 92 and a second holding member 91, and fusing a downstream side end part of an upstream side precursor by an upstream projection of the first holding member and the second holding member. The pair of joint parts are asymmetrical. The joint part of the upstream side end part includes a temporarily fastening fusion part 21Da at a downstream side, and an actual fastening fusion part 21Db at an upstream side. The joint part of the downstream side end part includes an actual fusion part 21Ub. An area of the temporarily fastening fusion part is smaller than that of the actual fastening fusion part.SELECTED DRAWING: Figure 3
