A method comprising a step of manufacturing an elastic laminated body by laminating two webs and while inserting an elastic member in an extended state in a web length direction in between; a step of cutting the elastic laminated body in a length direction so that a concave portion and a convex portion appear alternately; a step of attaching a cover sheet to bridge between the concave portion and the convex portion of cut first elastic laminated body and second elastic laminated body, respectively; a step of widening the first elastic laminated body and the second elastic laminated body to which the cover sheet is attached; and a step of attaching an absorber onto the cover sheet, lessens the occurrence of wrinkles and creases produced when webs are cut, and eliminates a problem attributed to the occurrence of wrinkles and arising when an absorber is attached.

Method for manufacturing disposable wearing article

A method includes producing an elastic strip material () by sandwiching an elastic member () between two webs () under a stretched state in the longitudinal direction of the webs (), halving the elastic strip material () in the widthwise direction so that protrusions () and recesses () alternately appear, separating a first elastic strip material and a second elastic strip material obtained by halving in the widthwise direction, shifting the phases of the first and second elastic strip materials in the longitudinal direction so that the protrusions and the recesses become in phase, reducing the shrinking force of the elastic member near the protrusions () of the first and second elastic strip materials (A andB), and attaching an absorber () onto parts () of the first and second elastic strip materials (A) where the shrinking force is reduced.
