Abstract:
1. A method for manufacturing a pants-type diaper comprising: a diaper body including a front portion covering an abdominal side of a wearer, a back portion covering a back side of the wearer, and a crotch portion between the front portion and the back portion; a side panel connecting together, in a girth direction, a first side edge portion of the front portion and a first side edge portion of the back portion with each other; and another side panel connecting together, in the girth direction, a second side edge portion of the front portion which is away from the first side edge portion thereof in the girth direction and a second side edge portion of the back portion which is away from the first side edge portion thereof in the girth direction, the method comprising: a step of carrying the diaper body in a longitudinal direction perpendicular to the girth direction; a first folding step of folding each of the side panels along a virtual first line extending in the longitudinal direction so that a first portion and a second portion of each of the side panels lie on each other; a first attachment step of attaching a first end portion of each of the side panels in the girth direction to the first and second side edge portions of the front portion or attaching the first end portion of each of the side panels in the girth direction to the first and second side edge portions of the back portion; a second folding step of folding the diaper body along a virtual second line extending along the girth direction so that the front portion and the back portion lie on each other; and a second attachment step of attaching a second end portion of each of the side panels away from the first end portion thereof in the girth direction to the first and second side edge portions of the back portion, to which each of the side panels is unattached in the first attachment step or attaching the second end portion of each of the side panels to the first and second side edge portions of the front portion, to which each of the side panels is unattached in the first attachment step, wherein each of the side panels is folded in the first folding step so that non-skin-contact surfaces thereof face each other; and each of the side panels is attached to the front portion and the back portion in the first and second attachment steps so that at least a portion of each of the side panels between the first end portion and the second end portion is sandwiched between the front portion and the back portion, the method further comprising: a step of placing each of the side panels on the diaper body so that the first and second end portions of each of the side panels folded in the first folding step protrude from each of the side edge portions of the diaper body in the girth direction; a step of folding back the first end portion of each of the side panels so that the first end portion each lies on the first and second side edge portions of a non-skin-contact surface of the diaper body in the girth direction; and a step of folding back the second end portion of each of the side panels so that the second end portion each lies on the first and second side edge portions of the non-skin-contact surface of the diaper body in the girth direction, wherein, after the second folding step of folding the diaper body, the folded-back first end portion is unremovably attached to the non-skin contact surface of the diaper body in the first attachment step and the folded-back second end portion is unremovably attached to the non-skin contact surface of the diaper body in the second attachment step.
