A method for manufacturing an absorbent article, including: while lower bandlike member is transported in a transport direction, a process in which a cutting position is determined, and an adhesion area is formed by putting adhesive on each side of the cutting position of the lower bandlike member in the transport direction; a process in which a plurality of elastic members are placed so that a part of each the elastic members overlaps the adhesion area, the elastic members being stretched in the transport direction; a process in which an upper bandlike member is stacked on the lower bandlike member and the elastic members and the upper bandlike member adheres to the lower bandlike member and the elastic members on the adhesion area; a process in which the lower bandlike member and the upper bandlike member are folded on a center position in an intersecting direction; a process in which the elastic members are cut at a single position between a pair of the adhesion areas which are respectively formed on both sides of the cutting position, and the elastic members contract towards the adhesion area from positions at which the elastic members are cut; a process in which a welded section on which the lower bandlike member and the upper bandlike member are to be welded to each other is formed on each side of the cutting position in the transport direction; and a process in which the lower bandlike member and the upper bandlike member are cut together on the cutting position. |

1. A method for continuously manufacturing an absorbent article,
the absorbent article being a pull-on absorbent article that has a longitudinal direction and a transverse direction intersecting the longitudinal direction, and that includes
a lower exterior member located on a side towards a wearer's garment,an upper exterior member stacked on the lower exterior member from a side towards a wearer's skin,an absorbent main body stacked on the upper exterior member from the side towards a wearer's skin, for absorbing excrement, the method, comprising: while a lower bandlike member and an upper bandlike member are transported in a transport direction that is along the transverse direction, the lower bandlike member including the lower exterior members that continue in a band-like manner in the transverse direction, the upper bandlike member including the upper exterior members that continue in a band-like manner in the transverse direction, a process in which, when the lower exterior member and the upper exterior member are cut and separated from the lower bandlike member and the upper bandlike member, a cutting position is determined, and an adhesion area is formed by putting adhesive on each side of the cutting position in the transport direction, of at least either one of the lower bandlike member and the upper bandlike member, the cutting position being to serve as end sections of the lower exterior member and the upper exterior member in the transverse direction; a process in which a plurality of elastic members are placed so that a part of each of the elastic members overlaps the adhesion area, the elastic members being stretched in the transport direction; a process in which the lower bandlike member and the upper bandlike member are stacked such that the elastic members being sandwiched between the lower and upper bandlike members, and the upper bandlike member adheres to the lower bandlike member and the elastic members on the adhesion area; a process in which the lower bandlike member and the upper bandlike member are folded on a center portion in an intersecting direction so that the upper bandlike member is located inside the lower bandlike member, the intersecting direction intersecting the transport direction; a process in which the elastic members are cut at a single position located between a pair of the adhesion areas, the elastic members being stretched in the transport direction, the adhesion areas being respectively formed on both sides of the cutting position in the transport direction, and at least some of the plurality of elastic members that are stretched in the transport direction contract in the transport direction towards the adhesion area from positions at which the at least some of the plurality of elastic members are cut, the contraction being performed while the at least some of the plurality of elastic members shifting relative to the lower exterior member and the upper exterior member; a process in which a welded section on which the folded lower bandlike member and the folded upper bandlike member are to be welded to each other is formed on each side of the cutting position in the transport direction; and a process in which the lower bandlike member and the upper bandlike member are cut together on the cutting position, and the lower exterior member and the upper exterior member which are shaped in the form of underpants are cut and separated from the lower bandlike member and the upper bandlike member. |
