Abstract:
1. A method of manufacturing an absorbent article having elastic members, said method comprising: feeding the elastic members in a machine direction by a guide unit including conveying a web that defines components of at least a part of the absorbent article in the machine direction; and moving each of the first and second feeding portions by the respective first and second motors alternately in a first direction and a second direction so that the elastic members are brought into contact with the web and are arranged in first and second predetermined waveforms on the web, wherein the first direction is directed from a center portion of the web to a first end portion thereof in a cross direction crossing the machine direction, and the second direction is directed from the first end portion of the web to a second end portion thereof that is opposite to the first end portion in the cross direction, and wherein in a planar view of the web and during said moving each of the first and second feeding portions, wherein the first and second predetermined waveforms defined by the first and second arm members respectively are different from each other, a length of the first arm member is different from that of the second arm member, and a dimension between the base of the first arm member and the nip point corresponding to the first arm member is unequal to that between the base of the second arm member and the nip point corresponding to the second arm member in the machine direction.
