and the first continuous sheet which is continuous to the transport direction, and the second continuous sheet which is continuous in the conveying direction During, and convey the elastic members in the regions where the composite sheet comprising it is fixed in a region corresponding to at least the high elastic region while the elastic member which is continuous in the conveying direction in the conveying direction in a stretched state is inserted, corresponding to a low-stretch region is cut in the direction of one place, the resilient member, by shrinking towards the area corresponding to the high stretching region, and be formed by arranging a high stretch region and the low-stretch region in the composite sheet in the conveying direction, the It has. In that the formed can, between the cutter rotor and the anvil rotating member that rotates to face the outer peripheral surface of each other, when the composite sheet passes along the conveyance direction, the cutter blade of the outer circumferential surface of the cutter rotary body The formation and the anvil rotating body, by nipping the composite sheet in a state where a gap between each other, the clamping pressure position in the composite sheet, the crimp portion of the first continuous sheet and the second continuous sheet and while, to cut the elastic member.搬送方向に連続する第1連続シートと、搬送方向に連続する第2連続シートとの間に、搬送方向に伸長状態で搬送方向に連続する弾性部材が介挿されつつ少なくとも高伸縮領域に対応する領域において固定されてなる複合シートを、低伸縮領域に対応する領域において弾性部材を搬送方向の一カ所で切断して、弾性部材を、高伸縮領域に対応する領域の方へ収縮させることにより、複合シートに高伸縮領域と低伸縮領域とを搬送方向に並べて形成することと、を有する。形成することにおいては、互いの外周面を対向して回転するカッター回転体とアンビル回転体との間を、複合シートが搬送方向に沿って通過する際に、カッター回転体の外周面のカッター刃とアンビル回転体とが、互いの間に隙間を有した状態で複合シートを挟圧することにより、複合シートにおける挟圧された位置に、第1連続シートと第2連続シートとの圧着部を形成しつつ、弾性部材を切断する。
