PROBLEM TO BE SOLVED: To attach a planar elastic flexible member in a state extending along the width direction of the disposable diaper to a prescribed part around the waist of a disposable diaper without using a turnover device.SOLUTION: A manufacturing method of a disposable diaper includes: a first transportation process for transporting a long-sized elastic material 120 which is an original member of an elastic flexible member 20 in a lengthwise direction as a transportation direction M a widening process for expanding the elastic material 120 in a lateral direction C orthogonal to the transportation direction M in the first transportation process a cutting process for cutting the expanded elastic material 120 in the lateral direction C to make isolated elastic flexible members 20 after the widening process and a transfer process for attaching the elastic flexible member 20 made in the cutting process to a prescribed part in the disposable diaper.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】反転装置を利用することなく,使い捨ておむつのウエスト周りの所定箇所に,面状の弾性伸縮部材を使い捨ておむつの幅方向に沿って伸長させた状態で取り付ける。【解決手段】使い捨ておむつの製造方法であって,弾性伸縮部材20の原部材である長尺の弾性資材120を、その長さ方向を搬送方向Mとして搬送する第1搬送工程と,第1搬送工程中に弾性資材120を、搬送方向Mと直交する横方向Cに引き伸ばす拡幅工程と,拡幅工程後に引き伸ばされた状態の弾性資材120を、横方向Cに切断して個別の弾性伸縮部材20を得る切断工程と,切断工程において得られた弾性伸縮部材20を、使い捨ておむつの所定箇所に取り付ける転写工程と,を含む。【選択図】図2
