PROBLEM TO BE SOLVED: To provide a manufacturing method for precisely and stably arranging tape-like sheet materials at predetermined intervals.SOLUTION: The method for manufacturing an underpants-type wearing article is as follows. A plurality of tape-like sheet materials 33T are formed by slitting a first sheet material 1S in the width direction. They are conveyed in alternately different directions from each other to be divided for the belly side and the back side while keeping their positions in the width direction when they were slit. Each of the tape-like sheet materials 33T for the belly side and the back side are layered and fixed on a second sheet material 2S while keeping their positions in the width direction when they were slit, thereby obtaining a continuous members 11S for an outer body arranged on the belly- and back-side parts 21 and 23. Then, the continuous members 11S for the outer body arranged on the belly- and back-side parts 21 and 23 are adjusted their positions at the predetermined intervals D. An absorptive body 40 is layered across the second sheet materials 2S of the respective continuous members 11S for the outer body, while these second sheet materials 2S are faced inward so as to mutually overlap the respective continuous members 11S for the outer body and bond them widthwise together at the predetermined intervals. The continuous members 11S for the outer body are cut off widthwise at the joint.COPYRIGHT: (C)2013,JPO&INPIT【課題】テープ状シート材を所定間隔に精度よく安定的に配する製造方法を提供する。【解決手段】第1シート材1Sを幅方向に複数にスリットして複数本のテープ状シート材33Tを形成し、それらをスリット時の幅方向位置を維持して交互に異なる方向に搬送させて腹側用と背側用に分離し、腹側用と背側用の各テープ状シート材33Tを、スリット時の幅方向位置を維持して腹側と背側の別々の第2シート材2Sに積層して固定し、腹側部21と背側部23に配される外装体連続部材11Sを得た後、腹側部21と背側部23に配される外装体連続部材11Sを所定間隔Dに位置調整し、各外装体連続部材11Sの第2シート材2S上の間を渡すように吸収性本体40を積層し、第2シート材2S同士を内側に対向させて各外装体連続部材11S同士を重ね合わせて幅方向に所定間隔で接合し、その接合部で外装体連続部材11Sを幅方向に切断するパンツ型着用物品の製造方法を提供する。【選択図】図7
