PROBLEM TO BE SOLVED: To provide a method for manufacturing an absorbent article sheet, which makes it easy to maintain manufacturing facilities.SOLUTION: The method for manufacturing an absorbent article sheet comprises a molding step in which a surface sheet 11 made of a liquid permeable material is sandwiched between a first recessed and projecting roll 25a with concavoconvex portions formed in its surface and a second concavoconvex roll 25b with concavoconvex portions formed in its surface, thereby molding the surface sheet 11 in a wavy form such that both its surface and back have a groove and a projection alternating in a flowing direction, a joining step in which, while the shape of the wavy molded surface sheet 11 is maintained, the tops of the projections of the back of the wavy molded surface sheet 11 and the surface of a back sheet 17 made of a liquid permeable material are joined to obtain a long joined body 19, and an absorbent article sheet forming step in which the long joined body 19 thus obtained is cut into a predetermined length, thereby obtaining a plurality of absorbent article sheets 21.COPYRIGHT: (C)2012,JPO&INPIT【課題】製造設備の維持管理が容易な吸収性物品用シートの製造方法を提供する。【解決手段】液透過性材料からなる表面シート材11を、その表面に凹部及び凸部が形成された第1凹凸ロール25aと、その表面に凹部及び凸部が形成された第2凹凸ロール25bとの間に挟み込むことによって、前記表面シート材11を、その表面側及び裏面側の双方に、流れ方向に沿って複数の凹溝と複数の凸条とが交互に形成された波形に成形する成形工程と、波形に成形された前記表面シート材11の形状を維持した状態で、波形に成形された前記表面シート材11の前記複数の凸条のうちの裏面側に形成されたものの頂部と液透過性材料からなる裏面シート材17の表面とを接着させて長尺接着体19を得る接着工程と、得られた前記長尺接着体19を所定の長さで切断して複数の吸収性物品用シート21を得る吸収性物品用シート作製工程と、を備える吸収性物品用シートの製造方法。【選択図】図1
