PROBLEM TO BE SOLVED: To easily and securely change a shape of an absorbent article which is an extended-sheet state before finish, into an underpants type state.SOLUTION: There is provided a production method of an absorbent article. The production method of the absorbent article comprises: forming an absorbent article which is a state before finish, and which comprises: an absorbent body for absorbing a liquid a pair of belt members laminated to the absorbent body, and arranged in a width direction crossing a longitudinal direction of the absorbent body, and fixed to respective end part of the longitudinal direction on the absorbent body and leg-surrounding opening parts formed on both sides of the width direction folding into half, the absorbent article at a predetermined position in the longitudinal direction, by a folding-into half device, so that a skin side face of the absorbent body is inside while performing folding into half, moving the pair of belt members to outside of the width direction by a protrusion device, for protruding the belt members to outside of the width direction relative to the absorbent body.SELECTED DRAWING: Figure 14COPYRIGHT: (C)2017,JPO&INPIT【課題】延板状態たる完成前の状態の吸収性物品を、パンツ型状態へと容易且つ確実に形態変更可能にする。【解決手段】吸収性物品の製造方法である。液体を吸収する吸収性本体と、前記吸収性本体に重ね合わせられつつ、前記吸収性本体の長手方向と交差する幅方向に並んで配された一対のベルト部材であって、前記吸収性本体における前記長手方向の各端部に固定された前記一対のベルト部材と、前記幅方向の両側にそれぞれ形成された脚回り開口部と、を有した完成前の状態の吸収性物品を生成することと、前記吸収性本体の肌側面が内側となるように、二つ折り装置が前記吸収性本体を前記長手方向の所定位置で二つ折りすることと、前記二つ折りすることを行いながら、突出装置が前記一対のベルト部材を前記幅方向の外側に移動することによって、前記吸収性本体よりも前記幅方向の外側に前記ベルト部材を突出させることと、を有する。【選択図】図14
