PROBLEM TO BE SOLVED: To reduce probability of cutting a rubber thread by mistake during processing to a composite sheet.SOLUTION: There is provided a production method of a composite sheet related to an absorbent article, for producing the composite sheet comprising a first continuous sheet, a second continuous sheet, and a rubber thread disposed between the first continuous sheet and the second continuous sheet. The production method is configured to rotate a first rotor comprising a first protrusion part and a second protrusion part protruding to outside of a radial direction and capable of rotating, then transport the first continuous sheet, the second continuous sheet and the rubber thread in a state of arranging at least a part of the rubber thread which is disposed between the first continuous sheet and the second continuous sheet, to a space between the first protrusion part and the second protrusion part, then sandwich the first continuous sheet and the second continuous sheet between the first protrusion part, the second protrusion part and a rotatable second rotor during transport by the first rotor, for performing processing to the first continuous sheet and the second continuous sheet.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】複合シートへの加工時に、誤って糸ゴムを切断する恐れを軽減させる。【解決手段】第1連続シート、第2連続シート、及び第1連続シートと第2連続シートの間に配置された糸ゴムとを有する複合シートを製造する吸収性物品に係る複合シートの製造方法であって、径方向外側に突出した第1突部及び第2突部を備えた回転可能な第1回転体を回転させて、第1突部と第2突部の間に、第1連続シートと第2連続シートの間に配置された糸ゴムの少なくとも一部を入れた状態で、第1連続シート、第2連続シート、及び糸ゴムを搬送し、第1回転体による搬送中に、第1突部及び第2突部と、回転可能な第2回転体との間で、第1連続シート及び第2連続シートを挟むことによって、第1連続シート及び第2連続シートに加工を施すことを特徴とする吸収性物品に係る複合シートの製造方法である。【選択図】図3
