PROBLEM TO BE SOLVED: To prevent damage in cover sheet forming a peripheral part of a cover upon compressing the cover with a plurality of projecting parts on a peripheral surface of a rotation member for a purpose of enhancing rigidity in the cover of an absorber.SOLUTION: A cover of a laminated product is formed by covering the laminated product in which liquid absorbing materials are laminated, with a liquid-permeable cover sheet. The cover is passed between peripheral surfaces of a pair of rotation members which rotate in a manner where the cover is transferred along with transporting direction of the formed cover. The cover is compressed with a plurality of projecting parts arranged on the peripheral surface of at least one rotation member among the pair of rotation members in the passing process. The plurality of projecting parts are arranged between projecting parts adjacent to each other in rotating direction of the rotation members and projecting parts adjacent to each other in CD direction orthogonal to the rotating direction with an interval respectively. The projecting parts each have a horizontally long shape with longitudinal direction. The longitudinal direction of the projecting parts is along with the CD direction.COPYRIGHT: (C)2015,JPO&INPIT【課題】吸収体に係る被覆体の剛性を高める目的で回転部材の外周面の複数の突部によって当該被覆体を圧搾する際に、被覆体の外周部をなす被覆シートの破損を防ぐ。【解決手段】液体吸収性素材が積層されてなる積層体を液透過性の被覆シートで被覆することにより、積層体の被覆体を生成することと、生成された被覆体の搬送方向に沿って被覆体を送り出すように回転する一対の回転部材の外周面同士の間に被覆体を通すことと、前記通すことにおいて、一対の回転部材のうちの少なくとも一方の回転部材の外周面に設けられた複数の突部によって被覆体を圧搾することと、を有する。複数の突部は、前記回転部材の回転方向に隣り合う突部及び回転方向と直交するCD方向に隣り合う突部との間にそれぞれ間隔をあけて設けられている。突部の形状は長手方向を有した横長形状である。突部の長手方向はCD方向に沿っている。【選択図】図7
