PROBLEM TO BE SOLVED: To suppress a hard spot which can be generated when a laminate related to an absorbent article is compressed.SOLUTION: An apparatus manufactures an absorber by compressing a laminate formed by laminating a liquid absorbent material in a thickness direction of the laminate. The apparatus includes a pair of rotating members which rotates to send out the laminate, which is sent in along a conveyance direction, in the conveyance direction while tightly compressing the laminate by mutual peripheral surfaces and a plurality of linear protruding parts which protrude on the peripheral surface of at least one of the pair of the rotating members. The adjacent protruding parts in a CD direction along a rotating shaft of the rotating member out of the plurality of the linear protruding parts section into a region sandwiched with respect to the CD direction on the peripheral surface. The sectioned region has a taper shaped region part where a dimension in the CD direction is reduced toward an upstream side of the rotating direction of the rotating member. In a tip end part in the taper shaped region part, the adjacent protruding parts face each other via a gap between them.COPYRIGHT: (C)2015,JPO&INPIT【課題】吸収性物品に係る積層体を圧縮する際に生じ得るハードスポットを抑制する。【解決手段】液体吸収性素材が積層されてなる積層体を前記積層体の厚さ方向に圧縮して吸収体を製造する装置である。搬送方向に沿って送り込まれる前記積層体を、互いの外周面で挟圧しながら前記搬送方向に送り出すように回転する一対の回転部材と、前記一対の回転部材のうちの少なくとも一方の回転部材の前記外周面に突出して設けられた複数の線状の突部と、を有する。前記複数の線状の突部のうちで、前記回転部材の回転軸に沿うCD方向に隣り合う突部同士は、前記CD方向に関して挟まれた領域を前記外周面に区画する。区画された前記領域は、前記回転部材の回転方向の上流側に向かうに従って前記CD方向の大きさが小さくなった先細り形状の領域部分を有する。前記先細り形状の領域部分の先端部において、前記隣り合う突部同士は、互いの間に隙間を介して対向している。【選択図】図7
