A device for manufacturing an absorber in an absorbent article by passing a gas comprising a liquid absorbent material through an air permeable member in a thickness direction, and laminating the liquid absorbent material onto the air permeable member. The air permeable member is constituted such that a plurality of plates is stacked in the thickness direction. Each of the plurality of plates has a plurality of air holes that penetrate in the thickness direction and pass the gas through. The plurality of air holes in each plate is arranged so as to connect with the corresponding air hole in the adjoining plate in the thickness direction. With respect to all the plates stacked in the thickness direction, the air holes that correspond to each other are formed in the same shape, and junctions that join adjoining plates in the thickness direction are formed in places where air holes are not formed in the plates.本發明之課題在於解決會在為了提高通氣性構件之積層效率時發生的通氣性構件之耐久性降低的問題、以及液體吸收性素材積層時之通氣性構件堵塞的問題。本發明之解決手段是使包含液體吸收性素材的氣體通過通氣性構件的厚度方向,藉此將前述液體吸收性素材積層在前述通氣性構件而製造吸收性物品之吸收體的裝置。前述通氣性構件是在前述厚度方向堆積複數個片材而構成。前述複數個各片材具有朝前述厚度方向貫穿而可供前述氣體通過的複數個通氣孔。前述各片材的前述複數個通氣孔是被配置成與在前述厚度方向相鄰的片材之對應的通氣孔連通。關於在前述厚度方向堆積的所有片材,相互對應的前述通氣孔彼此是形成相同的形狀,並且在前述各片材當中未形成前述通氣孔的部分,形成有將在前述厚度方向相鄰的片材接合的接合部。27...成形模板材27a...開口部50...通氣性構件50h...通氣孔55...片材55b...通氣孔非形成部分55G...通氣孔列55h...通氣孔55j...接合部56h...基準孔
