PROBLEM TO BE SOLVED: To provide a manufacturing device for an absorbent body enabling downsizing of the scale of facilities and reduction in cost for the device.SOLUTION: A manufacturing device 1 for an absorbent body 100 manufactures an absorbent body different in a compounding ratio of fibrous materials 10a, 10b in a thickness direction. The manufacturing device 1 includes: a supply part 2 which supplies at least two kinds of fibrous materials 10a, 10b in a width direction so as to be different in the compounding ratio a duct 3 which conveys the fibrous materials 10a, 10b supplied from the supply part 2 in a dispersed condition a rotary drum 4 which has an accumulation recessed part 41 for accumulating the fibrous materials 10a, 10b conveyed from the duct 3, on an outer peripheral surface 4f and folding means 5 which folds a fiber-accumulated body 100a formed by transferring the fibrous materials 10a, 10b accumulated on the accumulation recessed part 41 of the rotary drum 4, in the width direction. The duct 3 has a partition board 35 partitioning the inside thereof in the width direction.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】設備の規模をコンパクト化でき、製造装置のコストも抑えることができる吸収体の製造装置を提供すること。【解決手段】本発明の吸収体100の製造装置1は、厚み方向に繊維材料10a,10bの配合割合が異なる吸収体を製造する。製造装置1は、2種以上の繊維材料10a,10bを幅方向に配合割合が異なるように供給する供給部2と、供給部2から供給された繊維材料10a,10bを飛散状態にて搬送するダクト3と、ダクト3から搬送された繊維材料10a,10bを集積する集積用凹部41を外周面4fに有する回転ドラム4と、回転ドラム4の集積用凹部41に集積された繊維材料10a,10bを転写して形成される積繊体100aを幅方向に折り重ねる折り手段5とを備える。ダクト3は、その内部を幅方向に仕切る仕切板35を有している。【選択図】図1
