PROBLEM TO BE SOLVED: To provide a fiber stacking device which is excellent in transfer performance of a fiber stack in a collecting/stacking recess of a rotary drum, and in particular, which can efficiently produce an absorbent body partly different in basis weight.SOLUTION: On the inner surface side of a porous member 27, a space part 26 defined by the porous member 27 and drum side walls 25 is formed. The space part 26 communicates with an outside through suction opening parts 29. On end parts in the rotation axis direction of a rotary drum 2, non-rotary suction chambers 8 are adjacently arranged so as to cover the suction opening parts 29. Along the circumferential direction of the rotary drum 2, the suction chambers 8 each include: a suction area 80 for allowing the suction opening parts 29 to communicate with suction means and a non-suction area 81 for blocking the suction opening parts 29. In an area corresponding to the suction area 80 within the rotary drum 2, a non-rotary suction suppression plate 9 for blocking a transfer opening part 224 is arranged along the circumferential direction of the rotary drum 2.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】回転ドラムの集積用凹部内の積繊物の転写性に優れ、特に坪量が部分的に異なる吸収体を効率良く製造することができる積繊装置を提供すること。【解決手段】多孔性部材27の内面側に、該多孔性部材27とドラム側壁25とで画成された空間部26が形成され、該空間部26は、吸引用開口部29を介して外部と連通している。回転ドラム2の回転軸方向端部に、不回転の吸引チャンバー8が吸引用開口部29を覆うように隣接して配されている。吸引チャンバー8は、吸引用開口部29と吸引手段とを連通する吸引領域80と、吸引用開口部29を閉塞する非吸引領域81とを、回転ドラム2の周方向に沿って有している。回転ドラム2の内部の吸引領域80に対応する領域に、転写用開口部224を閉塞する不回転の吸引抑制プレート9が回転ドラム2の周方向に沿って配されている。【選択図】図5
