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 5 |
