Claim Text:
1. A fiber stacking device for forming a shaped product, the device comprising: a rotating drum that has, in an outer peripheral surface thereof, a collecting/stacking recess for forming the shaped product by stacking a shaped-product material by sucking the material with a bottom surface of the collecting/stacking recess, wherein the rotating drum comprises: a drum body; an inner shaping member; an outer shaping member; and an air-permeable porous member that forms the bottom surface of the collecting/stacking recess, each of the inner and outer shaping members has an opening defining section that partitions and forms a plurality of openings, the inner shaping member is disposed on an outer peripheral surface of the drum body, the air-permeable porous member is disposed on the inner shaping member, the outer shaping member is disposed on the air-permeable porous member, so that i) the air-permeable porous member is sandwiched between the outer shaping member and the inner shaping member ii) the inner and outer shaping members are arranged so as to overlap with the air-permeable porous member, iii) the openings of the inner and outer shaping members overlap with each other via the air-permeable porous member so that the opening defining section of the outer shaping member and the air-permeable porous member define together the collecting/stacking recess in a planar view thereof, an air permeability of the opening defining section of each said shaping member is lower than an air permeability of the air-permeable porous member, the plurality of the openings of the outer shaping member respectively overlap with the plurality of the openings of the inner shaping member, so that in a planar view of the collecting/stacking recess, the opening of the outer shaping member and the opening disposed in the inner shaping member which overlaps with the opening of the outer shaping member have substantially the same shape in terms of planar-view shape.
