PROBLEM TO BE SOLVED: To provide a fiber-stacking device capable of adjusting a fiber-stacking amount of a molding material without generating fiber-stacking irregularity.SOLUTION: A fiber-stacking device has, on an outer surface, a concave portion 22 for accumulation in which a molding material is laminated and, while conveying the concave portion 22 in one direction, laminates the molding material that is conveyed by an airflow generated by suction from the inner side on a bottom surface 22a of the concave portion 22 formed with a porous member 27 that has a plurality of suction holes. Adjustors 10 are disposed on the inner surface 27b side of the porous member 27. The adjustors 10 have a plurality of openings, and the openings have a smaller opening area at an opening end portion which is relatively farther from the porous member 27 compared with an opening end portion relatively nearer the porous member 27.COPYRIGHT: (C)2014,JPO&INPIT【課題】積繊ムラを発生させずに、成形体材料の積繊量を調整可能な積繊装置を提供すること。【解決手段】成形体材料が積繊される集積用凹部22を外面に有し、集積用凹部22を一方向に搬送しつつ、内部側からの吸引によって生じた空気流に乗って搬送された成形体材料を、吸引孔を複数有する多孔性部材27で形成された集積用凹部22の底面22a上に積繊させる。多孔性部材27の内面27b側に調整体10が配されている。調整体10は、複数の開口部を有し、該開口部は、多孔性部材27から相対的に遠い方の開口端部が相対的に近い方の開口端部に比して開口面積が小さい。【選択図】図4
