This manufacturing device (10) for an absorbent body (3) comprises: a rotary drum (2) that has an accumulation recess (22) on the outer circumferential surface (21) thereof; and a duct (4) that supplies a molding material in a scattered state. The following are arranged in the interior of the duct (4): a scuffing roll (42) that scrapes off molding material that has accumulated within a space (4S) that is partitioned by a suspended plate (43); and a duct opening (44) that takes in external air on the downstream side. The interior of the duct (4) is divided by the suspended plate (43) into an accumulation area (PT) in which molding material in a scattered state is made to accumulate in an excessive manner so as to overflow from the accumulation recess (22) upstream from the suspended plate (43) and a re-accumulation area (RPT) in which accumulated excess molding material is scraped off by the scuffing roll (42) and made to accumulate again downstream from the suspended plate (43).本發明之吸收體(3)之製造裝置(10)具有:旋轉筒(2),其於外周面(21)具有集聚用凹部(22);以及管道(4),其將成形體材料以飛散狀態供給。於管道(4)之內部,於由垂下板(43)分隔之空間(4S)內,配置有刮取經纖維堆積之成形體材料之刮輥(42)、及於下游側吸入外部大氣之管道開口部(44)。管道(4)之內部被垂下板(43)分斷為纖維堆積區域PT及纖維再堆積區域RPT,上述纖維堆積區域PT係於較垂下板(43)更靠上游側,將飛散狀態之成形體材料以自集聚用凹部(22)溢出之方式過剩地纖維堆積,上述纖維再堆積區域RPT係於較垂下板(43)更靠下游側,利用刮輥(42)刮取經纖維堆積之過剩量之成形體材料並進行纖維再堆積。
