Abstract
An absorbent member manufacturing method of the present invention is a method for manufacturing an absorbent member () for an absorbent article and including synthetic fibers () and hydrophilic fibers (). The method involves: a transporting step of transporting the hydrophilic fibers () and a plurality of sheet fragments () to an accumulating depression () by using a duct (); an accumulating step of accumulating, in the accumulating depression (), the plurality of sheet fragments () and the hydrophilic fibers (), and obtaining an accumulation () which is a constituent member of the absorbent member (); and a depression forming step of forming a depression () in the accumulation () by applying pressure to a portion thereof. In the transporting step, the sheet fragments () and the hydrophilic fibers () are brought into contact with one another in an airflow created inside the duct (), and the sheet fragments () and the hydrophilic fibers () are transported by the airflow in a dispersed and airborne state in which the sheet fragments and the hydrophilic fibers are mixed.
