发明名称 Production method of absorbent body
摘要 A production method of an absorbent body is provided. The method includes the steps of: supplying a first cover sheet on an outer surface of a rotating pattern drum, said pattern drum being provided with a concavity formed in a predetermined shape on the outer surface thereof; adapting the first cover sheet to the shape of the concavity and supplying an absorbent material into the concavity to form an absorbent material layer adapted to the shape of the concavity on the first cover sheet; supplying a second cover sheet toward the outer surface of the pattern drum; and separating the first cover sheet together with the absorbent material layer from the outer surface of the pattern drum and superposing the first cover sheet together with the absorbent material layer on the second cover sheet to produce an absorbent body comprised of the first cover sheet, the second cover sheet and the absorbent material layer interposed between the first cover sheet and the second cover sheet. An absorbent body produced by this method has improved absorption properties and can be used for disposable diapers, pet sheets, sanitary napkins, and the like.
