Document Type and Number:
WIPO Patent Application WO/2019/123781
Kind Code:
A1
Abstract:
Provided is a method for manufacturing an absorbent article which can stably maintain the shape of compressed parts and prevent an absorbent body from hardening. This method for manufacturing an absorbent article (1) comprises: a supply step of supplying at least an absorbent body (P3) into a gap between a pair of rolls which is provided with a first roll (30) having a plurality of first protrusions (32) on the outer circumferential surface thereof and a second roll (40) having a plurality of second protrusions (42) on the outer circumferential surface thereof; and a formation step of forming a plurality of compressed parts (12) by causing each of the plurality of first protrusions and each of the plurality of second protrusions to oppose one another while inserting at least the absorbent body between the first roll and the second roll and compressing the absorbent body from both sides in the thickness direction. The first roll and the second roll are configured so that in a state in which each of the first protrusions and each of the second protrusions forming the compressed parts oppose one another, the projection of a first area (A1) of a peak portion (32t) of each first protrusion on a second area (A2) of a peak portion (42t) of the corresponding second protrusion is located within the second area.
