Method for manufacturing an absorbent article

A method for manufacturing an absorbent article, the absorbent article comprising a top-surface sheet, a back-surface sheet, and an absorber interposed between the top-surface sheet and the back-surface sheet,

• wherein the top-surface sheet includes a non-heat fusible layer arranged on a skin side and made of a nonwoven fabric made of 100% by weight of cotton fiber and a heat-fusible layer arranged on a non-skin side and made of a heat-fusible fiber,
• a second sheet made of a heat-fusible fiber is arranged on the non-skin side of the top-surface sheet,
• the top-surface sheet is formed to have a flat skin-side surface, and a large number of compressed parts are formed on a non-skin side surface of the second sheet by integrally recessing the second sheet and the top-surface sheet toward the skin side by compression from the non-skin side of the second sheet,
• the method comprising:
• allowing the top-surface sheet to pass between a flat roll and a convex roll, the flat roll having a flat surface and not being heated, and the convex roll having a surface formed with a large number of protrusions and being heated at least at a time of compression to form a large number of intermediate compressed parts in a non-skin side surface of the top-surface sheet by integrally recessing the heat-fusible layer and the non-heat fusible layer toward a skin side, and
• then in a state in which the second sheet is laminated on the non-skin side of the top-surface sheet, allowing the top-surface sheet to pass between a second flat roll and a second convex roll, the second flat roll having a flat surface and not being heated, and the second convex roll having a surface formed with a large number of protrusions corresponding to the compressed parts and being heated at least at compression time, thereby heat-fusing and joining the second sheet and the heat-fusible fiber of the heat-fusible layer while forming the compressed parts.
