Abstract: An absorbent article is provided to prevent pulp fibers and a superabsorbent polymer that constitute an absorbent body from leaking from openings, even if a top sheet does not cover the side wall portions of the absorbent body at the openings. The absorbent article includes: a liquid-permeable top sheet having openings; a back sheet; and an absorbent body having openings. At the openings of the top sheet and the openings of the absorbent body, the top sheet is detached from the absorbent body. The opening diameters of the openings on the clothing side of the top sheet are smaller than the opening diameters of the openings on the skin side of the absorbent body. An opening diameter of the openings on the clothing side of the absorbent body is no greater than the opening diameter of the openings on the clothing side of the top sheet.

Abstract: A cutter apparatus for cutting a workpiece of an absorbent article that is being transported in a transport direction, includes: a cutter roller having a cutter blade projecting from an outer circumferential surface thereof; and an anvil roller that receives the cutter blade at an outer circumferential surface thereof disposed to face the outer circumferential surface of the cutter roller. While rotating mutually in the transport direction, the cutter roller and the anvil roller cut the workpiece by allowing the workpiece to pass between the rollers. In at least one of the cutter roller and the anvil roller, a dynamic-balance correction section is provided which corrects the dynamic balance of the roller so that the sum of the values of balance quality (mm/sec) defined in JIS B 0905 at one end and the other end of the roller in a rotational-axis direction is 6 or less.

Abstract: Provided is an absorbent article that can prevent pulp fibers and a superabsorbent polymer (SAP) that constitute an absorbent body from leaking from openings, evening if a top sheet does not cover the side wall portions of the absorbent body at the openings. An absorbent article (1) comprises: a liquid-permeable top sheet (2) having openings (10); a back sheet (3); and an absorbent body (4) having openings (10). At the openings (10) of the top sheet (2) and the openings (10) of the absorbent body (4), the top sheet (2) is detached from the absorbent body (4), and the opening diameter (R2) of the openings (10) in the surface of the top sheet (2) on the clothing side is smaller than the opening diameter (R3) of the openings (10) in the surface of the absorbent article (4) on the skin side.
