Disposable absorbent article and method of manufacturing the same
A disposable absorbent article comprises an outer cover, and an absorbent member attached to the skin facing side of the outer cover. The absorbent member includes an absorber. At least a crotch zone of the outer cover is subjected to a softening process for softening a material of the outer cover.
1. A method of manufacturing a disposable absorbent article having a crotch zone extending an entirety of the absorbent article in a lateral direction from a first leg-side edge for surrounding a wearer's first leg and a second leg-side edge surrounding the wearer's second leg, the absorbent article having an outer cover and an absorbent member attached to a skin facing side of said outer cover, said absorbent member including an absorber, the absorbent article having elastic members attached from along the leg-side edges of said outer cover surrounding a wearer's left and right legs across the crotch zone, said method comprising the steps of:
softening a continuous material to become said crotch zone of said outer cover while transporting said continuous material in its longitudinal direction, said continuous material being a series of material for fanning said outer cover and extending continuously in a lateral direction of said absorbent article;
attaching said absorbent member to said continuous material;
cutting said continuous material, with said absorbent member attached thereto, into products; and
attaching said elastic members continuously to said continuous material while transporting said continuous material in said longitudinal direction; and
wherein said softening comprises applying blades of a cutter to said continuous material to become the crotch zone of said outer cover to thereby soften said continuous material, wherein parts of said elastic members positioned in said crotch zone are cut short so as to be weakened, and wherein all of the continuous material that is to become the crotch zone is passed between a blade roller serving as the cutter and an anvil roller so that a plurality of slit-like holes is formed in the continuous material laterally across an entirety of the crotch zone.
2. The method of manufacturing of claim 1 , wherein the blade roller creating the slit-like holes has a plurality of blades distributed along an entire circumference of the blade roller.
