Method for manufacturing absorbent article and absorbent sanitary article

A method of producing an absorbent article comprising an absorber, a liquid pervious top sheet comprising a non-woven fabric covering a front side of the absorber, and a second sheet bonded to a back side of the top sheet, wherein a plurality of of extruded protrusions embossed from the back side to a front side of the top sheet is arrayed at intervals in a width direction and a front-back direction respectively, and a plurality of top-second bonded portions arrayed in an intermittent bonding pattern in the width direction and the front-back direction is provided through pressure welding of the top sheet and the second sheet at areas between the extruded protrusions adjacent each other in the width direction and the front-back direction, the method comprising:

• assembling the top sheet and the second sheet, the assembling comprising:
• transferring the non-woven fabric to be the top sheet by being drawn from downstream of a production line while forming the extruded protrusions in the non-woven fabric through embossing;
• after said transferring the non-woven fabric, aligning a material of the second sheet with a back side of the non-woven fabric having the extruded protrusions;
• and
• bonding the non-woven fabric and the material of the second sheet into a bonding pattern such that in regions between the extruded protrusions adjacent each other in a machine direction, rows of a plurality of top-second bonded portions disposed at intervals in a cross direction orthogonal to the machine direction are provided through center positions of the regions in the cross direction,
• wherein areas between the top-second bonded portions in the cross section comprise compressed portions in each of which the top sheet and the second sheet are unwelded and the top sheet is more highly compressed than areas at both sides of the compressed portions in the machine direction, the compressed portions being concave and being formed on the front side of the top sheet, and a back surface of the compressed portion contacting the second sheet and being devoid of a space between the back surface of the compressed portion and the second sheet.
