Abstract:
1. A method to produce an absorbent article in the form of diaper pants, comprising: obtaining a blank comprising an absorbent body enclosed between an inner, liquid-permeable cover sheet and an outer cover sheet, at least one cover sheet being made of a thermally-weldable material; a front portion; a rear portion; and a crotch portion extending between the front and rear portions, wherein the crotch portion includes and is delimited by leg openings of the blank; wherein the front portion and rear portion have side parts extending laterally outside the absorbent body from a waist band to the leg openings; folding in side-edge portions of the side parts of one or both of the rear portion or front portion towards the inner cover sheet over respective supports placed in the side parts of either the rear or front portion and extending along the full length of the side-portions; folding the blank about a transverse line in the crotch portion so that the end edges of the front portion and rear portion come to lie edge-to-edge and so that the side-edge portions of the front or rear portion overlap the folded-in side-edge portions of the other of the front or rear portion; welding together the overlapping side-edge portions of the side parts within the area of the supports by means of ultrasonic or thermal welding, wherein the side-edge portions are secured to the respective supports via a clamp part that secures the side-edge portions between a surface of the respective supports and a surface of the clamp part.
