Abstract: A method of applying curved leg elastics to absorbent garments involves stretching and wrapping a pair of elastic ribbons about a first curved surface of a pair of pucks. A portion of each of the elastic ribbons is simultaneously folded onto a second surface of each of the pucks. The pucks are attached to a rotating device that rotates the pucks into alignment with a substrate. As the pucks are rotated toward the substrate, the pucks are also oscillated individually toward the substrate. Once the second surfaces of the pucks are aligned parallel to the substrate, the substrate is bonded to the second surface portion of each of the elastic ribbons in their stretched positions on the pucks, thereby forming finished seams. The resulting absorbent garments have gasket-like leg openings with improved comfort and aesthetic appeal.

Abstract: A method of securing an elastic band between two material layers which are at least partially defined by meltable material includes forming perforations in the elastic band, placing the elastic band between two material layers, and bonding the material layers to one another through the perforations by heat fusion, wherein the perforations in the elastic band are formed at the same time as the material layers are fused together (i.e., the formation of the perforations in the elastic band is directly followed by bonding together, through the perforations, portions of the material layers). An elastic band secured between two material layers for inclusion in articles of one-time use includes the use of material layers that are at least partially defined by meltable material and an elastic band having perforations formed therein. The material layers are positioned on opposite sides of the elastic band and are joined together by heat fusion.
