ABSTRACT:
A method for forming a disposable absorbent article having portions which are elastically extensible in at least the cross-machine direction. The method generally comprises the steps of providing a chassis comprising: a liquid pervious topsheet, a liquid impervious backsheet joined with said topsheet, and an absorbent core positioned between said topsheet and said backsheet; providing a first lamina, said first lamina being joined to said chassis and having pleats, said pleats being oriented in a second direction; providing at least one elastomeric lamina in face to face relation with at least a portion of said first lamina; providing two circumferentially grooved rolls, a first roll and a second roll, having mutually parallel axes and defining a nip therebetween, at least said first roll having a plurality of circumferential grooves and lands intermediate said grooves, said grooves being oriented in said second direction; passing said first lamina and said elastomeric lamina in face to face relation through said nip, such that said pleats of said first lamina face said grooves of said first roll; transversely registering the pleats of said first lamina with said grooves of said first roll; pressing said rolls together about the plane generally perpendicular to and connecting the axes of said rolls so that said first lamina contacts said elastomeric lamina at a position corresponding to said lands; and bonding said first lamina to said elastomeric lamina at said positions of contact.
