Publication number: 20030144643Abstract: An elasticized web has a gatherable substrate and a multi-strand elastic yarn affixed to the gatherable substrate at a plurality of fixation locations. So that the yarn can be affixed to the substrate without the use of an adhesive, the yarn is subjected to forces to create partial delamination of the yarn at the fixation locations and a portion of the gatherable substrate is caused to pass between the thus delaminated strands of the multi-strand elastic yarn. The elasticized web of the present invention is particularly suitable for use in disposable absorbent articles.Type: ApplicationFiled: December 26, 2002Publication date: July 31, 2003Inventors: Christian Jarpenberg, Michael Linder, Jose-Maria Mansisidor, Asa Lindstrom, Karin Lindmark, Ingemar Fernfors, Kenneth Strannemalm
