Patent number: 8951239Abstract: A disposable diaper has an absorbent body, an outer covering sheet and two end holding sheets, and both end portions of the absorbent body are fixed between the end holding sheets and the outer covering sheet. Since a turndown portion of an upper end portion of the end holding sheet is bonded on an upper end portion of a first covering sheet, a waist covering portion has structure where the first covering sheet is laminated on the two-layered end holding sheet. Therefore, a thickness of the outer covering sheet can be reduced, while maintaining strength of the waist covering portion by appropriately selecting material of the end holding sheet, thereby to easily improve softness of the disposable diaper. Since an upper end of a second covering sheet is positioned below the turndown portion, softness and breathability in an area between the turndown portion and the second covering sheet is increased.Type: GrantFiled: July 11, 2011Date of Patent: February 10, 2015Assignee: Livedo CorporationInventors: Kenji Nakaoka, Yuki Takahashi

Patent number: 7834236Abstract: A multi-layered web is provided that includes an elastic web bonded to an inelastic web. The inelastic web has extensible and inextensible regions arranged along the machine direction. In the extensible regions, the inelastic web is bonded to the elastic web in a creped structure that is extensible by virtue of the creping. A continuous process is provided to manufacture a multi-layer web having extensible regions that are conjoined with regions that are inextensible by varying the tension that is applied during manufacture of the multi-layer web. The apparatus comprises an elastic web that is fed into a bonding nip, into which one or more inelastic webs are also provided. The elastic web is fed into the bonding nip under a tension that is alternated between a low value that is sufficient to ensure processing stability, and a higher value that provides an elongation to the elastic web.Type: GrantFiled: April 25, 2007Date of Patent: November 16, 2010Assignee: Tredegar Film Products Corp.Inventors: Jeffrey Alan Middlesworth, Stephen Donald Bruce, Todd Richard Skochodopole, Matthew John O'Sickey, Andrew James Peacock
