Publication number: 20140073211Abstract: Systems and methods for forming an elastic laminate may be disclosed. For example, an elastic material may be extruded onto a first nonwoven web. In the extrusion, the elastic material may be directly applied to the first nonwoven web continuously in a machine direction and discontinuously in a cross direction to form the elastic laminate with one or more elastic strips on the first nonwoven web. The elastic material may also be applied unevenly or non-uniformly in the cross direction strips on the first nonwoven web. A second nonwoven web may be bonded to the first nonwoven web with the one or more elastic strips. The first or second nonwoven may also be pre-activated to further improve stretch and/or softness.Type: ApplicationFiled: September 10, 2013Publication date: March 13, 2014Inventor: Stephen D. Bruce

Patent number: 7625829Abstract: An elastomeric film is bonded between two or more layers of nonwoven webs formed of nonelastomeric thermoplastic fibers. The laminate has, in a predefined transverse direction, an elastic elongation value greater than the predefined elastic elongation value of the nonwoven webs, and an ultimate force to break in the predefined transverse direction of at least 3000 g/in. The laminate advantageously provides a tear resistant, multiple ply, fabric that is soft to the touch as a result of the outwardly disposed nonwoven webs, and has a high elastic modulus. The laminate is particularly useful in applications where closure portions of a product must be stretched to keep the product in place when worn.Type: GrantFiled: January 27, 2000Date of Patent: December 1, 2009Assignee: Tredegar Film Products CorporationInventors: James W. Cree, Jeffrey A. Middlesworth, Stephen D. Bruce

Patent number: 7507680Abstract: A method for manufacturing composite webs and composite webs made thereby in which the web includes a perforated thermoplastic film and one or more nonwoven webs. The method provides a perforated thermoplastic film, a creped nonwoven web, the webs are fed in a face to face relationship to be bonded. The perforated thermoplastic film and the creped nonwoven web are bonded in a face to face relationship at a plurality of points of contact such that the creped structure of the nonwoven web is maintained and the composite web has a nonwoven face and a film face. The composite webs are extensible at least in the direction of the creping.Type: GrantFiled: November 12, 2003Date of Patent: March 24, 2009Assignee: Tredegar Film Products CorporationInventors: Jeffrey Alan Middlesworth, Tze Wan Pansy Chung, Stephen D. Bruce, James D. Tribble

Patent number: 7351297Abstract: A method for producing a composite web includes supplying two or more webs to an activation mechanism, where the webs are in an unbonded state relative to each other. The method further entails simultaneously activating the webs while they are in a face to face relationship and in an unbonded state, and then bonding the webs to form a composite web.Type: GrantFiled: September 21, 2004Date of Patent: April 1, 2008Assignee: Tredegar Film Products Corp.Inventors: Jeffrey Alan Middlesworth, Tze Wan Pansy Chung, Stephen D.

Patent number: 6720279Abstract: A three-dimensional highly elastic film/non-woven composite having a fluid and air impervious core layer and a first and second consolidated layer. The consolidated layers have unidirectional and non-unidirectional fibers. The composite is formed by laminating the air and fluid impermeable elastic core layer between the two layers of consolidated non-wovens. The resulting composite stretches only in the cross-machine direction due to the unidirectional properties of the consolidated non-woven material. The layers are then point bonded or welded together. Preferably the layers are welded by passing the composite between an ultrasonic horn and an ultrasonic bond roll having raised areas for effecting the weld points. A thin inelastic membrane is formed at each of the weld points. The welded composite may then be pre-stretched to rupture the membranes, thereby creating apertures, which makes the composite permeable.Type: GrantFiled: December 17, 2002Date of Patent: April 13, 2004Assignee: Tredegar Film Products CorporationInventors: James W. Cree, Jeffrey A. Middlesworth, Stephen D. Bruce
