Patent number: 7078089Abstract: Disclosed herein are elastic laminate materials. The elastic laminate materials are laminates of extensible nonwoven fibrous webs and thermoplastic elastic materials. The laminate may be a two-layer composite material having a single nonwoven fibrous web bonded to one side of the thermoplastic elastic material, or it may be a three-layer composite having a nonwoven fibrous web bonded to each side of the thermoplastic elastic material. The extensible nonwoven fibrous webs may be staple fiber webs. The thermoplastic elastic material may be single-layer or multi-layer elastic films, or elastic fibrous layers. Where single- or multi-layer elastic films are used, the films may be breathable films. The elastic material, or some of the staple fibers, or both, may be selected such that the staple fiber webs are thermally compatible with the thermoplastic elastic material to facilitate laminate bonding. Processes for forming the elastic laminate material are also disclosed.Type: GrantFiled: December 28, 2001Date of Patent: July 18, 2006Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Clifford Jackson Ellis, Arthur Edward Garavaglia, Jay Sheldon Shultz

Patent number: 7052761Abstract: A balanced dimensionally stable laminate uses a web carrier which is removably attached to a layer of the laminate during lamination and processing. The web carrier maintains dimensional stability of the layers of the laminate during lamination and processing and after removal of the web carrier. The web carrier is removed if at all only after the laminate is formed and processed. The bonding force of the web carrier with at least one of the polymers layer resists forces which would otherwise dimensionally distort the layers of the laminate or design features thereof during lamination, particularly in thermal roll-forming lamination. The layers of the laminate, which may include print and texture design features, remain dimensionally stable after removal of the web carrier. The web carrier can be removed at any time prior to or after final application of the laminate to a substrate.Type: GrantFiled: September 24, 2003Date of Patent: May 30, 2006Assignee: Schneller, Inc.Inventors: Robert Pierson, Dale Onderak, Mark Tennant, Ray Cull

Patent number: 7029546Abstract: The invention concerns a method for making a sheet of paper comprising at least two crimped cotton-wool-like cellulose plies (20, 40). It consists in: unwinding a first ply (20) in the form of a strip from a reel, embossing it on an embossing unit (10, 12) and forming protuberances at its surface, unwinding a second ply (40) in the form of a strip from a reel, guiding it downstream of the embossing unit (10, 12), superposing the two strips, with their protuberances facing inwards, and in applying a linking means (14, 16) so as to make the two strips integral with each other. Said method is characterised in that immediately upstream of said linking means (14, 16), a tension regulating means (18) is applied in the machine direction on one of the strips, such that the two strips have the same elastic deformation in the machine direction when the linking means is applied. The invention also concerns a product obtained by said method.Type: GrantFiled: September 27, 2001Date of Patent: April 18, 2006Assignee: Georgia-Pacific FranceInventors: Michel Basler, Pierre Laurent, Gilles Roussel, Rėmy Ruppel

Patent number: 7022272Abstract: Disclosed is a method of manufacturing a mechanically and chemically embossed surface covering having selectively textured surfaces. The method includes forming a web coated with a wear layer. The coated web is heated to a temperature at which the wear layer is cured, the foam layer expands, and the pattern is chemically embossed to form a surface covering having foamed regions and nonfoamed regions. The temperature gradient of the surface covering is adjusted such that there is a temperature gradient difference between the foamed and nonfoamed regions. A surface texture is then mechanically embossed into the wear layer and selectively set onto the wear layer substantially overlying the non-foamed regions.Type: GrantFiled: April 2, 2003Date of Patent: April 4, 2006Assignee: AWI Licensing CompanyInventors: W.

Patent number: 6986825Abstract: A method of and apparatus for laminating a first material (40) such as a spunbonded polymer having a point emboss pattern (41) formed thereon, to a second material (43) such as a polymer film, involves use of a lamination process using a point lamination pattern (56) provided on a heated calender roll (50). One or more geometric characteristics of two patterns (41, 56) such as bonding/contact area, pitch or angle of axes, is selected and differentiated, prior to lamination, to control, during lamination, the amount of point or mis-registration between the two patterns (41, 56). The laminate (60) can have optimum all over lamination if the amount of point mis-registration is maximized. An adhesive can be provided between the first and second materials (40, 43) to enable lamination of dissimilar composition materials.Type: GrantFiled: April 30, 1999Date of Patent: January 17, 2006Assignee: Hunt Technology LimitedInventors: Leslie James Squires, Timothy Woodbridge
