Patent number: 6734125Abstract: A woven textile fabric is disclosed which is formed of synthetic yarns of at least two different deniers to which a solid polymeric film is laminated. An adhesive polymeric coating is provided for adhering the solid polymeric film to the woven textile fabric. The combination of yarns of different deniers provides a superior adhesion surface for the polymeric film. The yarns and the polymeric coating are preselected respectively in deniers and thicknesses so as to render the fabric substantially impermeable to fluid under pressure, while maintaining superb packageability and anti-blocking properties for use in vehicle occupant restraint systems. An air bag incorporating the woven textile fabric of the invention and having two outer surfaces and pre-configured air holding cavities woven therein to which a solid polymeric film is bonded for receiving and containing fluid under pressure for use in a vehicle air restraint system is also disclosed.Type: GrantFiled: August 30, 2002Date of Patent: May 11, 2004Assignee: Bradford Industries, Inc.Inventor: Manuel J. Veiga

Patent number: 6530398Abstract: A multi-layer paper machine wire includes an upper fabric layer, a lower fabric layer and an additional layer disposed between the upper and lower fabric layers. The additional layer includes weft threads that alternate with binding threads. Warp threads of the upper fabric layer run over the weft threads of the additional layer and are interwoven with binding threads of the additional layer. Likewise, weft threads of the lower fabric layer run below the weft threads of the additional layer and are interwoven with binding threads of the additional layer.Type: GrantFiled: December 22, 1999Date of Patent: March 11, 2003Assignee: Voith Fabrics Heidenheim GmbH & Co. KGInventor: Arved H. Westerkamp

Patent number: 5217048Abstract: A 3-dimensional woven fabric which includes a plurality of stacked single-ply webs (A.sub.1, A.sub.2, A.sub.3, A.sub.4) each comprising a weft yarn (2) which cross-bridges between warp yarns (1) arranged in rows in each web. The adjacent webs are connected together by a second warp yarn (3) which cross-links to one of the warp yarns (1) at a cross-linking location or to the weft yarn adjacent the cross-linking location. The successive cross-linking locations are spaced in the weaving direction by at least one weft yarn course. A weaving method and a leno heald for use in producing such a fabric are described also.Type: GrantFiled: November 27, 1991Date of Patent: June 8, 1993Assignee: Tominaga Machine Mfg., Co., Ltd.Inventors: Yuushiro Takano, Tsutomu Kikuchi, Makoto Tanaka

Patent number: 4784190Abstract: A method for making a woven dryer fabric having different permeabilities in different sections across its width to control the moisture profile of a web being conveyed through the dryer section of the papermaking machine is disclosed. Additional cross machine yarns are interwoven only over a selected distance or distances across the fabric in the cross machine direction. The non-interwoven segments of the additional cross machine direction yarns form surface floats which are subsequently removed by shearing.Type: GrantFiled: April 9, 1984Date of Patent: November 15, 1988Assignee: Huyck CorporationInventor: Peter Mullaney

Patent number: 4469142Abstract: A papermakers fabric having surface floats on both the paper surface and the non-paper contacting surface for improved sheet contact area and improved abrasion resistance. The fabric also includes a plurality of stuffer pick receiving sheds defined by warp yarns used to weave the fabric. Each of these sheds may receive a stuffer pick, the construction of which will be determined by the permeability required in the finished fabric, while the warp and weft yarns used to define the fabric remain unchanged. The warp ends of the fabric terminate in a pin seam made up of a number of enlarged seam loops which are created when a select number of warp yarns are symmetrically rewoven into the fabric.Type: GrantFiled: September 30, 1980Date of Patent: September 4, 1984Assignee: Scapa Inc.Inventor: William J. Harwood
