Publication number: 20080311811Abstract: A press pad is provided for use in a laminate press. The pad includes a woven fabric of heat resistant strands wherein at least either the warp or the weft has a core made up of a plurality of strands within a sheath of an elastomeric material, and the other is made up of metal strands. Within the scale of the press pad, the strands making up the core lie substantially parallel to one another and to the longitudinal axis of the core. In use, therefore, when pressurized in the laminate press, the core structure collapses as the strands making up the core move relative to one another and the core tends to flatten out. This increases the springiness and compensation ability of the press pad without any loss of heat transfer ability.Type: ApplicationFiled: May 1, 2007Publication date: December 18, 2008Applicant: MARATHON BELTING LIMITEDInventor: Melvyn Douglas

Patent number: 5861348Abstract: The present invention provides a body-adhesive tape having adhesive properties preventing the tape from peeling off due to sweat when it is applied in an overlapped manner, and which also has good moisture permeability. In the body-adhesive tape, a base cloth is formed from a stretchable warp thread and a standard weft thread. On one side of the base cloth a plurality of pressure-sensitive adhesive layers are formed separated by appropriate gaps. The pressure-sensitive adhesive layers are formed so that they meander left and right along the length of the tape. At the gaps, the base cloth is exposed so there is permeability. Since the gap meanders, it is longer than the tape, and thus there is more exposure of the weave and more permeability. The pressure-sensitive adhesive layers meander so that the tape can be attached anywhere on the body and can respond to tension due to body movement from any direction.Type: GrantFiled: September 19, 1996Date of Patent: January 19, 1999Assignee: Kinesio Co., Ltd.Inventor: Kenzo Kase

Patent number: 5789065Abstract: Transversely stretchable elastic laminated fabric with cloth-like facings was made by a two-step process. In the first step an inelastic laminate was made by continuously extruding an elastomer sheet between two plies of a fibrous sheet and joining the plies by applying pressure on them between a closed gap niproll assembly. Two longitudinal slits were made into the laminate. Then the rolls of inelastic laminate so made were taken to an oven and the laminate was unwound and pulled through the oven at an elevated temperature, while tension on the web was increased until the slits necked. The necked laminate was wound up on a takeup roll. When samples were unwound, surprisingly they did not grow in width, and they showed good CD-elasticity (elongation and springback). Breathability of the laminate was superior to the laminate formed using an open niproll assembly gap.Type: GrantFiled: October 11, 1996Date of Patent: August 4, 1998Assignee: Kimberly-Clark Worldwide, Inc.Inventors: William Bela Haffner, Michael Tod Morman, Jack Draper Taylor, Jon Edward Tinsley

Patent number: 5645924Abstract: A process for weaving an elastic stretch fabric and the product thereof are provided. The fabric is woven with weft and/or warp yarns that include combination yarns which comprise a partially oriented synthetic crystalline polymer yarn combined with an elastomeric core. The fabric is then stretched, heat set and finished under particular conditions to provide the resultant fabric with an elastic stretch of 18 to 45% and dimensions about equal to the as-woven dimensions.Type: GrantFiled: September 19, 1995Date of Patent: July 8, 1997Assignee: E. I. Du Pont de Nemours and CompanyInventor: Cathy Jane Hamilton

Patent number: 5617904Abstract: A textile substrate for seat covers, a woven fabric or a knitted fabric, especially Raschel or Malimo, contains at least 40% by weight of wool and at least 15% by weight of ramie, but always more than 85% by weight of both taken together. The substrate can consist exclusively of wool and ramie but can also contain further constituents, preferably of animal or vegetable origin such as cotton, linen, hemp or else natural rubber. To obtain antistatic properties, it can contain incorporated metal threads. Minor proportions of synthetic fibres, for example polyester, are also possible. The substrate can be formed for example as a woven fabric with a blend yarn (1) of 80% by weight of wool and 20% by weight of ramie in the warp and ramie threads (2) in the weft.Type: GrantFiled: May 30, 1995Date of Patent: April 8, 1997Assignee: Rohner Textil AGInventor: Albin Kalin

Patent number: 5618595Abstract: A first air bag comprises an upper cloth and a lower cloth, the peripheries of the both cloths being connected, characterized in that the upper cloth consists of an airtight sheet obtained by weaving a composite fiber composed of a filament core and a thermoplastic polymer bonded thereto which has a melting point lower than that of said filament core, and then fusing said thermoplastic polymer so that the surface of said upper cloth has a continuous thermoplastic polymer layer. A second air bag consists of a membranous material having a breaking extension of 100% or more. A third air bag comprises an elastomer body and a shape-retaining member partially attached to the elastomer body, said member being composed of elastic fibers or threads and high-modulus fibers.Type: GrantFiled: August 25, 1994Date of Patent: April 8, 1997Assignee: Bridgestone CorporationInventors: Yosuke Matsushima, Yasuhiro Iino, Shinichi Toyosawa, Takeshi Kimura, Yoshihide Fukahori, Akeshi Noda
