Patent number: 5198300Abstract: A heat bond seaming tape has a base formed of a strip of paper or paper-like material. A strip of an open mesh material is adhered to the base strip and is disposed in substantially symmetrical, overlying relation thereto. A plurality of spaced, transversely disposed, rigid bracing members are sandwiched between the mesh strip and base strip or in the alternative are secured on top of the mesh strip. A thermoplastic adhesive overlies the open mesh strip and the bracing members for adhering the strip and bracing members to the backs of adjacent carpet edges, so that a seam defined by said adjacent carpet edges, will lie flat in response to the provision of said seam tape, due to the rigid bracing members extending generally transversely across the carpet seam.Type: GrantFiled: August 8, 1991Date of Patent: March 30, 1993Inventors: James Matthews, Nicholas H. Shaheen, Jr.

Patent number: 5190818Abstract: The adhesive composition of the invention exhibits an adequately controlled adhesive bonding strength when paper sheets coated therewith are bonded together to be adaptable to subsequent separation of the bonded sheets of paper by peeling. The essential ingredients of the adhesive composition include: (a) a rubber latex; (b) a silica gel powder having a specified average particle diameter; and (c) a starch, preferably, having a specified particle diameter, e.g. wheat starch, each in a specified weight proportion. In addition to the good balance between the reliability of the adhesive bonding and subsequent peelability, the paper sheet coated with the adhesive composition is prevented from a decrease in the adhesiveness even when the surface is contaminated with a silicone oil and from the troubles due to blocking when adhesive-coated sheets are stacked one on the other with the adhesive-coated surfaces in direct contact with each other.Type: GrantFiled: March 21, 1991Date of Patent: March 2, 1993Assignee: Toppan Moore Co., Ltd.Inventor: Tsutomu Sakai

Patent number: 5169701Abstract: A fabric or leather backing is employed for mounting and supporting a three-dimensional decoration composed of material such as Latex, plastic, rubber or the like. The decoration terminates at its backside of rear with a continuous edge on which an attachment flange is provided followed by placing a first bead of flowable, bondable or adhesive material thereon optionally followed by placing a second bead when the first bead has somewhat cured. The first and/or second bead is impregnated into the fabric or leather backing. Curing occurs within a specified period of time at a specified temperature range. Bonding of the decoration is complete after adhesive curing.For vinyl or other plastic material, no adhesive is used. The plastic material that the decoration is made of becomes the adhesive through a melting process. The melting point of vinyl and many other plastics are less than the burning or damaging point of the material a garment is made of such as cotton.Type: GrantFiled: June 3, 1991Date of Patent: December 8, 1992Inventor: Gregory R.
