Patent number: 4336289Abstract: A product and method for making a patterned area in a pile rug in which pile yarn is carved out and removed to form a trough-like area, and one or more fabric pattern pieces having a total area and shape coinciding with the carved out trough-like area is inserted into the trough-like area and adhesively bonded in place. The top surface of the fabric pattern piece is distinct in either color, texture, material, or pattern from the main pile surface to produce contrasting patterns in the surface of the rug. The fabric pattern piece may be a separate pile strip including its own base fabric and pile yarn of different color, texture, material, height, or other distinguishing characteristics from the pile yarn of the main body of the rug. The method is particularly adapted for forming linear patterned insert pieces along the borders of an area pile rug.Type: GrantFiled: July 6, 1981Date of Patent: June 22, 1982Inventor: Edward L. Davis

Patent number: 4307140Abstract: A laminated article comprising a plurality of abrasive resistant ceramic tiles secured to an elastomeric polyurethane cushioning support by means of a multitude of short thin fibers having major portions thereof embedded within an epoxy resin bonded to the tiles is fabricated by applying a thin layer of the resin in an uncured liquid phase to the tiles, applying a coating of the fibers to the liquid resin such that minor portions of the fibers in contact with the resin are wet thereby and the remaining major portions of the fibers extend from the resin layer, curing the resin to secure the fibers therein and to bond the resin to the tiles, applying a layer of a thermosetting polyurethane in an unpolymerized liquid phase to the fiber impregnated resin layer, and thereafter curing the polyurethane layer.Type: GrantFiled: July 31, 1980Date of Patent: December 22, 1981Inventor: Thomas E. Davis

Patent number: 4293603Abstract: A method of making a laminate and articles of furniture made from the laminate are disclosed wherein a transparent acrylic sheet is coated with an acrylic paint coating composition on one side in a predetermined color and decorative pattern. The coated sheet is then coated with an acrylic primer coating composition over the acrylic paint coating. The sheet is adhesively secured to a backing member such as barrel board for fabrication into furniture. Preferably, abrasion-resistant or super abrasion-resistant coated acrylic sheets are used and the side coated with acrylic paint and lacquer is that opposite the abrasion-resistant coated side.Type: GrantFiled: January 9, 1980Date of Patent: October 6, 1981Inventors: Charles R. Hayman-Chaffey, Frederick W. Hayman-Chaffey

Patent number: 4282051Abstract: A latent pressure-sensitive fastener having a discontinuous surface is made by spraying an aqueous pressure-sensitive adhesive onto a flocked pile surface which is adhered to a substrate by a permanent adhesive. The flocked pile surface serves as a reservoir for the pressure-sensitive adhesive. The pressure-sensitive adhesive is wicked towards the face of the flocked pile surface upon face-to-face mating of two fasteners. The reservoir of pressure-sensitive adhesive and the wicking action enables repeated fastening and unfastening of two mated fasteners without loss of locking power. The fasteners are particularly useful for seaming carpets.Type: GrantFiled: March 6, 1980Date of Patent: August 4, 1981Inventor: John M. Terpay

Patent number: 4239829Abstract: An adhesive bonding method and apparatus includes a pair of opposed web members having confronting surfaces provided with cooperatively engaging hook and loop portions. The hook portion of one confronting surface is saturated with an epoxy resin or the like, and the loop portion of the other confronting surface is saturated with a catalyst for the resin. The web members are urged together to engage the hook and loop portions and to intermix the catalyst and the resin.Type: GrantFiled: February 4, 1980Date of Patent: December 16, 1980Inventor: Howard S. Cohen
