  • Patent number: 4123313
    Abstract: Apparatus for manufacturing a composite fabric, including an endless carrier belt having a non-stick surface and traversible over first and second contiguous sets of planar support surfaces. Heating means are provided for heating the first set of planar support surfaces and cooling means for cooling the second set of planar support surfaces. A first means is provided for supplying a relatively thick substrate to the carrier belt in advance of the first set of planar support surfaces which means includes a device for applying deaerated thermo-plastics material in liquid form directly to the surface of the carrier belt. A second means supplies pile-forming material and a third means is arranged to receive the pile-forming material that includes a lick roller for coating one surface of said pile-forming material with plastics material in liquid form.

  • Patent number: 4059465
    Abstract: To form carpet tiles that lie flat, a layer of thermoplastic material is doctored onto a carrier sheet and a piece of carpeting to be coated is laid on the layer. The carpet piece has dimensions slightly larger than the desired carpet tile. Heat is applied to the layer to bond the layer of thermoplastic material to the carpet piece and the bonded layer and carpet piece are cooled so as to form a coated carpet piece. The carrier sheet is then stripped from the coated carpet piece and waste is trimmed from the periphery of the bonded carpet piece so as to form a carpet tile. The carrier sheet is supported on a substantially flat surface during the heating and cooling steps so that the carpet piece is maintained in a substantially flat and relaxed condition and the warps and wefts of the carpet piece do not support the weight of the carpet piece.

  • Patent number: 3949443
    Abstract: A coin controlled golf ball washer having a liquid-tight enclosure arranged for containing a bath of a cleaning solution, and a drum rotatably mounted in the enclosure immediately adjacent the bath and provided with an opening arranged for permitting placement of golf balls into and withdrawal of the balls from the drum. A coin controlled motor selectively rotates the drum for causing solution to be transferred from the bath into the drum by a carrier arrangement associated with the drum, and for tumbling the golf balls to be cleaned against scouring brushes arranged within the drum.
