  • Patent number: 5312645
    Abstract: A web is fabricated by coating at least one layer of thermoplastic material, pigmented polyurethane, onto a transparent polyester plastic film. The resulting web can readily be cut by a computer controlled blade to produce virtually any graphic pattern, including intricate or small letters that may be connected or separated from each other, without penetration of the blade through the carrier sheet. The graphic sheet adheres strongly enough to the carrier sheet, with a peel value in the range of 15-30 ounces, to prevent sliding of the graphic sheet relative to the carrier sheet during cutting, yet permitting release of the carrier sheet after attachment of the graphic by the application of heat and pressure. Thus, the present invention provides an "adhesive up" type of web for polyurethane graphics, whereby the graphic can be cut and peeled from the web, and the graphic, while still adhered to the carrier sheet, placed against the fabric.

  • Patent number: 4729908
    Abstract: A decorative web or sheet of plastic material is obtained by spraying plastic material of different color and/or structure onto a carrier web by means of nozzles, the carrier web and the nozzles being movable in relation to each other, such that the nozzles can be placed over different, predetermined areas of the carrier web. The relative movement is controlled by means of a computer programmed with the desired web or sheet pattern. A suitable installation for carrying out the method has means for transporting the carrier web in one direction and carries nozzles which are movable parallel to the carrier web in two planes at right angles to each other. By means of the nozzles, plastic material is sprayed onto the carrier web in predetermined areas and to the desired thickness.
