  • Apparatus for extruding a low density thermoplastic foam
    Patent number: 5728406
    Abstract: An apparatus are described for extruding a soft, low density elastomeric thermoplastic foam. A single screw extruder having a very large screw length to diameter ratio is provided to thoroughly mix the thermoplastic elastomer with a blowing agent. A thin, substantially taperless die is also provided to form extruded profiles. By using such an apparatus, a variety of complex-shaped extruded profiles may be easily produced.
    Type: Grant

  • Method and apparatus for coating a substrate with a liquid resin
    Patent number: 5192586
    Abstract: A method and apparatus of applying a coating to a substrate is provided. A liquid resin is introduced into a first region at a predetermined pressure. The liquid resin is maintained within a first pressure range in the first region. Next, the flow of the resin from the first region to a second region is controlled so as to bring the resin from the first pressure range to a second pressure range, the pressures in the second pressure range being lower than the pressures in the first pressure range. The liquid resin is then applied at a pressure within the second pressure range to the substrate at a third region adjacent the second region.
