Tack Strip Making Patents (Class 470/158)
  • Patent number: 7828664
    Abstract: An upholstery tack strip includes a metal ribbon and a thermoplastic sleeve covering at least a portion of the ribbon. The sleeve includes at least one, and possibly a pair of, lengthwise removed strip section(s) so as to expose a corresponding lengthwise surface of the metal ribbon. The metal ribbon integrally includes nail sections which protrude outwardly from said tack strip. At least one, and preferably both, lateral edges of the metal ribbon are knurled or serrated so as to assist in anchoring the ribbon to the sleeve.

  • Patent number: 6537646
    Abstract: An upholstery tack strip includes a thermoplastic sleeve and a metal ribbon embedded within the sleeve. The sleeve itself includes a plurality of removed material sections forming opposed pairs of sleeve windows, while the metal ribbon integrally includes nail sections which protrude outwardly from the tack strip through respective ones of the sleeve windows. Most preferably, the sleeve is extrusion-coated onto the metal ribbon stock using a cross-head die. The thus-coated metal strip preform may then be transferred to downstream fabrication operations whereby the sleeve windows and nail portions are formed. Since the nail portions protrude outwardly from the tack strip through the sleeve windows, relative lengthwise slippage between the metal ribbon stock and the sleeve is prevented.
