  • Method of making protective sleeve with warp spacers
    Patent number: 5671649
    Abstract: A braided product and process include a first sleeve formed of interbraided first and second yarns which may be continuous E glass yarns. Warp beads formed by knitting or braiding are equidistantly spaced around the circumference of the braid and introduced to the braider to form an integral part of the structure. One or more heavy denier yarns are loaded on carriers so as to cross the warp beads under relatively high tension, forcing the beads selectively to the inside or outside of the sleeve surface so as to create longitudinally extending spacers which create air gaps between the sleeve and the surface of the substrate being covered.
    Type: Grant
    Filed: March 28, 1996
    Date of Patent: September 30, 1997
    Assignee: Bentley-Harris Inc.
