  • Pre-expanded braided sleeving
    Patent number: 4777859
    Abstract: Disclosd is a pre-expanded braided sleeving made from flexible strands of either conductive or nonconductive filaments, or a combination thereof, along with entrapped warp filaments of heat shrinkable material. The warp filament material is commonly known as heat reactive material and, when briefly subjected to heat below its fusion temperature, shrinks in the order of 30% to 50% of its length and very substantially expands the sleeving thereby greatly expediting the assembly thereof over an elongated object. Thereafter the sleeving is readily contracted into a snug fit with the object upon being tensioned between its opposite ends.
    Type: Grant
