  • Patent number: 9062396
    Abstract: A knit tubular sleeve for providing abrasion resistance and expansion restriction to an elastic elongate member extending therethrough and method of construction thereof is provided. The knit tubular sleeve includes a knit tubular wall extending along a longitudinal axis between opposite ends. The knit wall has a plurality of coaxially aligned first regions forming crests spaced axially from one another by intermediate second regions forming troughs between the crests.

  • Patent number: 5085252
    Abstract: Method of weaving a variable cross-sectional shaped three-dimensional fabric which utilizes different weft yarn insertion from at least one side of the warp layers for selectively inserting weft yarns into different portions of the fabric cross-sectional profile defined by the warp yarn layers during the weaving process. If inserted from both sides of the warp yarn layers, the weft yarns may be inserted simultaneously or alternately from each side of the warp yarn layers. The vertical yarn is then inserted into the fabric by reciprocation of a plurality of harnesses which separate the vertical yarn into a plurality of vertical yarn systems as required by the shape of the three-dimensional fabric being formed.
