Abstract:
1. A knit tubular sleeve for providing abrasion resistance and expansion restriction to an elongate member extending therethrough, comprising: a knit tubular wall extending along a longitudinal axis between opposite ends, said wall having a plurality of coaxially aligned first regions forming crests spaced axially from one another by intermediate second regions forming troughs between said crests, said first and second regions being knitted over a plurality of courses, each of said courses comprising a plurality of knit stitches extending circumferentially around said longitudinal axis, said courses of said first regions being formed with knit stitches of a different stitch pattern from said courses of said second regions and thereby providing said second regions with a decreased capacity to expand radially relative to said first regions, wherein said second regions include missed-stitches; and wherein said crests formed by said first regions extend from radially innermost courses adjacent said troughs to radially outermost courses forming peaks, said knit stitches of said peaks having stitch lengths greater than said knit stitches of said radially innermost courses.
