KNIT CONVOLUTE PROTECTIVE SLEEVE

摘要

A convolute protective sleeve (40) is knitted from filamentary members (46) to form alternating crests (52) and troughs (54) lengthwise along the sleeve. The crests (52) and troughs (54) may be formed by alternatingly knitting segments from relatively stiff and relatively flexible filamentary members, by interlacing stiffening hoops (42) at spaced intervals lengthwise along a knitted sleeve having a smaller nominal diameter than the hoops (42), or by varying the knitting parameters, such as loop density and loop length as a function of length along the sleeve.
