SELF-WRAPPING SLEEVE AND METHOD OF CONSTRUCTION THEREOF
First Claim
Patent Images
1. A self-wrapping sleeve for routing and protecting elongate members, comprising:
- an elongate wall having opposite edges extending lengthwise along a longitudinal axis between opposite ends, said opposite edges being biased into a self-wrapped configuration about the longitudinal axis to define an internal cavity, said opposite edges being extendable away from one another under an externally applied force to expose the internal cavity for insertion or removal of the elongate members and return to their self-wrapped configuration upon removal of the externally applied force, said wall including a non-woven layer of intertwined fibers and a textile layer of interlaced filaments, wherein the non-woven layer is fixed to the textile layer via fibers of the non-woven layer being entangled with filaments of the textile layer.

Abstract
A self-wrapping sleeve and method of construction thereof is provided. The sleeve includes an elongate multilayered tubular wall having opposite edges extending along a longitudinal axis of the sleeve between opposite ends of the sleeve. The opposite edges are biased into a self-wrapping configuration about the longitudinal axis to define an internal cavity bounded by the tubular wall. The tubular wall includes a non-woven layer of intertwined fibers and a textile layer of interlaced filaments, wherein the non-woven layer is fixed to the textile layer via needled fibers of the non-woven layer being entangled with filaments of the textile layer.

11. A method of construction a self-wrapping sleeve, comprising:
-
providing an elongate non-woven layer; providing a textile layer; laying the non-woven layer and the textile layer in overlying relation with one another; needle punching the non-woven layer to entangle fibers of the non-woven layer with filaments of the textile layer to form a multilayered wall having opposite edges of the non-woven layer and the textile layer extending lengthwise between opposite ends; and heat-setting the wall into a tubular self-wrapped configuration with the opposite edges being biased into overlapping relation with one another to define an internal cavity. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
