SELF-CURLING NON-WOVEN SLEEVE AND METHOD OF CONSTRUCTION THEREOF

摘要

A self-wrapping nonwoven sleeve for routing and protecting elongate members and method of construction thereof is provided. The sleeve includes a non-woven wall having a thickness extending between inner and outer sides. The wall has opposite edges extending along a length of the sleeve between opposite ends. The opposite edges are biased into a self-wrapped configuration by heat-set material of the nonwoven wall to define a tubular cavity. The non-woven wall includes first and second portions extending between the opposite edges. The first portion and second portion have respective first and second thicknesses extending between the inner and outer sides, wherein the first thickness is greater than the second thickness and wherein the first portion provides flexibility to the wall and the second portion is heat set to bias the wall into its self-wrapped configuration.

主权项

1. A method of constructing a self-wrapping sleeve used to route and protect elongate members, comprising:
forming an elongate non-woven wall having a thickness extending between opposite inner and outer sides and having opposite edges extending between opposite ends of the wall; heat-setting the non-woven wall into a self-wrapped configuration to define a tubular cavity; forming at least one circumferentially extending first band portion having a first density and first thickness extending between the opposite edges; and forming at least one circumferentially extending second band portion having a second density that is greater than the first density of the at least one first band portion and a second thickness extending between the opposite edges, wherein the second thickness of the at least one second band portion is less than the first thickness of the at least one first band portion.
