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 self-wrapping nonwoven sleeve for routing and protecting elongate members, comprising:
an elongate non-woven wall having inner and outer sides with a thickness of said wall extending across said inner and outer sides, said wall having opposite edges extending along a longitudinal axis of said sleeve between opposite ends of said sleeve, said edges being biased into a self-wrapped configuration about said longitudinal axis to define a tubular cavity, said edges being extendable away from one another under an externally applied force to expose said cavity for insertion or removal of the elongate members and returning to their self-wrapped configuration upon removal of the externally applied force; and said non-woven wall including at least one circumferentially extending first band portion extending between said edges and at least one circumferentially extending second band portion extending between said edges, said at least one first band portion having a first thickness extending between said inner and outer sides and a first density and said at least one second band portion having a second thickness extending between said inner and outer sides and a second density, said first thickness being greater than said second thickness and said first density being less than said second density.
