Abstract
A sleeve having a longitudinally extending slit for covering wires or tubing is provided with a support layer of a continuous monofilament of formable metal wire or heat-settable monofilament formed into a multiplicity of spaced apart reversely bent crests and troughs. The continuous monofilament is bent to form a split tube having the crests and troughs in facing relationship. At least one outer layer is provided on said support layer. The outer layer may be an insulator such as a metal foil or metalized film, an abrasion-resistant material or a resilient sound-absorbing material. Inner layers may comprise insulating materials and/or felts, foams or other sound-absorbing materials. Various closure means for closing the longitudinal opening formed at the slit are disclosed.
Claims14
A flexible sleeve for the protection of elongated articles comprising:
- a supporting frame having longitudinal flexibility and lateral rigidity, said supporting frame layer comprising a stiff, formable, continuous monofilament member extending lengthwise of the sleeve, said monofilament member being formed into a plurality of spaced, generally parallel runs, each run being joined at one end by a reverse bend to the beginning of the next adjacent run, the generally parallel runs of said continuous monofilament member being formed about an axis extending lengthwise of the sleeve to assume a generally C-shaped cross-section to define an axially extending interior region;
- a flexible inner layer of sound absorbing material, said inner layer being located interiorly of supporting frame layer;
- and
- an outer cover layer of flexible material separate from the supported frame layer, said cover layer surrounding and being supported by said supporting frame layer, said outer cover layer being substantially co-extensive in length with said supporting frame layer.
