Abstract: A split sleeve for insulation of heat generating components, such as an exhaust gas recirculation device, comprises an outer layer of knitted woven or braided glass fiber yarn. A first metal wire skeleton or frame in the form of a continuous wire support for the outer layer is bent in a first step with a series of reverse bends to form a comb-like structure and in a second step to a C-shaped cross-sectional configuration in which the wire defines a cavity and the wire bends define an opening extending lengthwise of the cavity. A layer of heat insulating mineral paper is spaced from the cover layer by the metal wire skeleton. The heat insulating mineral paper is provided with a metal foil layer on the side away from the metal wire skeleton. A second metal wire layer configured like the first extends lengthwise of the sleeve and spaces the reflective surface of the foil from the heat generating component.

Abstract: A sleeving product and a method for making a sleeving product suitable for use as a barrier for resisting heat transfer between an external heat source and an elongated substrate, comprising: a tubular layer comprising a flexible, resilient foamed insulating material; and an exterior cover layer bonded to one surface of the tubular layer, the cover layer comprising a metalized polymeric film, the metalized polymeric film comprising a flexible polymeric film and a nonporous, thin coating of heat reflective metal applied to at least one surface of the polymeric film.

Abstract: Wraparound sleeves formed by weaving, knitting or braiding for the protection of elongated articles, such as cables and hoses, are disclosed. The tubes are provided with closure means comprising multifilament, bulky yarn interlaced in the sleeving material and relatively unconfined along one of its marginal edges and of Velcro brand hook tape or similar hook type elements disposed along the other marginal edge.

Abstract: Sleeves of braided monofilament formed resilient materials are fabricated incorporating flexible, nonresilient (i.e. limp) multifilament warp yarns. Monofilaments are braided from strands of high modulus engineered plastic materials to provide enhanced pushback and springback propeties in sleeves formed of the braided material. Yarns, such as, spun or texturized yarns, impart body, coverage, and improved tensile strength without sacrificing springback properties. "Loopies", which are characteristic of monofilament warps, are avoided.

Abstract: Wraparound sleeves formed by weaving, knitting or braiding for the protection of elongated articles, such as cables and hoses, are disclosed. The tubes are provided with closure means comprising multifilament, bulky yarn interlaced along one marginal edge of the sleeving material and of Velcro hook tape or other hook type elements disposed along the other marginal edge. In one embodiment of the invention, the interlaced multifilament, bulky yarn is disposed along both marginal edges with the Velcro tape fastened to one side of the bulky yarn on one marginal edge. Intermediate bands or rows of multifilament yarn may be provided so that to accommodate bundles of irregular cross-sectional tape. When the sleeving material is provided in rolls, the hooks on one side of the web interengage with the bulky multifilament yarn surface exposed on the other side of the web so that the web is held in rolled up form except when deliberately unwrapped.

Abstract: Tubular sleeves of braided, knited or woven construction comprised of bulky continuous filament yarns and a resilient engineered plastic monofilament have excellent noise reduction characteristics. The bulky yarn provides a flexible cushion for cables and tubes covered by the sleeves thereby reducing vibration induced wear. The resilient monofilament gives the sleeve material sufficient hand so that sleeves formed according to the invention tend to assume the open position without loss of the ability to deaden sound and cushion vibration.

Abstract: Sleeves formed of fabrics comprised wholly or in part from engineered plastic materials which are settable by heat to be biased to a specific sleeve geometry are disclosed. One form of sleeve illustrated involves heat-setting plastic material to a helical configuration by wrapping an elongated strip of the fabric material helically on a mandrel, heating the material while in the helical configuration, and thereafter cooling the material so that is has a permanent helical set with the side edges of the material in overlapping relation. the sleeves so formed may be collapsed into a short cylinder for packaging. In use, the compressed cylinder is allowed to expand lengthwise over an elongate object or objects to effect a jacketing of the same without additional assembly effort. A second form of sleeve disclosed involves setting the fabric material in tubular form, wherein the product is formed to have side edges abutting one another or in overlapping relation.

Abstract: This invention provides a fabric for RFI/EMI shielding wherein the fabric is woven, braided or warp knitted from yarns which comprise conductive fibers and non-conductive fibers wherein the conductive fibers comprise from about 10% to about 80% by weight of the fabric.
