Abstract:
Disclosed herein is a wraparound closure device which includes an axially compressible, radially expansible tubular member which is made from a fabric of engineering plastic. The member is axially split to define a first and a second mating edge. Fastening means are connected to the mating edges for selectively opening and closing the member. The fastening means is fixed in length and thereby when it is connected to the tubular member, the tubular member is also fixed in length. However, the tubular member remains radially variable and expands and contracts to adapt to the shape of a substrate to be enclosed. Also disclosed herein is a method for making such a device.
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:
a braided sleeve is formed from a tow of flexible filaments such as glass fibers and a rigid filament such as a stainless steel wire. The rigid filament reduces the tendency of a braided sleeve to fray at its ends, and can cause the end portions of the sleeve to taper inwardly, which can enhance the thermal insulation properties of the sleeve. The sleeve may be coated with polymeric material.
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. A product so formed snap fits over an elongated substrate without the need for other attaching means. Sleeve products may have a circular, rectangular, square or triangular cross-section or various combinations of these cross-sections.
Abstract:
This invention provides a woven tubular gasket having a continuous integral attachment means which is contained within the woven tubular members and which has protrusions which extend through or are extendable through the walls of the woven tubular member or members and are adapted to engage openings in an appropriate surface or substrate on which the gasket is to be attached. The method of this invention provides for continuously forming the combination of the attachment means and the woven tubular member. The attachment means is fed continuously into the interior of the woven tubular member as it is formed to thereby incorporate the attachment means into the interior of the woven tubular member.
