Abstract: Tubular sleeves formed from elongated flat sheets, particularly braided sheets are disclosed. Sheet material comprised of interlaced monofilaments is cold worked by the process of drawing the interlaced monofilaments over a forming edge with sufficient force and in a direction causing permanent elongation of the molecules of material on one side of the interlaced monofilaments.

Abstract: Disclosd is a pre-expanded braided sleeving made from flexible strands of either conductive or nonconductive filaments, or a combination thereof, along with entrapped warp filaments of heat shrinkable material. The warp filament material is commonly known as heat reactive material and, when briefly subjected to heat below its fusion temperature, shrinks in the order of 30% to 50% of its length and very substantially expands the sleeving thereby greatly expediting the assembly thereof over an elongated object. Thereafter the sleeving is readily contracted into a snug fit with the object upon being tensioned between its opposite ends.

All the warp yarns extend to the large end 12. A requisite number of warp yarns 16 extend the full length of the sleeve. Other warp yarns exemplified at 18, 22, 26, 28, 30 and 32 extend from the large end but are terminated along the length of the sleeve. It is then woven with a filling yarn 40 which extends in a full circle along the full length of the sleeve to thereby define the tapered sleeve. The sleeve after fabrication is then placed on a mandrel 42, heated in an oven 44 and is thereafter placed on the arm or other limb of a space suit exemplified at 50.

Abstract: The invention relates to a tubular member, especially for safety steering columns for motor vehicles, made of wound fiber-reinforced materials. The winding angle of the fibers or fiber belts amounts to essentially .+-.45.degree. relative to the tube's longitudinal axis. For taking up high torsional moments and simultaneously low compressive and buckling or bending loads, the tubular member (1) has an expanded outwardly bulging section (3) extending around the entire circumference of the tubular member. This bulging section is preferably a double conical outward bulge. The fibers (2) cross each other at an angle of essentially 90.degree. even in the region of the outwardly bulging section (3), which means that the winding angle of essentially .+-.45.degree. to the tube's longitudinal axis is maintained in the region of the outwardly bulging section (3).

Abstract: A generally cylindrical member, such as a catheter, cannulae, or the like, has a monolithic construction. An inner core of plastic is passed through a conventional reinforcing apparatus, such as a conventional braiding mechanism. The braiding action is interrupted at predetermined intervals while the core continues to be fed so that straight reinforcing strand lengths are disposed on the outer surface of the inner core at predetermined lengths. The member passes through a heated sizing die to adhere the braided strand to the inner core, and a mechanical shear or rotating blade cuts the straight strand lengths off so that they are detached from the core. An over-extrusion of plastic may be provided to encapsulate the reinforcing strands. When the catheter is free of reinforcing strands it is relatively soft and flexible--such as at its tip--and where the reinforcing strands are provided it is relatively stiff. The monolithic construction ensures that components will not detach in a patient's body.

Abstract: An electrically insulating, overcoated bulky sleeve is disclosed comprising a tubular sleeve prepared from bulky (i.e. low density, high surface area) continuous filament yarns and an overcoating. When an electrical conductor is positioned therewithin, the large surface area of the bulky yarns of the interior of the sleeve provides an intimate fit for an expanded range of conductor diameters. For applications where a void-free impregnation of the sleeve interior between the overcoating and the conductor is desired, the large interior surface area of these sleeves can promote retention of the impregnation composition. The overcoated sleeve can be expandable, deforming to allow pull-back and return or fold-over, and/or conforming to accept transitions in conductor diameter. The overcoated bulky sleeve can be employed in a method for electrically insulating a conductor, which method may further include an interstitial impregnation step.
