Abstract: A climbing rope composed of a core of strands surrounded by a braided tubular sheath, whereby the tightness of the sheath determines the stiffness of flexibility of the rope. Most of the rope is flexible because its sheath is loose, while, near its end intended for creating the tying knot, there is a stiff section, i.e., a section whose sheath is tighter than along the rest of the rope. The stiff section is abrasion resistant where the climbing rope passes through the piton closest to the climber.

Abstract: Fiber reinforced plastic tubing is formed by an innermost layer of braided strands that include longitudinal stud fill strands within the braid, a second layer of longitudinal strands, and a third layer of braided strands, all thoroughly encased in a monolithic mass of plastic matrix material that is not, itself, divided into layers. The tube is fabricated on a continuous basis by winding two sets of strands in opposite directions on a mandrel and braiding the two sets with each other and with stud fill strands that prevent that first layer of braid from stretching longitudinally and thereby tightening immovably on the mandrel. The strands are braided dry but are wetted with liquid plastic matrix material as the braid is compacted on the mandrel.

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: 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.
