Abstract:
The abrasion resistance of organic fiber based ropes and cords is increased by a outer woven cover of tapes of high molecular weight and more preferably ultrahigh molecular weight polyethylene.
Abstract:
A combined cable comprising a core cable of high-strength synthetic fibers, which take the form of a twisted bundle of monofilaments or a plurality of twisted bundles of monofilaments, and comprising an outer layer of steel wire strands, is characterized in that the bundle or bundles of monofilaments is or are stretched, with a reduction in diameter, and held in this state by a sheathing, in particular a braided sheathing. The extension under strain of the core cable under load is thereby reduced, so that the load distribution between the cross section of steel and the cross section of synthetic material of the cable improves.In order, in the same sense, conversely to make the strain behavior of the layer of strands approximate that of the core cable, the cable has an intermediate layer of an elastic synthetic material into which the steel wire strands are pressed while spaced apart from one another in such a way that the outer layer extends under load, and contracts radially.A strand can be analogously constructed.
Abstract:
A steel cord comprises a metal core strand and adjacent layer of steel elements. Between the metal core strand and adjacent layer of steel elements, a polymer layer with a minimum thickness of more than 0.02 mm is provided. These steel cords are to be used to reinforce off-the-road tires or conveyor belts.
Abstract:
A reinforcing structure designed for handling compression stress states when the structure is molded into a composite. The structure, specifically a wrapped cord with metallic filaments contained therein, is suitable for both compression and tension load forces. The reinforcing structure has a core comprising a plurality of essentially straight, nested filaments arranged in parallel, the filaments forming a line of contact with adjacent filaments that extends along the length of the filaments. Wrapped about the core is at least one helically wound wire.
Abstract:
A reinforcement for a building works structure comprising an assembly of solid wires. The wires are mutually parallel to form a bundle and the reinforcement comprises a sheath made of plastic material enclosing the bundle and providing it with cohesion.
Abstract:
A composite cord is provided which is simple in manufacture, highly productive, less costly, and improved in rubber penetration. The composite cord has a 1nulln construction (n is an integer from 3 to 12) with 2 to 11 metallic filaments and 1 to 5 polymer fibers having a melting point of 50 to 200 degrees twisted together. The pneumatic tire employing this composite cord for its reinforcing element is restricted in rust formation and improved in strength retention.
Abstract:
A method and machine for manufacturing and laying a plurality of elongate elements into an umbilical is shown. The umbilical comprises a core element a plurality of conduits and/or cables suited outside the core element, filler material around and between the conduits/cables and a protective sheath surrounding the conduits and filler material. The finished cable cord is characterized in that the filler material is in the form of inner, elongate channel elements having outwardly opening channels, adapted for receipt of the conduits/cables, and outer, elongate channel elements having inwardly opening channels adapted for receipt and final enclosure of the conduits/cables.
