Abstract:
Elevator coated ropes or belts are disclosed. The coated rope or belt may include at least one cord and a jacket retaining the at least one cord. The cord may include a plurality of filaments. The filaments are free of second-order helical structure. In a first embodiment, the filaments includes at least one inner filament and a plurality of outer filaments surrounding the at least one inner filament. The outer filaments are bunched together by forming a first-order helical structure through the length of the cord. In a second general embodiment, the filaments are free of both first- and second-order helical structures. The filaments are bunched together by a restraining loop or adhesive at one or more locations along the length of the cord. Methods of making the tension cord are also disclosed.
Abstract:
A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52). The core element (42, 52) includes a bundle of synthetic yarns. The first metallic closed layer (44, 54) includes a plurality of first strands of wires helically twisted together with the core element (42, 52) in a first direction. The second metallic closed layer (46, 56) includes a plurality of second wires or strands helically twisted together with said core element (42, 52) and said first metallic closed layer (44, 54) in a second direction. The cross-sectional area of the core element (42, 52) is larger than the total cross-sectional area of the first (44, 54) and second (46, 56) metallic closed layers. A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.

Abstract:
From a first aspect, a method is provided for forming a helix rope for a trawl comprising the steps of: a) situating upon a portion of a rope a bead of a substance being selected from a group consisting of: (i) a liquid substance; and (ii) a semi-liquid substance. From a second aspect, a helix rope (35) is provided for forming portions of a pelagic trawl, the helix rope comprising a braided sheath (398) formed of greater than sixteen strands (397), whereby drag is reduced. From a third aspect, a method is provided for forming a high strength synthetic rope useful for towing warps, trawler warps, yachting ropes, mooring lines, anchoring lines, oil derrick anchoring lines, seismic lines, paravane lines, and any other uses for rope, cable or chain.
Abstract:
The present invention concerns hybrid layered cables some of which can be used to reinforce at least one crown protection ply of tyres for heavy vehicles or earthmovers, and others to reinforce the beads of tyres for light motorised vehicles such as motorcycles. The invention also concerns a composite fabric usable as a crown protection ply of such heavy vehicles or earthmovers, and a bead wire designed to reinforce the said beads and the aforesaid tyres. A hybrid layered cable (C) according to the invention comprises a non-metallic internal layer (Ci) and an unsaturated external layer (Ce) comprising strands (T) each of which is at least in part metallic and which are wound in helix around the said internal layer, the said cable having a relative elongation at break At, measured in tension in accordance with the standard ISO 6892 of 1984, which is higher than 7%. According to another aspect of the invention, the said internal layer is composed of at least one material having a relative elongation at break Ar at 20° C. in excess of 6%.
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 1×n 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 wire rope including a core rope having a number of strands each made of a number of wires, and a number of outer strands closed on the core rope. Each strand of the core rope has a contact section where two or more wires of the strand of the core rope come into contact with the closed outer strand. A total of contact section rates Tz is 20 percent or more of a circumference of a circumscribed circle of the core rope: Tz (%)=Ti/C.times.100, wherein Tl denotes a length of a circumferential component of the contact section, "C" denotes a length of the circumference of the circumscribed circle of the core rope. A non-contact section rate Gz is below 20 percent of the circumference of the circumscribed circle of the core rope: Gz (%)={100-(n.times.Tz)}/n, wherein "n" denotes the number of strands.
Abstract:
The cable includes a substantially metallic central core (3) and outer strands (2) formed from at least one layer of metal wires (21), particularly steel wires, which are stranded over a core element (22) made from synthetic material, preferably a thermoplastic material, this being with a pitch similar to that of the strands (5,6) with which the core (3) is formed, it being possible for the latter to be entirely metallic or hybrid. These cables are intended particularly for use as a lifting cable, particularly elevator cables, or other multicable installations with transmission by means of adherence.
Abstract:
Reinforced thermoplastic impregnated lubricated wire ropes are provided in the present invention. A method of reinforcing and filling the thermoplastic material with fibers, mineral fillers and powders is also provided.
Abstract:
A non-rotating rope, comprising 3 or 4 strands of of clam-shaped cross section so arranged around a flexible core equidistantly from the rope center that the principal axes of the clams are on the equiangularly spaced radial lines radiating from the rope center and the sides of the clams are in contact with one another with the apex and base of each clam directed inwards and outwards respectively, is closed in a direction opposite to the direction of the lay of the strands.
