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:
A high-elongation composite cord used for reinforcing a rubber composite such as a wheel tire and a conveyor belt. It is made by twisting a plurality of strands each made by twisting a plurality of brass-plated steel filaments and monofilaments of organic fiber. Before twisting the cord, monofilaments of organic fiber are put in the gaps formed between the adjacent strands so as to prevent fluidized rubber from penetrating into a center core formed in the cord after the cord has been covered with rubber. The monofilaments should have a diameter small enough not to protrude from a circle circumscribing the cord and large enough to close the gaps between the adjacent strands.
Abstract:
The present rope is torsion free mainly because it has an inner rope formed by an inner layer of strands which is surrounded by an outer layer of strands and since the inner rope is constructed of at least three flattened strands and at least three round strands which are smaller than the flattened strands to fill the spacings between adjacent flattened strands. The inner strands surround a center member of elastic material.

1,247,604. Vehicle tyres. GUSTAV WOLFSEIL-UND DRAHTWERKE. 13 Oct., 1969 [16 Oct., 1968; 11 June, 1969], No. 50257/69. Heading B7C. [Also in Division D1] A strand of polygonal cross-section having filaments constituting an inner lay and an outer lay, is characterized in that the outer lay filaments are arranged in groups of three associated with each inner lay filament, two of the outer lay filaments in each group being thinner than the third, the strand having no filament extending coaxial with the strand axis. In Fig. 2 there are three inner filaments 9, 10, 11 and nine outer filaments. Inner filament 9 is associated with three outer filaments 9a, 9b, 9c and filaments 9a, 9b are thinner than filament 9c. Fig. 1 illustrates an embodiment in which two inner filaments 1, 2 are associated with six outer filaments. Inner filament 1 is associated with the three outer filaments 3, 4, 5 and filaments 3, 4 are thinner than filament 5. Fig. 3 (not shown) illustrates an embodiment in which there are four inner filaments and twelve outer filaments. The Specification also describes cables made from the strands. The strands or cables may form an endless ring and may be embedded in a vehicle tyre. The filaments may be of metal, glass, plastics or any combination of these materials.
Abstract:
Elevator tension members are disclosed. The disclosed tension member longitudinally extends along a longitudinal axis and includes a plurality of fibers formed into one or more primary strands or cords extending parallel to the longitudinal axis and a plurality of fibers formed into one or more secondary strands or cords extending parallel to the longitudinal axis and through less than the full length of the belt, and a jacket retaining the primary and secondary strands or cords. The secondary strands or cords have a tensile modulus greater than a tensile modulus of the jacket and less than a tensile modulus of the primary strands or cords. Methods of making the tension member are also disclosed.
Abstract:
A cord material suitable for use in lined textile structures with a gliding component includes a plurality of uniform strands, and a deviant strand. The deviant strand is different from the uniform strands in some characteristic affecting aerodynamic or hydrodynamic properties of the cord, such as size or surface properties. Each uniform strand can have a substantially equal cross section area, while the deviant strand has a cross section area at least five times greater than one of the uniform strands. The strands can be braided or woven together. A major benefit of the material can be that vibration induced drag is significantly reduced or eliminated in lines made with the material. Another advantage is that lines made from the material can have more consistent, predictable line drag, which can improve the quality of handling.
Abstract:
A wire cable and a device and method for producing the wire cable, wherein a core strand is compacted and then braid strands are stranded on the core strand. The core strand is hammered before stranding of the braid strands in order to smooth the surface thereof. A plastic layer is applied to the core strand before stranding of the braid strands. The braid strands are pressed into the plastic layer while the plastic layer is heated. The core strand is a core cable and the braid strands are strands of the wire cable or the core strand is a heart strand and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable is obtained by hammering the core strand in order to smooth it than by compacting a core strand with a roller compressor.
