Abstract: A method is disclosed of splicing together two rope lengths each of which is made up of a plurality of strands individually covered with thermoplastic material. Each alternate strand of each rope length is unwound back to a predetermined point and one of the strands of the other rope length is wound in its place back to that point. This process is repeated for each of the other strands, with the respective points at which the winding and unwinding process is terminated being spaced apart along the length of the splice with respect to each other. At each of these points, the end regions of the two strands of each pair at that point are placed together and then bonded together by means of their coverings of thermoplastic material. An outer covering of thermoplastic material may then be placed over the entire splice.

Abstract: A cable comprises at least one layer of strands (10) with each strand covered with an individual sheath (20) of rubber or plastics material. The sheaths are so shaped (16, 17, 18) that the sheaths of adjacent strands interlock. This provides a layer in which the strands have a generally fixed spatial relationship both to each other and within the cable. This reduces inter-strand forces, so increasing cable life, and also provides a dimensionally stable cable.
Abstract translation: 电缆包括至少一层绞线(10),每条绞线被橡胶或塑料材料的独立护套(20)覆盖。 护套是如此成形(16,17,18),使得相邻股线的护套互锁。 这提供了一个层,其中股线彼此之间和电缆内部具有大致固定的空间关系。 这减少了股间力,从而增加了电缆寿命,并且还提供了尺寸稳定的电缆。

Abstract: PCT No. PCT/GB78/00019 Sec. 371 Date June 5, 1979 Sec. 102(e) date June 1, 1979 PCT Filed Oct. 3, 1978 PCT Pub. No. W079/00182 PCT Pub. Date Apr. 19, 1979The invention relates to wire ropes.There is disclosed a wire rope comprising a plurality of strands (4-12) twisted together with each strand (4-12) being individually covered by a respective sheath (16) of rubber or rubber substitute. Each strand (4-12) comprises a plurality of wires (14) twisted together with the direction of twist of at least the outer wires (14) in each strand (4-12) being opposite to the direction of twist of at least the outer wires (14) in the strands (4-12) adjacent to it, the rope having an outer covering sheath (18) of rubber or rubber substitute.In this way, the wires (14) of adjacent strands (4-12) do not cross each other, and stress on them is reduced.
