Abstract:
The invention relates to a method for producing a wire cable (1), wherein a core strand (3) is compacted and then braid strands (2) are stranded on the core strand (3), characterized in that the core strand (3) is hammered before stranding of the braid strands (2) in order to smooth the surface (10) thereof. A plastic layer is advantageously applied to the core strand (3) before stranding of the braid strands (2), wherein the braid strands (2) are pressed into the plastic layer (7), preferably while the plastic layer (7) is heated. In the preferred embodiment of the invention, the core strand is a core cable (3) and the braid strands are strands (2) of the wire cable (1) or the core strand is a heart strand (3) and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable (1) is obtained by hammering the core strand (3) in order to smooth it than by compacting a core strand (1) with a roller compressor. The invention further relates to the wire cable (1) and to a device for producing the wire cable (1).
Abstract:
A rope and a method of constructing the rope. The rope may be of 12 x 12 braided construction and include a core for its length. The rope includes a plurality of primary strands, and each of the primary strands includes a plurality of fibers which may be made of a high-friction material. The rope also includes a secondary strand surrounded by the plurality of primary strands. The secondary strand includes a plurality of fibers which may be made of a low-friction material.
Abstract:
The invention relates to a multi-strand metal cord (C-1) having two layers (Ci, Ce) with a J+K construction, in particular for reinforcing the tyres of industrial vehicles, consisting of a core comprising J strand(s) forming an inner layer (Ci), J varying from 1 to 4, K outer strands being helically wound around said core at a pitch P? of 20 to 70 mm, forming an outer layer (Ce) around said inner layer (Ci), each outer strand: comprising a cord (10) with two layers (C1, C2) with an L+M construction, rubberised in situ, comprising an inner layer (C1) consisting of L wires (11) with a diameter d1, L varying from 1 to 4, and an outer layer (C2) of M wires (12), M being no lower than 5, having a diameter d2 helically wound together at a pitch p2 around the inner layer (C1); and having the following characteristics (d1, d2 and p2 being given in mm): - 0.10 1 2 2
