摘要:
A two-layer multi-strand metal cable (10) comprises: - an inner layer (C1) of the cable (10) made of K>1 inner strands (Tl) wound in a helix, - an unsaturated outer layer (C2) of the cable (10) consisting of L>1 outer strands (TE) wound in a helix around the inner layer (C1) of the cable (10). Each inner and outer strand (Tl, TE) of the cable (10) comprises: - an inner layer of the strand (Tl, TE) made of 2 inner wires, and - an outer layer of the strand (Tl, TE) consisting of N outer wires wound in a helix around the inner layer of the strand (Tl, TE).

Resilient metal/textile composite cord (C-I) comprising two layers (Ci, Ce) of 1+N construction, which is formed from a cord or internal layer (Ci) comprising a textile core yarn (10) of diameter d1, and a metal external layer (Ce) of N wires (12) of diameter d2 wound together in a helix with pitch p2 around the layer Ci, said cord being characterized in that it has the following characteristics (p2 in mm) :-As > 1.0 % ; At > 4.0 % ; Af > 6.0 % ; d1 > 1.1d2 ; 4
摘要:
The inventive two-layer 4+N structured wire rope comprises an internal layer C1 consisting of 4 wires with a diameter d1 which are jointly helically wound with a pitch p1, wherein said layer C1 is also surrounded with an external layer C2 consisting of N wires with a diameter d2 which are jointly helically wound with a pitch p2. Said wire rope is characterised in that it exhibits the following characteristics (d1, d2, p1 and p2 in mm): - 0,25
摘要:
The invention relates to a three-layer metal cord of L+M+N construction, which can be used to reinforce a tyre carcass reinforcement. The inventive cable comprises: an inner layer C1 with L wires having a diameter d1, L varying between 1 and 4; an intermediate layer C2 which surrounds the inner layer, with M wires having a diameter d2, which are helically wound together with a pitch p2, M varying between 3 and 12; and an outer layer C3, which surrounds the intermediate layer C2, with N wires having a diameter d3, which are helically wound together with a pitch p3, N varying between 8 and 20. The cord is characterised in that a sheath, which is made from a crosslinkable or crosslinked rubber composition based on at least one diene elastomer, covers at least the aforementioned intermediate layer C2. The invention also relates to the plastic and/or rubber semifinished products or articles reinforced with one such multilayer cord, such as tyres that are intended for industrial vehicles and, more specifically, heavy vehicle tyres and the carcass bracing plies thereof.
