摘要： Method for manufacturing a metal cable comprising two layers (Ci, Ce) of M+N construction, made up of an inner layer (Ci) consisting of M wires of diameter d1 wound together in a helix with a pitch p1, M varying from 2 to 4, and an outer layer (Ce) of N wires of diameter d2 wound together in a helix with a pitch p2 around the inner layer (Ci), said method comprising at least the following steps, carried out in line: an assembly step, in which the M core wires are twisted together so as to form the inner layer (Ci) at a point of assembly; downstream of said point of assembly of the M core wires, a sheathing step, in which the inner layer (Ci) is sheathed with a diene rubber composition called “filling compound” in the uncured state; an assembly step, in which the N wires of the outer layer (Ce) are twisted together around the inner layer (Ci) thus sheathed; and a final twist balancing step. Device for implementing such a method.

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.
