Abstract
Method of manufacturing a metal cable having two layers (Ci, Ce) of construction M+N, comprising an inner layer (Ci) having M wires of diameter dwound together in a helix at a pitch p, M varying from 2 to 4, and an outer layer (Ce) of N wires of diameter d, wound together in a helix at a pitch paround the inner layer (Ci), the method comprising the following steps performed in line: a step of assembling the M core wires by twisting to form the inner layer (Ci) at a point of assembling; downstream of the point of assembling of the M core wires, a step of sheathing the inner layer (Ci) with a diene rubber composition called 'filling rubber', in the raw state; a step of assembling the N wires of the outer layer (Ce) by twisting around the inner layer (Ci) thus sheathed; and a step of twist balancing. Also disclosed is a device for implementing such a method.
