Patent ID: 8627696

Claim:
A method of manufacturing a metal cable having two layers (Ci, Ce) of construction M+N, comprising an inner layer (Ci) having M core wires of diameter d 1 wound together in a helix at a pitch p 1 , M varying from 2 to 4, and an outer layer (Ce) of N wires of diameter d 2 , wound together in a helix at a pitch p 2 around the inner layer (Ci), the method comprising: assembling the M core wires by twisting to form the inner layer at a point of assembling; sheathing the inner layer with a diene rubber composition called “filling rubber” in a raw state downstream of the point of assembling of the M core wires; assembling the N wires of the outer layer by twisting the N wires around the sheathed inner layer to form the metal cable; and twist balancing the metal cable to force the filling rubber in the raw state toward a central channel of the cable.
