Two-layer (Ci, Ce) metal cable (C-1) of (3+N)-construction, rubberized in situ, comprising an inner layer (Ci) consisting of three core wires of diameter dwound together helically with a pitch pand an outer layer (Ce) of N wires, N varying from 6 to 12, of diameter dwound together helically with a pitch paround the inner layer (Ci), said cable being characterized in that it has the following features (d, d, p, pbeing in mm): 0.08<d<0.30; 0.08<d≤0.20; p/p≤1; 3<p<30; 6<p<30; the inner layer is sheathed in a diene rubber composition termed the "filler rubber" which, for any 2 cm or greater length of cable, is present in the central channel formed by the three core wires and in each of the interstices between the three core wires and the N wires of the outer layer (Ce); the filler rubber ratio in the cable being between 5 and 35 mg per 1 g of cable. Multistrand cable comprising at least one two-layer cable according to the invention, intended particularly for tyres for industrial vehicles of the civil engineering type. |
