Abstract:
1. A multi-layer cable having a unsaturated outer layer, usable as a reinforcing element for a tire crown reinforcement, comprising a core (C 0 ) of diameter d 0 surrounded by an intermediate layer (C 1 ) of six or seven wires (N=6 or 7) of diameter d 1 wound together in a helix at a pitch p 1 , this layer C 1 itself being surrounded by an outer layer (C 2 ) of P wires of diameter d 2 wound together in a helix at a pitch p 2 , P being less by 1 to 3 than the maximum number P max of wires which can be wound in one layer about the layer C 1 , this cable being characterised in that it has the following characteristics (d 0 , d 1 , d 2 , p 1 and p 2 in mm): (i) 0.28≦d (ii) 0.25≦d (iii) 0.25≦d (iv) for N=6: 1.10<(d (v) 5.3π(d (vi) the wires of layers C
