  • Publication number: 20090294009
    Abstract: Elastic metal/textile composite cord (C-1) having two layers (Ci, Ce) of 1+N construction, formed from a core or inner layer (Ci) comprising a textile core thread (10) of diameter d1 and a metal outer layer (Ce) of N wires (12) of diameter d2 wound together in a helix with a pitch p2 around the layer Ci, said cord being characterized in that it has the following characteristics (p2 in mm): As>1.0%; At>4.0%; Af>6.0%; d1>1.1d2; 4<p2<14; and the core thread (10) is a textile fibre and is embedded in a sheath (11) of diene elastomer composition, As being the structural elongation of the composite cord, At its total elongation at break, and Af being the elongation at break of the textile fibre. Use of such a cord for the reinforcement of tires, for example in the belt of these tires.

  • Publication number: 20090101266
    Abstract: A compact metal cable having two layers (C1, C2) of construction 1+N, rubberized in situ, usable in particular as a reinforcing element for a tire belt for a heavy industrial vehicle, comprising a core or inner layer (C1) comprising a single core wire of diameter d1, and a saturated outer layer (C2) of N wires of diameter d2 wound together in a helix at a pitch p2 around the layer C1, said layered cable being characterized: in that it has the following characteristics (d1, d2, p2 in mm): 0.15<d1<0.50; 0.15<d2<0.50; 8<p2<25; and in that the core wire is surrounded by a sheath of diene rubber which fills, at least in part, the gaps between the core wire and the cords of the layer C2.

  • Publication number: 20060237110
    Abstract: The present invention relates to a three-layered metal cable of construction L+M+N usable as a reinforcing element for a tire carcass reinforcement, comprising an inner layer C1 having L wires of diameter d1 with L being from 1 to 4, surrounded by an intermediate layer C2 of M wires of diameter d2 wound together in a helix at a pitch p2 with M being from 3 to 12, said layer C2 being surrounded by an outer layer C3 of N wires of diameter d3 wound together in a helix at a pitch p3 with N being from 8 to 20, said cable being characterised in that a sheath formed of a cross-linkable or cross-linked rubber composition based on at least one diene elastomer covers at least said layer C2. The invention furthermore relates to the articles or semi-finished products made of plastics material and/or rubber which are reinforced by such a multi-layer cable, in particular to tires used in industrial vehicles, more particularly heavy-vehicle tires and their carcass reinforcement plies.

  • Patent number: 7089726
    Abstract: A cable is disclosed that can be used to reinforce a crown protection ply and/or a stiffener (9) in tires for heavy industrial vehicles. Also disclosed are composite fabrics that can be used as crown protection plies and/or as stiffeners (9) in such tires, and the tires themselves. The cable comprises three strands twisted together in helix of pitch p2, each consisting of two metallic wires twisted together in helix of pitch p1, these wires having diameters (d1, d2), (d1?, d2?), (d1?, d2?) for the strands, respectively, such that the cable satisfies the following conditions: (i) 0.25 < d1 < 0.45 (ii) 0.25 < d2 < 0.45 (iii) 0.25 < d1? < 0.45 (iv) 0.25 < d2? < 0.45 (v) 0.25 < d1? < 0.45 (vi) 0.25 < d2? < 0.45 (vii) 2 < p1 < p2 < 10.
