Abstract (en)
[origin: WO0149926A1] The invention relates to a multilayer cable with an unsaturated outer layer for use as an element for reinforcing the frame of a tire carcass, comprising a core which has a diameter d0 and which is surrounded by an intermediate layer (C1). Said intermediate layer consists of 4 or 5 wires (M = 4 or 5) which have a diameter d1 and which are wound together in a spiral according to a lay p1. Said layer (C1) is itself surrounded by an outer layer (C2) consisting of N wires which have a diameter d2 and which are wound together in a spiral according to a lay p2, N being less than the maximum number Nmax of wires that can be wound around the layer (C1) in a spiral by 1 to 3. The cable has the following characteristics (d0, d1, d2, p1 and p2 in mm): (i) 0,08 < d0 < 0,28; (ii) 0,15 < d1 < 0,28; (iii) 0,12 < d2 <0,25; (iv) for M = 4: 0,40 < (d0/d1) < 0,80; for M = 5: 0,70 < (d0/d1) < 1,10; (v) 4,8 pi (d0 + d1) < p1 < p2 < 5,6 pi (d0 + 2d1 + d2); (vi) the wires of layers (C1) and (C2) being wound in the same direction of twist. The invention also relates to plastic and/or rubber items or semi-finished products which are reinforced by a multilayer cable of this type, especially tires for industrial vehicles, especially heavy vehicles tires and their carcass belts.
