<p>FIELD: multilayer cord cable for reinforcement of rubber products. SUBSTANCE: cable with unsaturated outer layer has core C0 having diameter d0 and embraced by intermediate layer C1, which is formed from M wires, with M being equal to 6 or 7, said wires having diameter d1 and being spirally wound in conjunction with one another at pitch p1. Layer C1 is enclosed in outer layer C2 formed from N wires having diameter d2 and spirally wound in conjunction with one another at pitch p2. Number N per value of from 1 to 3 units is less than maximal number Nmax of wires, which may be wound in single layer around said layer C1. Cord cable has following characteristics, mm: (i) 0.14<d0<0.28, (ii) 0.12<d1<0.25, (iii) 0.12<d2<025, (iv) for M=6: 1.10<(d0/d1)<1.40, for M=7: 1.40<(d0/d1)<1.70, (v) 5pi(d0+d1)<p1<p2<5pi(d0+2d1+d2),, (vi) wires of layers C1 and C2 are wound in the same coiling direction. EFFECT: improved quality and increased wear-resistance of cable. 21 cl, 3 dwg, 9 tbl</p> |
