Hybrid rope (20) comprising a core element (22) containing high modulus fibers surrounded by at least one outer layer (24) containing wirelike metallic members (26). The core element (22) is coated (23) with a thermoplastic polyurethane or a copolyester elastomer, preferably the copolyester elastomer containing soft blocks in the range of 10 to 70 wt %. The coated material (23) on the inner core element (22) is inhibited to be pressed out in-between the wirelike members (26) of the hybrid rope (20) and the hybrid rope (20) has decreased elongation and diameter reduction after being in use.
Abstract:
Disclosed is a tire-reinforcing steel cord for a radial tire. The tire-reinforcing steel cord has a double layer structure including a first-layer core and a second-layer core provided on the surface of the first-layer core. The first-layer core has an elliptical or rectangular cross section. The tire-reinforcing steel cord can improve processability, fatigue characteristics, and rolling resistance performance of a tire, resulting in improved fuel efficiency. A radial tire using the tire-reinforcing steel cord is also disclosed.

Abstract:
Method of manufacturing a metal cord with three concentric layers (C1, C2, C3), of the type rubberized in situ, i.e. during its manufacture comprising a first, internal, layer or core (C1), around which there are wound together in a helix, at a pitch p2, in a second, intermediate, layer (C2), N wires of diameter d2, N varying from 3 to 12, around which second layer there are wound together as a helix at a pitch p3, in a third, outer, layer (C3), P wires of diameter d3, P varying from 8 to 20, the said method comprising the following steps: a sheathing step in which the core (C1) is sheathed with a rubber composition named “filling rubber”, in the uncrosslinked state; an assembling step by twisting the N wires of the second layer (C2) around the core (C1) thus sheathed in order to form, at a point named the “assembling point”, an intermediate cord named a “core strand” (C1+C2); an assembling step in which the P wires of the third layer (C3) are twisted around the core strand (C1+C2); a final twist-balancing step.
