    Abstract: An object of the present invention is to provide a rubber-steel hybrid cord which makes it possible to sufficiently reduce the proportion of an adhesion promoter or sulfur while maintaining good adhesiveness, and to provide a pneumatic radial tire using the same as a reinforcement layer.To achieve this object, a rubber-steel hybrid cord of the present invention is characteristically formed by twisting a plurality of sheath filaments or sheath strands around a core in which a periphery of and space surrounded by one or a plurality of core filaments or a core strand are coated or filled with a filler rubber (A) containing an adhesion promoter, thereby forming a multilayer-twist steel cord or a multi-twist steel cord, and coating an outer surface of the multilayer-twist steel cord or the multi-twist steel cord with a coating rubber (C). Further, an amount of an adhesion promoter contained in the coating rubber (C) is equal to or more than an amount of the adhesion promoter contained in the filler rubber (A).

    Abstract: Method of manufacturing a metal cable having two layers (Ci, Ce) of construction M+N, comprising an inner layer (Ci) having M wires of diameter d1 wound together in a helix at a pitch p1, M varying from 2 to 4, and an outer layer (Ce) of N wires of diameter d2, wound together in a helix at a pitch p2 around the inner layer (Ci), the method comprising the following steps performed in line: a step of assembling the M core wires by twisting to form the inner layer (Ci) at a point of assembling; downstream of the point of assembling of the M core wires, a step of sheathing the inner layer (Ci) with a diene rubber composition called “filling rubber”, in the raw state; a step of assembling the N wires of the outer layer (Ce) by twisting around the inner layer (Ci) thus sheathed; and a step of twist balancing. Also disclosed is a device for implementing such a method.
