    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.

    Abstract: A steel cord for reinforcing a rubber article which can improve the cut resistant property in the case of treading on an obtusely or sharply pointed projection without decreasing the strength in the axial direction of the cord and without increasing the tire weight, as well as a tire utilizing the same as a reinforcing material, are provided.The steel cord for reinforcing a rubber article has a multi-twisted structure formed by twisting a plurality of sheath strands (2) formed by twisting a plurality of wires around a core strand (2) formed by twisting a plurality of wires, and the core strand (1) and the sheath strands (2) are constituted of an at least 2-layer-twisted structure formed by twisting core wires and sheath wires respectively. In this case the relationship represented by the following formula 1.8≦[(S·cos2α)/{r·(φ1+φ2)}]×100≦4.2 is satisfied, wherein φ1: the diameter of an outermost wire of the strand (1), φ2: the diameter of an outermost wire of the strand (2), r: the center distance between the strand (1) and the strand (2), S: the cross section of the strand (2), and α: the twist angle of the strand (2).

    Abstract: A pneumatic tire has at least the outermost one of a plurality of rubber layers between a carcass and tread reinforced with a plurality of steel cords. Each of these steel cords is a single-strand steel cord with an elongation at break of not less than 4% and at least one of its component wires does not form a common circumcircle with the remaining wires. The curve circumscribing cross sections of the constituent wires of each steel cord is not a true circle. High resistance to nail penetration is assured by arranging the steel cords in such a manner that, for a large majority of steel cords, the direction of maximum offset span of the circumscribing curve is substantially coincidental with the width direction of thec outermost layer of rubber.
