Abstract: A multi-layer twisted strand or cable (1) comprising one central elongate element (11) surrounded by three layers of elongate elements, namely an inner layer, a middle layer and an outer layer.
Said elongate elements are wires or strands of twisted wires.
The surround elongate elements have several different sizes of area of transversal cross section thereof. The middle layer comprises elongate elements (12,14) of different size of area within the middle layer and the sizes of area of the elongate elements between the layers are different. The outer surround elongate elements (15) having the largest size of area. The outer surround elongate elements have a smoothened outer surface (152), so that the twisted strand or cable (1) has a smooth and satiny outer surface (152).
All surround elongate elements (13,12,14,15) having the same lay direction and the same pitch.
Elongation when stretch force is exerted on the twisted strand or cable and friction and abrasion caused by pulling the twisted strand or cable is reduced.

Abstract: Provided are a steel cord for reinforcing rubber whose fatigue resistance is increased more than ever to enable achieving high durability that was not conventionally realized, and a pneumatic radial tire including the steel cord as a reinforcement member. In a steel cord for reinforcing rubber having a double-twist structure that includes a plurality of strands twisted together in the same direction with the same pitch and including a central structure and at least one outer layer, the central structure is composed of at least two strands being twisted around each other and each being composed of at least seven filaments being twisted together.; In a steel cord for reinforcing rubber including at least three core strands being twisted together and at least six sheath strands being twisted together around the core strands, the core strands and the sheath strands are twisted in the same direction.

Abstract: Method of manufacturing a metal cord with three concentric layers (C1, C2, C3), that is rubberized in situ, of construction M+N+P, comprising an internal first layer (C1) made up of M filaments of diameter d
1 , M varying from 1 to 4, around which there are wrapped together in a helix at a pitch p2, as an intermediate second layer (C2), N filaments of diameter d
2 , N varying from 3 to 12, around which there are wrapped together in a helix at a pitch p
3 , as an outer third layer (C3), P filaments of diameter d
3 , P varying from 8 to 20, said method comprising the following steps performed in line: - a step of assembling, by twisting, the N filaments around the first layer (C1), in order to form at a point known as the "assembly point" an intermediate cord known as a "cored strand" of construction M+N; - downstream of the assembly point, a step of jacketing the cored strand M+N with a rubber compound known as "filling rubber", in the non-crosslinked state; - a step of assembling the P filaments of the first layer (C3) by twisting around the cored strand thus jacketed; - a final torsion equalizing step. Device for implementing such a method.
