    Abstract: The present invention relates to a high strength steel cord(1) for pneumatic tires, which is produced by the process of drawing high strength carbon steel with carbon content of 0.91.about.2.0% by weight, plating brass on the surface of the carbon steel so that it adheres to the rubber and repeating the drawing and stranding of said carbon steel. In particular, as the steel cord is composed of a filament of two strips, the steel cord according to the present invention is of a higher strength than conventional steel cord, and therefore when it is applied to a tire, the amount of steel cord and rubber topping used can be reduced, thereby resulting in a lighter weight tire, cost savings and lower fuel consumption rate.

    Abstract: A cord comprising at least a first pair and a second pair of wires (2a, 2b) of different diameter randomly disposed in transverse cross section thereof, is obtained by arranging in a nacelle (7) of a double-twisting laying machine, a twister (16) operating upstream of a preformer (15). The twister (16), rotating in a direction opposite to that of the impeller (5) and at a speed which is twice that of the impeller, neutralizes the internal torsional stresses induced in the wires (2a, 2b) by effect of the double twisting carried out upon the action of the impeller itself. Thus, a better control of the preforming operation executed on the wires (2a, 2b) disposed parallel in respectively coplanar axes is enabled. The obtained cord (1), within each laying pitch and only under a traction condition involving a load not exceeding 5 kg, has at least one right cross section in which at least one wire (2a, 2b) is spaced apart from at least one of the adjacent wires so as to facilitate the rubberizing step, by enabling access of the blend to the cross section and penetration thereof along the cord axis. The cord is preferably used as a reinforcing element for the belt structure.

    Abstract: A rubber article-reinforcing steel cord includes a core obtained by forming a single filament in a wavy shape, an inner sheath formed by arranging 5 to 6 filaments around the core, and an outer sheath formed by arranging 9 to 12 filaments around the inner sheath. The inner sheath and said outer sheath are twisted together. The diameter of each of the filaments of the inner and outer sheaths is not greater than that of the filaments of the core, 5d .ltoreq.L.ltoreq.3d and 1.2.ltoreq.H.ltoreq.d2.0d in which L and H are a wave length and a wave height of a wave shape of the waved filaments of the core, respectively, and d is a diameter of the filament of the core, and a ratio p.sub.3 /p.sub.2 between the twisting pitch p.sub.2 of the inner sheath and the twisting pitch p.sub.3 of the outer sheath is in a range of 1.4 to 2.5. A heavy duty pneumatic radial tire is also disclosed, which uses such steel cords in a belt.

    Abstract: A reinforcement cable is formed of an assembly of strands. Each strand is formed of two wires wound around each other in the same direction, with a constant pitch whose length is less than 300 mm. The two wires have linear contact with each other in the form of a helix. These helices have the same direction and the same constant pitch length. The assembly is formed of two strands of the same length of pitch and wound in opposite directions and/or it is formed of two to four strands such that the assembly has the same length of pitch and wound in the same direction as one strand and, with respect to another strand, a different length of pitch and/or wound in an opposite direction.
