    Abstract: A steel cord is disclosed for use in reinforcing rubber products, especially automobile tires. In order to provide desirable rubber penetrability and break-resistance, three to six material wires are intertwisted into a steel cord having an elliptically shaped cross section having a ratio of its major diameter to its minor diameter of between 1.1 and 2.2. The cord is formed such that its material wires substantially contact each other near the ends of the major axis of the ellipse and are separated from each other near the end of the minor axis. The cord of the invention is normally formed such that a ratio the twist pitch to the material wire diameter is in the range of 30-80. However, if a high elongation of more than 5% is necessary, such can be imparted by intertwisting material wires such that the ratio of the twist pitch to the material wire diameter is in the range of 10-28.

    Abstract: Metal cord, for reinforcing articles of an elastomeric material, such as tires, conveyor belts and so on of the single strand type, in particular made up of a plurality of 3, 4 or 5 wires, wherein the said wires are twisted together loosely, so as to result as being spaced apart from each other but in such a way that the ratio between the diameter of the circumference circumscribing the swollen cord and the diameter of the circumference circumscribing the corresponding compact cord, is comprised between 1.06 and 1.20. A thus realized cord consents for an optimum penetration of the elastomeric filler material but at the same time a tensile behavior, and in particular an elongation in the field of low values of loads applied, which does not differ in any appreciable way from that of the corresponding compact cord.

    Abstract: A torque coil (two-layer coil structure) of the disclosed embodiments includes an inner coil formed by spirally winding metal wire, and an outer coil arranged to be in close contact with the outer periphery of the inner coil and formed by spirally winding metal wire. A winding direction of the inner coil and a winding direction of the outer coil are opposite from each other, and when the torque coil is twisted in the circumferential direction in which the diameter of the inner coil is increased, a change amount of the diameter of the outer coil is larger than a change amount of the diameter of the inner coil. The two-layer coil structure has high twisting rigidity, thus suppressing the occurrence of kinks due to rotational resistance.

    Abstract: A metal cord includes at least one preformed elementary metal wire. The metal cord has an elongation at break, measured on the bare cord, higher than or equal to 3%, preferably 4% to 6%; an elongation at break, measured on the rubberized and vulcanized cord, which differs in an amount not higher than or equal to 15%, preferably 2% to 10% with respect to the elongation at break measured on the bare cord; a part load elongation, measured on the bare cord, higher than or equal to 0.4%, preferably 0.5% to 1.5%; a part load elongation, measured on the rubberized and vulcanized cord, which differs in an amount not higher than or equal to 15%, preferably 0.5% to 10%, with respect to the part load elongation measured on the bare cord.
