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.
