Abstract: A steel cord used for reinforcing rubber product with an oval cross-section has a structure of m+n, while m is the number of core wires (26) and n is the number of the outer layer wires (22). The core wire (26) is untwisted while m is 1 or the core wires (26) are untwisted and aligned in parallel while m is between 2 and 4, and the outer layer wires (22) are twisted around said core wires (26). The core wires (26) are oval wires and the outer layer wires (22) are round wires. The wires (22, 26) in the steel cord have a carbon content not less than 0.60%.

Abstract: A steel cord (10) adapted for the reinforcement of rubber products, comprises a core strand (12) and six peripheral strands (14) concentrically surrounding the core strand (12). Each of the core and peripheral strands (12, 14) comprises a centre of two or more centre filaments (16) and two layers of filaments surrounding the centre. The core strand (12) has a diameter D1 which is greater than the diameter D2 of the peripheral strands (14). All the filaments (18, 20) of each layer have substantially the same diameter and a radially outer layer has a twist angle which is greater than a twist angle of a radially inner layer of the same strand. Each of the strands (12, 14) in the cord is composed of no more than twenty-six filaments (16, 18, 20) being twisted together.
