Abstract

A steel cord for the reinforcement of resilient articles comprises a bundle of four wires twisted together with the same pitch, a first pair 1, 2 of said wires having a substantially similar diameter, a second pair 3, 4 of said wires each having a diameter not greater than the average diameter of the first pair 1, 2, a wire of one pair being adjacent a wire of the other pair along the circumference of the bundle, and in a stretched condition of the cord, the wires of the first pair 1, 2 are tightly twisted together so as to touch along the axis 5 while each wire of the second pair 3, 4 is at a spacing d from the circumferentially adjacent wires of the first pair.
