Abstract
A reinforcing strip, and method of making same, specifically adapted for use in reinforcing plies in the belt of rubber tires. The strip comprises a number, preferably 4 to 7, of parallel wires, tightly bound together by a wrapping wire or a binder. This strip form allows to combine the advantages of steel strip, i.e. high lateral and low radial stiffness and thinner piles, with those of conventional steel cord, i.e. high tensile strength and fatigure resistance.
