ABSTRACT:
A composite cord for reinforcing a tire or other elastomeric article having at least one high strength, substantially inextensible yarn spirally wrapped around a core. The core at room temperature has sufficient strength and elasticity to resist and recover from tension forces on the core required during the processing of the cord and building of the tire. The core is composed of material which loses its tensile strength when subjected to temperatures of vulcanization to permit stretching out of the yarn to allow for substantial elongation of a part or all of the tire and then provide reinforcement of the elongated tire by the stretched out, high strength yarn.
