    摘要: A process and machine for making a cord in a structure of one or more layers of filaments, all twisted with a same twist pitch p around a core in which the filaments are not twisted around each other with that same twist pitch p. The cord is made in one continous process in which the core filaments are bundled in a twister, then the layer filaments are joined in parallel to the core bundle on exit from the twister, and the whole is then twisted in a double-twist bunching machine.

    摘要: 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 plies, with those of conventional steel cord, i.e. high tensile strength and fatigue resistance.
