Abstract
Abstract A metallic cable for reinforcing elastomeric articles comprises two strands of two filaments twisted together and having a cable lay length. The filaments of each strand are twisted together and the strands have strand lay lengths that are equal to one another but different from the cable lay length. The direction of twist of the strands may be either the same as, or opposite to the direction of twist of the cable.
