Abstract (en)
Steel cord for the reinforcement of elastomer material, such as rubber, and comprising at least two strands. Each strand has a structure comprising two wire bundles (1, 2) twisted around each other to form two helicoids of same diameter and pitch. In the first bundle (1) the wires run in parallel, or nearly in parallel, and in the second bundle (2) the wires are twisted with a pitch (2) in the same sense and of the same valas the pitch (2) of said helicoids. A larger stiffness is obtained without remarkably increasing the cord diameter.
