摘要：
In a method of manufacturing a two-layer multistrand metal cord, N wires constituting an outer strand layer are wound in a helix around two wires constituting an inner strand layer, so as to form a strand. L>1 previously formed strands, which are incorporated as outer strands of an unsaturated outer cord layer of the cord, are wound in a helix around K>1 previously formed strands, which are incorporated as inner strands of an inner cord layer of the cord, to form a wound cord. The wound cord is overtwisted, the overtwisted cord is balanced so as to obtain zero residual torque in the overtwisted cord, and the balanced overtwisted cord is untwisted.
