Each of the strands has a substantially same cord twisting direction and a substantially same cord twisting pitch in the steel cord, and each of the strands consists of two to five individual filaments (16, 18) twisted together. Such a multi-strand steel cord can be manufactured without having to twist the individual strands separately and beforehand.
