ABSTRACT:
A steel cord for reinforcing rubber. It is made of three steel filaments all having different diameters from one another. The small-diameter and medium-diameter ones of the three filaments have internal stresses adapted to be released when the cord is cut at both ends thereof. Owing to these stresses, the diameter of the cord is adapted to increase after it is cut at both ends. At the same time, the medium-diameter and small-diameter filaments retract inwardly from the ends of the large-diameter and medium-diameter ones, respectively.
