    Abstract: PROBLEM TO BE SOLVED: To provide an open structure steel cord that has an intended elliptical shape which has a uniform ratio of the minor axis to the major axis in the longitudinal direction of the cord. SOLUTION: The steel cord is a single-layer open-structure steel cord formed of seven or more steel filaments and has a cross-section of an elliptical shape extending continuously in the longitudinal direction of the cord wherein the ratio A/B of the minor axis A to the major axis B in the elliptical shape is 0.4-0.8; the diameter d of the steel filament is 0.12-0.26 mm; and the ratio a/d of the twist pitch (a) of the cord to the diameter d of the steel filament is 30-80.

    Abstract: PROBLEM TO BE SOLVED: To provide a steel cord which is used for reinforcing rubber products, has good rubber material invasiveness, is free from the slip of a core strand group and an intermediate strand group, has a stable twist structure, is little extended with low loads, and has a three-layered structure.
    SOLUTION: The cord 10 having an L+M+N structure is produced by twisting intermediate strands 12 each having smaller pitch approximately sine wave-like curls than the pitches of curls for twisting all strands, around a core strand 11, further twisting side strands 13, and then pressing in the direction crossing the longitudinal direction of the cord. A steel cord having a 1×P structure is produced by simultaneously twisting all intermediate strands each having a smaller pitch approximately sine wave-like curls than the pitches of curls for twisting the strands with other strands, and then pressing the twisted product.
