Japanese Patent JP3506279
Kind Code:
B2
Abstract:
PURPOSE: To obtain a steel core with multiple-twisted structure excellent in cord strength and suitable as a reinforcing material for pneumatic tires, by entwining plural strands of ply-twisted structure.
CONSTITUTION: This steel cord with multiple-twisted structure for reinforcing rubber products is obtained by entwining seven strands each having ply-twisted structure of two or more plies composed of three core filaments each of which has 0.15-0.40mm of diameter and nine sheath filaments each of which has 0.15-0.40mm of diameter, with the twist direction of each of the outermost layer sheath filaments 4 same as that of each of the sheath strands 2 and the structure of the six sheath strands identical with each other.
