    Abstract: A reinforcing steel cord for rubber products, such as steel belted radial tires or conveyor belts, is disclosed. This steel cord is improved in rubber penetration and ageing adhesive force relative to the rubber material. The steel cord is formed by twisting a plurality of brass coated external element wires around a flat and spirally twisted core, with the twisted direction of the core being the same as or opposite to that of the resulting steel cord. In the steel cord, the pitch of the twisted core is set to allow the core to be twisted 0.2 to 2 times within the pitch of the cord, thus preferably forming sufficient interspaces between the core and the external wires in addition to the interspaces between the external wires. Since the rubber material is completely filled in the steel cord due to such interspaces, the steel cord is remarkably improved in buckling fatigue resistance, rubber penetration, air permeability, rubber adhesive force, ageing adhesive force relative to rubber, protection of brass coated surfaces of wires, and workability during a process of producing rubber products. The steel cords of this invention are most preferably used as a reinforcing material for steel belted radial tires.

    Abstract: A steel cord (10) adapted for the reinforcement of elastomers, comprises individual steel filaments (12, 14). Some of these steel filaments (12) have a difference in torsion saturation level in comparison with other steel filaments (14). All of the individual steel filaments have a predetermined number of residual torsions and are preferably free of residual torsions. Such a steel cord is manufactured by making use of two false twisters.
