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.
Claims10
A steel cord adapted for the reinforcement of elastomers, said steel cord comprising individual steel filaments, some of said individual steel filaments being twisted individually around their longitudinal axes, some of these steel filaments having a difference in torsion saturation level in comparison with other steel filaments, the cord as a whole having substantially no residual torsions and each of the individual steel filaments having substantially no residual torsions.
