The invention relates to a steel cord, specially to reinforce rubber or synthetic material articles, and a method for its production. The steel cord consists of a strand (10) having at least two individual filaments (20). The individual filaments (20) are winding each other in spiral. According to the invention disclosed, the strand (10) has also a spiral shape. The method disclosed for producing said steel cord foresees that firstly at least two strands (10a) having at least two individual filaments are formed, in which the individual filaments are wound together in spiral. The strands (10a) are pulled from spools (30) and wounded into a rope using a perforated disk (40). The rope is twisted in a false twisting machine (50) and given a plastic shape. Next, the twisted and plastic shaped rope is unwound when it comes out of the false twisting machine (50). The resulting spiral-shaped strands (10b) are then wound on winding spools (60). |
