Abstract (en)
[origin: EP0627521A1] A steel cord (12) having steel filaments (2) twisted so as to have a final twist pitch, is subjected to a step (i) of plastically deforming the steel filaments (2) by overtwisting the steel cord (12) until a twist pitch which is smaller than the final twist pitch, a step (ii) of untwisting the steel cord (12) until the final twist pitch, a step (iii) of further untwisting the steel cord (12) until a twist pitch which is greater than the final twist pitch, a step (iv) of twisting the steel cord (12) again to its final twist pitch. Steps (i) and (ii) are done under a first tension and steps (iii) and (iv) are done under a second tension, the second tension is lower than half the first tension. <IMAGE>
