Abstract (en)

[origin: WO2016066319A1] A steel cord (20, 30) has two ends and comprises steel filaments (32). At least some of the steel filaments (32) are twisted along the length of the steel cord (20, 30) - except for a local region (26, I) at at least one of the two ends - with a cord lay length Lc. The steel cord (20, 30) is additionally cold twisted in said local region (26, I) so that locally the at least some of the steel filaments (32) have a lay length that is less than 60% of the cord lay length Lc in order to avoid flare / fraying and to facilitate further processing. A corresponding method is disclosed, too.
