Abstract (en)
The present invention relates to a steel cord (10) especially for reinforcing rubber articles. The steel cord (10) comprises at least one bundle (11) of several helically shaped filaments (12) and at least one single filament (13). In accordance with the invention the flexural strength of said at least one bundle (11) amounts to at least 50 percent or at most 150 percent of the flexural strength of said at least one single filament (13). Preferably, the flexural strength of said bundle is between 50 and 150 percent of the flexural strength of the at least one single filament. When twisting the bundle (11) with the single filament (13) the desired helical shape of the filaments (12) of the bundle (11) is achieved automatically. It is no longer necessary to pre-shape said filaments (12) so that production of the steel cord (10) is simplified. <IMAGE>
