Abstract:
A first aspect of the present invention relates to a filament (11; 12), especially for reinforcing rubber articles. Said filament (11; 12) features a contact surface (14) and an outer surface (13). In a second aspect, the invention relates to a steel cord (10) comprising two of said filaments (11, 12), the contact surfaces (14) are arranged adjacent to each other. The outer surfaces (13) are configured arcuate shaped and provide a smooth outer contour (15) of the steel cord (10). Due to said construction the largest dimension (d) of the steel cord (10) and the thickness of a rubber coating (18) may be considerably reduced. Additionally the invention relates to a method of producing a steel cord (10) and to a tyre (20) comprising a carcass ply (22) and/or at least one belt (25; 26) including said steel cords (10).
