Official abstract text for this publication.
A steel cord ( 20 ) comprises a plurality of steel filaments ( 22, 24 ) arranged in parallel to the longitudinal axis of the steel cord ( 20 ) without twisting. The steel cord ( 20 ) further comprises a wrapping filament ( 26 ) twisted around the steel cord ( 20 ). Each of said steel filaments ( 22, 24 ) is a flat wire having flat surfaces. The steel filament ( 24 ) near the center of the steel cord ( 20 ) has a bigger width than the steel filaments ( 22 ) further away from the center of the steel cord ( 20 ) such that the cross-section of said steel cord ( 20 ) approximates an oval shape with the bending stiffness around the shorter axis of the oval shape being greater than the bending stiffness around the longer axis. In a tire, the steel cord being used as a reinforcement, the longer axis being arranged perpendicular to the radial direction of the tire.

The invention claimed is: 1. A steel cord comprising a plurality of steel filaments arranged in parallel without twisting, said steel cord further comprising a wrapping filament twisted around said steel filaments, said plurality of steel filaments being flat wires having flat surfaces, said plurality of steel filaments being in contact with each other along said flat surfaces, the lateral bending stiffness (in a horizontal plane) is greater than the radial bending stiffness (in a…
