Abstract (en)
A cord with an elongated cross-section and adapted for the reinforcement of plies in a pneumatic tire, comprises a layer of steel filaments that are wound around an untwisted monofilament core, the monofilament core having a tensile strength of at least 1800 N/mm<2>, an elongation at rupture of at least 2 per cent and a breadth-to-thickness ratio of at least 2. This structure combines the properties of flat wires with those of steel cords having substantially round cross-sections.
