IMPROVEMENTS IN PNEUMATIC TYRES,METAL CORDS FOR MAKING INTO PLIES FOR USE IN PNEUMATIC TYRES AND PLIES OF SUCH METAL CORDS

摘要

Metal cables of improved fatigue strength, which are particularly suitable for use in an oblique folded ply of metal cables for tire tread reinforcement, comprise a visible outer layer of strands with each strand being formed of at least two elementary wires, the pitch of the strands being less than the pitch of the elementary wires, these two pitches being of the same direction (S or Z).
