Abstract (en)
[origin: EP0568271A1] A steel cord for the reinforcement of rubber articles has a layer twisting structure of 1 to 4 steel filaments as a core (1) and at least one sheath layer (2,3) comprised of a plurality of steel filaments arranged around the core, and a wrap steel filament (4) spirally wound around an outermost sheath layer in the same twisting direction as in this sheath layer. Further, when such steel cords are applied to a carcass ply of a radial tire, the tire durability can be considerably improved. <IMAGE>
