Abstract: In order that spaces, including a space in the central portion, inside a steel cord used as a reinforcement by being embedded in a tire or the like are filled with an uncured rubber, the uncured rubber is coated on plural steel filaments 115 which are then stranded in case of a single layer steel cord, the uncured rubber is coated on all of plural core filaments 329 which are then stranded along with outer layer filaments 330 in the same direction at the same pitch in case of a 2-layer steel cord of 1 stranding process, and the uncured rubber is coated on all or 2 to 4 core filaments 218 or on at least one of 3 or 4 steel filaments 408, 408null to form a core strand and outer layer filaments 410, 410null are stranded therearound in case of 2-layer steel cord of 2 stranding process. Consequently, it is possible to exhibit satisfactory corrosion resistance and satisfactory fatigue resistance as a steel cord, shorten a curing time in tire component assembling or the like to attain energy saving and prolong the life of a steel cord itself and the life of a tire or the like using the same as a reinforcement. Further, production can be performed at low cost.

Abstract: A reinforcement assembly to be impregnated with a plastic or rubber material for reinforcing an article, such as a pneumatic tire, the assembly having three layers of cords: a core layer, an intermediate layer and an outer layer. The intermediate layer and the outer layer have the same direction of winding and the same pitch. When the core layer is wound in the same direction as the intermediate layer, the pitches of these layers differ in such a manner that the ratio between the difference in the values of these two pitches and the larger value of these two pitches is at least equal to 0.30. In the intermediate layer the axis of each cord is arranged along a helix such that the ratio between the radius of curvature of said helix and the diameter of said cord is less than 75.

Abstract: A steel cord, for use in the reinforcement of resilient articles such as rubber tires, comprises a central bundle of wires surrounded by a circumferential layer of helicoidally twisted wires. In the central bundle, one can distinguish a core and a surrounding layer, the latter having the same twist pitch as the circumferential layer. In order to reduce wire migration, the wires of the central bundle show a limited number of relative position changes, between 2 and 300 per 30 cm cord length.
