    Abstract: A steel cord characterised by a zigzag filament which is zigzagged two dimensionally or in a plane by a zigzag pitch length (Pw) and a zigzag wave height (h) and made up of straight segments each extending between zigzag peak points, each of the zigzag pitch lengths (Pw) and zigzag wave heights (h) being ccnstant along the longitudinal direction thereof and either a second zigzag filament of the same type but having a different pitch length (Pw) or a straight filament such that the cord has an open construction so that rubber can penetrate it.
    The cord may be a single bunch or a twisting together of two or more bunches each comprising zigzag filaments. The cord may have zigzag filaments of at least two different zigzag pitch lengths.
    In each of tnese constructions the result is to give an open cord construction and the invention also includes a tyre incorporating such cord in the carcass breaker or the like.

    Abstract: A steel cord (114) for the reinforcement of rubber products comprises strength elements (100, 132) and has length, a longitudinal central axis (112) and a cord pitch. Each of the elements (100) has a projection on a plane YZ perpendicular to the longitudinal central axis (112). At least one of these projections takes the form of a curve with a radius of curvature which alternates between a maximum and minimum. The curve further has a center of curvature. The radius of curvature and the center of curvature lie inside the curve so that a convex curve is obtained. The cord (114) is further characterized by one or both of the following features: (i) the distance between two minimum radii of curvature of said curve measured along the longitudinal central axis (112) is different from half the cord pitch; or (ii) if all of said elements (100) provide a convex curve, at least one of said convex curves substantially differs from another convex curve. The steel cord (114) allows full rubber penetration despite low values of cord diameter and part load elongation (PLE).

    Abstract: Provided is a pneumatic radial tire in which a fatigue rapture of the steel cord is prevented and durability of a circumferential belt is improved.
    In a pneumatic radial tire which has as a skeleton a carcass extending in a toroidal shape between a left-and-right pair of bead portions, and has a belt layer and tread layer successively arranged onto the carcass at the outer part in the tire radial direction,
    the belt layer comprises at least one circumferential belt which consists of a plurality of corrugated or zigzag shaped steel cords extending along the tire circumferential direction, and
    at least the relations represented by the following expressions:
    -0.5 ≤ L1/ L2 ≤ 0.5,
    L2 ≤ 0

    (where, in the case where the residual stress is a tensile stress, the stress is a + value while, in the case where the residual stress is a compressive stress, the stress is a - value) are satisfied, when the steel cords of the circumferential belt are taken out, at the inside and the outside of bent portions of the steel cords which are taken out, letting the residual stress at the inside of bent portions of the filament of a sheath portion be L1 and the residual stress at the outside of bent portions of the filament of the sheath portion be L2.
