    Abstract: A (1 x n)-structure tire reinforcing steel cord which is installed by being wound at opposite side edges of the belt portion of the tire, and formed by twisting 4 to 7 strands each having a wire size of 0.20-0.45 mm, the cord having a spiral/planar waveform permanency, an elongation factor being 1.2-2.0% under a tensile load of 50 N in a tensile test based on JIS B 7721, a tensile load ranging from 50 to 250 N when the cord is linearized. The cord elongates properly by following up the expansion of the tire at tire building, and, after built, has a small elongation characteristic to thereby restrict a radial expansion caused by the high-speed continuous rotation of the tire.

    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).
