    Abstract: A cable (211) is provided comprising a steel cord (212) and a polymer material (215). The steel filaments (213) of the steel cord (212) are coated with an adhesive before the penetration of the polymer material (215). The cable (211) has a structural elongation less than 0.025% and an E module 4% greater than the E module of the steel cord (212). These two improvements further decrease the total elongation of the cable at certain load.

    Abstract: A cable (11) is provided comprising a steel cord (12) and a polymer material (15). The steel cord (12) has a diameter less than 2.5mm, and is coated with the polymer material (15). The cable (11) has a permanent elongation of less than 0.05% at a permanent force of 50N, after being subjected to a force of 450N. Further, a window elevator system (300) comprising such a cable (304) is provided.

    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 by the present invention is a technique which can, in a pneumatic radial tire using corrugated steel cords in the circumferential bent, improve the durability of the corrugated steel cords in order to prevent fatigue rupture thereof caused by an increase in energy input.
    The present invention is a pneumatic radial tire which has a carcass 1 as the skeleton extending in a toroidal shape between a pair of bead portions on either side of the tire, as well as a belt layer 2 and a tread layer 5 successively arranged thereonto at the outer part in the tire radial direction. The belt layer 2 comprises at least one layer of circumferential belt 3 which comprises a plurality of corrugated or zigzag-shaped steel cords extending along the tire circumferential direction, and when the steel cords are removed from the circumferential belt 3, the bending radius of curvature (R) of the steel cords is within the range from not less than 18 mm to not more than 125 mm.
