    Abstract: A high elongation compact helical steel cord with a high degree of elongation at break of not less than 5% has a (1.times.n) structure comprising three or more base wires which are helically preformed at a predetermined pitch and which are twisted in the same direction and at the same pitch so that the ratio P/D of the cord diameter D to the twisting pitch P is in the range of 8-15 with the base wire preforming pitch being shorter than the cord twisting pitch. The finished cord has a helical composite structure with its elongation under a load of 35 kgf/mm.sup.2 being 0.71%-1.00% and that under a load of 70 kgf/mm.sup.2 being 1.18%-1.57%. A radial tire is reinforced with the steel cord preferably as a steel belt cord. An apparatus for making the steel cord is provided with revolving preformers on the wire introducing portion of a bunching machine such that the bunching machine is rotated in a direction reverse to the rotational direction of the revolving preformers.

    Abstract: A steel tire cord is composed of three to five strands twisted closely with minimum gaps between the strands. The steel tire cord is easy to handle in embedding the same in rubber to form a tire, free from corrosion and highly durable. A tire incorporates the steel tire cords which are bonded firmly to rubber in a belt layer. Tires thus fabricated are uniform in quality and highly durable. The steel tire cord is composed of three to five twisted strands arranged in a construction reducing the sectional area of spaces in the steel tire cord to a minimum. The core strands twist in helices around imaginary cylinders having axes aligned with the axis of the steel tire cord. The outside strands twist in helices around imaginary cylinders having axes aligned with the axis of the steel tire cord and having diameters greater than those of the imaginary cylinders around which the core strands twist. At least one of the strands among the component strands of the steel tire cord is crimped to form bends therein. The core strands and the outside strands are arranged closely in a triangular sectional construction with gaps between the crimped strand and the adjacent strands. In the tire incorporating the steel tire cords, the outer enveloping surface of the steel tire cord, and inner enveloping surfaces defining the spaces having a triangular cross section are covered closely with rubber, so that the steel tire cords and the rubber are bonded firmly.

    Abstract: A locking cable which is constructed of a plurality of separate strands with each strand containing a plurality of separate wires, each wire being between 0.005 and 0.012 of an inch in diameter. One side of the cable along its entire longitudinal length is stretched so that the material along that side is caused to exceed its yield point and be permanently deformed. As a result, the cable assumes a natural helical coiled configuration. A plastic cover may be applied to the cable in a close fitting relationship to help prevent the cable from becoming untwisted. The method of making the helical coiled cable comprises preforming and twisting of a plurality of separate wires together in a clockwise direction to form a strand, preforming and twisting a plurality of separate strands together in a counterclockwise direction to form the cable, and stretching one side of the cable along its entire length. An apparatus to perform the method of this invention comprises a pair of roller assemblies through which the cable is conducted with the cable being passed about a pin with an angular displacement exceeding 190*. The cable is passed through the apparatus in an extremely taut manner which causes one side of the cable to be permanently deformed.
