    Abstract: A tire reinforcing steel cord (1, 10) is provided which has a 1nulln structure formed by twisting together four to seven individual wires having a wire diameter of 0.20 to 0.45 mm, the steel cord being wound a plurality of times in the vicinity of opposite side edges of a belt section of a tire, wherein the steel cord has a substantially spiral or a substantially planar wavy deformation, has an elongation of 1.2% to 2.0% when applying a tensile load of 50 N in a tensile test according to JIS B 7721, and becomes substantially linear with its wavy deformation disappearing under a tensile load in the range of 50 to 250 N. When the steel cord is embedded in a tire as a zero degree belt cord, it stretches to a moderate extent so as to track the expansion of the tire in the radial direction during the vulcanization process in the molding of the tire, and since the steel cord has low stretch after the tire has been molded, it is possible to restrain expansion of the tire in the radial direction during continued high speed rotation of the tire.

    Abstract: A tire cord having core filaments preformed into a helical configuration while maintaining the core filaments in a parallel, side-by-side relationship. The core filaments are not twisted or stranded together. High tensile strength sheath filaments are also preformed into a flattened helical configuration so that the sheath filaments can be wrapped around the side-by-side core filaments such that the sheath filaments do not put such tension on the core filaments as to cause the core filaments to bunch. The core filaments are maintained in a flat, side-by-side configation so that no voids are formed and rubber can penetrate into the tire cord. The core filaments may number from three to six and the sheath filaments from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound, the oval outer bound being characterized by a major axis and a minor axis. It is desirable that the minor axis be no greater than 60% of the major axis to created the appropriate difference in the bending modulus of the tire cord in the horizontal versus the vertical direction.

    Abstract: A rubber-covered belt ply forms a belt layer. At least a majority of metal wires in the ply exist as metal wire bundles in which a plurality of metal wires of circular cross-sections and substantially equal wire diameters are aligned in parallel without being twisted together, the metal wire bundles being aligned planarly and in parallel with intervals between the metal wire bundles in a transverse direction. At least one layer, which is a cap layer in which organic fibers are covered with rubber and/or a reinforcing layer which is formed of rubber or whose main component is rubber, is disposed between the belt layer and a tread.

    Abstract: A steel cord comprising a number (between 3 and 27) of element steel wires tightly twisted at a regular pitch P between 5 and 20 mm in the same direction. Each wire has a diameter d between 0.1 and 0.4 mm. At least one of the wires includes a spiral portion having a spiral pitch P1 between 0.1P and 0.7P and a spiral diameter d1 between d+2/100 mm and d+2/10 mm. At least one other wire includes a straight portion. At any cross section of the cord, 1/4 through 2/3 of the wires is/are spiral and the other wire/s is/are straight. The stretch of the cord under a load of 5 kg is between 0.10 and 0.40%. A method of producing a steel cord comprises supplying a number of element steel wires, forming at least part of at least one of the wires to be spiral, and tightly twisting the wires. An apparatus for producing a steel cord comprises feeders supported by a frame, each feeding an element steel wire along an axis, a tension device for applying a tension to the wire from at least one of the feeders, a spiral device having pins which extend across and are spaced along an axis, so that at least one of the wires from the tension device turns alternately over and under the pins, a strand device rotatable on the axis, so that the wires are twisted to form a strand, and a take-up device to take up the strand.
