    Abstract: PURPOSE: A reinforcing steel cord for rubber products such as steel belted radial tires or conveyor belts having improved rubber penetration and ageing adhesive force to rubber material by improving the mechanism of a twisted core to minimize the continuous contact of the core and external wires and forming sufficient interspaces between the core and the external wires is provided, which is most preferably used as a reinforcing material for steel belted radial tires. CONSTITUTION: In the steel cord, the pitch of the twisted core is set to allow the core to be twisted 0.2 to 2 times within the pitch of the cord, thus preferably forming sufficient interspaces between the core and the external wires in addition to the interspaces between the external wires. Since the rubber material is completely filled in the steel cord due to such interspaces, the steel cord is remarkably improved in buckling fatigue resistance, rubber penetration, air permeability, rubber adhesive force, ageing adhesive force relative to rubber, protection of brass coated surfaces of wires, and workability during a process of producing rubber products.

    Abstract: PURPOSE: A process of steel cord of rubber reinforcing serves rubber adhesive power apparatus of steel cord and durability increase of rubber product by gaining steel cord of effective structure to remove central cavity of rafter(1x3), reduces manufacturing time, simplifies manufacturing device, increases energy efficiency by composing to rotate device itself using rotary driving power of stranded-wire apparatus without additional power. CONSTITUTION: The process of steel cord(20) of rubber reinforcing comprises rolling process to roll core wire(20a) of flat shape section; twisting process by screwing core wire(20a) of flat shape section to center line; stranded-wire process to be twisted by combining core wire(20a) and outer stainless wire(20b) at least one among twist direction and twist pitch of core wire(20a) by being different from twist direction and twist pitch of cord; twist direction of core wire(20a) and twist direction of cord is opposed; rolling process for core wire(20a) and twisting process by screwing core wire(20a) to be executed simultaneously.

    Abstract: Provided are a rubber article reinforcing steel wire that is superior in bending fatigue properties to the related art and has a flat cross-sectional shape, and a rubber article using the wire. In a rubber article reinforcing steel wire 10, a major diameter and a minor diameter are substantially perpendicular to each other. Assuming that the major diameter is W, the minor diameter is T, a straight line that passes through a center of the major diameter in a width direction and is parallel to a minor diameter direction is L1, a straight line that passes through a center of the minor diameter in a width direction and is parallel to a major diameter direction is L2, an intersection point of the L1 and the L2 is a center point C, a region within a half of a distance from the center point C to a surface is a central region Rc, and a region outside the central region Rc is a surface layer region Rs, a Vickers hardness Hvc of the central region Rc is more than a Vickers hardness Hvs of the surface layer region Rs; and assuming that a Vickers hardness on the L1 in the surface layer region Rs is Hv1, and a Vickers hardness on the L2 in the surface layer region Rs is Hv2, relationships represented by Hvc - Hv1 ‰¤ 150, Hvc - Hv2 ‰¤ 150, Hv1/Hvc × 100 ‰¥ 85.11, and Hv2/Hvc × 100 ‰¥ 79.84 are satisfied.
