    Abstract: A cord with an elongated cross-section and adapted for the reinforcement of plies in a pneumatic tire, comprises a layer of steel filaments that are wound around an untwisted monofilament core, the monofilament core having a tensile strength of at least 1800 N/mm², an elongation at rupture of at least 2 per cent and a breadth-to-thickness ratio of at least 2. This structure combines the properties of flat wires with those of steel cords having substantially round cross-sections.

    Abstract: The invention relates to a strong load-handling band, such as a multi-­lift band (12), double-lift band (25) and a load-strapping band (26), its supporting part being a core made up of numerous reinforcing plastic films (11) of the same width as the band. The films (11) are laminated one on top of the other, in which case they remain parallel during the handling of the load. The bands can also be encircled with a plastic protective mantle (16) of one or several layers.

    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.
