    Abstract: Process for producing a steel cord for pneumatic tires comprising a bunch of wires, the core of which consists of wire filaments 10 arranged bunched juxtaposed in parallel. Preferably at least three wire filaments 10, 20 are provided, at least two wire filaments located juxtaposed in parallel being spirally shaped as core filaments 10 forming a core 60 and at least one wire filament spirally surrounding the two core filaments 10 as a sheathing wire 20. Spirally shaping the wire filaments 10 is achieved in accordance with the invention by false twisters 40. Due to this spiral shaping of the wire filaments 10 migration of the filaments from the core composite is avoided more particularly. The residual torsional stresses of the core filaments among each other and in conjunction with the restoring forces of the sheathing wire are advantageously cancelled. In addition, the steel cord features to advantage a flattened, more particularly, oval shape.

    Abstract: An oval or elliptical shaped overhead conductor that is twisted along its length to provide a continuously varying profile to the wind. A single core is comprised of a circular center wire wrapped by circular wires and the core is surrounded or encased by one or more layers of wire strands, including strands of different size from that of the core wires. Each layer is helically wound in a direction opposite to the underlying layers. The surrounding strands may be circular, with the strand sizes symmetrically arranged to result in a substantially oval or elliptical cross-section. Alternatively, the strands may be shaped into symmetrically arranged non-circular arcuate cross-sections, which when wound together result in an oval or elliptical conductor cross-section. The core strands are each circular or round wires having the same diameter, with the result that the core is easy and inexpensive to manufacture. The conductor is capable of manufacture in one step by winding the core and outer layers at the same time. A helical winding along the length of the conductor results in altering the profile that is presented to the wind, thereby substantially cancelling wind-induced forces in adjacent conductor segments or regions, thus damping conductor vibrations.

    Abstract: A steel cord is disclosed for use in reinforcing rubber products, especially automobile tires. In order to provide desirable rubber penetrability and break-resistance, three to six material wires are intertwisted into a steel cord having an elliptically shaped cross section having a ratio of its major diameter to its minor diameter of between 1.1 and 2.2. The cord is formed such that its material wires substantially contact each other near the ends of the major axis of the ellipse and are separated from each other near the end of the minor axis. The cord of the invention is normally formed such that a ratio the twist pitch to the material wire diameter is in the range of 30-80. However, if a high elongation of more than 5% is necessary, such can be imparted by intertwisting material wires such that the ratio of the twist pitch to the material wire diameter is in the range of 10-28.
