摘要： 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.

摘要： A steel cord for reinforcing automobile tires is composed by intertwisting at least one material wire having small spiral-like curls and 1 to 5 straight material wires. This restricts the ratio of fracture elongation of the two kinds of material wires as well as the elongation percent of the cord at 5 kg loading and improves the stability of twist, the fatigue resistance, the penetrability of a rubber compound and the handling workability.
