    Abstract: A steel cord having a three-layer twisted construction consisting of an innermost layer, an intermediate layer, an outermost layer, and a spiral warp and being capable of achieving an improvement in the adhesion force to rubber while reducing the number of processing steps used. In the steel cord, the innermost layer consists of 3 filaments twisted in one of left or right twist directions while having a twist pitch length of 5 to 18 mm; the intermediate layer consists of 8 filaments twisted in the same twist direction as that of the innermost layer while having a twist pitch length of 5 to 18 mm, namely, the same twist pitch length as that of the innermost layer; the outermost layer consists of 13 filaments twisted in a left or right twist direction opposite to those of the innermost and intermediate layers while having a twist pitch length of 10 to 25 mm equal to or more than those of the innermost and intermediate layers; and the spiral wrap consists of a single filament adapted to be wrapped around the outermost layer, thereby preventing the steel cord from being unwound, the filament being twisted in a twisted direction opposite to that of the outermost layer while having a twist pitch length of 3 to 10 mm. Gaps are formed among the filaments of the intermediate and outermost layers. The gaps allow rubber to penetrate easily into the steel cord therethrough.

    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.
