    Abstract: A compact single-strand cord consisting of at least nine single wires of the same diameter twisted together in the same direction and with the same pitch, characterized in that, in cross-section, the cord has the shape of a compact stack of polygonal, preferably hexagonal, contour. The cord can be used for reinforcing rubber articles or elastomeric articles, in particular for reinforcing tires.The method of manufacture of the cord includes unwinding the wires from coils each consisting of a single wire. The wires are delivered by positive slip-drive rollers to a means for regrouping and a strand-laying means. The wires are assembled in a grid and die and twisted by an assembling twister. The wires are then guided through a double twist path loop, overtwisted, straightened and collected on a capstan.The machine for performing the process includes an unwinding means in the form of a plurality of feed bobbins, a positive slip-drive roller system, means for regrouping the advanced wires including a grid and a die, a revolving assembling twister and a spindle means including a loop and stationary cradle carrying an overtwisted, straightener and capstan for collecting the cord.

    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.
