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.
