Abstract
A machine for drawing a plurality of metal wires including alternate odd-numbered wires and even-numbered wires, in which a plurality of drawing drums are rotatable in two parallel rows, each individual drum having a plurality of tracks at least equal to the number of wires to be drawn, the wire moving along a path which changes direction by extending successively from a drum in one row to a drum in the other row. A group of dies is arranged between each successive pair of drums, one die in each group serving for the passage of one of the wires. Two final drums are provided, and two sets of dies are arranged at different levels between the penultimate drums and the two final drums. One set and one final drum serves for the odd-numbered wires and the other set and the other final drum for the even-numbered wires.
