ABSTRACT:
A multi-stage wire drawing machine having at least one drum formed with a plurality of sheaves over which the wire is sequentially pulled. The sheaves are disposed about a hollow sleeve in which is rotatably mounted a shaft connected at one end to a drive and at its other end to the farthermost sheave. The sheaves are interconnected by suitable gearing with each other and with the sleeve. The gearing is so adjusted that the peripheral speed of the individual sheaves increases in the direction of the passage of the wire, corresponding to the differential necessary to obtain only the least possible extension of the wire.
