A rod or bar mill stand intended as the first stand of a continuous rod or bar mill has work rolls carried by rocking mountings which are driven to cause each roll to follow an elliptical path. In each cycle of operation, the work rolls thus roll over and reduce the work before losing contact with the work and returning to their starting positions. The work rolls are additionally driven about their own axes at a peripheral speed so chosen that the work is urged in the feed direction.
