ABSTRACT:
A rod or bar mill stand has two work-roll carrying mountings which are pivoted together on one side of the plane containing the roll axes and which are individually connected to synchronously driven eccentrices. The eccentric drives for the roll mountings, together with the pivotal connection, cause each of the roll axes to follow an eliptical or oval path, such that each roll approaches the pass line to reduce the work, over a part only of the path. The work rolls are driven about their own axes to induce forward movement of the work.
