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.

Abstract: A method of converting scrap or other small pieces of metal into a useful, commercial product while maintaining the metal in a solid state. According to the process, the pieces are maintained together for further processing. They are impacted, while heated, to produce a metal body and thereafter subjected to continued impaction so that the pieces forming the body are welded together into a cohesive, homogeneous slab. There is also disclosure of a novel press and method of operating the press. The press is of the harmonic type. Its novel aspects include control of movement of novel platens during rotation of shafts which drive the platens and perimetral constraint of a workpiece being forged to achieve rapid impaction and self feed of a workpiece.
