Rolling head support assembly for a rolling mill

Abstract

In a rolling mill having a perforating head supported on a bar which is rotatable and longitudinally displaceable, the bar is supported on a carriage by way of a gripper fixed to the carriage and engaging a recess in the bar with sufficient radial play to allow rotation of the bar. The recess also affords axial clearance so that the rolling reaction on the perforating head displaces the rear end of the bar into abutment with a planar end contact face of a rotating bearing. The abutment of the end of the bar against the contact face allows the bar to be ejected laterally without previous axial disengagement of the bar from the bearing.
