ABSTRACT:
A rolling apparatus has a frame and a first eccentric journal sleeve mounted on the frame, defining a first axis, and having axially inner and outer ends. A first shaft journaled in the sleeve has respective inner and outer ends at the first-sleeve inner and outer ends. The first-shaft outer end projects axially from the frame and carries a workpiece-deforming first roller. A rocker is displaceable transversely of the axis on the frame and carries a second eccentric journal sleeve defining a second axis generally parallel to the first axis and having axially inner and outer ends. A second shaft journaled in the second sleeve has respective inner and outer ends at the second-sleeve inner and outer ends. The second-shaft outer end also projects axially from the frame and carries a workpiece deforming second roller forming with the first roller a workpiece-receiving nip. Respective first and second drive gears engaging the respective first and second shafts between the respective ends rotate same about the respective axes. an actuator having a radially displaceable element urges the rocker radially toward the first axis and for holding the first and second axes at a predetermined spacing from each other at the outer ends.
