Eccentric-journal mount for rolling-frame support shafts

A rolling apparatus comprising:

• a frame;
• 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 and having respective inner and outer ends at the first-sleeve inner and outer ends, the first-shaft outer end projecting axially from the frame;
• a workpiece-deforming first roller on the first shaft axially outward of the first-shaft outer end;
• a rocker displaceable transversely of the axis on the frame;
• a second eccentric journal sleeve mounted on the rocker, 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 and having respective inner and outer ends at the second-sleeve inner and outer ends, the second-shaft outer end projecting axially from the frame;
• a workpiece deforming second roller on the second shaft axially outward of the second-shaft outer end and forming with the first roller a workpiece-receiving nips the shaft outer ends lying axially between the respective rollers and the respective inner ends;
• means including respective first and second drive gears engaging the respective first and second shafts between the respective ends for rotating same about the respective axes;
• and
• means including an actuator having a radially displaceable element for urging the rocker radially toward the first axis and for holding the first axis at a predetermined spacing from the second axis at the outer ends.
