ABSTRACT:
A system and method for cleaning the work rolls of a multi-roll leveler. The system includes a roll cleaning drive system for driving one or both of a set of upper and lower work rolls against a cleaning pad placed therebetween. The roll cleaning drive system is disengageable with the work rolls to be driven thereby. The upper and lower work rolls are driven in opposite rotational directions so as not to eject the cleaning pad from the leveler. The rotational direction of the upper and lower work rolls may be periodically reversed to produce a scrubbing action on the work rolls.
