A bank of upper and lower back-up rolls is in contact with the upper and lower work rolls to support the work rolls. The bank of upper and lower back-up rolls mounted to the frame via back-up housings. A second bank of upper and lower work rolls is positioned near an entry portion of the leveler. The first bank of upper and lower rolls has rolls of different diameter than the second bank of upper and lower work rolls.
