Leveling machine and method

An assembly for leveling a metal strip during strip movement therethrough comprising:

• a work roll for engaging and working the strip;
• a backup roll supporting the work roll against the strip;
• a cam roll supporting the backup roll against the work roll;
• a frame supporting the cam roll against the backup roll;
• and,
• an adjustment screw associated with the backup roll for selectively adjusting a relative position of the backup roll to the cam roll.

A method of flattening a strip by adjusting a leveler to avoid or compensate for position cam roll marks on intermediate rolls due to operating wear, the leveler including work rolls braced by a frame and a plurality of the intermediate rolls wherein the frame engages the intermediate rolls at spaced positions by cam rolls the method comprising the steps of:

• fixing the intermediate rolls to the frame with a guide system for adjusting a position of the intermediate rolls relative to the cam rolls by adjusting a screw position of a yoke assembly fastened to the intermediate rolls;
• in anticipation of undesired backup roll marks, adjusting the guide system to shift the spaced positions of engagement between the cam rolls and the intermediate rolls to a shifted position of engagement;
• and,
• moving the strip through the leveler.
