Four Roller Precision Steel Sheet Leveler

Roll diameter decides what a leveler can do, and that's the first thing to argue about when you're specifying one. Small rolls bend sheet tightly and suit thin material. Big rolls bend gently and handle thick plate without marking it. Four large rolls is the compromise that fits shops cutting 2mm to 12mm from coil.   The physics is easy to state. The sheet has to be bent past yield in both directions, with decreasing curvature, so the residual stress pattern ends up balanced. If the first bend is too shallow, the sheet stays bowed. If the last bend is too deep, it curls the other way. Setting gap and tilt correctly is the entire skill, which is why the panel stores recipes instead of asking the operator to remember numbers. A four roller leveler at 1300mm wide, 0.5mm to 12mm, is the workhorse size. It sits between the uncoiler and the shear on a cut to length line, or between the slitting head and the recoiler if you're slitting. Either way it takes coil set out before the material g…
