Abstract
Methods and devices control a de-curling apparatus. A roll of material is fed through a nip formed between a first roller having a concave shape and a second roller contacting the first roller. The second roller has a convex shape mirroring the concave shape. The methods and devices automatically and continually adjust the amount of pressure applied at the nip between the first roller and the second roller as the material is unrolled from the roll into the nip.
