Abstract
A tri-roll sheet curl control apparatus is described which includes an elastomer first roll forming a first nip with a second roll, the first roll having a compressible surface. The apparatus includes an elastomer third roll having a compressible surface which forms a second nip with the second roll surface. The second roll surface is formed of a material having a substantially noncompressible surface. The apparatus further includes a pivotable gate member that is in operating relationship with the first, second and third rolls so as to direct a sheet to either the first or the second nip so that the desired decurling orientation is achieved for the sheet by either the elastomer first roll or the elastomer third roll.
