Abstract
A system for decurling a sheet which is being advanced in a predetermined path within a printing machine includes a mechanism for generating a flow of room ambient air. The decurling system further includes a mechanism for directing the flow of room ambient air onto the sheet. Moreover, the decurling system includes a decurler adapted to apply mechanical force to the sheet after the flow of room ambient air has been directed onto the sheet by the directing mechanism. Finally, a mechanism is included for rotating the sheet to advance the sheet to the decurler in a direction substantially perpendicular to the direction of the predetermined path.
