A tri-roll inverter for use in machines requiring copy sheet inversion for collated copy set output includes input and output nips. All sheets entering the input nip of the inverter are corrugated by a corrugation system as they enter a spring loaded inversion channel. The corrugation system includes an idler roll, a steel driver roll, and two plastic driver rolls on opposite sides of the steel driver roll. The spring and corrugation system urge the sheets back out of the inversion channel into engagement with the output nip for feeding back into a machine for further processing. The plastic rolls enable each sheet to reach zero velocity quickly and invert at a fast rate without stalling or jamming.
