Disclosed is an inverter translation device which translates the trail edge of a copy sheet in a paper handling inverter found in certain printing and copying machines having duplex capability. The device is comprised of an inverter assembly 1 which accepts copy sheets from and provides copy sheets an inversion nip comprised of input drive nip 2 and output drive nip 3. A cam roller 4 (Fig. 1) or optionally star wheel 5 (Fig. 2) provides a positive translation force or stroke to the trail edge of each copy sheet as the sheet enters and they leave the inverter assembly 1. The device employing either cam roller 4 or star wheel 5 provides a means of reliably and controlably pushing copy sheets and reduces variability in paper handling processes compared to a foam coated roll alternative.
