1. A shuttling nip set sheet inverter for use in connection with a digital printing system and a media sheet moving along a process path in a process direction, the shuttling nip set sheet inverter comprising:
a shuttle nip having a first shuttle nip roller and a second shuttle nip roller, the first and second shuttle nip rollers being adapted for selective rotation in a forward direction and in a reverse direction, the first and second shuttle nip rollers being mounted for mutual revolving orbit about an orbital axis, the first and second shuttle nip rollers being mounted for mutual generally translational movement in the process direction from a starting position to an ending position; a main nip spaced apart from the shuttle nip a predetermined distance in the process direction; an inversion nip adjacent the main nip; a diverter gate extending between opposite first and second ends, the diverter gate being adapted for movement from an inversion position with the first end adjacent the shuttle nip and the second end adjacent the inversion nip, to a storage position away from the process path; so that in duplex operation, the media sheet lead edge will pass through the shuttle nip, the shuttle nip will revolve orbitally and translate downstream, and the trail edge will become the lead edge, inverting the media sheet. |
