ABSTRACT:
A full productivity, tri-roll inverter for reversing the lead and trail edges of a sheet includes an input nip and an output nip positioned to feed sheets at a machine's process speed into and out of a chute and a reversing roll nip positioned in a predetermined position along the chute closely adjacent to but downstream of the input and output nips and adapted to open and allow a sheet to be driven into the chute by the input nip and closed to drive a sheet into the output nip. After a first sheet is captured by the output nip, the reversing roll nip is opened and a second sheet is driven into the chute by the input nip while the first sheet is simultaneously being pulled out of the chute by the output nip.
