<p>A tri-directional inverter (100) for use in machines requiring copy sheet inversion for collated copy set output uses four rollers forming three sheet-feeding nips (105, 110, 115). All sheets enter the center nip (110) and contact a diverter gate (120) that urges them in either of two directions. The sheets are corrugated by corrugating rollers (130) as they enter a spring loaded inversion channel (150). The spring (160) and corrugation rollers (130) urge the sheets back out of the inversion channel (150) into engagement with either of the selected other nips (105, 115) formed by the four rollers for feeding back into the machine for further processing.</p> |
