ABSTRACT:
A sheet inverter and stacking apparatus has at least one sheet inverter wheel having at least one arcuate sheet retaining slot into which a sheet may be inserted. The wheel is incrementally rotated from a sheet load position to a sheet unload position and a sheet is driven in the process direction into the slot when the inverter wheel is in the load position. The sheet is removed from the slot, stacked in a stacking tray and its leading edge registered. The sheet retaining slot provides minimal resistance to sheet movement in the slot upon insertion in the slot in the process direction and provides high resistance to sheet movement in the slot in a sideways direction transverse to the process direction.
