Sheet inverting and stacking apparatus includes a rotatable inverter wheel having at least one arcuate sheet retaining slot into which a sheet may be inserted, the slot being sufficiently large in length that a substantial portion of the sheet may be inserted in the slot without the leading edge of the sheet contacting the end of the slot, a driver to incrementally rotate the wheel from a sheet load position to a sheet unload position, a driver to drive a sheet into the slot at the load position, the distance between the sheet driver and the end of the slot in the wheel being greater than the length of a sheet to be fed and a sheet stripper registration member at the unload position to strip a sheet from within the slot and register its leading edge. In a specific embodiment, the inverter comprises a fixed member having a generally cylindrical surface from the load position to the unload position and two parallel arcuate arms of larger diameter having parallel slots therein for transporting sheets from the load to the unload position and wherein the parallel arms are brought to a stop at both the load and unload positions.
