This article describes a relatively simple apparatus for aligning cut sheets during entry to a counterrotating platen. It is important to have the sheet aligned relative to the printing platen of a typewriter or the like. Current designs use other methods, such as mechanical gates, cone-aligning rollers and closely toleranced feed rollers. Refer now to the figure. A D-shaped, high friction separator roller 1 is driven off platen 2 through a gear train assembly including a driving gear 3, idlers 4 and 5 and driven gear 6. Counterclockwise rotation of platen 2 drives roller 1 clockwise for separating and feeding the topmost sheet 7 from a stack of such sheets 8. When sheet 7 reaches counterrotating platen 2 and its backup roller 9, the sheet is aligned and continually rejected.
