Reversible Paper Feed

This reversible paper feed incorporates a rotatable tube which is selectively actuated to alternatively feed sheets from a hopper to a processing station leading edge forward and face up, or leading edge trailing and face down.

Sheets 11 are fed leading edge forward face up from hopper 13 to processing station 15 over the rotatable tube 17 and feed path 19. To reverse feed, tube 17 is rotated counterclockwise a few degrees so that sheets are deflected under lip 21. The sheet then follows the inside contour of tube 17 until its leading edge hits lip 23. A paper switch at lip 23 provides a signal, causing tube 17 to rotate counterclockwise allowing the trailing edge of the sheet to trail behind until it is caught between pinch rolls 25. The pinch rolls draw the sheet out of the tube 17 trailing edge first, face down.
