ABSTRACT:
An inverter for reversing the direction of movement of sheets fed to it even at high speed comprises a guide member onto and along which a sheet is fed and having an end edge portion spaced a small distance from a bend-over guide that lies across and at an acute angle to the path of the leading edge of the sheet and deflects the leading edge so that a leading portion of the sheet is bent over the end edge portion to retard the sheet movement. The sheet then is in a position to be delivered by movement in the reverse direction. The bend-over guide typically is disposed at a distance of 3 to 10 mm from the end edge portion and at an acute angle of 60.degree. to 85.degree. to the adjacent surface of the guide member. Preferably, the guide member presents a concavely bowed sheet guiding surface having angled recesses extending across it.
