Abstract

A sheet inverting and stacking system in which a rotatable sheet stacking unit receives the lead edge area of an incoming sheet and then rotates and releases that lead edge for stacking the sheet inverted; with a bail system, actuated by the rotation of the rotatable sheet stacking unit, to vertically press down the lead edge area of the sheet being released at the registration position; the rotatable sheet stacking unit releasing the lead edge of the sheet being released for the stacking at a position under the bail system and slightly above the top of the stacked sheets. The stacking tray is vertically movable for being maintained at a level with the top sheet of the stack thereon closely spaced below the sheet lead edge release position. The bail system also holds the sheets for set stapling in a set stapling position.
