ABSTRACT:
An apparatus in which the loading and unloading of sheets on a tray used in a printing machine is facilitated. The uppermost sheet of the stack of sheets on the tray is continuously maintained at a preselected level as additional sheets are loaded on the tray or removed therefrom. This optimizes the operator access level and minimizes the delay time associated with the tray moving from the sheet feeding position to the operator access level.
