Abstract

A stacked-sheet prefeeder comprises a sheet guiding device for receiving therein a stack of sheets, an intermediate tray, a scale former for removing sheets, arranged in a stack and/or in a scalelike mode of arrangement, jointly from the lower surface of the stack received in the sheet guiding device and for introducing these sheets into the intermediate tray in a first direction of movement, a sheet separator for removing from the intermediate tray the respective lowermost sheet as a single sheet in a second direction of movement which is substantially opposed to the first direction of movement, and a guide means arranged in the intermediate tray and used for guiding the sheets in the intermediate tray at their sheet edges constituting the front sheet edges in the second direction of movement, the guide means being implemented as a transport and guide means in such a way that it moves the sheet edges constituting the front sheet edges in the second direction of movement in the interior of the intermediate tray to the sheet separator.
