ABSTRACT:
A suction head for feeding sheets in sheet-processing machines from a stacked pile of sheets to further sheet transporting means includes suction separation devices for lifting sheets off of a pile of sheets and transport suction devices for taking over the lifted sheet lifted by the suction separation devices and advancing the lifted sheet in a transport direction towards the further sheet transporting means. Control means are provided for moving the separation suction devices in the transport direction for at least part of the transport distance at the same velocity as the transport suction devices whereby the suction separation devices assist in transporting the lifted sheet over the aforementioned part of the transport distance.
