Summary:A print shop paper handling machine (2) is used with a rotary printing machine (1). It lifts the top sheet from a stack of paper and feeds it to the next rotary print process. The paper is lifted by a number of suction pads operated at different pressures. On lifting the sheet from the stack and during the associated onward transport motion, the sheet is so held that there is relative motion between it and the suction pads. The trailing edge is held up especially by a drag suction unit, improving the slide action. Bei einer Vorrichtung zum Trennen des obersten Bogens von einem Bogenstapel einer Bogen verarbeitenden Maschine, insbesondere Bogenrotationsdruckmaschine, ist es vorgesehen, Hub-/Trennsauger einzusetzen, die mit Unterdrücken unterschiedlichen Niveaus beaufschlagt werden, so daß ein vom Bogenstapel angehobener Bogen bei einer Transportbewegung in Richtung Bogen verarbeitender Maschine derart hochgehalten wird, daß dieser gegenüber den Hub-/Trennsaugern eine Relativbewegung ausführt.
