These belt conveyors each have a continuously circulating transport belt and are arranged one after another in the transport direction of the substrates conveyed on the respective transport belt. The substrate to be transferred from the first belt conveyor to the second belt conveyor is lifted off the transport belt of the first belt conveyor by means of an air current generated by a lifting nozzle and an opposing air current generated by a counter-nozzle. The substrate to be transferred remains fixed until its transfer by the vacuum pressure generated by a suction chamber of the first belt conveyor. This suction chamber fixing the substrate is arranged close to the lifting region. Examples also relate to a printing machine comprising this machine assembly.
