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.

This suction chamber fixing the substrate is arranged close to the lifting region. Examples also relate to a printing machine comprising this machine assembly.
