Abstract:
An apparatus for transporting single sheets through a device for exposing or printing the single sheets, including a drum, and a processing station having a processing gap, with each single sheet being exposed or printed in the processing station, and with means for transporting each sheet in a circular path past the processing gap, comprisingat least one belt unit for pressing the single sheets against the drum, the belt unit including a plurality of parallel extending continuous belts that are mutually decoupled in their movement and that are driven exclusively through coupling with the drum surface, each of said belts having a curved portion conforming to the surface of said drum and/or a sheet pressed against the drum by the belt, whereby the speed of a belt is greater than the speed of said drum surface when a sheet is between the drum and belt so that a sheet being transported around the drum is not subject to unequal forces when it is engaged by fewer than all of said belts.
