Abstract: An apparatus for transporting single sheets through a device for exposing or printing the single sheets, with a drum and means that press the single sheets against the drum, with a processing station having a processing gap, with the single sheets being exposed or printed in the processing station, includes means that limit the processing gap. According to the invention, a belt unit is provided that presses the single sheets against the drum, with the belt unit having a plurality of parallel extending continuous belts that are mutually decoupled in their movement and can be driven exclusively directly or indirectly through coupling with the drum surface.

Abstract: An apparatus for transporting single sheets through a device for exposing or printing the single sheets, with a drum and means that press the single sheet against the drum, with a processing station having a processing gap, with the single sheets being exposed or printed in the processing station, includes means that limit the processing gap. According to the invention, the means for limiting the processing gap are moveable so said the distance between the drum and the means for limiting the processing gap can be increased or decreased.
