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.
Claims6
Apparatus for transporting single sheets to a device for printing on said sheets, comprising:
- a print drum,
- first means for pressing a sheet against the drum,
- second means for pressing a sheet against the drum, the first and second pressing means being spaced apart to form a processing gap extending across substantially the entire width of the sheet whereby printing of the sheet is enabled from edge to edge across the processing gap, and
- first and second guide means associated with said first and second pressing means, respectively, each said guide means extending across substantially the entire width of the sheet, said first guide means being mounted to be movable to first and second positions with respect to the surface of the drum, in the first position the guide means maintain the leading edge of a sheet in contact with the drum as said leading edge moves past the processing gap, and in the second position the guide means permit the trailing edge of the sheet to lift off of the drum as it approaches the processing gap.
