Method and device for treating substrates

The invention relates to a method and a device for treating substrates. The aim of the invention is to provide a method and a device for treating substrates which are modular and versatile in use. The aim is achieved in that a device for treating substrates (1) comprises a feeder (7) and one or more first sub-structure modules (100) which each comprise a pressure cylinder (41) with means for fixing a lift (5) and a sheet-conveying device and one or more second sub-structure modules (101) which respectively have a transport cylinder (3) with openings (12) formed in the cover surface thereof, and means for fixing a lift (5) and a sheet conveying device. All first and second sub-structure modules (100, 101) have the same intersection points for connecting the sub-structure modules (100, 101) on the inlet and/or exit side and can be equipped and/or are equipped with an attachment module.
