Abstract:
Apparatus for processing flat substrates by means of a corona station, comprising:a) at least one electrode which can be connected to a high-voltage supply via connecting means,b) a housing device which at least partly accommodates the electrode and its connecting means,c) at least one counter-electrode of cylindrical shaped construction,d) at least one device having at least one feed unit and two extraction units for producing a gas flow which essentially has a directional component for the counter-electrode, the flat substrate bearing against the counter-electrode and being deflected from a feed direction into a direction deviating from the feed direction and being led away,characterized in that in each case at least one extraction unit is provided on the inlet side of the substrate into a corona space formed between the electrode and counter-electrode, and on the outlet side of the substrate from the corona space, and in that the extraction units can be adjusted onto the path of the web of the substrate.
