Abstract
Examples relate to a sheet-fed rotary printing machine including a coating unit, which includes an impression cylinder and a further cylinder forming a contact zone therewith. The coating unit comprises a charging device for electrostatically fixing sheets on the impression cylinder, which includes an electrode unit that is directed toward the outer cylindrical surface of the impression cylinder. A charging core zone includes a region of an outer cylinder surface of the impression cylinder that is located next to the electrode unit. The charging core zone is arranged downstream from the contact zone and upstream from a transfer point leading away from the impression cylinder. An electrode of the electrode unit has a minimum first distance with respect to the impression cylinder of between 4 mm and 13 mm and a minimum second distance with respect to the further cylinder of between 4 mm and n 35 mm.
