To permit easy interchangeability of a doctor blade unit which could be a 'throw-away' or 'recyclable' item, the doctor blade unit and a carrier element (8) on the printing machine are formed with interengaging plug-and-socket connections formed, respectively, on the carrier element (8) and the rear wall (2) of the chambered doctor blade unit (1), in which the plugs can be hollow plugs or pipe stubs, secured to and projecting from the carrier element (8) snugly fitting into reception openings (13) formed in the rear wall (2) of the chambered doctor blade unit.
