Abstract
A doctor blade unit for the inking system of a rotary printing press consists of a doctor blade carrier, on which two doctor blades that can be brought into contact with an inking roller or screen roller are fastened parallel to one another in the approximate shape of a roof, with said doctor blades limiting an ink chamber in cooperation with the inking roller, the doctor blade carrier and sealing elements provided on the ends of said doctor blade carrier. Ducts for supplying and discharging ink into/out of the ink chamber and contacting units for pressing the doctor blade carrier against the inking roller are also provided. In order to ensure that both doctor blades can be pressed against the screen roller with exactly the same contact pressure, the doctor blade carrier is connected to a doctor blade unit carrier that is provided with the coupling rods of parallel pitman systems. The parallel pitmans are coupled to inking system flames or supports of the inking system flames.
