Abstract
Apparatus for the metered coating of a printing machine roller with a liquid application medium, in particular for the metered coating of an ink applicator roller with printing ink, containing at least one doctor roller placed with its working surface onto the printing machine roller and carried by a doctor roller bed. The doctor roller is slide-mounted on its working surface by means of at least one sliding surface formed on the doctor roller bed. The application medium can be fed to or discharged from the surface of the printing machine roller by rotation of the doctor roller, through a clearance between the sliding surface and the working surface of the doctor roller. A pressure-regulatable valve for regulating the pressure prevailing in the clearance is arranged between a pressure source for the application medium and the clearance.
