Abstract
In a doctor device comprising a doctor blade which is applicable to a plate cylinder of a printing press and is located in a doctor holder, the holder is pivotally connected to a beam parallel thereto by at least one leaf spring. A plurality of piston-cylinder units disposed on the beam in a row have their piston rods applied directly or indirectly by way of pressure bolts to the holder or a part connected thereto. The piston-cylinder units are fed by a pressure medium at an adjustable basic pressure. Each piston-cylinder unit is associated with a separately adjustable fine regulating valve by way of which an additional pressure can be superimposed on the basic pressure by introducing additional pressure medium.
