Abstract
The invention relates to a doctor device, associated with a contact surface, in particular a rotating roller. The doctor device has a doctor blade, provided for placement against the roller, for bringing the doctor blade into contact with the roller by way of a pressurized fluid. At least one sensor is provided on the doctor blade, for generating a measured value for the contact pressure of the doctor when it is placed against the roller. There is a control unit which controls the speed at which the doctor can be placed against the contact surface, in particular the roller.
