ABSTRACT:
In a coating device, a doctor blade is bent S-shaped for application of its contact force by means of a pressure bar. An additional force of a profile correction device is exerted for profile correction by means of magnets. This additional force acts preferably opposite to the main contact force. This prevents the profile correction device from causing a change of the geometry of the doctor blade in the contact area of the spreading edge of the doctor blade.
