Abstract

In coating devices for paper or cardboard webs (2) having a doctor blade (3) as dosing element, flexible pressure strips (5) that rest on the doctor blade (3) are used to allow the contact pressure of the doctor blade (3) to be regulated. The pressure strip (5) has a surface moment of inertia (lx?) measured in the perpendicular direction to the flexure plane comprised between 100 mm?4 and 5000 mm?4, preferably between 800 mm?4 and 1200 mm?4. A locally differentiated contact pressure can thus be regulated without causing coating irregularities at high speeds of the web. The adjusting elements for the pressure strip (5) have an axially movable adjusting rod (8) guided by a holder (7). The ends of the adjusting rod (8) push a prestressed pressure spring (12). An adjustable screw (16) coaxially arranged with respect to the adjusting rod (8) presses against the force of the spring (12) in the direction of the web (2).
