Abstract
A method for controlling the deflection and/or position of a deflection-compensated doctor blade support beam relative to a web. The movement range of the doctor blade support beam is divided into radial control sectors so that the working directions of compensation elements in the support beam essentially form interface limits of the radial control sectors. When the support beam is to be moved, a set point is selected toward which a reference point of the support beam should move. The specific control sector is then determined within which the set point is located and this control sector becomes the active control sector. Deflection of the doctor blade support beam employs these two compensation elements so that one is used for controlling the deflection in the x-axis direction of the coordinate system, while the other is used for controlling the deflection in the y-axis direction of the coordinate system.
