Abstract
An apparatus for controlling the tilt angle of a doctor blade comprising two support blocks for a doctor blade supporting beam, a first actuator by which the supports are movable about their bearing points, a blade supporting beam pivotally mounted between upper parts of the support blocks having a doctor blade attached to the beam, and a second actuator by means of which the blade supporting beam is movable about its pivoting point in order to control the tilt angle and loading of the blade. In accordance with the invention, the first actuator is arranged to rest against a guiding surface of a guiding cam permanently arranged to the pivoting point of the blade supporting beam. The arrangement in accordance with the invention provides a simple and reliable method for blade angle control.
