Abstract

In the process for operating a coating apparatus, it is provided for changes in the angle of the coating edge of a doctoring element, for example in relation to the horizontal, to be directly detected by means of a signal transmitter which is mounted on the doctoring element 1 in the vicinity of its coating edge 18. This signal transmitter can operate on an electromagnetic basis so that the signal is transmitted in a wireless fashion to a receiver. An inclination switch is preferably provided, said switch detecting small deviations of a desired angle of the coating edge 18 in relation to, for example, the horizontal by means of the displacement of a mercury bead and two electrodes which are shortcircuited by the mercury bead. <IMAGE>
