ABSTRACT:
In a paper making machine, apparatus for cleaning a doctor blade which extends across a roll of the paper making machine in the cross-machine direction includes a frame mounted for oscillating movement over the length of the doctor blade, which frame is driven by drive apparatus preferably in the form of an air cylinder whose piston is coupled to the frame to oscillate the same and a blade cleaning brush carried by the frame in a manner such that the brush engages the doctor blade to clean the same as the frame is oscillated by the drive apparatus. The brush preferably comprises a rotatable, disc-shaped brush equipped with an air motor for rotating the same. The present invention provides the capability of cleaning the doctor blades of paper machines without necessitating interruption of the machine operation.
