Abstract
The invention relates to a doctor assembly in a paper machine, which is intended to clean, e.g., a roll, and which includes a surface against which a doctor blade is set, a blade support for supporting the doctor blade, a frame, a jointed bearing assembly, which supports the doctor blade and is itself supported from the frame, and which is parallel to the doctor blade, and extends essentially over the entire width of the roll, and loading devices between the blade support and the frame for turning the doctor blade in relation to the frame and for pressing the doctor blade against the surface with a selected pressure. Due to the continuous support, there is essentially no deflection in the doctor assembly, when it is attached by its frame directly to the structures of the paper machine.
