Abstract
An arrangement for doctoring a belt or a soft roll surfacing in a paper or board machine includes a doctor set in connection with a surface with a doctor blade fitted in it for doctoring the surface. The doctor blade is at least partly of a material, the hardness of which is essentially equal to or less than the hardness of the material of the surface, in order to prevent the doctor blade from cutting into the surface. The material is arranged to form a layer extending over the entire width of the doctor blade, and the thickness of which throughout is at least half of the thickness of the doctor blade. A support construction is arranged in the doctor blade, which together with the layer is arranged to form the doctor blade.
