A treatment equipment, which is intended to be installed in connection with a moving surface. The treatment equipment includes a frame and a blade holder formed from composite material as a single piece and connected to the frame. In addition, a blade is fitted to the blade holder, the bevelled edge belonging to which is arranged to be brought into contact with the moving surface by moving the blade holder. In the blade holder, there is also a separate backing blade, which is fitted at one edge into the blade holder, the other edge extending closer than the blade holder to the said bevelled edge.

Treatment equipment

A blade holder for a doctor and method for using the doctor is disclosed, in which in the front part there is a throat or similar for the doctor blade of the doctor and which blade holder has loading members connected thereto to press the doctor blade against the surface to be doctored. The blade holder further includes a relatively stiff, slightly flexible frame plate, which incorporates the attachment flange. The blade holder also includes loading devices for directing the force of the loading members onto the frame plate at a distance from the attachment flange, to bend the frame plate and thus press the doctor blade against the surface to be doctored.
