ABSTRACT OF THE DISCLOSURE A doctoring apparatus employs a doctor blade having a length greater than the face length of the surface being doctored. A blade holder applies an inter- mediate portion of the blade to the doctored surface. The blade is movable longitudinally through the blade holder, and has continuing portions extending beyond the ends of the holder. At least one clamp acts on one of the continuing blade portions. The clamp is adjustable between a closed setting preventing relative movement between it and the blade, and the open setting permitting such relative movement. A drive reciprocates either the blade holder or the clamp in one direction when the clamp is closed and in the opposite direction when the clamp is opened, thereby causing the blade to move incrementally in one direction across the surface being doctored.
