This invention relates to a method and assembly for loading the doctor blade of a doctoring unit used, e.g., in coating a paper web, characterized in that the blade can be loaded close to the edge of the blade without compromising the accuracy of blade profile control. The blade is loaded by means of a backing member (8) having a Z-shaped cross section in which one side of the section forms a base (13), while the middle part forms a waist (18) which turns toward the base (13), and the other side (12) of the shape forms tip (12) pointing to an opposite direction relative to the base (13) and has at its end a tapering edge suited for pressing against the doctor blade (7). This approach is capable of eliminating the sliding movement of the backing member (8) relative to the blade which tends to impair the accuracy of blade pressure control.
