Abstract
An apparatus for doctoring a roll surface including a pivot bar adapted to be mounted on a doctor back and which the pivot bar defines an upwardly projecting fulcrum. A first shelf projects forwardly beyond the fulcrum and a top plate pivotally supported on and projecting forwardly beyond the fulcrum overlies the first shelf. The top platen is held downwardly against the fulcrum. Blade support members are carried by and cooperate with the top plate to define forwardly open slots, which slots are configured and dimensioned to receive a rear edge of a forwardly projecting doctor blade. The blade support members have rearwardly projecting second shelves underlying the first shelf and a loading mechanism is interposed between the first and second shelves for pivoting the top plate on the fulcrum in a direction urging the doctor blade against the roll surface.
