An apparatus for doctoring a roll surface (5) including a pivot bar (12) adapted to be mounted on a doctor back (20) and which the pivot bar defines an upwardly projecting fulcrum (14). A first shelf (26) projects forwardly beyond the fulcrum (14) and a top plate (28) pivotally supported on and projecting forwardly beyond the fulcrum (14) overlies the first shelf (26). The top platen (28) is held downwardly against the fulcrum (14). Blade support members (36) are carried by and cooperate with the top plate (28) to define forwardly open slots (40), which slots (40) are configured and dimensioned to receive a rear edge of a forwardly projecting doctor blade (42). The blade support members (36) have rearwardly projecting second shelves (44) underlying the first shelf (26) and a loading mechanism (50) is interposed between the first and second shelves (26, 44) for pivoting the top plate (28) on the fulcrum (14) in a direction urging the doctor blade (42) against the roll surface (5).
