A doctoring apparatus for doctoring a roll surface comprises a doctor blade, a blade holder for applying the doctor blade to the roll surface, and a doctor back having a support surface on which the blade holder is adapted to slide. A locking bar is subdivided into multiple mechanically interlocked segments and is mounted by fasteners on the support surface of the doctor back for movement lengthwise in opposite directions between locked and unlocked positions. The locking bar is configured and dimensioned to fit loosely within a groove on the underside of the blade holder. In its unlocked position, the locking bar permits the blade holder to slide on the doctor back support surface into and out of an operative position adjacent to the roll surface, hi its locked position, the locking bar releasably secures the blade holder in its operative position.

Appareil de raclage pour racler une surface de rouleau comportant une racle, un porte-racle pour appliquer la racle à la surface du rouleau et un arrière de racle possédant une surface du support sur laquelle le porte-racle est adapté de façon à coulisser. Une barre de verrouillage est subdivisée en de multiples segments mécaniquement solidaires et montée par des attaches sur la surface de support de l~arrière de racle pour permettre des mouvements longitudinaux dans des sens opposés entre des positions verrouillées et déverrouillées. La barre de verrouillage est configurée et dimensionnée pour s~ajuster de manière lâche dans une rainure sur le dessous du porte-racle. En position déverrouillée, la barre de verrouillage permet au porte-racle de coulisser sur la surface de support d~arrière de racle pour aller et venir d~une position opérationnelle adjacente à la surface du rouleau. En position verrouillée, la barre de verrouillage fixe de façon amovible le porte-racle à la position opérationnelle.
