A device for the detachable fixing of a holder for a doctor blade located in a paper production plant, it being possible for the doctor blade, which is assigned to a supporting or guiding roll for the wire, for the felt or for the paper web, to be set in its position with respect to the supporting or guiding roll by way of an actuating device and, furthermore, it being possible for the holder for the doctor blade to be displaced on a support for the holder by way of a guide at least approximately in the axial direction of the supporting or guiding roll and fixed on the support in the operating position. A pressure hose is disposed between the holder for the doctor blade and the support. The pressure hose allows the holder for the doctor blade to be clamped to the support.

L'invention concerne un appareil pour fixer de façon non permanente un dispositif de retenue de racle dans une papeterie de façon à ce que ladite racle, qui est attribuée à un rouleau de soutien ou de guidage d'une bobine de toile, de feutre ou de papier, puisse être mise en place, par rapport au rouleau de soutien ou de guidage, au moyen d'un actionneur. Il faut en outre qu'il soit possible de déplacer ledit dispositif de retenue de racle sur un support de telle sorte que celui-ci puisse être mis dans une position au moins quasi axiale, par rapport à l'axe du rouleau de soutien ou de guidage et assujetti au support en position d'exploitation. Un tuyau de pression est disposé entre le dispositif de retenue de racle et le support. Le tuyau de pression permet de fixer le dispositif de retenue de racle contre le support.
