CA 2375193

The invention is a doctor blade system with clamping device for clamping a doctor blade, for example in a doctor blade chamber without using screws and without having to use tools. A clamping mechanism, preferably pneumatic, counteracts the clamping by actuation. By disposing a sectional rail between the clamping rail and the doctor beam, the sectional rail drawing the clamping rail and the beam together with a spring mechanism, the doctor blade is clamped between the clamping rail and the beam. In another embodiment of the invention the clamping rail is designed as an angular section tipping about an edge.

L'invention concerne un ensemble racle pourvu d'un dispositif de serrage servant à fixer une racle sans utiliser de vis et sans qu'il soit nécessaire d'utiliser d'outils. Un mécanisme de serrage, de préférence, pneumatique, s'oppose au serrage quand on le met en service. Le positionnement d'un rail divisé entre le rail de serrage et la tige de la racle, le rail divisé exerçant une traction au moyen d'un mécanisme de ressort afin de rapprocher le rail de serrage et la tige, permet de fixer la racle entre le rail de serrage et la tige. Dans un autre mode de réalisation, le rail de serrage est conçu pour basculer dans une zone angulaire autour d'un bord.
