A device for applying an operating pressure to a roller, especially the counterroller of a unit for spreading a thin layer of material onto a strip, wherein the roller is mounted on support levers by means of eccentric bushings to which are connected pressure applying means operating by rotating the said bushings. The operating pressure is applied to the roller without involving displacements of the support levers, whose position is stationary during operation. Preferably, bars are connected to said bushings, and these bars carry at one end a counterweight, whereas the other ends thereof are connected to pneumatic cylinders, feeded through pressure adjusters, for applying the operating pressure to the roller. |
