Abstract

Mittels einer Einrichtung an einem Sprühfeuchtwerk (2) werden Ablagerungen an Austrittsöffnungen von Düsen (6) verhindert. Das geschieht dadurch, daß in Drehrichtung (A) des zu besprühenden Zylinders (1) gesehen, vor den Düsen (6), eine sich in achsparalleler Richtung des Zylinders (1) erstreckende, auf die die Mantelfläche (11) des Zylinders (1) umgebende Luftströmung wirkende Rakeleinrichtung (29,38) angeordnet ist.

Figure 00000001
A device on a spray dampening unit (2) prevents deposits on the outlet openings of nozzles (6). This is done by looking in the direction of rotation (A) of the cylinder (1) to be sprayed, in front of the nozzles (6), one in the axis-parallel direction of the cylinder (1), onto which the lateral surface (11) of the cylinder (1) doctor blade device (29, 38) acting around the air flow is arranged.
