ABSTRACT:
A printing machine spray device for moistening surfaces of cylinders, rolls, rollers which are rotating around a transverse axis of the machine and/or for moistening the material being printed which is moving in the longitudinal direction of the machine. The liquid is sprayed by two sprayers onto the surface to be moistened while the two sprayers are being moved in respective opposite directions transversely over the surface. Each sprayer starts from a different respective longitudinal side of the machine. Controls determine the on-off delivery of spray, the speed of sprayer motion, the starting positions of each of the sprayers and may adjust these for machine parameters. Automatic dosing of a specific quantity during one spraying is provided. The input to a sprayer may be from one of selected sources.
