Equipment for cleaning rubber cylinders of continuous printing machines

Equipment for cleaning the rubber cylinders (C1, C2) of continuous printing machines, characterized in that it comprises means (17, 18) for causing a very small quantity of liquid for cleaning the said cylinders to be sprayed in a controlled and uniformly distributed way on to a sufficiently long portion of cloth, which, including the area directly acted on by the said sprayed liquids, is kept in uniform and distributed contact with a transverse portion of the surface of the cylinder to be cleaned, and which is pushed into close and uniformly distributed contact with the rotating cylinder, upstream and downstream of this portion, by a rectilinear deformable strip (6) and by a rectilinear deformable presser (9) respectively, each of these having a convex surface facing the cylinder, the whole being arranged in such a way that the cleaning liquid acts through the cloth on the cylinder to be cleaned in an extended, uniform and progressive way, and in very small quantities, and in such a way that the liquid is conveniently retained in the cleaning area by means of the said cloth and the said rectilinear pushing elements, so that it does not fall off and so that it is transferred to the dirt on the cylinder in a gradual and controlled way, while the presser (9) facilitates the penetration of the liquid into the direct and promotes the elimination and removal of the said dirt by its contact surface which is characterized by a low-relief configuration, to provide better distribution of the cleaning liquid, to provide a better mechanical action for cleaning the cylinder and to enable a large quantity of the paper particles, which constitute the dirt removed from the cylinder, to be retained in its channels.
