Abstract
The present specification discloses an apparatus for washing a rubber blanket cylinder of a printing machine. The apparatus comprises a cleaning cloth which extends between a supply roll and a take-up roll, with control and drive means adapted to rotate the take-up roll in a step-wise manner to thus take up uniform lengths of cleaning cloth. A rotatable guide roller is arranged to press the cleaning cloth between said rolls, against the rubber blanket cylinder, the rotatatable guide roller having a resiliently deformable outer surface across which the cleaning cloth is guided. A reversible brush roller is located upstream of the rotatable guide roller in the direction of rotation of the rubber blanket cylinder, and is in contact with said cylinder, and a cleaning agent supply and a water supply are arranged to feed said brush roller. Said control and drive means comprises a crank which acts upon a lever via a connecting rod, said lever being connected to a take-up shaft, in which the take-up roll is mounted, by way of a one-way clutch. The point at which the connecting rod acts upon said lever is variable dependent upon the quantity of cleaning cloth taken up by said take-up roll. The width of the cleaning cloth corresponds only to a portion of the length of the cylinder, and guide and operating means are provided for moving the apparatus transversely along the entire length of the cylinder.
