Abstract

969,230. Cleaning press cylinders. AGFA A.G. March 23, 1961 [March 26, 1960], No. 10735/61. Heading B6C. Ink is removed from an offset or blanket cylinder 6 by an apparatus comprising a cleaning roller 22 which is in contact with a roller 17 rotatable within a bath 18 of cleaning liquid. The rollers are swingable about a shaft 11 depression of a key 12a causing the roller 22 to contact the cylinder 6 against a spring 14. Deposition of the ink on the roller 22 is aided by an electrostatic charge generated by the friction arising between the jacket 7 of the cylinder 6-which is of rubber-and the jacket of the roller 22 which is of a high polymer, e.g. silicone rubber, polyvinyl chloride or polypropylene, having a micro-porous structure. The roller 22 must be at a higher positive potential than the cylinder. Establishment of the desired potentials may be effected by connecting the surfaces of the cylinder 6 and the roller 22 to suitable electrical sources and the bath of cleaning liquid with its associated roller may be omitted.
