Patent number: 4949637Abstract: A dampening system for a lithographic press in which a train of rollers delivers dampening fluid from a dampening fluid pan to the plate cylinder of the lithographic press is provided. The train of rollers comprises a hard rubber pan roller, a rubber transfer roller of medium hardness, and a relatively soft rubber water form roller. The transfer roller is mounted in parallel relation to the pan roller and can be moved towards or away from the pan roller in order to vary the pressure therebetween and to thus meter the dampening fluid delivered to the plate cylinder. Dampening fluid is conveyed from the pan roller, to the transfer roller, to the water form roller, and finally to the plate cylinder. The pan roller and water form roller are driven at the surface speed of the plate cylinder through a gear train.Type: GrantFiled: December 9, 1988Date of Patent: August 21, 1990Inventor: James J.
