Abstract
Abstract An automatic coating and printing machine wherein can bodies and like tubular members are atuomatically positioned on mandrels and thereafter serially presented to coating and printing blankets wherein the necessary coating and printing is effected thereon with the mandrels being rotated as the can bodies carried thereby contact the blankets of the coating and printing cylinders to transfer coating and printing materials to the can bodies. Thereafter, the appropriately coated and printed can bodies are automatically transferred from the mandrels to another conveyor. The mandrels are so mounted wherein when no can body is on a mandrel, the mandrel does not come into contact with the printing or coating blankets. The inking mechanism for the printing machine is designed to apply a uniform coating of ink to the printing drum by a drum inking roll which first has a heavy ink coat applied thereto followed by a second light smoothing ink coat over the heavy coat in advance of the printing drum.
