Method of and system for painting exposed can edges

Abstract From the Canadian patent

At least one complete surface of at least one metallic part of a can is given a uniform coating of corrosion-preventing paint and this part is subsequently worked such that the metal of the part is exposed at regions at least immediately adjacent the coated surface. Dots of paint are sprayed by the ink-jet method substantially only to the exposed regions of the part after working thereof and so that the dots together form a continuous layer covering the exposed regions. According to the viscosity of the paint the surface coating can be achieved by partially overlapping adjacent dots of the applied paint or without overlapping by the running together of the adjacent dots of the liquid, with …
