Abstract: An apparatus for cleaning a coating gun nozzle used in spraying the inner surface of cans with a coating material comprises a cleaning nozzle of a cleaning gun for spraying a cleaning solution onto the spray nozzle to remove oversprayed coating material collecting thereon. The cleaning nozzle is secured to an end of an elongated cleaning gun extension and is positioned above a spray nozzle secured to one end of a coating gun extension for Spraying cleaning solution onto said spray nozzle. Cover sleeves, forming liquid-tight seals with the cleaning and spray nozzles, have removable friction engagement with the cleaning and spray gun extensions to shield the cleaning and spray guns from oversprayed coating material. A control system controls the operation of the coating and cleaning guns.
