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 coating gun 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 the coating gun nozzle secured to one end of a coating gun extension for spraying cleaning solution onto the coating gun nozzle. Cover sleeves, forming liquid-tight seals with the cleaning and coating gun nozzles, have removable friction engagement with the cleaning and coating gun extensions to shield the cleaning and coating guns from oversprayed coating material. A control system controls the operation of the coating and cleaning guns.
