Nozzle cleaning system including spray gun cover for can coating system

An apparatus for cleaning a spray nozzle in combination with a coating gun having a coating gun extension with a spray nozzle secured to one end for spraying a can with a coating material, said apparatus comprising:

• cleaning gun means for spraying a liquid cleaning solution on said spray nozzle of said coating gun whereby oversprayed coating material is cleaned from said spray nozzle;
• said cleaning gun means including a cleaning gun having a cleaning gun extension with a cleaning nozzle secured to one end for spraying said cleaning solution onto said spray nozzle;
• a first cover sleeve comprising a first tubular body defining an internal passage adapted to be in surrounding relationship with said cleaning gun extension to shield said cleaning gun from oversprayed coating material whereby said first tubular body substantially covers the forward portion of said cleaning gun except for said cleaning nozzle;
• and
• a second cover sleeve comprising a second tubular body defining an internal passage adapted to be in surrounding relationship with said coating gun extension to shield said coating gun from oversprayed coating material whereby said second tubular body substantially covers the forward portion of said coating gun except for said spray nozzle.
