Abstract
A flat spray nozzle for a powder spray gun comprises a nozzle body formed with an axial powder flow passageway, a pair of spaced powder discharge slots intersecting the powder flow passageway and a bore located between the powder discharge slots. The bore in the nozzle body receives an electrode which extends forwardly of the spray nozzle, between the powder discharge slots for electrostatically charging particulate powder material emitted from the powder discharge slots without disrupting the spray pattern of particulate powder material.
