Abstract
A spraying system for applying a coating to articles includes a spray booth having a back, a reciprocating spray gun, and an exhaust fan to pull atmosphere from within the spray booth through said back to collect undeposited spray coating material and to exhaust solvent vapors released within the spray booth. The back is movable and has a vent opening having an area substantially smaller than the area of the back, the remainder of the back being impervious to booth atmosphere. The spraying system also includes means for reciprocating the movable back in synchronism with the reciprocating spray gun so that said vent opening is maintained directly before the spray gun during operation.
