Apparatus for spraying workpieces and intercepting overspray

摘要

A spray booth provided with a horizontally oriented nozzle for the surface-coating (e.g. coloring) of suspended workpieces passing by on a transporter is provided with an upright stationary screen intercepting excess coating material. The screen is spaced from the floor of the booth so as to enable the continuous circulation of two wipers therearound, one of them ascending behind the screen while the other descends on its front surface facing the nozzle. The screen is overlain by a sprinkler depositing solvent on its front surface to keep the intercepted coating material in a liquid state.
