Abstract
Apparatus for automatically spraying the sides and the top of workpieces such as vehicle bodies as they are conveyed through a spray station. Separate apparatus is provided for spraying the two sides and the top of the conveyed workpiece. Each apparatus is capable of moving one or more spray guns both in a direction transverse to the movement of the conveyed workpiece and towards and away from the conveyed workpiece, and of rotating the spray guns about two axes to direct the spray guns perpendicular to the surface being coated.
