Each spray nozzle is operated to either apply a partial coating, a complete coating or several coatings to each article. The apparatus also includes timing screw and a turret conveyor which are rapidly stopped by means responsive to article jamming, and means are provided for facilitating the removal of jammed articles from a housing of the timing screw.
