An apparatus is disclosed for the automatic coating of articles. The apparatus has a spray device controlled by a programmed control device. A transport device transports the articles along a predetermined path to a coating position and then away therefrom after coating. A sensor monitors the position of the article and generates signals representative thereof, preferably generating one signal each time the article moves a predetermined distance (e.g. 2 cm.) along the path. A second sensor generates additional signals to the control device when an article passes a predetermined point, also indicating which of several types of articles has been detected. The control device controls the spraying process responsive to these signals. If desired, portions of the article that are moved sequentially into the coating position can be sprayed in different manners, e.g. with the spray devices positioned or oriented differently, or using different coating materials, etc. The control device is preferably reprogrammable.
