ABSTRACT:
An automatic coating apparatus has a plurality of nozzle devices movable in X-, Y-, and Z-axis directions along tracks over a workpiece to be coated. One of the nozzle devices is displaceable with respect to the other nozzle device. Different coating materials are ejected from the nozzle devices toward the workpiece. Each of the nozzle devices has a nozzle which can be opened and closed by a valve operated by a cylinder mechanism. While a coating material is being ejected from one of the nozzle devices, the other nozzle device is closed. By thus selectively opening and closing the nozzle devices, the different coating materials can be coated successively on the workpiece.
