ABSTRACT:
A method of coating articles comprises providing a plurality of coating dispensing devices at each station in a coating material application line, each device being connected to a common source of coating material. Coating material is dispensed fron only one device while measuring the flow rate of coating material therethrough. When the measured flow rate falls below a predetermined threshold, flow through the device is automatically terminated and switched to another device. Apparatus for practicing the method includes a plurality of dispensing devices connected to a common coating source through respective flow rate sensors. A programmable logic control station connected to the sensors and the devices is used to control the operation of the dispensing devices.
