Abstract
A device for atomizing and dispensing a first liquid coating material onto a first group of one or more articles to be coated by the first coating material and then for dispensing a second liquid coating material onto a second group of one or more articles to be coated by the second coating material. The device includes at least one atomizer providing a first flow rate of the first and second coating materials required for high quality atomization of the first and second coating materials, and a second outlet providing a second and substantially greater flow rate of the first and second coating materials and lower quality atomization than the first atomizer, or no atomization. A first conduit couples the second outlet to the first atomizer. A second conduit couples the first atomizer to a source of fluid to be dispensed. A valve controls the flow of liquid to the second outlet. Operation of the valve between dispensing of the first coating material onto articles to be coated thereby and dispensing of the second coating material onto articles to be coated thereby, coupled with dispensing of a flushing medium through the first and second conduits, flushes excess coating material simu…
