Abstract
A method of multiple powder coating wherein articles to be coated are fed to a conveyor which comprises a pair of Geneva gears secured to both ends of a rotatable shaft. The Geneva gears have a plurality of channels around the periphery thereof for holding the articles. The gears are rotated intermittently at an interval of one channel and an article to be coated is fed to a pair of channels at every Y intermittent rotations, where Y is the number of coatings to be applied. The article is coated once in each cycle of rotation of the Geneva gears and is removed following X times Y intermittent rotations, where X is the number of channels around the periphery of each gear. X is odd when Y is even and X/Y is a decimal when Y is odd.
