Recirculating powder applicator

Abstract

A recirculating powder applicator includes an applicator body having an inlet on an upstream surface and an outlet on a downstream surface, wherein the inlet and outlet define a passage that extends transversely through the thickness of the applicator body, a powder conduit, an air inlet, an exhaust aperture located on one of the upstream or downstream surfaces, and a circulation chamber located on the interior of the applicator body. The powder conduit and air inlet are in fluid communication with the passage and the passage is in fluid communication with the circulation chamber. A method of applying powder to a substrate during a continuous process includes using a recirculating powder applicator.
