Abstract
An apparatus and method for use with powdered resin feeders provides a continuous stream of powder to a plurality of threaded or non-threaded fasteners. In one preferred embodiment, the apparatus generates a gravity induced powder stream at the free end of a discharge conduit which is intersected by a series of fasteners carried on a conveyor. A vacuum nozzle is positioned adjacent to the powder stream and the conveyor. Both the vacuum nozzle and the free end of the discharge conduit are adjustably positionable relative to the path of the fasteners carried on the conveyor.
