ABSTRACT:
An apparatus and method for applying a resin coating to a plurality of discrete portions of a fastener, such as both internal and external threads. A conveyor supports a fastener. The fastener is first transported past a heater and then past a first powdered resin spray assembly. Powdered resin, supplied to the first spray assembly by a resin reservoir, is used to generate a first air-borne powdered resin stream which coats one set of threads with resin when the fastener traverses the resin stream. The conveyor also transports a second resin spray assembly through the first air-borne powdered resin stream. The second spray assembly uses a resin receiver to aspirate the air-borne resin. The resin is then used to generate a second powdered resin stream which coats the other set of fastener threads.
