Apparatus for application of polymer resin onto threaded fasteners

Abstract

An apparatus is disclosed for the application of a polymer resin to a threaded fastener, where the fastener includes a cylindrical body and the threads of the fastener are formed in a bore extending diametrically across the body. The apparatus generally comprises a conveyor, a resin application station and a fastener orientation station. The conveyor carries the fasteners along a predetermined path of travel, and includes one or more fastener support members that permit the individual fasteners to rotate about the axes of their cylindrical bodies. The application station comprises a nozzle which directs a stream of the resin toward the travel path of the fasteners. The orientation station includes a guide member which operates to rotate each of the fasteners relative to the conveyor as they move toward the application station, and to thereby properly orient the fasteners so the threaded bore of each fastener will intersect the resin stream as the conveyor carries the fasteners along the travel path and through the spray station.
