Abstract:
An apparatus for the application of a resin coating to fasteners, comprising:a powdered resin reservoir having a discharge conduit terminating in a free end so that powdered resin discharged from the reservoir falls under the force of gravity in a falling powdered resin stream of predetermined configuration; a conveyor for supporting and transporting a plurality of the fasteners through said resin stream; a vacuum nozzle positioned adjacent to the free end of the discharge conduit so that, as the conveyor moves the fasteners through the falling resin stream, each of the fasteners is positioned between the free end of the discharge conduit and the vacuum nozzle, the vacuum nozzle being adjustably positionable relative to the path of travel of the fasteners through said falling resin stream, the position of the nozzle being adjustable to control the amount of powdered resin retained on the fasteners; and a heater positioned adjacent the conveyor to heat the powdered resin retained on the fasteners thereby fusing the resin into a coherent coating on the fastener.
