摘要： An apparatus for coating internally threaded fasteners, particularly closed end fasteners, such as flanged weld nuts, which includes a powder spray arrangement, has a spray nozzle within a spray cylinder. The spray nozzle arrangement is actuated by an air cylinder to be in abutting relationship with a fastener seated in the spray position. The spray nozzle is tapped for the supply of air and for the supply of powder to the fastener threads. The spray block on which the nut is sprayed has a vacuum line that exhausts excess powder that does not adhere to the threads.

摘要： An apparatus for generating a powder stream to be applied to a work piece includes a powder reservoir, a mixing chamber, a powder metering valve, a transfer conduit, and a nozzle. The metering valve allows control of the powder flow from the reservoir into the mixing chamber where it is dispersed with and entrained in an air flow entering the chamber through an aspirating inlet. The air entrained powder is then conveyed from the mixing chamber via the transfer conduit to the nozzle. The nozzle includes a controllable gas flow input and a powder stream generating passageway configured and associated with the transfer conduit to generate a reduced pressure in the conduit and mixing chamber which draws the air borne powder from the chamber into the nozzle. One or more of the individual components are adjustable to control the size, configuration, thickness or other parameters of the coating on the work piece as a result of the applied powder stream.

摘要： This invention relates to threaded fasteners, an apparatus for making such threaded fasteners and methods of fastening parts. The tip of the shank of a threaded fastener has at least one thread coated with a lubricating or masking material to reduce the drive torque necessary for fastening as well as provide a protective coating for the fastener during subsequent processing operations. The drill tip of the disclosed self-drilling fasteners is coated with a lubricating material to reduce drive torque and to eliminate binding when drilling through fibrous material. The present invention also prevents the build-up of corrosion inhibiting materials on threaded fasteners attached to parts to be fastened together. A masking and/or insulating material is first applied to the threaded fasteners attached to the parts to substantially prevent applied corrosion inhibitor from adhering to the threads of the fastener. A method of fastening parts, including fibrous material such as carpet or sound insulation, is also accomplished through practice of the present invention. The apparatus of the present invention provides a resin type stream entrained in a gaseous jet directed through a nozzle onto the threads of a fastener. The apparatus provides selectable thread coverage, including complete coverage of all threads.

摘要： An apparatus and method for applying locking material to an area of a fastener adapted for internal threading. The apparatus includes a support structure for moving a succession of internally threadable fasteners with support structure recesses positioning the fasteners for treatment. The fastener opening is filled with locking material and the fastener heated to soften the locking material and cause adherence to the internal walls of the fastener. A clearance pin can be used to selectively clear a passageway through the locking material either before or after the heating step. A gas pressure source directs a gas stream toward the opening of the fastener to form a passageway through the locking material attached to the fastener.

摘要： 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.

摘要： A method and apparatus for coating a fastener with head and shank portions is disclosed. The invention includes the steps of and apparatus for transferring the fasteners from a feed mechanism such that the fasteners are positioned for coating. The fasteners are then conveyed through a plurality of operating stations, beginning with a heating station where the shank portions of the fasteners are heated. Subsequently, at a material applying station, a coating material is applied to the heated shank portions. A preferred embodiment of the method and apparatus of the present invention includes using a magnetic holder to carry the fasteners horizontally by their head portions, heating the shank portion to a temperature above the melting point of the applied material and applying the material to the heated shank portion to form a coating thereon. The magnetic holders are part of an endless traveling belt that rotates continually. The fastener carriers have teeth that engage a rack to rotate the fasteners. A conveyor provides added air cooling for the coated fasteners, which can continue to be rotated. Also disclosed is a transfer wheel with two sets of notches that is synchronously coupled to the traveling belt for placing and aligning fasteners on the belt for coating.
