摘要： A fastener, and a process and apparatus for coating fasteners, in which a resin type material is applied to the fastener is disclosed. A stream of resin type material is directed to each fastener and the threads of each of the fasteners, the threads may be covered over an arcuate variable length including complete 360.degree. coverage. The resin type material applied may be a masking material, a lubricating material and/or an insulating material enabling an accurate and consistent torque-tension characteristic to be maintained during coupling of the fastener in a variety of post-processing environments. Furthermore, the resin type material applied to the fastener is substantially resistant to the deposition of corrosion resistant or preventative materials.

摘要： The present invention is directed to a process for the application of fluoropolymer to a preselected area of a threaded fastener, and particularly to substantially all of the threads of the fastener. The fluoropolymer is supplied to a spray nozzle in powder form and is subjected to a triboelectrostatic charging process so that individual particles discharged from the spray nozzle are electrically charged. In the preferred form of the invention, the fluoropolymer powder is triboelectrically charged, entrained in an air stream discharged from the nozzle and directed onto the preselected area of the fastener. In this manner a generally uniform powder coating is deposited onto the preselected area of the fastener while the fastener is maintained at room temperature. Thereafter, the fastener is heated to a temperature above the melting point of the fluoropolymer to thereby coalesce the deposited powder into a continuous film coating which adheres, upon cooling, to the pre-selected area of the fastener. In accordance with a preferred embodiment, the fastener is heated in a manner which raises the temperature of only the preselected area of the fastener to the fluoropolymer melting point. This preferred heating technique minimizes the retention of fluoropolymer inadvertently deposited on areas of the fastener other than the preselected area, and allows this undesired fluoropolymer to be easily removed, even after heating.

摘要： A mechanism and process for coating tapped holes in specialty articles having varying external configurations, such as metal stampings. The specialty article is positioned in a preselected orientation at a loading station, and is then engaged by a carriage assembly and moved from the loading station to a heating station, and then to a spray and discharge station. During movement between stations, the article is maintained in the preselected orientation to allow proper heating and spraying of the tapped holes.

摘要： A powder spray apparatus for coating threaded fasteners capable of operating at an optimum spray condition. Air supply and powder supply tubes communicate within an air/powder entrainment block. The jet diameter of the air supply tube is sized to provide an optimum spray condition at which a constant supply of powder is provided through a powder spray tube at an optimum powder density and velocity. These powder density and velocity conditions maximize the powder build rate on the threads of the fastener, and also increase production rates. The resulting coated fasteners exhibit a low torque scatter, and a highly uniform patch. A method for operating a powder spray apparatus at the optimum spray condition also forms part of the present invention.
