ABSTRACT:
A method and apparatus for forming sealing and/or retaining elements on a wide variety of fastening devices is provided. The fasteners are conveyed on fastener nests each having a chamber, a fastener lock and a fastener release that are moveable relative to each other. The fasteners then have material applied to them which is cured while the fasteners are in the nests on the conveyor. The fasteners with the sealing and/or retaining element formed thereon are then removed therefrom. A novel fixture for holding fasteners to be processed and an element sealing device having a fastener with a resilient sealing element adhered to a portion thereof with a depression formed therein in close proximity to a portion of the fastener is also provided.
