Aparatus and method for coating fasteners
Abstract:
Apparatus and method employed in applying a useful coating to fasteners is disclosed. Particularly, a resin material in powder form is preferably applied to a selected surface of the fastener to cover a desired length of the threads of the fastener. The apparatus includes a support for moving the fasteners deposited thereon to a position where the coating is applied, and a positioning device is provided to insure that the fastener is peripherally located for application of the coating. A cam mechanism associated with a plurality of tubes provides movement of the tubes for application of the resin material to the fasteners. The fasteners are subsequently removed from the support by fluid pressure.
