ABSTRACT:
A continuous, automated method and apparatus for transporting and electrostatically powder coating articles such as fasteners. Articles in an unoriented state are oriented one behind another, transferred in succession to and magnetically retained on a face of a rotating feed wheel at a first position with respect to the feed wheel, transported to a second position by rotation of the feed wheel, transferred in succession at the second position to a respective portion of a moving conveyor, and releasably suspended magnetically and electrically grounded at the respective portion of the conveyor. Magnets used to suspend the articles from the conveyor are shielded from direct contact with the articles to avoid coating the magnets. While the articles remain suspended magnetically from the conveyor by their end portions, they are conveyed through a coating booth where they are electrostatically powder coated.
