ABSTRACT:
An apparatus for applying a coating to the head-shank junction of externally threaded fasteners in an automated fashion. The fasteners are positioned, head down, on rotating part holders positioned about the periphery of a rotating disc. The part holders may be magnetic or other forms, and are adapted to maintain the fasteners in a generally fixed position during their movement. The fasteners are pre-heated at a heating station during their rotational movement on the disc. A dispenser is then used to apply the coating to the articles, in timed sequence to the movement of the articles. In this fashion, a coating can be applied to selected portions of the entire periphery of the head-shank junction. A method for applying a coating to the head-shank junction of externally threaded fasteners in an automated fashion also forms part of the present invention.
