APPARATUS AND PROCESS FOR MAKING COATED FASTENERS ABSTRACT OF THE DISCLOSURE Disclosed is an apparatus for applying patches of resin to internally threaded articles having openings at both ends comprising a support for positioning the internally threaded articles for processing, means for heating the articles to a temperature above ambient temperature and means for providing a stream of fine particles of the resin entrained in a gaseous jet. A spray guide applicator is provided for directing the stream of resin particles through the opening at one end of one of the articles against an area of the threaded portion of the one article to cause the resin particles to be retained by the articles and to adhere to the threaded portion area. The applicator comprises an elongated conduit portion and a nozzle portion, the conduit portion having a passageway therein, and the nozzle portion having top, bottom and side walls, the bottom wall having an opening communicating with the passageway. A slot opening is disposed in the sidewall in a plane forming substantially a right angle to the passageway, the top wall forming a deflector surface for the stream of resin particles, whereby the stream of resin particles is directed in a line of discharge against the threaded portion of the article in a controlled manner. The invention also comprehends the process associated with applying such patches.
