Abstract
Apparatus for continuously cleaning and electrostatically coating an elongated metallic member, which apparatus is especially suitable for uniformly coating copper and aluminum wire having a rectangular cross-sectional configuration. An electrically grounded, rectangular wire is continuously moved in a horizontal plane, while held under constant tension, through apparatus which chemically etches the wire, and which then provides a cloud of electrostatically charged, heat fusible particles about the clean wire. The charged particles are attracted to the grounded wire and the apparatus further includes baffles at predetermined strategic locations in the cloud which provide a uniform deposit of particles on all sides of the wire. The apparatus then heats the wire to a predetermined elevated temperature to melt the particles and cure the resulting film to provide a tenacious insulating coating on the wire.
