An electrostatic flocking system having a supply hopper for controllably entraining flock fibers within a propelling air stream, and for feeding the entrained fibers to an electrostatic flocking gun. The fibers and propelling air pass through the gun and into a nozzle at the front of the gun having an elongated forwardly open chamber. An elongated electrode is carried within the nozzle chamber and is coupled to a suitable electric power source for electrostatically charging the fibers and for directing them forwardly over the entire length of the chamber toward the surface of an article being coated.
