Abstract: An apparatus and method for electrostatically applying a plurality of particles such as flock to an object. The particles are placed into a hopper at an uppermost portion of the apparatus and are propelled downwardly through a metallic screen to which an unchanging electrical charge is applied. The particles are given a predetermined orientation and continue their downward passage through a metallic grid to which a changing electrical charge is applied. In another embodiment, the flock is propelled in an upward direction through changing and unchanging electrically charged zones. The particles attach themselves to the object in a uniformly dense manner and substantially align themselves in accordance with the electrostatic lines of force.
