ABSTRACT:
A high voltage charge at very low amperage is impressed on a bath of oil or other lubricant in a dielectric header through a submerged electrode. A grounded high speed moving metal strip attracts streams of the charged bath across its width through apertures or slots provided in the header. Pressurized air jets directed at these streams disperse the streams into a multitude of finer crossing streams which coat the strip completely and evenly. A recovery system for the oil or other lubricant is provided.
