Abstract
Lubricating material is applied to a fast moving strip within a vertical deposition chamber having smooth side walls and a roof slanted at an acute angle with respect to the side walls on each side of the chamber at its top. A plurality of sources of lubricating particles are spaced in each side of the deposition chamber intermediate its top and bottom. Each of the sources includes a horizontal chamber outside of the deposition chamber and opens into the deposition chamber. Each of the sources have a plurality of compressed air atomizers supplied from a supply of lubricating material in said horizontal chamber and are adapted to remove the larger particles of lubricating material from said spray and to urge the remaining smaller particles into the deposition chamber by the residual flow of compressed air from said atomizers. Lubricating particles flow slowly and without significant momentum into the deposition chamber. Electrostatic electrode means supported at each end by the end walls of said deposition chamber on each side of its central plane are connected with a source of high electrical potential to charge and deposit the randomly moving particles of lubricating material. Means adjacent the openings at the top and the bottom of the deposition chamber balance the pressure of the atmosphere within the deposition chamber so that the gas from within the chamber flows only through the opening at its bottom.
