Abstract: The invention provides an apparatus and method for applying a liquid lubricant to at least one surface of a moving metal sheet. The apparatus includes a wick and a liquid lubricant reservoir and at least one conduit in flow communication with the wick and reservoir. The liquid lubricant moves from the reservoir in controlled amounts, through the conduit or conduits to the wick by gravity flow and is moved by capillary action through the wick to the surface of the moving metal sheet without the application of an external mechanical force, such as a piston, to generate a pressure gradient through the wick to move the liquid lubricant therethrough.
