Abstract
A device for applying a lubricant coating to strip material subsequently formed in an operation which necessitates uniform application of the lubricant. Propulsion rolls pull the strip through a lubricant bath and squeeze off excess lubricant to leave a relatively heavy and somewhat uneven coating of lubricant. The propulsion rolls drive the coated strip between metering rolls which have hardened metal surfaces roughened by grit blasting to achieve a uniform, pitted effect. The metering rolls exert substantial pressure on the thickly coated strip and cause separate and independent, limited volume patches of lubricant to be defined and adhere to the strip uniformly across its surfaces.
