Abstract
A lubricator (28) is provided to lubricate tab stock (82) prior to forming the tab stock (82) into pull tabs. The lubricator (28) comprises felt pads (36-38) for removing contaminants from the tab stock (82) prior to lubrication thereof. A hydrostatic chamber (40) receives and disperses lube (42) from a source (44). As the tab stock (82) passes through the chamber (40) the lube (42) coats the tab stock (82). Subsequently, the tab stock (82) passes through wipers (50-52) and metering rollers (58-60) to remove all but a predetermined quantity of the lube (42). A collector (70) is provided to collect any excess lube (42) and return same to the source (44) through a return line (72) thus allowing recycling of the lube (42).
