ABSTRACT:
A system for lubricating glass forming molds and guide members by flame spraying the molten gobs of glass as they fall to the molds with powdered graphite where the graphite spray is directed from two sides of the falling gob or gobs. Any overspray that does not impinge on the gob or adhere to the gob during the flame spraying of the lubricant is collected by positioning an exhaust header in direct alignment with the flame spray direction to draw the combustion products and powdered lubricant overspray into an exhaust system to keep the area around the feeder clean and free of airborne particles.
The mounting of the burners and exhaust headers on a support which is movable relative to the gob drop path without actually crossing the path facilitates the implementation of the lubricant system of the invention.
