ABSTRACT:
A glassware molding machine having a parison molding portion and a container body molding portion includes a spray apparatus with a spray head that is operatively attached to a spray spindle. Vaporized lubricant is sprayed radially outward from the spray head while the spray head is rotated and moved upwardly through the molding cavity. The automatic cycle of the glassware molding machine is interrupted while the mold halves are closed so that the lubricant is not deposited onto mating surfaces of the mold halves; a barrier of air is provided to prevent lubricant from being deposited onto the parison plunger; a collection system is provided to capture exhaust materials from the application of lubricant to the hot mold surfaces; and provision is made for depositing a heavier layer of lubricant, or a different lubricant, on a selected surface of the molding cavity.
