Abstract: A multipiece spray assembly is disclosed which provides an annular axially and radially inwardly inclined nozzle passage operative to rapidly and efficiently apply a substantially complete and uniform coating to the inner surfaces of a forming cavity. Additional nozzle means may also be provided to simultaneously coat an overlying forming tool.

Abstract: A new spray ring apparatus for use in forming apparatus of the type used in metal forming and glassware forming which include a forming cavity into which a fluid lubricant material is sprayed. In one embodiment, the spray ring includes a plurality of nozzles through which the fluid lubricant material is sprayed into the cavity in a tangential helical flow pattern to thereby uniformly coat the interior surfaces of the cavity prior to the forming of the metal or glassware parts therein. In another embodiment, an annular nozzle flowpath is provided with the helical flow pattern being imparted to the lubricant material via a tangentially disposed inlet opening into an annular manifold chamber. A plurality of nozzle openings may be provided in the outer surface of the spray ring which may operate to uniformly coat the outer surfaces of a punch or similar type of associated overlying forming tool.
