ABSTRACT:
An apparatus and method are described for coating a glass container with a substantially uniform thickness of a viscous curable plastic coating material. The article being coated is first dipped into a bath of the plastic coating material while gripped at the finish or closure portion, and is drawn upwardly through an air knife apparatus in accordance with the invention, which provides a shaped air flow that removes the excess coating material from the surface of the article, and leaves a coating of uniform thickness thereon. The coating is then cured to a hardened state.
