ABSTRACT:
Apparatus for the coating of glass containers has a series of vertical slots for applying coating chemicals to a hot glass jar with a minimal neck and shoulder area. An opposing horizontal slot exhausts spent coating material and reactants in a laminar flow. A center section provides a current of gas without chemicals parallel to the coating stream, and flowing with low velocity relative to the coating stream, but with high velocity relative to the extraneous turbulent and convection currents.
