Abstract:
A powder coating apparatus and method are provided for feeding fine powdered coating material such as thermoplastic type material to a succession of discrete articles passing by the apparatus. The invention also provides a powder feed system that deposits an excess of powdered coating material than that required to form the coating and provides for recirculation of the powder not ultimately used to form the coating back to the powder feeding apparatus.
