ABSTRACT:
The present invention generally relates to an electrostatic coating apparatus for spraying a stream of particles onto a medium, and in particular to an apparatus equipped with a powder coating suspension device such as a multivolume chamber, or a air stream creation device. What is also contemplated is the use of a plurality of variable openings in the enclosure, used in conjunction with a plurality of conductors, to dispose a stream of particles onto a moving medium in successive layers. In yet another embodiment, the stream of particles is directed in a directional electrical field created by electrodes placed adjacent to directional shields. The present disclosure relates to an in-line industrial device able to coat paint, starch, thermoplastic materials, or any other powder material onto a medium by successively controlling a plurality of parameters.
