Abstract

An apparatus for use with a device for producing a suitable electric field to effect the electrodynamic spraying of solutions, dispersions, or mixtures of solids. The apparatus includes at least one spray station for spraying into a given spray zone. Each spray station includes two spaced apart tanks for holding the medium to be sprayed and which are disposed on both sides of the spray zone. An endless band is supported by pulleys disposed at each tank for circulating the band and constantly running a run thereof through the tanks. Squeegees are disposed at each tank to remove excess medium from the band and inlet and outlet connections in each tank effect a desired level of the medium therein.
