Abstract

A method for surface treating a continuous flow of workpieces includes the steps of fluidizing a stationary bed of surface treating media, aggitating the fluidized bed of surface treating to create a scrubbing action to the surface treating media, suspending the workpieces from an overhead conveyor located over the bed of surface treating media and moving the workpieces to be treated suspended from the overhead conveyor through the stationary, fluidized aggitated media bed subjecting the workpieces to the scrubbing action of the media. Further, an apparatus for surface treating workpieces which includes a reservoir for containing a bed or pool of surface treating media, a force vibration generating device for imparting a reciprocating force to the reservoir and therefore, the surface treating media contained in the reservoir, the reciprocating force having at least a vertical vector and an overhead conveyor means located over the reservoir for conveying the workpieces to be treated continuously through the reservoir and, therefore, through the media.
