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 media to create a scrubbing action to the surface treating media, submerging the workpieces to be treated in the stationary, fluidized, aggitated media bed subjecting the workpieces to the scrubbing action of the media, holding the submerged workpiece stationary within the fluidized, aggitated bed of surface treating media, releasing the hold on the workpiece, and removing the workpiece from the bed of surface treating media. Further, an apparatus for surface treating workpieces which includes a reservoir for containing a bed or pool of surface treating media, a vibration generating device for imparting a reciprocating force to the reservoir, having at least a vertical force vector, to the reservoir and, therefore, to the surface treating media contained in the reservoir, means for passing a gas generally upwardly through the reservoir to fluidize the bed of surface treating media contained in the reservoir, and clamping device for clamping the workpiece in a stationary position in the reservoir.
