Abstract:
1. A continuous process for coating a workpiece comprising the steps of: introducing the workpiece into a mouth of a porous coating basket; moving the porous coating basket containing the workpiece through a first side of a coating chamber; sealing the mouth of the porous coating basket with a lid connected to a means for rotating the porous coating basket about its axis; introducing the porous coating basket into a coating tank containing a coating solution such that the workpiece contained in the porous coating basket is immersed in the coating solution; allowing the workpiece to remain immersed in the coating solution for a period of time sufficient to form a desired coating thereon; effecting relative movement between the porous coating basket and the coating to a relative position where the workpiece is no longer contained in the coating solution and at least a portion of the porous coating basket is contained within the coating tank; effecting rotational movement of the porous coating basket to cause excess coating solution to disengage from the workpiece and enter into the coating tank; stopping the rotational movement of the porous coating basket and effecting relative movement between the porous coating basket and the coating tank to a relative position where the porous coating basket is no longer contained in the coating tank; moving the porous coating basket containing the coated workpiece through a second side of the coating chamber different from the first side to a basket unloading station; and removing the coated workpiece from the porous coating basket at the basket unloading station, wherein the porous coating basket is inclined while rotational movement thereof is effected to cause disengagement of the excess coating liquid from the workpiece.
