ABSTRACT:
An improved apparatus is disclosed for controlling the build on wire moving in a vertical electrostatic fluidized bed which has opposing vacuum chambers for controlling the position of the cloud of powder in the bed. Each vacuum chamber is provided with an opening to the atmosphere and with means for controlling the size of the opening. By "spoiling" the vacuum in this manner the position of the cloud can be more precisely controlled thereby producing a more uniform coating on the wire.
