Abstract
Apparatus is provided for the fluidized bed electrostatic coating of workpieces, especially those of continuous length, such as metal wires. The apparatus includes a control grid (normally grounded), which spans the coating chamber and establishes an electrical effect which densifies and regulates the cloud of charged particles therewithin. Objects (also normally grounded) passed through the cloud so produced may therefore readily develop a uniform deposit upon all exposed surfaces.
