Abstract: Apparatus for coating wire and the like includes a build control bar that projects horizontally, into the cloud chamber of an electrostatic fluidized bed coating unit, from a supporting carriage. The carriage permits facile movement of the control bar to vary its extension into the coating chamber, and means is provided thereon for changing the angular orientation of the bar by rotating it about its axis, to thereby dispose in working position any of a plurality of longitudinally extending different surface portions. The latter vary from one another in width dimensions and/or configuration, and thereby providing a masking member that can readily be adapted to correspond to the width and/or configuration of a workpiece.

Abstract: Build control means is provided by which the characteristics of a cloud of electrostatically charged particles can readily be altered, so as to produce an optimal deposit upon any of a variety of workpieces. The means described offers a high degree of flexibility of application for the apparatus in which it is employed, and is particularly adapted for use in coating electrical conductors of rectangular cross section.

Abstract: A method and apparatus are disclosed by which electrical conductor cable can be produced utilizing electrostatic coating means, which method and apparatus are highly convenient, uncomplicated and economical to carry out. An outstanding and unique feature of the cable produced in accordance herewith resides in the presence of a web portion of reduced cross-section connecting the individual conductors, by which manual severence of one from another is facilitated. Most desirably, the apparatus and method provide means for producing individual insulating coatings on each of the conductors, which means ideally utilizes an electrostatic cloud coating technique.

Abstract: An apparatus, system and method are provided for the fluidized bed electrostatic coating of workpieces, especially those of continuous length, such as metal wires. The apparatus includes a control grid spanning the plenum chamber and establishing an electrical effect by which deposits of improved uniformity can be produced at lower operating voltages.

Abstract: An apparatus, system and method are provided for the fluidized bed electrostatic coating of workpieces, especially those of continuous length, such as metal wires. The apparatus includes a cloud control grid spanning the coating chamber, upon which may be impressed voltage and/or variable current effects, and which may be modified with depending horizontal conductors, to introduce additional cloud control capability.
