Cleaning of electrostatically coated articles without wiping

Abstract From the Canadian patent

An apparatus and method are provided for producing a coating of resinous material upon only a portion of a workpiece the resinous material, preferably being deposited upon the workpiece as electrostatically charged solid particles. One zone of the workpiece is contacted in the substantial, absence of relative movement therebetween with cellular, resiliently deform-, able contact surface of a particle removal member to pick up particles of the resinous material therefrom without wiping or brushing the surface.
