Abstract: The inside of a sleeve is positioned over a nozzle having an elongated groove opening immediately at the region of the sleeve to be striped. The sleeve surrounding the nozzle is given a predetermined potential level. A stream of particles is introduced into at least one end of the groove in a direction at least generally parallel to the groove and to the region to be striped. The particles are charged relative to the potential level of the sleeve such that the particles are attracted to the sleeve.
