Abstract
An ionizing device generates ionizing lines to shape solvent borne coating material being dispersed from an electrostatic rotary atomizer. A band having a clamping element affixes the device to the electrostatic rotary atomizer. A halo is affixed to the band by at least one support arm. The halo includes a plurality of generally conical members spaced therearound, each generating ionic lines to shape the atomized coating material being dispersed from the rotary atomizer. A shroud is positioned around each of the generally conical members to shape the ionizing lines being generated to form an ionic field to improve the transfer efficiency of the electrostatic rotary atomizer.
