Abstract
An improved rotary paint atomizing device in the form of a bell and a cover plate which is releasably attached to the front center of the bell. Paint fed along the axis of the device onto a conical projection on the back surface of the cover plate accelerates and flows outward in a radial direction. The cover plate surface is curved so that as the paint flows outwardly, it also flows first forward and then back until it reaches radial slots formed in a peripheral rim on the cover plate where the cover plate contacts an interior bell surface. Paint discharges from the slots onto a conical interior bell surface and flows in wide, closely spaced ribbons which merge into a uniform, continuous thin sheet before it is discharged from the bell edge. As the paint discharges from the bell edge, the sheet produces extremely fine uniform ligaments which break up to produce fine, uniform small paint particles.
