Abstract
In rotary coating apparatus for coating a substrate, the apparatus includes a rotatable bell cup coating applicator affixed to the distal end of a rotatable drive shaft driven by a turbine, and including a source of supply of suitable coating material, a source of pressurized air for driving the turbine, a second source of pressurized air for creating and directing a curtain of air circumferentially and externally about the bell cup to shape and control the diameter and pattern of the coating material applied to the substrate. More specifically, the apparatus includes multiple air channels formed therein and through the apparatus through which the drive air and the shaping air are conveyed to and through the turbine to (1) drive the turbine and (2) to control the shape and pattern of the applied coating.
