Abstract
Abstract Method and apparatus for selectively masking surfaces of various length stator cores or the like, while other selected surfaces are being coated by a fluidic controlled coating nozzle. A circumferential series of ribs on a core support structure sandwich ported pads which pass coolant fluid to the selected core surfaces to prevent coating material buildup on the core. The ported pads are provided with laterally extending grooves at spaced longitudinal locations along their outer surface to restrict conductive heat transfer longitudinally therealong. Insulation between the ribs and pads restrict the conductive transfer of heat from the pads to the ribs. Fluid control signals to the coating nozzle selectively direct coating material through the nozzle to the other core surfaces or return the constantly flowing coating material to the pulverant coating material storage and supply area.
