Abstract (en)

[origin: EP0704249A1] The distributor consists of a nozzle (24) with its walls forming a cavity which ends in a lengthwise slit, and a powder delivery system with a main feed duct (6), a divider (7) and a series of secondary ducts (8), at least some of which have a pneumatic modulator for the powder/gas flow. The modulator forms part of regulating loop which is linked to a coating quality or thickness monitor, and has an auxiliary gas feed duct to the secondary ducts and equipped with a gas flow or pressure regulator. Each secondary duct ends in an injector (9), the injectors being set at regular intervals along a line in the cavity inlet. The cavity also has a pressurised gas injector.
