Abstract (en)
The powder coating cabin comprises a tunnel (10) with a spray device (2) positioned at the tunnel entrance above the conveyor belt (3) and at the inlet for the air suction device (4, 5), for applying coating powder to flat work pieces (1) and the belt. Excess powder present is sucked up from the air along the length of the belt, right up to the tunnel exit, and the exit for the air suction device leads to a powder recovery system comprising a cyclone or filter. Flat work pieces such as smooth, optionally perforated and bent or easily deformable sheets or strips are powder coated using electrostatic or tribostatic techniques.
