Abstract:
A method for dusting strip- or sheet-shaped products, the method comprising the steps of:a) disposing at least one spray nozzle at a substantial separation from the product to define a gap; b) spraying a powder/air mixture on the product at a deposition area, wherein said powder can be magnetized, said powder spreading in said gap to generate a deposition area having a size substantially greater than an output diameter of said spray nozzle; c) conveying the product past said spray nozzle in a transport direction; and d) disposing a magnet means below the product, said magnet means having a first pole disposed below the product proximate said disposition area, and a second pole disposed below the product downstream of said first pole in said transport direction to generate a magnetic field in a region of said gap between said spray nozzle and the product, said magnetic field exercising a downward force on said powder along said transport direction between said first and said second poles.
