Abstract: A method for depositing controlled quantity of particles on a substrate comprises providing aerosolized particles in a deposition zone having first and second electrodes, and creating an electrostatic field between the first electrode and the second electrode to create a pool of ions at the first electrode, charging particles within the deposition zone with the ions, and moving the particles towards and depositing the particles onto the substrate. In order to prevent excessive charge build up on the substrate, the electrostatic field is periodically reversed.

Abstract: The invention relates to a device for the powder-dusting of moving objects, particularly flat substrates in the form of webs and sheets of paper, plastic or textile with a nozzle housing made of electrically insulating material, with at least one nozzle provided on the housing for releasing a powder air stream laden with dusting powder and with metallic electrodes and counter-electrodes disposed on the housing for producing an electrical high-voltage field. To obtain a powder air stream with powder particles as neutral as possible, it is envisaged that at least one electrode and a counter-electrode cooperating with the latter are disposed on the outside of the housing in the vicinity of the nozzle whereby an electrical high AC voltage is applied to the electrode and counter-electrode, whereby, after being released from the nozzle, the powder air stream penetrates the thus produced high AC voltage field on the outside of the housing.
