ABSTRACT:
Apparatus (74) and method are provided for electrostatically depositing particles (64) of a first material onto a sheet (18) of a second material, and for electrostatically neutralizing the residual charge. The apparatus (74) includes a particle generator (20) for aspirating particles (64) of the first material, electrodes (60a and 60b) for electrostatically charging the particles (64) to a first polarity, an electrode (75) for electrostatically recharging a portion of the particles (64) to the opposite polarity, and a depositing chamber (22) for electrostatically depositing the particles of the opposite polarity subsequent to depositing the particles of the first polarity.
