<p>An acceleration cell for use in coating substrates with plastic resin particles. The cell includes a housing that has an air inlet port, an air outlet port, and a particle feed port, the latter in association with a resin particle source. The housing receives a carrier airflow for taking up resin particles so that the particles are suspended in the carrier flow. The air outlet port has a configuration having a predetermined width, which generally corresponds to the width of the substrate. The cell also contains at least one electrostatic charger for charging the suspended resin particles and at least one apparatus for accelerating the carrier flow and the suspended particles. Finally, the cell includes at least one flow-modifying apparatus for modifying the resin particle outflow, producing a uniform delivery of the particles across the substrate.</p> |
