  • Coating material supply nozzle
    Publication number: 20030197076
    Abstract: A coating material supply nozzle has a coating material reservoir where a coating material fed from the outside into a nozzle body, and an elongated nozzle port, from which the coating material passed through a nozzle passage is discharged. A coating material feed pipe for feeding the coating material is mounted in the coating material supply nozzle to extend in said coating material reservoir over the entire length. The coating material feed pipe is provided with at least one coating material feed bore for guiding the coating material within the coating material feed pipe into the coating material reservoir uniformly in a lengthwise direction of the coating material reservoir.
