ABSTRACT:
This disclosure depicts curtain coating apparatus for applying a coating of phosphor or other CRT screen material to the concave inside surface of a curved skirtless cathode ray tube front panel. The apparatus conveys the panel through a curtain of the coating material with its concave surface facing upwardly. The path along which the panel is conveyed (and thus the panel motion) is such as to produce a high degree of uniformity in the coating received by the panel.
