Abstract
An apparatus for fusing a polymer powder deposited on a surface of a faceplate panel of a cathode-ray tube comprises a housing having a faceplate support surface and enclosing a chamber. A shutter adjacent to the panel support surface separates the faceplate panel from the chamber. A reservoir for holding a solvent is within the chamber and at least one piezoelectric transducer communicates with the reservoir for atomizing the solvent to create a fog. A fan within the chamber distributes the fog onto the polymer powder. A method for fusing the polymer powder onto the faceplate panel also is described.
