  • Method of heating a band for a cathode ray tube and an apparatus therefor
    Patent number: 5899787
    Abstract: A method for heating an implosion-proof band in a process of banding a cathode ray tube (CRT) and an apparatus for heating the band. The band is thermally expanded before it is attached to the outer surface of a CRT. The method includes generating a first high frequency pulse, generating a second high frequency pulse in response to the first pulse, regulating the level of the second pulse, generating a magnetic field in response to the second pulse, and heating the implosion-proof band by locating the band within the magnetic field. The band is uniformly and completely expanded for easy installation while avoiding deterioration of the surface of the band.
