ABSTRACT:
Heat activated means are provided for applying areas of external pressure to the periphery of the panel portion of a cathode ray tube envelope during heat processing. The pressure is directly related to the heat cycle to which the tube envelope is subjected, and induces a state of compression in particularly the panel portion thereby minimizing the occurrence of implosions.
