<p>PURPOSE:To peel a safety panel which is stuck to a panel front side of a cathode-ray tube by a simple work without damaging the panel. CONSTITUTION:Regarding a cathode-ray tube 5 wherein a safety panel 3 is stuck to the front side of a panel 2 through a resin layer 4, at the time when the safety panel 3 is peeled, the surface of the safety panel 3 is heated rapidly by a plane infrared-ray heater 6 to raise the temperature of the resin layer 4 close to the melting point of the resin by the thermal conduction and then a spatula 7, etc., is inserted between the safety panel 3 and the resin layer 4 from outside to peel the safety panel 3.</p> |
