METHOD AND APPARATUS FOR MANUFACTURING CATHODE RAY TUBE

摘要

The cathode ray tube manufacturing method comprises the steps of holding the cathode ray tube bulb and inserting and holding the electron gun at a predetermined position in the neck portion. An annular burner is positioned which has an inner peripheral surface with a number of burner holes formed in the entire area along a circumferential direction. The inner peripheral surface is coaxially located outside the neck portion and opposes the stem of the electron gun. The burner formed to be capable of being divided into halves in a radial direction. Flames are injected from the burner holes toward the neck portion.
