  • Method and apparatus for splitting a cathode ray tube
    Patent number: 6089433
    Abstract: A scratch is made at least at one corner portion of the cathode ray tube and heat is applied so as to flank the scratch from the two sides. More specifically, electrical heating wires are disposed at the two sides of the scratch formed on the cathode ray tube and the electrical heating wires are used to apply the heat in a linear manner from the two sides of the scratch. Preferably, scratches are formed at the four corners positioned at the panel portion rather than the frit glass portion where the panel portion and the funnel portion of the cathode ray tube are joined, electrical heating wires to which tension is applied are disposed at the four side positions of the panel portion so as to flank the scratches from the two sides, and heat is applied to the cathode ray tube by the electrical heating wires. Tension is applied to the electrical heating wires by springs.
