ABSTRACT:
A method of manufacturing a cathode ray tube employs an assembly of a frit jig and a flexible bolt for use during the aligning and sealing process of the glass cone and display screen components of a cathode ray tube. The flexibility provided by the bolt reduces the risk of damage to the glass parts of the cathode ray tube during the heat steps involved in the sealing process. Preferably, the bolt comprises a resilient metal pin that is flexible in a direction transverse to the longitudinal axis of the bolt. The bolt comprises a hollow part having a central bore with an opening and a head, the central bore extending substantially parallel to the longitudinal axis of the bolt, and the metal pin being comprised in the hollow bolt. The metal pin extends from the head through the bore over a length larger than that of the bore.
