Abstract

PURPOSE: To obtain a Braun tube having high quality and high explosion-proof performance, by jointing the band steel through non-seal method.
CONSTITUTION: After fixing a lug 2 and reinforcing board 3 on the side wall of Braun tube 1, male mold 10 is applied on one side of reinforcing board 3 while the band steel 4 is fed through field hole 11 to the side wall of Braun tube 1 and heated. Then the field hole 11 is rotated in reverse direction and the band steel 4 is mechanically stretched while fitting to the side wall of Braun tube 1 to overlie the end at the portion of female mold 10. Then the male mold 12 is advanced to be pressed against the female mold 10. Consequently one of band steel 4 is cut by cutter section 13 while simultaneously the overlapping portion is fixed through non-seal jointing by the function of male and female molds 10, 12. Then the female mold is removed and the band steel is cooled to reinforce the stretching force onto the Braun tube through the shrinkage of band steel.
