Abstract

PURPOSE: To obtain a stem sealing unit for a tube bulb which can regulate accurately the center position of a mount and control the heating position of the mount.
CONSTITUTION: Exhausting tube C of mount A is inserted into holding materials 4 of holding part 2 through hollow position regulating materials 12, and compressed air is sent from air supply tube 8 to expand holing materials, and the inside diameter of them is reduced to hold exhausting tube C. At this time, the inside face of flare part B of mount A contacts with taper part 14 of position regulating materials 12 to regulate the center positon. Then, gas flames are jetted from nozzle hole 16... of burner part 15 to heat flare part B, and simultaneously, support rod 1 is advanced to insert mount A into a bulb (not shown in the figure) and bring flare part B into contact with the aperture edge of the bulb, thereby sealing. By moving burner part 15 in the axis direction relatively to holding part 2 and position regulting materials 12, the heating of mount A is controlled.
