PURPOSE:To ensure the safety of operation and also facilitate the installation and removal operation of a bead jig, by making the bead jig held by a bead jig-holding part to alternately enter the reach of the hands of an operator who is apart from a heating means and a burning base through reciprocation of a movable table. CONSTITUTION:The constitution is set up in such a way that plural electrodes 1 which are inserted into bead jigs 3 and fixed are alternately positioned at an implanting and sticking position for a bead glass 2 and also at two places of the Both ends of the movable table 8, are formed bead jig-holding parts 8a, 8b, by means of which said bead jigs 3 are held. And, a driving means 9 composed of cylinder device is coupled with the movable table 8. Therefore, the movable table 8 makes reciprocating travel toward the direction of arrows A, B in accordance with the action of the driving means 9. |
