ABSTRACT:
A manufacturing apparatus includes an endless chain traveling along a prescribed path. A plurality of holding chucks for clamping a stem tube or bulb are fitted to the chain and moved along the path. A mount-making unit is arranged near the path and seal a pair of leads to the stem tube held by the chuck to make a mount. A sealing unit is arranged near the path. The unit takes up the mount from the chuck passed the mount-making unit and then seals the mount in the bulb held by the chuck. An evacuating unit is arranged near the path. The unit evacuates the bulb held by the chuck which is passed the sealing unit, introduces an inert gas into the bulb, and then seals the bulb.
