Abstract
A high-speed integral machine for fabricating substantially contaminant-free, high-intensity discharge arc tubes. The machine comprises a turret having a plurality of arc tube body holding members mounted about the peripheral portion of the turret. A plurality of work stations are located about the periphery of the turret. The turret is indexed in a stop-and-go fashion so that each of the plurality of arc tube holding members is sequentially indexed from work station to work station. Utilizing this device the fabricating operations for high-intensity discharge arc tubes are completed on one turret without substantial cooling of the arc tube between fabricating steps and the possible introduction of impurities therein.
