Abstract: A head for a rotary turret machine for making incandescent lamps or fluorescent light tubes is capable of, sequentially, sealing a mount to the lamp envelope, exhausting the interior of the envelope, filling it with a fill gas and tipping-off the exhaust tube of the mount. The head accordingly includes a sealing burner, a tip-off burner disposed coaxially within the sealing burner and around the exhaust tube with the lead-in wires disposed between the sealing and tip-off burners, a coupling connectable to a vacuum pump or to a source of fill gas, and respective fuel pipes for the sealing and tip-off burners.
