PURPOSE:To enable the formation of a glass film of uniform thickness by allowing the base for depositing a glass film thereon to get near or away to the oxyhydrogen flame at the top of the burner, as it is rotating. CONSTITUTION:Base plates 2 for a glass film to be deposited are arranged on the surface periphery of the turn table 3 rotating at a constant speed and glass fine particles are blown from the deposition nozzle 7 on the top surfaces of the bases 2 to form a glass film on each base plate. At this time, the system is provided with a transferring unit (consisting of, e.g., a control motor 16, screw mechanism 15, moving bed 14, and shaft 20) which can allow the turn table 3 as well as the base plates 2 on the turn table 3 to get near or away to the deposition nozzle 7. |
