ABSTRACT:
The process allows a uniform layer of glass particles, forming the preform, to be deposited on the internal wall of a supporting tube rotated around its axis. A suitable relationship is provided to determine the temperature distribution in the deposition zone. The apparatus makes use of different types of heat sources for generating inside the tube a temperature with the distribution required by the process.
