Beschreibung
Zusammenfassung:	The invention concerns a method of and an apparatus for the production of preforms to be drawn into optical fibres, used as light conductors in telecommunications. Main liquid reactants are sent with a liquid oxidant towards a cylindrical support to the attainment of a preform of the required size. Then by chemical and physical means residual water is eliminated and the preform is collapsed to form a cylindrical rod.
