Abstract
A method for manufacturing an optical fibre, in which a preform is inserted into a furnace; the preform is drawn via an outlet of the furnace; and the drawn preform has a working area including a structure composed of walls, and gas streams are applied to the two opposite faces of these walls, which streams run along the walls in opposite directions, so as to subject the walls to a shear force of gas streams counter-propagating on either side of the walls. A device for manufacturing an optical fibre is also provided.
