Patent

CA 2634210

A method and apparatus for manufacturing an optical fiber comprising the steps and/or means of: drawing a fiber from a heated preform, by applying a pulling force to the fiber; spinning the fiber while it is drawn, wherein the step of spinning the fiber com-prises the sub-steps of winding the fiber on a spin roller by a winding arc, Such that a friction force is generated between the fiber and the spin roller resulting from said winding arc and from said pulling force; axially displacing said spin roller such that the fiber is caused to roll over the spin roller surface by said friction force.

L'invention concerne un procédé et un appareil permettant de fabriquer une fibre optique comprenant les phases et/ou les moyens suivants : étirage d'une fibre à partir d'une préforme chauffée, en appliquant une force de traction à la fibre ; filage de la fibre pendant son étirage, la phase de filage de la fibre comprenant les phases auxiliaires d'enroulement de la fibre sur un galet centrifuge par un arc d'enroulement, de telle sorte qu'une force de friction est générée entre la fibre et le galet centrifuge résultant dudit arc d'enroulement et de ladite force de traction ; déplacement axial dudit galet centrifuge de telle sorte que la fibre va rouler sur la surface du galet centrifuge sous l'effet de ladite force de friction.
