CA 2286042

A gripper (16) grips an end of a preform (8) and pulls it down at a constant velocity as measured by a measurer (12). Since the preform (8) is heated by furnace (4), the preform stretches. This process creates an optical fiber preform rod of controlled diameter.

Dans cette invention, un préhenseur (16) saisit une extrémité d'une préforme (8) et tire cette extrémité vers le bas à une vitesse constante, mesurée par un appareil de mesure (12). Ce faisant, la préforme (8) est chauffée par un four (4) et par conséquent s'étire. Ce procédé permet de créer une tige préforme à fibres optiques ayant un diamètre régulé.
