Title
(EN) METHOD AND SYSTEM FOR PRODUCING PLASTIC OPTICAL FIBER
(FR) PROCEDE ET SYSTEME DE PRODUCTION DE FIBRE OPTIQUE EN PLASTIQUE
Abstract
(EN) A method and system are described for continuously producing plastic optical fiber. The method involves melting a polymeric starting material in a continuous screw extruder and then extruding the melted polymer vertically upward (i.e., against the force of gravity) to form a plastic optical fiber with a uniform core cross section.
(FR) L'invention concerne un procédé et un système destinés à la production continue d'une fibre optique en plastique. Le procédé consiste à faire fondre une matière de départ polymérique dans une extrudeuse à vis sans fin, puis à extruder le polymère fondu verticalement vers le haut (c'est-à-dire dans le sens opposé à la force de gravité) en vue de former une fibre optique en plastique présentant une section transversale de coeur uniforme.
