Abstract

Procédé pour la formation d'un filament en verre de haute pureté à l'aide d'un mandrin sensiblement cylindrique. On applique un premier revêtement de suie de verre à la surface périphérique extérieure du mandrin, on enlève ce dernier pour former une préforme de suie dans laquelle est ménagée une ouverture, on chauffe la préforme à une température suffisamment élevée et pendant une durée suffisante pour permettre à la suie de s'agglomérer au moins à une extrémité de celle-ci, et l'on étire simultanément la portion agglomérée de la préforme pour en réduire la section et occlure ladite ouverture, formant ainsi un filament. Application à la fabrication de guides d'ondes optiques.
