Abstract
L'INVENTION CONCERNE UN PROCEDE POUR FABRIQUER DES CORPS EN VERRE ENROBES. SELON CE PROCEDE, DANS LEQUEL ON DEPOSE SUR LA SURFACE D'UN CORPS EN ROTATION DES SUBSTANCES SE TRANSFORMANT EN UNE COUCHE DE VERRE, AVEC CREATION D'UN CHAUFFAGE LOCAL DU CORPS, ON MODIFIE LE SENS DE ROTATION DU CORPS PAR RAPPORT A LA DIRECTION DANS LAQUELLE LA ZONE DE CHAUFFAGE PARCOURT LE CORPS ETOU UN NOUVEAU PARCOURS DU CORPS PAR LA ZONE DE CHAUFFAGE COMMENCE POUR UNE POSITION ANGULAIRE DU CORPS QUI EST MODIFIEE PAR RAPPORT A LA POSITION ANGULAIRE DUDIT CORPS AU DEBUT DU PARCOURS PRECEDENT. APPLICATION NOTAMMENT A LA FABRICATION DE FIBRES CONDUCTRICES DE LUMIERE.
