Abstract

L'invention concerne un dispositif 10 de traitement de section d'extrémité pour plaques de verre, équipé d'une base de support 11 pour supporter une plaque de verre G, d'une unité de traitement 13 pour soumettre la section d'extrémité Ge de la plaque de verre G à un traitement prescrit pendant que celui-ci est supporté par la base de support 11 et d'une section de couvercle 16 pour recouvrir l'unité de traitement 13, La base de support 11 présente une première partie de support 20 pour supporter la région centrale G1 de la plaque de verre G et une deuxième partie de support 21 pour supporter la région d'extrémité G2 de la plaque de verre G. La dimension d'épaisseur ts de la deuxième partie de support 21 est réglée de manière à être inférieure à celle de la première partie de support 20 et d'une taille capable de passer à travers une ouverture 19 dans la section de couvercle 16 pendant que la région d'extrémité G2 de la plaque de verre G est supportée.
