Title (EN) CUTTING AND GRINDING APPARATUS FOR A GLASS SHEET EDGE
(FR) APPAREIL DE COUPE ET DE POLISSAGE D'UN BORD DE FEUILLE DE VERRE
Abstract:
(EN) The invention relates to a cutting and grinding apparatus for a glass sheet edge, comprising a grinding machine (5) which includes two rotatable glass-supporting tables (10) and displacement guides (11) for shifting tables (10) aside from a conveyor track (6) included in a primary conveyor (6, 7, 8). Two grinding heads (12) are mounted on the outer ends of displacement guides (11) of said tables (10) and a displacement mechanism (15) for tables (10) is controlled to carry out the shifting movement of tables (10) between conveyor track (6) and grinding head (12). The same displacement mechanism (15) is also controlled to perform the advancing movement during a grinding operation for maintaining the edge of a glass sheet (9) in contact with a grindstone (13) during the rotation of a glass sheet having a shape other than circular.
(FR) L'invention se rapporte à un appareil de coupe et de polissage du bord d'une feuille de verre, qui comprend une machine de polissage pourvue de deux tables (10) rotatives de support de verre et des guides de déplacement (11) servant à déplacer les tables (10) hors d'une piste de transport (6) comprise dans un dispositif de transport principal (6, 7, 8). Deux têtes polisseuses (12) sont montées sur les extrémités externes des guides de déplacement (11) desdites tables (10), et un mécanisme de déplacement (15) des tables (10) est commandé de manière à provoquer le mouvement de déplacement des tables (10) entre les pistes de transport (6) et la tête polisseuse (12). Le même mécanisme de déplacement (15) est aussi commandé de façon à produire le mouvement de progression au cours d'une opération de polissage afin de maintenir la feuille de verre (9) en contact avec une pierre à adoucir (13) au cours de la rotation d'une feuille de verre dont la forme est autre que circulaire.
