A method of forming an evacuated glass panel which facilitates the placement of a pump-out tube close to one edge of the finished panel. First and second glass sheets (12 and 13) are assembled in face-to-face spaced-apart relationship, with the first sheet (12) having an edge portion (33) that extends beyond the corresponding edge portion (34) of the second sheet. A pump- out tube (18) is provided in the first sheet at a location adjacent the corresponding edge portion (34) of the second sheet. The first and second sheets (12 and 13) are sealed around their edges to form a chamber (15) which is evacuated by way of an evacuating head (10). Following the evacuation process, the pump-out tube (18) is closed and the edge portion (33) of the first sheet is trimmed so as to lie adjacent the corresponding edge portion (34) of the second sheet.
Procédé permettant d'obtenir un panneau de verre sous vide qui facilite l'installation d'un tube de mise sous vide près d'un bord du panneau fini. Les première et seconde plaques de verre (12,13) sont assemblées face-à-face et espacées, la première plaque (12) ayant une partie bord (33) qui s'étend au-delà du bord correspondant (34) de la seconde plaque. Un tube de mise sous vide (18) est placé dans la première plaque, à un endroit adjacent à la partie bord (34) correspondante de la seconde plaque. Les première et seconde plaques (12,13) sont scellées le long de leurs bords de manière à former une enceinte (15), mise sous vide grâce à un dispositif d'évacuation (10). A l'issue du processus d'évacuation, le tube de mise sous vide (18) est bouché et le bord (33) de la première plaque est découpé de manière à être adjacent à la partie bord (34) correspondante de la seconde plaque.
