Abstract (en)

[origin: WO0029704A1] 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.
