ABSTRACT:
To produce insulating glass panes (10) filled with heavy gas, an insulating glass pane (10) still open at least in the area of its lower edge is filled from underneath with heavy gas. To do this the two vertically oriented edges of the insulating glass pane (10) are sealed by seals (30, 31). The upper edge of the insulating glass pane is not sealed. At at least one site (156, 157) in the area of the lower edge, the heavy gas from a channel (122) which runs along a belt conveyor (9) which supports the insulating glass pane (10) is blown via openings which pass between side-by-side portions of the conveyor belt of the belt conveyor (9), into the insulating glass pane (10). To adjust the effective length of the channel (122) to the length of the insulating glass pane (10) to be filled with heavy gas, a piston (130) is contained in the channel. As soon as the space between the glass sheets (11, 13) of an insulating glass pane (10) is entirely filled with heavy gas, the insulating glass pane (10) is closed. In this way insulating glass panes, even if they are not rectangular, can be produced in a short cycle time and filled with heavy gas with low gas losses.
