For filling the insulating glass panes with a heavy gas, one of the glass plates (40) which are to constitute the insulating glass pane is only partly joined to she other glass plate (42) before the assembling, particularly in that said one glass plate is bent so that a gaplike opening temporarily remains between the glass plate (40) and the spacer (41) and the interior space of the insulating glass pane can be filled with a heavy gas through said gaplike opening.

A process is disclosed in which a rectangular spacer frame (16) for insulating glass is automatically manufactured in that a tubular bar is repeatedly bent in a common bending plane (5) and its free ends (19, 20) are joined. One or both end portions of the tubular bar are deflected out of the bending plane (5) during the final bending operation so that the free ends (19, 20) are moved to such positions that said extremities are laterally spaced apart and extend alongside each other. The end portions (17, 18) of the tubular bar are then gripped and moved to positions in which they are axially aligned and spaced apart. The free ends of said end portions are subsequently joined to each other to form the spacer frame (16), which is subsequently transferred to an overhead conveyor (69) in an automatic operation.
