Claim:
Method for assembling insulating glass panes that are filled with a gas different from air, by arranging a first glass sheet and a second glass sheet, provided with a spacer, in a vertical or inclined position so that they are positioned one opposite to the other, to form a glass sheet arrangement having a bottom edge and two upright edges, without the first glass sheet being in contact with the spacer, forming a chamber that encloses a space between the glass sheets, by providing a belt at the bottom edge of the glass sheet arrangement and at least one seal beside each of the upright edges of the glass sheet arrangement, which seal extends from a point above the belt down to the belt, introducing a gas different from air into the chamber from below and closing the insulating glass pane by approaching the glass sheets one to the other once a desired filling grade or filling level has been reached, wherein one of the two glass sheets is held at a spacing from the belt during introduction of the gas different from air and that the gas different from air is introduced into the chamber through a gap between the belt and a lower edge of said one glass sheet while the latter is kept in spaced arrangement.
