A device for producing heavy gas-filled insulating glass sheets (62, 64, 60) has two plates (4, 6), between which the insulating glass sheet (62, 64, 60) which is to be filled can be located. On the vertical edges of the plates (4, 6) there are sealing devices (12) to seal the space (10) between the

A device for producing heavy gas-filled insulating glass sheets (62, 64, 60) has two plates (4, 6), between which the insulating glass sheet (62, 64, 60) which is to be filled can be located. On the vertical edges of the plates (4, 6) there are sealing devices (12) to seal the space (10) between the plates (4, 6). On the lower edge of the plates (4, 6) there are a conveyor means (40) for insulating glass and a channel (44) for the supply of heavy gas into the space (10) between the plates (4, 6) and into the interior (60) of the insulating glass sheets (62, 64, 60). In one of the plates (4, 6) there is a seal (20) which extends solely transversely to the plane of the plate (4) from bottom to top essentially vertically and which is located for example in the (lengthwise) middle of the plate (4).

The invention claimed is: 1. Device for producing heavy gas-filled insulating glass sheets comprising: two essentially vertical plates positioned on opposite sides of at least one conveyor for an insulating glass sheet which is to be filled with heavy gas; and at least one seal oriented essentially vertically in a space between the plates; wherein the seal is movable solely perpendicular to a plane of the plates; and wherein on two vertical edges of the plates there are additional seals for sealing the space between the plates to the outside. 2. Device for producing heavy gas-filled insulating glass sheets comprising: two essentially vertical plates positioned on opposite sides of at least one conveyor for an insulating glass sheet which is to be filled with heavy gas; and at least one seal oriented essentially vertically in a space between the plates; wherein the seal is extensible from and retractable into a vertically extending groove via movements solely perpendicular to the plane of the plates, said vertically extending groove being provided in a central region of said plates. 3. Device for producing heavy gas-filled insulating glass sheets comprising: two essentially vertical plates positioned on opposite sides of at least one conveyor for an insulating glass sheet which is to be filled with heavy gas; and at least one seal oriented essentially vertically in a space between the plates; wherein the seal is extensible from a vertically extending groove via solely linear motion in a first direction and retractable into said vertically extending groove via solely linear motion in a second direction opposite to said first direction, said vertically extending groove being provided in a central region of said plates.
