Device for assembly of insulating glass sheets with an interior filled with a heavy gas
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 ).
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.
