An automatic method and device for filling, with gases other than air, insulating glazing units. The method entailinga step for injecting the gas and expelling the air so as to produce a laminar flow through a manifold constituted by the hollow region of the profile that forms the spacer frame. The method and the device allow a considerable saving in costs, reducing the amount of gas required for filling to an amount very close to the volume of the inner space provided in the insulating glazing unit.

[ What is claimed is:] [1.] An automatic device for filling, with gases other than air, insulating glazing units constituted by two glass plates between which a spacer frame is interposed, said spacer frame being constituted by a hollow profile enclosing an inner region, said profile being sealed on lateral edges thereof to said glass plates so as to form an inner space, said device comprising:a station for conveying said two glass plates after coupling thereof to said spacer frame;at least one nozzle connectable to said spacer frame;an insert for joining and closing said spacer frame, said inner region of said hollow profile forming thus a manifold, said insert comprising at least two holes and a dividing wall interposed between said holes, said holes being located on a side of said insert that lies outside said inner space of said glazing unit for providing access from outside to said manifold;a coupling means for coupling said at least one nozzle to said holes for selectively injecting gas in, and expelling air from said inner space, said holes being further sealable automatically upon ending of the filling.
