ABSTRACT:
An apparatus for closing openings in prefabricated, flexible spacer strips arranged between the glass sheets of insulating glass elements (5) comprises a nozzle (11) for the dispensing of sealing compound. The nozzle (11) has an extension (21) introducible into the opening to be sealed, this extension being gradually pulled out of the opening again during introduction of the sealing compound. For this purpose, the nozzle (11) is mounted to be movable at least in the direction of its nozzle orifice (arrow 19). The nozzle (11) is mounted, for example, on a holder (13, 40, 16) to the frame of the apparatus to be pivotable about an essentially perpendicular axis (17). The holder (13) of the nozzle (11) can be shifted forwards and backwards (arrow 15) transversely to the plane of the support for the insulating glass elements (5), in order to be able to vacate the conveying path of the insulating glass elements.
