Abstract
A method for sealing insulating glass blanks (1), in which a sealing compound (3) is introduced from a sealing nozzle (7) into the outwardly open edge joint (2) of the insulating glass blank (1). A material tongue (15) of the sealing compound (3) emerging from the sealing nozzle (7) forms in front of the sealing nozzle (7). The size of the material tongue (15) is proportional to the amount of the sealing compound (3) introduced into the edge joint (2) per unit of time. Sealing is controlled in accordance with the length of the material tongue (15) detected by a sensor (10). In particular the amount of sealing compound (3) introduced per unit of time to the sealing nozzle (7) and/or the relative speed between the insulating glass blank (1) and the sealing nozzle (7) is controlled in accordance with the length of the material tongue (15) detected by the sensor (10).
