Method of mechanically applying a profiled adhesive bead to the surface of a glass pane

A method of mechanically applying a profiled adhesive bead to the surface of a glass pane along the edge thereof, the method comprising the steps of:

• extruding an adhesive bead through a profiled extruding nozzle;
• starting the operation of leading said extruding nozzle along the edge of said glass pane by means of a robot and depositing the extruded adhesive bead along the edge of said glass pane;
• simultaneously mechanically cutting off that portion of the extruded adhesive bead which lies in the region of the start point of said extruding nozzle and which does not have the desired final shape from that portion of the extruded adhesive bead which has the desired final shape by means of a first cutting operation performed in a direction transverse to the extension of the adhesive bead;
• mechanically releasing and removing said cut off portion of the adhesive bead which does not have the desired final shape from the surface of said glass pane;
• taking off said extruding nozzle from the surface of said glass pane as soon as it has reached the point where said portion of the extruded adhesive bead which lies in the region of the start point of said extruding nozzle and which does not have the desired final shape had been cut off from that portion of the extruded adhesive bead which has the desired final shape;
• mechanically cutting off the profiled adhesive band extruded by said extruding nozzle to such a length that two free ends of the adhesive bead are formed which ends congruently touch each other by means of a second cutting operation preformed in a direction transverse to the extension of the adhesive bead and running parallel to the direction of said first cutting operation;
• and
• mechanically pressing the end region of the adhesive bead to the surface of said glass pane and mechanically pressing the two ends of the adhesive bead to the end of each other.
