Claim 1
Independent Claim
324 words
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.
Claim 2
Independent Claim
324 words
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.
Claim 3
Dependent Claim
46 words
The method according to claim 1 in which said steps of 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 are performed by means of a pressurized fluid medium.
Claim 4
Dependent Claim
15 words
The method according to claim 2 in which said pressurized fluid medium is pressurized air.
Claim 5
Dependent Claim
50 words
The method according to claim 1 in which said steps of pressing the end region of said adhesive bead to the surface of said glass pane and pressing the two ends of said adhesive bead to the end of each other are performed by means of a pressurized fluid medium.
Claim 6
Dependent Claim
15 words
The method according to claim 4 in which said pressurized fluid medium is pressurized air.
Claim 7
Dependent Claim
68 words
The method according to claim 1 in which said first and second cutting operations are performed in an oblique angle with reference to the surface of said glass pane such that said initial portion of the extruded adhesive bead which has the desired final shape from which a portion not having the desired shape has been cut off is overlapped by said end region of said adhesive bead.
Claim 8
Dependent Claim
22 words
The method according to claim 1 in which the cutting operations are preformed by means of a jet of pressurized fluid medium.
Claim 9
Dependent Claim
15 words
The method according to claim 7 in which said pressurized fluid medium is pressurized air.
Claim 10
Dependent Claim
14 words
The method of claim 1 in which said glass pane is a vehicle pane.
