When sections of the edge joint of the insulated glass blank that are oriented transverse or oblique to the conveying direction are filled with sealing mass exiting from a filling nozzle, the filling nozzle is likewise moved in the conveying direction. When sealing mass is introduced from the filling nozzle into sections of the insulated glass blank that are parallel to the conveying direction, the filling nozzle is not moved in the conveying direction or is moved in the conveying direction at a velocity V2 deviating from the velocity V1 at which the insulated glass blank is moved. ## Claims ### Claim 1 Method for sealing insulating glass blanks (1) with at least one filling nozzle (7), from which sealing compound is introduced into the edge joint of the insulating glass blank (1), whereby the relative movements between the at least one filling nozzle (7) and the insulating glass blank (1) are created by moving the filling nozzle (7) and the insulating glass blank (1), wherein the insulating glass blank (1) is moved while sealing compound is being introduced into the edge joint from the at least one filling nozzle (7), and wherein the at least one filling nozzle (7) is moved in a direction that is parallel to the conveying direction (arrow 17), while sealing compound is being introduced into sections of the edge joint of the insulating glass blank (1) from the at least one filling nozzle (7). ### Claim 2 (depends on 1) Method according to claim 1, wherein the insulating glass blank (1), while it is being sealed, is moved continuously in one direction (conveying direction, arrow 17). ### Claim 3 (depends on 1) Method according to claim 1, wherein the at least one filling nozzle (7) during introduction of sealing compound into sections (11, 13) of the edge joint of the insulating glass blank (1), which are oriented parallel to the conveying direction (arrow 17), is stationary in the conveying direction (arrow 17) or is moved at a speed V2 that is different from the speed V1 of the movement of the insulating glass blank (1). ### Claim 4 (depends on 1) Method according to claim 1, wherein the at least one filling nozzle (7) during introduction of sealing compound into sections (3, 9) of the edge joint, oriented crosswise to the conveying direction (arrow 17), is moved at the same speed (V2) as the insulating glass blank (1) in the conveying direction and in addition crosswise (arrow 42) to the conveying direction (arrow 17). ### Claim 5 (depends on 1) Method according to claim 1, wherein the at least one filling nozzle (7), in addition to its movement parallel to the conveying direction (arrow 17), is moved crosswise (arrow 42) to the conveying direction (arrow 17) when filling compound is being introduced into sections of the edge joint, which sections form an angle in the conveying direction. ### Claim 6 (depends on 1) Method according to claim 1, wherein a single filling nozzle (7) is used, from which sealing compound is introduced in succession into all sections (13, 9, 11, 3) of the edge joint of an insulating glass blank (1). ### Claim 7 (depends on 1) Method according to claim 1, wherein two filling nozzles (7) are used. ### Claim 8 (depends on 1) Device for sealing insulating glass blanks with application of the method according to claim 1, with at least one filling nozzle (7), from which sealing compound is introduced into the edge joint of the insulating glass blank (1), and with a conveying system (25) for moving the insulating glass blank (1) during the sealing, wherein the at least one filling nozzle (7) can be moved parallel to the conveying direction (arrow 17) of the conveying system (25). ### Claim 9 (depends on 8) Device according to claim 8, wherein the conveying system (25) comprises a linear conveyor that clamps ono the lower edge of the insulating glass blank (1) and a roller beam (35) that is provided in the area of the upper edge of the insulating glass blank (1). ### Claim 10 (depends on 9) Device according to claim 9, wherein the linear conveyor comprises suction devices (27) and support elements (29), which can be moved together and synchronously in the conveying direction (arrow 17) of the insulating glass blank (1). ### Claim 11 (depends on 10) Device according to claim 10, wherein the suction devices (27) laterally clamp onto the surface of one glass pane (33) of the insulating glass blank (1) that faces the machine frame (23) of the device, and wherein the support elements (29) clamp from below onto the glass pane (31) of the insulating glass blank (1) that faces away from the machine frame (23) of the device (15). ### Claim 12 (depends on 10) Device according to claim 10, wherein the support elements (29) have a support head (30) and a bendable support arm (51). ### Claim 13 (depends on 10) Device

on 10) Device according to claim 10, wherein the suction devices (27) and the support elements (29) are guided onto a continuous, self-contained conveyor track (55). ### Claim 15 (depends on 8) Device according to claim 8, wherein the at least one filling nozzle (7) is arranged on a sealing head (19), which can be adjusted on a beam (5) crosswise (arrow 42) to the conveying direction (arrow 17), and wherein the beam (5), which carries the sealing head (19), can be moved parallel to the conveying direction (arrow 17) of the insulating glass blank (1). ### Claim 16 (depends on 2) Method according to claim 2, wherein the at least one filling nozzle during introduction of sealing compound into sections of the edge joint of the insulating glass blank, which are oriented parallel to the conveying direction, is stationary in the conveying direction or is moved at a speed V2 that is different from the speed V1 of the movement of the insulating glass blank. ### Claim 17 (depends on 2) Method according to claim 2, wherein the at least one filling nozzle during introduction of sealing compound into sections of the edge joint, oriented crosswise to the conveying direction, is moved at
