Disclosed are a method and device for sealing insulated glass blanks, wherein the insulated glass blank is moved substantially continuously through a sealing station. 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.

Methods for manufacturing insulating glass units (IGUs) include providing an unsealed IGU assembly that has first and second sheets of glass material and at least one spacer frame between the first and second sheets and sealed to at least one of the first and second sheets. The unsealed IGU assembly defines an interpane space and an IGU passage providing fluid communication between the interpane space and an environment external to the interpane space. In some cases the method includes positioning a filling device next to the IGU passage and introducing a gas into the interpane space through the IGU passage using the filling device. In some cases the method includes delivering a sealing material or sealing structure to the IGU passage with the filling device to seal the interpane space. Corresponding systems for manufacturing IGUs are also provided.

The present disclosure relates to a vacuum insulated glazing (VIG) unit and the method for producing such. Furthermore, the present disclosure relates to a window comprising a VIG unit enclosed in a frame.

A high speed parallel manufacturing line for manufacturing insulated glass units, the manufacturing line including a front conveyor system, a back conveyor system, a shuttle mechanism that distributes glass lites to the front conveyor system and the back conveyor system, an insulated glass unit spacer applicator having a spacer dispensing head configured to apply perimeter spacer material to one of the glass lites, the spacer head being proportionally movable relative to the glass lite as the glass lite is conveyed on the front conveyor mechanism to apply the perimeter spacer material to create a spacer applied lite and a gas press. A secondary edge sealing unit has a first secondary edge sealing head and a second secondary edge sealing head, each of the first secondary edge sealing head and the second secondary edge sealing head applying edge sealant to portion of a perimeter of an insulated glass unit.

When being sealed, insulating glass blanks (5) are held in a sealing station (2) gripped at the base by grippers (17) of a gripper arrangement (16) and/or by suction heads (15) and rest at the top against a roller beam (7) fitted with rollers (8). As the insulating glass blank (5) is sealed, only the nozzle (11) of a sealing assembly (10) moves along the outer edge of the insulating glass blank (5), which is stationary during the sealing process. When the lower edge of an insulating glass blank (5) is sealed, grippers (17) engaging the lower edge are released and move away downwards. Sealed insulating glass is removed from the sealing station (2) by a removal robot (24) onto the side opposite the sealing assembly (10), moved to a temporary store and placed therein on A-bearing supports (29) and fan frames (30) sorted according to production lots.

A heating station for use with, for example, a high speed parallel manufacturing line for manufacturing insulated glass units, the heating station including at least two opposing infrared heaters that linearly heat spacer material that includes integrated temperature sensitive adhesive. Each of multiple linear infrared heaters includes a respective associated temperature sensor. The infrared heater and temperature sensor are coupled to a spacer heating controller that controls intensity and/or duration of heating of the spacer material and adhesive to provide optimal wetting and adhesive qualities. Individual control of the at least two opposing linear infrared heaters compensates for variable environmental conditions affecting spacer material at different locations around and insulated glass unit.
