An air-floating transfer apparatus for manufacturing insulated glazing units (IGUs). The apparatus includes a frame arranged at a certain angle on one side of a conveyor belt, a support for the frame, and an air pump supplying air to the frame. The frame comprises multiple rows of air blowers that expel air towards one surface of the glass being transported by the operation of the air pump, and between these multiple rows of air blowers, there are arranged multiple rows of exhaust support plates with exhaust holes formed at regular intervals to selectively exhaust air discharged from the air blowers. Additionally, the device includes an opening and closing unit that opens or closes the exhaust holes of the exhaust support plates depending on the thickness of the glass being transported.

A system that can travel and rotate and is designed in the manner of an at least one-armed robot is used for handling spacer frames in the course of the production of insulating glass. The system grasps a spacer frame with a gripper system provided to rotate at the free end of the robot arm. A spacer frame is moved by the system to stations of a line for producing insulating glass. For example, a spacer frame is held in a station for producing spacer frames, moved to a station for filling the spacer frame, when the spacer frame is to be filled with hygroscopic material, then further moved to a station, in which the lateral surfaces of the spacer frame are coated with sealing and adhesive agents, and finally moved to a station for assembling insulating glass, in which the spacer frame is mounted on a glass panel.

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.

A corner connector for hollow-profile spacers of insulating glazing units is presented. The corner connector includes first and second legs, connected via a corner region, that include respective leg inner sides, leg outer sides, end faces, and a plurality of side faces. According to one aspect, the leg inner sides, the leg outer sides, and/or the side faces include at least one retaining element; the leg inner sides provide respective inner bearing faces having: inner regions adjacent the corner region, and outer regions adjacent the inner regions and the end faces. The inner bearing face of at least one of the leg inner sides has, in its inner region, a positive gradient starting from the corner region in the direction of its end face.

A process for the construction and application of a rigid spacer frame for insulating glass involves preparing segments of the rigid spacer frame, applying a butyl sealant to sides of the segments facing in use glass sheets, storing the segments at a warehouse, assembling the segments to form the rigid spacer frame at an apparatus for the construction and application of the spacer frame, the apparatus having a support movable in vertical direction between a lowered assembly start position and a raised assembly end position and arranged with references for the segments. The process further involves positioning the movable support at a height so as to allow positioning of the rigid spacer frame at a surface of a glass sheet arranged on a support surface of the apparatus, and positioning the rigid spacer frame at the surface of the glass sheet.

Insulating glazing unit containing at least one spacer for the spacing of glass panes received in a frame, wherein a barrier film is applied to the spacer, at least on the side directed towards the frame. The barrier film is a composite film, which, on the side directed towards the spacer, has an adhesive or sealing layer as the internal layer and, on the side directed towards the frame, a barrier layer containing oriented EVOH and a thin adhesive layer of metal or metal oxide located on the outside and directed towards the frame.

The technology disclosed herein generally relate to assembly equipment for window units. In one embodiment, a window unit assembly system is taught that has a frame component that is configured to support equipment for a window unit assembly line. A pane conveyor is supported by the frame component and is configured to move panes along the window unit assembly line. A spacer conveyor is supported by the same frame component as the pane conveyor and is configured to move spacer elements along the window unit assembly line.

A device for delivering a sealant material includes a first nozzle having a first nozzle head and a second nozzle having a second nozzle head. The first and second nozzle heads each independently have an outlet, an inlet opposite the outlet, and an open channel that extends through a body of the nozzle heads from the inlet to the outlet. The first nozzle is spaced apart from the second nozzle to form a space between the nozzle heads to allow a component to enter a first side of the device and exit a second side of the device while passing by the first and second nozzle heads. A notch is formed through the body of each of the first and second nozzle heads at a side where the component exits the device to distribute a sealant material onto each side of the component.
