A corner connector for connecting two hollow-profile strips of an insulating glazing unit is presented. The corner connector includes a first plug-in leg, a second plug-in leg, a corner region, and a capillary tube with a first opening and a second opening. According to one aspect, the corner region connects the second plug-in leg to the first plug-in leg so to form angle between 45 and 180 between the two plug-in legs. According to another aspect, the first plug-in leg, the second plug-in leg, and the corner region are injection molded, and the capillary tube is integrally molded into the corner region. When installed, the capillary tube establishes a connection between the inner interpane space and corresponding surroundings of the insulating glazing unit.

A device for filling spacer frames with hollow-section strips has a storage tank for free-flowing, hygroscopic fill material, such as a molecular sieve. A line that leads to the spacer frame to be filled extends from the storage tank and empties into a fill opening in the wall of the spacer frame. The amount of the fill material poured into the spacer frame is determined by the amount of the fill material removed from the storage tank being detected. The amount of the fill material removed from the storage tank is detected by measuring the travel of a piston that rests with pressure on the fill material in the storage tank. The degree of filling is verified by the amount of the fill material removed from the storage tank being compared to the preset amount of the fill material that is to be poured into the spacer frame.

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.

A spacer, window assembly, method of manufacturing a window assembly, and method of manufacturing a spacer is described herein involving window assemblies having three sheets of material, which will be referred to as a triple pane assembly. Two interior spaces are defined within the window assembly: a first air space between the first sheet and intermediary sheet and a second air space between the second sheet and the intermediary sheet.

The present invention deals with integrating methods for manufacturing and applying a spacer frame to a glass plate, particularly in the circumstance of increased sizes thereof, of the rigid type, i.e. which profiles essentially are formed by a hollow body having cross section close to the rectangular, micro-perforated in the wall facing the chamber of the insulating glass, where at least the wall facing the outer cavity intended for the secondary sealant is made of solid metal material or with a metal liner, the remaining walls or all the walls being capable of being made of plastic or metal, e.g. aluminum or stainless steel. Certain innovative elements of the devices implementing such methods are also claimed.
