Pillar delivery films for vacuum insulated glass units. The delivery films include a support film or pocket tape, a sacrificial material on the support film, and a plurality of pillars. The pillars are at least partially embedded in the sacrificial material or formed within sacrificial material molds, and the sacrificial material is capable of being removed while leaving the pillars substantially intact. In order to make an insulated glass unit, the delivery films are laminated to a receptor such as a glass pane, and the support film and sacrificial material are removed to leave the pillars remaining on the glass.

An assembly and method of drawing differing types of sheet stock through one or more assembly stations to make a spacer frame that is used in an insulating glass unit is disclosed. The assembly and method include fabrication of a spacer frame having a recess formation in a portion of a peripheral wall of a connecting structure that allows two ends of the spacer frame to form a lateral connection. The assembly and method further include feeding along a process axis formed by a path of travel of the material an elongated length of sheet stock into a feeder press and a roll former, both having translating rollers that move transversely to the process axis to accommodate different materials used in the sheet stock. The assembly and method also include a swaging assembly for forming a recess formation in a portion of the peripheral wall of the spacer frame.

The present invention relates to a method for manufacturing vacuum insulating glass, the method involving applying a vacuum sealant to a first surface of a first glass sheet, the vacuum sealant including a plastic film having a preferably rough surface, placing a second glass sheet on the vacuum sealant such that a cavity is formed between the first and second glass sheets and the vacuum sealant, applying a vacuum to an outer surface of the vacuum sealant until a vacuum is formed in the cavity, wherein the first and second glass sheets are placed in a vacuum bag to apply the vacuum, and heating the vacuum sealant while the first and second glass sheets are in the vacuum bag.
