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.

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.

Sealants for insulated glass units or solar panels are disclosed. The sealant comprises polyisobutylene and a polymer which is a copolymer obtained from the polymerisation of at least one ethylenically-unsaturated aliphatic hydrocarbon monomer and at least one monomer containing a maleic anhydride moiety. The copolymer comprises at least one amphiphilic polymer side chain. Processes for producing the sealants for insulated glass units or solar panels are also disclosed. Insulted glass units and solar panels comprising the sealant are also disclosed. Processes for producing the insulated glass units and solar panels comprising the sealant are also disclosed.

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 glass panel unit includes: a first panel; a second panel facing the first panel; a sealing member bonded to respective facing peripheral portions of the first panel and the second panel; and at least one spacer provided in a reduced pressure space between the first panel and the second panel. The at least one spacer includes a resin body and at least one ultraviolet protective layer provided on a surface of the resin body.

An installation system to fabricate the multiple glazing units at the installation site is provided. The installation system includes a primary glazing unit, a secondary glazing unit, a spacer element, a primary sealant, a fixture, a secondary sealant and a dispenser. The installation system includes a fixture to apply the primary sealant on the spacer element. The installation system also includes a dispenser to apply the secondary sealant to a clearance between the primary glazing unit and the secondary glazing unit.

A window sealing system and method for use in sealing insulating glass units (IGUs) is disclosed herein. The system includes an articulating arm having a plurality of members and arms to allow movement about multiple axes defined by the articulating arm, and a sealant dispensing apparatus releasably couplable to the articulating arm. The sealant dispensing apparatus comprises a pivotable dispensing apparatus for dispensing sealant onto an IGU. The system further including a vision system, coupled to the sealant dispensing apparatus, for monitoring physical properties of the sealant during sealant application.

Various embodiments provide a method for applying a spacer to a planar substrate, comprising supplying the spacer to be adhered to the planar substrate; defining a first notch, a second notch, and a third notch in the spacer; applying an adhesive to the spacer; translating the spacer in a longitudinal direction; aligning a first end of the spacer with a first corner of the planar substrate; feeding the spacer and the planar substrate between a front carriage and a rear carriage along a longitudinal axis of an unadhered portion of the spacer while pressing the spacer against the planar substrate to adhere a portion of the spacer being pressed by the front carriage to the planar substrate, and rotating, with a six-axis robot, the planar sheet and adhered portion of spacer.

A conveyor belt for use in applying sealant to an elongated spacer frame and a method of use. The conveyor belt comprising a reversible belt rotatably attached to first and second pulleys. The reversible belt having a first perimeter length. The reversible belt is removably attached to the first and second pulleys. A first side and a second side of the replacement belt include first and second adhesive resistant materials. The first and second adhesive resistant materials are separated by an elastic support layer, wherein the first perimeter length is shorter than a second perimeter length measured about the rotation path of the first and second pulleys. The elastic support layer applies a force to first and second pulleys such that the reversible belt does not slip relative to the first and second pulleys.
