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.

A nozzle pair (3, 6) is used to coat the side faces of spacers (1) for insulating glass with an adhesive material, the adhesive material being applied to the side face of the spacers (1) through the nozzles (15) of the nozzle pair. As the side faces of the spacer (1) are coated with adhesive material the nozzle pair (3, 6) is moved along the sides of the spacer (1), the relative movement between the nozzle pair (3, 6) and the spacer (1) being obtained by a movement of the spacer (1) and/or the nozzle pair (3, 6). With this way of working, there is no need to rotate the spacer (1) about an axis perpendicular to its plane and therefore the rotation can be dispensed with.

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.

The present invention relate to a method to produce an insulating glass unit (IGU) comprising the following steps: Forming a first assembly by fastening to a first glass plate (3) an IGU spacer (1) and, apart from said IGU spacer (1), an edge element (2) comprising at least one through hole (10), said edge element (2) being fastened with the help of one of an immediate tack and green strength adhesive (5) or a compressible adhesive seal (8); Fastening by pressing a second glass plate (6) to said first assembly, said second glass plate (6) being fastened to the IGU spacer (1) and to the edge element (2), said edge element (2) being fastened thanks to the other one of an immediate tack and green strength adhesive (5) or a compressible adhesive seal (8); Injecting a structural sealant (9) into said at least one through hole (10) of said edge element (2) to fill up the space between the IGU spacer (1) and the edge element (2).

A spacer includes a polymeric hollow profile, including a first and second side wall, a glazing interior wall connecting the side walls to one another; an outer wall arranged parallel to the glazing interior wall and connects the side walls to one another; a cavity surrounded by the side walls, the glazing interior wall, and the outer wall, a moisture barrier on the first side wall, the outer wall, and the second side wall, wherein the moisture barrier includes a multi-layer system having a barrier function including a polymeric layer and an inorganic barrier layer, a metallic or ceramic outer adhesive layer having a thickness of less than 100 nm, a binding layer between the adhesive layer and the multi-layer system and including a polymer selected from oriented propylene, oriented polyethylene terephthalate, biaxially oriented propylene, and biaxially oriented polyethylene terephthalate. The binding layer is directly adjacent the adhesive layer.

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.
