Patent number: 9896289Abstract: A method of automatically mounting a sheet from a cutting table onto a spacer frame of an insulating glass unit begins with identifying a position and orientation of a specified sheet on the cutting table and moving a robotic sheet pickup apparatus to a corresponding position to that identified for the sheet. An edge of the specified sheet is lifted off of the table, beginning with mechanical suction that brings a corner of the sheet to within proximity of a primary vacuum suction of the pickup apparatus. In particular, the pickup apparatus may have a substantially planar platen with a set of channels coupled to a vacuum source. Once the sheet is fully picked up by vacuum suction, the sheet is laid upon a top surface of a tilt table, which can be simply the platen inverted. The table (or platen) is tilted to bring a corner of the sheet to abut against physical fences. Once the position and orientation of the sheet is so known, the sheet is oriented to correspond to a frame, and attached thereto.Type: GrantFiled: January 13, 2014Date of Patent: February 20, 2018Assignee: Southwall Technologies Inc.Inventors: Vonn Sawatzky, Tom Engbersen, Christian H.

Publication number: 20150274584Abstract: The invention relates to an laminated glass for use in vehicles or in architecture, having a selective reflection of electromagnetic radiation from the wavelength spectrum of sunlight. According to the invention, an optical multi-layer system having a total solar transmission of TTS<40%, a transmission Tvis in the wavelength range of visible light >70% and a reflection Rvis in the wavelength range of visible light <12% is present on said laminated glass. For reflection upon vertical light incidence, it has a reflection colour according to ASTM 308 (illumination source D65 and standard observer 10°) within a colour space that is limited by the values Ra* from ?5 to 5 and Rb* from ?25 to ?40. Alone or in addition, the laminated glass has a reflection colour according to ASTM 308 for transmission and reflection upon verticle light incidence within a colour space (colour box) that is limited by the values Ra* from ?5 to 5 and Rb* from ?25 to ?40.Type: ApplicationFiled: December 13, 2012Publication date: October 1, 2015Applicant: SOUTHWALL TECHNOLOGIES INC.Inventors: Ronny Kleinhempel, Andre Karl-Heinz Wahl, Roland Claus Thielsch

Publication number: 20150239216Abstract: A method for laminating glass, a laminate assembly, and an adhesive-coated plastic material used in a laminate assembly. Specifically an adhesive, once applied to a plastic layer is grooved or textured to allow formerly trapped air to escape from between layers of a laminate assembly during a laminate process. This can allow for the adhesive layer to be thinner, while still providing for a final product that is relatively air bubble-free and optically pleasing or substantially free of optical defects caused by waviness of the plastic layer between two PVB sheets and/or wrinkles of the plastic sheet.Type: ApplicationFiled: May 11, 2015Publication date: August 27, 2015Applicant: SOUTHWALL TECHNOLOGIES, INC.Inventors: DAVID LEE HONEYCUTT, MATTHEW CODA, LEE CAMPBELL BOMAN, JULIUS G.

Patent number: 8728636Abstract: A low-e insulating glass unit has a suspended, coated IR reflecting polymer sheet under tension, e.g. from heat shrinkage. The polymer sheet is coated with a multilayer stack of dielectric and metallic layers, including at least one silver layer deposited upon a zinc oxide seed layer that is at most 15 nm thickness. The use of zinc oxide ensures good seeding for high quality silver layer growth, thereby providing low emissivity. The thinness of the zinc oxide ensures that it resists cracking when the polymer sheet is tensioned.Type: GrantFiled: May 28, 2013Date of Patent: May 20, 2014Assignee: Southwall Technologies Inc.Inventors: Ronny Kleinhempel, Julius G.
