Publication number: 20180370836Abstract: Glass manufacturing apparatuses with cooling devices and methods for using the same are disclosed. In one embodiment, an apparatus for forming a glass web from molten glass includes an enclosure and pulling rolls that cooperate to draw a glass web in a draw direction rotatably positioned in an interior of the enclosure. A cooling device for extracting heat from the glass web is in fluid communication with a cooling fluid source and includes an actively cooled flapper disposed in the interior of the enclosure that is movable to facilitate varying the heat extraction. The actively cooled flapper serves as a heat sink in the interior of the enclosure and the cooling fluid extracts heat from the actively cooled flapper to remove heat from the glass web and the enclosure.Type: ApplicationFiled: November 18, 2016Publication date: December 27, 2018Inventors: Kenneth William Aniolek, Robert Delia, Bulent Kocatulum, Shawn Rachelle Markham, Steven Michael Milillo

Patent number: 9434632Abstract: A glass forming apparatus and method include a weir on at least a first side of a molten core glass reservoir. The weir includes an inclined surface that, in the intended direction of molten glass flow, slopes downward in the vertical direction while extending away from the molten core glass reservoir in the horizontal direction. A source of molten clad glass is configured above the glass forming apparatus such that when molten clad glass is flowing down and molten core glass is flowing over the weir, the molten clad glass drops onto the molten core glass at a highest upstream contact point that is located directly above the inclined surface of the weir.Type: GrantFiled: February 24, 2014Date of Patent: September 6, 2016Assignee: Corning IncorporatedInventors: Alexey Sergeyevich Amosov, Olus Naili Boratav, Frank Coppola, Vladislav Yuryevich Golyatin, Steven Michael Milillo, George Clinton Shay
