Patent number: 9394193Abstract: An apparatus for drawing a glass ribbon including an edge roll assembly that contacts the glass ribbon with a force that is dynamically altered by an actuator electrically coupled to a sensor that measures the force applied against the ribbon. Dynamic, or real-time, variation of the edge roll force minimizes stress variability in the glass ribbon and improves ribbon shape control.Type: GrantFiled: August 9, 2013Date of Patent: July 19, 2016Assignee: CORNING INCORPORATEDInventors: James Gary Anderson, Lewis Kirk Klingensmith, James Paul Peris, David John Ulrich

Patent number: 9061932Abstract: A pull roll apparatus and method are described herein that can control a cross-draw tension and a down-draw tension of a glass sheet while manufacturing the glass sheet. In one embodiment, the pull roll apparatus includes a first driven stub roll pair, a second driven stub roll pair and a control device (e.g., PLC) that controls the first and second driven stub roll pairs while a first edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the first driven stub roll pair and while an opposing second edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the second driven stub roll pair. If desired, the pull roll apparatus may include a pulling roll assembly (located below the first and second driven stub rolls) or another set of driven stub roll pairs (located below the first and second driven stub roll pairs).Type: GrantFiled: November 25, 2013Date of Patent: June 23, 2015Assignee: Corning IncorporatedInventors: James Gary Anderson, Liam Ruan de Paor, Lewis Kirk Klingensmith, Patrick Aaron Parks, George Clinton Shay, Michael George Shultz, David John Ulrich

Patent number: 7685841Abstract: In the formation of sheet glass by the overflow downdraw process, the width of usable sheet glass is maximized by downwardly flowing edge portions of the sheet over web-like members and thereafter over extensions which intersect with and are downwardly inclined relative to the web-like members to thin edge portions of the glass flow and maintain sheet width. The extension members are preferably removably attached to the web-like members, greatly facilitating replacement of the more easily damaged extension members.Type: GrantFiled: June 26, 2008Date of Patent: March 30, 2010Assignee: Corning IncorporatedInventors: Olus Naili Boratav, Steven Roy Burdette, David John Ulrich
