Patent number: 9919381Abstract: A method for cutting a flexible glass ribbon includes directing the flexible glass ribbon to a flexible glass cutting apparatus including a laser. The flexible glass ribbon includes a first broad surface and a second broad surface that extend between a first edge and a second edge of the flexible glass ribbon. A laser beam is directed from the laser onto a region of the flexible glass ribbon. A crack is formed through the flexible glass ribbon using the laser beam. The crack is propagated along the flexible glass ribbon using the laser beam and a local mechanical deformation in the flexible glass ribbon.Type: GrantFiled: January 28, 2014Date of Patent: March 20, 2018Assignee: Corning IncorporatedInventors: Anatoli Anatolyevich Abramov, Chester Hann Huei Chang, Todd Benson Fleming, Eric Lee Miller, Ian David Tracy

Patent number: 9822028Abstract: Methods of processing a glass ribbon are provided. The method includes the step of traversing the glass ribbon through a travel path at a predetermined velocity and severing the glass ribbon to create an upstream web and a downstream web. The method further includes the step of increasing a relative velocity of a downstream edge portion with respect to an upstream edge portion to create a gap between an upstream severed edge and a downstream severed edge. In other example methods, a segment of the glass ribbon is removed to create a gap between an upstream severed edge and a downstream severed edge. In still further example methods, an upstream severed edge is directed along a second travel path to create a gap between the upstream severed edge and a downstream severed edge.Type: GrantFiled: July 21, 2015Date of Patent: November 21, 2017Assignee: Corning IncorporatedInventors: Chester Hann Huei Chang, Todd Benson Fleming, Dale Charles Marshall, Gary Edward Merz, Christopher Michael Rhoads, John Earl Tosch, Thaddeus Francis Trzeciak
