Publication number: 20200062634Abstract: Methods and apparatus provide for: conveying a glass web from a source toward a destination in a transport direction; scoring the glass web in a width direction thereof to product a score line having a plurality of separated score segments, thereby defining a section of the glass web between the score line and leading edge of the glass web; supporting the glass web such that an increasing portion of the section of the glass web becomes cantilevered as the glass web is conveyed such that the portion of the section of the glass web is sufficiently large to generate stress in the respective score segments and drive respective cracks through the thickness of the glass web; and permitting the section of the glass web to separate from the glass web along the score line.Type: ApplicationFiled: October 29, 2019Publication date: February 27, 2020Inventors: Robertson Dewhurst BOOTH, Douglas Edward BRACKLEY, Michael Vincent FICARRA, Andrew Peter KITTLESON, Gautam Narendra KUDVA, Eric Lee MILLER, Ian David Tracy

Patent number: 10570047Abstract: A method of continuously processing glass ribbon having a thickness ?0.3 mm. The method includes providing a glass processing apparatus having a first processing zone, a second processing zone and a third processing zone. The glass ribbon is continuously fed from the first processing zone, through the second processing zone to the third processing zone. The feed rate of the glass ribbon is controlled through each processing zone using a global control device. A first buffer zone is provided between the first processing zone and the second processing zone in which the glass substrate is supported in a first catenary between two, spaced-apart, payoff positions. A second buffer zone is provided between the second processing zone and the third processing zone in which the glass substrate is supported in a second catenary between two, spaced-apart, payoff positions.Type: GrantFiled: July 7, 2015Date of Patent: February 25, 2020Assignee: Corning IncorporatedInventors: Tomohiro Aburada, Jeffrey Robert Amadon, Douglas Edward Brackley, Gautam Narendra Kudva, Gary Edward Merz, Eric Lee Miller, Michael Yoshiya Nishimoto, Ian David Tracy, Matthew Daniel Trosa, Rui Zhang

Publication number: 20180141847Abstract: A method of continuous processing of flexible glass ribbon having a thickness of no more than 0.35 mm using a glass processing apparatus is provided. The method includes providing the glass processing apparatus having at least three processing zones including a first processing zone, a second processing zone and a third processing zone. The flexible glass ribbon is continuously fed from the first processing zone, through the second processing zone to the third processing zone. Rate of the flexible glass ribbon is controlled through each of the first processing zone, second processing zone and third processing zone using a global control device. The second processing zone has a conveyance path for the flexible glass ribbon through a cutting zone having a radius of curvature of from about 100 inches to about 400 inches.Type: ApplicationFiled: May 17, 2016Publication date: May 24, 2018Inventors: Robertson Dewhurst Booth, Douglas Edward Brackley, Scott Winfield Deming, Andrew Peter Kittleson, Gautam Narendra Kudva, Dale Charles Marshall, Gary Edward Merz, Eric Lee Miller, Kathleen Elizabeth Morse, Ian David Tracy

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

Publication number: 20150321948Abstract: A process and system for applying coating materials to glass edges of various profiles. The glass edge is coated by picking up the coating material from an applicator such as, for example, a roller, through precise independent or relative control of the spatial relationship between the edge of the glass article and the applicator to achieve desirable product attributes such as coating thickness, profile, coverage areas and consistency. Such spatial relationships include the gap distance between the roller and applicator, coating thickness on the applicator, applicator and/or glass speed, and the like.Type: ApplicationFiled: November 21, 2013Publication date: November 12, 2015Inventors: Donald Orrin Bigelow, Thomas Charles Coller, Scott Winfield Deming, Curtis Robert Fekety, Mark Stephen Friske, Gregory William Keyes, Hongkyu Kim, Hideki Masaki, Michael George Schultz, Ian David Tracy
