Patent number: 9656910Abstract: Methods of forming a glass article are disclosed. In one embodiment, a method of forming a glass article includes translating a pulsed laser beam on a glass substrate sheet to form a laser damage region between a first surface and a second surface of the glass substrate sheet. The method further includes applying an etchant solution to the glass substrate sheet to remove a portion of the glass substrate sheet about the laser damage region. The method may further include strengthening the glass substrate sheet by an ion-exchange strengthening process, and coating the glass substrate sheet with an acid-resistant coating. Also disclosed are methods where the laser damage region has an initial geometry that changes to a desired geometry following the reforming of the glass substrate sheet such that the initial geometry of the laser damage region compensates for the bending of the glass substrate sheet.Type: GrantFiled: February 5, 2016Date of Patent: May 23, 2017Assignee: CORNING INCORPORATEDInventors: Brandon Allen Bazemore, Jeffrey Alan Decker, Jiangwei Feng, Diane Kimberlie Guilfoyle, Daniel Ralph Harvey, Yuhui Jin, Laurent Joubaud, Xavier Gerard Lafosse, Alexander Mikhailovich Streltsov, Ljerka Ukrainczyk

Patent number: 9611165Abstract: A method of bending a glass sheet includes placing the glass sheet on a support and heating the entire glass sheet to a first viscosity. A band of heat is applied and translated along the selected region of the glass sheet in which a predetermined is to be formed over a time period to form the predetermined in the selected region. The band of heat sectionally heats the selected region to a second viscosity that is lower than the first viscosity. An actuated force is applied to the glass sheet to incrementally form the predetermined bend in the selected region according to the location of the band of heat in the selected region.Type: GrantFiled: June 3, 2013Date of Patent: April 4, 2017Assignee: CORNING INCORPORATEDInventors: Thierry Luc Alain Dannoux, Paul Louis Florent Delautre, Patrick Jean Pierre Herve, Laurent Joubaud

Publication number: 20160368805Abstract: According to one embodiment, a method for forming a laminated glass sheet includes forming a multi-layer glass melt from a molten core glass and at least one molten cladding glass. The multi-layer glass melt has a width Wm, a melt thickness Tm and a core to cladding thickness ratio Tc:Tcl. The multi-layer glass melt is directed onto the surface of a molten metal bath contained in a float tank. The width Wm of the multi-layer glass melt is less than the width Wf of the float tank prior to the multi-layer glass melt entering the float tank. The multi-layer glass melt flows over the surface of the molten metal bath such that the width Wm of the multi-layer glass melt increases, the melt thickness Tm decreases, and the core to cladding thickness ratio Tc:Tclremains constant as the multi-layer glass melt solidifies into a laminated glass sheet.Type: ApplicationFiled: August 31, 2016Publication date: December 22, 2016Inventors: Antoine Gaston Denis Bisson, Olivier Fournel, Allen Mark Fredholm, Laurent Joubaud, Jean-Pierre Henri René Lereboullet, Xavier Tellier

Patent number: 9334187Abstract: A reformable area and a non-reformable area of a sheet of glass material are heated to a first temperature corresponding to a first viscosity. The reformable area is subsequently locally heated to a second temperature corresponding to a second viscosity, where the second viscosity is lower than the first viscosity. A bend is formed in the reformable area during the local heating of the reformable area by contacting a first pusher with the non-reformable area and translating the first pusher along a linear path to apply a pushing force to the non-reformable area that results in the bend in the reformable area or by contacting a second pusher with an edge area of the reformable area and rotating the pusher along a circular path to apply a pushing force to the edge area of the reformable area that results in the bend in the reformable area.Type: GrantFiled: August 15, 2014Date of Patent: May 10, 2016Assignee: CORNING INCORPORATEDInventors: Thierry Luc Alain Dannoux, Arnaud Dejean, Paul Louis Florent Delautre, Allan Mark Fredholm, Laurent Joubaud, Stephane Poissy
