Publication number: 20170327401Abstract: A roll forming apparatus includes at least one forming roll being spaced from a forming body to define a gap. The forming roll includes a working zone portion having a working zone surface with a length extending along a rotation axis of the forming roll and a thermal resistance boundary extending at an acute angle relative to the rotation axis. In further examples, methods include the step of feeding a stream of molten glass through the gap to form a glass ribbon including a formed thickness.

Publication number: 20170247279Abstract: The present invention is directed to methods for making high quality glass tubes, and apparatuses for making high quality glass tubes. Because glass tubes made using the methods and apparatuses disclosed herein are substantially free from the optical defect known as paneling, the glass tubes may be used in displays for consumer electronic devices. The glass tubes are made by a continuous process in which a flow of molten glass is provided on an inner surface of a hollow, rotating mandrel such that the glass coats the inner surface of the mandrel and flows downstream on the inner surface of the mandrel, during which it is cooled to provide a higher viscosity. The glass is then removed from the mandrel and drawn to obtain a glass tube. A flow of molten glass may also be provided on the outer surface of the mandrel and joined with the glass flow on the inner surface of the mandrel when the glass flows exit the mandrel.Type: ApplicationFiled: September 9, 2015Publication date: August 31, 2017Inventors: Antoine Gaston Denis Bisson, Allan Mark Fredholm, Laurent Joubaud

Patent number: 9458044Abstract: According to one embodiment, a method for forming a laminated glass sheet includes forming a multi-layer glass melt (300) from a molten core glass (106) and at least one molten cladding glass (126). The multi-layer glass melt (300) has a width Wm, a melt thickness Tm and a core to cladding thickness ratio TC:TCl. The multi-layer glass melt (300) is directed onto the surface of a molten metal bath (162) contained in a float tank (160). The width Wm of the multi-layer glass melt (300) is less than the width Wf of the float tank (160) prior to the multi-layer glass melt (300) entering the float tank (160). The multilayer glass melt (300) flows over the surface of the molten metal bath (162) such that the width Wm of the multi-layer glass melt (300) increases, the melt thickness Tm decreases, and the core to cladding thickness ratio TC:TCl remains constant as the multi-layer glass melt (300) solidifies into a laminated glass sheet. The invention also relates to the associated apparatus.Type: GrantFiled: July 13, 2012Date of Patent: October 4, 2016Assignee: Corning IncorporatedInventors: Antoine Gaston Denis Bisson, Olivier Fournel, Allan 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
