Abstract: 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.

Abstract: An apparatus and method for precision bending a glass sheet that includes an oven for heating the glass sheet to a temperature near the softening temperature of the glass sheet. A stage for supporting the glass sheet. A pair of reference surfaces on the stage for precisely locating the glass sheet on the stage. At least one bending mechanism on a pair of arms inside the oven for bending an edge portion of the glass sheet. Inward facing first stop surfaces on the arms that contact reference surfaces on the stage for precisely locating the bending mechanism on the arms relative to the stage and the glass sheet.

Abstract: 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.
