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.
