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.
