Abstract
A method for bending glass sheets is disclosed in which a heated glass sheet (12) is introduced between spaced upper and lower bending platens (16,18). Heat source (19), integral with platen (18), is operable for applying heat in close proximity to the glass sheet (12) between the platens (16,18) to maintain an optimal bending temperature and the glass sheet (12) is bent such that a specific geometric orientation of the bend on the glass sheet (12) is controllable and repeatedly reproducible during a production operation.
