An energy saving method for the bending of glass sheets is disclosed. A sheet of glass is heated in an oven, conveyed to a curving form which includes a plurality of arched rods for imparting a desired curvature to the glass sheet, and finally the curved glass is tempered. The glass is heated in the oven to a first temperature that is only about 10 DEG C. greater than the required temperature of the glass at the commencement of the tempering step. Heat loss from the glass between the steps of heating and tempering is minimized by the disclosed apparatus which comprises a thermally insulating enclosure as well as means for cooling the rods. |
