  • Patent number: 5139552
    Abstract: A glass sheet such as an automobile window glass sheet is bent to shape and tempered at one stage by a sheet glass bending and tempering apparatus. The sheet glass bending and tempering apparatus has solid contact members for pressing a glass sheet, which has been heated nearly to its softening point, to a desired shape and depriving the glass sheet of heat to cool the glass sheet quickly, the solid contact means having a contact surface for contacting the glass sheet and depriving the glass heat of heat therethrough. The contact surface has a plurality of grooves defined therein, and a plurality of air outlet ports defined in each of the grooves, for applying cooling air to the glass sheet, and a plurality of air inlet ports defined in each of the grooves, for drawing the air applied to the glass sheet. When the opposite surfaces of the glass sheet are pressed by the solid contact members, the pressure is temporarily reduced and then increased again to cool the glass sheet.
