  • Adaptation of glass shaping means for tempering flat glass
    Patent number: 4111676
    Abstract: A continuous operation for heating, bending and tempering glass sheets is converted to tempering flat glass sheets by employing a heat-reflecting shield over the glass path in the unused bending zone. In the quenching zone, quenching medium is directed against the underside of the glass sheets with greater force than is customary, and driven hold-down rolls are employed above the glass path in the quench zone in order to maintain movement of the glass sheets through the quenching zone.
