Tempering unit for a press bending machine of glass sheets

摘要

Quenching unit is equipped with tubes incorporating orifices to direct a cooling fluid at the glass sheet as it is conveyed through the unit by rollers. A quenching unit for a machine for pressing-bending glass sheets is equipped with tubes (5) feeding a cooling fluid close to a glass sheet (6) to be quenched. These tubes each extending globally in a direction parallel to the conveying direction (X-X') of the glass sheet. Each tube is provided with several orifices (56) for the ejection of the cooling fluid in the direction of the glass sheet to be quenched and with at least one notch (53) able to receive a roller (71) for conveying the glass sheet inside the quenching unit.
