摘要:
A method and device for bending superposed sheets of glass. The sheets are picked up by a top form furnished with a suction creating an upward airflow blowing over the rim of the sheets, the suction being sufficient to lift and hold the superposed sheets against the top form, then the sheets are pressed between the top form and a full surface solid concave bottom form furnished with openings, the pressing beginning conducted while the suction is not yet finished or is finishing, then the superposed sheets are formed, by suction of the main face of the bottom sheet through the openings of the bottom concave mold, the forming by suction beginning while the pressing is not yet finished, and then the sheets are cooled. Windshields free of optical defects may thus be produced.
