The invention relates to a method and device for cambering superimposed glass sheets. The inventive method consists in picking up the sheets by a top mould provided with a suction means producing an upwardly directed airflow which passes over the sheet edges, wherein said suction is sufficient for lifting and holding the superimposed sheets by said top mould, in pressing the sheets between the top mould and an entire lower concave mould provided with holes in such a way that the pressing is started when the suction of a previous step is not yet finished or near to be finished, in shaping the superimposed sheets by sucking the main surface of a lower sheet through the holes of a lower concave mould in such a way that the forming by suction is started when the pressing is not yet finished and in cooling the sheets. Said invention makes it possible to produce optical defect-free windscreens
