The invention relates to a method of manufacturing a curved automobile glass pane. The glass sheet heated in a continuous roller conveyor furnace to bending temperature, is picked up by a traveling suction device and transported to a curving station adjoining the furnace. In the curving station the glass sheet is deposited onto a curving device which is comprised of a curving-form frame and a curving form which form occupies the interior space of the frame. The suction device is withdrawn, and a hot gas stream is applied from above, which stream impinges on the glass sheet, whereby said sheet is forced against the curving device comprised of the curving-form frame and interior curving form. Then the glass sheet is lifted from the interior curving from by means of the curving-form frame which frame now serves as a support ring, and sheet is transported to the neighboring cooling station.
