Abstract
Glass sheets which have been heated to bending temperature are bent by passing the glass sheets over a shaping bed having a substantially circular or substantially conical profile of revolution as seen in the longitudinal direction of the shaping bed. The shaping bed is composed of an assembly of revolving elements adapted for driving the glass sheets and at least one hot air cushion acting on the glass sheets in the first part of the bending zone.
