ABSTRACT:
The invention relates to a process for bending glass sheets. This process includes bending the glass sheet or sheets in at least two stages. The first stage employing the action of gravity leading to a shaped blank which is used in the formation of the final shape. The last stage which leads to the final shape, includes the simultaneous or nonsimultaneous, combined actions of gravity and at least one additional mechanical force. The invention also includes a bending apparatus providing at least one section including two separately useable parts with one of the parts being movable with respect to the other to permit the section to be arranged in one of two positions. In addition, the invention includes bent glazing having at least one docking angle exceeding 50.degree. and a radius of curvature below 200 mm.
