Abstract
A gravity bending mould for bending glass panes, includes a frame-like support surface that is suitable for arranging a glass pane thereon and that has an outer edge and an inner edge, wherein the support surface has an outer region facing the outer edge, an inner region facing the inner edge, and a central region between the outer region and the inner region, and wherein the outer region is planar and horizontal, the central region is inclined toward the inner edge and is planar or curved, and the inner region has a curvature in the opposite direction to the curvature of the glass pane, and wherein the inner region is more strongly curved than the central region.
