Process and device of three-dimensional deformation of panels, in particular glass panels

Abstract

For improving a process of three-dimensional deformation of glass panes, said glass panes a) are heated up to the softening temperature in a first step b) are deformed in a second step, and c) are prestressed by means of targeted cooling in a third step, wherein the process steps are subsequently applied to individual successive treatment segments of the panel to be deformed in such a manner that different subsequent treatment segments of the panel are treated effectively in another process step at the same time, wherein subsequent treatment segments for example are heated up to the processing temperature, while preceding treatment segments for example are already deformed, wherein air flows are applied to the glass panes in at least one process step, the invention proposes that the air flows are combined of blown air and compressed air in a controlled manner.
