Abstract
A method for pneumatic forming of foil workpieces includes the steps of positioning a foil workpiece between a first and a second forming element, the second forming element having at least one forming cavity, moving the first and second forming elements into a clamping relationship with the foil workpiece, increasing pneumatic pressure between the first forming element and the foil workpiece to form the foil workpiece into the forming cavity, supplying a gas between the foil and the second forming element sufficient to enable the foil workpiece to move along the surface of the second forming element during the forming of the foil workpiece into the forming cavity, and removing the foil workpiece in a formed condition from between the first and second forming elements.
