Abstract
The invention relates to a deep-drawing method and a corresponding deep-drawing device. The deep-drawing device has at least two projections () and at least two corresponding lamellar gaps () in a die (), the width and positioning (Pi) of the lamellar gaps () being adjustable. Folding of a metal sheet () is brought about by closing the lamellar gaps (). During the subsequent deep-drawing process, the projections () are lowered into corresponding recesses (). Flat metal sheets () as well as previously corrugated metal sheets () can be folded and deep drawn by means of the deep-drawing device and the deep-drawing method.
