ABSTRACT:
In a deep drawing method, a sheet metal blank is positioned between two dies of a deep drawing machine and then shaped into a hollow article, whereby the dies, at least during a partial stroke phase, undergo a controlled non-rectilinear relative movement and one of the dies is shifted by a transverse displacement mechanism in a direction transversely to a stroke direction.
