Abstract (en)
[origin: EP1340558A1] The deforming tool has a pusher element (21) in the inner arc wall region of the curved blank. At the beginning of the deformation of the inner arc wall region, it provides a counter-force. During the deformation, it is withdrawn from this region so that the inner arc wall region is pressed out towards the withdrawing pusher element.
