  • the stop element is displaceable by means of the adjustable lever in the axial direction of the rotor and can thereby press the sealing element against a side wall of the circumferential groove. Due to the tension of the sealing element with the side wall of the circumferential groove, the sealing element is temporarily - for the bending process of the metal strip - fixed, so that in Circumferentially acting force for bending the sheet metal strip causes no corresponding displacement of the sealing element.
