Abstract

Ein Verfahren zur Herstellung eines Rohres mit partiell unterschiedlichen Wandstärken ist so ausgebildet, daß in ein Ausgangsrohr ein mit mindestens einer außenseitigen, beidseitig in axialer Richtung begrenzten Vertiefung (7) versehener Dorn (6) eingeschoben, anschließend ein Ziehring (8), dessen lichter Durchmesser kleiner ist als der Außendurchmesser des Ausgangsrohres, über das gegenüber dem Dorn (6) in Ziehrichtung gehaltene Rohr (2) gezogen wird, wobei ein Teil des Rohres (2) in die Vertiefung (7) gedrückt wird und danach der Dorn (6) unter radialem Herausdrücken der in der Vertiefung (7) einliegenden Rohrwandung aus dem Rohr (2) herausgezogen wird.
