Abstract (en)
The object of the invention is to allow adaptation to different sizes and final shapes of tube without changing the rollers in a device for the continuous forming of a metallic tube (9) with the aid of forming rollers (3) which enclose the tube and lie opposite one another in pairs relative to the axis of the tube. To achieve this object, it is proposed that the forming rollers (3), which are adjustable radially relative to the tube (9), each be mounted to allow them to be pivoted parallel to the axis of the tube about a pivoting axis (14) which passes through the region of the centre (12) of curvature of the associated rolling-contour section or is at a distance therefrom in the direction of the roller axis (15). <IMAGE>

Um bei einer Vorrichtung zum kontinuierlichen Umformen eines metallischen Rohres (9) mit Hilfe von das Rohr umschließenden, einander bezüglich der Rohrachse paarweise gegenüberliegenden Formrollen (3), eine Anpassung an unterschiedliche Rohrgrößen und Rohrendformen ohne Rollenwechsel vornehmen zu können, wird vorgeschlagen, daß die radial gegenüber dem Rohr (9) verstellbaren Formrollen (3) je um eine zur Rohrachse parallele Schwenkachse (14) schwenkverstellbar gelagert sind, die durch den Bereich des Krümmungsmittelpunktes (12) des zugehörigen Walzkonturabschnittes geht oder davon einen Abstand in Richtung der Rollenachse (15) aufweist. <IMAGE>
