Verfahren und Vorrichtung zum Herstellen eines Hohlprofils mit Abschnitten unterschiedlicher Wandstärke

The method involves fixing one and another section of a hollow profile (1) at spaced holding positions and forming a compression limiting space, where one and another holding positions in succession are moved, so that a compressing section of the tubular hollow profiles is compressed into the compression limiting space. The tubular hollow profile is arranged between the holding positions. The compressing section of the hollow profile acts with an oscillation when moving the holding positions in succession. An independent claim is included for a device for manufacturing a hollow profile, particularly a pipe, with sections of different wall thickness.
