ABSTRACT:
In a method for the corrugating of metal tubes in which a smooth tube, preferably a longitudinally seam welded smooth tube is passed continuously through a bushing and acted on immediately behind the bushing by a corrugating tool, in which tool a corrugator disk having a larger inside opening than the diameter of the smooth tube is mounted for free rotation eccentrically in a corrugator head which can be driven in rotation, and the corrugated tube is deflected from the direction of manufacture in the direction towards the place of action of the corrugator disk in order to obtain a deeper corrugation.
