Abstract

A device for corrugating a metal pipe having a corrugation extending transversely of its longitudinal direction. The device has a ring-shaped corrugating head drivable by a first electric motor and is rotatable about its axis in the operating position and a ring-shaped corrugation disc, coupled to the ring-shaped corrugating head, projects radially inwardly from the corrugation head. The corrugation disc is mounted in the corrugation head so as to be adjustable in the radial direction. A support, coupled to the corrugation head, is arranged so as to also be rotatable about the axis of the corrugation head. An adjusting mechanism acting on the corrugation disc is mounted on the corrugation head. The adjusting mechanism serves for radially adjusting the corrugation disc and is adjustable by the support. The support is connected to a second electric motor serving for rotating the support about the axis (A) of the corrugation head.
