Abstract (en)
[origin: EP2752256A1] The device has a corrugation unit (2) that is rotated in a working position to a circumferential direction for forming a projection. A guide bush (5) is provided for guiding the movement of a smooth pipe (1) positioned in front of the corrugation unit to a longitudinal direction. A supporting sleeve (7) is arranged behind the corrugation unit, and tightly surrounds a ring-shaped corrugated pipe (6) in a withdrawal direction of the corrugated unit without affecting the movement in the longitudinal direction.
