This machine is used to post-bend the straight ends of the longitudinal
edges of open-seam pipes (max. 40 mm wall thickness) step by step.
Heavier thicknesses are pre-bent on the pre-bending press.
It is no longer necessary to use roller-type machines, which damage the
root face and crush the edges of an open-seam pipe.
Depending on the tooling, pipes with gap widths of approx.
50 to 120 mm can be post-bent.
