These roll bending machines are especially suitable for use on building sites and in training workshops due to their robust construction, easy handling and low weight.

They are driven by a handcrank directly on the bottom shaft. The working shafts are arranged asymmetrically, spherically turned, and are held in place by maintenance-free dry plain bearings. The clutch gears are to the left, so that even narrow pipes can be easily pulled off.

The top shaft can be swung out one-handed toward the front and is locked by a closed blocking bearing. The bottom and back shafts can be adjusted from the right, outer side of the machine. The bottom shaft advances via handle and hand levers, the back shaft advances via ratchet lever and tooth segment.

The settings can be easily reproduced via the sensitive tooth segment. The back shaft can be tilted for conical rounding.
