ROUNDO 4-ROLL plate bending machines are ideal for plates thicknesses 1 – 25 mm and widths 500 – 8000. ROUNDO PASS machines are suitable machines for production of cylinders, ovals and square shaped objects. The 4-roll pinch design gives you the possibility to feed in the plate horizontally and gives you the better handle of the plate during the bending process. The working cycle of the machine is fast, smooth and easy thanks to the simple prebending and the possibility to roll the plate in one pass. Easy to integrate into a production line when equipped with automatic infeeding table of the plate, automatic ejection and down-line transport of the finished cylinder. CNC controls and a wide range of options are available for all models.

All ROUNDO 4-roll machines offer:

Hydraulic drive on top and lower rolls with infinitely variable speed control.
Hydraulic infinitely variable adjustment of the side rolls and lower roll.
Ensured parallelism of rolls even with maximum load.
Spherical roller bearings of highest quality for longer service life.
Hydraulically operated drop end.
