Important Remarks                                      
Bending capacies valid for multisteps bending method. Technical datas can be changed without notice . Reproducing and releasing without getting permission are prohibited.
Numbers in BLANK are theoretical capacity, (machine may not open wide enough to accept material and usually are not recomened.                        
The diameters (especially the tightest) are approximate and do not commit the manufacturer, as they are calculated on the machine power only.                        
The material spring back could in fact re-open the rolled cylinders to diameters larger than calculated, but out of the machine control, depending from the physical material spring-back.                  
The thinner is the plate and the more its spring back will re-open the rolled diameters. That’s why the thinnest stated capacities can more likely re-open to larger diameter than calculated (because of their higher spring back) even if tightly “wrapped” around the top roll.      
Thinner thicknesses than the minimum herewith stated, or harder materials may re-open more than the minimum diameter indicated because of their higher spring back.
