Vertical Plate rolling Machine
A special vertical plant for unwinding sheet metal from coils and bending medium-large diameters.
A machine designed for the production of silos starting from a coils, customizable with the cutting and welding system. It is not a simple vertical Plate Bending Machine, but a much more complete machine. It is in fact made with a coils feeding system ( motorized), with the pre-bending rolls (to eliminate the spring back return of the coils) and the asymmetrical plate roll to obtain the desired diameter. Furthermore, the rolls must to lead the sheet metal to the pinch rolls in the ideal position for the bending, even when the coils are almost exhausted.To make this possible, one of the rolls is mobile and at the output the sheet is supported by a horizontal orientable roller.
