Our new line of 4-roll plate bending machines offer many decisive advantages. The four roll M line is the easiest to operate plate bending machine, thanks to its ability to pinch the plate between the 2 central driven rolls, prebend the leading edge, and rolling the body of the part along with the trailing edge all in one direction and in one pass. The plate is kept square, without slipping, during both pre-bending and rolling because of the constant clamping of the bottom and top rolls. This makes our four roll machine perfectly suited to be controlled by a NC or CNC control. The MG solution is reliable and effective. Side roll parallelism is maintained by a torsion bar system which connects both ends of the roll together.
