This Four-Rolls Bending Machine is characterized by high security in the bending process. Generated by the clamping pressure between the lower and upper roll the bending plate is backed up constantly, especially in the rather complex pre-bending process. The symmetrical arrangement of the side rollers, make the pre bending possible from both sides without changing the sheet. The normal bending process is as with the three roll bending machines by the pitching of the side roll to create the appropriate radius.
It’s surely the right machines for large productions.
