How to Level Plates in Two Directions

[FH]

I need to know about a process for leveling and blanking a plate with thickness of about 1.5 mm.
We use plates in roll-forming for outer body of buses. Unfortunately the plates we use are not flat in both directions.
Does anybody know about some references or mechanisms to solve the a.m. problem?

You need a roller leveler that can do shape control also. These are used by steel processing houses on the coil before shearing it into sheets. It may be very difficult to find someone who can roll cut sheet to straighten it. If you are not dealing in steel, you might be able to find someone to give it a try, since to level sheet it has to be worked past the yield point by inter meshing rolls.


good luck.
