The upper and lower straightening rollers 15, 16 are disposed such that they form a straightening gap 17 between an inlet 6 and an outlet 7 of the straightening machine 1 to act from above and from below on the metal strip or metal part 10 to be straightened and to guide the latter through the straightening machine 1. The straightening rollers are provided with coupling elements 5, disposed on an end side, for coupling drive shafts of a drive device 2, 3, 4, and are removable from the respective roller mill 12, 14. At least some of the straightening rollers 15, 16 are provided with coupling elements 5 at in each case both ends sides, so as to be able to reverse the straightening rollers 15, 16 within the roller mill 12, 14.
