Abstract: A straightening machine for straightening a metal strip or planar metal parts is provided, having a number of upper straightening rollers 15 which are each mounted at one first and one second bearing location 24, 25 in an upper roller mill 12, and a number of lower straightening rollers 16 are each mounted at one first and one second bearing location 24, 25 in a lower roller mill 14. 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.

Abstract: A straightener for straightening a metal strip and/or flat metal parts, having a number of lower straightening rolls which are mounted in a lower roll frame and a number of upper straightening rolls which are mounted in an upper roll frame. Stay bolts connect the upper and lower roll frame at a preselectable spacing, the stay bolts being assigned adjusting apparatuses for changing an effective length of the stay bolts, which effective length defines the preselectable spacing, and for compensating for changes in the effective length during operation. The adjusting apparatuses include a mechanically movable sliding wedge which changes the effective length of the stay bolts.
