A device for correcting a deformation inside at least one material web in the machine direction of the at least one material web comprises at least one roller body seated rotatably about an axis of rotation for guiding the at least one material web, and at least one rigid shaft that is arranged in the interior of the roller body. The rigid shaft is divided in the direction of the axis of rotation axis into a first part and a second part, the first part and the second part each having at least one curvature. The first part and the second part are rotatable and/or pivotable independently of one another, so that the roller body can be adjusted between at least a first and a second external shape.
