An apparatus and method for reversing a print material web is disclosed. A reversing bar unit includes a frame and a reversing bar pivotably mounted on the frame at a pivot point. The reversing bar includes an outer tube and an inner tube. A first end of the coupling element is coupled to the inner tube and a second end of the coupling element is moveably coupled to the frame at a distance from the pivot point. Upon a pivoting of the reversing bar the coupling element translationally or rotationally moves the inner tube relative to the outer tube.
