A device for twisting a flat, fibrillated strip for producing artificial turf is disclosed. The device includes a hollow shaft having a central axis of rotation, a deflecting element that is mounted on the hollow shaft and that has a swing region, and a limiting element that is disposed on the hollow shaft. The hollow shaft allows the strip to be continuously passed through a hollow space of the hollow shaft. The deflecting element includes a swing pivot that is offset from the central axis. When the hollow shaft is rotated around its central axis, the swing region of the deflecting element is swung outward from the central axis to a swung-out position. As a result, the strip is rested against the swing region. When the deflecting element is in its swung-out position, the strip is rested against the limiting element that limits the outward deflection of the strip.
