Abstract
For guiding webs of paper or cardboard, a guide cylinder extending across half of the web grips onto the surface of the web and achieves moving corrections on the webs by rotation or swinging. The long, linear support zone of the guide cylinder causes a high mechanical stress, whereby the guide cylinder exerts almost no corrective effect in its center zone. By dividing the guide cylinder into at least two spaced-apart, parallel guide rolls having their axes disposed perpendicular to the running direction of the material web, a suitable larger effective area is obtained for correction of the direction of movement.
