Abstract
A guide roller for a printing press is designed to prevent foreign matters, such as ink or so forth from adhering on the peripheral surface thereof and to sweep up the peripheral surface by a traveling web. The guide roller comprises a roller body having a peripheral surface to contact with a traveling web. The roller body incorporates a first peripheral surface for converting the traveling speed of the web into a first rotational speed and a second peripheral surface having a different geometry to the first peripheral surface for converting the traveling speed of the web into a second rotational speed, the second peripheral surface being cooperative with the first peripheral surface for interacting the second rotational speed with the first rotational speed for determining a rotational speed of the guide roller so that the peripheral speed of the guide roller is differentiated from the traveling speed of the web.
