Abstract
Guide rollers in a web-fed rotary printing press are cleaned by a web of material that is provided with signal information, such as a bar code or a punch code. The retrievable signal information is used by one or more signal reading devices that are used to apply cleaning agent to the web and to create a speed differential between the guide roller and the material web.
