ABSTRACT:
A multiplicity of web guide rollers in a printing machine incorporate motors therein provided with respective reduction units and each reduction unit is provided on the side of an output shaft with a mechanism such as a clutch, so that the rollers can rotate normally, reversely or idly. When the web guide roller is cleaned, the roller is rotated in a direction opposite to the running direction of the web, whereby the contamination on the surface of the roller is wiped off by the web. Since the rotating directions of the respective rollers are selected by the controller in association with running paths of webs, so that automatic cleaning of the web guide rollers can be effectively performed.
