ABSTRACT:
A paper web guide device for guiding and conveying a paper web comprises a plurality of guide rollers arranged in a parallel configuration in a printing system. The guide rollers comprise a mix of driving guide rollers equipped with a driving mechanism and braking guide rollers equipped with a braking mechanism. The driving guide rollers are controlled so as to make the revolving speed of the guide rollers faster than the travelling speed of the paper web. The braking guide rollers are controlled so as to make the revolving speed of the guide rollers slower than the travelling speed of the paper web. This guide device can exactly perform a cleaning operation on the guide rollers within a short period and without accumulating the tension applied to the travelling paper web.
