    • A system for maintaining calender rolls of a paper machine clean when producing high-gloss paper or coated paper, such as LWC or MWC. To prevent a coating agent, such as coating dye, from adhering onto and soiling a smooth surface of a calender roll, with an overheating phenomenon, the system has a second measurement station (10) provided with measuring and indicator means for producing an output indicating soiledness of the web (W) or a humidity profile. When the output of the second measurement station (10) indicates excessive soiledness or an uneven humidity profile, the system performs at least one of: cleaning the surface of the smooth-surfaced calender roll; changing the nip load in the calender (5); making a correction adjustment of the CD-directional humidity profile of the web (W); cutting the web (W) and conducting it into the pulper; and/or changing the running speed of the web (W).

    • In the method for paper web transfer in a paper machine or finishing apparatus for paper, a paper web (W) is transferred in a first machine portion (A) at a first travelling speed. In a second machine portion (B) following the first one in the travel direction of the web, the tail is transferred at a travelling speed lower than the first travelling speed. In the second machine portion (B) the tail (TB) is transferred independently without a draw connection to the web (W, TA) transferred in the first machine portion (A), the travelling speed of the tail (TA) transferred in the second machine portion (B) is increased, and a draw connection is established between the tail and the web (W, TA) transferred in the first machine portion.
