Rapid changes of the web tension take place at the roll change in the printing press. Variations in the machine direction depend on the tension control system and variation in the cross direction is strongly affected by paper and roll properties. The web tension profile can be measured with a single sensor scanning across the web or with a special beam equipped with several sensors. In this paper findings from the studies carried out with different tension measurement systems are presented. In the long-term study the effect of paper machine reel position as well as the changes within the roll and between the rolls on the web tension profile are underlined.
