Description

In paper mills, the speed of paper web has been increasing all the time and the speeds may be in excess of 120 km/h (60–70 miles/h). High speeds are also needed in slitter-winders to manage the continuous production of paper from the machine despite the roll changes. It is clear that at such speeds the tension of the moving paper has to be known; in particular, the tension profile across the machine direction since the profile may contain tension peaks that break the web even though the average tension may be acceptable.
