Abstract
A method and a device for compensating and equalizing the tension forces across the width of a moving web makes use of a tension compensation roll, which is pivotably supported, and rotatable around a pivotal axis. In the presence of a difference in the tension force across the width of the moving web, the tension compensation roll is pivoted via gears with teeth to an extent such that the tension forces in both halves of the web are equalized.
