Abstract

The invention relates to a method and an arrangement for controlling the transverse variations in the tension of a web. In the method the transverse variation in the tension of the web is measured. On the basis of the result of the measurement of transverse variation in the tension of the web, an arrangement 11 is controlled, which acts on the transverse variation in the distance run by the web in such a way that the transverse variation in the tension of the web can be adjusted as required. <IMAGE>
