ABSTRACT:
A method for regulating the internal tension of a web roll being wound between two underlying support rolls and an upper rider roll. During the whole winding process the distance between the centers of the support rolls is kept smaller than the sum of the distances from the center of the web roll to the centers of the support rolls. At the beginning, the support rolls are continuously moved farther away from each other and at a later phase of the winding process the supporting rolls are moved towards each other. The distance between the support rolls is preferably regulated so that the sum of the nip pressures provided by the support rolls and the rider roll is substantially constant.
