In an arrangement for forming rolls from a running web, the web is slit in its longitudinal direction and wound into a plurality of rolls, all having the same rotation direction during winding. The arrangement comprises means providing a peripheral as well as a central roll support force acting on the rolls during winding. The arrangement is so dimensioned that, due to the increase of the roll diameter during winding, the ratio of the peripheral support force and the central support force of a roll undergoes a substantial change merely as a result of the geometrical construction features of the arrangement. In the final phase of the winding of a roll, the central support force of the roll is considerably higher than the peripheral support force of the roll. |
