ABSTRACT:
A paper web which is being wound on a first drum is severed and the winding of the paper web on a second, empty drum is simultaneously initiated. The paper web is severed with a cord, such as a tear strip or the like, whose free end can be moved from the one side of the paper web to its other side. The free end of the tear strip is moved along a guide rail located below the paper web and aligned transversely to it. In the process, a carriage is guided along the guide rail, which is equipped with a holding device for the tear strip. The tear strip is then fastened on the empty drum, whereupon it is spirally wound thereon. The paper web is thus severed and transferred to the empty drum.
