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.

A device for severing a paper web wound on a first drum, and for initiating the winding of the paper web on a second, empty drum, comprising:
- a guide rail extending substantially transversely to a traveling paper web, a carriage movably guided along said guide rail, and a holding device disposed in said carriage;
- a tear strip for severing the paper web, a supply of said tear strip mounted on one side of said paper web, said tear strip having an end adapted to be held by said holding device in said carriage and being movable by said carriage along said guide rail from the one side of the paper web to another side thereof;
- and
- wherein, prior to severing the paper web, said tear strip is moved to extend along said guide rail from the one side of the paper web to the other side thereof and wherein, for severing the paper web, said tear strip is wound on the second drum starting from the other side of the paper web and to the one side thereof, such that the paper web is severed and transferred to the second drum.
