ABSTRACT:
A paper web that is being wound onto a rotating drum is severed so that it can be wound onto a second, empty drum. The paper web is severed with a tear strip that extends transversely to the paper web. A free end of the tear strip can be fastened to the empty drum, whereby the tear strip is wound helically on the empty drum and thereby severs the paper web. The free end of the tear strip is moved towards the empty drum with an apparatus that includes a carriage which is displaceably mounted towards the empty drum, laterally outside the drum and transversely in relation to the drum axis. A suction device for holding the tear strip is disposed on the carriage. The suction device is controlled by a vacuum source with which it communicates through a suction line.
