ABSTRACT:
In order to connect a new web (13), which is to be drawn off from a new bobbin (12), to a runoff web (10), drawn off from a runoff bobbin (11), of packaging material, a free end, namely an end piece (25), of the new web (13) is gripped by a drawing-off member (20) and drawn in one conveying cycle into the region of a connecting assembly (18). The runoff web (10) also runs through the connecting assembly (18). In the region of the connecting assembly (18), the two webs are laid against one another and are severed jointly by a cutter (41). After removing a web piece (45) of the runoff web (10), the web end (32), of the runoff web (10), and the web beginning (33) of the new web (13) are free. A connecting strip (47) can be brought to bear, from the free side, against the two webs.
