Abstract (en)
[origin: US4694714A] To change reels (11, 12) of packaging material in or on packaging machines, a front region of a connecting sheet (13) is held ready in an exact relative position in a common conveyor track (18). When the end of a run-off sheet (10) is reached, an end piece of the latter is severed, so that the run-off end and the front end of the sheets of material (10, 13) can be conveyed (further) in an exact position to one another.
