ABSTRACT:
A strip of wrapping material is fed and cut into leaves by a unit comprising first and second contrarotating rollers equipped with respective first and second blades of which the first blades operate as a pair to cut the strip transversely into leaves, and the second blades operate as a pair to impress a transverse line on each leaf, this line combining with a longitudinal line, impressed by a further disc cutter, to create a “pull” portion removable from the leaf by tearing. The timing of the second blades can be controlled, so as to adjust the position of the transverse tear-off line on the leaf, by components interacting with the strip along a predetermined feed path extending between two decoiling rollers and a cutting zone that coincides with the line of substantially tangential proximity between the two cutter rollers.
