ABSTRACT:
In the production of packs with an outer wrapping of plastic film, a continuous forced guiding of a web of material (13) and the blanks (12) produced therefrom is important. The web of material (13) is fed to a knife roller (20). In the region thereof, the blanks (12) are produced by severing. The web of material (13) or each blank (12) is fed to upright suction belts (25, 26) via a transfer roller (39) with suction bores (42). The suction belts (25, 26) are movable up and down relative to the knife roller (20) and transfer roller (39) for carrying out a change of format.
