Abstract: Method for the operation of packaging machines and packaging machine. In packaging machines for the manufacture of cigarette packs (10) in particular, interruptions in operation are often unavoidable, in order to change the type of pack, but also, for example, on account of the end of a workshift. In the case of interruptions in operation of this kind, the packaging machine is emptied. For this purpose, members and assemblies are coordinated with one another and controlled in such a way that, after the operating phase "emptying" has been initiated, a last pack content, in particular a cigarette group (11) is identified and is transferred completely through the packaging machine. After this cigarette group (11) has passed through individual members, the latter are switched off, in particular a tin foil assembly (20), a paper assembly (23) and a revenue-seal appliance (29) in the region of a drying turret (26).
