ABSTRACT:
The invention relates to an apparatus for the heat-sealing of surfaces of articles, in particular for the sealing of closing flaps of a wrapper of a cuboid pack, in conjunction with a packaging machine, the packs being conveyed one above the other or side by side and transversely movable sealing jaws being provided which can be moved cyclically towards the surfaces to be sealed. Especially, the invention relates to the processing of cigarette packs. On the one hand, this can concern the outer wrapper of such a pack, consisting of regenerated cellulose film or of another heat-weldable packaging material. However, the cigarette pack concerned can also consist entirely of a (multi-ply) sealable film.
