ABSTRACT:
For the production of soft-cup cigarette packs, use is made of folding mandrels (13) which are designed as hollow bodies, on the outside of which pack blanks (12) are folded, and into which a cigarette group (11) is pushed. To produce a precise pack, the folding mandrel (13) preferably consists of two mandrel parts (19, 20) which are connected to one another by thin laser-weld seams (21, 22). The two mandrel parts are made of spring-steel sheets. The folding mandrel (13) so designed is releasably fastened to a folding turret in a special way via a connecting piece.
