  • Method and device for producing hard packs for cigarettes
    Patent number: 7134257
    Abstract: For producing hard packs, namely hinge-lid boxes or shell and slide packs in particular, inner and outer pack units are prepared separately in each case, namely a shell (20), on the one hand, and a blank for a hinge-lid box, on the other hand. The inner pack unit, comprising a cigarette block (10) and a further pack part, namely a slide (13) or a collar, is prepared in the region of a mandrel turret (24). The pack units are then brought together, with continued rotary movement, by axial displacement relative to one another.
