Abstract

During the production of cigarette packs having an inner wrapper of thin packaging material, the blank (10) of the inner wrapper is provided with impressed lines, namely transverse impressed lines (19, 20) which delimit a base wall (11) which is first contacted by a cigarette group (23) when the latter is wrapped in a U-shaped manner. By virtue of the impressed lines (19, 20), the mechanical load forces exerted on the cigarette group during the U-shaped folding process is reduced. Furthermore, a cigarette conveyor (25) for transferring the cigarette groups (23) is driven in a non-uniform manner, i.e. at reduced speed, when receiving a blank (10), and at a correspondingly greater speed during other conveying operations.
