ABSTRACT:
The inside lining of a folding box having inside lining (9), an opening area for extraction (100) in the box cutout (10) and a window opening area (106), which area is connected with the latter, in the inside lining is to be constructed in the form of a tube, that is, in such a way that it is closed in the longitudinal direction of the tube. In order to make this possible, a prefabricated foil tube, which lies flat, is to be provided with impressions for the window opening areas. In order that only the one side of the foil tube which has been laid flat is impressed, the foil tube is passed in a punching apparatus between an impressing cylinder and a countercylinder, between which a space is preserved by means of spacer rings. The space substantially corresponds to the thickness of the double-layer foil tube which lies flat. A punch cutting section, which is provided on the impressing cylinder, is to rise above the surface of the impressing cylinder only substantially up to a height which is equal to half of the width of the gap between the impressing cylinder and the countercylinder.
