VERFAHREN UND VORRICHTUNG ZUM HERSTELLEN VON (ZIGARETTEN-)PACKUNGEN

摘要

In the production of packs made of (thin) cardboard such as cigarette packs, complex folding processes may cause problems when blank portions are moved to the proper pack position, especially when blank portions are "too long" for the folding process. To remove this problem, the respective blank portion is, during the folding process, temporarily deformed in a way which shortens its effective length, i.e. curved in an arched manner. In the production of hinge lid packs having a collar (11) attached to a front wall (12) thereof in a single piece, this blank portion is, while being folded from an upright to a horizontal position, temporarily curved by a folding lever (58) applying pressure until the blank portion reaches the horizontal folding position.
