Abstract:
A rotary folding device, rotatable in a rotation direction around an axis, comprising at least one folding mandrel (10), positioned on an outer periphery of said folding device, for the manufacture of an essentially cuboid package made of at least one foldable blank (17), the folding mandrel (10) having thin walls, namely a large-surface front wall (13) and a large-surface rear wall (12) as well as two opposing narrow side walls (14, 15), for bearing corresponding walls of the package, and said blank having portions (23, 24) which overlap one another in a region of one of the two narrow side walls (15) and which are connected there to one another by gluing, wherein the narrow side wall (15) that bears the overlapping blank portions (23, 24) has a narrower width (B.sub.15) than the opposite narrow side wall (14), so that the folding mandrel (10), in order to achieve an almost exactly rectangular cross-section of the finished package, itself has a trapezoidshaped cross-section.
