Abstract: The pack-forming unit (12) brings printing products into a tube-like form and sheathes them with a retaining element. The packs (20) thus formed are ejected into a first stack compartment (22) which is emptied into a second stack compartment (24) as soon as a certain number of packs (20) are stacked in it. A strap (30) is then laid around the stacked packs (20), in order to keep the latter together to form a bundle (32) which can be easily handled.

Abstract: The printing product (16) is inserted from above into a compartment (52) and between two pairs of fingers (56), and is positioned such that it is arranged approximately symmetrically with respect to the axis of rotation (54') of the fingers (56). Upon rotation of the fingers, the printing product is folded by interaction with flexible belts (114, 116) in an S-shaped form and is thus brought into a tube-like configuration. A film-like retaining element (34) is wound up along with the printing product (16), in order to sheath the printing product (16) and maintain it in the tube-like configuration.
