ABSTRACT:
A supply stream (1) of flat articles (8), in particular of printed products that are conveyed hanging and held by grippers, is transformed into an imbricated stream (2, 3, 4, 5) or into sections of an imbricated stream, in which the articles are arranged in one of two or advantageously four possible ways. For the stream transformation, the articles (8) are selectively deposited on a conveying surface at a first or at a second depositing point (I, II). The articles (8) deposited at the first depositing point (I) or to be deposited at the first depositing point (I) are additionally rotated by 180° (after or before deposition) and the held article edges are, advantageously selectively, leading or trailing on deposition. The selective stream transformation and switching between transformation modes (A, B/B′, C or D/D′) are very simple. The stream transformation is suitable for supplying an imbricated stream of printed products selectively to either one of two stacking devices with opposing stacking directions, and for producing cross stacks (6, 7) in the stacking devices.
