  • Patent number: 6425227
    Abstract: The invention relates to a method and apparatus for the handling of individual flat articles coming out of a production machine (3). The articles may be particularly letter envelopes, which are assembled and, if needed further processed and packaged. The core of the invention resides in that initially a plurality of flat articles or letter envelopes (2, 2a) are lifted as partial stacks (8, 8a) and then are deposited at another location, and in that the partial stacks, during lifting and/or depositing (rearranging), are moved in such a way that the flat articles or letter envelopes (2, 2a) are standing, following the deposition, on the same side or edge (b) as originally or on another side or edge (a).
