Abstract: During the transverse-folding operation of items of laundry, a number of layers are positioned one above the other so as to overlap one another. In order to achieve optimum folding quality, the aim is for layers of equal length to overlap, which is only rarely possible in practice. It is usually the case that the layers are of unequal length, and this gives rise to a difference in overlap. The invention makes provision for the difference in overlap to be eliminated, or at least to be minimized, in that it is determined whether a difference in overlap is present and the difference in overlap which may be established is corrected for the transverse-folding operation of the next-following item of laundry, which allows established differences in overlap to be compensated for automatically at least for the most part.

Abstract: The inventive method bases on a consequent realization of the following two conditions: firstly on the consequent separation of the “immaterial or virtual sphere” of information from the “material or real sphere” of the paper and secondly on the consequent standardization of the printed information to a form such that a further processing after printing is not necessary. The consequent separation between information (immaterial sphere) and paper (material sphere) leads to an irreversible combination of the two only in the location where and at the time when the printed information is delivered to the ordering end-customer (reader) in form of a commodity unit, i.e. when contents, location and time of such a commodity unit are defined by the ordering customer. The advantage is that information can be recorded and organized considerably faster and in particular can be copied and transported considerably more simply in the immaterial sphere than this is the case in material sphere.
