Abstract
To readily open up a multi-sheet folded printed product comprising at least two folded printed sheets or signatures which are placed one inside the other, there is provided an innermost printed sheet which is of greater length at the center in the direction of the fold line than the remaining printed sheets. The innermost printed sheet thus protrudes past the remaining printed sheets by a marginal section or lap at one lateral edge. An opening device now can engage the protruding marginal section and can open up the printed product at the center without difficulties. When the printed product has been completed, i.e. after insertion of an enclosure or inserts into the opened printed product, the marginal section or lap is cut away. Since such marginal section or lap must be cut away only at one printed sheet the loss in material associated with the cutting operation is exceedingly small.
