Method for producing multi-leaf printed products consisting of sheets folded inside each other

Abstract

A method with which multi-leaf printed products (50) are produced which printed products consist of a plurality of sheets folded inside each other. Especially if this kind of printed products are to be produced from a plurality of product parts, groups of loosely superimposed sheets or sheets loosely folded inside each other are to be manipulated. This manipulation is facilitated by producing intermediate products or product parts (30, 30') respectively which are easier to handle. They consist of an outer sheet (31, 31') with a first fold (34, 34') and of inner sheets (32) all sheets (31/32, 31'/32') being folded a second time in a second fold (33, 33') perpendicular to the first fold (34, 34'). The product parts (30, 30') are especially suitable for a further processing by collecting or inserting because they can be opened easily in the middle. The increased stability of the product parts in which the individual sheets hardly shift relative to each other also have advantages when collated. The first fold (34, 34') of the outer sheet (31, 31') or outer sheets are finally trimmed off.
