ABSTRACT:
Multi-sheet printed products are formed in that a multiplicity of zig-zag configured folded webs aligned with respect to one another are deposited upon one another. Each web is formed by individual sheets which are interconnected with one another at fold locations extending transversely with respect to the lengthwise direction of the web. For supporting the webs which are to be placed upon one another there is provided a drum containing radially protruding support ribs at its circumference. Initially, the first web is placed upon the support ribs such that each second fold location comes to bear upon a support rib. The first web guided in a spiral-shaped formation upon the drum arrives at an infeed portion or section of the next following web where the second web, in the same manner as the first web, is placed thereover onto the support ribs. Both of the superimposed webs are guided along a screw or helical-shaped path, if desired to further infeed or inlet portions and finally to a removal portion or section where the structure formed of the superimposed webs is removed from the drum. The finished multisheet printed products, which are formed by the superimposed bearing sheets of the individual webs and are still hanging at one another, are then separated from one another individually or in packages. Since the individual superimposed sheets remain interconnected with one another until formation of the finished printed product, the sheets need not be individually manipulated, rather can be handled in their composite formation.
