It comprises a plurality of guide paths on which material webs originating from different printing units or individual strands of a material web are brought together and supplied to the folder or cutter in superimposed form. It is in itself z. B.
• the longitudinal folder device Since the location of such pages within a signature may vary from one print job to another, the longitudinal folder device must be able to process any of the webs fed to the overlay. In order to be able to supply different webs of material to a stationary longitudinal folding device, turning bars must be provided on the guide paths of these webs of material through the superstructure with which a material web is deflected away from the direct path through the superstructure the L jossfalz coupled through and then back between the other superstructure continuous material webs can be performed.
