Title: Method for producing a composite-like information carrier

Abstract: A method for producing a composite layer-like information carrier with an upper and a lower cover layer (6) and a center intermediate layer (6), having two parallel separating slits extending through it in the longitudinal direction, so that a sliding tongue is formed, which can be moved in the longitudinal direction, wherein the information can be viewed through a transparent section in the cover layer; in order to execute the method efficiently, it comprises the following method steps: making available sheets constituting the upper and the lower cover layer and of a sheet constituting the intermediate layer, cutting a plurality of separating slits, which extend one behind the other in the longitudinal direction, and are aligned with each other and are separated by a strip, in several parallel rows, in the intermediate layer, layered arrangement and connection of the sheets in areas outside of the parallel separating slits, each of which delimits a respective sliding tongue, and cutting the composite layer structure formed in this way in such a way, that the cut, which delimits an information carrier transversely in respect to the longitudinal direction (8) respectively intersects the separating slits of the latter, so that the connection of the sliding tongue to the sheet constituting the intermediate layer is severed.
