  • Patent number: 6254713
    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 lay

  • Patent number: 6085451
    Abstract: The present invention relates to an information carrier with an upper and a lower cover layer and a plate, which can be moved between the cover layers. The information carrier contains information, which is given a defined association by the appropriate positioning of the plate with respect to the cover layer. In order to be able to produce the information carrier in a more compact and simpler way, it is designed in accordance with the present invention in such a way that the plate (10) is embodied to have a circular disk shape, except for at least one cut off edge section, and can be viewed and manually moved through a cutout in at least one of the cover layers, and is formed out of a center layer arranged between the upper and the lower cover layer by cutting a separating slit in the shape of an arc of a circle.
