Abstract:
A method for producing a plurality of composite layered information carriers having: an upper cover layer; a lower cover layer; and a center intermediate layer, each defining a longitudinal direction, the center intermediate layer 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; and a recess or a transparent section in one of the cover layers, wherein pieces of information are provided with a defined association by an appropriate positioning of the sliding tongue with respect to the cover layers, and can be viewed through the recess or transparent section, the method comprising the steps of:making available sheets constituting the upper and lower cover layers and a sheet constituting the center intermediate layer, the sheets having at least one of a length and width which is a multiple of the length, or respectively the width, of the information carrier to be produced;cutting a plurality of separating slits in the center intermediate layer to extend one behind the other in the longitudinal direction, to be aligned with each other and to be separated by a nonslit portion between which aligned slits form several parallel rows;forming a composite layered arrangement of the upper cover layer, the lower cover layer and the center intermediate layer with the cut plurality of separating slits, using for this purpose markings provided on the sheets as positioning aids in the course of forming the composite layered arrangement and connecting the layers outside of the separating slits, forming a matrix arrangement of information carriers; andcutting the composite layered arrangement transversely to the longitudinal direction and such as to intersect the separating slits forming thereby as many information carriers as there are in the matrix arrangement, each including a sliding tongue formed in the center intermediate layer.
