Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Embodiment examples of the invention are hereinafter described in more detail with reference to the attached FIGURE.

(2) FIG. 1 in principle shows the procedure of folding a foil according to the invention with reference to a two-step folding for manufacturing a data carrier. Although, a single-step or multi-step folding is also possible.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

(3) FIG. 1 in principle shows the procedure of folding a foil 2 according to the invention with reference to a two-stage folding. A foil 2 is transported in the direction of machine operation 4 during the method. The foil 2 here has three regions 6, 8 and 10. Each of the regions 6 and 10 has several gaps 12 and 14 which were punched into the foil 2. The gaps 12 and 14 serve for the formation of a gap, into which a module, e.g. a chip module, is inserted. The regions 6 and 8 are coated with adhesive. Before the foil 2 is folded according to the invention, two scored lines 16 and 18 are scored into the foil 2 to facilitate the subsequent folding. First, the region 10 is folded in the direction 20 along the scored line 18, so that the region 10 comes to lie in precise fit on the region 8 coated with adhesive and is bonded thereto. The resulting region 22 is two-ply and has the gaps 14 at its surface. Next, the region 6 is folded in the direction 24 along the scored line 16 in precise fit onto the region 22 and bonded thereto. The result is now a three-ply foil in the region 26. The regions 6, 8 and 10 were folded in precise fit onto each other and bonded together, so that, for example, the gaps 12 and 14 have come to lie exactly one above the other. Tensions in the resulting card cancel each other out by an odd-numbered folding, e.g. single or triple folding in the method according to the invention. The orientations possibly present in the at least one foil cancel each other out by folding according to the invention. A resulting bulge or a distortion of the product is avoided thereby. In addition to the method described above it is possible to introduce in precise fit and to also bond a further foil during the folding. Therefore, constructions made of several foil layers and adhesive layers are realizable. This is interesting in particular when gaps in different planes, independent of the material thickness of a foil, are necessary. At the end of the method at least one data carrier, e.g. a SIM card or a credit card is punched out from the at least one folded and bonded foil. Alternatively to the punching, any other suitable method can be used for separating data carriers from the folded and bonded foil, e.g. separating by means of laser or water jet.

(4) According to the invention, during the above-described procedure of folding at least one foil 2 at least one security element is arranged on at least one outer side and/or in the interior of the data carrier to be manufactured. For reasons of clarity, a representation of a security element in FIG. 1 has been omitted.

(5) The security element is supplied to the procedure described above from a roll or as bulk material.

(6) The security element is supplied such that it is incorporated into an area 6, 8 of the foil 2, which is coated with adhesive.

(7) Alternatively, the security element may be embossed into at least one foil 2 of the data carrier.

(8) The security element may effect a chemical, optical or haptic reaction when used.

(9) As a security feature which effects a chemical reaction there may be used, for example, a scented lacquer, a color indicator, a catalyst or a test strip.

(10) As a security feature which effects an optical reaction there may be used, for example, a self-luminous ink, a security thread, champs or metal pigments.

(11) As a security feature which effects a haptic reaction with a user of the data carrier there can be used, for example, a logo or a Braille character.
