Description

Method for producing an eruptible data carrier

The present invention describes a process for the preparation of a

Disk, wherein the disk is broken out of a carrier. The data carrier itself is stamped in its original geometric format so that, if necessary, the data carrier can be broken out of the original format in a smaller format. The disk is

for example, a SIM card that has the ID-000 format in the original format. From the ID-000 format, e.g. As a smaller format, the mini-UICC format will be broken out.

From the prior art it is known that SIM cards are punched in ID-000 format from a carrier in the ID-1 format, the SIM cards are punched only to the extent that they still with at least one bridge with the Carriers are connected. To disconnect the SIM card from the carrier, the bridge is broken by pushing the SIM card out of the carrier.

Depending on the application, at least one notch is inserted in the SIM card to make the SIM card in a smaller format, e.g. Mini UICC format to break out of the larger ID-000 format. If the smaller format is broken, then the larger format remains e.g. as a frame left over.

A disadvantage of the prior art is that for punching out the data carrier, e.g. in ID-000 format, from the carrier, e.g. the ID-1 format has, so the

Disk is connected to the carrier only by means of at least one web, a ring punch is necessary. For introducing the at least one notch, a further punch is necessary, with a smaller score for each smaller format, which is punched as a notch in the disk, a separate Kerbstanzwerkzeug is necessary.

In addition, the at least one web which connects the data carrier and the carrier must be notched in at least one further working step, which lengthens a production time accordingly. The acquisition and

Maintenance costs are for the ring punching tool and for the at least one Kerbstanzwerkzeug, which are specific tools for the respective disk according to the geometries and formats used, very high. Consequently, the delivery times of the tools also amount to several weeks, eg the delivery time for a tool is between six to eight weeks.

Another disadvantage of the prior art is that if the volume is smaller in size, e.g. Mini UICC format, again as a larger format medium, e.g. ID-000 format is to be used, then it is not possible in the prior art to use the smaller format of the disk back into the larger format from which the smaller format was broken out, and continue to use the volume in the larger format, because the smaller format is no longer with the larger format without tools, such as an adhesive, permanently connect.

It is therefore an object of the present invention to provide a solution to the problems described above. In particular, it is an object of the invention to provide a solution with which a disk is punched in a format from a carrier, so that the costs and delivery times for production and tools are significantly reduced and in addition to the format of the disk breakable from the Carrier is punched to punch at least a smaller size, so that the volume can be broken out of a larger format than a smaller size, but the smaller format can be used again in the larger format so that the volume can be used again in the larger format , wherein the disk in smaller format without the use of excipients, such as an adhesive, permanently and releasably connected to the larger format.

This object is achieved by a method according to the invention for producing a data carrier, the data carrier having a first geometric shape, wherein the data carrier having the first geometric shape is produced from a carrier by the carrier in at least one region along the first geometric shape of the data carrier is removed, for example by means of punching, lasers or mill, so that the disk remains connected to the carrier by means of at least one web, wherein the data carrier with the first geometric shape breakable by breaking the at least one web from the carrier, wherein the method is characterized in that within the first geometric shape of the data carrier at least one smaller, second geometric shape of the data carrier is punched, so that the data carrier with the smaller, second form from the larger, first form ausbrechbar, the disk with the smaller, second form after breaking out of the larger, first form back in the larger, first shape can be used to be used as a larger first form media after the larger, first form from the carrier

was broken out. The advantage of the invention is that the method the

Manufacture of a data carrier whose geometric shape or

Dimensions can be adjusted as required by a user of the data carrier. It is the user even possible to break the disk in the required geometric shape or dimension either from the carrier or from a larger form of the disk in a currently required form and reinsert the smaller form back into the larger form of the disk to the disk in the larger size, without the use of additional adjuvants, such as adhesives, to produce a permanent and releasable bond between a smaller size that has been used in a larger format. Thus, the user himself can easily adapt the geometric shape or the format of the data carrier to changing shapes or dimensions and enlarge or reduce the shape or dimensions of the data carrier. The first, larger shape is similar to a frame within which the second, smaller shape is located. If the volume in a smaller format is broken out to a larger size, then the larger size usually remains as a frame. For manufacturers of data carriers has the advantage that only a disk is prepared, which is prepared for use in several possible shapes or dimensions, without having to make their own data carrier for each shape or dimension, which saves a great deal of time and money. An advantageous exemplary embodiment of the invention is that at least a third geometric shape of the data carrier is punched into the data carrier within the second geometric shape of the data carrier, wherein the third shape is smaller than the second shape, wherein the third shape can be broken out of the second shape, in order to use the data carrier in the third form, wherein the data carrier in the third form can be inserted into the second form after the break-out in order to use the data carrier in the second geometric shape after the larger second mold has broken out of the first mold was achieved, with a releasable but permanent connection without the use of auxiliaries, such as an adhesive, between the second and the third form. The advantage is that any number of smaller geometric shapes or dimensions of the data carrier can be made, with the individual shapes or dimensions differ only by their dimensions and that a small form can be broken out of a large mold, but again the small Form can be used in the large mold, in such a way that the small form in the larger form used are so firmly connected to each other that the disk can be used in the larger form.

Another advantageous embodiment of the invention is that

overlap at least a small geometric and at least one larger geometric shape of the disk. This has the advantage that different geometric shapes of data carriers can be realized.

Another advantageous embodiment of the invention is that the

at least one bridge is punched from an upper and / or a lower side.

The advantage is that by punching from both sides of a defined material remains left, which defines a force that is necessary to break the disk out of the carrier.

Another advantageous embodiment of the invention is that at least the second form is punched from the top and / or bottom in the disk. The advantage, as mentioned above, is that a defined material thickness remains, which defines a force necessary to break the data carrier with a small shape out of a large mold. The larger form remains, for example, in the form of a frame left. At the same time, this two-sided punching enables the smaller mold to be re-inserted into the larger mold, so that the smaller mold can be detachably connected to the larger mold and the data carrier in the larger mold can be used further

Compound no auxiliaries, such. an adhesive, are necessary. Another advantageous embodiment of the invention is that only to a certain depth is punched without the disk completely

penetrate, so advantageously after stamping a defined

Material thickness remains, the material thickness defines a force that is necessary to break the disk with the first geometric shape of the carrier and / or a smaller geometric shape of the disk of a larger, geometric shape.

A further advantageous embodiment of the invention is that at least one geometric shape of the data carrier is punched by means of at least one stamping sheet. The advantage of the stamped sheet is that a stamped sheet having a desired stamping geometry can be produced within a few days at low cost in comparison with complicated stamping tools known in the prior art. The change between different punching plates is possible in a few minutes, which requires several hours in the stamping tools used in the prior art. With punching plates in particular circumferential and / or partial notches can be punched. An integration of a punching plate into existing tools and punching machines is possible without any problems. In addition, with punching plates it is possible to produce a geometry, eg an ID-000 format or a mini-UICC format, in one work step. For this purpose, two punching plates are used according to the invention, wherein a first punching sheet from above and a second punching sheet from below simultaneously punch a desired geometry in the data carrier. Another advantage of the stamping sheet is that in contrast to Prior art, the stamping sheet does not have to be matched to the material to be punched. Another advantage of the invention is that in punching plates

punched out material from the stamped sheet or the punching geometry of the punching plate must not be ejected or ejected.

A further advantageous embodiment of the invention is that at least two different sized forms of the data carrier are punched simultaneously. This has the advantage that the punching of different geometries in a few operations is possible and thus significantly accelerates the entire process.

Another advantageous embodiment of the invention is that of

Disk is a SIM card. The SIM card is just one possible example of a data carrier. In principle, all other suitable data carriers can be produced by the method according to the invention.

Another advantageous embodiment of the invention is that the SIM card has the ID-000 format as the first geometric shape.

Another advantageous embodiment of the invention is that the SIM card has the mini-UICC format as a second geometric shape.

A further advantageous embodiment of the invention is that the SIM card has as a third geometric shape a geometric shape that is smaller than the mini UICC format.

Another advantageous embodiment of the invention is that the carrier has the ID-1 format.

Another advantageous embodiment of the invention is that the carrier and the data carrier made of plastic or laminated film layers.

In principle, any suitable material can be used. The data carrier can be made, for example, from an injection-molded plastic. Further features and advantages of the invention will become apparent from the following description of embodiments of the invention. The figures are not to scale representations of the exemplary embodiments. The same reference numerals denote the same components. The exemplary embodiments serve for explanation and a better understanding of the invention, wherein

Figure 1 shows the principle of the method according to the invention in a side view and

FIG. 2 shows a plan view of a carrier with a data carrier, wherein two smaller formats of the data carrier have been punched into the data carrier, the

are breakable.

FIG. 1 shows the principle of the invention in a side view. In a carrier 2 is punched by means of a first punching plate 4 and a second punching plate 6., The first punching plate 4 has a first punched profile 14 for a geometric shape of the data carrier. Accordingly, the second stamped sheet 6 has a second stamped profile 15 for the geometric shape of the data carrier. The first and the second

Although stamped profile 14 15 may differ, they all belong together to a geometric shape of the data carrier. For each geometric shape of the volume, e.g. ID-000 format or mini-UICC format, there are own punching profiles 14, 15. Each stamped sheet 4, 6 may have at least one stamped profile 14, 15. In the carrier 2 is punched from both sides, so that a defined material thickness 12 remains. The material thickness 12 is adjustable depending on the application and determines the necessary force to break the particular shape. The punching plates 4 and 6 are each connected by adapters 8 and 10 with a punching machine, wherein the punching machine has not been shown for reasons of clarity.

FIG. 2 shows the carrier 2 after punching according to the invention in a top view. The carrier is connected for example by means of three webs 22 with a data carrier, wherein the data carrier has a first geometric shape 16. The carrier 2 has for example, the ID-1 format. For the carrier 2, any other suitable format can be selected. In principle, it is also possible for the carrier 2 to be a band which is provided by a roll to the method according to the invention. Depending on the application, the number of webs 22 between one and more webs 22 may vary. The data carrier with the first geometric shape 16 has, for example, the ID-000 format as a geometric shape. The webs 22 each have a punched hole 24 shown in dashed lines, so that the disk with the first geometric shape 16 can be broken out of the carrier 2 by the user, the punch 24 according to the

inventive method was prepared. In the data carrier with the first geometric shape 16, a second geometric shape 18 and a third geometric shape 20 of the data carrier was further stamped according to the invention, each recognizable by the dashed line shown. The second form 18 is, for example, a mini-UICC format, and the third form 20 is, for example, a format that is smaller than the mini-UICC format. Any suitable shape can be chosen as the geometric shape of the data carrier. The second mold 18 and the third mold 20 are stamped into the first geometric shape 16 according to the invention so that they can be broken by a user along the dashed line. According to the invention, it is possible for a smaller geometric shape, for example the third shape 20, to be reinserted into a larger geometric shape, eg the second shape 18, if the user wishes to use the data carrier in a larger geometric shape. The smaller form is detachable, but permanently connected to the larger shape without the use of auxiliaries, such as an adhesive. To break the respective geometric shape of the data carrier, a force is applied by the user, which is determined by the material thickness 12, as described above in Figure 1.
