A perforation comprises at least one hole, but in particular several holes. The shape and size of the individual holes can vary. The form comprises in particular figures whose base corresponds to a circle, an ellipse or a polygon. Advantageously, the individual holes are arranged relative to one another in such a way that together they form a specific pattern, for example numbers of a serial number.

By means of a CO ₂ laser beam, a production of a conical perforation is possible. In such a perforation, the cross-sectional area of a hole in the plane in which the laser beam first encounters a security document has a maximum, and decreases on further passing through the security document. This form of perforation is advantageous because it provides additional protection against adulteration and / or total counterfeiting, since it is not to be produced by punching.

Perforations can penetrate a security document altogether. This means that a continuous perforation is made from the front to the back of the security document. In particular, in book-type security documents is also possible that the perforation is introduced so that not the entire security document is penetrated. Book-type security documents have pages and may also include a book cover comprising covers. Perforations can be made to penetrate only a predetermined number of sides and / or lids. In that case, the matrices are applied to the sides to be processed.

According to the invention, it is possible both for the security document to be applied to the die and for the die to be applied to the security document.

The device according to the invention is advantageous since it allows the security document to be applied to a die, through the cut-outs of which a laser beam can pass.

According to a further embodiment, the device comprises a second die. In this case, the device is set up in such a way as to position and / or fix a security document between the first die and the second die.

Replacement of a die may be necessary due to damage to a die. A simple and time-saving method of exchange has only a short-lived Downtime of the device result, so that the efficiency of the device is advantageously increased.

In addition, it is possible that for the production of perforations in different security documents, for example with different security standards, different matrices must be used. The advantageous embodiment with reversibly disposable die allows the device to be used in the production of different security documents. This is an economic advantage, since not their own devices for producing a perforation must be provided for their preparation, but only different matrices. Furthermore, it is advantageous that perforations can be produced in different security documents without having to increase the production area.

According to one embodiment of the invention it is provided that the device comprises a suction device or a connecting device for the purpose of fluidic connection of a suction device, wherein the suction device is particularly adapted for suction of perforation dust.

The advantage here is that a possibility for suction of perforation dust is given, so that the health and safety is increased. In addition, it is advantageous that less perforation dust can settle on parts of the device, which could otherwise lead to functional failures of the device, so that the maintenance effort is reduced.

According to a further embodiment, it is provided that the cavity formed by at least one recess of a female mold in the female mold is fluidically connectable or connected to the suction device or the connection device for the purpose of fluidic connection of a suction device, in particular for sucking perforation dust from the cavity formed by the recess in the mold.

Under perforating dust are the fine particles that arise during perforation in particular perforations by means of CO ₂ laser to understand. If perforation dust enters the respiratory system, it may cause respiratory irritation and possibly long-term damage. This inventive design of the device prevents in a particularly efficient manner such damage to people present.

Perpendicular to the plane in which the die can be applied to the security document, according to the invention, a recess penetrates the entire die. The cavity in the die is from the plane in which the die is applied to the security document and bounded by a plane running parallel to the plant levels. Laterally, the cavity is limited by the material of the die.

This embodiment of the invention is advantageous, since in this way suction of the perforation dust is made possible, in particular at a small distance from its region of origin. The perforation dust is extracted efficiently and reduces the proportion of dust that can spread over the air. In terms of occupational safety, this is advantageous. Furthermore, it is advantageous that only small amounts of perforation dust can cause contamination of the device or individual device elements, so that the maintenance effort is reduced.

A further embodiment provides that the device further comprises at least one line element which is fluidically connected on the one hand with the cavity formed in the die by a recess and on the other hand with the suction device or the connecting device for the purpose of fluidic connection of a suction device for the purpose of suction of perforation dust from the recess formed in the cavity in the die.

Here, under line elements are to be understood in particular gas line elements.

According to a further embodiment, the device is set up such that it comprises an enclosure for the purpose of emission protection.

According to the invention, at least the area of the device in which the matrices are located is enclosed. Through the emission protection of the occupational safety is further increased, since a diffusion of perforation dust, which was not sucked out of the cavities of the die, is prevented.

The emission protection of the device by the enclosure ensures, according to DGUV, that a maximum permissible irradiation, also by reflected or scattered laser radiation, is not exceeded. Likewise, the enclosure represents another barrier to the resulting decomposition products of the laser-matter interaction in the form of removal of material by evaporation.

According to one embodiment of the invention, the device comprises a traversing device, which is a movement of the device or of modules of the device from a Working position allows in a maintenance position, in particular parallel to the plane in which the die can be applied to the security document.

This allows easy access to areas or modules of the device. This is advantageous in particular in the case of an embodiment of the device according to the invention which permits extraction in a small space, emission protection and the interchangeability and pneumatic mobility of the dies.

A further embodiment provides that the device comprises a displacement measuring system, which is mechanically connected to at least one die, so that from the distance of the matrices to each other information with respect to the thickness of the material located between the matrices of the security document can be generated and this information for setting the Laser power is recoverable.

It is meant by the distance of the matrices to each other their distance perpendicular to the support plane of the security document. The distance can be determined based on the position of the matrices to each other. Alternatively, according to the invention, the distance can be detected by the position of at least one device element connected to a die.

The material of the security document located between the matrices may be the entire security document. If perforations in a book-like security document are to be introduced such that only a predetermined number of pages and / or covers should be penetrated, the material located between the dies comprises the pages to be processed.

The advantage of this device according to the invention is that the laser power can be adjusted on the basis of the thickness of the security document or the sum of the sides to be processed. In this way, the laser power required for a precise perforation can be made available.

A further aspect of the invention relates to a method for producing a perforation in a security document, in particular in a book-type identification document such as a passport book. In this case, an apparatus according to the invention for producing a perforation in a security document is provided. A security document is fed to this device and applied to at least one die or the die is applied to the security document. At least one perforation is introduced into the security document by means of at least one laser beam.

Since the die according to the invention has at least one recess, the laser beam, the recess and thus the die and the security document or to penetrate processing pages of the security document, while ensuring the desired position of the elements to be perforated.

According to one embodiment of the method, at least one die is moved, in particular moved pneumatically. This causes a squeezing of a security document between two dies.

According to a further embodiment, it is provided that when pressing the security document from the distance of the matrices to each other information about the thickness of the material located between the matrices of the security document is generated and this information is used to adjust the laser power.

The advantage of this method according to the invention is that, based on the thickness of the pressed security document or the sum of the pressed sides to be processed, the laser power required for a precise perforation can be set.

Furthermore, an automation of production is made possible, so that the efficiency can be increased.

According to a further embodiment of the method, it is provided that perforation dust is extracted from at least one cavity formed in a recess of a die in a die.

This is advantageous because suction of the perforation dust is made possible at a small distance from its area of origin. The proportion of dust that can spread over the air is reduced. This is advantageous in terms of occupational safety.
