Description

Method and device for producing a security document and security document

The invention relates to a method and an apparatus for producing a

Security document, in particular a book-type security document, as well as a security document.

DE 101 24 068 A1 discloses an apparatus and a method for the automatic positioning and trimming of cut material from paper materials or

paper material-like, stackable materials, in particular for three-sided

Trimming bound printed products. The described device has two orthogonal and phase-offset cutting blades. The knives make a simultaneous cut through different sections of the material to be cut.

The problem here is that the punching process described in the document is susceptible to wear and failure. In particular, an effort to change and set up the cutting tool is time consuming and costly. The quality control for documents produced in this way is complicated, since usually a visual inspection and a corresponding readjustment of the cutting tools must be done. In particular, in a so-called three-side cutting tool and the adjustability of

Limited restriction. For example, e.g. only one simultaneous move all

Cutting edges parallel to the surface of the material to be cut possible. The well-known

However, punching processes only allow the production of security documents with straight and non-bevelled edges.

The subsequently published DE 10 2015 219 732.8 describes an apparatus and a method for producing a security document, wherein the security document is provided in an oversize format, wherein the security document is trimmed in at least one edge region, wherein the trimming along a

Circumcision trajectory is done, the circumcision is performed temporally and spatially along the circumcision trajectory ongoing.

It is desirable to further increase the security against forgery of security documents. The technical problem arises of providing a method and a device for producing a security document as well as a security document which provide increased security against forgery of the security document.

The solution of the technical problem results from the objects having the features of claims 1, 10 and 11. Further advantageous embodiments of the invention will become apparent from the dependent claims.

It is a basic idea of the invention to form at least a portion of a longitudinal and / or transverse edge of the security document with an odd and / or bevelled contour.

A method for producing a security document is proposed. The security document can in this case have a desired format, for example an ID1 format, an ID2 format or an ID3 format. Preferably, but not necessarily, the security document is a book-type security document. A book-like

Security document may include a cover part and a book block part, wherein the cover part surrounds the book block part in the closed state of the security document. Alternatively, however, the security document may also be provided as a card body.

The security document is provided in an oversize format. This may mean that at least one dimension, for example a length, a width or a height, is greater than the desired or final dimension in the finished manufactured state of the security document. The finished state may indicate a ready-to-use state. Preferably, two dimensions, preferably the length and width, are larger than the corresponding desired dimension. For example, a

Security document in one or more edge regions having a projection with a predetermined dimension along the corresponding spatial direction, for example along a longitudinal or transverse direction. The supernatant may be for example 5 mm. In a book-like security document, for example, three edges may each have a projection, in particular two transverse edges and a longitudinal edge. In this case, the security document can have no projection only in the edge forming the book spine. The supernatant may also be referred to as a bleed addition. In a card-shaped security document However, this may, of course, each have a projection along all four edges.

The security document can be cropped in at least one border area or in selected, but not all, border areas or in all border areas. The circumcision is done along a circumcision trajectory.

The trimming trajectory may in particular comprise a section for producing at least one transverse edge. This means that a trimming along the trimming trajectory truncates along the transverse edge of the security document then cut out. Accordingly, the

Circumcision trajectory comprise a section for producing at least one longitudinal edge.

It is possible, but not essential, that a length of a transverse edge is shorter than the length of a longitudinal edge. Furthermore, the longitudinal and transverse edges can be oriented substantially perpendicular to one another. Furthermore, it is possible that a book edge forming edge region forms a longitudinal edge. Cross edges can also be arranged in particular on end faces of the security document.

Also, the circumcision trajectory may be at least one or more

Include connecting sections. The trimming trajectory in the connection section here combines a trimming trajectory in a transverse edge section and the trimming trajectory in a longitudinal edge section. In the connecting section, the circumcision trajectory and thus also a course of the edge can be curved. Such a curved section may in particular be a circular arc-shaped section. This circular arc-shaped portion may have a predetermined radius, in particular a radius from the range of 1 mm to 5 mm, preferably from a range of 2.5 mm to 4 mm.

It is important that for the purposes of this invention, a portion of the transverse edge and a portion of the longitudinal edge do not include the connecting portion. In particular, the

Connecting portion no part of a portion of a transverse edge or a

Longitudinal edge. According to the invention, the trimming produces an odd and / or beveled course of at least one section of a longitudinal edge and / or an odd and / or bevelled course of at least one section of the transverse edge. In particular, the course may designate a course of a surface of the edge or a course of points along this surface.

Of course, an odd and / or beveled course in several mutually different or spaced sections of the longitudinal edge and / or the transverse edge can be made.

An edge of the security document may have a predetermined height, the height being detected, for example, in a direction perpendicular to a front or back side of the security document.

The following coordinate system will be referred to below. A

Vertical axis of the security document may be oriented perpendicular to the front and / or back of the security document. A longitudinal axis may extend parallel to a longitudinal edge. A transverse axis may extend parallel to a transverse edge. However, this does not necessarily mean that the longitudinal axis is parallel to each section of the longitudinal edge and / or the transverse axis is parallel to each section of the transverse edge.

In an odd and / or beveled portion of the longitudinal edge, in at least one point of the portion, a normal vector oriented perpendicular to a tangent plane at that point may include an angle other than zero with the transverse axis. Thus, the normal vector is not parallel to the transverse axis at this point. Also may be odd and / or beveled

Section of the longitudinal edge of the normal vector at all points of this section with the transverse axis enclose an angle which is not equal to zero. In this case, however, a value of the angle or the value of directional components of the normal vector can change.

The normal vector may comprise exactly one or more of the following directional components: a) a directional component oriented parallel to the longitudinal axis, b) a directional portion which is oriented parallel to the vertical axis.

In both cases, it is possible, but not mandatory, for the normal vector also to include a directional component which is oriented parallel to the transverse axis. It is also conceivable that the normal vector is oriented completely parallel to the longitudinal axis or completely parallel to the vertical axis.

Of course, an odd and / or beveled portion of the longitudinal edge may comprise a plurality of subsections in which points have equally oriented normal vectors.

Thus, with a straight and non-tapered portion of the longitudinal edge, a normal vector of a tangent plane may be oriented at points of the portion parallel to the transverse axis.

In an odd and / or beveled portion of the transverse edge, in at least one point of the portion, a normal vector oriented perpendicular to a tangent plane at that point may include an angle non-zero with the longitudinal axis. Thus, the normal vector is not parallel to the longitudinal axis at this point. Also, with an odd and / or beveled portion of the transverse edge, the normal vector may include an angle other than zero at all points of that portion with the longitudinal axis. In this case, however, a value of the angle or the value of directional components of the normal vector can change.

The normal vector can be exactly one or more of the following

Directional components include: a) a directional component oriented parallel to the transverse axis,

b) a directional component which is oriented parallel to the vertical axis,

In both cases, it is possible, but not mandatory, that the normal vector also comprises a directional component which is oriented parallel to the longitudinal axis. It is also conceivable that the normal vector is oriented completely parallel to the transverse axis or completely parallel to the vertical axis. Of course, an odd and / or chamfered portion of the transverse edge may comprise a plurality of subsections in which points have equally oriented normal vectors.

Thus, for a straight and non-tapered portion of the transverse edge, a normal vector of a tangent plane may be oriented at points of the portion parallel to the longitudinal axis.

In a section with an odd course, in particular, a curved course can be formed. A curved course can be a fixed one

Have radius of curvature. Also, a radius of curvature and / or a direction of curvature along the edge may change.

In a section with a beveled course can also be an inclined, but flat, surface formed.

It is important that the section according to the invention with the odd and / or beveled course does not designate a connecting section between a transverse edge and a longitudinal edge.

By providing an edge section with an odd and / or

beveled course can be provided in particular an additional security feature. For example, in an authenticity check of the

Security document are checked whether the security document has a border section with the explained odd and / or beveled history. If this is the case and, if necessary, further security features can be verified, a genuineness of the security document can be verified. If this is not the case, the authenticity can not be verified.

In a further embodiment, at least one elevation and / or at least one recess and / or at least one rounding and / or at least one bevel of the edge are produced or formed by the odd and / or beveled profile. For example, by the odd and / or beveled curve in one or more sections, a dot pattern can be made or formed, wherein dots are formed as elevations. The elevations may be tactile, in particular by fingertips, detectable.

In particular, the dot pattern may form an element or part of a Braille element, in particular Braille. An element may e.g. be a letter or a symbol of braille.

Also, in the section, a wave-shaped course of the edge can be produced. Alternatively, a serrated, e.g. a zig-zag shaped course, are produced. Also, an edge can be made with grooves or indentations.

This results in an advantageously identifiable course of the edge, which in turn is an easy-to-implement, timely and reliable fast authentication possible.

In another embodiment, the history encodes information. For example, the course or at least one property of the course can be detected, in particular optically, haptically or by further, suitable detection methods. It is e.g. possible that a two- or three-dimensional image of the edge is generated. In

Depending on the detected history, the information can then be decoded. In this case, of course, there can be an unambiguous association between the course, in particular one or more properties of the course, and the information. The information can be, in particular, document-specific or individual information.

If a dot pattern is produced or formed in one or more sections by the odd and / or beveled pattern, then this dot pattern can form the desired information or a part thereof in Braille. For example, For example, a braille serial number can be represented by the odd and / or beveled history.

The previously explained authenticity check can then be carried out depending on the information. For example, in an authenticity check of the Security document are checked whether the encoded information corresponds to a specified information. The specified information can be stored, for example, in particular in a database or a corresponding memory device. If this is the case and, if necessary, further security features can be verified, a genuineness of the security document can be verified. If this is not the case, the authenticity can not be verified.

This results in an advantageous manner a further improvement of

Forgery.

In a further embodiment, the course encodes an already in

Security document existing information. For example, the history may encode a serial number of the security document or a part thereof, a name of a person authorized to keep the security document or a part thereof or further information of the security document. In this case, the history of the section may be different for each security document.

This results in an advantageous manner a further improvement of

Forgery. For example, in an authenticity check of the

Security document, whether the encoded information corresponds to a, in particular specified, information of the security document. For this, the further information e.g. also be recorded or determined. If this is the case and, if necessary, further security features can be verified, a genuineness of the security document can be verified. If this is not the case, the authenticity can not be verified.

In a further embodiment, the course is a document-specific course. This may mean that a specific history exists for each security document, it being understood that courses of various security documents may differ from one another. In particular, the course can be an individualized course. This can mean that the course is an identity one for the leadership of the

Security document authorized person coded.

The previously explained authenticity check can then be carried out depending on the information. For example, in an authenticity check of the Checking whether the history corresponds to a document-specific history or an individualized history. This can be done, for example, by comparing at least one property. If this is the case and, if necessary, further security features can be verified, a genuineness of the

Security document. If this is not the case, the authenticity can not be verified.

For example, the security document or the person authorized to keep the security document can be identified. The document-specific or individualized course or at least one property can be stored, for example, in particular in a database or a corresponding memory device and retrieved depending on the identified security document or the identified authorized person.

In a further embodiment, the odd and / or beveled portion is a portion of a transverse edge, wherein a center of the portion is closer to a

Book spine edge is arranged as at a longitudinal edge, which is opposite to the book spine edge. In this case, the security document may in particular be a book-type security document. This results in an advantageous manner that a user is less irritated in handling the security document by the odd and / or beveled section, since the manual handling is usually in the region of the longitudinal edge, which is opposite to the spine edge.

In a further embodiment, the odd and / or beveled portion extends only over part of the height of the rim. For example, The section can only be in one area of the edge of the front of a book-like

Security document, but not in the area of one edge of the back, be made. For example, For example, the portion may be made only in an area of an edge of a front cover part of a book-like security document, but not in the area of an edge of a back cover part.

By virtue of this additional feature, an anti-counterfeiting security can advantageously be further increased; in particular, such courses can not be produced by known punching methods. In a further embodiment, the circumcision is performed continuously in time and space along the circumcision trajectory. This can mean that the circumcision is performed temporally and spatially continuously along the circumcision trajectory. Thus, at a first point in time, the circumcision may be performed at a first point or portion of the circumcision trajectory, at a time immediately following, in particular immediately following, the circumcision at a spatially, particularly immediately adjacent, point or portion of the circumference

Circumcision trajectory is performed. The circumcision running temporally and spatially along the circumcision trajectory can be carried out, for example, by moving at least one cutting device and / or the security document in such a way that the cutting device is moved along the circumcision trajectory, in particular continuously. Thus, the oversized security document and the cutter may provide one, in particular continuous,

Perform relative movement to each other such that the circumcision along the circumcision trajectory.

The oversized security document may in particular have a rectangular cross-section. The trimmed security document may also contain a substantially, i. except for the odd and / or tapered sections, have rectangular cross-section.

As will be explained in more detail below, the circumcision running in time and space along the circumcision trajectory, in particular continuous

Pruning, increased flexibility when cropping the security document in oversize. In particular, the circumcision trajectory can be chosen such that the circumcision can thus be carried out in such a way that an odd and / or beveled section can be produced or formed in an edge region.

Furthermore, a trimming independent of the remaining edge region can be carried out for each edge region. For example, a dimension of the section (ie, the truncated part) in an edge region, as opposed to the well-known three-side trimming, can be selected independently of the dimension of the section in the remaining edge regions. This also applies, for example, to the orientation of a straight-line circumcision trajectory. In another embodiment, the trimming is done by milling. For this purpose, the cutting device may be formed as a milling device. This allows in

Advantageously, a simple maintenance or a simple change of

Cutting device, since, for example, only one milling head must be replaced. The replacement can be done automatically.

Alternatively, the circumcision is done by grinding. For this purpose, the circumcision can therefore be carried out by a grinding device. For this purpose, the cutting device may be formed as a grinding device.

Further alternatively, the trimming can be done by fluid jet cutting, in particular water jet cutting. In this case, the trimming can be performed by a fluid jet cutter. This can comprise at least one nozzle head and fluidic connection elements. Furthermore, this device may comprise a pressure generating device, which has a desired

Fluid pressure provides to squeeze the fluid from the nozzle and provide the corresponding cutting beam. The pressure generating device can hereby

Of course, supply several nozzle heads.

Further alternatively, the trimming can be done by a cutting knife or a stylus. These can be moved to perform the circumcision accordingly.

Further alternatively, the trimming can be done by laser beam cutting.

Overall, results in a space-saving and easy to maintain cutting device in an advantageous manner.

It is possible that the cutting device by a corresponding

Positioning device, such as a so-called XY actuator or an XYZ actuator can be moved. In this case, the security document in oversize, so the cut material, be arranged stationary. Alternatively, the at least one

Cutter be arranged stationary, the security document in the

Oversize can be moved by a corresponding positioning. Further alternatively, both the security document in oversize and the at least one cutting device to be moved by appropriate positioning.

The at least one positioning device can thus move the cutting device and / or the security document in oversize format, in particular with one

Translational motion. Alternatively or cumulatively, a rotational movement may also be possible.

Furthermore, a spatial position of the circumcision trajectory can be determinable. The

Space position can be given here in particular in a document-fixed coordinate system. The spatial position can be a position and / or orientation of the

Designate circumcision trajectory. The spatial position of the circumcision trajectory can be given for example by the position of a point or selected points or all points of the circumcision trajectory. Also, an orientation of straight sections of the circumcision trajectory can be adjusted. The orientation can also be given in the document-fixed coordinate system.

Further alternatively or cumulatively, a form of the circumcision trajectory can be determined. In particular, the shape can be adjusted such that the circumcision trajectory has a desired course.

In a book-type security document, the circumcision trajectory preferably comprises three substantially straight edge portions and two

Connecting portions, wherein a connecting portion connects two of the straight sections. In an edge section may be one or more odd and / or

be provided chamfered sections.

In this case, the position and the orientation can be determined for each section. Also, for each section, the shape of the circumcision trajectory can be determined.

Preferably, the spatial position and / or shape can be determined independently of one another for a plurality of sections of the circumcision trajectory. This means that the spatial position and / or shape of one section has no effect on the spatial position and / or shape of another section. Further, the trimming for each section can be performed independently of the other sections. Here, the spatial position and / or the shape of the circumcision trajectory or

their sections are customized for each document. This means that for each document, in particular for security documents which follow one another directly in time during the production process, the circumcision trajectory can be set independently of one another.

Furthermore, it advantageously results that a trimming as well as a contour of the edge can be set section-specific for each section of the security document to be trimmed. Cropping preceding process steps in the production of the security document may cause undesirable variations in the relative locations and / or orientations of features or components of the security document

Security document occur to each other. These unwanted deviations may vary from security document to security document. For example, in the case of a first security document, a graphic element arranged on the front side, for example an embossing, may not be at desired distances from the

Edges, especially au ßermittig be arranged. At another

Although the security document can use the graphic element on the front page

desired distances from the edges, so for example centrally located, but with a further feature has an undesirable deviation from a desired position. For example, a graphic element of an inner side, in particular a passport, may have an undesired distance from edges of this inner side. The document-specific determination of the circumcision trajectory, in particular of sections of the circumcision trajectory, allows in both cases that a trimming can be carried out in such a way that in each case a desired position of the features or graphic elements can be ensured. Thus, advantageously, a scrap amount can be reduced.

Furthermore, the safety document and / or the at least one cutting device can be moved to carry out the trimming. This can be done by one or more positioning. This has been explained previously. This results in an advantageous manner, a reliable and accurate implementation of circumcision temporally and spatially along the circumcision trajectory. Furthermore, at least one image of the security document, in particular of the

Security document in oversize. The image can be generated by an image generation device, in particular a camera.

Furthermore, image-based, a document-related spatial position of at least one

Document feature can be determined, the circumcision trajectory in

Dependence of the document-related spatial position of the at least one

Document feature is determined.

Furthermore, the circumcision trajectory can be determined such that a

cropped format does not deviate more than a predetermined amount from a desired format. This may mean that a length and / or width and / or height of the trimmed security document does not deviate more than a predetermined amount from a desired length or desired height. This can be a first

Format criterion be.

Alternatively or cumulatively, the circumcision trajectory can be determined such that a document - related spatial position of a document feature in the

clipped state of the security document does not deviate more than a predetermined amount from a desired spatial position. In particular, the

Circumcision trajectory be determined so that a document - related spatial position of an image or non - reproducible document feature in

clipped state of the security document does not deviate more than a predetermined amount from a desired spatial position.

However, the circumcision trajectory can be determined such that the

Security document has the desired contour.

Furthermore, the security document can be provided with at least one supernatant position. An edge region of the supernatant layer may have at least one optical landmark. The supernatant layer may in particular be part of the previously described book block part. The supernatant layer can be provided in particular by at least one side of the book block part. Pages of the book block part can e.g. to register for a visa. Preferably, the supernatant layer of a

Passport page of the book block part provided. Such a passport page serves in usually not for entering a visa. Pages of the book block part may be made of paper, plastic or a composite material, for example. In other words, the supernatant layer has at least one section which extends over at least a part of at least one side edge of the security document in

Oversize survives. This section can also be referred to as the projection section. For example, the supernatant section can protrude 3 mm to 6 mm beyond the side edge.

The projection section can in this case protrude along the entire side edge. In this case, the supernatant portion may be formed strip-shaped. Also, the supernatant portion can survive only along a part of the side edge. Also, the supernatant portion may include a plurality of subsections, each protruding along a portion of the side edge.

Further, an image of at least the supernatant portion of the supernatant layer is generated. Preferably, an image of the security document in oversize with the

Projection section generated.

In a first alternative, a document-related spatial position of the supernatant section is determined image-based. A document-related spatial position can be a spatial position in a document-fixed coordinate system of the uncircumcised

Security document, ie the security document in oversize.

The spatial position of the supernatant section may, for example, be fixed as the spatial position of a document feature of the protrusion section, a reference point or a reference line of the protrusion section or a protrusion section

Coordinate system can be determined. For example, an origin of this

Coordinate system at a corner or in a geometric center of the

Überstandsabschnitts lie. Next, axes parallel to edges of the

Supernatant section be oriented.

The document-related spatial position can also be a spatial position of the overhang section relative to a document feature, in particular one shown

Document feature of the uncut security document. This can also be referred to as Relativraumlage. For example, the Relativraumlage be a distance of the portion of a document feature, such as an edge of the document.

The spatial position of an image feature or document feature can be a position and / or orientation of the feature in relation to the corresponding image (s)

Designate coordinate system.

Further, depending on the document related spatial situation of the

Supernatant section determines a document-related spatial position of at least one unimaged document feature of the security document.

The spatial position of a not shown document features relative to

Projection section may be previously known. In particular, the spatial position of a document feature not shown in the supernatant section can be fixed

Coordinate system previously known. Since the document-related spatial position of the supernatant section, in particular a coordinate system of the

Supernatant section, is known, the document-related spatial position of the document feature not shown can be determined.

The document feature, not shown, designates a document feature which can not be imaged into the image by means of the image generation device, and thus can not be detected in the image. A non-reproducible document feature can thus also be referred to as a document feature that is not visible or hidden, in particular a document feature that is not visible or hidden in the closed state of the security document.

An unimaged document feature may, in particular, be a feature that is located in or on one side of the book block portion. Preferably, the document feature not shown is a document feature which is arranged in or on the supernatant layer but not in the region of the projection section.

Furthermore, a circumcision trajectory is determined as a function of the document-related spatial position of the non-illustrated document feature of the security document. In a second alternative, image-based a document-related spatial position of an imaged document feature of the supernatant section and a

Circumcision trajectory determined depending on the document-related spatial position of the imaged document feature of the supernatant section.

Further, a circumcision trajectory depending on the spatial position of at least one imaged document feature of the protrusion portion in the

document-fixed coordinate system of the uncut security document determines a circumcision trajectory.

In the second alternative, the image-based determination of the document-related spatial position of the supernatant section is not absolutely necessary. However, in the second alternative image - based documentary spatial position of the

Supernatant section are determined, depending on the

document - related spatial position of the supernatant section a document - related spatial position of at least one displayed document feature of the

Supernatant section and a circumcision trajectory depending on the document - related spatial position of the imaged document feature of

Supernatant section is determined.

For example, the document-related spatial position of the protrusion section and / or the document-related spatial position of the at least one unimaged document feature of the security document can be determined as a function of at least one imageable feature of the supernatant position. The imageable feature can be arranged in particular on the projection section.

In particular, the supernatant portion of the supernatant layer may comprise at least one optical landmark, wherein the optical landmark forms the imageable feature. An optical landmark can be a sign which can be detected easily, quickly and reliably in an image. For example, an optical landmark may be or include a registration mark, a line, a square, a circle element, a 2D or 3D bar code, a target element, two adjacent squares at a corner, or a punch. The optical landmark can be lasered, printed or punched. Also, the supernatant portion of the supernatant layer may have an identification feature, which allows identification of the security document. Such an identification feature can be designed, for example, in the form of a barcode. The identification feature can also form an optical landmark here.

The at least one optical landmark and / or the identification feature can be arranged, for example, in the production of the supernatant layer on, in or on the supernatant layer.

A relative position and / or orientation of non-imaged document features to the at least one optical landmark may be previously known. In particular, the supernatant layer may have been produced such that the relative positions and / or orientation are within a predetermined range.

Since the non-reproducible document features, in particular document features of the supernatant layer, are not optically detectable, in particular camera-based, in a closed state of the book-type security document, the optical detection of the at least one optical landmark thus makes it possible to determine the document-related spatial position of the non-imaged feature.

For example, a non-mappable document feature may be a signature area. A spatial position of the signature area relative to the

mappable feature of the supernatant layer may be previously known. Due to the optical detection of this feature, the document - related spatial position of the

Signature area can be determined, even if the signature area can not be visually detected immediately.

In the case explained above, the circumcision trajectory can then be determined such that the e.g. arranged inside the security document

Signature area a desired distance from the edge of the cropped

Security document.

Of course, the method is also applicable to non-book-type security documents, such as security documents in card format. In this case can the supernatant layer be an inner layer of the card body, for example a

Hologram layer and / or a so-called inlay layer and / or a personalized lamination layer.

In a further embodiment, the circumcision trajectory has at least one part-circular section. This has already been explained above. As a result, requirements for producing the security document can be met in an advantageous manner.

Furthermore, the security document can be provided as a book-like security document. In particular, the book-type security document may be provided in oversize in a closed state.

Further proposed is a security document, in particular a book-like security document. The security document has at least one longitudinal edge and at least one transverse edge.

According to the invention, at least a portion of the longitudinal edge and / or at least a portion of the transverse edge has an odd and / or beveled course. In particular, the security document can be produced by a method according to one of the embodiments described in this disclosure.

In particular, at least one elevation and / or at least one recess and / or at least one rounding off and / or at least one beveling of the edge can be produced by the odd and / or beveled profile. Furthermore, the course can encode information. Furthermore, the history can encode information already present in the security document. Furthermore, the course can be a document-specific course. Further, the portion may be a portion of a transverse edge, wherein a center of the portion is located closer to a spine edge than to a longitudinal edge opposite the spine edge.

Further, the odd and / or chamfered portion may extend only over part of the height of the rim. This and corresponding advantages have already been explained above. Further proposed is a device for producing a security document. By means of the device, a method for producing the security document according to one of the embodiments written in this disclosure is feasible. Thus, the proposed device is designed such that such a method by means of the device is feasible.

The device comprises at least one cutting device and at least one holding device for the security document. The security document can be arranged on, on or in the holding device. Further, the cutter is movable. Alternatively or cumulatively, the at least one holding device is movable. The device may comprise corresponding positioning devices for this purpose.

Further, the security document can be trimmed by means of the cutting device in at least one edge region, wherein the trimming along a

Circumcision trajectory is done.

According to the invention, the trimming results in an odd and / or beveled course of at least one section of a longitudinal edge and / or at least one

Section of a transverse edge of the security document produced. This and

corresponding advantages have been explained previously.

Furthermore, the circumcision is temporally and spatially, in particular continuously, continuously feasible along the circumcision trajectory. This may mean that the

Circumcision is feasible by the at least one cutting device, in particular continuously, along the circumcision trajectory is moved. This in turn includes the case that the cutting device and the holding device perform a relative movement to each other such that the at least one

Cutting device along the circumcision trajectory is moved.

Furthermore, the device may comprise at least one control device for controlling the movement of the cutting device and / or the holding device.

This advantageously results in an apparatus for document-specific and flexible trimming of a security document in oversize format, whereby a scrap quantity in the production of security documents can be reduced. Furthermore, the device may comprise at least one device for image acquisition and at least one evaluation device. The device for image acquisition and the at least one evaluation device can be connected signal and / or data technology. Furthermore, an image of the security document can be generated by means of the image capture device. Furthermore, by means of the evaluation device, a document-related spatial position of at least one document feature can be determined, wherein the circumcision trajectory is dependent on the document-related

Space position of the at least one document feature can be determined.

For example, can by means of the evaluation an image-based evaluation of a

Formatkritiums feasible and depending on the evaluation of a

Circumcision trajectory be determinable. This has been explained previously. Depending on the circumcision trajectory thus determined, the

previously explained control device, the positioning / en the

Control cutting device and / or the holding device such that the

Cutting device along the circumcision trajectory is moved.

Furthermore, the holding device for the security document can comprise a first and a further holding plate, wherein the security document can be arranged between the first and the further holding plate. In particular, the security document can be clamped between the first and the further holding plate.

Furthermore, the first and / or the further retaining plate has a trimming slot. The trimming slot can in this case designate a, in particular elongate, through opening in the respective holding plate. In particular, a dimension of the trimming slit may be chosen such that trimming trajectories having a set of different spatial positions and / or different shapes may be used for trimming.

Alternatively, the first and / or the further holding plate has a sub-format. This means that the first and the further retaining plate is formed in at least one, two or all dimensions smaller than the corresponding dimension of the security document in the trimmed state or in oversize. This results in an advantageous manner a stable arrangement of the security document during the trimming process, wherein in the trimming process either a cutter or the holding plates or both

The invention will be explained in more detail with reference to an embodiment. The figures show:

3 is a schematic flow diagram of a method according to the invention,

Fig. 4 is a schematic plan view of a portion of a

Security document and

5 shows a schematic longitudinal section through a security document.

Hereinafter, like reference numerals designate elements having the same or similar technical features.

1 shows a schematic plan view of a security document 1, which may be a book-type security document 1. The security document 1 has an oversize format. The uncut security document 1 in oversize is shown by solid lines. The security document 1 in cropped format, which can be, for example, an ID3 format, is shown by a dashed line.

The security document 1 in oversize has a first longitudinal edge 2a, which forms a spine. The security document 1 is here in the closed State shown. Next, the security document 1 in oversize on a further longitudinal edge 2b, a first transverse edge 3a and a further transverse edge 3b. The distance between the edges 2a, 2b, 3a, 3b and the corresponding edges in the end format may also be referred to as a protrusion or bleed of the security document 1 in oversize.

Also shown are a first longitudinal edge 18a, a further longitudinal edge 18b, a first transverse edge 19a and a further transverse edge 19b of the security document 1 in the final format. Also shown is a portion 20 of the first transverse edge 19a, which has an odd and / or beveled shape, in particular a wave-shaped course. Also shown is a section 21 of the further transverse edge 19b, which likewise has an odd and / or bevelled course, in particular a wave-shaped course.

It is further shown that the security document 1 on a front side 4 comprises a graphic element 5, which e.g. may be formed as a gold stamp.

It is further shown that the security document 1 in oversize a

Supernatant layer 6, wherein an edge region 7 of the supernatant layer 6 has optically detectable landmarks 8. This edge region 7 can also as

Supernatant section are called. The supernatant layer 6 in this case refers to a page or double page of a book block, not shown, which is enclosed in the closed state of the book cover. The edge region 7 of the supernatant layer 6 projects in the closed state over a side edge, in this case over the first transverse edge 3 a, of the security document 1 in oversize or of the cover part in FIG

Oversize beyond. Thus, the optically detectable landmarks 8 in the closed state of the security document 1 in oversize by an image capture device 9 (see FIG. 2) detectable.

In Fig. 1 it is shown that the optically detectable landmarks have two squares of the same size and with mutually parallel edges, with the squares intersect at exactly one corner, this point can be referred to as the reference point of the optical landmark 8. The optically detectable landmarks 8 have a predetermined distance and a predetermined orientation (relative) to further features (not shown) of the supernatant layer 6. The supernatant layer 6 may be formed, for example, as a laminated passport plastic, which in addition to the optically detectable landmarks 8 a non-optically detectable in the closed state passport photo, also not optically detectable signature field and other (graphic) elements and security features. These (safety) features can be a predetermined distance and a

have predetermined orientation (to) the optically detectable landmarks 8 and a connecting line between the reference points of the optical landmarks 8.

Also shown is an exemplary document-fixed coordinate system with a longitudinal axis x and a transverse axis y, wherein arrows have a longitudinal direction and a

Symbolize transverse direction. The document-fixed coordinate system may have an origin which is arranged in a geometric center of the security document 1 in oversize format. Thus, a position and orientation of the optically detectable landmarks 8 in the document-fixed coordinate system can be determined. The orientation may, for example, as orientation of a connecting line of the

Reference points of the optically detectable landmarks 8 are determined. This in turn makes it possible to determine a position and orientation of the explained further features and safety features of the supernatant layer 6, which are not optically detectable in the closed state, in the document-fixed coordinate system.

Next is also a position and orientation of the graphical element 5 in FIG

document-fixed coordinate system determinable. For example, a position may be a geometric center of the graphical element 5 or a point of predetermined properties. An orientation may, for example, be an orientation between two characteristic points of the graphic element 5 or an orientation of a side edge of the graphic element 5.

Next is a position and orientation of the side edges 2a, 2b, 3a, 3b of the

Security document can be determined in the oversize format in the document-fixed coordinate system.

The security document 1 shown in Fig. 1 can by means of a

Image capture device 9 (see Fig. 2) are optically detected. A control and evaluation device 10 (see FIG. 2) can then perform an image-based evaluation of Perform format criteria. Depending on a result of the evaluation, a circumcision trajectory 1 1 can then be determined, wherein the

Circumcision trajectory 1 1 defines a course or a contour of the edges 18 a, 18 b, 19 a, 19 b of the trimmed security document 1, in particular also a course of the sections 20, 21.

In particular, the circumcision trajectory 11 may comprise three sections 12a, 12b, 12c, wherein a first section 12a and a second section 12b are connected by a first connection section 13a. The second portion 12b and a third portion 12c are connected by a second connecting portion 13b. The connecting portions 13a, 13b may have a predetermined radius.

In this case, a contour of the first transverse edge 19a of the trimmed security document 1 is determined by the first section 12a. Next is through the second

Section 12b a contour of the further longitudinal edge 18b of the trimmed

Security document 1 set. Next, a contour of the second transverse edge 19b of the trimmed security document 1 is determined by the third section 12c. In particular, the circumcision trajectory 1 1 can also define the contour of the wave-shaped sections 20, 21.

The circumcision trajectory 1 1 here denotes a trajectory, along which the security document 1 and a cutting device 1 1 for carrying out the

Circumcision be moved relative to each other.

The circumcision trajectory 11 may in this case be determined such that one, several or all of the following format criteria are fulfilled. In particular, a spatial position and shape of the circumcision trajectory 1 1 can be fixed in the document

Coordinate system can be chosen such that

a) a section 20 of a transverse or longitudinal edge 18a, 18b, 19a, 19b has an odd and / or bevelled course,

b) a format of the trimmed security document 1 corresponds to a desired end format or does not deviate more than a permissible extent from this final format,

c) a relative position and a relative orientation of the graphic element 5 to the side edges of the trimmed security document 1 of a desired corresponds to a relative position or a desired relative orientation or deviates no more than a predetermined desired degree thereof,

d) a relative position and relative orientation of at least one non-optical

detectable feature of the supernatant layer 6 to the side edges of the trimmed security document 1 a desired relative position or relative

Orientation or does not deviate more than a predetermined amount from it.

If not all format criteria b) to d) can be completely fulfilled, a weighting of the format criteria can be carried out. For example, the fulfillment of the format criterion b) can be weighted higher than the fulfillment of the format criterion d). However, it must be ensured that all format criteria are still met while adhering to permissible tolerances.

A spatial position of the circumcision trajectory 1 1 can be determined in the document-fixed coordinate system. The spatial position may, in particular, designate a spatial position of the sections 12a, 12b, 12c, 13a, 13b.

In Fig. 1 a is a plan view of a trimmed security document is shown.

Shown in particular are the wave-shaped sections 20, 21 in the region of the transverse edges 19a, 19b of the trimmed security document 1. Here, it is shown that a center of the wave-shaped portions 20, 21 closer to the first longitudinal edge 18a, which forms a spine side of the security document 1, is arranged at the further longitudinal edge 18b. The wave-shaped course encodes a

Document-specific information, which is also an information present in the security document 1, in particular a serial number of the security document 1. The information may in this case be coded in particular by properties of the wavy course, e.g. a number of wave crests and troughs, a height of a wave crest and a wave trough, a width of a wave trough or a wave crest, and other imaginable features.

FIG. 2 shows a schematic block diagram of a device 14 according to the invention for producing a security document 1. The device 14 comprises an image capture device 9, a control and evaluation device 10 and a cutting device 11. Furthermore, the device 14 comprises a holding device 15 for the security document 1. In Fig. 2 it is shown that the holding device 15 is a first Holding plate 16a and a further holding plate 16b, compared to

Security document 1 have a sub-format, wherein the security document 1 between the first and the further holding plate 16a, 16b is clamped.

Before the circumcision, an image of the security document 1 is generated in the closed state by means of the image capture device 9. For this, the

Security document 1 are arranged in a detection area 17 of the image capture device 9. This can be done by means of a transport device, not shown. The security document 1 can also be transported from the detection area to the holding device 15 by means of this transport device.

By means of the image capture device 9, an image of the security document 1 is thus generated, which is then evaluated by means of the control and evaluation device 10. In this case, in particular, the previously explained format criteria can be evaluated, wherein a spatial position and a shape of a circumcision trajectory 11 are determined as a function of a result of this evaluation. In dependency of

Circumcision trajectory 1 1 and the characteristics of the circumcision trajectory 1 1, the control and evaluation device 10, the cutting device 1 1 control. In the embodiment shown in Fig. 2, the cutting device 1 1 is movable, for example, along three spatial directions of a Cartesian coordinate system. The security document 1 is stationary during the trimming process.

The cutting device 1 1 can in this case be moved in such a way that it is moved along the circumcision trajectory 11. The trimming is performed by the at least one cutting device 1 1 along the complete

Circumcision trajectory 1 1 is moved. Here, the circumcision is performed temporally and spatially along this circumcision trajectory 1 1 ongoing.

The cutting device 1 1 may be formed for example as a water jet cutting device or laser beam cutting device. Alternatively, the cutting device 1 1 may be formed as a milling or grinding device.

3 shows a schematic flow diagram of a method according to the invention. In a first step S1, a security document 1 in oversize and with a supernatant layer 6 is provided (see FIG. 1). In a second step S2, the security document 1 is arranged in oversize in a detection area 17 of an image capture device 9 (see FIG. 2). In this case, an image, in particular a two-dimensional image, of the security document 1 in oversize format is generated.

In a third step S3, an image-based evaluation of one or more format criterion / format criteria takes place, wherein a function of a result

Circumcision trajectory 1 1 is determined. In particular, a spatial position and shape of the circumcision trajectory 11 are determined.

In a fourth step S4, the security document 1 is transported to a holding device 15 (see FIG. 2) and arranged in a stationary manner by means of the holding device 15.

In a fifth step S5, the trimming is performed continuously by a cutting device 1 1 in time and space along the circumcision trajectory. Here, the cutting device 1 1 is guided spatially along the entire circumcision trajectory.

In Fig. 4 is a schematic plan view of a portion of a

Security document 1 shown.

In particular, a normal vector 22 is shown at a point of an odd section 20 of a transverse edge 19a, the normal vector 22 being oriented perpendicular to a tangent plane in the point of the section 20. It will be appreciated that this normal vector 22 includes an angle non-zero with a longitudinal axis x of the security document 1. In particular, the normal vector 22 comprises a directional component which is oriented parallel to a transverse axis y. Also, the normal vector 22 may include a directional portion oriented parallel to a vertical axis z (see, e.g., Fig. 5). However, this is not shown in Fig. 4.

5 shows a schematic longitudinal section through a security document 1.

In particular, a normal vector 23 is shown at a point of a chamfered portion 20 of a transverse edge 19a oriented perpendicular to a tangent plane in the point of the portion 20. It can be seen that this normal vector 23 with an axis x of the security document 1 encloses an angle which is not equal to zero. In particular, the normal vector 23 comprises a directional component which is oriented parallel to a vertical axis z. Also, the normal vector 23 may include a directional portion oriented parallel to a transverse axis y (see, eg, FIG. 4). However, this is not shown in Fig. 5.
