Description

The present invention relates to a method and a corresponding device for producing a security document.

Security documents, such as identity cards, passports and the like, consist of a plurality of layers interconnected by a lamination process. In addition to the pressure layers for a front and a back and corresponding front and back laminating other layers, for example, for holographic or other security features may be provided.

The print layers for a front and back are usually printed with multiple "benefits". By this is meant that for cost and efficiency reasons, several copies of a printed product, so-called "benefits", arranged on a sheet and these are separated later in a cutting machine into individual benefits. The cutting process is usually done in shock, d. H. a variety of front side and back side stitches are cut as a push. Especially with security documents but very high demands are placed on precision and dimensional accuracy.

From the DE 10 2007 053 203 A1 For example, a method for producing a laminate card and a laminate card consisting of several layers is known. To produce this laminate card, multi-use sheets are provided, each of these sheets having centering holes, so that when the sheets are stacked by means of the centering holes, the sheets are aligned with each other.

From the DE 10 2006 037 432 A1 a method for producing at least one window opening in an elongate paper substrate is known, wherein the paper substrate is provided with at least one watermark per paper section, which is detectable by means of a sensor. Subsequently, depending on the detected position of the watermark, at least one window opening is produced in the paper substrate. Subsequently, the individual benefits for further processing with other layers are isolated.

The invention has for its object to provide a method and a corresponding device for producing a security document, with which a high precision and dimensional accuracy is achieved, which on the other hand but works reliably and efficiently.

The object is achieved with regard to the method by the features of claim 1 and with respect to the device by the features of claim 10. Advantageous embodiments can be found in the dependent claims.

According to the invention, to produce a security document consisting of several layers, first of all printing layers for a front side and a back side are provided with multiple benefits on respective printed sheets. The printing layers for the front and the back are carried together with at least one other layer to front and back pages together and stapled to form a layer composite. The front and back pages are then individually aligned and recessed, with the recesses placed in trimming areas. Subsequently, the layer composite is assembled from in each case a front side booklet, an associated back side booklet and at least one intermediate layer, the front side booklet and the back booklet being positioned relative to each other on the basis of the openings. Under heat and / or pressure, the layers are laminated to form a laminated composite. Subsequently, the laminate composite is trimmed in at least one cutting operation and the benefits that may constitute the security document or are part of a security document are isolated.

The fact that the individual pressure layers are aligned and cut separately, a higher precision compared to a cutting operation of the combined front or rear side books is achieved in the shock. The recesses allow accurate positioning of the front and back booklets to each other.

Preferably, together with the step of attaching the recesses, a check is made for the presence of all the layers provided for the front side or back side stitch by means of a thickness measurement. As a result, an improved quality assurance is achieved by early detection of defective front and back pages and sorted out.

The alignment of the front and back pages for the subsequent introduction of the recesses each separated into the front side and the back side booklet is preferably carried out on the basis of positioning marks each contained on the printing layers. This also contributes to improved precision in mounting the recesses.

The composite layer of the front and back side booklet can be inserted for the lamination in a lamination cassette, in which this is preferably aligned on the basis of the recesses. When laminating the layer composite to a laminate composite in which the individual layers and / or the front side and the back side are at least partially glued or welded together, preferably at least one closed peripheral edge of the respective benefit is formed, at the same time a characteristic structuring as a security feature in the surfaces of the Laminate composite be embossed. This can be done very precisely in this step, which leads to improved security against counterfeiting.

Preferably, together with the step of attaching the recesses, a trimming of the front side or rear side booklet takes place along a first edge. Again, the individual positioning of the front and back covers has an advantageous effect on the cutting accuracy. In addition, combining several operations into one cutting step increases manufacturing efficiency.

If the liner is beyond the first pruned edge of the front and back side, respectively, it may be used to advantage to form a tab for later sewing into a passport book.

If the covers of the passbooks and possibly their insides are provided as a double benefit, tailored to double benefit, formed from a laminate composite benefits, especially trained as Personalisierdatenseite security document, sewn together and then isolated. This in turn saves a step, since two benefits are sewn in one operation.

Together with the step of attaching the recesses, a first blank for halving the front side or back side booklet and simultaneously trimming along a first edge of the benefit formed from a laminate composite can already take place. In this way, several steps can be summarized again and at the same time a high cutting accuracy can be achieved by the individual positioning of the front and back pages.

If, prior to lamination, a preferably antistatic cleaning of the tops of the front and back pages of dust particles takes place, the manufacturing quality is improved and the rejects reduced.

In an apparatus for producing a multi-ply security document according to one of the methods of the present invention, an optical positioning aid or automated positioning device for aligning a ply composite of a front or back side stack is preferably a tool based on at least two positioning marks contained on a print ply a punching tool, for mounting recesses in edge regions of the aligned layer composite of the front or back side stitching and a measuring device for automated thickness measurement of the aligned front or back side stitch.

The device allows a precise, automated and thus efficient production of security documents according to the inventive method.

Preferably, the apparatus further comprises a cutting tool, preferably a slitter, for automated trimming of the aligned front or back side along at least one cutting line. This can be summarized several operations and thus increase the efficiency.

In addition, a cleaning device for preferably antistatic cleaning of the staple tops of dust particles can be provided. This can improve the manufacturing quality and reduce the rejects.

The invention and further advantageous embodiments and developments thereof are described in more detail below with reference to the examples shown in the drawings and explained. The features to be taken from the description and the drawings can be applied individually according to the invention individually or in combination in any combination. Show it:

1a -J an overview of the individual production steps of a security document and

2 A second embodiment of a layer association of an ID card in the 20s benefit.

In the 1a to 1j the individual stages of production are shown in a first embodiment of a method according to the invention. First, an in 1a illustrated pressure position 10 provided a sheet with, for example, eight benefits 20 for security documents 51 contains. The pressure situation 10 is therefore referred to as a benefit of 8.

The security documents 51 may be formed as an ID1 format and be, for example, a bank card, credit card, driver's license or electronic identity card as well as any other admission card ( 2 ). Furthermore, the security documents can be used as data page, in particular personalization data page of a passport, be provided in an ID3 format ( 1j ).

That in the 1a to 1j For example, the manufacturing method described relates to a security document 51 , which is provided as Personalisierdatenseite for a passport, especially an electronic passport.

Because the security documents 51 each have a printed front and a printed back, it may be in the 8-use to a sheet 10 with either document front pages or backs, which are processed separately here first.

In a second step, as in 1b shown to the pressure position 10 more layers 11 . 11 ' . 12 . 12 ' added. This at least one more location 11 includes at least one laminating film applied to the printing sheet 10 is applied, and preferably further optional layers or films. This can be a location, for example 11 ' be, the other security features, such. Holograms, security threads or the like, or contains data and information about the document holder. The location 11 may additionally or alternatively also contain a photosensitive layer for later imprinting a hologram by means of laser holography. Alternatively, the layers can 11 and the at least one location 11 ' to be united in one situation. In addition, optionally one or more layers 12 . 12 ' as liners on the bottom and / or top of the sheet 10 may be added, for example, serve as Zwischenlaminatschichten and may contain other security features.

Which additional layers are provided exactly depends on the respective security document to be produced. It is essential, however, that the pressure situation 10 each separately for the production of a front page booklet 30 and a back booklet 31 one or more additional layers 11 . 11 ' . 12 . 12 ' , including at least one laminate layer 11 , to be added.

The layers 10 . 11 . 11 ' . 12 . 12 ' become a front and back booklet 30 . 31 , as in 1c shown on a work table 15 in a stitching station 17 put on and by single stapling points 35 ( 1f ) stapled together. This is done with a tool 16 , which under selective heat and / or pressure the layers 10 . 11 . 12 at the individual stapling points 35 welded together. So arises from a sheet 10 with other layers 11 . 12 a layer composite 18 for a front page booklet 30 and accordingly from a printed sheet 10 with other layers 11 . 12 a layer composite 18 for a backsheet 31 ,

In the next step, each one is individually from the front and back pages 30 . 31 semicircular recesses 22 cut out. These are the front and / or back cover 30 . 31 on the basis of the printed image of the printing position 10 located positioning marks 21 aligned with respect to a cutting tool. The alignment can be done by means of an optical positioning aid or an automatic positioning device, for. B. with the aid of a laser pointer or a laser scanner, done manually or automatically. In the present example, four positioning marks 21 included on an 8-pack that allows for safe and accurate alignment. Aligning would of course already possible with two positioning marks.

For cutting out the recesses 22 is particularly suitable punching tool. The recesses 22 even become in trim areas 47 attached, which are separated in later processing steps.

In the present embodiment are in each front and back cover 30 . 31 a total of six recesses 22 punched, four at the in the 1d bottom edge and two at the top edge. The recesses 22 serve on the one hand to the front and back pages 30 . 31 later in a laminating cassette 37 ( 1h ), and on the other hand, to the front pages 30 and back pages 31 to position each other. The recesses 22 are therefore preferably arranged mirror-symmetrically, so that a front page booklet 30 and a back page 31 with the same recesses 22 Nevertheless, they can be congruently superimposed in opposite directions.

The front and back handle 30 . 31 is still in the 8-benefit, so with eight benefits 20 , as a prefixed layer composite 18 in front. Together with the attachment of the recesses 22 becomes the front and back tack 30 . 31 now along the cutting lines 23 - 26 cut. The cut lines 23 and 26 thereby run along with respect to the pressure position 10 outer longitudinal edges of the benefits 20 , The cut lines 24 and 25 run along from the center of the pressure 10 oriented longitudinal edges of the benefits 20 and divide the 8's benefit into two 4's 27 . 28 according to 1e , The cuts preferably take place with a roll cutting tool.

Due to the individual alignment of the individual front and back pages 30 . 31 In this case, a very high accuracy is achieved when cutting especially against processing in the impact. The cutting process along the cutting lines 23 - 26 and punching out the recesses 22 is preferably automated by a suitable cutting and punching machine in a common processing step.

Preferably also takes place together with the cutting or punching of the front and back side booklet 30 . 31 a thickness measurement, which serves as a check, whether all intended positions 10 . 11 . 11 ' . 12 . 12 ' the front and back side booklet 30 . 31 available. Thickness measurement can also be automated in the same processing step. For thickness measurement, for example, an optical distance meter or a sensor can be used, which on the cutting and punching machine, with the recesses 22 are punched, are provided. Deviations from a target thickness lead to the front and back side tack 30 . 31 is declared deficient and rejected. By combining punching, cutting and thickness measurement in an automated process, a production step is saved.

In 1e are the cut-4s-benefits 27 and 28 front and back booklet 30 . 31 shown. At theirs regarding the 4s benefit 27 . 28 outward-facing longitudinal edges are the individual benefits 20 already cropped to her later girth. The recesses 22 are at both 4-utility 27 . 28 congruent.

In the next production step, as in 1f shown, for example, the 4-he benefits 27 . 28 as a front page booklet 30 , as a back page 31 as well as an intermediate layer 32 collected. The liner 32 serves as an intermediate laminate layer for the following lamination process. Preferably, the intermediate layer exists 32 from a composite of cellulose fibers called a prelaminate and a laminatable thermoplastic such as polycarbonate (PC), polyethylene terephthalate (PET), or polyvinyl chloride (PVC).

In the exemplary embodiment, the intermediate layer 32 also one over the two end-trimmed sides of the front and back pages 30 . 31 protruding supernatant 34 on. This later serves to form a tab with which the security document formed as a personalization data page 51 sewn into a passport book.

The front page booklet 30 and the back page 31 be with their outward facing pressure layers 10 placed on top of each other so that the recesses 22 match congruently. The liner 32 , on whose exact positioning it does not matter, is slightly narrower, so they have the recesses 22 not covered. The liner 32 However, it protrudes at the edge adjacent to the cutouts 22 into later trim areas 47 into it.

In 1f are also the stapling points 35 indicated with which the individual layers to form the composite layer 18 for the front and back pages 30 . 31 each connected. The stapling points 35 are preferably also in trim areas 47 which will be separated later.

The 1g shows the stack of front page booklet 30 , Liner 32 and backside booklet 31 according to 1f in a side view. The supernatant 34 the liner 32 sticks out again laterally over the front and back pages 30 . 31 out to form the later tab.

In the next manufacturing step, the lamination process now takes place. 1h shows, as to the stack of front page booklet 30 , Liner 32 and backside booklet 31 in a laminating cassette 37 inserted and the laminating cassette 37 then with a cover plate 38 is closed. Lateral mechanical positioning aids 39 , for example in the form of guide pins, engage in the recesses 22 in the front and back side 30 . 31 and position them in the laminating cassette 37 , In addition, the positioning aids 39 the cover plate 38 , The laminating cassette 37 is now introduced into a laminating press in which the stack under the action of heat and / or pressure to an inseparable laminate composite 40 is welded.

Preferably, the bottom of the laminating cassette 37 and / or the cover plate 38 each a characteristic structuring, which leaves as a further security feature impressions in the surface of the laminated security document. Due to the precise fixing of the front and back pages 30 . 31 in the laminating cassette, the structures embossed in this way can be applied with very high accuracy, which increases the security against counterfeiting.

Before the front and back side 30 . 31 in the laminating cassette 37 In addition, a cleaning step can be done to the front and back pages 30 . 31 from paper dust that inevitably results from the cutting process. For example, in the cutting and punching machine, which the recesses 22 punches and cuts 23 - 26 An antistatic unit may be provided which performs antistatic cleaning, for example by spraying with an antistatic agent. In addition to or as an alternative to an antistatic unit, it is also possible to provide further cleaning devices, such as antistatic brushes or a dust extraction.

Next, as in 1i shown along the cutting lines 41 - 46 a trimming of the laminate composite 40 carried out. Through the cuts 41 . 42 the upper and lower trim areas are omitted 47 with the recesses 22 , The cuts 44 and 45 separate the 4-up into two double-cuts, and the cuts 43 and 46 shorten the supernatant 34 on the tab 34 Needed for sewing measure. The trimming is preferably done for all cuts 41 to 46 at the same time and especially for all cuts 41 - 46 to the final dimension of the four security documents, based on the positioning marks 21 is aligned. Preferably, a reel cutter is used for this purpose again.

Through the cuts along the cutting lines 41 - 46 will be two double benefits 48 educated. These security documents, which are available as double benefits 51 are now sewn in also provided as a double benefit bindings passbooks and then separated by a final separation cut. Alternatively, the dual benefits can also be isolated so that the individual security documents 51 available.

The 2 shows another embodiment, which relates to the production of security documents in ID1 format, such as check cards, credit cards, driver's licenses or the like.

The presentation of the 2 corresponds in analogy to the manufacturing method described above the 1i , To produce such security documents is also a printing layer 10 with at least one other location 11 . 11 ' , in particular film and / or position 12 . 12 ' , to a front page and a back page 30 . 31 worn together, as in 1b is shown. These are then analogously to 1c stapled to each other. Subsequently, according to 1d only the recesses 22 brought in. The introduction of further cuts, as to the 1d and 1e has been described, can be omitted in this embodiment. Subsequently, the front page booklet 30 , the back side 31 and the intermediate laminate layer 32 positioned to each other, these preferably congruent with the release of the recesses 22 to be positioned to a stack. Subsequently, in the laminator, the production of a laminate composite 40 now, as in 2 is shown, is cut. This laminate composite 40 will be at the positioning marks 21 aligned and initially along the cutting lines 55 . 56 and 57 cut so that two 10's are made. Then these two 10's will turn on the positioning marks 21 geared to following the individual benefits 20 punch out, so that the finished punched out security documents 51 available.

Alternatively, the intermediate step of separating the 20's benefit into a 10's benefit may be omitted.

All of the features described above are essential to the invention and can be combined with one another as desired.
