- the manufacturing process according to WO 2005/0124023 A1 is limited to authenticity features that are created by introducing a liquid substance into the banknote paper. The location of the bodies, which are acted upon by the liquid substance, is fixed by the geometry of a spray head.
- the invention has for its object to provide a manufacturing method and a manufacturing device for a multilayer security paper, which fixes the limitations of the prior art in terms of location and type of security elements.
- This device is known per se for creating holes and may already be present.
- the device for producing holes (and / or depressions) is also used for applying the security elements.
- the device produces depressions in which the individual security elements are inserted.
- the manufacturing device serves to produce a multilayer security paper. It has a first wet end, which forms a first paper web, and a second wet end, which forms a second paper web. Furthermore, a device for applying security elements to the first paper web is provided. Subordinate to this device, a Gautsch jas is provided to connect the first and the second paper web to a total paper web. Likewise, a device for producing recesses and / or holes in the first paper web is provided.
- the device for producing recesses and / or holes is used-in first variants-as the device for applying security elements.
- a device for producing recesses in the first paper web is provided in front of the device for applying security elements. It creates recesses, each recess being designed to receive one of the security elements. The recesses are spaced apart so that the security elements are applied individually and spaced apart.
- the manufacturing method comprises forming a first paper web by means of a first wet end of a paper machine and a second paper web by means of a second wet end.
- first paper web security elements are applied, and then first and second paper web are vergautscht to a total paper web.
- the security elements are applied by the device for producing holes and / or depressions themselves or introduced into recesses, which previously generated this device in the paper web.
- the first and / or second paper web may be provided with a watermark. It is also possible, in a known manner, in addition to the security elements to incorporate a security thread, a window thread or a so-called shuttle thread in the total paper web.
- security paper refers to an unprinted paper that is further processed at a later time for the production of value documents. It represents a preliminary stage for the value document.
- Value documents within the meaning of the present invention are in particular banknotes, stocks, bonds, certificates, vouchers, checks, entrance tickets, but also other counterfeit-endangered papers, such as passports and other identity documents, as well as product security elements, such as labels, seals , Packaging and the like.
- security paper or "value document” below includes all such documents and product security means.
- the security paper is multi-layered and comprises at least two layers of paper, between which lie the isolated security elements. Other layers may also be formed from paper, but also from other materials, for example by plastic films.
- the paper is preferably cotton paper as used for banknotes.
- the paper machine can be a fourdrinier machine or a round screening machine, in particular a countercurrent rotary screen machine, a DC round screening machine or a double round screening machine.
- the total paper web is preferably output as a continuous paper.
- the device for producing recesses and / or holes generates in the first variants in a first region a hole or a depression in the first paper web and at the same time applies at least one security element in a second region. As a rule, even several security elements are applied simultaneously.
- the means for creating depressions and / or holes comprises a band which is brought into contact with the first paper web.
- the tape is used - in a conventional manner - as a mask for creating the wells and / or holes.
- the recesses and / or holes are formed in the first region of the first paper web through openings in the band.
- Temporarily now security elements are applied to the tape, which are applied by the contact with the first paper web in the second area on the first paper web.
- a separation and / or lateral correct orientation of the security elements is not necessary.
- several security elements with random relative position to each other and / or different (space or side) orientation are applied.
- the plurality of security elements can thus in particular be rotated differently and / or be applied to the paper web with a different (top or bottom) side.
- the means for applying security elements brings within a benefit size several security elements on the first paper web.
- the second area may be a limited area within a utility size.
- the second area of limited area width extends over the entire utility size.
- the manufacturing device and the manufacturing process bring the security elements - in the second variants - in the wells.
- the recesses cause the positionally accurate position of the security elements on the paper web.
- the security elements are therefore not provided on a sieve layer, on a round screen, etc., and then surrounded with the material of the paper web, but subsequently introduced into an already produced paper layer.
- the wells have the nature of a blind hole.
- Each recess optionally has a rough surface to improve the adhesion between the security element and the first paper web.
- the volume of the recess in the not yet compressed first paper web i. in front of the Gautsch noise, is preferably substantially larger than the volume of the introduced security element.
- the volume of the former depression is smaller, preferably between 90 and 100% of the volume of the security element. This causes a particularly good adhesion of the security elements in the first paper web.
- the depressions can be produced particularly preferably by removing material from the first paper web again, for example by rinsing with steam or water. Such processes automatically generate an adhesion-improving surface roughness. On the other hand, they are controllable in the size of the volume produced only with limited accuracy. For this reason, it is provided in a preferred embodiment, to keep the volume of the recess larger, and to produce said Ausrichtflanke when creating the wells, for example by a suitable cutting edge or punch.
- One embodiment uses a transfer web for application.
- the isolated security elements are arranged on the transfer path.
- a transfer roller is used, which the security elements transfers from the transfer path into the depressions on the first paper web.
- Another embodiment uses at least one dispenser unit.
- the position of the dispenser unit is adjustable, so that by appropriate control of the dispenser unit, the transfer web can be equipped with security elements.
- security elements are planchettes, plaques or mottled fibers.
- the security element may be formed from paper and / or plastic, that is to say comprise, for example, a polymer film as substrate, paper as substrate, a composite substrate or polyamide fibers.
- the security elements have a machine or optically detectable property, which in particular allows an authenticity check.
- the optically detectable property can be excited by means of irradiation (UV / IR).
- the security elements are particularly preferably planar security elements.
- a benefit size is given for the security paper, according to which the total paper web is separated after production.
- the procedure according to the invention allows several, in particular an adjustable number of isolated security elements to be applied to each use.
- the security elements may differ in size and / or type.
- Fig. 1 shows schematically in plan view a banknote. It was made from a security paper, including printing.
- the bill is made from conventional banknote paper, which is usually cotton paper or cotton-containing paper.
- Two security elements 2 are embedded in the banknote paper, so they are at least partially within the banknote paper.
- the banknote 1 has been cut to a benefit derived from a web of security paper 4 on which a plurality of benefits 5 are provided, each of which is the preliminary stage for one or more banknotes 1.
- Fig. 3 schematically shows a paper machine 6 for producing the web-shaped security paper 4. It is an example of a first round screening paper machine 8 and a second round-screen paper machine 10 and has other components for supplying security elements.
- a paper web 14 is formed in a conventional manner on a round screen 12.
- This paper web 14 preferably has a grammage of 60-80 g / m 2 .
- the round screen 12 is a dewatering screen whose carrier screen is optionally provided with reliefs in the form of watermarks to be produced.
- a first paper web 16 is produced in the first round screening machine 8, for example by paper pulp being sprayed onto the surface of a round screen 20 by means of a headbox nozzle 18.
- the first paper web 16 produced with the first round screening machine 8 is optionally thinner than the second paper web and has, for example, a grammage of between 10 and 20 g / m 2 . It is removed by means of a pick-up felt 22 from the round wire 20 and a combination device, such as a couch roll 24, fed, which connects the first paper web 16 with the second paper web 14 to a total paper web 26.
- an endless security element for example in the form of a security thread 30 and embedded between the two paper webs 14, 16 when connecting.
- a combination of a depression former 32a and an application device 32b is provided, which is singulated, ie as individual pieces trained security elements on the first Paper web 16 so applied that the security elements when connecting the first paper web 16 and second paper web 14 is between the paper webs.
- the security elements are applied to the underside of the first felt 16 carried by the pick-up felt 22.
- the recess former 32a produces depressions in the paper web 16, as described below with reference to FIGS Figs. 5A and 5B will be explained.
- the recesses generated in this case are spaced apart, ie no longitudinal gaps, slots, etc. They also do not pass through the first paper web 16. Accordingly, the applicator 32b leads the security elements 2 isolated and sets them each individualized, ie spaced from other security elements, in the recesses on the first paper web 16. Various embodiments of the applicator 32b are described below with reference to Fig. 4 . 5C and 6 to 8 explained.
- the Fig. 4 and 6 relate to a first embodiment of the applicator 32.
- a supply reel 34 is provided, on which a carrier web 36 is wound, which carries a plurality of isolated security elements 2.
- the carrier web 36 is unwound from the supply reel 34 and guided by means of a deflection roller 38 to a transfer roller 40, which cooperates with a counter-roller 42.
- Transfer roller 40 and counter roller 42 form a gap through which the first paper web 16 is conveyed.
- the carrier web 36 and the paper web 16 are synchronized with each other in their movement speeds.
- the transfer roller 40 has transfer punches 44, which transfer the security elements 2 individually from the carrier web 36 into the depressions on the first paper web 16.
- the transfer roller 40 thus acts as an application device for the placement of the separated security elements on the first paper web 16, whereas the carrier web 36 acts as a supply device for feeding prepared and isolated security elements.
- the carrier web 36 from which all or some security elements have been detached, is then wound on a winding 46.
- the individual security elements are placed in the paper machine 6 directly into the first paper web 16, so not first deposited on a sieve, etc., on which then the first paper web 16 is formed.
- the applicator 32b is arranged upstream in the running direction of the first paper web 16 of the depression formers 32a. He is schematic in Fig. 5A shown. It comprises, for example, a cutting and rinsing roller 74 and a counter-roller 76, between which passes the first paper web 16 (the pick-up felt 22 against which the counter-roller 76 abuts is not shown).
- the cutting and rinsing roller 74 generates depressions 64 in the continuous first paper web 16 which are formed as receptacles for the security elements 2.
- Fig. 5B schematically shows one of the recesses 64 produced thereby. It has a rough surface 68 with a bottom 70 and a flank 72 on.
- At least one perpendicular to the conveying direction is designed as an alignment flank 66.
- the security element 2 moves when inserting into the recess 64, so that the position of the security element is precisely defined.
- the depression 64 of the volume significantly larger than the security element 2 itself, so that the security element 2 is pressed firmly and flush to the Gautsch noise 24 in the first paper web 16.
- the roughening surface 68 improves the adhesion between the material of the paper web 16 and the security element 2, in particular if it is made of a similar material, for example first paper web 16 and security element 2 both of paper.
- the insertion of the security element 2 is synchronized with the movement of the first paper web 16.
- the term "synchronized" is not limited to an absolute constant synchronization speed of the transfer belt 48 and the first paper web 16.
- the synchronization can in particular be such that the security element 2 is pressed against the alignment flank 66 acting as a stop.
- the Ausrichtflanke 66 can not only be used as a stop edge, but it can also act in the form of a driver, if it is not formed at the front edge of the recess 64, but at the trailing edge. This is in Fig. 5C illustrated by the fact that above the paper web 16 with a dashed arrow an opposite direction of travel for the first paper web is located. If the paper web 16 runs continuously in this direction, the alignment flank 66 acts as a driver, against which the application device 32b sets the security element 2.
- Fig. 5C shows the insertion process with an applicator 32b, which is schematically based on the Fig. 8 will be explained in more detail.
- the application device 32b has a carrier web 74 which rotates over a deflection roller 76, so that requested security elements 2 are delivered to the paper web 16 at a discharge station 32.
- this applicator is exemplary; the principles of insertion also apply to the other applicators described herein.
- the security element is pressed against the Ausrichtflanke 66 due to a speed surplus, which thus acts as a stop. This process is illustrated by the arrow in the recess 64. This relative movement is of course equally possible with a different applicator 32b, z. B. with transfer roller 40 with or without transfer punch 44th
- the 6 and 7 show a second embodiment of the applicator 32b.
- the security elements are not transmitted from a carrier web by means of a transfer roller but by a circulating transfer belt 48.
- the transfer belt 48 passes over deflection rollers 38 and at a speed which is synchronized with that of the first paper web 16.
- the transfer roller 40 together with the counter-roller 42, transmits the security elements to the first paper web 16.
- the transfer belt 48 is equipped by a dispenser 50 with individual security elements 2, which conveys the security elements 2 and deposits them on a transfer station 48 at a delivery station 52.
- a plurality of dispensers 50 can be used in parallel.
- the dispensers 50 are adjustable with regard to the local position of their delivery stations 52 on the transfer belt 48, so that the location at which the security elements 2 are deposited on the transfer belt 48 is controlled and adapted to the position of the recesses 64.
- Fig. 7 schematically shows an embodiment of the dispenser 50. It comprises the carrier web 54, on which the isolated security elements 2 are conveyed. The carrier web 54 is guided over the deflection rollers 56 and outputs the security elements 2 onto the transfer belt 48 at the delivery station 52.
- the dispensing location can be adjusted by means of an adjusting device 58 illustrated by a cross arrow to match the position of the depressions 64. This is controlled by a control unit 60.
- the dispenser 50 or the dispensers 50 are designed such that at least one security element 2, preferably two or more security elements, can be stored on the corresponding locations of the transfer belt 48 assigned to the utility 5 per use 5. In Fig. 7 this is illustrated schematically for an illustrated utility 5.
- the carrier web 54 may be a carrier web similar to the carrier web 36 on which the security features 2 are delivered. In contrast to the carrier web 36, however, no multi-row arrangements of security elements are provided. Alternatively it is possible by a dashed in Fig. 7 drawn dosing device 62 to equip the carrier web 54 with security elements, for example, from a stack of security elements that are pre-produced.
- Fig. 8 shows a third embodiment of the applicator 32. This is designed so that it with a dispenser 50 similar to that of 6 and 7 directly the first paper web 16 equipped with security elements 2.
- dispensers 50 generally has the advantage that the speed of the carrier web 54 may differ from the speed of the first paper web 16 (which, of course, must correspond to the speed of the transfer belt 48).
- the security elements are preferably security elements made of paper, for example planchettes or mottled fibers.
- the application of such individual paper security elements allows fibers and elements of greater titre and larger area to be used than in the conventional application of liquid phase mottling fibers such as those disclosed in the foregoing WO 2005/124023 A1 were made.
- a titer of mordant fibers of 30 dtex and greater is used.
- the means 32a for creating depressions (and / or holes) in FIG. 3 can be used in advantageous embodiments, which are not shown separately in figures, at the same time as a means for applying the security elements 32b.
- the illustration in FIG. 4 can be developed in such a way that the carrier web 36 carries the security elements in a first region and, in a second region, for example behind or in front of the illustrated cross section, the roll 40 at the same time as a hole or recess former in the sense from Fig. 5a is trained.
- the first paper web 16 is thus provided by the device simultaneously with a hole or a depression, while in another area the security elements are applied.
- a band of a (hole and / or) well former which serves as a mask for the production of holes and / or depressions by means of steam or water, for example, similar to FIG. 6 shown, temporarily provided with security elements.
- the security elements can be transferred to the band freely (any position, orientation and side). The tape comes into contact with the first paper web 16, so that in the second area the security elements are transferred from the belt to the first paper web, while at the same time through openings in the belt by means of water and / or steam at least one hole and / or recess is generated in the first paper web.

Es kann als ein gemeinsamer Gedanke der vorliegenden Erfindung betrachtet werden, eine Einrichtung zum Erzeugen von Löchern (und/ oder Vertiefungen) für weitere Schritte wieder zu verwenden. Diese Einrichtung ist für sich genommen zum Erzeugen von Löchern bekannt und gegebenenfalls bereits vorhanden. In ersten Varianten wird die Einrichtung zum Erzeugen von Löchern (und/oder Vertiefungen) auch zum Aufbringen der Sicherheitselemente verwendet. In zweiten Varianten erzeugt die Einrichtung Vertiefungen, in welche die einzelnen Sicherheitselemente eingelegt werden.It may be considered as a common idea of the present invention to reuse a means for creating holes (and / or pits) for further steps. This device is known per se for creating holes and may already be present. In first variants, the device for producing holes (and / or depressions) is also used for applying the security elements. In second variants, the device produces depressions in which the individual security elements are inserted.
Die erfindungsgemäße Herstellvorrichtung dient zur Herstellung eines mehrlagigen Sicherheitspapiers. Sie weist eine erste Nasspartie, welche eine erste Papierbahn bildet, und eine zweite Nasspartie, welche eine zweite Papierbahn bildet, auf. Weiter ist eine Einrichtung zum Aufbringen von Sicherheitselementen auf die erste Papierbahn vorgesehen. Nachgeordnet dieser Einrichtung ist eine Gautscheinrichtung vorgesehen, um die erste und die zweite Papierbahn zu einer Gesamtpapierbahn zu verbinden. Ebenso ist eine Einrichtung zum Erzeugen von Vertiefungen und/oder Löchern in der ersten Papierbahn vorgesehen.The manufacturing device according to the invention serves to produce a multilayer security paper. It has a first wet end, which forms a first paper web, and a second wet end, which forms a second paper web. Furthermore, a device for applying security elements to the first paper web is provided. Subordinate to this device, a Gautscheinrichtung is provided to connect the first and the second paper web to a total paper web. Likewise, a device for producing recesses and / or holes in the first paper web is provided.
Vorliegend wird die Einrichtung zum Erzeugen von Vertiefungen und/oder Löchern - in ersten Varianten - als die Einrichtung zum Aufbringen von Sicherheitselementen eingesetzt. In zweiten Varianten ist vor der Einrichtung zum Aufbringen von Sicherheitselementen eine Einrichtung zum Erzeugen von Vertiefungen in der ersten Papierbahn vorgesehen. Sie erzeugt Vertiefungen, wobei jede Vertiefung zur Aufnahme eines der Sicherheitselemente ausgebildet ist. Die Vertiefungen sind voneinander beabstandet, so dass die Sicherheitselemente individualisiert und voneinander beabstandet aufgebracht werden.In the present case, the device for producing recesses and / or holes is used-in first variants-as the device for applying security elements. In second variants, a device for producing recesses in the first paper web is provided in front of the device for applying security elements. It creates recesses, each recess being designed to receive one of the security elements. The recesses are spaced apart so that the security elements are applied individually and spaced apart.
Analog umfasst das Herstellverfahren das Bilden einer ersten Papierbahn mittels einer ersten Nasspartie einer Papiermaschine und einer zweiten Papierbahn mittels einer zweiten Nasspartie. Auf die erste Papierbahn werden Sicherheitselemente aufgebracht, und danach werden erste und zweite Papierbahn zu einer Gesamtpapierbahn vergautscht. Die Sicherheitselemente werden durch die Einrichtung zum Erzeugen von Löchern und/oder Vertiefungen selbst aufgebracht oder in Vertiefungen eingebracht, welche diese Einrichtung zuvor in der Papierbahn erzeugt.Similarly, the manufacturing method comprises forming a first paper web by means of a first wet end of a paper machine and a second paper web by means of a second wet end. On the first paper web security elements are applied, and then first and second paper web are vergautscht to a total paper web. The security elements are applied by the device for producing holes and / or depressions themselves or introduced into recesses, which previously generated this device in the paper web.
Bei der Herstellung kann die erste und/oder zweite Papierbahn mit einem Wasserzeichen versehen werden. Weiter ist es möglich, auf bekannte Art und Weise, zusätzlich zu den Sicherheitselementen einen Sicherheitsfaden, einen Fensterfaden oder einen sogenannten Pendelfaden in die Gesamtpapierbahn einzuarbeiten.During production, the first and / or second paper web may be provided with a watermark. It is also possible, in a known manner, in addition to the security elements to incorporate a security thread, a window thread or a so-called shuttle thread in the total paper web.
Im Sinne der Erfindung bezeichnet dabei der Begriff Sicherheitspapier ein unbedrucktes Papier, das zu einem späteren Zeitpunkt zur Herstellung von Wertdokumenten weiterverarbeitet wird. Es stellt eine Vorstufe für das Wertdokument dar. Wertdokumente im Sinne der vorliegenden Erfindung sind insbesondere Banknoten, Aktien, Anleihen, Urkunden, Gutscheine, Schecks, Eintrittskarten, aber auch andere fälschungsgefährdete Papiere, wie Pässe und sonstige Ausweisdokumente, sowie Produktsicherungselemente, wie Etiketten, Siegel, Verpackungen und dergleichen. Die vereinfachte Benennung "Sicherheitspapier" oder "Wertdokument" schließt im Folgenden alle derartigen Dokumente und Produktsicherungsmittel ein.For the purposes of the invention, the term security paper refers to an unprinted paper that is further processed at a later time for the production of value documents. It represents a preliminary stage for the value document. Value documents within the meaning of the present invention are in particular banknotes, stocks, bonds, certificates, vouchers, checks, entrance tickets, but also other counterfeit-endangered papers, such as passports and other identity documents, as well as product security elements, such as labels, seals , Packaging and the like. The simplified term "security paper" or "value document" below includes all such documents and product security means.
Das Sicherheitspapier ist mehrlagig ausgebildet und umfasst mindestens zwei Lagen Papier, zwischen denen die vereinzelten Sicherheitselemente liegen. Weitere Lagen können ebenfalls aus Papier, aber auch aus anderen Materialien, beispielsweise durch Kunststofffolien, gebildet sein. Das Papier ist bevorzugt Baumwollpapier, wie es für Banknoten verwendet wird. Bei der Papiermaschine kann es sich um eine Langsiebmaschine oder eine Rundsiebmaschine, insbesondere eine Gegenstromrundsiebmaschine, eine Gleichstromrundsiebmaschine oder eine Doppelrundsiebmaschine, handeln. Die Gesamtpapierbahn wird vorzugsweise als Endlospapier ausgegeben.The security paper is multi-layered and comprises at least two layers of paper, between which lie the isolated security elements. Other layers may also be formed from paper, but also from other materials, for example by plastic films. The paper is preferably cotton paper as used for banknotes. The paper machine can be a fourdrinier machine or a round screening machine, in particular a countercurrent rotary screen machine, a DC round screening machine or a double round screening machine. The total paper web is preferably output as a continuous paper.
Die Einrichtung zum Erzeugen von Vertiefungen und/oder Löchern erzeugt in den ersten Varianten in einem ersten Bereich ein Loch oder eine Vertiefung in der ersten Papierbahn und bringt gleichzeitig in einem zweiten Bereich mindestens ein Sicherheitselement auf. In der Regel werden dabei sogar mehrere Sicherheitselemente gleichzeitig aufgebracht.The device for producing recesses and / or holes generates in the first variants in a first region a hole or a depression in the first paper web and at the same time applies at least one security element in a second region. As a rule, even several security elements are applied simultaneously.
Die Einrichtung zum Erzeugen von Vertiefungen und/oder Löchern umfasst ein Band, welches mit der ersten Papierbahn in Kontakt gebracht wird. Das Band wird - in an sich bekannter Form - als Maske zur Erzeugung der Vertiefungen und/oder Löcher verwendet. Insbesondere werden durch Öffnungen in dem Band hindurch die Vertiefungen und/oder Löcher im ersten Bereich der ersten Papierbahn ausgebildet. Temporär werden nun Sicherheitselemente auf das Band aufgebracht, welche durch den Kontakt mit der ersten Papierbahn in dem zweiten Bereich auf die erste Papierbahn aufgebracht werden. Insbesondere ist dabei eine Vereinzelung und/oder seitenrichtige Orientierung der Sicherheitselemente nicht nötig. Bevorzugt werden mehrere Sicherheitselemente mit zufälliger Relativposition zueinander und/oder unterschiedlicher (Raum- bzw. Seiten-) Orientierung aufgebracht. Die mehreren Sicherheitselemente können also insbesondere unterschiedlich gedreht sein und/oder mit einer unterschiedlichen (Ober- oder Unter-) Seite zur Papierbahn aufgebracht werden.The means for creating depressions and / or holes comprises a band which is brought into contact with the first paper web. The tape is used - in a conventional manner - as a mask for creating the wells and / or holes. In particular, the recesses and / or holes are formed in the first region of the first paper web through openings in the band. Temporarily now security elements are applied to the tape, which are applied by the contact with the first paper web in the second area on the first paper web. In particular, a separation and / or lateral correct orientation of the security elements is not necessary. Preferably, several security elements with random relative position to each other and / or different (space or side) orientation are applied. The plurality of security elements can thus in particular be rotated differently and / or be applied to the paper web with a different (top or bottom) side.
Die Einrichtung zum Aufbringen von Sicherheitselementen bringt innerhalb einer Nutzengröße mehrere Sicherheitselemente auf die erste Papierbahn auf. Insbesondere kann der zweite Bereich eine begrenzte Fläche innerhalb einer Nutzengröße sein. Alternativ erstreckt sich der zweite Bereich mit begrenzter Bereichsbreite über die ganze Nutzengröße.The means for applying security elements brings within a benefit size several security elements on the first paper web. In particular, the second area may be a limited area within a utility size. Alternatively, the second area of limited area width extends over the entire utility size.
Die Herstellvorrichtung und das Herstellverfahren bringen die Sicherheitselemente - in den zweiten Varianten - in die Vertiefungen auf. Die Vertiefungen bewirken die positionsgenaue Lage der Sicherheitselemente auf der Papierbahn. Die Sicherheitselemente werden also nicht auf einer Sieblage, auf einem Rundsieb etc. vorgesehen und dann mit dem Material der Papierbahn umgeben, sondern nachträglich in eine bereits erzeugte Papierlage eingebracht. Die Vertiefungen haben dabei die Art eines Sacklochs.The manufacturing device and the manufacturing process bring the security elements - in the second variants - in the wells. The recesses cause the positionally accurate position of the security elements on the paper web. The security elements are therefore not provided on a sieve layer, on a round screen, etc., and then surrounded with the material of the paper web, but subsequently introduced into an already produced paper layer. The wells have the nature of a blind hole.
Jede Vertiefung hat optional eine Rauhfläche zur Haftungsverbesserung zwischen dem Sicherheitselement und der ersten Papierbahn.Each recess optionally has a rough surface to improve the adhesion between the security element and the first paper web.
Das Volumen der Vertiefung in der noch nicht komprimierten ersten Papierbahn, d.h. vor der Gautscheinrichtung, ist bevorzugt wesentlich größer als das Volumen des einzubringenden Sicherheitselementes. Nach der Kompression in der Gautscheinrichtung ist hingegen das Volumen der ehemaligen Vertiefung kleiner, bevorzugt zwischen 90 und 100 % des Volumens des Sicherheitselementes. Dies bewirkt eine besonders gute Haftung der Sicherheitselemente in der ersten Papierbahn.The volume of the recess in the not yet compressed first paper web, i. in front of the Gautscheinrichtung, is preferably substantially larger than the volume of the introduced security element. After compression in the Gautscheinrichtung, however, the volume of the former depression is smaller, preferably between 90 and 100% of the volume of the security element. This causes a particularly good adhesion of the security elements in the first paper web.
Insbesondere aber nicht ausschließlich für den Fall einer Vertiefung, die erheblich größer ist, als das Sicherheitselement, ist es zu bevorzugen, eine Ausrichtung des Sicherheitselementes an der Papierbahn und im vergleichsweise größeren Sackloch vorzusehen, indem jede Vertiefung eine im Wesentlichen senkrecht, z. B. zwischen 80° und 100°, zur Oberfläche der ersten Papierbahn und im Wesentlichen senkrecht, z. B. zwischen 80° und 100°, zu einer Förderrichtung der ersten Papierbahn verlaufende Ausrichtrichtflanke hat, die als Mitnehmer- oder Anschlagflanke beim Einsetzen des Sicherheitselementes wirkt. Das Sicherheitselement wird dann beim Ansetzen auf diese Ausrichtflanke hingedrückt, so dass eine präzise Lage im eigentlich größeren Volumen der Vertiefung gesichert ist. Auf der Papierbahn und insbesondere in einem späteren Nutzen, der nach der Vereinzelung der Papierbahn anfällt, sehr präzise einstellbar. Auch mehrere solche Flanken sind möglich.In particular, but not exclusively in the case of a recess which is considerably larger than the security element, it is preferable to align the security element on the paper web and in comparison provide larger blind hole by each well a substantially vertical, z. B. between 80 ° and 100 °, to the surface of the first paper web and substantially perpendicular, z. B. between 80 ° and 100 °, to a conveying direction of the first paper web extending Ausrichtrichtflanke which acts as a driver or stop edge at the onset of the security element. The security element is then pressed during attachment to this Ausrichtflanke, so that a precise position in the actually larger volume of the recess is secured. On the web and in particular in a later benefit that arises after the separation of the paper web, very precisely adjustable. Several such flanks are possible.
Die Vertiefungen können besonders bevorzugt erzeugt werden, indem aus der ersten Papierbahn wieder Material entfernt wird, beispielsweise durch Ausspülen mit Dampf oder Wasser. Solche Prozesse erzeugen automatisch eine haftungsverbessernde Rauhfläche. Sie sind andererseits in der Größe des erzeugten Volumens nur mit begrenzter Genauigkeit steuerbar. Aus diesem Grund ist es in einer bevorzugten Ausführungsform vorgesehen, das Volumen der Vertiefung größer zu halten, und beim Erzeugen der Vertiefungen die genannte Ausrichtflanke herzustellen, beispielsweise durch eine geeignete Schneide oder Stanze.The depressions can be produced particularly preferably by removing material from the first paper web again, for example by rinsing with steam or water. Such processes automatically generate an adhesion-improving surface roughness. On the other hand, they are controllable in the size of the volume produced only with limited accuracy. For this reason, it is provided in a preferred embodiment, to keep the volume of the recess larger, and to produce said Ausrichtflanke when creating the wells, for example by a suitable cutting edge or punch.
Das Aufbringen der Sicherheitselemente ist durch die Aufnahme in Form der Vertiefung erheblich erleichtert. Es kommen deshalb insbesondere verschiedene Varianten zum Aufbringen in Frage.The application of the security elements is greatly facilitated by the inclusion in the form of the depression. There are therefore in particular different variants for application in question.
Eine Ausführungsform verwendet zum Aufbringen eine Transferbahn. Auf der Transferbahn sind die vereinzelten Sicherheitselemente angeordnet. Als Aufbringeinrichtung wird eine Transferwalze eingesetzt, welche die Sicherheitselemente von der Transferbahn in die Vertiefungen auf der ersten Papierbahn überträgt.One embodiment uses a transfer web for application. On the transfer path, the isolated security elements are arranged. As application device, a transfer roller is used, which the security elements transfers from the transfer path into the depressions on the first paper web.
Eine andere Ausführungsform verwendet mindestens eine Spendereinheit. Die Lage der Spendereinheit ist verstellbar, so dass durch entsprechende Einsteuerung der Spendereinheit die Transferbahn mit Sicherheitselementen bestückt werden kann.Another embodiment uses at least one dispenser unit. The position of the dispenser unit is adjustable, so that by appropriate control of the dispenser unit, the transfer web can be equipped with security elements.
Beispiele für Sicherheitselemente sind Planchetten, Plaketten oder Melierfasern. Das Sicherheitselement kann aus Papier und/oder Kunststoff gebildet sein, also beispielsweise ein eine Polymerfolie als Substrat, Papier als Substrat ein Verbundsubstrat oder Polyamidfasern umfassen. Die Sicherheitselemente weisen eine maschinell oder optisch erfassbare Eigenschaft auf, welche insbesondere eine Echtheitsprüfung ermöglicht. Die optisch erfassbare Eigenschaft kann mittels Bestrahlung (UV/IR) angeregt werden. Besonders bevorzugt sind die Sicherheitselemente flächige Sicherheitselemente.Examples of security elements are planchettes, plaques or mottled fibers. The security element may be formed from paper and / or plastic, that is to say comprise, for example, a polymer film as substrate, paper as substrate, a composite substrate or polyamide fibers. The security elements have a machine or optically detectable property, which in particular allows an authenticity check. The optically detectable property can be excited by means of irradiation (UV / IR). The security elements are particularly preferably planar security elements.
Üblicherweise ist für das Sicherheitspapier eine Nutzengröße vorgegeben, dergemäß die Gesamtpapierbahn nach der Herstellung vereinzelt wird. Das erfindungsgemäße Vorgehen erlaubt es, auf jedem Nutzen mehrere, insbesondere eine einstellbare Anzahl an vereinzelten Sicherheitselementen aufzubringen. Auch können die Sicherheitselemente sich in Größe und/oder Art unterscheiden.Usually, a benefit size is given for the security paper, according to which the total paper web is separated after production. The procedure according to the invention allows several, in particular an adjustable number of isolated security elements to be applied to each use. Also, the security elements may differ in size and / or type.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Zeichnungen, die ebenfalls erfindungswesentliche Merkmale offenbaren, noch näher erläutert. Diese Ausführungsbeispiele dienen lediglich der Veranschaulichung und sind nicht als einschränkend auszulegen.

Die folgende Figurenbeschreibung ist eher auf die Varianten ausgerichtet, in welchen Vertiefungen für die Sicherheitselemente erzeugt werden. Die Varianten, in denen eine Einrichtung zum Erzeugen der Vertiefungen (und/ oder Löcher) zugleich auch zum Aufbringen der Sicherheitselemente dient, wird dagegen am Ende der Figurenbeschreibung näher erläutert.The following description of the figures is aimed more at the variants in which recesses are created for the security elements. The variants in which a device for generating the recesses (and / or holes) at the same time also serves for applying the security elements, however, is explained in more detail at the end of the description of the figures.
In der zweiten Rundsiebmaschine 10, die vorzugsweise als Gleichstromrundsiebmaschine ausgebildet ist, wird auf an sich bekannte Weise auf einem Rundsieb 12 eine Papierbahn 14 gebildet. Diese Papierbahn 14 weist vorzugsweise eine Grammatur von 60 - 80 g/m2 auf. Das Rundsieb 12 ist ein Entwässerungssieb, dessen Trägersieb optional mit Reliefs in Form von zu erzeugenden Wasserzeichen versehen ist. Parallel zur Herstellung der ersten Papierbahn 14 wird in der ersten Rundsiebmaschine 8 eine erste Papierbahn 16 hergestellt, beispielsweise indem Papiermasse mittels einer Stoffauflaufdüse 18 auf die Oberfläche eines Rundsiebs 20 aufgedüst wird. Die mit der ersten Rundsiebmaschine 8 erzeugte erste Papierbahn 16 ist optional dünner als die zweite Papierbahn und weist beispielsweise eine Grammatur zwischen 10 - 20 g/m2 auf. Sie wird mittels eines Abnahmefilzes 22 vom Rundsieb 20 abgenommen und einer Vereinigungseinrichtung, beispielsweise einer Gautschwalze 24, zugeführt, welche die erste Papierbahn 16 mit der zweiten Papierbahn 14 zu einer Gesamtpapierbahn 26 verbindet.In the second Rundsiebmaschine 10, which is preferably designed as Gleichstromrundsiebmaschine, a
Beim Zusammenführen der Papierbahnen 14,16 wird zudem von einer Spule 28 ein endloses Sicherheitselement, beispielsweise in Form eines Sicherheitsfadens 30 abgespult und zwischen die beiden Papierbahnen 14, 16 beim Verbinden eingebettet.When merging the
Weiter ist zwischen der ersten Rundsiebmaschine 8, d. h. nach Erzeugen der ersten Papierbahn 16 in der Nassphase und vor dem Verbinden der ersten und zweiten Papierbahn 14, 16, eine Kombination aus einem Vertiefungsformer 32a und einer Aufbringeinrichtung 32b vorgesehen, welche vereinzelte, d. h. als individuelle Stücke ausgebildete Sicherheitselemente auf die erste Papierbahn 16 so aufbringt, dass die Sicherheitselemente beim Verbinden von erster Papierbahn 16 und zweiter Papierbahn 14 zwischen den Papierbahnen liegt. In der Darstellung der

Das Einsetzen des Sicherheitselementes 2 geschieht synchronisiert zur Bewegung der ersten Papierbahn 16. Der Begriff "synchronisiert" ist dabei nicht auf eine absolute konstante Gleichlaufgeschwindigkeit von Transferband 48 und erster Papierbahn 16 eingeschränkt. Die Synchronisierung kann insbesondere so erfolgen, dass das Sicherheitselement 2 an die als Anschlag wirkende Ausrichtflanke 66 gedrückt wird. Die Ausrichtflanke 66 kann jedoch nicht nur als Anschlagflanke eingesetzt werden, vielmehr kann sie auch in Form eines Mitnehmers wirken, wenn sie nämlich nicht an der vorderen Kante der Vertiefung 64 ausgebildet wird, sondern am nachlaufenden Rand. Dies ist in

Bei der Trägerbahn 54 kann es sich um eine Trägerbahn ähnlich der Trägerbahn 36 handeln, auf der die Sicherheitsmerkmale 2 angeliefert werden. Im Unterschied zur Trägerbahn 36 sind jedoch keine mehrreihigen Anordnungen von Sicherheitselementen vorgesehen. Alternativ ist es möglich, durch eine gestrichelte in
