Definitions
- the invention relates to a method for producing a data card for a security document and an ultrasonic punching tool.
- this book-like document which is shown in FIG. 10a, comprises a first and at least one further layer made of a polymer laminate layer.
- a carrier layer with a microchip is provided between the layers.
- the laminate layers have an outer, peripheral, closed edge, by which the carrier layer is completely enclosed and embedded between the layers.
- the laminate layers are made by a roll lamination or an embossing press process. After forming the laminate layer wrapper by the at least two laminate layers, the edges are trimmed to subsequently wrap the laminate layer wrapper with a cover material.
- a method for producing a laminate composite is also known.
- a front booklet and back booklet consisting of several layers as well as an intermediate layer positioned in between are placed in a laminating cassette and then welded to form a laminate composite.
- This laminate composite is then trimmed, so that individual data cards are provided from this laminate composite, which are trimmed to a final size by the trimming.
- a method for producing a composite body for a document type selected from a plurality of different types of identification, value or security documents In this process, a selection of document-type-specific material sheets is collected in order to laminate them into a composite body. Subsequently, the composite body is ultrasonically processed to a desired one Format.
- the composite body of sheets of material is cut to size by wedge cutting using an ultrasonic knife.
- the ultrasonic knife designed as a sonotrode includes a peripheral edge, the course of which corresponds to the circumference of the geometric format.
- the melting of the material sheet booklet in the area of the cut by ultrasound leads to a sealing of the resulting cut surface. The individual layers are no longer identifiable, which increases the security of the document.
- the data card is complete.
- a system and a method for producing an identification, value or security document is known.
- a cutting knife with a sonotrode is used, which has a circumferential cutting edge, the course of which corresponds to a circumference of the geometric format of the document body to be produced.
- the invention is based on the object of proposing a method for producing a data card from a raw card and an ultrasonic punching tool, which increases security against forgery.
- This object is achieved by a method for producing the data card for a security document, in which several layers are aligned with one another and laminated in a laminating process to form a laminate composite and are cut to a final size, so that a raw card is produced as a laminate composite, the final size cut raw card is laminated with at least one film made of a thermoplastic elastomer and one, several or all front edges of the film extend beyond the raw card and that the film protruding beyond the final dimension of the raw card is cut to the final dimension of the raw card by ultrasonic punching with a processing tool and the at least one end face of the film laminated on and the at least one end face of the raw card are sealed to one another.
- This procedure allows the raw card for example, personalized in a printing station and then laminated with a film to form a data card, with only the at least one laminated film being cut to the format that corresponds to the raw card that has already been cut to the final dimensions and provided. At the same time, the edge of the at least one end face of the film is sealed in the corresponding end face of the raw card. Separation or splitting as well as detachment of the laminated film is made more difficult, which increases the security of the data card against forgery.
- the format of the data card can be, for example, an ID1 format, such as a bank card, credit card, driver's license or an electronic identity card, as well as other access cards.
- an ID3 format can also be punched, for example to produce a personal data page of a passport.
- Other formats are also possible.
- the end faces of the raw card are processed with the end faces of the film laminated on with an inner sealing surface adjoining the peripheral cutting edge.
- an inner sealing surface adjoining the peripheral cutting edge.
- ID1 or ID3 documents or other security documents for example, can be produced with short cycle times.
- the protection against counterfeiting is increased by the sealed edge area of the data card.
- the raw card cut to the final size is preferably laminated with the at least one layer or film made of a thermoplastic elastomer, with the layer made of thermoplastic elastomer preferably protruding beyond all front edges of the raw card and the layer protruding beyond the raw card being cut to the final size of the raw card with the processing tool and the edge area of the data card is sealed.
- the raw card itself is no longer cut to a final size, but only the at least one layer laminated thereto and the end faces of the raw card cut to final size are sealed together with the end faces of the at least one laminated layer.
- an edge rounding is applied to the laminated film.
- the outer peripheral edge of the film, which is formed by ultrasonic punching, is at least deburred, preferably rounded. This can improve the feel of the data card.
- a further preferred embodiment of the method provides that the raw card cut to the final size and the at least one film laminated thereon, which extends beyond the final size of the raw card, is cut with the processing tool by ultrasonic punching, in which a Shoulder connects, which points towards the middle of the data card, through which a peripheral edge of the data card is rounded and the end face of the at least one laminated layer is sealed to the end faces of the raw card. Additional pressure on the edge of the data card can be achieved by this shoulder in the processing tool in order to securely connect the at least one further layer laminated on the raw card and to ensure the sealing of the end faces with the adjacent end faces of the raw card.
- a further preferred embodiment of the method provides that the laminated and preferably previously printed raw card is positioned on an anvil whose support surface corresponds to the final dimensions of the raw card and opposite a counter anvil with its support surface the contact surface of the anvil is moved to a working level in which the support surface rests against the laminated film and the processing tool is then advanced onto the counter anvil. This makes it possible for the film laminated onto the raw card to be trimmed exactly.
- an edge region of the film protruding beyond the final dimension of the raw card is separated by at least one additional blade during the sealing of the end face of the film to the end face of the raw card. This allows for easy disposal of the supernatant or waste material.
- At least one identifier and/or one security feature is applied to the raw card before the lamination of the at least one film.
- personalization in particular colored personalization, can be made possible by printing.
- the ultrasonic punching is advantageously carried out when the processing tool is excited at a frequency of 10 to 30 kHz, in particular in a range between 18 and 23 kHz.
- a preferred embodiment of the method provides that an interior space formed by the sealing surface of the processing tool is vented during the cutting processing of the film laminated onto the raw card and the interior space is then subjected to compressed air and the data card is ejected.
- the object on which the invention is based is also achieved by a tool for ultrasonic punching of a data card, in which a processing tool attaches to a revolving
- the cutting edge has a sealing surface which is adjacent and aligned with the central axis of the processing tool and the cutting edge of the processing tool can be moved against an anvil, the sealing surface being aligned parallel to the longitudinal axis of the processing tool.
- an exact cut can be made in the at least one film.
- the cut end face of the at least one foil can thereby be aligned with the end face of the raw card.
- the sealing surface adjoining the cutting edge within the processing tool preferably extends in height at least partially along the edge region of the laminate composite to be processed.
- the laminate composite is cut to a final format of the data card by means of a processing step for ultrasonic punching.
- the edge area of the laminate composite is sealed. This can increase security against forgery, since it is more difficult for individual layers of the laminate composite to split open and peel off.
- At least one peripheral shoulder is preferably provided opposite the cutting edge of the machining tool and delimiting the sealing surface.
- an upper edge of the laminate composite can be acted on with this circumferential shoulder during the ultrasonic stamping, with an increased compressive force and thus a secure seal being achieved in this area.
- a contour corresponding to the contour of the shoulder can be transferred to the edge of the data card.
- the shoulder preferably has a rounded shape, so that in particular a burr-free edge that runs around the data card can be achieved.
- the anvil preferably has a bearing surface which is surrounded by a spring-loaded counter-anvil. This makes it possible for the cutting edge to be guided along the edge area of the raw card during the ultrasonic stamping and to be guided past a lower edge of the raw card resting on the support surface.
- the counter anvil is flexible or can be compared to the Bearing surface are moved in an infeed movement of the machining tool. As a result, the cutting edge of the processing tool can be arranged in a recessed manner in relation to the bearing surface of the anvil in order to carry out a complete sealing of the edge region of the data card.
- the machining tool has a bore which opens into an interior space delimited by the sealing surface, via which the interior space can be vented or pressurized with compressed air. This allows for easy ejection of the cut data card after the cutting and sealing process.
- a valve controlling the bore is provided on an outside of the machining tool.
- the interior space can be easily vented during the punching and sealing process and, on the other hand, the process of ejecting the data card can be controlled in a targeted manner.
