Abstract

The code marking (4) at a yarn (2) is formed by its surface, containing a barcode (6) and the like. The code markings are repeated at set intervals of 5-100 mm along the yarn. The code marking can be on a film wrapping around the yarn, which is water-soluble or removed by a solvent.

Description

Die Erfindung betrifft einen Faden mit einer Codierung, ein Verfahren zur Herstellung eines codierten Fadens, sowie Verwendungen eines codierten Fadens.The invention relates to a thread with a coding, a method for Production of a coded thread, and uses of a coded Thread.

Bei bekannten codierten Fäden kann, wenn z. B. ein Kleidungsstück, in dem der Faden verarbeitet ist, stark beansprucht bzw. beschädigt ist, nicht auf den Ursprungszustand des Fadens vor oder kurz nach dem Nähvorgang geschlossen werden. Daher kann der Faden, d.h. ein Garn oder ein Zwirn, meist nicht einer einzelnen Charge zugeordnet werden. Dadurch wird es schwierig, die Ursache einer Reklamation zu bestimmen. Ferner können bei der Verarbeitung eines bekannten codierten Fadens keine Aussagen über den Fadenverbrauch, d.h. über die Verarbeitungsqualität getroffen werden. Zudem muß zur Bestimmung von auf den Faden wirkenden Kräften eine physikalische Prüfung unter Zerstörung des Fadens durchgeführt werden, beispielsweise durch Prüfung auf Reißfestigkeit und Bruchdehnung.In known coded threads, if, for. B. a garment in the thread is processed, heavily used or damaged, not to the original state of the thread before or shortly after Sewing process can be closed. Therefore, the thread, i.e. a yarn or a twine, usually not assigned to a single batch. This makes it difficult to determine the cause of a complaint. Furthermore, when processing a known coded thread no statements about thread consumption, i.e. about the build quality to be hit. In addition, to determine the A physical test under destruction of the thread can be carried out, for example by testing for tensile strength and elongation at break.

Aus der WO98/38365 ist ein Garn bekannt, das mindestens eine lesbare, durch einen geeigneten Lesesensor identifizierbare Faser enthält, die im Inneren des Garns versteckt ist. Diese Faser wird zur Sicherung der Authentizität des Garns und des Produktes, z.B. eines Kleidungsstücks, in dem das Garn verarbeitet wurde, verwendet. So können mit Hilfe der Faser Rückschlüsse auf den Hersteller des Garns bzw. des Kleidungsstücks gezogen werden. From WO98 / 38365 a yarn is known which has at least one readable, contains a fiber that can be identified by a suitable reading sensor Is hidden inside the yarn. This fiber is used to ensure authenticity the yarn and the product, e.g. a garment, in the yarn was processed. So with the help of Fiber conclusions about the manufacturer of the yarn or garment to be pulled.

Aufgabe der Erfindung ist es, einen Faden mit einer Codierung anzugeben, die eine möglichst einfache Identifizierung, Verarbeitung und Prüfung des Fadens ermöglicht, wobei der codierte Faden möglichst einfach herstellbar sein soll.The object of the invention is to specify a thread with a coding, which makes it as easy as possible to identify, process and check the Thread allows, the coded thread as easy to manufacture should be.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale der unabhängigen Ansprüche.This task is solved by the characteristics of the independent Expectations.

Vorteilhafte Ausführungsformen der Erfindung sind in der Beschreibung, der Zeichnung und den Unteransprüchen beschrieben.Advantageous embodiments of the invention are in the description, the drawing and the subclaims.

Die Aufgabe wird insbesondere dadurch gelöst, dass die Oberfläche des Fadens als die Codierung ausgebildet ist. Dadurch, daß die Oberfläche des Fadens die Codierung bildet, genügt ein einfaches Verfahren zum Lesen der Codierung. Außerdem wird dadurch ermöglicht, dass nach der Herstellung des Fadens die Codierung auf einfache Weise nachträglich aufgebracht werden kann.The object is achieved in particular in that the surface of the Thread is formed as the coding. The fact that the surface of the Fadens forms the coding, a simple method for reading is sufficient the coding. It also enables that after manufacture of the thread, the coding subsequently applied in a simple manner can be.

Die Codierung kann eine Längeninformation umfassen. Dies bewirkt, dass die Codierung nicht nur als Information über den Faden bzw. über das Produkt, in dem der Faden verarbeitet ist, den zugehörigen Hersteller und die zugehörige Charge, sondern auch zur Feststellung von Änderungen der Länge des Fadens dienen kann, die während oder nach seiner Verarbeitung z. B. durch einen Unfall verursacht werden. Zudem kann mittels der Längeninformation der Fadenverbrauch während der Verarbeitung des Fadens bestimmt und gesteuert werden und somit die Stichbildung mit Auswirkungen z.B. auf Nahtfestigkeit oder Dehnung.The coding can include length information. This causes that the coding not only as information about the thread or about the Product in which the thread is processed, the associated manufacturer and the associated batch, but also to detect changes the length of the thread can serve during or after its processing z. B. caused by an accident. In addition, by means of the length information of the thread consumption during the processing of the Thread can be determined and controlled and thus the stitch formation with Effects e.g. for seam strength or stretch.

Die Codierung kann eine Markierung aufweisen, die sich in vorbestimmten Abständen, bevorzugt in Abständen von etwa 5 - 100 mm, entlang des Fadens wiederholt. Die Abstände können dabei so gewählt sein, dass sie sowohl für den Hersteller des Fadens, für den Faden und seine Charge, als auch für die Länge einzelner Abschnitte des Fadens charakteristisch sind. Alternativ kann die Codierung so ausgestaltet sein, dass jede Markierung Informationen über den Hersteller, den Faden und seine Charge, beispielsweise in Form eines Streifencodes, eines magnetischen Codes oder eines zweidimensionalen Punktcodes enthält und die Abstände eine Längeninformation bilden, mit der der Fadenverbrauch und die auf den Faden wirkenden Kräfte bestimmt werden können. Durch die Abstände kann erreicht werden, dass Abschnitte des Fadens, die weniger stark beschädigt sind und eine Markierung enthalten, zur Identifizierung des Fadens und seiner Charge dienen können. Zudem kann durch Bestimmen der Abstände während der Verarbeitung festgestellt werden, ob sich der Fadenverbrauch ändert. Auch die auf die Faden wirkenden Kräfte können durch Bestimmen der Abstände z.B. vor und nach einer Beanspruchung mit entsprechender Längenänderung ohne Zerstörung des Fadens ermittelt werden.The coding can have a marking which is in predetermined Distances, preferably at intervals of about 5-100 mm, along the Fadens repeated. The distances can be chosen so that they both for the manufacturer of the thread, for the thread and its batch, as well as characteristic of the length of individual sections of the thread are. Alternatively, the coding can be designed such that each marking Information about the manufacturer, the thread and its batch, for example in the form of a bar code, a magnetic code or a two-dimensional point code and the distances one Form length information with which the thread consumption and on the Thread-acting forces can be determined. Through the gaps can be achieved that sections of the thread that are less strong are damaged and contain a marking to identify the Fadens and its batch can serve. In addition, by determining the distances during processing are determined whether the Thread consumption changes. The forces acting on the thread can also by determining the distances e.g. before and after a stress determined with a corresponding change in length without destroying the thread become.

In einer bevorzugten Ausgestaltung kann die Oberfläche des Fadens eine Ummantelung aufweisen, die als die Codierung ausgebildet ist. Dabei wird die Oberfläche des Fadens von der Ummantelung gebildet. So kann die Codierung in oder auf der Ummantelung des Fadens vorgesehen sein. Dadurch wird vermieden, dass der Faden selbst verändert wird.In a preferred embodiment, the surface of the thread can be a Have casing, which is designed as the coding. Doing so the surface of the thread is formed by the sheath. So it can Coding can be provided in or on the sheath of the thread. This prevents the thread itself from being changed.

Die Ummantelung kann in Form eines auf dem Faden aufgebrachten Films vorgesehen sein.The sheath can be applied in the form of a thread Film will be provided.

Die Ummantelung kann ferner zumindest teilweise, insbesondere mit einem Lösungsmittel, entfernbar sein. Durch Entfernen der Ummantelung kann nach dem Lesen der Codierung, beispielsweise nach der Verarbeitung des Fadens, der Zustand des unbedeckten Fadens wiederhergestellt werden.The casing can also at least partially, in particular with a solvent. By removing the jacket can after reading the coding, for example after processing of the thread, the state of the uncovered thread is restored become.

Alternativ kann auch nur die Codierung, insbesondere mit einem Lösungsmittel, entfernbar sein. So wird nach dem Entfernen der Codierung der uncodierte Zustand des Fadens wiederhergestellt, bzw. bei einem Faden mit Ummantelung, auf der die Codierung aufgebracht ist, verbleibt nach dem Entfernen der Codierung der ummantelte Faden.Alternatively, only the coding, in particular with a solvent, be removable. So after removing the coding the uncoded state of the thread is restored, or at one Thread with sheathing on which the coding is applied remains after removing the coding of the covered thread.

Die Codierung kann durch Verformung der Oberfläche des Fadens, insbesondere durch plastische Verformung, gebildet sein. Beispielsweise kann der Faden oder - bei einem Faden mit Ummantelung - seine Ummantelung plastisch verformbar und die Codierung dadurch erhältlich sein, dass der Faden z. B. mit erhitzten Prägestempeln derart bearbeitet wird, daß die äußere Oberfläche eine Struktur erhält, die die gewünschte Information beinhaltet.The coding can be done by deforming the surface of the thread, in particular be formed by plastic deformation. For example the thread or - in the case of a thread with a covering - its covering plastically deformable and the coding thereby be available, that the thread z. B. is processed with heated dies such that the outer surface gets a structure that the desired information includes.

Die Codierung kann von einem optisch lesbaren Codiermaterial auf der Oberfläche des Fadens gebildet sein. Das Codiermaterial kann z. B. aus einem aufgedruckten Farbstoff bestehen, der nur unter UV-Bestrahlung sichtbar ist. So wird das bei normaler Beleuchtung erkennbare Erscheinungsbild des Fadens durch die Codierung nicht verändert.The coding can be from an optically readable coding material on the Surface of the thread can be formed. The coding material can e.g. B. from a printed dye that exist only under UV radiation is visible. This is the appearance that can be seen under normal lighting of the thread is not changed by the coding.

Die Lösung der Aufgabe erfolgt außerdem durch die Merkmale des unabhängigen Verfahrensanspruchs und insbesondere dadurch, dass die Oberfläche des Fadens als eine Codierung ausgebildet wird. Wie oben erläutert kann dadurch erreicht werden, dass ein einfaches Verfahren zum Lesen der Codierung genügt. Außerdem wird durch Ausbildung der Oberfläche des Fadens als die Codierung ermöglicht, dass nach der Herstellung des Fadens die Codierung auf einfache Weise nachträglich aufgebracht werden kann.The task is also solved by the characteristics of the independent Process claim and in particular in that the Surface of the thread is formed as a coding. As above can be achieved by using a simple method to read the coding. In addition, by training the Surface of the thread as the coding allows that after manufacture of the thread, the coding subsequently applied in a simple manner can be.

Mittels der Codierung kann eine Längeninformation codiert werden. Dies ermöglicht eine einfache Bestimmung der Fadenlänge bzw. des Fadenvorrats während der Verarbeitung des Fadens.Length information can be encoded using the coding. This enables easy determination of the thread length or the thread supply during the processing of the thread.

Der Faden kann zur Bildung der Codierung mit einer Markierung, die sich in vorbestimmten Abständen, bevorzugt in Abständen von etwa 5 - 100 mm, entlang des Fadens wiederholt, versehen werden.The thread can be used to form the coding with a marking that extends at predetermined intervals, preferably at intervals of approximately 5-100 mm, repeated along the thread.

Zur Bildung der Codierung kann die Oberfläche des Fadens verformt, insbesondere plastisch verformt werden. Dies kann z. B. dadurch geschehen, dass die Oberfläche des Fadens, die aus plastisch verformbaren Material besteht, bzw. eine Ummantelung aus plastisch verformbaren Material mittels Prägestempeln derart strukturiert wird, dass die gewünschte Information enthalten ist.The surface of the thread can be deformed to form the coding, especially plastically deformed. This can e.g. B. done by that the surface of the thread that is made of plastically deformable Material consists, or a casing made of plastically deformable Material is structured by means of embossing stamps in such a way that the desired one Information is included.

Ferner kann beim Ausbilden der Codierung ein auf der Oberfläche des Fadens haftendes Codiermaterial aufgebracht werden.Furthermore, when the coding is formed, a on the surface of the Thread coding adhesive material are applied.

Dabei kann ein optisch lesbares Codiermaterial verwendet werden.An optically readable coding material can be used.

Die Oberfläche des Fadens kann mit einer die Codierung bildenden Ummantelung versehen werden. Die Codierung kann dabei in oder auf der Ummantelung des Fadens vorgesehen werden.The surface of the thread can be encased with a coating be provided. The coding can be in or on the Sheathing of the thread can be provided.

Dabei kann eine, insbesondere mit einem Lösungsmittel, zumindest teilweise entfernbare und bevorzugt wasserlösliche Ummantelung verwendet werden. Daher kann der Faden z. B. nach seiner Verarbeitung durch Entfernen der Ummantelung wieder in seinen ursprünglichen Zustand bzw. in sein ursprüngliches Erscheinungsbild überführt werden.One can, at least partially, in particular with a solvent removable and preferably water-soluble casing used become. Therefore, the thread z. B. after its processing Remove the jacket back to its original condition or be converted into its original appearance.

Erfindungsgemäß kann ein codierter Faden zur Identifizierung des Fadens oder eines den Faden umfassenden Produktes verwendet werden. Wenn die Oberfläche des Fadens in einer Mehrzahl von Bereichen als Codierung ausgebildet ist, wird im Falle einer Beschädigung des Fadens bzw. eines zugehörigen Kleidungsstückes, die Identifizierung des Fadens erleichtert, da unbeschädigte Bereiche zur Identifizierung dienen können. So hat jeder Faden seine eigene Identität und das aufwendige Registrieren von Chargen für das Nachvollziehen bei Reklamationen entfällt. Die Identität des Fadens kann ferner bei der Verfolgung von Produktpiraterie eingesetzt werden. Zudem ist die als Codierung ausgebildete Oberfläche von außen leicht zugänglich, was dazu führt, dass die Codierung einfach, d. h. mit einem einfachen Leseverfahren lesbar ist. Ferner kann die Codierung nach der Herstellung des Fadens, d.h. nachträglich vorgesehen werden.According to the invention, a coded thread for identifying the thread or a product comprising the thread can be used. If the surface of the thread in a plurality of areas as coding is formed in the event of damage to the thread or associated garment, which makes it easier to identify the thread, undamaged areas can be used for identification. So everyone has Thread his own identity and the complex registration of batches there is no need for tracing complaints. The identity of the thread can also be used to track product piracy. In addition, the surface designed as coding is from the outside easily accessible, making coding easy, i. H. With is easy to read. Furthermore, the coding can be the manufacture of the thread, i.e. can be provided later.

Außerdem kann erfindungsgemäß ein codierter Faden zur Bestimmung und/oder Steuerung des Fadenverbrauchs bei der Fadenverarbeitung und insbesondere bei der Herstellung von Nähten verwendet werden. Eine Codierung mit einer Längeninformation ermöglicht genaue Aussagen über den Fadenverbrauch bezogen auf eine vorgegebene Nahtlänge, aber auch z. B. bei Nähstichtypen mit mehr als einem Faden Aussagen über das Fadenverhältnis von z. B. Nadel- zu Greiferfaden. Daraus ist dann mittels entsprechender Lesegeräte beim Nähvorgang zu erkennen, ob die Stichbildung optimal ist im Hinblick auf die Nahtfestigkeit und die Nahtdehnung. So kann über eine Steuerung des Fadenverbrauchs der Fadenvorrat in der Naht und damit das Nahtverhalten kontrolliert werden.In addition, according to the invention, a coded thread can be used for the determination and / or control of thread consumption during thread processing and can be used especially in the production of seams. A Coding with length information enables precise statements about the thread consumption related to a given seam length, but also z. B. for stitch types with more than one thread statements about the Thread ratio of z. B. needle to looper thread. From this is then means appropriate readers during the sewing process to recognize whether the stitch formation is optimal in terms of seam strength and seam stretching. For example, the thread supply in the can be controlled by controlling the thread consumption Seam and thus the seam behavior can be checked.

Erfindungsgemäß kann ferner ein codierter Faden zur Bestimmung von auf den Faden oder auf ein den Faden umfassendes Produkt einwirkenden und insbesondere zu Fadendehnungen führenden Kräften verwendet werden. Enthält die Codierung eine Längeninformation, können durch Ermittlung der Länge vor und nach dem Nähen übermäßige Dehnungen des Fadens beim Nähvorgang bestimmt werden. Auch nach einem Verkehrsunfall kann die Länge eines Abschnitts eines z. B. im Sicherheitsgurt verarbeiteten codierten Fadens mit der ursprünglichen Länge verglichen und daraus eine unfallbedingte Dehnung des Fadens und damit des Sicherheitsgurtes bestimmt werden. Dadurch können Krafteinwirkungen ohne physikalische Zerstörung des Fadens ermittelt und Längenveränderungen den Kräften und deren möglichen Ursachen zugeordnet werden. Dies kann vorteilhaft auch in der Kriminalistik eingesetzt werden.According to the invention, a coded thread for determining acting on the thread or on a product comprising the thread and used in particular forces leading to thread stretching become. If the coding contains length information, you can use Determine the length before and after sewing excessive stretching of the thread can be determined during the sewing process. Even after a traffic accident can the length of a portion of a z. B. in the seat belt processed coded thread compared to the original length and from this an accident-related stretching of the thread and thus the Seat belt to be determined. This can cause force determined without physical destruction of the thread and changes in length be assigned to the forces and their possible causes. This can also be used to advantage in forensic science.

In der ersten Ausführungsform gemäß Fig. 1 und 2 weist ein Faden 2 auf seiner Oberfläche in gleichbleibenden Abständen B eine Markierung 4 auf. Die Markierung 4 besteht aus einem nur im UV-Licht sichtbaren Farbstoff, der in Form eines für den Hersteller, den Faden und seine Charge charakteristischen Streifencodes 6 auf den Faden 2 aufgebracht ist. Mit dem Streifencode 6 besitzt daher jeder Faden seine eigene Identität. Die Abstände B dienen als Längeninformation zur Steuerung des Fadenverbrauchs beim Nähvorgang und zur Realisierung eines kontrollierten Nahtverhaltens. Da der Streifencode stark verkleinert punktuell als sogenannte Mikrocodierung vorgesehen und zudem nur im UV-Licht erkennbar ist, wird das äußere Erscheinungsbild des Fadens praktisch nicht beeinflusst.In the first embodiment according to FIGS. 1 and 2, a thread 2 has a mark 4 on its surface at constant intervals B. The marking 4 consists of a dye that is only visible in UV light, the one for the manufacturer, the thread and its batch characteristic bar codes 6 is applied to the thread 2. With the stripe code 6 therefore each thread has its own identity. The Distances B serve as length information for controlling the thread consumption during the sewing process and to implement a controlled Seam behavior. Since the bar code is greatly reduced in places as so-called Microcoding provided and also only recognizable in UV light is, the outer appearance of the thread is practically not affected.

Der Streifencode 6 wird mit einem entsprechenden Druckstempel nach der Herstellung des uncodierten Fadens 2 in den Abständen B auf den unbeanspruchten und ungedehnten Faden aufgedruckt. Herkömmliche Produktionslinien für Fäden können durch Einbau einer entsprechenden Codierstation einfach und kostengünstig umgerüstet werden.The stripe code 6 is followed by a corresponding stamp the production of the uncoded thread 2 at intervals B on the unstressed and unstretched thread printed on. conventional Production lines for threads can be installed by installing an appropriate one Coding station can be converted easily and inexpensively.

Zum Lesen der Codierung gemäß der ersten Ausführungsform wird mit einem Lesegerät der codierte Faden mit UV-Licht bestrahlt, der Streifencode mit einem im Wellenlängenbereich des UV-Farbstoffs aktiven Sensor erfasst und ausgelesen und entlang des Fadens die Abstände B bestimmt.To read the coding according to the first embodiment, use a reader the coded thread is irradiated with UV light, the stripe code with a sensor active in the wavelength range of the UV dye detected and read and the distances B determined along the thread.

In der zweiten Ausführungsform gemäß Fig. 3 und 4 besteht die Oberfläche des Fadens 8 aus einer Ummantelung 10, die den Kern 12 des Fadens 8 einhüllt. Die Ummantelung 10 besteht aus einem in Wasser oder einem anderen Lösungsmittel löslichen Material. Außerdem ist die Ummantelung 10 in Abständen C und D mit Vertiefungen 14 versehen, wobei die verschieden großen Abstände C und D für den Hersteller, den Faden und seine Charge als Code kennzeichnend sind. Die Vertiefungen 14 sind nur in der Ummantelung 10 vorgesehen, so dass der Kern 12 des Fadens 8 unverändert bleibt. Dies ermöglicht, dass nach dem Lesen der im Code enthaltenen Information die Ummantelung 10 in Wasser bzw. dem Lösungsmittel aufgelöst und der uncodierte Kern 12 des Fadens 8 freigelegt werden kann.In the second embodiment according to FIGS. 3 and 4, the surface exists of the thread 8 from a sheath 10, which the core 12 of the thread 8 envelops. The casing 10 consists of one in water or one other solvent soluble material. In addition, the casing 10 at intervals C and D with depressions 14, the different large distances C and D for the manufacturer, the thread and identifying his batch as a code. The depressions 14 are only provided in the sheath 10 so that the core 12 of the thread 8th remains unchanged. This allows that after reading the code contained information the casing 10 in water or the solvent resolved and the uncoded core 12 of the thread 8 exposed can be.

Die Herstellung des Fadens 8 beginnt mit der Erzeugung des Kerns 12, der ein herkömmlicher uncodierter Faden ist. Dieser wird dann durch Eintauchen in eine Lösung des plastifizierbaren Materials der Ummantelung und durch Verdampfen des Lösungsmittels mit der Ummantelung 10 versehen. Weiterhin kann die Ummantelung 10 z.B. durch statische Aufladung des Fadens in Art einer Beflockung oder durch Aufdampfen im Vakuum (Eloxalverfahren) erzeugt werden. Nachdem die Ummantelung 10 getrocknet ist, wird sie z. B. mit erhitzten Prägestempeln strukturiert, indem die Vertiefungen 14 in den Abständen C und D eingeprägt werden.The production of the thread 8 begins with the production of the core 12, which is a conventional uncoded thread. This is then through Immerse in a solution of the plasticizable material of the casing and by evaporating the solvent with the jacket 10 Mistake. Furthermore, the casing 10 can e.g. through static charge of the thread in the manner of a flocking or by vapor deposition in the Vacuum (anodizing process) are generated. After the casing 10 is dried, z. B. structured with heated dies, by embossing the depressions 14 at intervals C and D.

Beim Lesen der Codierung der zweiten Ausführungsform wird ein Lesegerät eingesetzt, das entlang des Fadens die Vertiefungen 14 z. B. mit einem Höhenunterschiede erfassenden Sensor, der beispielsweise einen Laser aufweist, registriert und damit auch die Abstände C und D bestimmt. When reading the coding of the second embodiment, a reader used, the wells 14 along the thread z. B. with a Height-detecting sensor, for example a laser has, registered and thus also determined the distances C and D.
