Description

Die Erfindung betrifft eine Vorrichtung zum Einbringen mindestens eines in Umfangsrichtung eines Kunststoffverschlusses verlaufenden Schnitts, mit mindestens einem Messer, gemäß Oberbegriff des Anspruchs 1, definiert nach der schrift EP-A-0 657 256.The invention relates to an insertion device at least one in the circumferential direction Plastic closure running cut, with at least one knife, according to the preamble of the claim 1, defined according to EP-A-0 657 256.

Ein in Umfangsrichtung eines Kunststoffverschlusses eingebrachter Schnitt dient beispielsweise der Ausbildung eines Garantierings, der beim Öffnen eines Behälters, auf den der Kunststoffverschluß aufgesetzt ist, zumindest abschnittsweise vom Kunststoffverschluß getrennt wird und/oder derart irreversibel verformt wird, daß ein erstmaliges Öffnen des Behälters angezeigt ist. Vorrichtungen der hier angesprochenen Art sind bekannt. Sie weisen mehrere ortsfest angeordnete Messer auf, an denen ein entlang einer Bewegungsbahn verlagerbarer Kunststoffverschluß vorbeigeführt wird. Im allgemeinen werden hierzu drei -in Verlagerungsrichtung des Verschlusses gesehen- hintereinander angeordnete Messer eingesetzt, an die der Verschluß angedrückt wird und dabei durch seine Verlagerungsbewegung entlang der Bewegungsbahn an diesen abrollt. Hierbei werden von jedem Messer jeweils ein über 120° der Umfangsfläche des Verschlusses verlaufender Teilschnitt in die Umfangsfläche eingebracht, die aneinander angrenzen, wodurch ein durchgehender Schnitt gebildet wird. Mit der bekannten Schneidvorrichtung wird zwar ein durchgehender Schnitt in den Umfang des Verschlusses eingebracht, jedoch weist der Schnitt aufgrund der Messeranordnung und Schneidengeometrie eine -in Umfangsrichtung gesehen- unterschiedliche Tiefe auf. Der Schnittverlauf ist derart, daß im Anfangsbereich eines Messers die Schnittiefe sehr gering ist, zur Mitte des Messers hin größer und ab der Mitte bis zum Endbereich des Messers wieder kleiner wird. Durch diesen Schnittiefenverlauf kann nicht in allen Fällen gewährleistet werden, daß die beim Öffnen des Behälters auf den Garantiering wirkenden Kräfte ausreichen, um diesen in gewünschter Weise zu beschädigen beziehungsweise zu deformieren, so daß ein erstmaliges Öffnen nicht mit Sicherheit erkannt werden kann. Ein weiterer Nachteil des unterschiedlich tiefen Schnitts besteht darin, daß der Garantiering in den Bereichen mit der größten Schnittiefe bereits bei seiner Herstellung beziehungsweise beim Aufsetzen auf den Behälter abschnittsweise vom Verschluß abgetrennt werden kann, was wiederum die Verläßlichkeit des Garantierings verschlechtert.A circumferential direction of a plastic closure introduced cut serves for example for training of a guarantee ring, which when opening a Container on which the plastic closure is placed is, at least in sections of the plastic closure is separated and / or irreversible is deformed that a first opening of the container is displayed. Devices of here addressed type are known. You assign several fixedly arranged knives, along which a a movable plastic closure is led past. Generally will three - in the direction of displacement of the closure seen - knives arranged one behind the other, to which the closure is pressed and doing so by moving it along the Movement path rolls on these. Here are from each knife one over 120 ° of the circumferential surface partial section of the closure in introduced the peripheral surface that adjoin each other, creating a continuous cut becomes. With the known cutting device although a continuous cut in the scope of Introduced closure, but the cut shows due to the knife arrangement and cutting edge geometry a - seen in the circumferential direction - different Depth up. The course of the cut is such that in Initial area of a knife the depth of cut very is small, larger towards the center of the knife and down the middle to the end of the knife again gets smaller. Through this depth of cut course cannot be guaranteed in all cases that the acting on the guarantee ring when opening the container Sufficient forces to get this in the desired Way to damage or deform so opening for the first time is not certain can be recognized. Another disadvantage of the different depth cut is that the guarantee ring in the areas with the greatest depth of cut already during its manufacture or in sections when placed on the container can be separated from the closure, which in turn makes the guarantee ring reliable deteriorated.

Es ist daher Aufgabe der Erfindung, eine Vorrichtung zu schaffen, mittels derer ein in Umfangsrichtung eines Verschlusses verlaufender Schnitt mit konstanter, zumindest aber im wesentlichen konstanter Tiefe eingebracht werden kann.It is therefore an object of the invention to provide a device to create, by means of which a circumferential direction a cut with a closure more constant, or at least essentially more constant Depth can be introduced.

Zur Lösung dieser Aufgabe wird eine Schneidvorrichtung mit den Merkmalen des Anspruchs 1 vorgeschlagen. Bei einem umlaufenden Schnitt wird der Verschluß um 360° gedreht. Zur Einbringung des in Umfangsrichtung des Verschlusses verlaufenden Schnitts wird der Verschluß zunächst mit dem von einer Haltevorrichtung fixierten Messer zusammengeführt und nach dem Kontaktieren des Messers definiert um seine Mittelachse gedreht. Dabei wird mindestens ein in Umfangsrichtung des Verschlusses verlaufender Schnitt mit konstanter Tiefe eingebracht. Die über den Umfang des Verschlusses gleichmäßige Schnittiefe wird dadurch erreicht, daß der Abstand zwischen Verschluß und Messer während der Drehung des Verschlusses um seine Mittelachse nicht verändert wird. Das heißt, zumindest der Bereich des Messers mit dem kleinsten Abstand zur Mittelachse des Verschlusses weist während des Schnittvorgangs gegenüber dem Verschluß eine fixe Position auf. Da für das Einbringen des in Umfangsrichtung des Verschlusses verlaufenden Schnitts lediglich ein einzelnes Messer benötigt wird, können der Aufbau der Schneidvorrichtung vereinfacht und somit deren Kosten reduziert werden.To solve this problem, a cutting device proposed with the features of claim 1. With a circulating Cut the closure is rotated 360 °. to Introduction of the circumferential direction of the closure running cut the closure is first with the knife fixed by a holding device merged and after contacting the knife defined rotated around its central axis. there becomes at least one in the circumferential direction of the closure running cut with constant depth brought in. The over the scope of the closure uniform depth of cut is achieved in that the distance between the lock and knife during the rotation of the closure around its central axis is not changed. That is, at least the area of the knife with the smallest distance to Central axis of the closure points during the Cutting process compared to the closure a fixed Position on. As for the introduction of the circumferential direction of the clipping cut a single knife is needed the structure of the cutting device is simplified and thus reducing their costs.

Besonders bevorzugt wird ein Ausführungsbeispiel der Schneidvorrichtung, das sich dadurch auszeichnet, daß die Bewegungsbahn des Verschlusses eine Kreisbahn ist und daß die das Messer haltende Haltevorrichtung entlang einer geschlossenen, kurvenförmigen Konturbahn verlagerbar ist, deren Mittelpunkt auf den Mittelpunkt der Kreisbahn liegt. Die Schneidvorrichtung weist einen karussellähnlichen Aufbau auf, das heißt, Verschluß und Messer beziehungsweise die das Messer haltende Haltevorrichtung werden während des Schnittvorgangs gemeinsam entlang der ihnen jeweils zugeordneten Bahn, vorzugsweise mit gleicher Umlaufgeschwindigkeit, verlagert.An embodiment is particularly preferred the cutting device, which is characterized by that the trajectory of the closure is one Orbital path and that the holding device holding the knife along a closed, curvilinear Contour path is shiftable, the center of which lies on the center of the circular path. The Cutting device has a carousel-like Structure on, that is, lock and knife respectively the holding device holding the knife are along together during the cutting process the path assigned to them, preferably with the same rotational speed.

Bei einem bevorzugten Ausführungsbeispiel der Schneidvorrichtung ist die Steuerung als Kurvensteuerung ausgebildet, die hier eine Scheibenkurve aufweist. Diese wird von einem mit der Haltevorrichtung für das Messer zusammenwirkenden Tastelement abgetastet. Das Tastelement ist vorzugsweise mit der Haltevorrichtung verbunden, an der das Messer befestigt ist. Durch die Scheibenkurve wird also die Konturbahn, entlang derer die Haltevorrichtung verlagert wird, festgelegt.In a preferred embodiment of the The cutting device is the control as a curve control trained here a disc curve having. This is done by one with the holding device for the knife interacting probe element sampled. The probe element is preferred connected to the holding device on which the knife is attached. Through the disc curve thus the contour path along which the holding device is shifted.

Bei einer vorteilhaften Weiterbildung der Erfindung ist die Schnittiefe einstellbar. Dadurch ist die Möglichkeit gegeben, die Schneidvorrichtung an Kunststoffverschlüsse mit unterschiedlichen Wandstärken, Formen und/oder aus unterschiedlichen Kunststoffen anzupassen beziehungsweise einzustellen.In an advantageous development of the invention the depth of cut is adjustable. This is the Possibility given to the cutting device Plastic closures with different wall thicknesses, Forms and / or from different Adapt or adjust plastics.

Bevorzugt wird auch ein Ausführungsbeispiel der Schneidvorrichtung, bei dem die Position des Messers gegenüber dem Verschluß einstellbar ist. Dadurch kann ein definierter Schnittwinkel eingestellt werden, so daß die Schnittfläche gegenüber einer gedachten Waagerechten um einen Winkel geneigt ist, der größer 0° und kleiner 90° ist. Bei einem anderen Ausführungsbeispiel ist vorgesehen, daß die beim Schneidvorgang gebildete Schnittfläche parallel zur gedachten Waagerechten ist, also senkrecht zur Umfangsfläche des Verschlusses verläuft. An embodiment of the is also preferred Cutting device in which the position of the knife is adjustable relative to the closure. Thereby a defined cutting angle can be set be so that the cut surface is opposite an imaginary horizontal inclined at an angle which is greater than 0 ° and less than 90 °. at another embodiment is provided that the cut surface formed during the cutting process is parallel to the imaginary horizontal, i.e. vertical runs to the peripheral surface of the closure.

Weitere vorteilhafte Ausführungsformen ergeben sich aus den übrigen Unteransprüchen.Further advantageous embodiments result from the other subclaims.

At the guide part 21 facing away The end of the holding device 11 is a feeler element 27 provided that with a controller 29 of the cutting device 1 interacts, and what follows is discussed in more detail.

Die Steuerung 29 ist bei diesem Ausführungsbeispiel als Kurvensteuerung ausgelegt, die eine auch als Kurvenscheibe bezeichnete Konturscheibe 31 umfaßt, die im wesentlichen kreisförmig ausgebildet ist und deren Mittelpunkt auf dem Mittelpunkt 9 der Bewegungsbahn 7 des Verschlusses 3 liegt. Die Konturscheibe 31 weist eine fixe Position auf und dreht sich bei einer Verlagerung der Haltevorrichtung 11 und des Verschlusses 3 nicht mit, sondern bleibt in der in Figur 1 dargestellten Position. Die Konturscheibe 31 weist eine kurvenförmige Außenkontur 33 auf, die von dem Tastelement 27 der in Richtung der Längsmittelachse 20 verschieblich gelagerten Haltevorrichtung 11 abgetastet wird. Dadurch wird die Haltevorrichtung 11 bei einer Drehung um den Mittelpunkt 9 zwangsgeführt und entlang einer Konturbahn verlagert, deren Verlauf der Außenkontur 33 der Konturscheibe 31 entspricht.The controller 29 is in this embodiment designed as a curve control, the one also Includes contoured contour disk 31, which is essentially circular and whose center is on the center 9 of the trajectory 7 of the closure 3 lies. The contour disk 31 has a fixed position and rotates itself when the holding device 11 is displaced and the closure 3 not with, but remains in the position shown in Figure 1. The contour disk 31 has a curved outer contour 33 on by the probe element 27 in the direction of Longitudinal central axis 20 slidably mounted holding device 11 is scanned. This will make the Holding device 11 when rotating around the center 9 positively guided and along a contour path shifted, the course of the outer contour 33 corresponds to the contour disk 31.

Die Konturscheibe 31 weist einen sich über einen Umfangsbereich von circa 110° erstreckenden Teilabschnitt 35.1 auf, der als Kreisbahnabschnitt ausgebildet ist. An den Teilabschnitt 35.1 schließt sich -in Verlagerungsrichtung der Haltevorrichtung 11 und des Verschlusses 3 gesehen (Pfeil 37)- ein sich über einen Umfangsbereich von circa 140° erstrekkender Teilabschnitt 35.2 an, der ebenfalls als Kreisabschnitt ausgebildet ist, wobei dessen Radius kleiner ist als der Radius des Teilabschnitts 35.1. An den Teilabschnitt 35.2 schließt sich ein dritter Teilabschnitt 35.3 an, der sich über einen Umfangsbereich von circa 35° erstreckt. Der Radius der Konturscheibe 31 im Bereich des Teilabschnitts 35.3 ist größer als der Radius sowohl im Bereich des Teilabschnitts 35.2 als auch im Bereich des Teilabschnitts 35.1. Der Übergangsbereich vom Teilabschnitt 35.3 zum Teilabschnitt 35.1 weist einen -in Richtung auf den Mittelpunkt 9 gesehen- nach innen gekrümmten, also konkaven Verlauf auf. Der Übergang von einem Teilabschnitt zum anderen erstreckt sich über einen relativ großen Umfangsbereich der Konturscheibe 31 und zeigt keine scharfen Kanten und Sprünge. Durch die Gestaltung der Übergänge kann die Verlagerungsbeschleunigung, mit der die Haltevorrichtung 11 gegenüber der Bewegungsbahn 11 verlagerbar ist, eingestellt werden.The contour disk 31 has one over one Circumferential area of approximately 110 ° extending section 35.1, which is designed as a circular path section is. The subsection 35.1 follows in the direction of displacement of the holding device 11 and the closure 3 seen (arrow 37) - one over a circumferential range of approximately 140 ° Section 35.2, which also as Circular section is formed, the radius thereof is smaller than the radius of section 35.1. A third section follows on from section 35.2 Section 35.3 on, which extends over a circumferential area extends from approximately 35 °. The radius of the Contour disk 31 in the area of subsection 35.3 is larger than the radius both in the area of Section 35.2 and in the area of the section 35.1. The transition area from the section 35.3 to subsection 35.1 has an -in Direction towards the center 9 seen - inwards curved, i.e. concave course. The transition extends from one section to another over a relatively large circumferential area of the contour disk 31 and shows no sharp edges and Jumps. By designing the transitions the displacement acceleration with which the holding device 11 displaceable relative to the movement path 11 is set.

Bei einer Verlagerung, das heißt Drehung der Haltevorrichtung 11 in Richtung des Pfeils 37 um den Mittelpunkt 9 mittels einer nicht dargestellten Führungseinrichtung wird deren Abstand und somit der Abstand des Messers 15 zur Bewegungsbahn 7 des Verschlusses 3 aufgrund der Zwangsführung durch das Tastelement 27 verändert. In den Umfangsbereichen der Konturscheibe 31 mit konstantem Radius, also in den Teilabschnitten 35.1, 35,2, 35,3, weist die Haltevorrichtung 11 einen konstanten Abstand zur Bewegungsbahn 7 des Verschlusses 3 auf.In the event of a shift, that is to say rotation of the holding device 11 in the direction of arrow 37 Center 9 by means of a not shown Guide device becomes their distance and thus the distance of the knife 15 to the trajectory 7 of the Closure 3 due to the constraint of the Probe 27 changed. In the peripheral areas the contour disk 31 with a constant radius, ie in the sections 35.1, 35.2, 35.3, the Holding device 11 a constant distance from Path of movement 7 of the closure 3.

Im folgenden wird die Funktion der Schneidvorrichtung 1 anhand eines Schneidvorgangs näher erläutert: Der Verschluß 3 wird in der Position A von einer nicht dargestellten Bearbeitungsstation für den Verschluß 3 an die Schneideinrichtung 1 überführt. Wie in Figur 1 dargestellt, wird dabei der Verschluß 3 in die halbkreisförmige Vertiefung 23 des Führungsteils 21 der Haltevorrichtung 11 eingebracht und zentriert. In dieser Position liegt die Seitenfläche 25 des Führungsteils 21 auf der Bewegungsbahn 7. Dann werden Verschluß 3 und Haltevorrichtung 11 gemeinsam in Richtung des Pfeils 37 verlagert, der Verschluß 3 entlang der Bewegungsbahn 7 und die Haltevorrichtung 11 entlang der durch die Außenkontur 33 der Konturscheibe 31 vorgegebenen Konturbahn. Aufgrund des kleineren Radius' der Konturscheibe 31 im Bereich des Teilabschnitts 35.2 gegenüber dem Teilabschnitt 35.1 wird die Haltevorrichtung 11 gegenüber der Bewegungsbahn 7 des Verschlusses in Richtung des Mittelpunkts 9 verlagert. Der Abstand zwischen der Haltevorrichtung 11 und der Bewegungsbahn 7 wird derart vergrößert, daß das Führungsteil 21 den Verschluß 3 freigibt, das heißt, der von der in Figur 1 nicht dargestellten Halterung fixierte Verschluß 3 ist außerhalb des Wirkungsbereichs der Vertiefung 23 geführt. In dem Bereich zwischen der Position B und der Position D weisen Verschluß 3 und Haltevorrichtung 11 einen konstanten Abstand zueinander auf. In dem Überführungsbereich zwischen der Position B und der Position D kann der Verschluß 3 bearbeitet werden, vorzugsweise wird mindestens ein Senkrechteinschnitt in den Bereich des Verschlußumfangs eingebracht, in dem nachfolgend der Garantiering durch einen umlaufenden Schnitt gebildet wird.The following is the function of the cutting device 1 explained in more detail using a cutting process: The closure 3 is in position A from a processing station, not shown, for the closure 3 transferred to the cutting device 1. As shown in Figure 1, the Closure 3 in the semicircular recess 23 of the guide part 21 of the holding device 11 and centered. This is the position Side surface 25 of the guide member 21 on the trajectory 7. Then lock 3 and holding device 11 together in the direction of arrow 37 shifted, the shutter 3 along the path of movement 7 and the holding device 11 along the predetermined by the outer contour 33 of the contour disk 31 Contour path. Due to the smaller radius the contour disk 31 in the region of the section 35.2 compared to subsection 35.1 the holding device 11 opposite the path of movement 7 of the closure in the direction of the center 9 relocated. The distance between the holding device 11 and the movement path 7 is enlarged in such a way that the guide member 21 the closure 3rd releases, that is, that of that in Figure 1 not bracket shown is fixed closure 3 outside the sphere of action of the recess 23 guided. In the area between position B and the position D have closure 3 and holding device 11 a constant distance from each other. In the transfer area between positions B and the position D, the closure 3 can be processed, preferably at least one vertical incision is made introduced into the area of the closure circumference, in which the guarantee ring follows a circumferential cut is formed.

Der in Umfangsrichtung des Verschlusses 3 verlaufende Schnitt wird im Bereich des Teilabschnitts 35.3 eingebracht. In diesem Teilabschnitt ist die Haltevorrichtung 11 nach außen in Richtung der Bewegungsbahn 7 verlagert, so daß der Verschluß 3 in der Vertiefung 23 des Führungsteils 21 geführt wird, wobei der Abstand zwischen Verschluß 3 und dem in die Vertiefung 23 hineinragenden Messer 15 so gering ist, daß der Schnitt in den Umfang des Verschlusses 3 eingebracht werden kann. Hierzu wird der Verschluß 3 im Bereich des Teilabschnitts 35.3 zumindest um 360° um seine Mittelachse 5 gedreht, wodurch ein in Umfangsrichtung des Verschlusses 3 verlaufender Schnitt eingebracht wird. Dadurch, daß im Bereich des Teilabschnitts 35.3 die Konturscheibe 31 einen konstanten Radius aufweist, ist der Abstand zwischen dem Verschluß 3 und dem Messer 15 während der 360°-Drehung konstant, also auch die Tiefe des Schnitts. Anschließend wird der Verschluß 3 in der Position F aus der Schneidvorrichtung 1 geführt. The one running in the circumferential direction of the closure 3 Cut is in the area of the section 35.3 introduced. In this section the Holding device 11 outwards in the direction of the movement path 7 shifted so that the closure 3 in the recess 23 of the guide member 21 out is, the distance between the closure 3 and the knife 15 protruding into the recess 23 is so small that the cut in the circumference of the Closure 3 can be introduced. This will the closure 3 in the area of subsection 35.3 rotated at least 360 ° around its central axis 5, whereby a in the circumferential direction of the closure 3rd running cut is introduced. As a result of that the contour disk in the area of subsection 35.3 31 has a constant radius the distance between the closure 3 and the knife 15 constant during the 360 ° rotation, including that Depth of cut. Then the closure 3 in position F from the cutting device 1 guided.

Figur 2 zeigt ein Ausführungsbeispiel einer Halterung 39 für den Verschluß 3, die ein stiftförmiges Halteelement 41 und ein mit diesem drehfest verbundenes Zahnrad 43 aufweist. Das Zahnrad 43 wirkt mit einer nicht dargestellten Antriebseinrichtung zusammen, mittels derer die Drehgeschwindigkeit des Verschlusses 3 um seine Mittelachse 5 einstellbar ist. Die Drehgeschwindigkeit des Verschlusses 3 ist im Bereich des Teilabschnitts 35.3 zumindest so hoch, daß er eine 360°-Drehung durchführt, wodurch der in Umfangsrichtung verlaufende Schnitt eingebracht wird.Figure 2 shows an embodiment of a holder 39 for the closure 3, which is a pen-shaped Holding element 41 and a non-rotatably connected thereto Gear 43 has. The gear 43 cooperates a drive device, not shown, together, by means of which the rotational speed of the Closure 3 adjustable about its central axis 5 is. The rotational speed of the shutter 3 is in the area of subsection 35.3 at least like this high that he makes a 360 ° turn, which makes introduced the cut running in the circumferential direction becomes.

Bei einem weiteren -nicht dargestellten- Ausführungsbeispiel weist die anhand von Figur 1 beschriebene Schneidvorrichtung 1 mehrere Haltevorrichcungen 11 mit jeweils mindestens einem Messer auf. Dadurch kann deren Durchsatz, das heißt, die Anzahl der von der Schneideinrichtung bearbeiteten Verschlüsse erhöht werden. Vorteilhaft ist ferner, daß durch die Verwendung von mehreren Messern deren Standzeit erhöht wird und somit die Wartungsintervalle der Schneidvorrichtung, bei denen die einem Verschleiß unterliegenden Messer ausgetauscht werden. Jeweils ein Verschluß und eine ein Messer aufweisende Haltevorrichtung werden gemeinsam vom Einlauf (Position A) der Schneidvorrichtung bis zu deren Auslauf (Position F) geführt, das heißt, sie weisen gleiche Umlaufgeschwindigkeiten auf.In a further embodiment (not shown) has that described with reference to Figure 1 Cutting device 1 several holding devices 11 with at least one knife each on. This allows their throughput, that is, the Number of processed by the cutter Closures are increased. It is also advantageous that by using multiple knives Service life is increased and thus the maintenance intervals the cutting device in which the one Knives subject to wear can be replaced. One closure each and one with a knife Holding device are together from the inlet (Position A) of the cutting device up to its Outlet (position F) led, that is, they have the same circulation speeds.

Das am Einstellelement 13 befestigte Messer 15 ist vorzugsweise als auswechselbare Schneidplatte ausgebildet, so daß bei einem Verschleiß des Messers dieses einfach und schnell ausgetauscht werden kann. Das Messer 15 weist bei dem in Figur 1 dargestellten Ausführungsbeispiel eine gerade Schneide auf, die rein beispielhaft tangential zum Umfang des Verschlusses ausgerichtet ist. Um in den Umfang einen Schnitt mit konstanter Tiefe einzubringen, kann das Messer gegenüber dem Verschluß auch in einem spitzen oder stumpfen Winkel geneigt sein.The knife 15 attached to the adjusting element 13 is preferably designed as an interchangeable insert, so that if the knife wears out this can be exchanged easily and quickly can. The knife 15 points at the one shown in FIG Embodiment a straight edge on that is purely exemplary tangential to the scope the closure is aligned. To the extent make a cut with constant depth, can the knife compared to the closure in one be acute or obtuse.

Zusammenfassend ist festzuhalten, daß mit der Schneideinrichtung 1 ein exakter, in Umfangsrichtung eines Verschlusses verlaufender Schnitt in diesen eingebracht werden kann, wodurch vorzugsweise ein auch als Garantieband bezeichneter Garantiering gebildet wird. Die Schnittiefe wird durch die Konturscheibe 31 festgelegt, die die Relativbewegung der Haltevorrichtung 11 gegenüber der Bewegungsbahn 7 des Verschlusses 3 steuert. Mit Hilfe des Einstellelements 13, an dem das Messer 15 befestigt ist, kann eine Feineinstellung der Schnittiefe vorgenommen werden, um beispielsweise Toleranzen der einzelnen Vorrichtungsteile auszugleichen. Während des Schneidvorgangs ist der Abstand zwischen Messer und Verschluß konstant, so daß der Schnitt über den gesamten Umfang des Verschlusses eine konstante Tiefe aufweist, wodurch die Originalitäts-Anzeigefunktion des Garantierings mit hoher Sicherheit gewährleistet werden kann. Es zeigt sich im übrigen auch, daß in die Verschlüsse auch in Umfangsrichtung verlaufende Schnitte eingebracht werden, die nicht vollständig umlaufend, das heißt in sich geschlossen, sind. Um dies zu realisieren ist es lediglich erforderlich, die Drehbewegung des Verschlusses, der sich im Teilbereich 35.3 befindet zu begrenzen, beispielsweise auf 120°, 240° oder dergleichen.In summary, it should be noted that with the Cutting device 1 an exact, in the circumferential direction of a closure running cut in this can be introduced, whereby preferably a guarantee ring, also known as a guarantee band is formed. The depth of cut is determined by the contour disc 31 determines the relative movement the holding device 11 opposite the path of movement 7 of the closure 3 controls. With help of the setting element 13 to which the knife 15 is attached is a fine adjustment of the depth of cut be made, for example, tolerances to compensate for the individual parts of the device. The distance is during the cutting process constant between knife and lock, so that the Cut across the entire circumference of the clasp has a constant depth, resulting in the originality display function of the guarantee ring with high Security can be guaranteed. It appears otherwise also that in the closures also in the circumferential direction running cuts are made, which is not completely circulating, that is, in are closed. To realize this it only required the rotational movement of the Closure, which is located in section 35.3 limit, for example to 120 °, 240 ° or like.
