Description

Die Erfindung betrifft einen Kassettenstapel aus einzelnen Kassetten, vorzugsweise zur Aufnahme von Präparaten für Laboranalysen, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a cassette stack of individual cassettes, preferably for receiving preparations for laboratory analysis, according to the preamble of patent claim 1.

Die Kassetten eines derartigen Stapels, auch Einbettkassetten genannt, dienen beispielsweise in medizinischen Laboren als Aufnahmebehälter für histologische Proben. Die Kassetten werden zu Ihrer Unterscheidung manuell oder maschinell beschriftet. Um bei der maschinellen Beschriftung nicht jede einzelne Kassette händisch separat in den Druckerschacht eines Druckers bzw. ein Kassettenmagazin einführen zu müssen, werden Kassetten zu einem Kassettenstapel miteinander verbunden, der dann in einen Schacht eingesetzt wird. Dabei ist die einfachste Möglichkeit, die aufeinanderliegenden Kassetten mittels einer außen um sie herum geführten Schnur zu verbinden.The cassettes of such a stack, also called Einbettkassetten serve, for example, in medical laboratories as receptacles for histological samples. The cassettes are labeled manually or mechanically for your distinction. In order not to have to manually insert each individual cassette manually into the printer slot of a printer or a cassette magazine when machine labeling, cassettes are connected to a cassette stack with each other, which is then inserted into a slot. The easiest way to connect the stacked cassettes by means of a guided around them outside cord.

In der EP 1 238 706 A2 wird vorgeschlagen, die Kassetten mittels eines längs der Kassetten verlaufenden Klebebandes miteinander zu verbinden, oder über eine dünne Schweißnaht. Hierbei ist jedoch nachteilig, dass nach dem Einführen des Kassettenstapels in den Druckerschacht bzw. in das Kassettenmagazin und vor dem Bedrucken die Kassetten nur durch Aufschneiden, Lösen bzw. durch ein Auftrennen des Klebebandes bzw. der Schweißnaht vereinzelt werden können, um sie dann als Einbettkassette nutzen zu können. Außerdem kann, je nach Gestaltung des Druckerschachts bzw. Kassettenmagazins, das Aufschneiden, Lösen bzw. Auftrennen des Klebebandes bzw. der Schweißnaht durch in diesem Bereich vorhandene Wände oder Wandbereiche des Druckerschachts behindert, zumindest aber erschwert sein. Im Fall der Verbindung der Kassetten über Klebebänder können nach dem Abtrennen des Klebebandes Klebereste außen an den Kassetten haften bleiben, was das Rutschen der Kassetten in dem Druckerschacht bzw. Kassettenmagazin erschweren kann.In the EP 1 238 706 A2 It is proposed to connect the cassettes by means of an adhesive tape running along the cassettes, or via a thin weld. In this case, however, it is disadvantageous that after the insertion of the cassette stack into the printer shaft or into the cassette magazine and before printing, the cassettes can only be singled out by cutting, loosening or by separating the adhesive tape or the weld, in order to then use them as an embedding cassette to be able to use. In addition, depending on the design of the printer shaft or cartridge magazine, the cutting, loosening or separation of the adhesive tape or the weld may be hindered by existing in this area walls or wall areas of the printing shaft, but at least be difficult. In the case of connecting the cassettes via adhesive tapes, adhesive residues may adhere to the cassettes on the outside after separation of the adhesive tape, which may make it difficult to slide the cassettes in the printer tray or cassette magazine.

Als Alternative zu der in der EP 1 238 706 A2 beschriebenen Verbindungstechnik bestünde die Möglichkeit, die Kassetten mittels einer längs des Kassettenstapels gezogenen Klebenaht zu verbinden, etwa einer Klebenaht aus Silikon-, Heiß- oder Flüssigkleber. Aber auch in diesem Fall wäre das Aufschneiden, Lösen bzw. Auftrennen der Klebenaht durch in diesem Bereich vorhandene Wände oder Wandbereiche des Druckerschachts erschwert. Außerdem können nach dem Trennen der Klebenaht Reste an den Kassetten haften bleiben, was das Rutschen der Kassetten in dem Druckerschacht bzw. Kassettenmagazin erschweren kann.As an alternative to that in the EP 1 238 706 A2 described connection technology would be possible to connect the cassette by means of a drawn along the cassette stack adhesive seam, such as a glued seam of silicone, hot or liquid adhesive. But even in this case would be the slicing, loosening or separating the adhesive seam through in this Area existing walls or wall areas of the printer shaft difficult. In addition, residues may adhere to the cassettes after separation of the adhesive seam, which may make it difficult for the cassettes to slip in the printer tray or cassette magazine.

Aus der US 2005/0152809 A1 ist es bekannt, zu einem Stapel angeordnete Kassetten, die jeweils mit einem bedruckbaren Beschriftungsfeld versehen sein können, auf einen gemeinsamen Strang aufzufädeln. Zu diesem Zweck sind die Kassetten jeweils mit einer zusätzlichen Öffnung versehen, durch die der gemeinsame Strang hindurchführt. Unter der untersten Kassette weist der Strang ein Widerstandselement in Gestalt eines Knicks am unteren Ende des Strangs auf. Nachteilig bei dieser Lösung ist, dass die Kassetten zum Hindurchführen des Strangs eigenständige, allein diesem Zweck dienende Öffnungen aufweisen. Durch die separaten Öffnungen verkleinert sich die Grundfläche, die für Präparate für Laboranalysen zur Verfügung steht.From the US 2005/0152809 A1 It is known to arrange on a stack arranged cassettes, which may be provided in each case with a printable label field, thread onto a common strand. For this purpose, the cassettes are each provided with an additional opening through which passes the common strand. Under the lowermost cassette, the strand has a resistance element in the form of a bend at the lower end of the strand. A disadvantage of this solution is that the cassettes for passing the strand have independent, serving solely for this purpose openings. The separate openings reduce the footprint available for preparations for laboratory analysis.

Bei der US 2013/0224088 A1 sind die zu einem Stapel angeordneten Kassetten jeweils an einem Stab befestigt, der seinerseits an einem Drucker befestigt ist. Der Stab ist durch seitliche Ausnehmungen in den Längswänden der Kassetten hindurchführt. Auch bei dieser Lösung ist die Verkleinerung der Grundfläche der Kassetten von Nachteil, da die für die formschlüssige Verbindung zu dem Stab erforderlichen Ausnehmungen Fläche beanspruchen. Die verbleibende Grundfläche ist asymmetrisch, was bei bestimmten Formen von Präparaten nachteilig sein kann.In the US 2013/0224088 A1 The arranged in a stack cassettes are each attached to a rod, which in turn is attached to a printer. The rod passes through lateral recesses in the longitudinal walls of the cassettes. Even with this solution, the reduction of the footprint of the cassette is disadvantageous, since the required for the positive connection to the rod recesses claim area. The remaining footprint is asymmetric, which can be detrimental to certain forms of preparations.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einem derartigen Kassettenstapel Maßnahmen vorzuschlagen, welche unter Wahrung des Grundaufbaus und insbesondere der Grundfläche der einzelnen Kassetten die Handhabung des Kassettenstapels, insbesondere im Rahmen des Druckvorgangs und dessen Vorbereitung, einfach halten.The invention is therefore based on the object to propose measures in such a stack of cartridges that keep the handling of the cartridge stack, especially in the context of the printing process and its preparation, while maintaining the basic structure and in particular the base of the individual cartridges.

Zur Lösung dieser Aufgabe wird ein Kassettenstapel mit den Merkmalen des Anspruchs 1 vorgeschlagen.To solve this problem, a cassette stack with the features of claim 1 is proposed.

Diese technische Lösung ermöglicht es, beim Einführen des Kassettenstapels in z. B. einen Druckerschacht oder ein Kassettenmagazin den gesamten Kassettenstapel nur an dem gemeinsamen Strang zu halten und zu tragen. Eine weitergehende Verbindung jeder einzelnen Kassette mit dem Strang, etwa durch Klebekräfte oder durch einzelne Schweißpunkte, ist nicht notwendig und vor allem nicht sinnvoll. Insbesondere erfolgt in Stranglängsrichtung keine Befestigung der einzelnen Kassetten an dem Strang. Es wird die Möglichkeit geschaffen, direkt nach dem Einführen des Kassettenstapels in den Schacht und ohne umgreifen zu müssen, lediglich durch ein verstärktes Ziehen an dem Strang nach oben und unter gleichzeitiger Ausübung von Gegendruck auf die oberste Kassette, beispielweise mit der anderen Hand, den Strang nach oben aus den Öffnungen oder Aussparungen sämtlicher Kassetten herauszuziehen. Mit einer einzigen Bewegung, dem Herausziehen des Strangs, sind die Kassetten unverzüglich vereinzelt.This technical solution makes it possible when inserting the cassette stack in z. As a printer tray or a cassette magazine to hold the entire cassette stack only on the common strand and carry. A further connection of each cassette with the strand, such as by adhesive forces or by individual welds, is not necessary and, above all, not useful. In particular, there is no attachment of the individual cassettes to the strand in the longitudinal direction of the strand. It creates the possibility, right after the insertion of the cassette stack in the slot and without having to go around, only by an increased pulling on the strand up and while exerting pressure on the topmost cassette, for example, with the other hand to pull the strand up out of the openings or recesses of all cassettes. With a single movement, pulling out the strand, the cassettes are immediately separated.

Eine Seitenwand der Kassette weist ein bedruckbares Beschriftungsfeld auf, und die Öffnung oder Aussparung ist im Bereich dieser Seitenwand angeordnet, wobei die Seitenwand eine Doppelwand ist und sich zusammensetzt aus einer Außenwand, die das bedruckbare Beschriftungsfeld aufweist, und einer Innenwand. Die Öffnung oder Aussparung wird durch den Zwischenraum zwischen den beiden Wänden gebildet. Die Öffnung oder Aussparung ist ferner ein Verrastelement zum Verschließen der Kassette mittels eines Deckels. Die Öffnung oder Aussparung hat somit eine Doppelfunktion. Einerseits bietet sie Platz für das Hindurchführen des Strangs, andererseits ist sie Teil einer Schließvorrichtung für einen Deckel der Kassette. Es kann daher eine zum Verschließen der Kassette ohnehin bestehende Öffnung oder Aussparung gleichzeitig als Durchführung für den Strang genutzt werden, so dass keine zusätzlichen konstruktiven Maßnahmen an der Kassette erfolgen müssen.A side wall of the cassette has a printable label area, and the opening or recess is located in the area of that side wall, the side wall being a double wall and composed of an outer wall having the printable label area and an inner wall. The opening or recess is formed by the space between the two walls. The opening or recess is also a latching element for closing the cassette by means of a lid. The opening or recess thus has a double function. On the one hand, it provides space for the passage of the strand, on the other hand, it is part of a closing device for a cover of the cassette. It can therefore be used simultaneously as a passage for the strand for closing the cassette anyway existing opening or recess, so that no additional design measures must be made to the cassette.

Mit einer Ausgestaltung wird vorgeschlagen, dass das Widerstandselement ein Querelement am unteren Ende des Strangs ist. Durch das Querelement wird verhindert, dass der Strang bereits bei dem Versuch, den Kassettenstapel zu tragen oder anzuheben, aus den Öffnungen oder Aussparungen des Kassettenstapels herausgezogen wird.With an embodiment, it is proposed that the resistance element is a transverse element at the lower end of the strand. The cross member prevents the strand from being pulled out of the openings or recesses of the cassette stack already in an attempt to support or lift the cassette stack.

Mit einer weiteren Ausgestaltung wird vorgeschlagen, dass das Widerstandselement ein gegenüber dem übrigen Strangverlauf verformter Endabschnitt des Strangs ist. Als Widerstandselement wird daher kein zusätzliches Bauteil benötigt.In a further embodiment, it is proposed that the resistance element is an end section of the strand which is deformed with respect to the remaining strand path. As a resistance element therefore no additional component is needed.

Eine besonders einfache Möglichkeit, den Strang selbst als Widerstandselement einzusetzen, ist es, wenn das Widerstandselement ein gegenüber dem übrigen Strangverlauf abgewinkelter Endabschnitt des Strangs ist. Damit sämtliche Einzelkassetten des Kassettenstapels über einen einzigen Strang anhebbar sind, ist der abgewinkelte Endabschnitt vorzugsweise gegen die Unterseite der untersten Kassette abgestützt.A particularly simple way to use the strand itself as a resistance element, it is when the resistance element is an opposite end of the strand angled end portion of the strand. So that all individual cassettes of the cassette stack can be raised via a single strand, the angled end section is preferably supported against the underside of the lowermost cassette.

Mit einer weiteren Ausgestaltung wird vorgeschlagen, dass der Strang ein vorzugsweise aus Kunststoff bestehendes Flachband ist, und dass die Öffnung oder Aussparung zur Aufnahme des Flachbandes von länglichem Querschnitt ist. Ein derartiges Flachband lässt sich gut in eine entsprechend schlitzförmige Öffnung oder Aussparung in den Kassetten einfädeln.With a further embodiment, it is proposed that the strand is a preferably made of plastic ribbon, and that the opening or recess for receiving the flat strip is of elongated cross-section. Such a ribbon can be well threaded into a corresponding slot-shaped opening or recess in the cassette.

Mit einer weiteren Ausgestaltung wird vorgeschlagen, dass die Innenwand rechtwinklig, und die Außenwand unter Bildung eines V-Winkels schräg zu dem Boden der Kassette angeordnet ist. Diese Anordnung ist von großem Vorteil beim Einführen des Strangs.With a further embodiment, it is proposed that the inner wall is arranged at right angles, and the outer wall is arranged at an angle to the bottom of the cassette with the formation of a V-angle. This arrangement is of great advantage when inserting the strand.

Eine weitere Vereinfachung der Handhabung des Kassettenstapels wird durch eine gut von Hand greifbare Schlaufe am oberen Ende des Strangs erzielt. Vorzugsweise ist die Schlaufe aus dem Material des Strangs geformt. Diese Ausgestaltung ermöglicht es, aus einem konventionellen Flachband ohne zusätzliche Elemente einen Strang mit Schlaufe und Querelement zu fertigen.Further simplification of the handling of the cartridge stack is achieved by a good hand-grip loop at the top of the string. Preferably, the loop is formed from the material of the strand. This embodiment makes it possible to produce a strand with a loop and cross member from a conventional ribbon without additional elements.

Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung dreier Ausführungsbeispiele, wobei auf die Zeichnungen Bezug genommen wird. Darin zeigen:

Figur 1 zeigt in einer Schnittdarstellung eine Seitenansicht eines Kassettenstapels, während dieser von oben her in einen Druckerschacht 4 eines für das Bedrucken der Kassetten geeigneten Druckers eingeführt wird. Der Schnitt verläuft mittig durch die auf einen gemeinsamen Strang 8 aufgefädelten Kassetten 2. FIG. 1 shows in a sectional view a side view of a cassette stack while it is introduced from above into a printer shaft 4 of a printer suitable for printing on the cartridges. The section runs centrally through the threaded onto a common strand 8 cassettes. 2

Die Darstellung Fig. 1 ist ferner zweifach unterbrochen. Im untersten Teil sind die bereits in den Druckerschacht 4 eingeführten Kassetten 2 ersichtlich. Der Grund 10 des Druckerschachtes 4 sowie seine Ausdehnung in Längsrichtung der Kassetten 2 ist derart ausgestaltet, dass die eingeführten Kassetten 2 in einer gewissen Schrägstellung von etwa 20° aufliegen.The representation Fig. 1 is also interrupted twice. In the bottom part of the already introduced into the printer tray 4 cassettes 2 are visible. The base 10 of the printing tray 4 and its extension in the longitudinal direction of the cassette 2 is designed such that the inserted cassettes 2 rest in a certain inclination of about 20 °.

Der mittlere und der obere Teil der Fig. 1 zeigt den soeben von oben her eingeführten Kassettenstapel mit den auf dem Strang 8 aufgefädelten Kassetten 2, einer Schlaufe 12 am oberen Ende des Strangs 8 sowie einem Widerstandselement 14 am unteren Ende. Dieses ist als ein abgewinkelter Endabschnitt des Strangs 8 ausgestaltet, der sich unterhalb des Bodens 16 der untersten Kassette 2 des Kassettenstapels befindet, und von unten her gegen diesen Boden 16 abgestützt ist.The middle and the upper part of the Fig. 1 shows the cassette stack just introduced from above with the cassettes 2 threaded on the strand 8, a loop 12 at the upper end of the strand 8 and a resistance element 14 at the lower end. This is designed as an angled end portion of the strand 8, which is located below the bottom 16 of the bottom cassette 2 of the cassette stack, and is supported from below against this bottom 16.

Dadurch, dass die Kassetten 2 durch den als Flachband ausgeführten Strang 8 nur lose aufgefädelt miteinander verbunden sind und sie nicht einzeln an dem Strang befestigt sind, können die Kassetten 2 beim Einführen in den Schacht 4 selbstfindend in die für das Bedrucken vorteilhafte Schrägstellung gelangen. Während sämtliche Kassetten 2 des oberen Teils der Darstellung im Wesentlichen noch waagerecht aufeinandergestapelt sind, ändert sich dies in dem mittleren Teil von Figur 1 von oben nach unten zunehmend, so dass die untersten Kassetten 2 die gewünschte Schrägstellung einnehmen.Due to the fact that the cassettes 2 are connected to one another only loosely threaded together by the strand 8 designed as a flat strip and that they are not fastened individually to the strand, the cassettes 2 can enter into the inclined position advantageous for printing when they are introduced into the shaft 4. While all the cassettes 2 of the upper part of the illustration are stacked substantially horizontally yet, changes this in the middle part of FIG. 1 Increasing from top to bottom, so that the bottom cassettes 2 take the desired inclination.

In Figur 2 ist nur der Kassettenstapel aus Figur 1 dargestellt, wobei in einem oberen Teilschnitt zu sehen ist, wie der Strang 8 innerhalb des Kassettenstapels zwar durch sämtliche Kassetten 2 hindurchgeführt ist, ohne dass jedoch die einzelnen Kassetten in Stranglängsrichtung an dem Strang 8 befestigt sind. In Figur 2 nicht erkennbare Öffnungen 18 der Kassetten 2 werden im Folgenden noch näher beschrieben.In FIG. 2 is just the cartridge stack off FIG. 1 represented, wherein in an upper partial section can be seen how the strand 8 is passed through all the cassettes 2 within the cassette stack, but without the individual cassettes are fixed in the strand longitudinal direction of the strand 8. In FIG. 2 unrecognizable openings 18 of the cassettes 2 will be described in more detail below.

Ein unterer Teilschnitt in Fig. 2 sowie die Fig. 3 zeigt, wie der Strang 8 unterhalb der untersten Kassette 2 an einer Abwinklung 28 rechtwinklig abgeknickt ist, so dass der abgewinkelte Längsabschnitt das quer zu dem übrigen Strang angeordnete Widerstandselement 14 bildet. Dabei stützt sich der abgewinkelte Endabschnitt des Strangs 8 gegen den Boden 16 bzw. gegen die Unterseite 20 der untersten Kassette 2 ab, und stützt so sämtliche Kassetten 2 des Kassettenstapels.A lower part section in Fig. 2 as well as the Fig. 3 shows how the strand 8 is bent at right angles below the lowest cassette 2 at an angled portion 28, so that the angled longitudinal portion forms the resistance element 14 arranged transversely to the rest of the strand. In this case, the angled end portion of the strand 8 is supported against the bottom 16 and against the bottom 20 of the lowermost cassette 2, and thus supports all the cassettes 2 of the cassette stack.

Jede Kassette 2 besteht aus einem perforierten Boden 16 und Seitenwänden 24. Die Perforationen können Löcher 22 oder andere Durchbrüche beliebiger Form sein.Each cassette 2 consists of a perforated bottom 16 and side walls 24. The perforations may be holes 22 or other apertures of any shape.

Die in den Figuren 1 bis 3 jeweils links dargestellte Seitenwand ist eine Doppelwand 23 und besteht aus einer Innenwand 25 und einer Außenwand 26, welche gleichzeitig als ein bedruckbares Beschriftungsfeld 26 dient. Während die Innenwand 25 rechtwinklig zum Boden 16 angeordnet und direkt mit diesem verbunden ist, verläuft die Außenwand 26 schräg in einem Winkel auf den oberen Rand der Innenwand 25 zu. Dort wo sich die Innenwand 25 und die Außenwand 26 V-förmig treffen, ist auf der Mitte der Breite der Kassette eine schlitzförmige Öffnung 18 zum Hindurchführen des Flachbandes 8 angeordnet. Die Länge und Breite der Öffnung 18 korrespondiert dabei mit dem entsprechenden Querschnitt des Flachbands 8.The in the FIGS. 1 to 3 each side wall shown on the left is a double wall 23 and consists of an inner wall 25 and an outer wall 26, which also serves as a printable labeling field 26. While the inner wall 25 is disposed at right angles to the floor 16 and connected directly thereto, the outer wall 26 extends obliquely at an angle to the upper edge of the inner wall 25. Where the inner wall 25 and the outer wall 26 meet V-shaped, a slot-shaped opening 18 for passing the flat strip 8 is arranged on the middle of the width of the cassette. The length and width of the opening 18 corresponds to the corresponding cross section of the flat belt eighth

Für eine möglichst horizontale Ausrichtung der nur durch den Strang 8 gehaltenen Kassetten 2 ist es von Vorteil, dass sich jeweils die Innenwand 25 mit ihrer der Außenwand 26 zugewandten Seite unmittelbar gegen den Strang 8 abstützt, also insbesondere gegen die Breitseite des Strangs 8.For a possible horizontal alignment of only held by the strand 8 cassettes 2, it is advantageous that in each case the inner wall 25 is supported with its outer wall 26 side facing directly against the strand 8, ie in particular against the broad side of the strand. 8

Die Abwinklung 28 des aus Kunststoff bestehenden Flachbands 8 weist eine derartige Steifigkeit auf, dass sie die Gewichtskraft der auf dem Flachband 8 aufgefädelten Kassetten 2 ohne größere Verformung aufnehmen kann. Wird jedoch nach dem Absenken des Stapels in den Druckerschacht 4 durch Ziehen an der Schlaufe 12 ein gewisser zusätzlicher Druck auf die Abwinklung ausgeübt, gibt die Abwinklung 28 so stark nach, dass nach Überwinden dieses anfänglichen Widerstands der Strang 8 nach oben hin aus den Kassetten 2 herausgezogen werden kann. Der zusätzliche Druck wird durch Ziehen an der Schlaufe 12 des Flachbandes 8 nach oben, unter gleichzeitigem Druck nach unten auf die oberste Kassette 2 des Kassettenstapels erzeugt.The angled portion 28 of the plastic flat strip 8 has such rigidity that it can absorb the weight of the threaded on the flat strip 8 cassettes 2 without major deformation. However, after lowering the stack in exerted the printer shaft 4 by pulling on the loop 12, a certain additional pressure on the bend, the bend 28 so much that after overcoming this initial resistance of the strand 8 can be pulled upwards out of the cassette 2. The additional pressure is generated by pulling on the loop 12 of the ribbon 8 upwards, with simultaneous downward pressure on the topmost cassette 2 of the cassette stack.

Je nach Beschaffenheit der Kassetten 2 bzw. deren Anzahl innerhalb eines als Ganzes einzuführenden Kassettenstapels können die Geometrien, d. h. insbesondere die Breite der Öffnung 18 und die Länge des abgewinkelten Endabschnitts 30 des Flachbandes 8, aufeinander abgestimmt werden.Depending on the nature of the cassettes 2 or their number within a cassette stack to be introduced as a whole, the geometries, i. H. in particular, the width of the opening 18 and the length of the angled end portion 30 of the flat strip 8, are coordinated.

Die Figur 4 zeigt eine zweite Ausführungsform eines Kassettenstapels in perspektivischer Darstellung, bei der jede Kassette 2 zusätzlich einen Deckel 34 aufweist. Der Deckel 34 kann wie dargestellt über ein Gelenk 32 mit der der Doppelwand 23 gegenüberliegenden Seitenwand 24 der Kassette 2 verbunden sein, oder die Verbindung zwischen Kassettengrundkörper und Deckel erfolgt über ein Filmscharnier oder eine Sollbruchstelle.The FIG. 4 shows a second embodiment of a cassette stack in a perspective view, in which each cassette 2 additionally has a cover 34. As shown, the cover 34 can be connected via a hinge 32 to the side wall 24 of the cassette 2 opposite the double wall 23, or the connection between the cassette base body and the lid takes place via a film hinge or a predetermined breaking point.

Zum Verschließen der Kassette 2 greift der Deckel 34 auf seiner dem Gelenk 32 abgewandten Seite nach dem Snap-Lock-Prinzip mittels eines hakenförmigen Verrastelements 36 in die Öffnung 18 ein. Die Öffnung 18 fungiert insofern ebenfalls als Verrastelement 38.To close the cassette 2, the lid 34 engages on its side facing away from the hinge 32 according to the snap-lock principle by means of a hook-shaped latching element 36 in the opening 18 a. The opening 18 also acts as a latching element 38.

Die Figuren 5 und 6 zeigen das Verfahren des Einführens des Flachbandes 8 in den Kassettenstapel und des Umformens des oberen Strangendes zu einer Schlaufe 12.The FIGS. 5 and 6 show the process of inserting the ribbon 8 into the stack of cassettes and reshaping the top strand to form a loop 12.

Das Flachband 8 wird mit seinem vorderen Ende zuerst von der Unterseite der Kassetten her in den Kassettenstapel eingeschoben. Der Kassettenstapel ist hierbei in einer Position fixiert, in der die Öffnungen 18 der einzelnen Kassetten zueinander fluchten. Dabei bilden die zwei von der Unterseite der Kassetten her V-förmig aufeinander zu laufenden Wände 25 und 26 einen zu der schlitzförmigen Öffnung 18 hin sich verengenden Trichter, der das Einführen und dann Weiterführen des Stranganfangs von Kassette zu Kassette erheblich vereinfacht, so dass es ausreicht, den Strang 8 an seinem hinteren Ende vorwärts zu schieben.The ribbon 8 is inserted with its front end first from the bottom of the cassette ago in the cassette stack. The cassette stack is in this case fixed in a position in which the openings 18 of the individual cassettes are aligned with each other. The two form from the bottom of the cassette forth V-shaped running walls 25 and 26 to the slot-shaped opening 18 towards narrowing funnel, which greatly simplifies the insertion and then continue the Stranganfangs from cassette to cassette, so that it is sufficient to push the strand 8 forward at its rear end.

Der vordere Abschnitt des Flachbands gelangt, nachdem alle Kassetten durchlaufen wurden, in eine ortsfest angeordnete Schikane 40, die von dem Flachband 8 um ca. 180° durchlaufen wird, wodurch die Schlaufe 12 geformt wird. Die Schlaufenenden werden dann verbunden, zum Beispiel durch Heißverpressen.The front portion of the flat belt, after all the cassettes have been passed through, arrives in a fixedly arranged chicane 40, which passes from the flat strip 8 through approximately 180 ° becomes, whereby the loop 12 is formed. The loop ends are then connected, for example by hot pressing.
