Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöstThis object is solved by the features of claim 1

Vorteilhafte Ausgestaltungen der vorliegenden Erfindung sind mit den Unteransprüchen angegeben.Advantageous embodiments of the present invention are specified by the subclaims.

Grundgedanke der Erfindung ist der Einsatz einer Darreichungseinheit für eine knetbare Masse umfassend ein zu einer Rolle gewickeltes Band an knetbarer Masse bestehend aus zumindest zwei Komponenten und einen Spender aufweisend eine Halterungsinöglichkeit für die um eine Achse drehbare Rolle, um über eine Drehung der Rolle eine Abwicklung des Bandes zu ermöglichen, und mit einer Abtrennvorrichtung zum Abtrennen eines abgewickelten Teilstückes des Bandes.The basic idea of the invention is the use of a dispensing unit for a kneadable mass comprising a wound into a roll band of kneadable mass consisting of at least two components and a dispenser having a holding possibility for the rotatable about an axis roller to a rotation of the roll a settlement of Bandes allow, and with a separating device for separating a developed portion of the tape.

Als knetbare Masse kann dabei insbesondere ein knetbarer Klebstoff auf Epoxidharz-Basis zum Einsatz kommen. Denkbar können auch Polyurethan-Kunstharzsysteme oder radikalisch härtende Kunstharzsysteme sein. Derartige knetbare Massen können beispielsweise im Baubereich als Befestigungsmassen zu Anwendung kommen, insbesondere als Kleber für Verankerungselemente. Zudem können Fehlstellen und Löcher in einer Vielzahl von Materialien ausgebessert werden. In der Regel weisen derartige knetbare Massen zumindest zwei Komponenten auf, die durch Kneten miteinander vermischt werden, insbesondere um eine Reaktion zur Aushärtung der Masse zu erreichen.As a kneadable mass can be used in particular a kneadable epoxy resin-based adhesive. Also conceivable may be polyurethane resin systems or radically curing resin systems. Such kneadable masses can be used, for example, in the construction sector as fixing compounds, in particular as an adhesive for anchoring elements. In addition, defects and holes can be repaired in a variety of materials. In general, such kneadable masses on at least two components by Kneading are mixed together, in particular to achieve a reaction to cure the mass.

Vorzugsweise ist die knetbare Masse in der vorliegenden Erfindung derartig als Band gestaltet, dass die miteinander zu verknetenden Komponenten nebeneinander oder übereinander oder eine Kombination hieraus vorliegen, insbesondere als Coextrudat. Besonders bevorzugt weist das Band über vorzugsweise seine gesamte Lange im Schnitt orthogonal zur Längserstreckung des Bandes immer dasselbe Verhältnis der Komponenten zueinander auf, um eine gleichmäßige Zusammensetzung der Masse zu erhalten.Preferably, the kneadable composition in the present invention is designed as a band in such a way that the components to be kneaded together are next to or above each other or a combination thereof, in particular as coextrudate. Particularly preferably, the band over preferably its entire length in the section orthogonal to the longitudinal extent of the band always the same ratio of the components to each other in order to obtain a uniform composition of the mass.

Im vorliegenden Fall ist das Band zudem als Rolle aufgewickelt, beispielsweise um einen möglichst geringen Raum zur Lagerung zu beanspruchen. Dabei kann vorgesehen werden, dass zwischen den einzelnen Lagen des zu einer Rolle aufgerollten Bandes ein Trennmittel, insbesondere ein chemisches Trennmittel und/ oder eine Trenn- oder Deckfolle vorgesehen ist, um ein Anhaften einer Lage des Bandes an einer benachbarten Lage auf der Rolle zu verhindern.In the present case, the tape is also wound up as a roll, for example to claim the smallest possible space for storage. It can be provided that between the individual layers of the rolled-up to a roll strip a release agent, in particular a chemical release agent and / or a release or cover foil is provided to prevent adhesion of a layer of the tape to an adjacent layer on the roll ,

Um eine einfache Lagerung der Rolle und insbesondere eine einfache Entnahmemöglichkeit der knetbaren Masse zu ermöglichen ist erfindungsgemäß ferner ein Spender vorgesehen. Der Spender ist dabei mit einer Halterungsmöglichkeit ausgestattet, die die Aufnahme der Rolle ermöglicht und zudem eine Drehung der Rolle zum Abrollen des Bandes erlaubt. Hierzu kann insbesondere eine Drehachse vorgesehen werden, auf die die Rolle aufgebracht werden kann. Denkbar ist zudem die Vorsehung einer Spule, auf der das Band zur Bereitstellung der Rolle aufgerollt ist, wobei die Spule derart in den Spender eingelegt oder eingespannt werden kann, dass eine sichere Fixierung einerseits, andererseits jedoch eine Drehung der Spule und somit der Roller möglich ist. Demnach kann ein beliebiges Teilstück durch Drehung der Rolle von selbiger abgewickelt werden.In order to enable a simple storage of the role and in particular a simple removal possibility of the kneadable mass, a dispenser according to the invention is further provided. The dispenser is equipped with a mounting possibility that allows the inclusion of the role and also allows rotation of the roll to unwind the tape.

Zum Abtrennen dieses Teilstückes des Bandes ist der Spender dabei mit einer Abtrennvorrichtung ausgestattet. Die Abtrennvorrichtung kann dabei vorzugsweise Schneid- oder Stechmittel in einer beliebigen Form aufweisen, die es ermöglicht, ein Abtrennen des besagten Teilstückes zu gewährleisten. In der Praxis kann dabei eine Entnahme des Teilstückes derart erfolgen, dass der Anwender auf ein vorstehendes Ende des Bandes eine Zugkraft ausübt, was eine Drehung der Rolle und eine Abwicklung des Bandes von der Rolle zur Folge hat. Nach der Bereitstellung eines Teilstückes mit einer gewünschten Länge kann der Anwender selbiges durch Bewegung des Teilstückes in Richtung der Abtrennvorrichtung derart, dass beispielsweise die Schneld- oder Stechmittel in das Band einschneiden und/oder einstechen, abtrennen. Durch Kneten des abgetrennten Teilstückes kann der Anwender sodann seine fertige und zu verarbeitende Masse erhalten.To separate this section of the tape, the dispenser is equipped with a separating device. The separating device may preferably have cutting or lancing means in any desired shape, which makes it possible to ensure separation of the said section. In practice, a removal of the section can take place in such a way that the user exerts a pulling force on a projecting end of the strip, which results in a rotation of the roll and a unwinding of the strip from the roll. After providing a section of a desired length, the user can detach the same by moving the section in the direction of the separating device such that, for example, the quick or piercing means cut and / or pierce the strip. By kneading the severed Section, the user can then receive his finished and processed mass.

Mit der erfindungsgemäßen Darreichungseinheit erhält der Anwender demnach beispielsweise einen Vorrat an knetbarer Masse, wobei jederzeit beliebige Teilstücke entnehmbar sind. Der Spender stellt einerseits eine Lagermöglichkeit der knetbaren Masse bereit, andererseits wird dem Anwender ein einfaches Arbeitsmittel an die Hand gegeben, um ein beliebiges Teilstück an knetbarer Masse von dem Vorrat abtrennen zu können.With the dispensing unit according to the invention, the user thus receives, for example, a supply of kneadable mass, wherein arbitrary portions can be removed at any time. On the one hand the dispenser provides a storage possibility of the kneadable mass, on the other hand the user is provided with a simple working medium to be able to separate any portion of kneadable mass from the supply.

Mit einem derartigen Spender kann eine besonders sichere Lagermöglichkeit für die knetbare Masse bereitgestellt werden, um beispielsweise die knetbare Masse vor Umwelteinflüssen oder Verschmutzung zu schützen.In an advantageous development of the present invention, it is further provided that the dispenser has a substantially closed housing having a cavity for receiving the roller, wherein an output opening for removing a portion of the tape is provided, wherein in the region of the dispensing opening, the separating device is arranged. With such a dispenser, a particularly secure storage facility for the kneadable mass can be provided to protect, for example, the kneadable mass from environmental influences or contamination.

Ein weiterer Vorteil ist die Ausstattung zumindest einer Seite des Bandes mit einer Deckfolie, wobei das Band derart zu einer Rolle gewickelt ist und/oder die Abtrennvorrichtung derart hinsichtlich des abgewickelten Bandes angeordnet ist, dass die Abtrennvorrichtung der Deckfolie des Bandes oder des Teilstückes des Bandes direkt gegenüberliegend angeordnet ist, um einen direkten Eingriff der Abtrennvorrichtung in die Deckfolie zum Abtrennen eines Teilstückes des Bandes zu ermöglichen. In einer vorteilhaften Weiterbildung ist zumindest eine weitere Deckfolie vorgesehen, die eine weitere sich in Richtung des abgerollten Bandes, also in eine Entnahmerichtung erstreckende Seite des Bandes abdeckt. Denkbar ist zudem der Einsatz einer Deckfolie an allen sich in Entnahmerichtung erstreckenden Seiten.Another advantage is the equipment at least one side of the tape with a cover sheet, wherein the tape is wound into a roll and / or the separating device is arranged with respect to the unwound tape, that the separating device of the cover sheet of the tape or the piece of tape directly is disposed opposite to allow a direct engagement of the separating device in the cover sheet for separating a portion of the tape. In an advantageous development, at least one further covering film is provided which covers another side of the band extending in the direction of the unwound strip, that is to say in a withdrawal direction. It is also conceivable the use of a cover sheet on all in the removal direction extending sides.

In einer vorteilhaften Weiterbildung kann die Abtrennvorrichtung eine Klinge oder ein Messer oder ein oder mehrere vorstehende Domen umfassen. Besonders bevorzugt kommt jedoch eine Darreichungseinheit zum Einsatz, wobei die Abtrennvorrichtung des Spenders eine Vielzahl von in Entnahmerichtung des Bandes oder des Teilstückes des Bandes vorstehenden und nebeneinander im Wesentlichen quer oder orthogonal zur Entnahmerichtung angeordneten Schneidmitteln, insbesondere Schneidzahnen aufweist. Vorzugsweise ist die Abtrennvorrichtung dabei im Wesentlichen orthogonal zur Entnahmerichtung des Bandes angeordnet. Bevorzugt ist die Abtrennvorrichtung zumindest so breit wie das abzurollende Band, besonders bevorzugt jedoch breiter, um eine Abtrennung eines Teilstückes zu ermöglichen.In an advantageous development, the separating device may comprise a blade or a knife or one or more protruding domes. However, a dispensing unit is particularly preferably used, wherein the separating device of the dispenser has a multiplicity of cutting means, in particular cutting teeth, projecting in the removal direction of the band or the portion of the band and arranged side by side substantially transversely or orthogonally to the withdrawal direction. Preferably, the separating device is arranged substantially orthogonal to the removal direction of the tape. Preferably, the separating device is at least as wide as the tape to be unrolled, but particularly preferably wider, to allow a separation of a section.

Ein weiterer Vorteil ist der Einsatz einer Abtrennvorrichtung, welches ein Schneidmittel in Form mindestens eines Schneidzahns aufweist, der zumindest eine Zahnspitze und zumindest einen Zahngrund beinhaltet, wobei der Schneidzahn zudem eine Zahnhöhe aufweist, die die Stärke der Deckfolie übersteigt. Eine derartige Ausbildung der Abtrennvorrichtung macht insbesondere bei einer derartigen Gestaltung der Darreichungseinheit Sinn, bei der zumindest eine Seite des Bandes mit einer Deckfolie versehen ist, wobei das Band derart zu einer Rolle gewickelt ist und/oder die Abtrennvorrichtung derart hinsichtlich des abgewickelten Bandes angeordnet ist, dass die Abtrennvorrichtung der Deckfolie des Bandes oder des Teilstückes des Bandes direkt gegenüberliegend angeordnet ist, um einen direkten Eingriff der Abtrennvorrichtung in die Deckfolie zum Abtrennen eines Teilstückes des Bandes zu ermöglichen. Vorzugsweise ist die Abtrennvorrichtung auch hier im Wesentlichen orthogonal zur Abrollrichtung des Bandes angeordnet Bevorzugt ist die Abtrennvorrichtung zudem so breit wie das abzurollende Band, um eine Abtrennung eines Teilstückes zu ermöglichen.
Besagte Schneidspitze kann dabei der dem gegenüberliegenden Band oder der gegenüberliegenden Deckfolie am nächsten liegende Bereich eines Schneidzahns sein, wobei der Zahngrund wiederum der dem gegenüberliegenden Band oder der gegenüberliegenden Deckfolie am weitesten entfernte Teil eines Schneidzahns sein kann. Die Zahnhöhe stellt dabei vorzugsweise den Abstand des Niveaus der Zahnspitze zu Niveau des Zahngrunds dar.Another advantage is the use of a severing device which has a cutting means in the form of at least one cutting tooth, which includes at least one tooth tip and at least one tooth root, wherein the cutting tooth also has a tooth height that exceeds the thickness of the cover sheet. Such a design of the separating device makes sense, in particular in such a configuration of the presentation unit, in which at least one side of the band is provided with a cover film, the band being wound into a roll in such a way and / or the separating device is arranged with respect to the unwound band, in that the separating device is arranged directly opposite the covering film of the band or of the part of the band, in order to allow a direct engagement of the separating device in the covering film for the separation of a section of the band. Preferably, the severing device is arranged here also substantially orthogonal to the unwinding direction of the belt. In addition, the severing device is preferably as wide as the strip to be unrolled in order to enable a separation of a section.
Said cutting tip can be the region of a cutting tooth closest to the opposite band or the opposite cover foil, wherein the tooth root can again be the part of a cutting tooth farthest from the opposite band or cover foil. The tooth height preferably represents the distance of the level of the tooth tip to the level of the tooth base.

Ein weiterer Vorteil kann die Ausstattung der Abtrennvorrichtung mit einem Schneidmittel in Form mindestens eines Schneidzahns sein, wobei der Schneidzahn eine Zahnhöhe aufweist, die zumindest halb so lang ist, wie die Starke des Bandes, um eine Abtrennung des abgewickelten Teilstückes des Bandes zu gewährleisten.Another advantage may be the equipment of the separating device with a cutting means in the form of at least one cutting tooth, wherein the cutting tooth has a tooth height which is at least half as long as the strength of the tape to ensure a separation of the unwound portion of the tape.

In einer vorteilhaften Weiterbildung kann die Abtrennvorrichtung ein Schneidmittel in Form mindestens eines Schneidzahns aufweisen aufweist, wobei zumindest ein Zahnrücken gewölbt ausgebildet ist, um eine Abtrennung des abgewickelten Teilstückes des Bandes zu gewährleisten.In an advantageous development, the separating device may have a cutting means in the form of at least one cutting tooth, wherein at least one tooth back is arched in order to ensure a separation of the unwound portion of the band.

Figur 1 zeigt eine Seitenansicht einer Darreichungseinheit 1 für eine knetbare Masse 18 bestehend aus zwei Komponenten. Selbige ist in einem Spender 2 mit einem im Wesentlichen geschlossenen Gehäuse 3 enthalten. Dabei ragt ein Teilstück 23 eines Bandes 22 der knetbaren Masse 18 durch eine Ausgabeöffnung 6 an einer Vorderseite 7 des Gehäuses 3 heraus. Innerhalb des Gehäuses 3 ist eine in Form eines Bandes 22 vorliegende knetbare Masse 18 zu einer nicht dargestellten Rolle aufgewickelt, die um eine Drehachse 4 verdrehbar innerhalb des Gehäuses 3 gelagert ist, um das Band 22 an knetbarer Masse 18 in eine Entnahmerichtung 24 abwickeln und aus der Ausgabeöffnung 6 des Spenders 2 entnehmen zu können. An der Oberseite des Bandes 22 der knetbaren Masse 18 ist selbige flachig mit einer Deckfolie 21 versehen, insbesondere um ein anhaften einer Lage der knetbaren Masse 18 im aufgerollten Zustand an einer benachbarten Lage zu vermeiden. Gleichwohl kann es sich auch als sinnvoll erweisen, einer weitere Deckfolie an der gegenüberliegenden Seite des Bandes 22 vorzusehen oder das Band 22 an allen sich in Entnahmerichtung 24 erstreckenden Seiten mittels einer Deckfolie zu versehen und insbesondere vor Umwelteinflüssen zu schützen. FIG. 1 shows a side view of a dispensing unit 1 for a kneadable mass 18 consisting of two components. The same is contained in a dispenser 2 with a substantially closed housing 3. In this case, a portion 23 of a belt 22 of the kneadable mass 18 protrudes through a discharge opening 6 on a front side 7 of the housing 3. Within the housing 3, a present in the form of a belt 22 kneadable mass 18 is wound into a roll, not shown, which is rotatably mounted about a rotation axis 4 within the housing 3 to unwind the tape 22 kneadable mass 18 in a removal direction 24 and from to be able to remove the dispensing opening 6 of the dispenser 2. At the top of the band 22 of the kneadable mass 18 selbige is flat provided with a cover sheet 21, in particular to prevent adhesion of a layer of the kneadable mass 18 in the rolled state at an adjacent position. However, it may also prove useful to provide a further cover sheet on the opposite side of the belt 22 or to provide the belt 22 at all extending in the removal direction 24 sides by means of a cover sheet and in particular to protect against environmental influences.

Figur 2 zeigt eine geschnittene Seitenansicht der Darreichungseinheit 1 aus Figur 1, wobei das im Wesentlichen geschlossene Gehäuse 3 mit der Ausgabeöffnung 6 an der Vorderseite 7 des Spenders 2 deutlich zu erkennen ist Das Band 22 an knetbarer Masse 18 ist auf eine Spule 17 aufgerollt und ist als eine innerhalb eines durch das Gehäuse 3 begrenzten Hohlraums 5 angeordnete Rolle 16 vorgesehen. Die Rolle 16 ist mit ihrer Spule 17 um die Drehachse 4 zur Abwicklung des Bandes 22 drehbar angeordnet. Im gezeigten Beispiel ist die Drehachse 4 als drehbar mit dem Gehäuse 3 verbundene Welle gestaltet, auf welche die, eine korrespondierende Bohrung aufweisende Spule 17 mit der Rolle 16 aufgeschoben worden ist. Hierfür ist das Gehäuse 3 vorzugsweise öffenbar, so dass eine Austauschmöglichkeit der Rolle 16 zur Bereitstellung einer Möglichkeit zur Wiederbefüllung des Spenders 2 denkbar ist Um das abgewickelte Band 22 in Richtung Ausgabeöffnung 6 zu führen, ist eine Leitplatte 8 aufweisend eine vorstehende Leitspitze 9 vorgesehen. Die Leitplatte 8 erstreckt sich dabei von einer Gehäuseinnenwand an der Ausgabeöffnung 6 in den Hohlraum 4 und ermöglicht eine zielgerichtete Führung des abgewickelten Bandes 22 in Richtung Ausgabeöffnung 6, insbesondere bei bereichsweise abgewickelter Rolle 16, bei der selbige einen geringeren Außendurchmesser aufweist. FIG. 2 shows a sectional side view of the delivery unit 1 from FIG. 1 in which the substantially closed housing 3 with the discharge opening 6 on the front side 7 of the dispenser 2 can be clearly seen. The band 22 of kneadable mass 18 is rolled up on a spool 17 and is arranged as one within a cavity 5 delimited by the housing 3 Roll 16 provided. The roller 16 is arranged with its coil 17 about the rotation axis 4 for unwinding the belt 22 rotatably. In the example shown, the axis of rotation 4 is configured as a shaft rotatably connected to the housing 3, on which the, a corresponding bore having coil 17 has been pushed with the roller 16. For this purpose, the housing 3 is preferably openable, so that a replacement possibility of the roller 16 to provide a possibility for refilling the dispenser 2 is conceivable to run the unwound belt 22 in the direction of the discharge opening 6, a guide plate 8 is provided having a projecting tip 9. The guide plate 8 extends from a housing inner wall to the discharge opening 6 in the cavity 4 and allows a targeted guidance of the unwound belt 22 in the direction of discharge opening 6, in particular at partially unwound roll 16, wherein the same has a smaller outer diameter.

Im Bereich der Ausgabeöffnung 6 weist der Spender 2 eine Abtrennvorrichtung in Form eines Schneidmessers 10 zum Abtrennen eines abgewickelten Teilstückes 23 des Bandes 22 auf. Das Schneidmesser 10 erstreckt sich dabei quer oder orthogonal zur Entnahmerichtung 24 über die gesamte Oberseite des Bandes 22, also direkt gegenüberliegend zu der Deckfolie 21. Während des Abwickelvorgangs des Bandes 22 ist das Schneidmesser 10 jedoch nicht zwingend mit der Deckfolie 21 oder dem Band 22 in Kontakt.In the region of the dispensing opening 6, the dispenser 2 has a severing device in the form of a cutting blade 10 for severing a unwound portion 23 of the belt 22. The cutting blade 10 extends transversely or orthogonally to the removal direction 24 over the entire top of the belt 22, that is directly opposite to the cover sheet 21. While However, the unwinding operation of the belt 22, the cutting blade 10 is not necessarily in contact with the cover sheet 21 or the belt 22.

Figur 3 zeigt eine Detailansicht A der Darreichungseinheit 1 aus Figur 2. Hier ist zu erkennen, dass die Ausgabeöffnung 6 derart bemessen ist, dass eine Entnahme oder ein Herausziehen des Bandes 22 aus der Ausgabeöffnung 6 jederzeit ohne Kontaktierung des Schneidmessers 10 möglich ist. Erst wenn ein Anwender ein gewünschtes Teilstück 23 erhält, kann selbiges durch eine Eingriffmöglichkeit des Schneidmessers 22 in die Deckfolie 21 und/oder das Band 22 von dem übrigen Band 22 separiert werden. Das Schneidmesser 10 ist im gezeigten Ausführungsbeispiel als Teil des Gehäuses 3 an selbiges angeformt und besteht aus demselben Material wie das Gehäuse 3. Gleichwohl kann es denkbar sein, das Schneidmesser aus einem anderen Material, insbesondere aus einem metallischen Werkstoff herzustellen und durch eine geeignete Befestigungstechnik mit dem Gehäuse 3 zu verbinden. Das Schneidmesser 10 weist eine Vielzahl von in einer Reihe nebeneinander angeordneten Schneidzähnen 11 auf, deren Zahnspitzen 13 in Richtung Deckfolie 21 des Bandes weisen. Bei der gezeigten Darreichungseinheit 1 kann eine Entnahme eines Teilstückes 23 beispielsweise folgendermaßen erfolgen. Der Anwender greift das Band 22 an knetbarer Masse 18 an dem aus der Ausgabeöffnung 6 vorstehenden Teilstück 23 an und wickelt das Band 22 durch Ausübung einer Zugkraft auf das Teilstück 23 in die Entnahmerichtung 24 ab, bis ein Teilstück 23 der gewünschten Länge vorliegt. So dann kann der Anwender das Teilstück 23 durch eine Aufwärtsbewegung des Bandes 22 in Richtung Schneidmesser 10, bis selbiges in die Deckfolie 10 und gegebenenfalls in die knetbare Masse 18 eingreift, durch das Schneidmesser 10 vom Band 22 abtrennen. FIG. 3 shows a detailed view A of the delivery unit 1 from FIG. 2 , Here it can be seen that the discharge opening 6 is dimensioned such that a removal or withdrawal of the belt 22 from the discharge opening 6 at any time without contacting the cutting blade 10 is possible. Only when a user receives a desired section 23, the same can be separated by an intervention possibility of the cutting blade 22 in the cover sheet 21 and / or the band 22 of the rest of the band 22. The cutting blade 10 is formed in the embodiment shown as part of the housing 3 to the same and is made of the same material as the housing 3. Nevertheless, it may be conceivable to make the cutting blade of a different material, in particular of a metallic material and by a suitable fastening technology to connect the housing 3. The cutting blade 10 has a plurality of juxtaposed cutting teeth 11 in a row, the tooth tips 13 point in the direction of cover sheet 21 of the tape. In the dispensing unit 1 shown, a removal of a section 23 can take place, for example, as follows. The user engages the tape 22 to kneadable mass 18 at the projecting from the output port 6 section 23 and winds the tape 22 by exerting a tensile force on the portion 23 in the removal direction 24 until a portion 23 of the desired length is present. So then the user can the section 23 by an upward movement of the belt 22 in the direction of cutting blade 10 until the same engages the cover sheet 10 and optionally in the kneadable mass 18, separated by the cutting blade 10 from the belt 22.

Figur 4 zeigt einen Ausschnitt einer Draufsicht auf die Vorderseite 7 der Darreichungseinheit aus Figur 1. Hierbei ist das Band 22 oder das Teilstück 23 des Bandes 22 in einer Draufsicht zu erkennen. Das Band 22 besteht aus zwei über seine ganze Länge nebeneinander liegenden Streifen einer ersten Komponente 19 und einer zweiten Komponente 18, von welchen die erste Komponente 19 ein ungehärtetes Epoxydharz aufweist, die zweite Komponente 20 wiederum in einem Träger dispergiert ein Mittel zum Härten des Epoxydharzes. Beide Komponenten 19, 20 bilden die knetbare Masse 18 und können für eine gemeinsame Reaktion der reaktiven Inhaltsstoffe miteinander durch Kneten vermischt werden. Das Band 22 ist an der Oberseite durch die Deckfolie 21 abgedeckt. Die Deckfolie 21 erstreckt sich dabei über die gesamte Breite des Bandes 22, also über beide Komponenten 19, 20. FIG. 4 shows a section of a plan view of the front side 7 of the presentation unit FIG. 1 , Here, the band 22 or the portion 23 of the belt 22 can be seen in a plan view. The band 22 consists of two adjacent along its entire length strip of a first component 19 and a second component 18, of which the first component 19 comprises an uncured epoxy resin, the second component 20 in turn dispersed in a carrier, a means for curing the epoxy resin. Both components 19, 20 form the kneadable mass 18 and can be mixed together by kneading for a joint reaction of the reactive ingredients. The band 22 is covered at the top by the cover sheet 21. The cover film 21 extends over the entire width of the belt 22, that is, over both components 19, 20.

Das oberhalb des Bandes 22 angeordnete und sich quer über das Band 22 erstreckende Schneidmesser 10 ist breiter als das Band 22, um einen Eingriff des Schneidmesser 10 in das Band 22 oder die Deckfolie 21 über die gesamte Breite zu und eine sichere Trennungsmöglichkeit eines Teilstückes 23 zu ermöglichen. Zu erkennen ist die Vielzahl an in einer Reihe angeordneten Schneidzähnen 11 des Schneidmessers 10. Die der Deckfolie 21 am nächsten liegenden Bereiche des Schneidmessers 10 bilden dabei die Zahnspitzen 13 der Schneidzähne 11. Das Gegenstück dazu bilden die am weitesten beabstandet liegenden Zahngründe 14. Dabei sind die Schneidzähne 11 derart ausgebildet, dass eine Zahnhöhe 15, also der Abstand zwischen dem Niveau eines Zahngrundes 14 zu einer benachbarten Zahnspitze 13 orthogonal zur Oberfläche des Bandes 22 und/oder der Deckfolie 21 die Stärke der Deckfolie 21 übersteigt, um eine einfache und sichere Abtrennmöglichkeit eines Teilstückes 23 zu ermöglichen. Gleichwohl kann es auch denkbar sein, alle oder einige Schneidzähne 11 aufweisend eine besagte Zahnhöhe 15 bereitzustellen, die zumindest halb so lang ist, wie die Stärke des Bandes 22, um eine Abtrennung des abgewickelten Teilstückes 23 des Bandes 22 zu gewährleisten.The above the belt 22 and arranged transversely across the belt 22 extending cutting blade 10 is wider than the belt 22 to an engagement of the cutting blade 10 in the belt 22 or the cover sheet 21 over the entire width and secure separation possibility to allow a section 23. The plurality of cutting teeth 11 of the cutting blade 10 arranged in a row can be seen. The regions of the cutting blade 10 closest to the cover foil 21 form the tooth tips 13 of the cutting teeth 11. The counterpart to this is formed by the tooth bases 14 furthest apart the cutting teeth 11 are formed such that a tooth height 15, so the distance between the level of a tooth root 14 to an adjacent tooth tip 13 orthogonal to the surface of the belt 22 and / or the cover sheet 21 exceeds the thickness of the cover sheet 21 to a simple and secure Abtrennmöglichkeit to allow a section 23. However, it may also be possible to provide all or some cutting teeth 11 having a said tooth height 15, which is at least half as long as the thickness of the belt 22 to ensure separation of the unwound portion 23 of the belt 22.

In dem gezeigten Ausführungsbeispiel kommen zudem Schneidzähne 11 mit ebenen oder geraden Zahnrücken 12 zum Einsatz. Ein Zahnrücken 12 ist dabei die Erstreckung oder der Verlauf des Schneidzahns 11 von seiner Zahnspitze 13 zu einem benachbarten Zahngrund 14. Gleichwohl kann es sich als zweckmäßig erweisen, zumindest einen Zahnrücken 12 gewölbt auszubilden, um eine Abtrennung des abgewickelten Teilstückes 23 des Bandes zu erleichtern.
