Description

Die Erfindung betrifft eine Vorrichtung zum Spleißen von Bahnen, insbesondere von Papierbahnen für die Herstellung von Wellpappe mit den Merkmalen des Oberbegriffs des Patentanspruchs 1, sowie eine Vorrichtung zur Herstellung von Wellpappe durch Verkleben von wenigstens zwei Bahnen mit einer derartigen Spleißvorrichtung.The invention relates to a device for splicing webs, in particular of paper webs for the production of corrugated board with the features of the preamble of claim 1, and an apparatus for producing corrugated cardboard by gluing at least two webs with such a splicer.

Bei bekannten Spleißvorrichtungen, wie sie beispielsweise in der EP-B-0 453 727 beschrieben sind, ist der eigentlichen Spleißeinrichtung eine Bahnabrolleinrichtung zugeordnet, welche aus einem am Boden befestigbaren Ständer mit zwei seitlichen Tragarmen für jeweils eine Bahnrolle besteht. Von der jeweils aktiven Bahnrolle wird die betreffende Papierbahn abgezogen. Diese durchläuft die außer während des eigentlichen Spleißvorgangs inaktive Spleißeinrichtung und wird der weiteren Verarbeitung zugeführt. Neigt sich die jeweils aktive Bahnrolle dem Ende zu bzw. ist aus anderen Gründen, beispielsweise wegen eines Format- oder Qualitätswechsels, ein Spleißvorgang erforderlich, so wird die Papierbahn der aktiven Bahnrolle in der Spleißeinrichtung abgeschnitten und mit dem vorderen Ende der in der erforderlichen Weise vorbereiteten einzuspleißenden Papierbahn der jeweils anderen Bahnrolle verbunden (verspleißt). Hierzu wird vorzugsweise bereits während des Laufs der zunächst aktiven Bahnrolle das vordere Ende der anzuspleißenden Papierbahn in die Spleißeinrichtung eingeführt, sauber abgeschnitten und mit einem (doppelseitigen) Klebeband versehen. Üblicherweise ist die Spleißeinrichtung so ausgebildet, dass sie einen Bahnspeicher aufweist, der es ermöglicht, eine solche Bahnlänge der zu Ende gehenden aktiven Bahn zu speichern, die erforderlich ist, um die Zeit für das Abschneiden der zunächst aktiven Papierbahn und das Verbinden des hinteren Endes dieser Papierbahn mit dem bereits vorbereiteten vorderen Ende der einzuspleißenden Papierbahn zu überbrücken. Auf diese Weise kann ein kontinuierlicher Betrieb der Anlage zur Weiterverarbeitung der betreffenden Papierbahn gewährleistet werden.In known splicing devices, as described, for example, in EP-B-0 453 727, the actual splicing device is associated with a web unrolling device, which consists of a floor mountable stand with two lateral support arms for each web roll. From the respective active web roll the relevant paper web is deducted. This passes through the inactive during the actual splicing operation splicing device and is sent for further processing. If the respective active web roll is nearing its end or if a splicing operation is required for other reasons, for example due to a change in format or quality, the paper web of the active web roll in the splicer is cut off and prepared with the front end of the required preparation spliced paper web of each other web roll connected (spliced). For this purpose, the front end of the paper web to be spliced is preferably already introduced into the splicing device during the course of the initially active web roll, cut clean and provided with a (double-sided) adhesive tape. Typically, the splicer is configured to include a web storage that allows to store such a web length of the terminating active web required to reduce the time for cutting the initially active paper web and joining the trailing end thereof Paper web to bridge with the already prepared front end of splice paper web. In this way, a continuous operation of the plant for further processing of the relevant paper web can be ensured.

Falls erforderlich, kann dann der Kern, auf welchen die zuvor aktive Papierbahn aufgewickelt war, bzw. der Rest dieser Bahnrolle, von dem jeweiligen seitlichen Tragarm des Bahnabrollers abgenommen und durch eine neue Bahnrolle ersetzt werden, die gegebenenfalls auch eine andere Qualität oder eine andere Breite aufweisen kann.If necessary, then the core on which the previously active paper web was wound, or the remainder of this web roll, can be removed from the respective lateral support arm of the web unreeling and replaced by a new web roll, which may also have a different quality or a different width can have.

Das Abnehmen des Wickelkerns bzw. der verbrauchten Bahnrolle vom jeweiligen Tragarm und das Aufschieben einer neuen Bahnrolle ist ein, in zeitlicher Hinsicht gesehen, relativ aufwendiger Vorgang. Insbesondere bei Wellpappenanlagen, bei denen ein häufiger Format- und/oder Qualitätswechsel erforderlich ist, kann die Verarbeitungszeit, innerhalb der ein konstantes Format bzw. eine konstante Qualität hergestellt wird, kürzer sein als die Zeit für das Entnehmen und Einsetzen einer jeweils erforderlichen neuen Bahnrolle. Dies führt bei bekannten Spleißvorrichtungen zu Stillstandszeiten, die sich nachteilig auf die Produktivität der gesamten Anlage auswirken.The removal of the winding core or the used web roll from the respective support arm and the postponement of a new web roll is a, seen in terms of time, relatively complex operation. Particularly in the case of corrugated board plants, where a frequent format and / or quality change is required, the processing time within which a constant format or a constant quality is produced can be shorter than the time for the removal and insertion of a respectively required new web roll. This leads to down times in known splicing devices, which adversely affect the productivity of the entire system.

Es wurden daher Bahnabroller bzw. Materialbahnzuführeinrichtungen entwickelt, die ein Austauschen einer Bahnrolle in möglichst kurzer Zeit ermöglichen. Eine derartige Vorrichtung ist beispielsweise in der DE-A-39 12 328 beschrieben.Therefore, web dispensers or material web feeders have been developed which allow replacement of a web roll in the shortest possible time. Such a device is described for example in DE-A-39 12 328.

Mit dieser Maßnahme lässt sich jedoch die Zeit für das Ersetzen der Bahnrolle auf dem jeweiligen Tragarm nur bis zu einem gewissen Maß reduzieren. Insbesondere bei Sonderanlagen zur Verarbeitung sehr kleiner Aufträge kann diese Zeit jedoch immer noch zu groß sein, um eine möglichst optimale Produktivität der Gesamtanlage sicherzustellen.With this measure, however, the time for replacing the web roll on the respective support arm can only be reduced to a certain extent. In particular, in special systems for processing very small orders, however, this time may still be too large to ensure the best possible productivity of the entire system.

Aus der GB 2 135 282 A ist eine Spleißvorrichtung für Materialbahnen bekannt, bei der 3 Bahnrollen auf jeweils einer Achse einer insgesamt wiederum rotierbaren Ablaufeinrichtung gehalten sind. Die in der obersten Position befindliche Rolle kann dabei im nächsten Spleißvorgang mit der gerade aktiven Bahn verspleißt werden, wenn sich letztere ihrem Ende zuneigt. Die in der untersten Position befindliche Rolle kann während dessen ausgetauscht und für den übernächsten Spleißvorgang vorbereitet werden.From GB 2 135 282 A, a splicing device for material webs is known, in which three web rolls are held on one axis of a total turn rotatable discharge device. The role in the top position can be spliced in the next splicing with the currently active path, when the latter is coming to an end. The roll located in the lowermost position can be exchanged during this and prepared for the next but one splice process.

Hierfür ist es jedoch erfoderlich, Alle drei Rollen um eine gemeinsame Achse rotierbar zu halten, wodurch ein entsprechender mechanischer Aufwand bedingt ist.For this purpose, however, it is erfoderlich to keep all three rollers rotatable about a common axis, whereby a corresponding mechanical effort is conditional.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, eine konstruktiv einfach gestaltete Vorrichtung zum Spleißen von Bahnen, insbesondere von Papierbahnen für die Herstellung von Wellpappe, zu schaffen, welche auch bei zeitlich sehr kurzen Aufträgen eine optimale Produktivität einer gesamten Anlage, in welche die Spleißvorrichtung integriert ist, gewährleistet. Des Weiteren liegt der Erfindung die Aufgabe zu Grunde, eine Vorrichtung zur Herstellung von Wellpappe durch Verkleben von wenigstens zwei Bahnen zu schaffen, bei der eine derartige Spleißvorrichtung in vorteilhafter Weise integriert ist.Based on this prior art, the invention is based on the object to provide a structurally simple device for splicing webs, in particular of paper webs for the production of corrugated board, which even with very short time orders optimal productivity of an entire system, in which the splicer is integrated, guaranteed. Furthermore, the invention is based on the object to provide a device for producing corrugated cardboard by bonding at least two webs, in which such a splicing device is integrated in an advantageous manner.

Die Erfindung löst diese Aufgabe mit den Merkmalen der Patentansprüche 1 bzw. 7.The invention solves this problem with the features of claims 1 and 7, respectively.

Die Erfindung geht von der Erkenntnis aus, dass die Produktivität einer Anlage zur Verarbeitung von Bahnen, beispielsweise einer Wellpappenanlage, bei welcher in kurzen zeitlichen Abständen Spleißvorgänge erforderlich sind, erheblich gesteigert werden kann, wenn einer üblichen Spleißeinrichtung mit zwei Zuläufen für die zu verspleißenden Bahnen eine Bahnabrolleinrichtung zugeordnet ist, welche zumindest zur Aufnahme von drei Bahnrollen ausgebildet ist. Hierdurch ist es möglich, die jeweils aktive Bahn (d.h. die gerade von der Anlage verarbeitete Bahn) von einer ersten Bahnrolle, die in der Bahnabrolleinrichtung gehalten ist, abzuziehen, und über die Spleißeinrichtung der weiteren Anlage zuzuführen. Das vordere Ende einer zweiten Bahn, die in der Bahnabrolleinrichtung gehalten ist, kann bereits für den nächsten Spleißvorgang vorbereitet und über den jeweils anderen Zulauf der Spleißeinrichtung zugeführt werden, und in dieser bis zur Durchführung des nächsten Spleißvorgangs gehalten sein. In der dritten Position der Bahnabrolleinrichtung kann bereits, falls erforderlich, ein Austausch der betreffenden Bahnrolle erfolgen, so dass theoretisch unmittelbar nach der Durchführung des Spleißvorgangs für die beiden gleichzeitig der Spleißeinrichtung zugeführten Bahnen das vordere Ende dieser dritten Bahn demjenigen Zulauf der Spleißeinrichtung zugeführt werden kann, der nach Durchführung des Spleißvorgangs frei geworden ist (d.h. derjenige Zulauf, über den vor der Durchführung des Spleißvorgangs die jeweils aktive Bahn zugeführt wurde). Die Zeit zwischen zwei Spleißvorgängen kann daher minimal auf die Zeit reduziert werden, die für das Vorbereiten und Einführen des vorderen Endes der zu verspleißenden Bahn erforderlich ist. Sie ist durch die zusätzlich vorhandene Stand-By-Bahnrolle unabhängig von der Zeit für das Auswechseln dieser Bahnrolle.The invention is based on the recognition that the productivity of a system for processing webs, for example a corrugator, in which splice operations are required in short time intervals can be significantly increased if a conventional splicer with two inlets for the webs to be spliced Rail derroller is associated, which is formed at least for receiving three web rolls. This makes it possible to deduct the respective active web (ie, the web currently being processed by the system) from a first web roll held in the web unrolling device and to feed it to the further device via the splicing device. The front end of a second web, which is held in the web unrolling device, can already be prepared for the next splicing operation and fed via the other inlet of the splicing device, and held therein until the next splicing operation. In the third position of the Bahnabrolleinrichtung can, if necessary, carried out an exchange of the respective web roll, so that theoretically immediately after performing the splicing operation for the two simultaneously supplied to the splicing device tracks the front end of this third track that inlet of the splicer can be fed, which has become free after performing the splicing operation (ie, that feed over which the respective active web was supplied prior to performing the splicing operation). The time between two splices can therefore be reduced minimally to the time required for the preparation and insertion of the leading end of the web to be spliced. It is independent of the time for the replacement of this web roll by the additionally existing stand-by web roll.

Nach der Erfindung erfolgt das Zuführen der Bahnen zur Spleißeinrichtung so, dass die Bahnen zweier Bahnrollen in zwei bestimmten Aufnahmepositionen der Bahnabrolleinrichtung abwechselnd nur einem einzigen der beiden Zuläufe der Spleißeinrichtung zuführbar sind. Hierdurch vereinfacht sich der Aufbau der Bahnabrolleinrichtung. Insbesondere sind, wenn überhaupt, nur eine minimale Anzahl von Umlenkrollen für das Zuführen der Bahnen zu den Zuläufen der Spleißeinrichtung erforderlich. Insbesondere ist es möglich, übliche Bahnabrolleinrichtungen zu verwenden, die lediglich zwei Bahnrollen aufnehmen können. Im Gegensatz zu bekannten Spleißvorrichtungen wird jedoch eine solche übliche Bahnabrolleinrichtung lediglich einem einzigen Zulauf der eigentlichen Spleißeinrichtung zugeordnet.According to the invention, the feeding of the webs to the splicing device takes place in such a way that the webs of two web rolls can be fed alternately only to one of the two inlets of the splicing device in two specific receiving positions of the web unwinding device. This simplifies the construction of the web-rolling device. In particular, only a minimal number of pulleys are required, if any, for feeding the webs to the inlets of the splicer. In particular, it is possible to use conventional Bahnabrolleinrichtungen that can accommodate only two web rolls. In contrast to known splicing devices, however, such a conventional web unrolling device is assigned to only a single feed of the actual splicing device.

Eine weitere Möglichkeit besteht darin, eine übliche Spleißvorrichtung mit einer üblichen Bahnabrolleinrichtung mit zwei Aufnahmepositionen zu verwenden, wobei jede Position der üblichen Bahnabrolleinrichtung jeweils einem Zulauf der Spleißeinrichtung zugeführt ist, und einem oder beiden der Zuläufe der Spleißeinrichtung eine weitere Abrolleinheit zur Aufnahme einer weiteren Bahnrolle zuzuordnen ist.Another possibility is to use a conventional splicer with a conventional Bahnabrolleinrichtung with two receiving positions, each position of the conventional Bahnabrolleinrichtung is fed to each one inlet of the splicer, and assign one or both of the feeds of the splicing another Abrolleinheit for receiving a further web roll is.

Wie bereits erwähnt, ist es selbstverständlich möglich, jedem oder nur einem einzigen der beiden Zuläufe zwei Aufnahmepositionen für Bahnrollen der gesamten Bahnabrolleinrichtung zuzuordnen. Erfolgt dies lediglich für einen der beiden Zuläufe, so ist lediglich auf einer der beiden Seiten der Spleißeinrichtung ein "schneller Spleißvorgang" möglich.As already mentioned, it is of course possible to associate each or only one of the two feeds with two receiving positions for web rolls of the entire web unrolling device. If this occurs only for one of the two feeds, then a "fast splicing process" is possible only on one of the two sides of the splicing device.

Eine Vorrichtung zur Herstellung von Wellpappe durch Verkleben von wenigstens zwei Bahnen kann so ausgebildet sein, dass jeder der beiden zu verklebenden Bahnen eine Spleißeinrichtung der vorstehend erläuterten Art zugeordnet ist.A device for producing corrugated cardboard by adhering at least two webs may be formed so that each of the two webs to be bonded is assigned a splicing device of the type described above.

Die Vorrichtung zur Herstellung von Wellpappe kann beispielsweise so ausgebildet sein, dass übliche Spleißvorrichtungen mit jeweils einer Bahnabrolleinrichtung für zwei Bahnrollen verwendet werden, wobei zwischen den Spleißeinrichtungen, die vorzugsweise horizontal nebeneinander angeordnet werden, eine weitere übliche Bahnabrolleinrichtung mit zwei Aufnahmepositionen für zwei Bahnrollen vorgesehen ist. Jede der beiden Aufnahmepositionen kann dann der jeweils benachbarten Spleißeinrichtung oder dem benachbarten Zulauf der jeweiligen Spleißeinrichtung zugeordnet werden.The apparatus for producing corrugated cardboard may, for example, be designed such that conventional splicing devices are used, each with a web-rolling device for two web rolls, wherein between the splicing devices, which are preferably arranged horizontally next to one another, another conventional web-rolling device is provided with two receiving positions for two web rolls. Each of the two receiving positions can then be assigned to the respectively adjacent splicing device or the adjacent inlet of the respective splicing device.

Weitere Ausführungsformen der Erfindung ergeben sich aus den Unteransprüchen.Further embodiments of the invention will become apparent from the dependent claims.

The invention will be explained in more detail with reference to embodiments illustrated in the drawings. In the drawing show:

Fig. 2
a larger section of the corrugator in Fig. 1 with two splicing devices according to the invention and

another embodiment of a corrugator with two splicing devices according to the invention.

Die in Fig. 1 ausschnittsweise dargestellte Wellpappenanlage 1 ermöglicht die Herstellung einer doppelseitigen Wellpappe, bei der zwei einseitige Wellpappen 3 und eine Deckbahn 5 miteinander verklebt werden. Die beiden einseitigen Wellpappebahnen werden dem in Fig. 1 dargestellten Ausschnitt der gesamten Wellpappenanlage in der aus der Figur ersichtlichen Pfeilrichtung (von rechts nach links) zugeführt.The corrugated cardboard plant 1 shown in detail in FIG. 1 enables the production of a double-sided corrugated cardboard, in which two single-sided corrugated cardboard 3 and a cover sheet 5 are glued together. The two single-sided corrugated board webs are fed to the section of the entire corrugator system shown in FIG. 1 in the direction of the arrow (from right to left) shown in the FIGURE.

Die in Fig. 1. dargestellte Spleißvorrichtung 7 dient für das Verspleißen von Bahnen für die Deckbahn 5. Die Spleißvorrichtung 7 besteht im Wesentlichen aus der eigentlichen Spleißeinrichtung 9, welche zwei Zuläufe 11 für die beiden jeweils zu verspleißenden Bahnen aufweist. Die Spleißvorrichtung 7 umfasst des Weiteren eine Bahnabrolleinrichtung 13, die eine übliche Bahnabrolleinheit 15 umfasst, welche unterhalb der Spleißeinrichtung 9 angeordnet ist. Die Spleißeinrichtung 9 und die übliche Bahnabrolleinheit 15 bilden somit eine übliche, an sich bekannte Spleißvorrichtung mit zwei Aufnahmepositionen für Bahnrollen.The splicing device 7 shown in FIG. 1 is used for splicing webs for the cover web 5. The splicing device 7 consists essentially of the actual splicing device 9, which has two inlets 11 for the two webs to be spliced in each case. The splicing apparatus 7 further comprises a web unrolling device 13 which comprises a conventional web unrolling unit 15, which is arranged below the splicing device 9. The splicing device 9 and the usual web-rolling unit 15 thus form a conventional, known per se splicing device with two receiving positions for web rolls.

Die Bahnabrolleinrichtung 13 umfasst des Weiteren zwei Bahnabrolleinheiten 17, die jeweils zur Aufnahme einer einzige Bahnrolle dienen. Bei der in Fig. 1 dargestellten Ausführungsform sind die weiteren Bahnabrolleinheiten 17 jeweils links und rechts neben der üblichen Spleißvorrichtung angeordnet. Auf diese Weise ergibt sich der Vorteil, dass bereits existierende Wellpappenanlagen mit üblichen Spleißvorrichtungen mit jeweils einer Bahnabrolleinrichtung für zwei Bahnrollen zu einer Spleißvorrichtung nach der vorliegenden Erfindung nachgerüstet werden können. Hierzu müssen lediglich zwei weitere Bahnabrolleinheiten 17 vorgesehen werden.The web roll-off device 13 further comprises two web roll-off units 17, each for receiving a single web roll. In the embodiment shown in Fig. 1, the further Bahnabrolleinheiten 17 are each arranged to the left and right of the usual splicer. In this way, there is the advantage that already existing corrugator systems with conventional splicing devices each equipped with a web-rolling device for two web rolls to a splicing device according to the present invention can be. For this purpose, only two further Bahnabrolleinheiten 17 must be provided.

Wie aus Fig. 1 ersichtlich, kann das Zuführen der Bahnen 5 von den Bahnrollen 21 unter Zuhilfenahme jeweils einer Umlenkeinheit 23 erfolgen. Die Umlenkeinheiten 23 weisen entsprechend angeordnete Umlenkrollen auf, um die jeweilige Bahn 5 von den in den Bahnabrolleinheiten 17 gehaltenen Bahnrollen 21 unter einem Bedienpodest hindurch dem jeweiligen Zulauf 11 der Spleißeinrichtung 9 zuzuführen.As can be seen from FIG. 1, the feeding of the webs 5 from the web rolls 21 can take place with the aid of a deflection unit 23 in each case. The deflecting units 23 have correspondingly arranged deflecting rollers in order to feed the respective web 5 from the web rolls 21 held in the web unrolling units 17 under a control platform through the respective inlet 11 of the splicing device 9.

Wie in Fig. 1 dargestellt, dienen die Bedienpodeste der Umlenkeinheiten 23 als Standfläche für eine Bedienperson, die auf diese Weise die Anlage bequem bedienen und das jeweils vordere Ende der Bahn 5 von den Bahnrollen 21 der Bahnabrolleinheiten 17 dem jeweilige Zulauf 11 der Spleißeinrichtung 9 zuführen kann.As shown in Fig. 1, serve the operating platforms of the deflection units 23 as a standing area for an operator who operate the system conveniently in this way and each lead the front end of the web 5 of the web rolls 21 of Bahnabrolleinheiten 17 the respective inlet 11 of the splicing device 9 can.

Bei der in Fig. 1 dargestellten Betriebsphase wird die von der in Fig. 1 rechts dargestellten, in der betreffenden Bahnabrolleinheit 17 gehaltenen Bahnrolle 21 abgezogene Bahn der weiteren Anlage zur Verarbeitung über die Spleißvorrichtung 7 zugeführt. Diese Bahn wird daher als aktive Bahn 5akt bezeichnet. Dem jeweils anderen (linken) Zulauf 11 der Spleißeinrichtung 9 führt die Bedienperson gerade die von der in der linken Position der Bahnabrolleinheit gehaltenen Bahnrolle 21 abgezogene Bahn 5 zu. Diese Bahn wird im nächsten Spleißvorgang mit der gerade aktiven Bahn 5akt verspleißt. Daher wird diese Bahn auch als zu verspleißende Bahn 5spl bezeichnet.In the operating phase shown in FIG. 1, the web drawn off from the web roll 21 shown on the right in FIG. 1 and held in the relevant web roll-off unit 17 is fed to the further system for processing via the splicing device 7. This web is therefore referred to as active web 5 act . The respective other (left) inlet 11 of the splicing device 9, the operator just leads to the deducted from the held in the left position of the Bahnabrolleinheit web roll 21 web 5 to. This web is spliced in the next splicing operation with the currently active web 5 akt . Therefore, this web is also referred to as splice web 5 spl .

Die beiden übrigen Bahnrollen 21, die in der linken Bahnabrolleinheit 17 bzw. im rechten Arm der Abrolleinheit 15 gehalten sind, werden im Folgenden als Stand-By-Bahnrollen 21 bezeichnet. Bei der in Fig. 1 dargestellten Betriebsphase wurde die im rechten Arm der Bahnabrolleinheit 15 gehaltene Bahnrolle 21 bereits durch eine neue Bahnrolle ersetzt. Nachdem die Bedienperson die Bahn 5spl für den nächsten Spleißvorgang vorbereitet hat, kann diese die in der linken Bahnabrolleinheit 17 gehaltene, fast leere Bahnrolle 21 durch eine neue Bahnrolle 21 austauschen. Selbstverständlich kann dies mittels einer geeigneten Vorrichtung auch vollständig automatisch erfolgen.The two remaining web rolls 21, which are held in the left web roll-off unit 17 or in the right arm of the unwinding unit 15, are referred to below as Stand-by web rolls 21. In the operating phase shown in FIG. 1, the web roll 21 held in the right arm of the web roll-off unit 15 has already been replaced by a new web roll. After the operator has prepared the web 5 spl for the next splicing operation, it can exchange the almost empty web roll 21 held in the left web unrolling unit 17 by a new web roll 21. Of course, this can also be done completely automatically by means of a suitable device.

Damit ist bei der in Fig. 1 dargestellten Ausführungsform einer Spleißvorrichtung auf beiden Seiten der Spleißvorrichtung 7, d.h. für jeden Zulauf 11 der Spleißeinrichtung 9 ein Zuführen einer zu verspleißenden Bahn 5 möglich, während die in der jeweiligen Stand-By-Position gehaltene Bahnrolle ausgetauscht oder die betreffende Bahnrolle in dieser Position zur weiteren Benutzung für den nächsten Spleißvorgang als Vorrat gehalten werden kann.Thus, in the embodiment shown in Fig. 1, a splicer is provided on both sides of the splicer 7, i. for each inlet 11 of the splicing device 9, feeding of a web 5 to be spliced is possible, while the web roll held in the respective stand-by position can be exchanged or the web roll in question can be held in this position for further use for the next splicing operation.

Der in Fig. 2 dargestellte größere Ausschnitt der Wellpappenanlage 1 zeigt zwei im Wesentlichen identische Spleißvorrichtungen 7, wobei die in Fig. 2 zusätzlich gezeigte Spleißvorrichtung 7' nur auf ihrer rechten Seite über eine weitere Bahnabrolleinheit 17 verfügt, deren Aufnahmeposition für eine Bahnrolle dem rechten Zulauf 11 der Spleißeinrichtung 9 zugeordnet ist. Die Spleißvorrichtung 7' dient für das Spleißen und Zuführen einer Teilbahn 3a zu einer einseitigen Wellpappenmaschine 25, mittels welcher die Teilbahn 3a und eine weitere, in Fig. 2 von rechts zugeführte Teilbahn 3b zu einer einseitigen Wellpappe 3 verarbeitet wird.The illustrated in Fig. 2 larger section of the corrugator 1 shows two substantially identical splicing devices 7, wherein the splice device additionally shown in Fig. 2 7 'only on its right side on a further Bahnabrolleinheit 17, whose receiving position for a web roll the right inlet 11 of the splicing device 9 is assigned. The splicing device 7 'is used for splicing and feeding a partial web 3a to a single-sided corrugated cardboard machine 25, by means of which the partial web 3a and a further, in Fig. 2 supplied from the right sub-web 3b is processed to a one-sided corrugated board 3.

In Folge der lediglich einen weiteren, der Spleißeinrichtung 9 zugeordneten weiteren Bahnabrolleinheit 17 ist bei der Spleißvorrichtung 7 nur jeder zweite Spleißvorgang "schnell durchführbar", nämlich diejenigen Spleißvorgänge, bei denen die zu verspleißende Bahn 5spl von einer Bahnrolle 21 abgezogen wird, die sich in der rechten Position der Bahnabrolleinheit 15 oder in der Position der weiteren Bahnabrolleinheit 17 befindet.As a result of only one other, the splicing device 9 associated further Bahnabrolleinheit 17 is in the splicing device 7, only every second splicing process "quickly feasible", namely those splicing operations in which the splice web 5 spl is deducted from a web roll 21, the is in the right position of the web roll-off unit 15 or in the position of the other web roll-off unit 17.

Da jedoch bei der von außen sichtbaren Deckbahn 5 häufiger Qualitätswechsel gewünscht werden (und damit häufiger Spleißvorgänge erforderlich werden) als bei den übrigen Bahnen der doppelseitigen Wellpappe, ist die vereinfachte Ausführungsform der Spleißvorrichtung 7' in Fig. 2 durchaus zulässig, ohne die gesamte Produktivität der Wellpappenanlage 1 wesentlich nachteilig zu beeinflussen.However, since in the cover sheet visible from the outside 5 frequent quality changes are desired (and thus more frequent splicing operations are required) than in the other webs of double-sided corrugated board, the simplified embodiment of the splicing device 7 'in Fig. 2 is quite permissible without the overall productivity of Corrugated cardboard plant 1 to affect significantly adversely.

Die in Fig. 3 dargestellte Ausführungsform einer Wellpappenanlage 1 unterscheidet sich von der Ausführungsform in den Fig. 1 und 2 lediglich dadurch, dass der zweiten Spleißvorrichtung 7', ebenso wie der Spleißvorrichtung 7, zwei weitere Positionen für Bahnrollen 21 zugeordnet sind. Gegenüber der in Fig. 2 dargestellten Ausführungsform wurde hierzu lediglich die in Fig. 1 rechts dargestellte weitere Bahnabrolleinheit 17 durch eine übliche Bahnabrolleinheit 15 mit zwei seitlichen Tragarmen ersetzt. Somit ergeben sich auch bei der Spleißvorrichtung 7 zwei "schnelle Seiten".The embodiment of a corrugator 1 shown in FIG. 3 differs from the embodiment in FIGS. 1 and 2 only in that the second splicer 7 ', as well as the splicer 7, are assigned two further positions for web rolls 21. Compared with the embodiment shown in FIG. 2, only the further web-rolling unit 17 shown on the right in FIG. 1 has been replaced by a conventional web-rolling unit 15 with two lateral support arms. Thus, the splicing device 7 also has two "fast sides".
