Ein derartiges erstes Leimdamm-Dichtungselement ist insbesondere imstande, selbstständig um die Schwenkachse zu schwenken, was stets eine automatische Anpassung an die Walze erlaubt und so zu einer besonders hohen Dichtwirkung und einfachen Handhabung führt. Dies ist insbesondere bei Verstellung der jeweiligen Walze vorteilhaft.The constraining element and the associated glue dam sealing element can preferably be pivoted relative to one another at least over a pivoting range, in particular freely or unhindered. Such a first glue dam sealing element is in particular able to pivot independently about the pivot axis, which always allows automatic adaptation to the roller and thus leads to a particularly high sealing effect and simple handling. This is particularly advantageous when adjusting the respective roller.

Eine jeweilige Schwenkeinrichtung ist vorzugsweise imstande, das Zwängelement zu verschwenken.A respective pivoting device is preferably able to pivot the constraining element.

Es ist von Vorteil, wenn dann zwischen drei und sechs Zwängfederelemente vorhanden sind.According to a preferred embodiment, a plurality of compression spring elements are present. These then advantageously engage in a circumferential direction of the constraining element on the constraining element at a distance from one another. It is advantageous if there are between three and six compression spring elements.

Das Zwängfederelement übt auf das Zwängelement ein Schwenkmoment aus, was letztendlich eine resultierende Zwängkraft auf das jeweilige Leimdamm-Dichtungselement hervorruft.The constraining spring element exerts a pivoting moment on the constraining element, which ultimately causes a resulting constraining force on the respective glue dam sealing element.

Das Zwängelement ist gemäß einer bevorzugten Ausführungsform exzentrisch an der Trageinrichtung gelagert.According to a preferred embodiment, the constraining element is mounted eccentrically on the support device.

Gemäß einer bevorzugten Ausführungsform ist das Zwängelement hebelartig.

Ein Schwenkmotor einer alternativen Schwenkeinrichtung ist günstigerweise pneumatischer, hydraulischer und/oder elektrischer Art.A swivel motor of an alternative swivel device is advantageously of a pneumatic, hydraulic and / or electrical type.

Eine Wellpappe-Anlage, wie sie in Fig. 1 in ihrer Gesamtheit schematisch dargestellt ist, umfasst eine Wellpappe-Herstellvorrichtung 1 zur Herstellung einer einseitig kaschierten, endlosen Wellpappe-Bahn 2.A corrugated cardboard machine like the one in Fig. 1 Shown schematically in its entirety, comprises a corrugated cardboard manufacturing device 1 for producing an endless corrugated cardboard web 2 laminated on one side.

Von einer ersten Abrolleinrichtung 3 wird eine, vorzugsweise endlose, erste Materialbahn 4 der Wellpappe-Herstellvorrichtung 1 über eine Vorheizeinrichtung 5 zugeführt. Die erste Materialbahn 4 stellt eine Deckbahn für die in der Wellpappe-Herstellvorrichtung 1 hergestellte, einseitig kaschierte Wellpappe-Bahn 2 dar.A, preferably endless, first material web 4 is fed to the corrugated cardboard manufacturing device 1 from a first unrolling device 3 via a preheating device 5. The first material web 4 represents a cover web for the corrugated cardboard web 2 laminated on one side in the corrugated cardboard manufacturing device 1.

Die erste Materialbahn 4 wird in der Wellpappe-Herstellvorrichtung 1 mit einer, vorzugsweise endlosen, zweiten Materialbahn 6 zusammengeführt, die von einer zweiten Abrolleinrichtung 7 abgerollt wird.The first material web 4 is brought together in the corrugated cardboard manufacturing device 1 with a, preferably endless, second material web 6, which is unrolled by a second unrolling device 7.

Die zweite Materialbahn 6 wird in der Wellpappe-Herstellvorrichtung 1 zur Erzeugung einer Wellung durch ein Riffelwalzenpaar hindurchgeführt, das eine untere bzw. erste Riffelwalze 8 und eine obere bzw. zweite Riffelwalze 9 umfasst. Die zweite Materialbahn 6 liegt nach dieser Durchführung durch das Riffelwalzenpaar als Wellbahn 10 vor. Die Wellbahn 10 weist abwechselnd Wellenspitzen und Wellentäler auf.The second material web 6 is guided in the corrugated cardboard manufacturing device 1 to produce a corrugation through a pair of corrugating rollers, the lower or first corrugating roller 8 and an upper or second corrugating roller 9 includes. The second material web 6 is present as a corrugated web 10 after this implementation by the pair of corrugating rollers. The corrugated sheet 10 alternately has wave peaks and wave troughs.

Anschließend werden die Wellenspitzen der Wellbahn 10 in einer Leimauftrags-Einrichtung 11 der Wellpappe-Herstellvorrichtung 1 beleimt. Die Leimauftrags-Einrichtung 11 ist in einer Transportrichtung 12 der zweiten Materialbahn 6 stromabwärts zu einem durch die Riffelwalzen 8, 9 ausgebildeten Riffelspalt angeordnet.The corrugated tips of the corrugated web 10 are then glued in a glue application device 11 of the corrugated cardboard manufacturing device 1. The glue application device 11 is arranged in a transport direction 12 of the second material web 6 downstream to a corrugation gap formed by the corrugating rollers 8, 9.

Wie Fig. 2 zeigt, umfasst die Leimauftrags-Einrichtung 11 einen Leimbehälter 13 und eine Leimdosierwalze 14 sowie eine Leimauftragswalze 15. Die Leimauftragswalze 15 ist zwischen der Leimdosierwalze 14 und der zweiten Riffelwalze 9 angeordnet.How Fig. 2 shows, the glue application device 11 comprises a glue container 13 and a glue metering roller 14 and a glue application roller 15. The glue application roller 15 is arranged between the glue metering roller 14 and the second corrugated roller 9.

Die Leimdosierwalze 14 und die Leimauftragswalze 15 sind in Seitenwänden des Leimbehälters 13 gelagert. Die Leimdosierwalze 14 ist um eine erste Drehachse 16 drehbar bzw. drehantreibbar gelagert, während die Leimauftragswalze 15 um eine zweite Drehachse 17 drehbar bzw. drehantreibbar gelagert ist. Die Drehachsen 16, 17 verlaufen parallel zueinander und auch parallel zu Riffelwalzen-Drehachsen der Riffelwalzen 8, 9.The glue metering roller 14 and the glue application roller 15 are mounted in the side walls of the glue container 13. The glue metering roller 14 is rotatably or rotationally driven about a first axis of rotation 16, while the glue application roller 15 is rotatably or rotationally driven about a second axis of rotation 17. The axes of rotation 16, 17 run parallel to one another and also parallel to the corrugation roller axes of rotation of the corrugation rollers 8, 9.

Zum Durchführen und Beleimen der Wellbahn 10 bildet die Leimauftragswalze 15 mit der zweiten Riffelwalze 9 einen Walzenspalt bzw. Leimspalt 18 aus. Sich in dem Leimbehälter 13 befindender Leim wird über die in diesen eingetauchte, um die zweite Drehachse 17 rotierende Leimauftragswalze 15 auf die freien Wellenspitzen der transportierten, dort an der zweiten Riffelwalze 9 anliegenden Wellbahn 10 aufgetragen.To carry out and glue the corrugated web 10, the glue application roller 15 forms a roller gap or glue gap 18 with the second corrugated roller 9. Glue located in the glue container 13 is applied to the free shaft tips of the transported corrugated web 10 resting there on the second corrugating roller 9 via the glue application roller 15 immersed in the glue container and rotating about the second axis of rotation 17.

Die Leimdosierwalze 14 ist im Wesentlichen gegenüberliegend zu der zweiten Riffelwalze 9 benachbart zu der Leimauftragswalze 15 angeordnet und dient zum Ausbilden einer gleichmäßigen Leimschicht auf der Leimauftragswalze 15. Die Leimdosierwalze 14 bildet günstigerweise eine Leimabquetschwalze und liegt dafür an der Leimauftragswalze 15 umfangsseitig an. Sie rotiert im Einsatz um ihre erste Drehachse 16 und ist vorzugsweise in den Leim eingetaucht.The glue metering roller 14 is arranged essentially opposite the second corrugating roller 9 adjacent to the glue application roller 15 and serves to form a uniform layer of glue on the glue application roller 15. The glue metering roller 14 advantageously forms a glue squeezing roller and for this lies against the glue application roller 15 on the circumference. In use, it rotates about its first axis of rotation 16 and is preferably immersed in the glue.

Die Leimdosierwalze 14 und die Leimauftragswalze 15 sind durch mindestens einen Antrieb (nicht dargestellt) im Betrieb rotierend angetrieben.The glue metering roller 14 and the glue application roller 15 are driven in rotation by at least one drive (not shown).

Wie Fig. 3 bis 5 zeigen, hat die Leimauftrags-Einrichtung 11 ferner zwei Leimdamm-Dichtungsanordnungen 19, die zum Begrenzen des Leims in dem Leimbehälter 13 und Einstellen eines Beleimungsbereichs der Wellbahn 10 dienen. Hierauf wird nachfolgend noch näher eingegangen.How 3 to 5 show, the glue application device 11 also has two glue dam sealing arrangements 19 which serve to limit the glue in the glue container 13 and to set a gluing area of the corrugated web 10. This will be discussed in more detail below.

Die mit Leim versehene Wellbahn 10 wird anschließend in der Wellpappe-Herstellvorrichtung 1 mit der transportierten ersten Materialbahn 4 zusammengeführt, um die einseitig kaschierte Wellpappe-Bahn 2 zu erhalten. Zum Andrücken der ersten Materialbahn 4 gegen die mit Leim versehene Wellbahn 10, die dort bereichsweise an der zweiten Riffelwalze 9 anliegt, hat die Wellpappe-Herstellvorrichtung 1 eine Andrückeinrichtung 20. Gemäß Fig. 1 ist die Andrückeinrichtung 20 als Andrückwalze ausgeführt, während sie gemäß Fig. 2 als Andrück-Bandmodul mit zwei Andrückwalzen 21 und einem um diese herumgeführten Andrückband 22 ausgebildet ist. Die Andrückeinrichtung 20 ist bezogen auf die Wellbahn 10 stromabwärts zu dem Walzenspalt 18 angeordnet.The corrugated web 10 provided with glue is then brought together in the corrugated cardboard manufacturing device 1 with the transported first material web 4 in order to obtain the corrugated cardboard web 2 laminated on one side. In order to press the first material web 4 against the corrugated web 10 provided with glue, which in some areas bears against the second corrugating roller 9, the corrugated cardboard manufacturing device 1 has a pressing device 20. According to FIG Fig. 1 is the pressure device 20 designed as a pressure roller, while according to Fig. 2 is designed as a pressure belt module with two pressure rollers 21 and a pressure belt 22 guided around them. The pressing device 20 is arranged downstream of the nip 18 with respect to the corrugated web 10.

Aus der Wellpappe-Herstellvorrichtung 1 wird dann die aus der ersten Materialbahn 4 und zweiten Materialbahn 6/Wellbahn 10 gebildete, einseitig kaschierte Wellpappe-Bahn 2 herausgeführt und um eine Umlenkwalze 23 zu einer Vorheizanordnung 24 der Wellpappe-Anlage geführt.The corrugated cardboard web 2, which is formed from the first material web 4 and the second material web 6 / corrugated web 10 and is laminated on one side, is then led out of the corrugated cardboard production device 1 and is guided around a deflection roller 23 to a preheating arrangement 24 of the corrugated cardboard system.

Die Wellpappe-Anlage hat außerdem eine dritte Abrolleinrichtung 25 für eine, vorzugsweise endlose, dritte Materialbahn 26. Die dritte Materialbahn 26 bildet eine Kaschierbahn für die einseitig kaschierte Wellpappe-Bahn 2. Sie wird ebenfalls der Vorheizanordnung 24 zugeführt.The corrugated cardboard system also has a third unrolling device 25 for a preferably endless, third material web 26. The third material web 26 forms a laminating web for the corrugated cardboard web 2 laminated on one side. It is also fed to the preheating arrangement 24.

In der Vorheizanordnung 24 werden die einseitig kaschierte Wellpappe-Bahn 2 und die dritte Materialbahn 26 erwärmt. Die Vorheizanordnung 24 weist dazu zwei beheizbare Heizwalzen 27 auf, die von der einseitig kaschierten Wellpappe-Bahn 2 und der dritten Materialbahn 26 berührt werden.In the preheating arrangement 24, the one-sided laminated corrugated web 2 and the third material web 26 are heated. For this purpose, the preheating arrangement 24 has two heatable heating rollers 27 which are in contact with the one-sided laminated corrugated web 2 and the third material web 26.

Ferner umfasst die Wellpappe-Anlage ein Leimwerk 28, das stromabwärts zu der Vorheizanordnung 24 angeordnet ist und eine weitere Leimauftrags-Einrichtung bildet. Das Leimwerk 28 hat eine Beleimungswalze bzw. Leimauftragswalze 29, die teilweise in ein Leimbad 30 eintaucht. Die einseitig kaschierte Wellpappe-Bahn 2 befindet sich mit ihrer Wellbahn 10 mit der Beleimungswalze 29 in Kontakt, sodass Leim aus dem Leimbad 30 auf die Wellenspitzen der Wellbahn 10 übertragen wird.Furthermore, the corrugated cardboard system comprises a glue unit 28, which is arranged downstream of the preheating arrangement 24 and forms a further glue application device. The glue unit 28 has a gluing roller or glue application roller 29 which is partially immersed in a glue bath 30. The corrugated cardboard web 2 laminated on one side is in contact with the gluing roller 29 with its corrugated web 10, so that glue is transferred from the glue bath 30 to the corrugated tips of the corrugated web 10.

Ferner umfasst das Leimwerk 28 gemäß einer bevorzugten Ausführungsform eine Leimabquetschwalze bzw. Leimdosierwalze (nicht dargestellt), die der Beleimungswalze 29 zugeordnet ist und parallel zu dieser verläuft. Vorzugsweise hat das Leimwerk 28 zwei entsprechende Leimdamm-Dichtungsanordnungen 19 (nicht dargestellt).Furthermore, according to a preferred embodiment, the gluing unit 28 comprises a glue squeeze roller or glue metering roller (not shown) which is assigned to the gluing roller 29 and runs parallel to it. The glue unit 28 preferably has two corresponding glue dam sealing arrangements 19 (not shown).

Die Leimdamm-Dichtungsanordnungen 19 können bei dem Leimwerk 28 und/oder bei der Leimauftrags-Einrichtung 11 der Wellpappe-Herstellvorrichtung 1 vorhanden sein.The glue dam sealing arrangements 19 can be present in the gluing unit 28 and / or in the glue application device 11 of the corrugated cardboard manufacturing device 1.

Die Wellpappe-Anlage weist außerdem eine Heiz-Andrückeinrichtung 31 auf, die stromabwärts zu dem Leimwerk 28 angeordnet ist. Die Heiz-Andrückeinrichtung 31 umfasst einen horizontalen, mit Heizelementen (nicht dargestellt) versehenen Tisch 32 und einen um Walzen 33 geführten, endlosen Andrückgurt 34. Zwischen dem Andrückgurt 34 und dem Tisch 32 ist ein Andrückspalt gebildet, durch den die einseitig kaschierte Wellpappe-Bahn 2 und die dritte Materialbahn 26 transportiert und dort aneinander gedrückt werden. In der Heiz-Andrückeinrichtung 31 wird eine dreilagige, endlose Wellpappe-Bahn 35 gebildet.The corrugated cardboard system also has a heating pressure device 31 which is arranged downstream of the gluing unit 28. The heating pressure device 31 comprises a horizontal table 32 provided with heating elements (not shown) and an endless pressure belt 34 guided around rollers 33. A pressure gap is formed between the pressure belt 34 and the table 32, through which the corrugated cardboard web laminated on one side is formed 2 and the third material web 26 are transported and pressed together there. A three-layer, endless corrugated cardboard web 35 is formed in the heating pressure device 31.

Stromabwärts zu der Heiz-Andrückeinrichtung 31 ist eine Kurz-Querschneidevorrichtung 36 der Wellpappe-Anlage angeordnet. Die dreilagige Wellpappe-Bahn 35 wird durch die Kurz-Querschneidevorrichtung 36 hindurchgeführt. Die Kurz-Querschneidevorrichtung 36 dient einerseits zum sicheren Entfernen von Anfahrabfall aus der dreilagigen Wellpappe-Bahn 35 und andererseits zur Durchführung von Auftrags- bzw. Formatwechseln an der dreilagigen Wellpappe-Bahn 35.A short cross-cutting device 36 of the corrugated cardboard system is arranged downstream of the heating pressure device 31. The three-layer corrugated cardboard web 35 is passed through the short cross-cutting device 36. The short cross-cutting device 36 serves on the one hand for the safe removal of start-up waste from the three-layer corrugated cardboard web 35 and on the other hand for carrying out job or format changes on the three-layer corrugated cardboard web 35.

Stromabwärts zu der Kurz-Querschneidevorrichtung 36 hat die Wellpappe-Anlage eine Längs-Schneide-Rillvorrichtung 37 mit zwei Rillstationen 38 und zwei hintereinander angeordneten Längs-Schneidestationen 39. Die dreilagige Wellpappe-Bahn 35 wird durch die Längs-Schneide-Rillvorrichtung 37 hindurchgeführt. Durch die Rillstationen 38 ist die dreilagige Wellpappe-Bahn 35 rillbar, während die dreilagige Wellpappe-Bahn 35 durch die Längs-Schneidestationen 39 in mehrere endlose Teil-Wellpappe-Bahnen 40, 41 teilbar ist. Die Teil-Wellpappe-Bahnen 40, 41 werden anfangs noch parallel nebeneinander gefördert.Downstream of the short cross-cutting device 36, the corrugated cardboard system has a longitudinal-cutting-creasing device 37 with two creasing stations 38 and two longitudinal-cutting stations 39 arranged one behind the other. The three-layer corrugated cardboard web 35 is separated by the longitudinal-cutting-creasing device 37 passed through. The three-layer corrugated cardboard web 35 can be creased by the creasing stations 38, while the three-layer corrugated cardboard web 35 can be divided into a plurality of endless partial corrugated cardboard webs 40, 41 by the longitudinal cutting stations 39. The partial corrugated cardboard webs 40, 41 are initially conveyed side by side in parallel.

Stromabwärts zu der Längs-Schneide-Rillvorrichtung 37 hat die Wellpappe-Anlage eine Weiche 42, die zum Transportieren der Teil-Wellpappe-Bahnen 40, 41 in unterschiedliche Ebenen dient.Downstream of the longitudinal cutting-creasing device 37, the corrugated cardboard system has a switch 42 which serves to transport the partial corrugated cardboard webs 40, 41 into different planes.

Stromabwärts zu der Weiche 42 hat die Wellpappe-Anlage eine QuerSchneidevorrichtung 43 mit zwei übereinander angeordneten Teil-Querschneide-Einrichtungen 44, 45. Jede Teil-Querschneide-Einrichtung 44, 45 hat zwei paarweise übereinander angeordnete Querschneide-Walzen 46, 47. Die obere Teil-Querschneide-Einrichtung 44 ist oberhalb der unteren Teil-Querschneide-Einrichtung 45 angeordnet und dient zum Querdurchtrennen der oberen Teil-Wellpappe-Bahn 40. Die untere Teil-Querschneide-Einrichtung 45 dient zum Querdurchtrennen der unteren Teil-Wellpappe-Bahn 41.Downstream of the switch 42, the corrugated cardboard system has a cross cutting device 43 with two partial cross cutting devices 44, 45 arranged one above the other. Each partial cross cutting device 44, 45 has two cross cutting rollers 46, 47 arranged in pairs one above the other. The upper part Cross-cutting device 44 is arranged above the lower partial cross-cutting device 45 and serves to cross-cut the upper partial corrugated cardboard web 40. The lower partial cross-cutting device 45 serves to cross-cut the lower partial corrugated cardboard web 41.

Stromabwärts zu jeder Teil-Querschneide-Einrichtung 44, 45 ist ein Förderband 48, 49 der Wellpappe-Anlage angeordnet, um durch die Teil-Querschneide-Einrichtungen 44, 45 aus den Teil-Wellpappe-Bahnen 40, 41 erzeugte Wellpappe-Bögen 50 Stapel-Ablagevorrichtungen 51, 52 der Wellpappe-Anlage zuzuführen.A conveyor belt 48, 49 of the corrugated cardboard system is arranged downstream of each partial cross-cutting device 44, 45 in order to stack 50 corrugated cardboard sheets generated by the partial cross-cutting devices 44, 45 from the partial corrugated cardboard webs 40, 41 -Delivery devices 51, 52 to feed the corrugated cardboard system.

In der Wellpappe-Anlage sind unterschiedliche dreilagige Wellpappe-Bahnen 35 herstellbar. Diese können sich beispielsweise in ihrer Querbreite voneinander unterscheiden. Dafür werden bereits in der Wellpappe-Herstellvorrichtung 1 entsprechend angepasste einseitig kaschierte Wellpappe-Bahnen 2 erzeugt.Different three-layer corrugated webs 35 can be produced in the corrugated cardboard system. These can differ from one another, for example, in their transverse width. For this are already in the corrugated cardboard manufacturing device 1 correspondingly adapted, one-sided laminated corrugated sheets 2 are produced.

Zum Beleimen unterschiedlicher Breiten- bzw. Querbereiche der Wellbahn 10 in der Wellpappe-Herstellvorrichtung 1 sind die Leimdamm-Dichtungsanordnungen 19 unabhängig voneinander in einer Querrichtung der Wellbahn 10 verlagerbar. Die Leimdamm-Dichtungsanordnungen 19 sind so längs der ersten Drehachse 16 bzw. zweiten Drehachse 17 der Leimdosierwalze 14 bzw. der Leimauftragswalze 15 verlagerbar. Durch diese Verlagerung der Leimdamm-Dichtungsanordnungen 19 ist beispielsweise eine Leimbreite auf der Wellbahn 10 bzw. ein Abstand eines Leimbereichs auf der Wellbahn 10 zu deren Längsrändern einstellbar. Die Leimdamm-Dichtungsanordnungen 19 sind so in ihrer Lage bzw. in ihrem Abstand zueinander an die zu beleimende Wellbahn 10 anpassbar. Die Verlagerung kann händisch oder motorisch erfolgen.For gluing different width or transverse areas of the corrugated sheet 10 in the corrugated cardboard manufacturing device 1, the glue dam sealing arrangements 19 can be displaced independently of one another in a transverse direction of the corrugated sheet 10. The glue dam sealing arrangements 19 can thus be displaced along the first axis of rotation 16 or second axis of rotation 17 of the glue metering roller 14 or the glue application roller 15. This displacement of the glue dam sealing arrangements 19 makes it possible, for example, to set a glue width on the corrugated sheet 10 or a distance between a glue area on the corrugated sheet 10 and its longitudinal edges. The position or spacing of the glue dam sealing arrangements 19 can thus be adapted to the corrugated web 10 to be glued. The shift can be done manually or by motor.

Die Leimdamm-Dichtungsanordnungen 19 sind konstruktiv identisch und zueinander symmetrisch.The glue dam sealing arrangements 19 are structurally identical and symmetrical to one another.

Wie Fig. 5 zeigt, hat jede Leimdamm-Dichtungsanordnung 19 eine Trageinrichtung 53 mit einem Grundtragkörper 92 und einem sich an diesen anschließenden Seitentragkörper 54 sowie einem Kopfelement 55, das sich oben an den jeweiligen Grundtragkörper 92 und Seitentragkörper 54 anschließt.How Fig. 5 shows, each glue dam sealing arrangement 19 has a support device 53 with a base support body 92 and a side support body 54 adjoining this and a head element 55 which adjoins the respective base support body 92 and side support body 54 at the top.

Jeder Seitentragkörper 54 ist plattenartig und erstreckt sich in montiertem Zustand der Leimdamm-Dichtungsanordnung 19 senkrecht zu der Wellbahn 10 bzw. den Drehachsen 16, 17. Jeder Seitentragkörper 54 hat eine an die Leimdosierwalze 14 angepasste Leimdosierwalzen-Aufnahme 56 und eine benachbart zu dieser angeordnete, an die Leimauftragswalze 15 angepasste Leimauftragswalzen-Aufnahme 57. Die Leimdosierwalzen-Aufnahme 56 ist durch eine bogenförmige, insbesondere kreisbogenförmige, Dosierwalzen-Aufnahmekante 58 begrenzt, während die Leimauftragswalzen-Aufnahme 57 durch eine bogenförmige, insbesondere kreisbogenförmige, Leimauftragswalze-Aufnahmekante 59 begrenzt ist.Each side support body 54 is plate-like and extends in the assembled state of the glue dam sealing arrangement 19 perpendicular to the corrugated web 10 or the axes of rotation 16, 17. Each side support body 54 has a glue metering roller receptacle 56 and adapted to the glue metering roller 14 a glue applicator roller receptacle 57 arranged adjacent to it and adapted to the glue applicator roller 15. Recording edge 59 is limited.

In montiertem Zustand bzw. im Einsatz greift die Leimdosierwalze 14 in die Leimdosierwalzen-Aufnahme 56 der Leimdamm-Dichtungsanordnungen 19, während die Leimauftragswalze 15 in die Leimauftragswalzen-Aufnahme 57 der Leimdamm-Dichtungsanordnungen 19 eingreift (Fig. 3, 4). Die Leimdamm-Dichtungsanordnungen 19 liegen dann einander gegenüber und begrenzen den Leim in dem Leimbehälter 13 längs der Drehachsen 16, 17.In the assembled state or in use, the glue metering roller 14 engages in the glue metering roller receptacle 56 of the glue dam sealing arrangements 19, while the glue application roller 15 engages in the glue application roller receptacle 57 of the glue dam sealing arrangement 19 ( Fig. 3 . 4 ). The glue dam sealing arrangements 19 then lie opposite one another and limit the glue in the glue container 13 along the axes of rotation 16, 17.

Ferner umfasst jede Leimdamm-Dichtungsanordnung 19 ein erstes Leimdamm-Dichtungselement 60, das an dem jeweiligen Seitentragkörper 54 verlagerbar angeordnet bzw. geführt ist. Jedes erste Leimdamm-Dichtungselement 60 ist plattenartig ausgeführt und hat eine an die Leimdosierwalze 14 angepasste, bogenförmige, insbesondere kreisbogenförmige, Leimdosierwalzen-Dichtkante 61, die in einer Dichtstellung der jeweiligen Leimdamm-Dichtungsanordnung 19 dichtend an der Leimdosierwalze 14 umfangsseitig anliegt.Furthermore, each glue dam sealing arrangement 19 comprises a first glue dam sealing element 60, which is arranged or guided displaceably on the respective side support body 54. Each first glue dam sealing element 60 is designed in the manner of a plate and has an arcuate, in particular circular, glue metering roller sealing edge 61 which is adapted to the glue metering roller 14 and which, in a sealing position of the respective glue dam sealing arrangement 19, lies sealingly against the glue metering roller 14.

Jede Leimdamm-Dichtungsanordnung 19 weist ferner ein zweites Leimdamm-Dichtungselement 62 auf, das benachbart zu dem zugehörigen ersten Leimdamm-Dichtungselement 60 angeordnet und an dem jeweiligen Seitentragkörper 54 verlagerbar angeordnet bzw. geführt ist. Jedes zweite Leimdamm-Dichtungselement 62 ist plattenartig ausgeführt. Jedes zweite Leimdamm-Dichtungselement 62 hat eine an die Leimdosierwalze 14 angepasste, bogenförmige, insbesondere kreisbogenförmige, Leimdosierwalzen-Abschlusskante 63 und eine an die Leimauftragswalze 15 angepasste, bogenförmige, insbesondere kreisbogenförmige, Leimauftragswalzen-Dichtkante 64. In einer Dichtstellung der jeweiligen Leimdamm-Dichtungsanordnung 19 liegen das erste Leimdamm-Dichtungselement 60 und das zweite Leimdamm-Dichtungselement 62 in einer gemeinsamen Ebene. Sie sind günstigerweise beabstandet zueinander angeordnet. Die Leimdosierwalzen-Abschlusskante 63 verläuft geringfügig beabstandet zu der Leimdosierwalze 14 (um 0,1 mm bis 0,3 mm beabstandet), während die Leimauftragswalzen-Dichtkante 64 dichtend an der Leimauftragswalze 15 umfangsseitig anliegt. Die Leimdosierwalzen-Dichtkante 61 und die Leimdosierwalzen-Abschlusskante 63 der jeweiligen Leimdamm-Dichtungsanordnung 19 gehen in den Dichtstellungen der Leimdamm-Dichtungselemente 60, 62 günstigerweise im Wesentlichen übergangslos ineinander über. Sie bilden dann quasi eine gemeinsame, bogenförmige, insbesondere kreisbogenförmige, Leimdosierwalzen-Kante.Each glue dam sealing arrangement 19 also has a second glue dam sealing element 62 which is arranged adjacent to the associated first glue dam sealing element 60 and is arranged or guided such that it can be displaced on the respective side support body 54. Every second glue dam sealing element 62 is designed like a plate. Every second Glue dam sealing element 62 has an arcuate, in particular circular arc, glue metering roller end edge 63 adapted to the glue metering roller 14 and an arcuate, in particular circular arc, glue application roller sealing edge 64 adapted to the glue application roller 15 first glue dam sealing element 60 and the second glue dam sealing element 62 in a common plane. They are advantageously spaced apart from one another. The glue metering roller end edge 63 runs slightly spaced apart from the glue metering roller 14 (spaced apart by 0.1 mm to 0.3 mm), while the glue application roller sealing edge 64 sealingly abuts the glue application roller 15 on the circumferential side. The glue metering roller sealing edge 61 and the glue metering roller end edge 63 of the respective glue dam sealing arrangement 19 advantageously merge into one another essentially seamlessly in the sealing positions of the glue dam sealing elements 60, 62. They then form a common, arc-shaped, in particular circular arc-shaped, glue metering roller edge.

Das erste und zweite Leimdamm-Dichtungselement 60, 62 von jeder Leimdamm-Dichtungsanordnung 19 sind unabhängig voneinander entlang des benachbarten Seitentragkörpers 54 verstellbar.The first and second glue dam sealing elements 60, 62 of each glue dam sealing arrangement 19 can be adjusted independently of one another along the adjacent side support body 54.

Das erste Leimdamm-Dichtungselement 60 hat eine sich an die Leimdosierwalzen-Dichtkante 61 anschließende erste Seitenkante 65, die dem benachbarten zweiten Leimdamm-Dichtungselement 62 zugewandt ist. Das zweite Leimdamm-Dichtungselement 62 hat eine sich an die Leimdosierwalzen-Abschlusskante 63 anschließende zweite Seitenkante 66, die der ersten Seitenkante 65 bzw. dem ersten Leimdamm-Dichtungselement 60 zugewandt ist. Die Seitenkanten 65, 66 erstrecken sich gerade. Sie verlaufen gegenüber einer Vertikalen geneigt und schließen mit dieser einen Winkel zwischen 5° und 45°, bevorzugter zwischen 10° und 30°, ein. Sie sind von oben aus in Richtung auf die Leimauftragswalze 15 hin geneigt.The first glue dam sealing element 60 has a first side edge 65 which adjoins the glue metering roller sealing edge 61 and which faces the adjacent second glue dam sealing element 62. The second glue dam sealing element 62 has a second side edge 66 which adjoins the glue metering roller end edge 63 and which faces the first side edge 65 or the first glue dam sealing element 60. The side edges 65, 66 extend straight. You run inclined to a vertical and enclose an angle of between 5 ° and 45 °, more preferably between 10 ° and 30 °. They are inclined from above in the direction of the glue application roller 15.

In jedem ersten Leimdamm-Dichtungselement 60 ist benachbart zu der ersten Seitenkante 65 eine kreisförmige erste Lageröffnung bzw. Lagerausnehmung 67 angeordnet, während in jedem zweiten Leimdamm-Dichtungselement 62 benachbart zu der zweiten Seitenkante 66 eine kreisförmige zweite Lageröffnung bzw. Lagerausnehmung 68 angeordnet ist. Die Lageröffnungen 67, 68 sind in montiertem Zustand der jeweiligen Leimdamm-Dichtungsanordnung 19 auf einer im Wesentlichen gemeinsamen Höhe angeordnet und haben einen im Wesentlichen identischen Abstand zu einer oberen ersten Kopfkante 69 und einer oberen zweiten Kopfkante 70 des ersten Leimdamm-Dichtungselements 60 bzw. des zweiten Leimdamm-Dichtungselements 62. Sie haben vorzugsweise einen identischen Durchmesser.A circular first bearing opening or bearing recess 67 is arranged in each first glue dam sealing element 60 adjacent to the first side edge 65, while a circular second bearing opening or bearing recess 68 is arranged in every second glue dam sealing element 62 adjacent to the second side edge 66. In the assembled state of the respective glue dam sealing arrangement 19, the bearing openings 67, 68 are arranged at a substantially common height and have a substantially identical distance from an upper first head edge 69 and an upper second head edge 70 of the first glue dam sealing element 60 and the second glue dam sealing element 62. They preferably have an identical diameter.

Die Lageröffnungen 67, 68 sind umfangsseitig geschlossen. Jede erste Lageröffnung 67 hat eine erste Mittelachse 71, während jede zweite Lageröffnung 68 eine zweite Mittelachse 72 hat. Die Mittelachsen 71, 72 erstrecken sich parallel zueinander. Sie verlaufen parallel zu der ersten und zweiten Drehachse 16, 17. Die Mittelachsen 71, 72 sind beabstandet zu der ersten bzw. zweiten Kopfkante 69, 70 und den (Dicht)kanten 61, 63 bzw. 64 angeordnet.The bearing openings 67, 68 are closed on the circumference. Each first bearing opening 67 has a first central axis 71, while each second bearing opening 68 has a second central axis 72. The central axes 71, 72 extend parallel to one another. They run parallel to the first and second axes of rotation 16, 17. The central axes 71, 72 are spaced apart from the first and second head edges 69, 70 and the (sealing) edges 61, 63 and 64, respectively.

Jede Leimdamm-Dichtungsanordnung 19 hat ein kreisförmiges erstes Andrückelement 73, das in der ersten Lageröffnung 67 aufgenommen ist und einen ersten Durchmesser hat. Der erste Durchmesser des ersten Andrückelements 73 ist kleiner, günstigerweise geringfügig kleiner, als der erste Durchmesser der ersten Lageröffnung 67, sodass Spiel zwischen dem ersten Andrückelement 73 und dem ersten Leimdamm-Dichtungselement 60 vorliegt. Jedes erste Andrückelement 73 ist um eine erste Schwenkachse 74 verschwenkbar, die exzentrisch in Bezug auf das erste Andrückelement 73 bzw. die erste Mittelachse 71 und parallel zu den Drehachsen 16, 17 verläuft. Es bildet so einen ersten Andrückexzenter.Each glue dam sealing arrangement 19 has a circular first pressing element 73, which is received in the first bearing opening 67 and has a first diameter. The first diameter of the first pressure element 73 is smaller, advantageously slightly smaller than the first Diameter of the first bearing opening 67 so that there is play between the first pressure element 73 and the first glue dam sealing element 60. Each first pressing element 73 can be pivoted about a first pivot axis 74, which runs eccentrically with respect to the first pressing element 73 or the first central axis 71 and parallel to the axes of rotation 16, 17. It forms a first pressure eccentric.

Jedes erste Andrückelement 73 ist um die jeweilige erste Schwenkachse 74 durch ein entsprechendes erstes Schwenkmittel 75 verschwenkbar, das, insbesondere innenseitig, an dem benachbarten Seitentragkörper 54 befestigt ist und hier als Motor bzw. Antrieb ausgeführt ist.Each first pressing element 73 can be pivoted about the respective first pivot axis 74 by means of a corresponding first pivoting means 75, which is fastened, in particular on the inside, to the adjacent side support body 54 and is designed here as a motor or drive.

Jedes erste Schwenkmittel 75 verschwenkt im Betrieb das entsprechende zugeordnete erste Andrückelement 73 um die jeweilige erste Schwenkachse 74, was zu einer seitlichen Verlagerung des ersten Andrückelements 73 und zu einer entsprechenden Verlagerung des zugeordneten ersten Leimdamm-Dichtungselements 60 durch das in der ersten Lageröffnung 67 an dem ersten Leimdamm-Dichtungselement 60 innen angreifenden, ersten Andrückelement 73 führt.During operation, each first pivoting means 75 pivots the corresponding assigned first pressure element 73 about the respective first pivot axis 74, which leads to a lateral displacement of the first pressure element 73 and to a corresponding displacement of the assigned first glue dam sealing element 60 by the in the first bearing opening 67 on the leads first glue dam sealing element 60 engaging inside, first pressing element 73.

Jedes erste Andrückelement 73 ist imstande, im Betrieb/Einsatz des ersten Schwenkmittels 75 eine resultierende erste Andrückkraft 76 auf das erste Leimdamm-Dichtungselement 60 auszuüben, die genau auf die erste Drehachse 16 der Leimdosierwalze 14 gerichtet ist. Jedes erste Andrückelement 73 wird dabei in einer ersten Schwenkrichtung 77 um die zugehörige erste Schwenkachse 74 verschwenkt. Jedes erste Leimdamm-Dichtungselement 60 ist um das zugeordnete erste Andrückelement 73, insbesondere im Wesentlichen um dessen Mittelachse 71, stets ungehindert verschwenkbar.Each first pressing element 73 is able to exert a resulting first pressing force 76 on the first glue dam sealing element 60 during operation / use of the first pivoting means 75, said first pressing force being directed exactly at the first axis of rotation 16 of the glue metering roller 14. Each first pressure element 73 is pivoted in a first pivoting direction 77 about the associated first pivot axis 74. Each first glue dam sealing element 60 can always be pivoted unhindered about the associated first pressing element 73, in particular essentially about its central axis 71.

Jede Leimdamm-Dichtungsanordnung 19 hat ferner ein kreisförmiges zweites Andrückelement 78, das in der zweiten Lageröffnung 68 aufgenommen ist und einen zweiten Durchmesser hat. Der zweite Durchmesser des zweiten Andrückelements 78 ist kleiner, günstigerweise geringfügig kleiner, als der zweite Durchmesser der zweiten Lageröffnung 68, sodass Spiel zwischen dem zweiten Andrückelement 78 und dem zweiten Leimdamm-Dichtungselement 62 vorliegt. Jedes zweite Andrückelement 78 ist um eine zu der ersten Schwenkachse 74 parallele zweite Schwenkachse 78 verschwenkbar, die exzentrisch in Bezug auf das zweite Andrückelement 78 bzw. die zweite Mittelachse 72 und parallel zu den Drehachsen 16, 17 verläuft. Es bildet so einen zweiten Andrückexzenter.Each glue dam sealing arrangement 19 also has a circular second pressing element 78, which is received in the second bearing opening 68 and has a second diameter. The second diameter of the second pressure element 78 is smaller, advantageously slightly smaller, than the second diameter of the second bearing opening 68, so that there is play between the second pressure element 78 and the second glue dam sealing element 62. Each second pressing element 78 can be pivoted about a second pivot axis 78 parallel to the first pivot axis 74, which runs eccentrically with respect to the second pressing element 78 or the second central axis 72 and parallel to the axes of rotation 16, 17. It forms a second pressure eccentric.

Jedes zweite Andrückelement 78 ist um die jeweilige zweite Schwenkachse 79 durch ein entsprechendes zweites Schwenkmittel 80 verschwenkbar, das, insbesondere innenseitig, an dem benachbarten Seitentragkörper 54 befestigt ist und hier als Motor bzw. Antrieb ausgeführt ist.Each second pressing element 78 can be pivoted about the respective second pivot axis 79 by a corresponding second pivoting means 80, which is fastened, in particular on the inside, to the adjacent side support body 54 and is designed here as a motor or drive.

Jedes zweite Schwenkmittel 80 verschwenkt im Betrieb das entsprechende zugeordnete zweite Andrückelement 78 um die jeweilige zweite Schwenkachse 79, was zu einer seitlichen Verlagerung des zweiten Andrückelements 78 und zu einer entsprechenden Verlagerung des zugeordneten zweiten Leimdamm-Dichtungselements 62 durch das in der zweiten Lageröffnung 68 an dem zweiten Leimdamm-Dichtungselement 62 innen angreifenden, zweiten Andrückelement 78 führt.During operation, every second pivoting means 80 pivots the corresponding assigned second pressure element 78 about the respective second pivot axis 79, which leads to a lateral displacement of the second pressure element 78 and to a corresponding displacement of the assigned second glue dam sealing element 62 by the in the second bearing opening 68 on the leads second glue dam sealing element 62 engaging inside, second pressing element 78.

Jedes zweite Andrückelement 78 ist imstande, im Betrieb/Einsatz des zweiten Schwenkmittels 80 eine resultierende zweite Andrückkraft 81 auf das zweite Leimdamm-Dichtungselement 62 auszuüben, die genau auf die zweite Drehachse 17 der Leimauftragswalze 15 gerichtet ist und so schräg zu der resultierenden ersten Andrückkraft 76 verläuft. Jedes zweite Andrückelement 78 wird dabei in einer zweiten Schwenkrichtung 93 um die zugehörige zweite Schwenkachse 79 verschwenkt. Jedes zweite Leimdamm-Dichtungselement 62 ist um das zugeordnete zweite Andrückelement 78, insbesondere im Wesentlichen um dessen Mittelachse 72, stets ungehindert verschwenkbar.Every second pressing element 78 is able to exert a resulting second pressing force 81 on the second glue dam sealing element 62 during operation / use of the second pivoting means 80, said second pressing force being directed exactly at the second axis of rotation 17 of the glue application roller 15 and thus obliquely to the resulting first pressing force 76. Every second pressing element 78 is pivoted in a second pivot direction 93 about the associated second pivot axis 79. Every second glue dam sealing element 62 can always be pivoted freely about the assigned second pressing element 78, in particular essentially about its central axis 72.

Wie Fig. 3 zeigt, ist die Leimdosierwalzen-Dichtkante 61 dichtend an der Leimdosierwalze 14 umfangsseitig angeordnet, sodass das erste Leimdamm-Dichtungselement 60 gegenüber der Leimdosierwalze 14 abdichtet. Die erste Schwenkachse 74 befindet sich seitlich in etwa auf Höhe der ersten Mittelachse 71 des ersten Andrückelements 73. Das erste Leimdamm-Dichtungselement 60 befindet sich in einem neuen unverschlissenen Zustand.How Fig. 3 shows, the glue metering roller sealing edge 61 is sealingly arranged on the glue metering roller 14 on the circumference, so that the first glue dam sealing element 60 seals against the glue metering roller 14. The first pivot axis 74 is located laterally approximately at the level of the first central axis 71 of the first pressing element 73. The first glue dam sealing element 60 is in a new, non-worn state.

Gemäß Fig. 3 ist die Leimdosierwalzen-Abschlusskante 63 geringfügig beabstandet zu der Leimdosierwalze 14 angeordnet. Die Leimauftragswalzen-Dichtkante 64 ist dichtend an der Leimauftragswalze 15 umfangsseitig angeordnet, sodass die Leimauftragswalzen-Dichtkante 64 gegenüber der Leimauftragswalze 15 abdichtet. Die zweite Schwenkachse 79 befindet sich in einem unteren Bereich der zweiten Lageröffnung 68.According to Fig. 3 the glue metering roller end edge 63 is arranged at a slight distance from the glue metering roller 14. The glue application roller sealing edge 64 is sealingly arranged on the glue application roller 15 on the circumferential side, so that the glue application roller sealing edge 64 seals against the glue application roller 15. The second pivot axis 79 is located in a lower region of the second bearing opening 68.

Ein Verschwenken des ersten Andrückelements 73 in der ersten Schwenkrichtung 77 um die erste Schwenkachse 74 durch das jeweilige erste Schwenkmittel 75 führt zum Ausüben der resultierenden, in Richtung auf die erste Drehachse 16 gerichteten ersten Andrückkraft 76 auf das erste Leimdamm-Dichtungselement 60, was zu einer Verlagerung des ersten Leimdamm-Dichtungselements 60 in Richtung auf die erste Drehachse 16 der Leimdosierwalze 14 und dann letztendlich zu einer gleichmäßigen dichten Anlage der Leimdosierwalzen-Dichtkante 61 an der Leimdosierwalze 14 führt. Dies ist auch in einem verschlissenen Zustand des ersten Leimdamm-Dichtungselements 60 so. Die erste Schwenkachse 74 befindet sich dann in einem oberen Bereich der ersten Lageröffnung 67 (Fig. 4).A pivoting of the first pressing element 73 in the first pivoting direction 77 about the first pivot axis 74 by the respective first pivoting means 75 leads to the application of the resulting first pressing force 76 directed in the direction of the first axis of rotation 16 on the first glue dam sealing element 60, which leads to a Displacement of the first glue dam sealing element 60 in the direction of the first axis of rotation 16 of the glue metering roller 14 and then ultimately to a uniform one tight contact of the glue metering roller sealing edge 61 on the glue metering roller 14 leads. This is also the case in a worn state of the first glue dam sealing element 60. The first pivot axis 74 is then located in an upper region of the first bearing opening 67 ( Fig. 4 ).

Ein Verschwenken des zweiten Andrückelements 78 in der zweiten Schwenkrichtung 93 um die zweite Schwenkachse 79 durch das jeweilige zweite Schwenkmittel 80 führt zum Ausüben der resultierenden, in Richtung auf die zweite Drehachse 17 gerichteten zweiten Andrückkraft 81 auf das zweite Leimdamm-Dichtungselement 62, was zu einer Verlagerung des zweiten Leimdamm-Dichtungselements 62 in Richtung auf die zweite Drehachse 17 der Leimauftragswalze 15 und dann letztendlich zu einer gleichmäßigen dichten Anlage der Leimauftragswalzen-Dichtkante 64 an der Leimauftragswalze 15 führt. Dies ist auch in einem verschlissenen Zustand des zweiten Leimdamm-Dichtungselements 62 so. Die zweite Schwenkachse 79 befindet sich dann in etwa auf Höhe der zweiten Mittelachse 72 des zweiten Andrückelements 78 (Fig. 4).A pivoting of the second pressure element 78 in the second pivot direction 93 about the second pivot axis 79 by the respective second pivot means 80 leads to the application of the resulting second pressure force 81 directed in the direction of the second axis of rotation 17 on the second glue dam sealing element 62, which leads to a Displacement of the second glue dam sealing element 62 in the direction of the second axis of rotation 17 of the glue application roller 15 and then ultimately leads to a uniform, tight contact of the glue application roller sealing edge 64 with the glue application roller 15. This is also the case when the second glue dam sealing element 62 is worn out. The second pivot axis 79 is then approximately at the level of the second central axis 72 of the second pressing element 78 ( Fig. 4 ).

Eine erste Andrückeinrichtung umfasst ein erstes Andrückelement 73 und ein erstes Schwenkmittel 75. Eine zweite Andrückeinrichtung umfasst ein zweites Andrückelement 78 und ein zweites Schwenkmittel 80.A first pressing device comprises a first pressing element 73 and a first pivoting means 75. A second pressing device comprises a second pressing element 78 and a second pivoting means 80.

Analoges gilt für den Einsatz der Leimdamm-Dichtungsanordnungen 19 in dem Leimwerk 28. Wenn das Leimwerk 28 als Walze lediglich die Beleimungswalze 29 umfasst, so hat jede Leimdamm-Dichtungsanordnung 19 nur ein erstes oder zweites Leimdamm-Dichtungselement 60, 62 und nur eine Andrückeinrichtung. Wenn das Leimwerk 28 die Beleimungswalze 29 und die Leimabquetschwalze umfasst, so hat jede Leimdamm-Dichtungsanordnung 19 wie bei der Leimauftrags-Einrichtung 11 der Wellpappe-Herstellvorrichtung 1 zwei Leimdamm-Dichtungselemente 60, 62 und zwei Andrückeinrichtungen.The same applies analogously to the use of the glue dam sealing arrangements 19 in the gluing unit 28. If the gluing unit 28 as the roller only comprises the gluing roller 29, then each glue dam sealing arrangement 19 has only a first or second glue dam sealing element 60, 62 and only one pressing device. If the glue unit 28 comprises the gluing roller 29 and the glue squeezing roller, then each glue dam sealing arrangement 19 has the corrugated cardboard manufacturing device as in the glue application device 11 1 two glue dam sealing elements 60, 62 and two pressing devices.

Nachfolgend wird unter Bezugnahme auf die Fig. 6, 7 eine zweite Ausführungsform beschrieben. Konstruktiv identische Teile erhalten dieselben Bezugszeichen wie bei der vorherigen Ausführungsform, auf deren Beschreibung explizit verwiesen wird. Konstruktiv unterschiedliche, jedoch funktionell gleichartige Teile erhalten dieselben Bezugszeichen mit einem nachgeordneten "a".Below is with reference to the Fig. 6 . 7 described a second embodiment. Structurally identical parts are given the same reference numerals as in the previous embodiment, the description of which is explicitly referred to. Structurally different, but functionally similar parts are given the same reference numerals with a subordinate "a".

Im Gegensatz zu der ersten Ausführungsform ist jede erste Lageröffnung 67a länglich ausgeführt und erstreckt sich im Wesentlichen parallel zu einer benachbarten Tangentialen der Leimdosierwalzen-Dichtkante 61. Jede erste Lageröffnung 67a erstreckt sich vorzugsweise leicht gegenüber einer Horizontalen geneigt.In contrast to the first embodiment, each first bearing opening 67a is elongated and extends substantially parallel to an adjacent tangent of the glue metering roller sealing edge 61. Each first bearing opening 67a preferably extends slightly inclined to a horizontal.

Jedes erste Andrückelement 73a ist hebelartig ausgeführt und um die erste Schwenkachse 74 verschwenkbar, die sich wieder parallel zu der ersten Drehachse 16 der Leimdosierwalze 14 erstreckt. Jedes erste Andrückelement 73a ist an dem benachbarten Seitentragkörper 54 schwenkbar gelagert, an dem dafür ein entsprechender zylindrischer erster Lagerstift 82 angeordnet ist.Each first pressure element 73a is designed like a lever and can be pivoted about the first pivot axis 74, which again extends parallel to the first axis of rotation 16 of the glue metering roller 14. Each first pressure element 73a is pivotally mounted on the adjacent side support body 54, on which a corresponding cylindrical first bearing pin 82 is arranged.

Beabstandet zu jeder ersten Schwenkachse 74 greift an jedem ersten Andrückelement 73a ein erstes Schwenkmittel 75a an, das durch eine erste Druckfeder, insbesondere Schraubendruckfeder, gebildet ist. Jedes erste Schwenkmittel 75a stützt sich an dem ersten Leimdamm-Dichtungselement 60a unten ab.Spaced apart from each first pivot axis 74, a first pivoting means 75a, which is formed by a first compression spring, in particular a helical compression spring, acts on each first pressing element 73a. Each first pivoting means 75a is supported on the first glue dam sealing element 60a at the bottom.

Jedes erste Leimdamm-Dichtungselement 60a steht über einen zylindrischen ersten Kupplungsstift 83 mit dem zugeordneten ersten Andrückelement 73a in Schwenkverbindung. Jeder erste Kupplungsstift 83 ist günstigerweise an dem jeweiligen ersten Leimdamm-Dichtungselement 60a angeordnet. Jeder erste Lagerstift 82 ist zwischen dem ersten Kupplungsstift 83 und einem ersten Angriffspunkt 84 des ersten Schwenkmittels 75a an dem ersten Andrückelement 73a angeordnet.Each first glue dam sealing element 60a is pivotally connected to the associated first pressing element 73a via a cylindrical first coupling pin 83. Each first coupling pin 83 is advantageously arranged on the respective first glue dam sealing element 60a. Each first bearing pin 82 is arranged between the first coupling pin 83 and a first engagement point 84 of the first pivoting means 75a on the first pressing element 73a.

Das erste Leimdamm-Dichtungselement 60a ist imstande, sich stets selbst an die Leimdosierwalze 14 anzupassen bzw. stets dicht mit seiner Leimdosierwalzen-Dichtkante 61 an dieser umfangsseitig anzuliegen. Es ist imstande, eine Verstellung der Leimdosierwalze 14 selbständig mitzumachen.The first glue dam sealing element 60a is able to always adapt itself to the glue metering roller 14 or to always lie tightly with its glue metering roller sealing edge 61 on the circumference thereof. It is able to take part in an adjustment of the glue metering roller 14 independently.

Wie Fig. 6 zeigt, ist die Leimdosierwalzen-Dichtkante 61 dichtend an der Leimdosierwalze 14 umfangsseitig angeordnet, sodass das erste Leimdamm-Dichtungselement 60a gegenüber der Leimdosierwalze 14 abdichtet. Das erste Leimdamm-Dichtungselement 60a befindet sich in einem neuen unverschlissenen Zustand.How Fig. 6 shows, the glue metering roller sealing edge 61 is sealingly arranged on the glue metering roller 14 on the circumferential side, so that the first glue dam sealing element 60a seals against the glue metering roller 14. The first glue dam sealing element 60a is in a new, non-worn state.

Gemäß Fig. 6 ist die Leimdosierwalzen-Abschlusskante 63 geringfügig beabstandet zu der Leimdosierwalze 14 angeordnet. Die Leimauftragswalzen-Dichtkante 64 ist dichtend an der Leimauftragswalze 15 umfangsseitig angeordnet, sodass die Leimauftragswalzen-Dichtkante 64 gegenüber der Leimauftragswalze 15 abdichtet.According to Fig. 6 the glue metering roller end edge 63 is arranged at a slight distance from the glue metering roller 14. The glue application roller sealing edge 64 is sealingly arranged on the glue application roller 15 on the circumferential side, so that the glue application roller sealing edge 64 seals against the glue application roller 15.

Das erste Schwenkmittel 75a drückt das erste Andrückelement 73a an dem ersten Angriffspunkt 84 stets nach oben bzw. weg von der Leimdosierwalze 14. Hierdurch wird der erste Kupplungsstift 83 mitsamt dem auf diesem sitzenden, ersten Leimdamm-Dichtungselement 60a in Richtung auf die erste Drehachse 16 der Leimdosierwalze 14 gedrückt, was zu einer gleichmäßigen dichten Anlage der Leimdosierwalzen-Dichtkante 61 an der Leimdosierwalze 14 führt (Fig. 7). Dies ist auch in einem verschlissenen Zustand des ersten Leimdamm-Dichtungselements 60a so. Dabei wird die resultierende erste Andrückkraft 76 in Richtung auf die erste Drehachse 16 erzeugt. Das erste Leimdamm-Dichtungselement 60a ist stets verschwenkbar auf dem ersten Kupplungsstift 83 angeordnet.The first pivoting means 75a always presses the first pressing element 73a upwards or away from the glue metering roller 14 at the first point of application 84. As a result, the first coupling pin 83 together with the first glue dam sealing element 60a seated thereon is pushed in the direction of the pressed the first axis of rotation 16 of the glue metering roller 14, which leads to a uniform, tight contact of the glue metering roller sealing edge 61 with the glue metering roller 14 ( Fig. 7 ). This is also the case when the first glue dam sealing element 60a is worn out. The resulting first pressing force 76 is generated in the direction of the first axis of rotation 16. The first glue dam sealing element 60a is always pivotably arranged on the first coupling pin 83.

Im Gegensatz zu der ersten Ausführungsform ist jede zweite Lageröffnung 68a länglich ausgeführt und erstreckt sich im Wesentlichen parallel zu einer benachbarten Tangentialen der Leimauftragswalzen-Dichtkante 64. Jede zweite Lageröffnung 68a verläuft im Wesentlichen leicht gegenüber einer Vertikalen geneigt.In contrast to the first embodiment, every second bearing opening 68a is elongated and extends essentially parallel to an adjacent tangential line of the glue application roller sealing edge 64. Every second bearing opening 68a is essentially slightly inclined with respect to a vertical.

Jedes zweite Andrückelement 78a ist hebelartig ausgeführt und um die zweite Schwenkachse 79 verschwenkbar, die sich wieder parallel zu der zweiten Drehachse 17 der Leimauftragswalze 15 erstreckt. Jedes zweite Andrückelement 78a ist an dem benachbarten Seitentragkörper 54 schwenkbar gelagert, an dem dafür ein entsprechender zylindrischer zweiter Lagerstift 85 angeordnet ist.Every second pressing element 78a is designed like a lever and can be pivoted about the second pivot axis 79, which again extends parallel to the second axis of rotation 17 of the glue application roller 15. Every second pressure element 78a is pivotally mounted on the adjacent side support body 54, on which a corresponding cylindrical second bearing pin 85 is arranged.

Beabstandet zu jeder zweiten Schwenkachse 79 greift an jedem zweiten Andrückelement 78a ein zweites Schwenkmittel 80a an, das durch eine zweite Druckfeder, insbesondere Schraubendruckfeder, gebildet ist. Jedes zweite Schwenkmittel 80a stützt sich an dem zweiten Leimdamm-Dichtungselement 62a unten ab.Spaced apart from every second pivot axis 79, a second pivoting means 80a, which is formed by a second compression spring, in particular a helical compression spring, acts on every second pressing element 78a. Every second pivoting means 80a is supported on the second glue dam sealing element 62a at the bottom.

Jedes zweite Leimdamm-Dichtungselement 62a steht über einen zylindrischen zweiten Kupplungsstift 86 mit dem zugeordneten zweiten Andrückelement 78a in Schwenkverbindung. Jeder zweite Kupplungsstift 83 ist günstigerweise an dem jeweiligen zweiten Leimdamm-Dichtungselement 62a angeordnet. Jeder zweite Lagerstift 85 ist zwischen dem zweiten Kupplungsstift 86 und einem zweiten Angriffspunkt 87 des zweiten Schwenkmittels 80a an dem zweiten Andrückelement 78a angeordnet.Every second glue dam sealing element 62a stands over a cylindrical second coupling pin 86 with the associated second pressing element 78a in swivel connection. Each second coupling pin 83 is advantageously arranged on the respective second glue dam sealing element 62a. Every second bearing pin 85 is arranged between the second coupling pin 86 and a second engagement point 87 of the second pivoting means 80a on the second pressing element 78a.

Das zweite Leimdamm-Dichtungselement 62a ist imstande, sich stets selbst an die Leimauftragswalze 15 anzupassen bzw. stets dicht mit seiner Leimauftragswalzen-Dichtkante 64 an dieser umfangsseitig anzuliegen. Es ist imstande, eine Verstellung der Leimauftragswalze 15 selbständig mitzumachen.The second glue dam sealing element 62a is able to always adapt itself to the glue application roller 15 or to always lie tightly with its glue application roller sealing edge 64 on the circumference thereof. It is able to take part in an adjustment of the glue application roller 15 independently.

Das zweite Schwenkmittel 80a drückt das zweite Andrückelement 78a an dem zweiten Angriffspunkt 87 stets weg von der Leimauftragswalze 15. Hierdurch wird der zweite Kupplungsstift 86 mitsamt dem auf diesem sitzenden, zweiten Leimdamm-Dichtungselement 62a in Richtung auf die zweite Drehachse 17 der Leimauftragswalze 15 gedrückt, was zu einer gleichmäßigen dichten Anlage der Leimauftragswalzen-Dichtkante 64 an der Leimauftragswalze 15 führt (Fig. 7). Dies ist auch im verschlissenen Zustand des zweiten Leimdamm-Dichtungselements 62a so. Dabei wird die resultierende zweite Andrückkraft 81 in Richtung auf die zweite Drehachse 17 erzeugt. Das zweite Leimdamm-Dichtungselement 62a ist stets verschwenkbar auf dem zweiten Kupplungsstift 86 angeordnet.The second pivoting means 80a always presses the second pressing element 78a away from the glue application roller 15 at the second point of application 87. As a result, the second coupling pin 86 together with the second glue dam sealing element 62a seated thereon is pressed in the direction of the second axis of rotation 17 of the glue application roller 15. which leads to a uniform, tight contact of the glue application roller sealing edge 64 with the glue application roller 15 ( Fig. 7 ). This is also the case when the second glue dam sealing element 62a is worn out. The resulting second pressing force 81 is generated in the direction of the second axis of rotation 17. The second glue dam sealing element 62a is always pivotably arranged on the second coupling pin 86.

Analoges gilt für den Einsatz der Leimdamm-Dichtungsanordnungen 19a in dem Leimwerk 28.The same applies analogously to the use of the glue dam sealing arrangements 19a in the gluing unit 28.

Nachfolgend wird unter Bezugnahme auf die Fig. 8, 9 eine dritte Ausführungsform beschrieben. Konstruktiv identische Teile erhalten dieselben Bezugszeichen wie bei den vorherigen Ausführungsformen, auf deren Beschreibung explizit verwiesen wird. Konstruktiv unterschiedliche, jedoch funktionell gleichartige Teile erhalten dieselben Bezugszeichen mit einem nachgeordneten "b".Below is with reference to the Fig. 8 . 9 described a third embodiment. Parts that are identical in construction receive the same Reference symbols as in the previous embodiments, to the description of which reference is expressly made. Structurally different, but functionally similar parts are given the same reference numerals with a subordinate "b".

Im Vergleich mit der ersten Ausführungsform sind hier die ersten und zweiten Lageröffnungen 67b, 68b anders ausgeführt. Jede erste Lageröffnung 67b ist unrund. Sie ist durch äußere erste Abstützflächen 88 begrenzt, die sich senkrecht oder schräg zu einer ersten Umfangsrichtung der ersten Lageröffnung 67b erstrecken.In comparison to the first embodiment, the first and second bearing openings 67b, 68b are designed differently here. Each first bearing opening 67b is out of round. It is delimited by outer first support surfaces 88, which extend perpendicularly or obliquely to a first circumferential direction of the first bearing opening 67b.

Jedes erste Andrückelement 73b ist scheibenartig und hat umfangsseitig erste Angriffsflächen 90. Jedes erste Andrückelement 73b ist über den ersten Lagerstift 82 an dem jeweiligen Seitentragkörper 54 um eine erste Schwenkachse 74 schwenkbar gelagert. Jeder erster Lagerstift 82 ist exzentrisch zu dem ersten Andrückelement 73b bzw. zu dessen Mittelachse 71b angeordnet. Jedes erste Andrückelement 73b bildet einen ersten Andrückexzenter.Each first pressing element 73b is disc-like and has circumferential first engagement surfaces 90. Each first pressing element 73b is mounted on the respective side support body 54 via the first bearing pin 82 so as to be pivotable about a first pivot axis 74. Each first bearing pin 82 is arranged eccentrically to the first pressing element 73b or to the central axis 71b thereof. Each first pressing element 73b forms a first pressing eccentric.

Jeweils ein erstes Schwenkmittel 75b in Form einer Druckfeder, insbesondere in Form einer Schraubendruckfeder, befindet sich zwischen einer ersten Abstützflächen 88 und einer benachbarten ersten Angriffsfläche 90.A first pivoting means 75b in the form of a compression spring, in particular in the form of a helical compression spring, is located between a first support surface 88 and an adjacent first engagement surface 90.

Jede zweite Lageröffnung 68b ist unrund. Sie ist durch äußere zweite Abstützflächen 89 begrenzt, die sich senkrecht oder schräg zu einer zweiten Umfangsrichtung der zweiten Lageröffnung 68b erstrecken.Every second bearing opening 68b is out of round. It is delimited by outer second support surfaces 89 which extend perpendicularly or obliquely to a second circumferential direction of the second bearing opening 68b.

Jedes zweite Andrückelement 78b ist scheibenartig und hat umfangsseitig zweite Angriffsflächen 91. Jedes zweite Andrückelement 78b ist über den zweiten Lagerstift 85 an dem jeweiligen Seitentragkörper 54 um eine zweite Schwenkachse 79 schwenkbar gelagert. Jeder zweiter Lagerstift 85 ist exzentrisch zu dem zweiten Andrückelement 78b bzw. zu dessen Mittelachse 72b angeordnet. Jedes zweite Andrückelement 78b bildet einen zweiten Andrückexzenter.Every second pressing element 78b is disc-like and has circumferential second engagement surfaces 91. Every second pressing element 78b is over the second bearing pin 85 on the respective side support body 54 is pivotally mounted about a second pivot axis 79. Every second bearing pin 85 is arranged eccentrically to the second pressing element 78b or to its central axis 72b. Every second pressing element 78b forms a second pressing eccentric.

Jeweils ein zweites Schwenkmittel 80b in Form einer Druckfeder, insbesondere in Form einer Schraubendruckfeder, befindet sich zwischen einer zweiten Abstützflächen 89 und einer benachbarten zweiten Angriffsfläche 91.A second pivoting means 80b in the form of a compression spring, in particular in the form of a helical compression spring, is located between a second support surface 89 and an adjacent second engagement surface 91.

Wie Fig. 8 zeigt, ist die Leimdosierwalzen-Dichtkante 61 dichtend an der Leimdosierwalze 14 umfangsseitig angeordnet, sodass das erste Leimdamm-Dichtungselement 60b gegenüber der Leimdosierwalze 14 abdichtet. Die erste Schwenkachse 74 befindet sich seitlich in etwa auf Höhe der ersten Mittelachse 71b des ersten Andrückelements 73b. Das erste Leimdamm-Dichtungselement 60b befindet sich in einem neuen unverschlissenen Zustand.How Fig. 8 shows, the glue metering roller sealing edge 61 is sealingly arranged on the glue metering roller 14 on the circumferential side, so that the first glue dam sealing element 60b seals against the glue metering roller 14. The first pivot axis 74 is located laterally approximately at the level of the first central axis 71b of the first pressing element 73b. The first glue dam sealing element 60b is in a new unsealed state.

Gemäß Fig. 8 die Leimdosierwalzen-Abschlusskante 63 geringfügig beabstandet zu der Leimdosierwalze 14 angeordnet. Die Leimauftragswalzen-Dichtkante 64 ist dichtend an der Leimauftragswalze 15 umfangsseitig angeordnet, sodass die Leimauftragswalzen-Dichtkante 64 gegenüber der Leimauftragswalze 15 abdichtet. Die zweite Schwenkachse 79 befindet sich in einem unteren Bereich der zweiten Lageröffnung 68b.According to Fig. 8 the glue metering roller end edge 63 is arranged slightly spaced apart from the glue metering roller 14. The glue application roller sealing edge 64 is sealingly arranged on the glue application roller 15 on the circumferential side, so that the glue application roller sealing edge 64 seals against the glue application roller 15. The second pivot axis 79 is located in a lower region of the second bearing opening 68b.

Das erste Leimdamm-Dichtungselement 60b ist imstande, sich stets selbst an die Leimdosierwalze 14 anzupassen bzw. stets dicht an dieser umfangsseitig anzuliegen. Es ist imstande, eine Verstellung der Leimdosierwalze 14 selbständig mitzumachen.The first glue dam sealing element 60b is able to always adapt itself to the glue metering roller 14 or always close to the circumference thereof to rest. It is able to take part in an adjustment of the glue metering roller 14 independently.

Die ersten Schwenkmittel 75b üben auf das erste Andrückelement 73b ein erstes Schwenkmoment aus. Jedes erste Schwenkmittel 75b drückt das entsprechende zugeordnete erste Andrückelement 73b um die jeweilige erste Schwenkachse 74. Jedes erste Andrückelement 73b übt so eine resultierende erste Andrückkraft 76 auf das erste Leimdamm-Dichtungselement 60b aus, die genau auf die erste Drehachse 16 der Leimdosierwalze 14 gerichtet ist. Jedes erste Andrückelement 73b drückt so das erste Leimdamm-Dichtungselement 60b in Richtung auf die Leimdosierwalze 14, was zu einer gleichmäßigen dichten Anlage der Leimdosierwalzen-Dichtkante 61 an der Leimdosierwalze 14 führt (Fig. 9). Dies ist auch im verschlissenen Zustand des ersten Leimdamm-Dichtungselements 60b so.The first pivoting means 75b exert a first pivoting moment on the first pressing element 73b. Each first pivoting means 75b presses the corresponding associated first pressing element 73b about the respective first pivot axis 74. Each first pressing element 73b thus exerts a resulting first pressing force 76 on the first glue dam sealing element 60b, which is directed precisely at the first axis of rotation 16 of the glue metering roller 14 , Each first pressure element 73b thus presses the first glue dam sealing element 60b in the direction of the glue metering roller 14, which leads to a uniform, tight fit of the glue metering roller sealing edge 61 on the glue metering roller 14 ( Fig. 9 ). This is also the case when the first glue dam sealing element 60b is worn out.

Das zweite Leimdamm-Dichtungselement 62b ist imstande, sich stets selbst an die Leimauftragswalze 15 anzupassen bzw. stets dicht an dieser umfangsseitig anzuliegen.The second glue dam sealing element 62b is able to always adapt itself to the glue application roller 15 or to always lie tightly against the circumferential side thereof.

Die zweiten Schwenkmittel 80b üben auf das zweite Andrückelement 78b ein zweites Schwenkmoment aus. Jedes zweite Schwenkmittel 80b drückt das entsprechende zugeordnete zweite Andrückelement 78b um die jeweilige zweite Schwenkachse 79. Jedes zweite Andrückelement 78b übt so eine resultierende zweite Andrückkraft 81 auf das zweite Leimdamm-Dichtungselement 62b aus, die genau auf die zweite Drehachse 17 der Leimauftragswalze 15 gerichtet ist. Jedes zweite Andrückelement 78b drückt so das zweite Leimdamm-Dichtungselement 62b in Richtung auf die Leimauftragswalze 15, was zu einer gleichmäßigen dichten Anlage der Leimauftragswalzen-Dichtkante 64 an der Leimauftragswalze 15 führt (Fig. 9). Dies ist auch im verschlissenen Zustand des zweiten Leimdamm-Dichtungselements 62b so.The second pivoting means 80b exert a second pivoting moment on the second pressing element 78b. Every second pivoting means 80b presses the corresponding assigned second pressing element 78b about the respective second pivot axis 79. Each second pressing element 78b thus exerts a resulting second pressing force 81 on the second glue dam sealing element 62b, which is directed exactly at the second axis of rotation 17 of the glue application roller 15 , Every second pressure element 78b thus presses the second glue dam sealing element 62b in the direction of the glue application roller 15, which leads to a uniform, tight contact of the glue application roller sealing edge 64 with the glue application roller 15 ( Fig. 9 ). This is also the case when the second glue dam sealing element 62b is worn out.

Analoges gilt für den Einsatz der Leimdamm-Dichtungsanordnungen 19b in dem Leimwerk 28.The same applies to the use of the glue dam sealing arrangements 19b in the gluing unit 28.
