Die Längsschneide-Stationen 32 weisen jeweils drehantreibbare Messer 34 auf, die mit den Wellpappe-Bahnen 28, 29 zur Längsdurchtrennung derselben in Eingriff bringbar sind. Der genauere Aufbau der Rill-Station 31 und Längsschneide-Station 32 ist aus der DE 197 54 799 A (entspr. US 6,071,222) sowie der DE 101 31 833.2 bekannt, auf die hiermit für den Detailaufbau verwiesen wird.Behind the heating device 23 is a slitting / scoring device 30 arranged, which consists of two successively arranged creasing stations 31 and two successively arranged longitudinal cutting stations 32 consists. The creasing stations 31 each have pairs arranged one above the other Creasing tools 33, between which the corrugated webs 28th and 29 are performed on top of each other. The slitting stations 32 each have rotary drivable knife 34, which with the corrugated webs 28, 29 for longitudinal cutting of the same can be brought into engagement. The more detailed construction of the creasing station 31 and longitudinal cutting station 32 is from DE 197 54 799 A (corresponding to US 6,071,222) and the DE 101 31 833.2, to which reference is hereby made for the detailed construction becomes.

In Arbeits-Richtung 11 hinter der Einrichtung 30 ist eine Querschneide-Einrichtung 35 vorgesehen, die zwei drehantreibbare, übereinander angeordnete Walzen 36 aufweist, die jeweils einen sich radial nach außen erstreckenden, senkrecht zur Richtung 11 verlaufenden Messerbalken 37 tragen, welche zur Querdurchtrennung der Bahnen 28 und 29 zusammenwirken. Unmittelbar hinter der Querschneide-Einrichtung 35 ist ein um drehantreibbare Walzen 38 umgelenktes Förderband 39 vorgesehen. Hinter dem Förderband 39 ist eine Ablage 40 mit vertikal verlaufendem Anschlag 41 angeordnet, auf der Wellpappe-Bögen 42 einen Stapel 43 bildend gestapelt werden.In working direction 11 behind the device 30 is a cross-cutting device 35 provided, the two rotatably driven, one above the other Rollers 36 each having a radially outward extending, perpendicular to the direction 11 extending cutter bar 37th which, for the transverse transection of the webs 28 and 29 interact. Immediately behind the cross cutting device 35 is a deflected around rotatably drivable rollers 38 conveyor belt 39 is provided. Behind the conveyor belt 39 is a tray 40 with vertically running Stop 41 arranged on the corrugated sheets 42 a stack 43rd to be stacked.

Nachfolgend wird die Funktionsweise der Wellpappe-Anlage gemäß der ersten Ausführungsform beschrieben. In der Maschine 1 wird die einseitig kaschierte Wellpappe-Bahn 9 produziert und entlang der Arbeits-Richtung 11 der Vorheiz-Einrichtung 18 zugeführt. Gleichzeitig wird die Deckbahn 13 von der Abroll-Vorrichtung 12 abgerollt und ebenfalls in Richtung 11 der Vorheiz-Einrichtung 18 zugeführt. Gleiches geschieht mit der Maschine 14 und der Deckbahn 17. In der Vorheiz-Einrichtung 18 werden die vier Bahnen 9, 13, 15 und 17 vorgeheizt und anschließend die gewellten Unterseiten der Bahnen 9 und 15 im Leimwerk 20 beleimt. In der Heiz-Vorrichtung 23 wird die Deckbahn 13 an die Wellpappe-Bahn 9 gedrückt, so daß sich beide miteinander verbinden. Gleichzeitig wird die Deckbahn 17 gegen die Wellpappe-Bahn 15 gedrückt, so daß sich auch diese miteinander verbinden. Hierdurch entstehen die jeweils dreilagigen Wellpappe-Bahnen 28 und 29. Die Heiz-Vorrichtung 23 übernimmt gleichzeitig die Funktion, daß in dieser die Wellpappe-Bahnen 28 und 29 zusammengeführt werden und somit zwei in Arbeits-Richtung 11 bewegte Wellpappe-Bahnen aufeinander zu liegen kommen, ohne daß die Wellpappe-Bahnen 28 und 29 miteinander verbunden, insbesondere verklebt, sind. In den Stationen 31, 32 sowie der Einrichtung 35 erfolgt nun eine gleichzeitige Bearbeitung der aufeinanderliegenden Bahnen 28 und 29 durch die Rillwerkzeuge 33, die Messer 34 sowie die Messerbalken 37. Vorteilhaft hieran ist, daß mit einer Längsschneide-/Rill-Einrichtung 30 bzw. einer Querschneide-Einrichtung 35, die jeweils für die Bearbeitung einer Wellpappe-Bahn erforderlich sind, gleichzeitig zwei aufeinanderliegende Wellpappe-Bahnen 28, 29 bearbeitet werden können. Bei gleichbleibender Zahl von Bearbeitungs-Einrichtungen 30, 35 kann somit bei gleichbleibender Geschwindigkeit der Wellpappe-Bahn doppelt so viel Wellpappe bearbeitet werden. Hinter der Querschneide-Einrichtung 35 werden die Wellpappe-Bögen 42 geschuppt auf dem Förderband 39 abgelegt und gegen den Anschlag 41 auf der Ablage 40 gestapelt.Below is the operation of the corrugated plant according to the first embodiment described. In the machine 1, the one-sided laminated corrugated web 9 produced and along the working direction 11 of the preheating device 18 is supplied. At the same time, the cover sheet 13 unrolled from the roll-off device 12 and also in the direction of the eleventh the preheating device 18 is supplied. The same happens with the machine 14 and the cover sheet 17. In the preheater 18, the four Lanes 9, 13, 15 and 17 preheated and then the corrugated undersides the webs 9 and 15 glued in gluing unit 20. In the heating device 23, the cover sheet 13 is pressed against the corrugated web 9, so that they connect with each other. At the same time, the cover sheet 17 pressed against the corrugated web 15 so that they also together connect. This results in each of the three-ply corrugated webs 28 and 29. The heating device 23 takes over the same time Function that in this the corrugated webs 28 and 29 combined and thus two in the working direction 11 moving corrugated webs come to rest without the corrugated webs 28 and 29 connected to each other, in particular glued, are. In the stations 31, 32 and the device 35 is now a simultaneous processing the superposed tracks 28 and 29 by the scoring tools 33, the blades 34 and the cutterbars 37. Advantageously, that with a longitudinal cutting / creasing device 30 or a cross-cutting device 35, each for processing a corrugated web are required, simultaneously two superposed corrugated webs 28, 29 can be edited. With a constant number of processing facilities 30, 35 can thus at constant speed the corrugated web will be processed twice as much corrugated board. Behind the cross-cutting device 35, the corrugated sheets 42 scalped deposited on the conveyor belt 39 and against the stop 41 on the tray 40 stacked.

In der Heiz-Vorrichtung 23 kann auch eine andere Zahl von Wellpappe-Bahnen zusammengeführt werden. Es ist möglich, eine dritte, zur Maschine 1 identische Maschine sowie eine weitere, zur Abroll-Vorrichtung 12 identische Abroll-Vorrichtung vorzusehen, um in der Heiz-Vorrichtung 23 drei aufeinanderliegende, jedoch nicht miteinander verbundene Wellpappe-Bahnen zusammenzuführen. In diesem Fall würde der Ausstoß sogar um einen Faktor drei erhöht. Es ist auch möglich, anstelle der jeweils dreilagigen Wellpappe-Bahnen 28 und 29 nur die einseitig kaschierten Wellpappe-Bahnen 9 und 15 zusammenzuführen. In diesem Fall wären die Deckbahnen 13 und 17 mit den zugehörigen Abroll-Vorrichtungen 12 und 16 nicht erforderlich. Für das Zusammenführen der Wellpappe-Bahnen 9 und 15 wäre die Heiz-Vorrichtung 23 nicht erforderlich. Die Wellpappe-Bahnen 9 und 15 können durch einen Spalt zwischen zwei übereinander angeordneten Walzen geführt und damit zusammengeführt werden. Die Zusammenführ-Einrichtung wäre in diesem Fall sehr viel einfacher ausgebildet.In the heating device 23 may also be another number of corrugated webs be merged. It is possible, a third, to the machine 1 identical machine and another, the roll-off device 12th to provide identical unrolling device to in the heating device 23rd three superimposed but unconnected corrugated webs merge. In this case, the output would even be around a factor of three increased. It is also possible instead of each three-ply Corrugated webs 28 and 29 only the one-sided laminated corrugated webs 9 and 15 merge. In this case, the cover sheets would be 13 and 17 with the associated unwinding devices 12 and 16 not required. For merging the corrugated webs 9 and 15 if the heating device 23 were not required. The corrugated webs 9 and 15 can be arranged through a gap between two stacked Rolled out and brought together. The merging facility would be much easier in this case.

Für die Realisierung der in Fig. 1 dargestellten Anlage kann auf eine bestehende Anlage zur Herstellung siebenlagiger Wellpappe zurückgegriffen werden, wobei bei der siebenlagigen Wellpappe zwischen zwei glatten Papierbahnen immer eine Wellbahn angeordnet ist. Eine Anlage zur Herstellung siebenlagiger Wellpappe weist drei hintereinander angeordnete Maschinen zur Herstellung einseitig kaschierter Wellpappe auf, wobei die erste Maschine der Maschine 1 entspricht und die dritte Maschine der Maschine 14 entspricht. Die zweite Maschine wird so betrieben, daß die Wellbahn fehlt und lediglich die Deckbahn 13 abgewickelt wird.For the realization of the system shown in Fig. 1 can on an existing Plant used for the production of seven-ply corrugated board be with the seven-ply corrugated board between two smooth paper webs always a corrugated web is arranged. A plant for production seven-ply corrugated board has three machines arranged one behind the other for producing single-faced laminated corrugated cardboard, wherein the first machine corresponds to the machine 1 and the third machine to the machine 14 corresponds. The second machine is operated so that the corrugated web is missing and only the cover sheet 13 is handled.
