Definitions

  • the invention relates to a corrugated cardboard system according to the preamble of patent claim 1.

  • a format stacker is connected to the cross cutter and is connected to the cross cutter by a conveyor belt. The formats coming from the cross cutter arrive in a scaled arrangement on the conveyor belt, which works at a significantly lower feed rate than the cross cutter (for example one tenth the speed of the cross cutter).
  • the formats come out of the cross cutter at a relatively high speed and can therefore be damaged on their front edge.
  • the deflection angle is therefore kept very small, if possible, in order to avoid the described impairments of the corrugated cardboard.
  • a relatively small slope of the conveyor line is also necessary to counter the risk that the recorded formats slide down.
  • the desired long length cannot always be maintained for reasons of space. Therefore, a compromise between the length available for reasons of space and the critical deflection angle is usually to be chosen. For this reason, it can often not be avoided that the quality of the corrugated cardboard is deflected too strongly.
  • the invention is therefore based on the object of improving a corrugated cardboard system in such a way that impairment of the corrugated cardboard, in particular behind the cross cutter, is avoided by inadmissible deflection and its dimension is reduced in the working direction.
  • the gluing machine, short cross cutter, longitudinal creasing and cutting machine and cross cutter are arranged at an elevated level compared to the single-sided corrugated cardboard machine.
  • the roughly matching working level of the machines mentioned corresponds approximately to the infeed level of the format depositor.
  • the working level remains at essentially the same level throughout the entire further processing, which is at the level of the infeed plane of the format depositor. Undesirable deflections and deflections that affect the quality of the corrugated cardboard therefore do not take place.
  • the distance between the cross cutter and the format stacker is considerably reduced, which noticeably reduces the overall length of the system, which is naturally very large. Only a short transfer belt needs to be provided between the cross cutter and format stacker.
  • Disadvantages are not associated with the system according to the invention. Despite the increase in the level behind the one-sided machines, the available height of the production hall does not need to be increased compared to conventional systems. In addition, the room with control cabinets and other control devices can be used because of the higher-level units.

  • the lower preheating cylinder which is used to preheat a cover sheet, can be placed directly in front of the inlet of the gluing machine.

Description

Die Erfindung bezieht sich auf eine Wellpappenanlage nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a corrugated cardboard system according to the preamble of patent claim 1.

Wellpappenanlagen sind seit langem bekannt. Von der einseitigen Maschine wird die darin hergestellte einseitige Wellpappe zur Schlingenbildung auf eine Brücke gefördert, von der sie dann wieder auf das Niveau des Auftragwerks bzw. der Beklebemaschine herabgebracht wird. Von der Beklebemaschine gelangt die beidseitig mit Deckbahnen versehene Wellpappenbahn zu einem Kurzquerschneider, einer Längsschneid- und Rillmaschine und einem Querschneider. An den Querschneider schliesst sich ein Formatableger an, der über ein Förderband mit dem Querschneider verbunden ist. Die aus dem Querschneider kommenden Formate gelangen in geschuppter Anordnung auf das Förderband, das mit einer erheblich geringeren Vorschubgeschwindigkeit arbeitet als der Querschneider (zum Beispiel ein Zehntel der Geschwindigkeit des Querschneiders). Bei einer bekannten Wellpappenanlage nach der US-PS 2 039 750 sind alle genannten Aggregate auf einem Niveau angeordnet. Der Formatableger, in dem üblicherweise ein Formatstapel gebildet wird derart, dass die Formate von oben auf eine schrittweise nach unten bewegte Plattform gelegt werden, weist mithin einen oberhalb des Querschneiderauslaufs liegenden Einlauf auf. Die aus dem Querschneider kommenden Formate werden daher über eine Förderstrecke auf das Einlaufniveau des Formatablegers gebracht. Wird die Förderstrecke zu steil ausgelegt, besteht die Gefahr, dass die Wellpappe unzulässig abgelenkt wird. Neben den möglicherweise eintretenden Umbiegeeffekt am Ausgang des Querschneiders tritt ausserdem die Gefahr, dass die Formate mit ihrer vorderen Kante gegen das Förderband stossen. Die Formate kommen mit relativ hoher Geschwindigkeit aus dem Querschneider heraus und können daher an ihrer vorderen Kante beschädigt werden. Der Ablenkwinkel wird daher nach Möglichkeit sehr klein gehalten, um die beschriebenen Beeinträchtigungen der Wellpappe zu vermeiden. Dies führt zu einer entsprechend langen Förderstrecke, die mithin die Gesamtlänge einer Wellpappenanlage mitbestimmt. Im übrigen ist eine verhältnismässig geringe Steigung der Förderstrecke auch deshalb notwendig, um die Gefahr zu begegnen, dass die aufgenommenen Formate nach unten rutschen.' Die gewünschte grosse Länge kann jedoch aus Platzgründen nicht immer eingehalten werden. Daher ist zumeist ein Kompromiss zwischen der aus Platzgründen zur Verfügung stehenden Länge und dem kritischen Ablenkwinkel zu wählen. Aus diesem Grunde kann oft nicht vermieden werden, dass aufgrund einer zu starken Ablenkung der Wellpappe eine Beeinträchtigung ihrer Qualität stattfindet.Corrugated cardboard plants have been known for a long time. From the one-sided machine, the one-sided corrugated cardboard produced in it is conveyed to form a loop on a bridge, from which it is then brought back down to the level of the application unit or the gluing machine. The corrugated cardboard web, which is provided with cover sheets on both sides, comes from the pasting machine to a short cross cutter, a slitting and creasing machine and a cross cutter. A format stacker is connected to the cross cutter and is connected to the cross cutter by a conveyor belt. The formats coming from the cross cutter arrive in a scaled arrangement on the conveyor belt, which works at a significantly lower feed rate than the cross cutter (for example one tenth the speed of the cross cutter). In a known corrugated cardboard system according to US Pat. No. 2,039,750, all of the units mentioned are arranged on one level. The format depositor, in which a format stack is usually formed in such a way that the formats are placed from above on a platform which is moved downwards step by step, therefore has an inlet located above the cross cutter outlet. The formats coming from the cross cutter are therefore brought to the infeed level of the format stacker via a conveyor line. If the conveyor section is too steep, there is a risk that the corrugated cardboard will be deflected inadmissibly. In addition to the possibly occurring bending effect at the exit of the cross cutter, there is also the danger that the formats will hit the conveyor belt with their front edge. The formats come out of the cross cutter at a relatively high speed and can therefore be damaged on their front edge. The deflection angle is therefore kept very small, if possible, in order to avoid the described impairments of the corrugated cardboard. This leads to a correspondingly long conveyor line, which therefore also determines the total length of a corrugated cardboard system. In addition, a relatively small slope of the conveyor line is also necessary to counter the risk that the recorded formats slide down. ' However, the desired long length cannot always be maintained for reasons of space. Therefore, a compromise between the length available for reasons of space and the critical deflection angle is usually to be chosen. For this reason, it can often not be avoided that the quality of the corrugated cardboard is deflected too strongly.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Wellpappenanlage so zu verbessern, dass Beeinträchtigungen der Wellpappe, insbesondere hinter dem Querschneider, durch unzulässiges Ablenken vermieden und ihre Abmessung in Arbeitsrichtung verringert wird.The invention is therefore based on the object of improving a corrugated cardboard system in such a way that impairment of the corrugated cardboard, in particular behind the cross cutter, is avoided by inadmissible deflection and its dimension is reduced in the working direction.

Diese Aufgabe wird durch die Merkmale des Kennzeichnungsteils des Patentanspruchs 1 gelöst.This object is achieved by the features of the characterizing part of patent claim 1.

Bei der erfindungsgemässen Wellpappenanlage sind Beklebemaschine, Kurzquerschneider, Längsrill- und Schneidemaschine und Querschneider gegenüber der einseitigen Wellpappenmaschine auf einem erhöhten Niveau angeordnet. Die annähernd übereinstimmende Arbeitsebene der erwähnten Maschinen stimmt annähernd mit der Einlaufebene des Formatablegers überein.In the case of the corrugated cardboard system according to the invention, the gluing machine, short cross cutter, longitudinal creasing and cutting machine and cross cutter are arranged at an elevated level compared to the single-sided corrugated cardboard machine. The roughly matching working level of the machines mentioned corresponds approximately to the infeed level of the format depositor.

Nachdem bei der erfindungsgemässen Wellpappenanlage die einseitige Wellpappe von der einseitigen Maschine zur Schlingenbildung auf die Brücke gefördert worden ist, bleibt das Arbeitsniveau während der gesamten weiteren Bearbeitung auf im wesentlichen der gleichen Höhe, das in der Höhe der Einlaufebene des Formatablegers liegt. Unerwünschte Ab- und Umlenkungen, welche die Qualität der Wellpappe beeinträchtigen, finden daher nicht statt. Ausserdem wird der Abstand zwischen dem Querschneider und dem Formatableger erheblich reduziert, wodurch die Gesamtlänge der Anlage, die naturgemäss sehr gross ist, merklich verringert wird. Zwischen Querschneider und Formatableger braucht lediglich ein kurzes Überführungsband vorgesehen zu werden.After the one-sided corrugated cardboard has been conveyed from the one-sided machine to form a loop onto the bridge in the corrugated cardboard system according to the invention, the working level remains at essentially the same level throughout the entire further processing, which is at the level of the infeed plane of the format depositor. Undesirable deflections and deflections that affect the quality of the corrugated cardboard therefore do not take place. In addition, the distance between the cross cutter and the format stacker is considerably reduced, which noticeably reduces the overall length of the system, which is naturally very large. Only a short transfer belt needs to be provided between the cross cutter and format stacker.

Nachteile sind mit der erfindungsgemässen Anlage nicht verbunden. Trotz der Anhebung des Niveaus hinter den einseitigen Maschinen braucht die zur Verfügung stehende Höhe der Fertigungshalle gegenüber herkömmlichen Anlagen nicht vergrössert zu werden. Im übrigen kann wegen der erhöht angeordneten Aggregate der Raum mit Schaltschränken und anderen Steuerungsgeräten ausgenutzt werden.Disadvantages are not associated with the system according to the invention. Despite the increase in the level behind the one-sided machines, the available height of the production hall does not need to be increased compared to conventional systems. In addition, the room with control cabinets and other control devices can be used because of the higher-level units.

Nach einer Ausgestaltung der Erfindung ist vorgesehen, dass auch Vorheizer und Auftragswerk auf dem erhöhten Niveau angeordnet sind. Auf diese Weise kann auch der untere Vorheizzylinder, der zur Vorheizung einer Deckbahn dient, direkt vor den Einlauf der Beklebemaschine gesetzt werden. Dadurch wird der Wärmeverlust herkömmlicher Anlagen vermieden, welcher durch den relativ langen Weg zwischen Vorheizzylinder und Beklebemaschine zurückgelegt werden musste.According to an embodiment of the invention, it is provided that the preheater and applicator are also arranged at the elevated level. In this way, the lower preheating cylinder, which is used to preheat a cover sheet, can be placed directly in front of the inlet of the gluing machine. This avoids the heat loss of conventional systems, which had to be covered due to the relatively long way between the preheating cylinder and the gluing machine.

Es gibt verschiedene konstruktive Möglichkeiten zur erfindungsgemässen Anordnung der Wellpappenanlage. Eine Ausgestaltung der Erfindung sieht vor, dass die auf erhöhtem Niveau befindlichen Maschinen auf der Plattform eines Podestes angeordnet sind. Das Podest, auf dem die Maschinen stehen, kann zweckmässigerweise als Verlängerung der ohnehin vorhandenen Brücke über den Wellpappenherstellungsmaschinen angeordnet sein, so dass von vorne bis hinten auf einer Ebene gearbeitet werden kann.There are various design options for the arrangement of the corrugated cardboard system according to the invention. One embodiment of the invention provides that the machines located at an elevated level are arranged on the platform of a platform. The platform on which the machines stand can be expediently arranged as an extension of the bridge that is already present above the corrugated cardboard production machines, so that work can be carried out from front to back on one level.

Alternativ kann nach einer anderen Ausgestaltung der Erfindung vorgesehen sein, dass die auf erhöhtem Niveau befindlichen Maschinen auf einer Geschossdecke angeordnet sind, während die vorgeschalteten Maschinen auf dem Boden des Raumes unterhalb der Geschossdecke angeordnet sind. Dies hat den erheblichen weiteren Vorteil, dass die heissen und sehr lauten einseitigen Wellpappenmaschinen z.B. in einem Keller angeordnet sind. Auch der Transport der Papierrollen, der viel Platz erfordert, erfolgt im Keller. In der oberen Etage findet die gesamte Maschinenbedienung auf einer Arbeitsebene statt. Der Abtransport der Pappen erfolgt wiederum im Keller.Alternatively, it can be provided according to another embodiment of the invention that the machines located at an elevated level are arranged on a floor ceiling, while the upstream machines are arranged on the floor of the room below the floor ceiling. This has the considerable further advantage that the hot and very loud single-sided corrugated cardboard machines are arranged, for example, in a basement. The paper rolls, which take up a lot of space, are also transported in the basement. The entire machine operation takes place on one working level on the upper floor. The cardboard is then removed in the basement.

Nach einer weiteren Ausgestaltung der Erfindung kann eine Wellpappenanlage noch erheblich kürzer bauen. Sie besteht erfindungsgemäss darin, dass die Vorschubrichtung der einseitig gewellten Bahn nach dem Verlassen der einseitigen Wellpappenmaschine entgegengesetzt zu der in der Beklebemaschine ist und dazwischen eine annähernd um 180° verlaufende Bahnumlenkung erfolgt.According to a further embodiment of the invention, a corrugated cardboard system can be built considerably shorter. According to the invention, it consists in that the direction of advance of the web that is corrugated on one side after leaving the one-sided corrugated cardboard machine is opposite to that in the gluing machine and there is an approximately 180 ° web deflection between them.

Bei der erfindungsgemässen Anlage können die auf unterschiedlichem Niveau angeordneten Maschinen und Aggregate übereinander angeordnet werden, so dass sich die Gesamtlänge der Wellpappenanlage ganz erheblich verringert. Die einseitigen Maschinen befinden sich im unteren Stockwerk der Anlage. Vorzugsweise befindet sich auch die Brücke für die einseitige Bahn oberhalb der Herstellungsmaschine im unteren Stockwerk.In the system according to the invention, the machines and units arranged at different levels can be arranged one above the other, so that the overall length of the corrugated cardboard system is reduced considerably. The one-sided machines are located on the lower floor of the plant. The bridge for the one-sided web is preferably also located above the manufacturing machine on the lower floor.

Die auf erhöhtem Niveau befindlichen Maschinen können auf einer Plattform eines Podestes angeordnet sein. Die Herstellungsmaschinen, die Abrollung und die Brücke für die einseitige Bahn befinden sich dabei unterhalb des Podestes.The machines located at a higher level can be arranged on a platform of a platform. The manufacturing machines, the unwinding and the bridge for the one-sided web are located below the platform.

Eine andere Alternative besteht erfindungsgemäss darin, dass die auf erhöhtem Niveau befindlichen Maschinen auf einer Geschossdecke angeordnet sind, während die vorgeschalteten Maschinen auf dem Boden eines Raumes unterhalb der Geschossdecke angeordnet sind und die umgelenkten Bahnen durch eine Öffnung in der Geschossdecke hindurchgeführt sind. Die heissen und lauten einseitigen Wellpappenmaschinen können z.B. in einem Keller angeordnet sein. Auch der Transport der Papierrollen, der viel Platz erfordert, kann im Keller erfolgen.Another alternative according to the invention is that the machines located at an elevated level are arranged on a floor ceiling, while the upstream machines are arranged on the floor of a room below the floor ceiling and the deflected tracks are led through an opening in the floor ceiling. The hot and loud single-sided corrugated cardboard machines can e.g. be arranged in a basement. The paper rolls, which require a lot of space, can also be transported in the basement.

In der oberen Etage findet die gesamte Maschinenbedienung auf einer Arbeitsebene statt. Der Abtransport der Pappen erfolgt wiederum im Keller.The entire machine operation takes place on one working level on the upper floor. The cardboard is then removed in the basement.

Für die Zuführung der zweiten Deckbahn sieht eine weitere Ausgestaltung der Erfindung vor, dass die Abrollung für die zweite Deckbahn seitlich angeordnet ist mit einer Vorschubrichtung annähernd senkrecht zur ersten und zweiten Vorschubrichtung und im Umlenkbereich einer annähernd 90°-Umlenkung der zweiten Deckbahn erfolgt. Die zweite Deckbahn wird daher so zugeführt, dass die einseitige Bahn um diese herum umgelenkt wird.For feeding the second cover sheet, a further embodiment of the invention provides that the unwinding for the second cover sheet is arranged laterally with a feed direction approximately perpendicular to the first and second feed directions and in the deflection area of an approximately 90 ° deflection of the second cover sheet. The second cover sheet is therefore fed in such a way that the one-sided sheet is deflected around it.

Drei Ausführungsbeispiele der Erfindung werden nachfolgend anhand von Zeichnungen näher erläutert.

  • Fig. 1 zeigt in Seitenansicht äusserst schematisch eine erste Ausführungsform der erfindungsgemässen Wellpappenanlage.
  • Fig. 2 zeigt in äusserst schematischer Form eine zweite Ausführungsform der erfindungsgemässen Wellpappenanlage.
  • Fig. 3 zeigt in Seitenansicht äusserst schematisch eine Wellpappenanlage nach der Erfindung.
  • Fig. 4 zeigt die Draufsicht auf die Umlenkung der zweiten Deckbahn der Anlage nach Fig. 2.
Three exemplary embodiments of the invention are explained in more detail below with reference to drawings.
  • 1 shows, in side view, very schematically a first embodiment of the corrugated cardboard plant according to the invention.
  • 2 shows, in an extremely schematic form, a second embodiment of the corrugated cardboard plant according to the invention.
  • Fig. 3 shows an extremely schematic side view of a corrugated cardboard system according to the invention.
  • FIG. 4 shows the top view of the deflection of the second cover sheet of the system according to FIG. 2.

Eine erste einseitige Wellpappenmaschine 10 wird von zwei jeweils benachbarten, zwei Papierrollen aufnehmenden Abrollungen 11 und 12 versorgt. Die einseitige Wellpappenbahn wird auf eine Brücke 13 hochbefördert, die über Stützen 14 am Boden 15 abgestützt ist. Eine zweite einseitige Wellpappenmaschine 16 wird wiederum von zwei Abrollungen 17,18 versorgt. Die einseitige Wellpappe wird wiederum zur Brücke 13 hochbefördert. Ein Podest 19 enthält eine über Stützen 20 am Boden 15 abgestützte Plattform 21. Auf der Plattform angeordnet sind unmittelbar benachbart ein Vorheizer 22, ein Auftragswerk 23, eine Beklebemaschine 24, ein Kurzquerschneider 25, eine Rill- und Schneidmaschine 26, ein Querschneider 27 und ein Formatableger 28.A first single-sided corrugated cardboard machine 10 is supplied by two adjacent unwinds 11 and 12, each holding two paper rolls. The one-sided corrugated cardboard web is conveyed up onto a bridge 13, which is supported by supports 14 on the floor 15. A second one-sided corrugated cardboard machine 16 is in turn supplied by two unwinds 17, 18. The one-sided corrugated cardboard is in turn conveyed up to the bridge 13. A platform 19 contains a platform 21 supported by supports 20 on the floor 15. A preheater 22, an application unit 23, a gluing machine 24, a short cross cutter 25, a creasing and cutting machine 26, a cross cutter 27 and a are arranged directly adjacent to the platform Format depositor 28.

Man erkennt, dass das Arbeitsniveau der Maschinen 22 bis 28 annähernd in gleicher Ebene liegt, welche wiederum in annähernd gleicher Höhe mit der Brücke 13 liegt. Umlenkungen der Bahnen bzw. der Wellpappe sind daher nicht notwendig. Der Abstand zwischen Querschneider 27 und Formatableger ist äusserst gering. Im Formatableger 28 sind zwei Formatstapel 29, 30 angedeutet.It can be seen that the working level of the machines 22 to 28 lies approximately in the same plane, which in turn lies at approximately the same height with the bridge 13. Deflections of the webs or corrugated cardboard are therefore not necessary. The distance between cross cutter 27 and format depositor is extremely small. Two format stacks 29, 30 are indicated in the format depositor 28.

Man erkennt ferner, dass der von der Abrollung 31 versorgte Vorheizzylinder 32 unmittelbar vor der Beklebemaschine 24 angeordnet ist, so dass auch bezüglich der zweiten Deckbahn ein kurzer Weg zwischen Vorheizung und Beklebemaschine liegt.It can also be seen that the preheating cylinder 32 supplied by the unwind 31 is arranged directly in front of the gluing machine 24, so that there is also a short path between the preheating and gluing machine with respect to the second cover sheet.

In Fig. 2 sind die einzelnen Maschinen der gezeigten Anlage, soweit sie mit denen nach Fig. 1 übereinstimmen, mit gleichen Bezugszeichen versehen. Der Unterschied zur Anlage nach Fig. 1 besteht darin, dass die Maschinen 22 bis 27 auf einer Geschossdecke 34 angeordnet sind, wobei sich die «Brücke» 13 ebenfalls auf der Geschossdecke 34 befindet. Die Maschinen 11 bis 18 und 31 sind hingegen auf dem Boden 35 eines Kellers 33 angeordnet. Der Formatableger 28 erstreckt sich vom Boden 35 durch die Decke 34 hindurch.In Fig. 2, the individual machines of the system shown, insofar as they match those of Fig. 1, are given the same reference numerals. The difference from the system according to FIG. 1 is that the machines 22 to 27 are arranged on a floor 34, the “bridge” 13 also being located on the floor 34. The machines 11 to 18 and 31, however, are arranged on the floor 35 of a basement 33. The format depositor 28 extends from the floor 35 through the ceiling 34.

Bei der gezeigten Anlage nach Fig. 2 befindet sich die gesamte Maschinenbedienung auf einer Arbeitsebene, nämlich auf dem Geschossdeck 34, während der Transport der Papierrollen und der Abtransport der Pappen aus dem Formatableger 28 im Keller erfolgt. Die heissen und lauten einseitigen Maschinen 10 und 16 können daher die Arbeitsbedingungen auf dem Geschossdeck 34 nicht oder nur unwesentlich beeinträchtigen.In the system shown in FIG. 2, the entire machine operation is on one working level, namely on the floor deck 34, while the transport of the paper rolls and the removal of the cardboard from the format stacker 28 takes place in the basement. The hot and loud one-sided machines 10 and 16 can therefore not or only insignificantly impair the working conditions on the floor deck 34.

Nachfolgend wird auf die Figuren 3 und 4 eingegangen. Soweit gleiche Teile wie in Fig. 1 oder 2 vorkommen, werden gleiche Bezugszeichen verwendet.3 and 4 are discussed below. As far as the same parts as in Fig. 1 or 2 occur, the same reference numerals are used.

Eine einseitige Wellpappenmaschine 10 wird von jeweils zwei benachbarten, zwei Papierrollen aufnehmenden Abrollungen 11 und 12 versorgt. Entsprechend sind der einseitigen Maschine 10 Vorheizer 40,41 zugeordnet. Eine erste Brücke 42 nimmt die einseitige Bahn in bekannter gefalteter Weise auf. Eine zweite darüber angeordnete Brücke 63 nimmt eine zweite einseitige Bahn 49 auf, die von einem weiteren Satz von Abrollungen und einer einseitigen Maschine hergestellt wurde. Die erste einseitige Bahn 43 wird über Umlenkrollen 44,45 und 46 um etwa 180° umgelenkt. Zu Umlenkzwecken ist die Rolle 44 tiefer als die Brücke 42 angeordnet. Die Rolle 45 befindet sich auf annähernd gleichem Niveau wie die Rolle 44, während die Rolle 46 sich oberhalb der Rolle 45 befindet. Über eine Vorheizwalze 47 erfolgt eine Umlenkung nach oben in Richtung eines oberen Auftragswerks 48. Die zweite einseitige Bahn 49 wird mit entsprechenden Umlenkrollen 50, 51 und 52 in ähnlicher Weise umgelenkt. Eine Vorheizwalze 53 lenkt die zweite Bahn 49 in Richtung eines unterhalb des oberen Auftragswerks 48 angeordneten Auftragswerks 54. Die Auftragswerke 48, 54 sind auf einer Plattform oder Geschossdecke 34 übereinander angeordnet, auf der auch eine Beklebemaschine 24 bekannter Bauart angeordnet ist. An die Beklebemaschine schliessen sich bekannte Maschinen, wie Kurzquerschneider, Rill- und Schneidmaschine, Querschneider und Formatableger an, die auf annähernd gleichem Niveau angeordnet, jedoch nicht dargestellt sind.A single-sided corrugated cardboard machine 10 is supplied by two adjacent unwinds 11 and 12, each holding two paper rolls. Correspondingly, the preheaters 40, 41 are assigned to the one-sided machine. A first bridge 42 receives the one-sided web in a known folded manner. A second bridge 63 located above receives a second one-sided web 49 made by another set of unwinds and a one-sided machine. The first one-sided web 43 is deflected by deflecting rollers 44, 45 and 46 by approximately 180 °. For deflection purposes, the roller 44 is arranged lower than the bridge 42. The roller 45 is at approximately the same level as the roller 44, while the roller 46 is above the roller 45. A preheating roller 47 deflects upwards in the direction of an upper applicator 48. The second one-sided web 49 is deflected in a similar manner with corresponding deflecting rollers 50, 51 and 52. A preheating roller 53 directs the second web 49 in the direction of an application unit 54 arranged below the upper application unit 48. The application units 48, 54 are arranged one above the other on a platform or floor 34 on which a gluing machine 24 of a known type is also arranged. Known machines such as short cross cutters, creasing and cutting machines, cross cutters and format depositors are connected to the gluing machine, which are arranged at approximately the same level, but are not shown.

Die Geschossdecke 34 besitzt eine Öffnung 55 in der die Umlenkung der Bahnen 43 und 49 in Form einer Schleife stattfindet. Es versteht sich, dass die Geschossdecke 34 auch die Plattform eines Podestes sein kann, wobei dann die beschriebenen Umlenkungen sowie die Vorheizer 47, 53 am Rand der Plattform angeordnet sind.The floor ceiling 34 has an opening 55 in which the deflection of the tracks 43 and 49 takes place in the form of a loop. It goes without saying that the floor ceiling 34 can also be the platform of a platform, the deflections described and the preheaters 47, 53 then being arranged on the edge of the platform.

Eine zweite Deckbahn 56 wird seitlich so zugeführt, dass sie senkrecht zur Umlenkebene der Bahnen 43, 49 in die durch diese gebildete Schleife eingeleitet wird, wie bei 57 dargestellt. Mittels zwei übereinander angeordneten Umlenkrollen 58, 59 erfolgt eine Umlenkung der zweiten Deckbahn 56 um annähernd 90°, wobei die Umlenkrollen 58, 59 mit ihrer Drehachse einen Winkel von 45° zur Vorschubrichtung der Deckbahn 56 einschliesst. In Fig. 4 ist die seitlich angeordnete Papierrolle 60 dargestellt, von der die zweite Deckbahn 56 abgewickelt wird. Es versteht sich, dass die Papierrolle 60 bzw. das Gestell für die Abrollung auf dem gleichen Niveau wie die Abrollungen 11 und 12 angeordnet sein kann. Dies erfordert dann noch weitere Umlenkrollen als in den Figuren 3 und 4 dargestellt.A second cover sheet 56 is fed laterally in such a way that it is introduced perpendicularly to the deflection plane of the sheets 43, 49 into the loop formed thereby, as shown at 57. By means of two deflecting rollers 58, 59 arranged one above the other, the second cover sheet 56 is deflected by approximately 90 °, the deflecting rollers 58, 59 including an angle of 45 ° with the direction of advance of the cover sheet 56 with its axis of rotation. 4 shows the laterally arranged paper roll 60 from which the second cover sheet 56 is unwound. It goes without saying that the paper roll 60 or the frame for the unwinding can be arranged on the same level as the unrolling 11 and 12. This then requires further deflection rollers than shown in FIGS. 3 and 4.

Die Umlenkung der zweiten Deckbahn 56 durch die Umlenkrollen 58, 59 erfolgt bis annähernd auf das Niveau einer Vorheizwalze 61, die hinter den Auftragswerken 48, 54 kurz vor der Beklebemaschine 24 angeordnet ist. Im übrigen können eine oder beide Umlenkwalzen 58, 59 als Vorheizer verwendet werden.The deflection of the second cover sheet 56 by the deflection rollers 58, 59 takes place up to approximately the level of a preheating roller 61, which is arranged behind the application units 48, 54 just before the gluing machine 24. Otherwise, one or both deflecting rollers 58, 59 can be used as preheaters.
