Definitions
- the invention relates to a method for attaching a front cover made of corrugated cardboard on end faces of a web roll. Furthermore, the invention relates to a roll packaging machine for the application of such a method.
- end covers In the paper industry, end faces of the paper or board web rolls are protected by so-called end covers. These end covers are usually made of corrugated cardboard, ie at least one corrugated paper web, which is provided with at least one cover layer. Corrugated board has the advantage that it is relatively inexpensive to produce, has only a small mass and yet is sufficiently resistant.
- the two end faces of the material web roll are first covered with an inner end cover. Subsequently, the web roll is wrapped with wrapping paper, wherein the ends of the wrapping paper are folded at the end faces. Subsequently, the end faces are glued to an outer end cover, which fixes the fold.
- the attachment of the end cover is largely automatic, the end covers are moved by means of suction gripping arms. The end covers are stored in stacks of approx. 200 to 300 lids.
- end covers In order for the end covers can be reasonably mounted on the end faces, it is necessary that the end covers are relatively stiff. A flexurally soft corrugated board is accordingly unfavorable for the production of end caps.
- the end covers are therefore made of corrugated cardboard with at least two cover layers. This will be the front cover tailored at the corrugated cardboard manufacturer and combined into stacks.
- the invention is based on the object at least partially to integrate the end cap production in the value creation process of the paper producer.
- corrugated board can be obtained at a lower cost and on the other hand, stockpiling is simplified. From a supply roll so may also front cover different sizes are made so that they can be easily adapted to different web roll diameter.
- the provision of corrugated cardboard as a roll product also has the advantage that it can be relatively easily transported and stored.
- the corrugated cardboard preferably has a continuous first cover layer, at least one intermediate layer and at least one flaky second cover layer on the supply roll.
- a corrugated cardboard with a continuous first cover layer, with a corrugated intermediate layer is also referred to as single-sided corrugated board.
- a single-faced corrugated board is relatively flexible and can be used well as a roll product.
- the corrugated board is correspondingly rigid in this direction, while it can be easily rolled up in the other direction.
- end covers it is usually sufficient that the end covers are rigid in one direction. The stiffening of the corrugated board takes place, so to speak, by the flat spreading of the corrugated cardboard after removal from the supply roll.
- the individual scales of the scale-shaped cover layer have similar or different shapes, which can positively and / or non-positively connect with each other.
- the scales have simple rectangular shapes, the edges of which can come into operative connection shock-to-joint and so can set effective bending limits in one direction.
- the individual scales have puzzle-like shapes.
- adjacent scales may have the same or different shapes. In such puzzle-like scales parts of the one scale can engage in areas of the adjacent scale. Here can then form a positive and non-positive connection arise, which can be solved, for example, after overcoming a defined force range again.
- adjacent scales of the second cover layer are joined together during stiffening. This achieves a simple way that the corrugated cardboard is rigid in both directions.
- the adjacent scales are glued together, sewn or embossed.
- embossing which is also referred to as crimping, has the advantage that no foreign substances are introduced into the corrugated board. Since the scales are usually made of paper, no longer needed end faces and cut remnants can be easily recycled. For this purpose, the end faces and cut remnants that are no longer required can also be returned directly to the pulp of a paper machine.
- the corrugated cardboard on the supply roll only on a first cover layer and at least one corrugated intermediate layer, wherein the corrugated cardboard is provided during stiffening with at least a second cover layer.
- a corrugated board with only one cover layer and one or two intermediate layers is relatively flexible and can be easily stored as a roll. By attaching the second cover layer after removing the corrugated cardboard from the supply roll, the corrugated cardboard is rigid in both directions and can be further processed so well to end covers.
- the second cover layer is supplied from a supply roll.
- the second cover layer which is usually off Paper or cardboard is formed, so is also available as a roll. If the first cover layer has two corrugated intermediate layers, two further cover layers are correspondingly supplied.
- the storage of the second cover layers as a supply roll is relatively space-saving and allows easy feeding.
- the second cover layer is glued, sewn or embossed with the intermediate layer and / or the first cover layer.
- the intermediate layer can be coated, for example, with a starch glue, wherein the second cover layer is guided by means of a roller to the intermediate layer.
- embossing which is also called crimping
- the second cover layer is connected to the intermediate layer and / or the first cover layer by means of embossing rollers or embossing wheels.
- the end covers are cut out of the corrugated cardboard with a laser, wherein preferably the second cover layer or the adjacent flakes are also hot-bonded with the laser.
- a laser that is used to cut the front cover, so also a hot bonding of the second cover layer takes place with the liner. If necessary, only one focal length of the laser has to be adapted. The stiffening of the corrugated board and the production of the end cover can then be done in a single processing station and is therefore fast and inexpensive.
- a roll packaging machine of the type mentioned above in that it has an unwinding device and a stiffening device, wherein in the unwinding corrugated cardboard is removable from a supply roll and the withdrawn corrugated cardboard is stiffened in the stiffening device.
- the corrugated board can therefore be stored as a roll on a supply roll.
- the stiffening of the corrugated board takes place only in the stiffening device of the roll packaging machine, ie only when a stiff corrugated cardboard is required.
- the soft, corrugated cardboard that was previously soft can easily be stored.
- the roll packaging machine has a cutting device.
- the corrugated cardboard has a continuous first cover layer, at least one corrugated intermediate layer and at least one scale-like cover layer. Adjacent scales of the scale-shaped cover layer can then be connected to one another in the stiffening device. The stiffening of the corrugated board is then possible without great effort in the roll packaging machine.
- the roll packaging machine has at least one feed device for a cover layer, which can be connected to the corrugated cardboard in the stiffening device. This is another easy way to stiffen a corrugated board in which a two-sided corrugated board is produced from a single-sided corrugated board.
- a corrugated cardboard 1 is shown, which is withdrawn as a roll from a supply roll 2 and just after spreading the supply roll 2 is spread.
- the corrugated cardboard 1 has a first cover layer 3, with which a corrugated intermediate layer 4 is glued.
- the splices are shown as dots.
- the intermediate layer 4 is connected to a scale-shaped second cover layer 5, wherein the intermediate layer 4 and the cover layer 5 are glued together in this example.
- the second cover layer 5 in this case has a plurality of scales 6, wherein each wave crest of the intermediate layer 4 is associated with a scale 6.
- Adjacent scales 6 overlap each other like a roof tile, wherein a deflection of the corrugated cardboard 1 about the first cover layer 3 is possible and is prevented in the opposite direction by the scales 6 by one end of the scales against the junction of the adjacent scale with the intermediate layer 4 abuts.
- a corrugated cardboard 1 is shown, which is rigid in one direction.
- a second embodiment of the corrugated cardboard 1 is shown, in the same elements with the same reference numerals as in Fig. 1 are provided.
- the corrugated cardboard 1 is mounted as a single-sided corrugated cardboard on the supply roll 2 and is deducted from this.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Anbringen eines Stirndeckels aus Wellpappe an Stirnseiten einer Materialbahnrolle. Ferner betrifft die Erfindung eine Rollenpackmaschine zur Anwendung eines derartigen Verfahrens.The invention relates to a method for attaching a front cover made of corrugated cardboard on end faces of a web roll. Furthermore, the invention relates to a roll packaging machine for the application of such a method.
In der Papierindustrie werden Stirnseiten der Papier- oder Kartonbahnrollen durch sogenannte Stirndeckel geschützt. Diese Stirndeckel sind in der Regel aus Wellpappe hergestellt, also aus mindestens einer gewellten Papierbahn, die mit mindestens einer Deckellage versehen ist. Wellpappe hat den Vorteil, dass sie relativ kostengünstig herstellbar ist, nur eine geringe Masse aufweist und dennoch ausreichend widerstandsfähig ist.In the paper industry, end faces of the paper or board web rolls are protected by so-called end covers. These end covers are usually made of corrugated cardboard, ie at least one corrugated paper web, which is provided with at least one cover layer. Corrugated board has the advantage that it is relatively inexpensive to produce, has only a small mass and yet is sufficiently resistant.
Bei der Rollenverpackung werden zunächst die beiden Stirnseiten der Materialbahnrolle mit jeweils einem inneren Stirndeckel abgedeckt. Anschließend wird die Materialbahnrolle mit Packpapier umhüllt, wobei die Enden des Packpapiers an den Stirnseiten eingefaltet werden. Anschließend werden die Stirnseiten mit einem äußeren Stirndeckel verklebt, der die Faltung fixiert. Das Anbringen der Stirndeckel erfolgt dabei weitgehend automatisch, wobei die Stirndeckel mit Hilfe von saugerbestückten Greifarmen bewegt werden. Die Stirndeckel werden dabei in Stapeln mit ca. 200 bis 300 Deckeln bevorratet.In the roll wrapping, the two end faces of the material web roll are first covered with an inner end cover. Subsequently, the web roll is wrapped with wrapping paper, wherein the ends of the wrapping paper are folded at the end faces. Subsequently, the end faces are glued to an outer end cover, which fixes the fold. The attachment of the end cover is largely automatic, the end covers are moved by means of suction gripping arms. The end covers are stored in stacks of approx. 200 to 300 lids.
Damit die Stirndeckel vernünftig an den Stirnseiten angebracht werden können, ist es erforderlich, dass die Stirndeckel relativ steif ausgebildet sind. Eine biegeweiche Wellpappe ist für die Herstellung von Stirndeckeln dementsprechend ungünstig. Die Stirndeckel werden daher aus Wellpappe mit mindestens zwei Deckellagen hergestellt. Dabei werden die Stirndeckel beim Wellpappenhersteller zugeschnitten und zu Stapeln zusammengefasst.In order for the end covers can be reasonably mounted on the end faces, it is necessary that the end covers are relatively stiff. A flexurally soft corrugated board is accordingly unfavorable for the production of end caps. The end covers are therefore made of corrugated cardboard with at least two cover layers. This will be the front cover tailored at the corrugated cardboard manufacturer and combined into stacks.
Der Erfindung liegt nun die Aufgabe zugrunde, die Stirndeckelherstellung zumindest teilweise in den Wertschöpfungsprozess des Papierproduzenten zu integrieren.The invention is based on the object at least partially to integrate the end cap production in the value creation process of the paper producer.
Bei einem Verfahren der eingangs genannten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass das Verfahren die folgenden aufeinanderfolgenden Schritte umfasst:
- a) Die Wellpappe wird von einer Vorratsrolle abgezogen,
- b) die Wellpappe wird versteift,
- c) aus der Wellpappe werden die Stirndeckel erzeugt und
- d) die Stirndeckel werden an den Stirnseiten der Materialbahnrolle angebracht.
- a) the corrugated board is withdrawn from a supply roll,
- b) the corrugated cardboard is stiffened,
- c) from the corrugated cardboard end caps are generated and
- d) the end covers are attached to the end faces of the web roll.
Es ist dadurch möglich, die Stirndeckel erst unmittelbar vor dem Aufbringen auf den Stirnseiten der Materialbahn fertig zu stellen. So können sie bis dahin in biegeweicher Form auf einer Vorratsrolle gelagert werden. Dadurch kann die Wellpappe zum einen kostengünstiger bezogen werden und zum anderen wird die Vorratshaltung vereinfacht. Aus einer Vorratsrolle können so möglicherweise auch Stirndeckel unterschiedlicher Größe hergestellt werden, so dass diese leicht an unterschiedliche Materialbahnrollendurchmesser angepasst werden können. Die Bereitstellung der Wellpappe als Rollenware hat darüber hinaus den Vorteil, dass sie relativ einfach transportiert und gelagert werden kann.It is thereby possible to finish the end cover only immediately before applying to the end faces of the material web. So they can be stored until then in flexible shape on a supply roll. As a result, the corrugated board can be obtained at a lower cost and on the other hand, stockpiling is simplified. From a supply roll so may also front cover different sizes are made so that they can be easily adapted to different web roll diameter. The provision of corrugated cardboard as a roll product also has the advantage that it can be relatively easily transported and stored.
Vorzugsweise weist die Wellpappe auf der Vorratsrolle eine durchgehende erste Deckellage, mindestens eine Zwischenlage und mindestens eine schuppenförmige zweite Deckellage auf. Eine Wellpappe mit einer durchgehenden ersten Deckellage, die mit einer gewellten Zwischenlage verbunden ist, wird auch als einseitige Wellpappe bezeichnet. Eine einseitige Wellpappe ist relativ biegeweich und kann gut als Rollenware verwendet werden. Durch die zweite schuppenförmige Deckellage, die mit der Zwischenlage verbunden ist, wird erreicht, dass die Wellpappe in eine Richtung biegesteif ist und in die entgegengesetzte Richtung biegeweich. Dies wird dadurch erreicht, dass sich die Schuppen der zweiten Deckellage überlappen, wobei sie sich bei einer Biegung um die durchgehende erste Deckellage gegeneinander verschieben können. Sollte die Wellpappe allerdings in entgegengesetzter Richtung gebogen werden, stößt der überlappte Teil einer Schuppe gegen die Verbindungsstelle der benachbarten Schuppe mit der Zwischenlage, so dass eine Biegung verhindert wird. Die Wellpappe ist in diese Richtung entsprechend biegesteif, während sie in der anderen Richtung problemlos aufgerollt werden kann. Für Stirndeckel ist es in der Regel ausreichend, dass die Stirndeckel in einer Richtung biegesteif sind. Das Versteifen der Wellpappe erfolgt dabei sozusagen durch das ebene Ausbreiten der Wellpappe nach dem Abziehen von der Vorratsrolle.The corrugated cardboard preferably has a continuous first cover layer, at least one intermediate layer and at least one flaky second cover layer on the supply roll. A corrugated cardboard with a continuous first cover layer, with a corrugated intermediate layer is also referred to as single-sided corrugated board. A single-faced corrugated board is relatively flexible and can be used well as a roll product. By the second scale-shaped cover layer, which is connected to the intermediate layer, it is achieved that the corrugated cardboard is rigid in one direction and flexible in the opposite direction. This is achieved in that the scales of the second cover layer overlap, whereby they can move against each other at a bend around the continuous first cover layer. However, should the corrugated board be bent in the opposite direction, the overlapped portion of a scale will strike against the juncture of the adjacent scale with the intermediate layer, thus preventing bending. The corrugated board is correspondingly rigid in this direction, while it can be easily rolled up in the other direction. For end covers, it is usually sufficient that the end covers are rigid in one direction. The stiffening of the corrugated board takes place, so to speak, by the flat spreading of the corrugated cardboard after removal from the supply roll.
Vorzugsweise weisen die einzelnen Schuppen der schuppenförmigen Deckellage gleichartige oder verschiedenartige Formen auf, die formschlüssig und/oder kraftschlüssig mit einander in Verbindung treten können. Dabei ist es denkbar, dass die Schuppen einfache Rechteckformen aufweisen, deren Kanten Stoß-an-Stoß in Wirkverbindung treten können und so wirksame Biegebegrenzungen in eine Richtung festlegen können. Es ist auch denkbar, dass die einzelnen Schuppen puzzelteilartige Formen aufweisen. Dazu können benachbarte Schuppen gleiche oder verschiedene Formen aufweisen. Bei solchen puzzelartigen Schuppen können Teile der einen Schuppe in Bereiche der benachbarten Schuppe eingreifen. Hier kann dann eine form- und kraftschlüssige Verbindung entstehen, die beispielsweise nach Überwindung eines definierten Kraftbereichs wieder gelöst werden können.Preferably, the individual scales of the scale-shaped cover layer have similar or different shapes, which can positively and / or non-positively connect with each other. It is conceivable that the scales have simple rectangular shapes, the edges of which can come into operative connection shock-to-joint and so can set effective bending limits in one direction. It is also conceivable that the individual scales have puzzle-like shapes. For this purpose, adjacent scales may have the same or different shapes. In such puzzle-like scales parts of the one scale can engage in areas of the adjacent scale. Here can then form a positive and non-positive connection arise, which can be solved, for example, after overcoming a defined force range again.
Weiterhin können auch Dreiecksformen, Rautenformen, und allgemein vieleckige Formen mit Vorteil eingesetzt werden. Es ist auch denkbar, dass die einzelnen Schuppen wenigstens in Teilbereichen Kreis- oder Kurvenformen aufweisen. Beispielsweise seien dazu halbmondförmige oder S-förmige Schuppen genannt.Furthermore, triangular shapes, diamond shapes, and general polygonal shapes are used with advantage. It is also conceivable that the individual scales have circular or curved shapes, at least in some areas. For example, crescent-shaped or S-shaped scales are mentioned.
Bevorzugterweise werden benachbarte Schuppen der zweiten Deckellage beim Versteifen miteinander verbunden. Dadurch wird auf einfache Weise erreicht, dass die Wellpappe in beide Richtungen biegesteif ist.Preferably, adjacent scales of the second cover layer are joined together during stiffening. This achieves a simple way that the corrugated cardboard is rigid in both directions.
Dabei ist besonders bevorzugt, dass die benachbarten Schuppen miteinander verklebt, vernäht oder verprägt werden. Durch diese Fügeverfahren wird eine sichere Verbindung benachbarter Schuppen erreicht, wobei dafür nur ein geringer Aufwand erforderlich ist. Insbesondere das Verprägen, das auch als Vercrimpen bezeichnet wird, hat dabei den Vorteil, dass keine Fremdstoffe in die Wellpappe eingebracht werden. Da die Schuppen in der Regel aus Papier gebildet sind, können nicht mehr benötigte Stirnseiten und Schnittreste einfach recycelt werden. Dazu können die nicht mehr benötigten Stirnseiten und Schnittreste auch direkt wieder der Pulpe einer Papiermaschine zugeführt werden.It is particularly preferred that the adjacent scales are glued together, sewn or embossed. By this joining method, a secure connection of adjacent scales is achieved, but only a small effort is required. In particular, the embossing, which is also referred to as crimping, has the advantage that no foreign substances are introduced into the corrugated board. Since the scales are usually made of paper, no longer needed end faces and cut remnants can be easily recycled. For this purpose, the end faces and cut remnants that are no longer required can also be returned directly to the pulp of a paper machine.
In einer bevorzugten Ausführungsform weist die Wellpappe auf der Vorratsrolle nur eine erste Deckellage und mindestens eine gewellte Zwischenlage auf, wobei die Wellpappe beim Versteifen mit mindestens einer zweiten Deckellage versehen wird. Eine Wellpappe mit nur einer Deckellage und ein oder zwei Zwischenlagen ist relativ biegeweich und kann einfach als Rollenware bevorratet werden. Durch das Anbringen der zweiten Deckellage nach dem Abziehen der Wellpappe von der Vorratsrolle wird die Wellpappe in beide Richtungen biegesteif und kann so gut zu Stirndeckeln weiterverarbeitet werden.In a preferred embodiment, the corrugated cardboard on the supply roll only on a first cover layer and at least one corrugated intermediate layer, wherein the corrugated cardboard is provided during stiffening with at least a second cover layer. A corrugated board with only one cover layer and one or two intermediate layers is relatively flexible and can be easily stored as a roll. By attaching the second cover layer after removing the corrugated cardboard from the supply roll, the corrugated cardboard is rigid in both directions and can be further processed so well to end covers.
Dabei ist besonders bevorzugt, dass die zweite Deckellage von einer Vorratsrolle zugeführt wird. Die zweite Deckellage, die in der Regel aus Papier oder Karton gebildet ist, liegt also ebenfalls als Rollenware vor. Falls die erste Deckellage zwei gewellte Zwischenlagen aufweist, werden entsprechenderweise zwei weitere Deckellagen zugeführt. Die Aufbewahrung der zweiten Deckellagen als Vorratsrolle ist dabei relativ Platz sparend und ermöglicht eine einfache Zuführung.It is particularly preferred that the second cover layer is supplied from a supply roll. The second cover layer, which is usually off Paper or cardboard is formed, so is also available as a roll. If the first cover layer has two corrugated intermediate layers, two further cover layers are correspondingly supplied. The storage of the second cover layers as a supply roll is relatively space-saving and allows easy feeding.
Vorzugsweise wird die zweite Deckellage mit der Zwischenlage und/oder der ersten Deckellage verklebt, vernäht oder verprägt. Dafür kann die Zwischenlage beispielsweise mit einem Stärkeleim bestrichen sein, wobei die zweite Deckellage mit Hilfe einer Walze an die Zwischenlage herangeführt wird. Beim Nähen erfolgt dagegen eine formschlüssige Verbindung zwischen der zweiten Deckellage mit der Zwischenlage und/oder der ersten Deckellage, die entsprechend hoch belastbar ist. Beim Verprägen, das auch Vercrimpen genannt wird, wird die zweite Deckellage mit der Zwischenlage und/oder der ersten Deckellage mit Hilfe von Prägewalzen oder Prägerädern verbunden.Preferably, the second cover layer is glued, sewn or embossed with the intermediate layer and / or the first cover layer. For this purpose, the intermediate layer can be coated, for example, with a starch glue, wherein the second cover layer is guided by means of a roller to the intermediate layer. When sewing, however, there is a positive connection between the second cover layer with the intermediate layer and / or the first cover layer, which is correspondingly high load capacity. In embossing, which is also called crimping, the second cover layer is connected to the intermediate layer and / or the first cover layer by means of embossing rollers or embossing wheels.
Vorteilhafterweise werden die Stirndeckel mit einem Laser aus der Wellpappe ausgeschnitten, wobei vorzugsweise die zweite Deckellage bzw. die benachbarten Schuppen mit dem Laser auch heißverklebt werden. Mit dem gleichen Laser, der zum Ausschneiden der Stirndeckel verwendet wird, erfolgt also auch eine Heißverklebung der zweiten Deckellage mit der Zwischenlage. Gegebenenfalls muss nur eine Brennweite des Lasers angepasst werden. Das Versteifen der Wellpappe und das Erzeugen der Stirndeckel kann dann in einer einzigen Bearbeitungsstation erfolgen und ist dementsprechend schnell und kostengünstig.Advantageously, the end covers are cut out of the corrugated cardboard with a laser, wherein preferably the second cover layer or the adjacent flakes are also hot-bonded with the laser. With the same laser that is used to cut the front cover, so also a hot bonding of the second cover layer takes place with the liner. If necessary, only one focal length of the laser has to be adapted. The stiffening of the corrugated board and the production of the end cover can then be done in a single processing station and is therefore fast and inexpensive.
Die Aufgabe wird durch eine Rollenpackmaschine der eingangs genannten Art dadurch gelöst, dass sie eine Abwickeleinrichtung und eine Versteifungseinrichtung aufweist, wobei in der Abwickeleinrichtung Wellpappe von einer Vorratsrolle abziehbar ist und die abgezogene Wellpappe in der Versteifungseinrichtung versteifbar ist.The object is achieved by a roll packaging machine of the type mentioned above in that it has an unwinding device and a stiffening device, wherein in the unwinding corrugated cardboard is removable from a supply roll and the withdrawn corrugated cardboard is stiffened in the stiffening device.
Die Wellpappe kann also als Rollenware auf einer Vorratsrolle bevorratet werden. Das Versteifen der Wellpappe erfolgt erst in der Versteifungseinrichtung der Rollenpackmaschine, also erst dann, wenn eine steife Wellpappe erforderlich ist. Die bis dahin biegeweiche Wellpappe kann dagegen leicht bevorratet werden.The corrugated board can therefore be stored as a roll on a supply roll. The stiffening of the corrugated board takes place only in the stiffening device of the roll packaging machine, ie only when a stiff corrugated cardboard is required. By contrast, the soft, corrugated cardboard that was previously soft can easily be stored.
Dabei ist besonders vorteilhaft, dass die Rollenpackmaschine eine Schneideinrichtung aufweist. In der Rollenpackmaschine erfolgt also nicht nur das Versteifen der Wellpappe, sondern auch das Zuschneiden der Stirndeckel. Die Herstellung der Stirndeckel erfolgt dann direkt am Verwendungsort für die Stirndeckel, nämlich in der Rollenpackmaschine. Transport und Lagerung der Stirndeckel werden dadurch stark vereinfacht. Dabei ist besonders bevorzugt, dass die Wellpappe eine durchgehende erste Deckellage, mindestens eine gewellte Zwischenlage und mindestens eine schuppenförmige Deckellage aufweist. Benachbarte Schuppen der schuppenförmigen Deckellage können dann in der Versteifungseinrichtung miteinander verbindbar sein. Die Versteifung der Wellpappe ist dann ohne großen Aufwand in der Rollenpackmaschine möglich.It is particularly advantageous that the roll packaging machine has a cutting device. In the roll packaging machine, not only the stiffening of the corrugated board, but also the cutting of the end cover. The production of the end cover is then directly at the place of use for the end cover, namely in the roll packaging machine. Transport and storage of the end covers are greatly simplified. It is particularly preferred that the corrugated cardboard has a continuous first cover layer, at least one corrugated intermediate layer and at least one scale-like cover layer. Adjacent scales of the scale-shaped cover layer can then be connected to one another in the stiffening device. The stiffening of the corrugated board is then possible without great effort in the roll packaging machine.
In einer anderen bevorzugten Ausführungsform weist die Rollenpackmaschine mindestens eine Zuführeinrichtung für eine Deckellage auf, die in der Versteifungseinrichtung mit der Wellpappe verbindbar ist. Dies stellt eine weitere einfache Möglichkeit dar, eine Wellpappe zu versteifen, in der aus einer einseitigen Wellpappe eine zweiseitige Wellpappe erzeugt wird.In another preferred embodiment, the roll packaging machine has at least one feed device for a cover layer, which can be connected to the corrugated cardboard in the stiffening device. This is another easy way to stiffen a corrugated board in which a two-sided corrugated board is produced from a single-sided corrugated board.

Für die zweite Deckellage wird vorteilhafter Weise eine Materialbahn aus Testliner oder Kraftliner verwendet, die beispielsweise PE beschichtet ist. Wenn die Stirndeckel höhere Kräfte aushalten sollen, ist es zweckmäßig, zwei gewellte Zwischenlagen zu verwenden, die zunächst an einer als Mittellage ausgebildeten ersten Deckellage angeordnet sind und so auf einer Vorratsrolle aufgewickelt sind. Jede Zwischenlage wird dann nach dem Abziehen von der Vorratsrolle mit einer weiteren Deckellage versehen, so dass eine sehr steife Wellpappe erhalten wird. Die Wellpappe mit den Deckellagen und den Zwischenlagen wird in der Regel aus Papier oder Karton hergestellt. Aber auch andere Materialpaarungen sind denkbar.For the second cover layer is advantageously used a material web of testliner or kraftliner, which is coated for example PE. If the front cover should withstand higher forces, it is expedient to use two corrugated intermediate layers, which are initially arranged on a central position designed as a first cover layer and are wound on a supply roll. Each liner is then provided after removal from the supply roll with another cover layer, so that a very stiff corrugated board is obtained. The corrugated board with the cover layers and the intermediate layers is usually made of paper or cardboard. But other material pairings are conceivable.

Ebenso selbstverständlich sollte es sein, dass die auf dem oberen Bildbereich dargestellten Einrichtungen (2,8,10,11,12,13,17) im Normalfall beidseitig der durch die Fördereinrichtung 16 definierten Wegstrecke der zu verpackenden Materialbahnrollen 15 vorgesehen sind und hier der Einfachheit halber ausgelassen worden sind.It goes without saying that the cutting
Der nach Erzeugung der Stirndeckel aus der Wellpappe 1 entstehende Verschnitt kann praktischer Weise wieder der Pulpe einer nicht dargestellten Papier- beziehungsweise Pappmaschine zuführbar sein.The resulting after the production of the end cover of the corrugated cardboard 1 waste can practically be re-fed to the pulp of a paper or board machine, not shown.
