Description

Die Erfindung betrifft ein Verfahren zum Falzen von Bogen gemäß Anspruch 1 und eine Falzmaschine zum Falzen von Bogen gemäß dem Oberbegriff von Anspruch 5.The invention relates to a method for folding sheets according to claim 1 and a folding machine for folding sheets according to the preamble of claim 5.

Stand der TechnikState of the art

Aus dem Stand sind zum einen Taschenfalzmaschinen bekannt. Der Aufbau einer Taschenfalzmaschine mit einer Vielzahl von Taschenfalzwerken geht aus der DE 10 2004 041 471 A1 hervor. Ein jeweiliges Taschenfalzwerk besteht dabei aus einer Falztasche und drei Falzwalzen, welche in zwei Falzwalzenpaaren angeordnet sind. Weiter sind Schwertfalzmaschinen bekannt. Aus der DE 29 40 360 A1 ist ein Einzelschwertfalzwerk zum Falzen von bedruckten und vorgefalzten Bogen bekannt. In Kombifalzmaschinen werden Taschenfalzwerke und Schwertfalzwerke kombiniert. Dabei werden in einer ersten Falzstation in Taschenfalzwerken Parallelbrüche und in einer nachfolgenden Falzstation in Schwertfalzwerken Kreuzbrüche gefalzt. Die DE 10 2006 055 301 A1 zeigt Kombifalzmaschinen mit einer Mehrzahl von Taschenfalzwerken und nachranging angeordneten Schwertfalzwerken.From a standing pocket folding machines are known. The construction of a Taschenfalzmaschine with a variety of Taschenfalzwerken goes out of the DE 10 2004 041 471 A1 out. A respective pocket folder consists of a folding pocket and three folding rollers, which are arranged in two pairs of folding rollers. Furthermore, Schwertfalzmaschinen are known. From the DE 29 40 360 A1 is a single sword folding machine for folding of printed and pre-folded sheet known. Combination folding machines combine pocket folders and knife folders. Here are folded in a first folding station in Taschenfalzwerken parallel breaks and in a subsequent folding station in Schwertfalzwerken cross breaks. The DE 10 2006 055 301 A1 shows Kombifalzmaschinen with a plurality of Taschenfalzwerken and nachranging arranged Schwertfalzwerken.

Um die Ausbringung von Falzmaschinen, sprich deren Produktivität, zu erhöhen, wird die Durchlaufgeschwindigkeit der Bogen durch die Falzmaschine üblicherweise erhöht. Durch die Erhöhung der Geschwindigkeit erfährt ein jeweiliger Falzbogen jedoch Deformierungen und Beschädigungen, was zu deutlichen Qualitätseinbußen führt.In order to increase the output of folding machines, ie their productivity, the speed of passage of the sheets is usually increased by the folding machine. By increasing the speed, however, a respective folded sheet undergoes deformations and damage, which leads to significant quality losses.

Aus der DE 103 36 757 A1 gehen Verfahren zum Falzen von sich schuppenstromartig überlappend zugeführten Bogen hervor. Durch die Anwendung der Verfahren soll die Produktivität der Falzmaschinen gesteigert werden, ohne die Durchlaufgeschwindigkeit der Bogen durch die Maschine zu erhöhen. Dazu werden die Falzspaltweiten der einziehenden Falzwalzen in Teilphasen eines kontinuierlichen Falzvorgangs falzzyklusabhängig vergrößert bzw. verkleinert. Ein derartiges Vorgehen ist nachteilig, da zur Anpassung der Falzspaltweite zum einen eine komplizierte mechanische Lagerung der Falzwalzen als auch eine aufwendige Ansteuerung der Antriebe zur Anpassung der Falzspaltweite notwendig sind. Weiter nachteilig ist, dass sich aufeinander folgende Bogen in den Falzwerken begegnen und mit einer Relativgeschwindigkeit zueinander bewegt werden. Dabei können die Bogen beschädigt werden und es kann zu sogenannten Markierungen kommen. Durch die Relativbewegung beider Bogen können erhöhte Falztoleranzen, elektrostatische Aufladung und Störungen im Bereich des Tascheneinlaufs verursacht werden.From the DE 103 36 757 A1 For example, methods for folding bow-shaped overlapping sheets are disclosed. By using the methods, the productivity of the folding machines is to be increased without increasing the speed of passage of the sheets through the machine. For this purpose, the folding gap widths of the feeding folding rollers are increased or reduced depending on the folding cycle in partial phases of a continuous folding operation. Such a procedure is disadvantageous because to adapt the folding gap width on the one hand, a complicated mechanical storage of the folding rollers as well as a complex control of the drives for adjusting the Folding gap width are necessary. Another disadvantage is that successive sheets meet in the folding units and are moved relative to each other at a relative speed. The bows can be damaged and it can lead to so-called markings. The relative movement of both sheets can cause increased folding tolerances, electrostatic charge and disturbances in the area of the pocket inlet.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es deshalb, ein Falzverfahren zu beschreiben und eine Falzmaschine zu schaffen, welche die Nachteile des Standes der Technik behebt und keine konstruktiven Abänderungen bestehender Falzwerke erfordert.The object of the present invention is therefore to describe a folding method and to provide a folding machine, which overcomes the disadvantages of the prior art and does not require any structural modifications of existing folding units.

Gelöst wird diese Aufgabe durch ein Verfahren zum Falzen gemäß Anspruch 1 und eine Falzmaschine mit den kennzeichnenden Merkmalen von Anspruch 5.This object is achieved by a method for folding according to claim 1 and a folding machine with the characterizing features of claim 5.

Die Erfindung betrifft ein Verfahren zum überschuppten Falzen von bogenförmigen Elementen, insbesondere von bedruckten Bogen aus Papier, Pappe und dergleichen in einer Falzmaschine. Die Falzmaschine weist dazu mindestens eine Falzstation mit mindestens einem Falzwerk auf. Die bogenförmigen Elemente werden in einer Transportrichtung mit ihrer Vorderkante voraus mit einer Überschuppung der Falzstation zugeführt. Die Überschuppung entspricht dabei erfindungsgemäß maximal der ersten Falzlänge. In dem Falzwerk wird in einem jeweiligen bogenförmigen Element ein Falzbruch quer zur Transportrichtung erzeugt und die bogenförmigen Elemente werden mit einer ersten Falzlänge nach oben gefalzt, d.h. die Vorderkante eines jeweiligen bogenförmigen Elements wird auf dessen Oberseite abgelegt. Dabei ist der Falz derart, dass der Abstand zwischen der abgelegten Vorderkante eines ersten bogenförmigen Elements und der Vorderkante eines nachfolgenden noch nicht gefalzten bogenförmigen Elements größer oder gleich Null ist. D.h. die Vorderkanten sind auch nach dem ersten Falz beabstandet voneinander oder liegen im Grenzfall aufeinander. Die Vorderkante eines ersten bogenförmigen Elements liegt damit in Transportrichtung betrachtet stromabwärtig der Vorderkante eines nachfolgenden noch nicht gefalzten bogenförmigen Elements. Damit ist sichergestellt, dass sich ein erstes einlaufendes bogenförmiges Element und ein nachfolgend einlaufendes zweites bogenförmiges Element nicht begegnen.The invention relates to a method for overlapping folding of sheet-shaped elements, in particular of printed sheets of paper, cardboard and the like in a folding machine. For this purpose, the folding machine has at least one folding station with at least one folding unit. The arcuate elements are fed in advance in a transport direction with its front edge with a Überuppung the folding station. According to the invention, the overlap corresponds at most to the first fold length. In the folding unit, a fold break is produced transversely to the transport direction in a respective arcuate element and the arcuate elements are folded upwards with a first fold length, ie the leading edge of a respective arcuate element is deposited on its upper side. In this case, the fold is such that the distance between the stored front edge of a first arcuate element and the front edge of a subsequent not yet folded arcuate element is greater than or equal to zero. That is, the leading edges are spaced from each other even after the first fold or lie in the limit case to each other. The leading edge of a first arcuate element is thus located in the transport direction downstream of the leading edge of a subsequent not yet folded arcuate element. This is ensures that a first incoming arcuate element and a subsequent incoming second arcuate element does not meet.

Das erfindungsgemäße überschuppte Falzen kann dabei in einer Taschenfalzstation oder einer Parallelschwertfalzstation durchgeführt werden. Die Parallelschwertfalzstation weist dabei ein erstes oberes und von oben wirkendes Falzschwert auf. Nach dem oben beschriebenen überschuppten Falzen kann das dabei erzeugte Falzprodukt durch weiteres Falzen, sei es in nachfolgenden Falzwerken derselben Falzstation und / oder in nachfolgenden Falzstationen, weiter bearbeitet werden.The uncoupled folding according to the invention can be carried out in a pocket folding station or a parallel sword folding station. The Parallelschwertfalzstation has a first upper and acting from above folding blade. After the above-mentioned over-folded seaming, the folded product produced thereby can be further processed by further folding, be it in subsequent folding units of the same folding station and / or in subsequent folding stations.

Beim Falzen von Bogen in ungeschuppter Weise nach dem Stand der Technik muss zwischen den einem Falzwerk zugeführten Bogen jeweils ein Abstand von ca. 5 bis 8 cm vorliegen. Dadurch wird erreicht, dass der Falzvorgang im ersten Falzwerk bereits abgeschlossen ist, bevor ein nachfolgender Bogen in das Falzwerk einläuft. Durch Anwendung des erfindungsgemäßen Verfahrens kann auf den Abstand der Bogen beim Einlauf in die zweite Falzstation verzichtet werden, die Bogen werden sogar mit einer Überschuppung gefahren. Durch die Überschuppung der Bogen können bei gleicher Geschwindigkeit und Qualität mehr Bogen gefalzt werden und die Ausbringung der Falzmaschine wird erhöht. Eine Anpassung der Falzwerke ist dabei nicht notwendig.When folding sheets in an unpaved manner according to the prior art, a distance of approximately 5 to 8 cm must be present between the sheets fed to a folding unit. This ensures that the folding in the first folder is already completed before a subsequent sheet enters the folder. By applying the method according to the invention can be dispensed with the distance of the sheet when entering the second folding station, the sheets are even driven with a Überuppung. Due to the overlapping of the sheets more sheets can be folded at the same speed and quality and the output of the folding machine is increased. An adaptation of the folding units is not necessary.

Die Erfindung betrifft auch eine Falzmaschine zum Falzen von Bogen aus Papier, Pappe und dergleichen mit mindestens einer ersten und einer zweiten Falzstation. Zwischen der ersten und der zweiten Falzstation ist eine Transporteinrichtung angeordnet. Die Falzstationen weisen jeweils von Antrieben angetriebene Falzwalzen auf; die Transporteinrichtung verfügt ebenfalls über einen Antrieb. Die Antriebe sind jeweils mit einer gemeinsamen Steuereinheit verbunden und werden von dieser angesteuert. Die Transportgeschwindigkeit der ersten Falzstation ist dabei größer als die Transportgeschwindigkeit von Transporteinrichtung und zweiter Falzstation. In vorteilhafter Weise werden dadurch die Produkte zwischen erster und zweiter Falzstation überschuppend transportiert.The invention also relates to a folding machine for folding sheets of paper, cardboard and the like with at least a first and a second folding station. Between the first and the second folding station, a transport device is arranged. The folding stations each have drive rollers driven by folding rollers; The transport device also has a drive. The drives are each connected to a common control unit and are controlled by this. The transport speed of the first folding station is greater than the transport speed of the transport device and the second folding station. Advantageously, thereby the products between the first and second folding station are transported overshadowing.

In einer vorteilhaften Weiterbildung der erfindungsgemäßen Falzmaschine ist der zweiten Falzstation eine dritte Falzstation nachgeordnet. Diese kann Taschenfalzwerke oder Schwertfalzwerke aufweisen.
In einer vorteilhaften Weiterbildung der erfindungsgemäßen Falzmaschine ist mindestens einer Falzstation eine Vorrichtung zum Aufbringen von Klebstoff auf die Produkte vorangestellt. In einer weiteren vorteilhaften Ausführungsform ist mindestens einer Falzstation eine Vorrichtung zum Beschneiden der Produkte nachgeordnet. Durch die Vorrichtung zum Aufbringen von Klebstoff und die Vorrichtung zum Beschneiden der Produkte ist es in vorteilhafter Weise möglich, aus den Bogen kleine Bücher, sogenannte Booklets, herzustellen.
In einer vorteilhaften Weiterbildung der erfindungsgemäßen Falzmaschine ist mindestens einer Falzstation eine Vorrichtung zum Pressen der Produkte nachgeordnet. Durch ein Abpressen der Produkte kann in vorteilhafter Weise ein Aufbauchen der Produkte verhindert werden.In an advantageous development of the folding machine according to the invention, the second folding station is followed by a third folding station. This can have pocket folders or Schwertfalzwerke.
In an advantageous development of the folding machine according to the invention, at least one folding station is preceded by a device for applying adhesive to the products. In a further advantageous embodiment, at least one folding station is arranged downstream of a device for trimming the products. By the device for applying adhesive and the device for trimming the products, it is possible in an advantageous manner to produce small books, so-called booklets, from the sheets.
In an advantageous development of the folding machine according to the invention, at least one folding station is arranged downstream of a device for pressing the products. By squeezing the products can be prevented bulging of the products in an advantageous manner.

Hinsichtlich weiterer vorteilhafter Ausgestaltungen der Erfindung wird auf die Unteransprüche sowie die Beschreibung eines Ausführungsbeispiels unter Bezugnahme auf die beiliegenden Zeichnungen verwiesen.With regard to further advantageous embodiments of the invention, reference is made to the dependent claims and the description of an embodiment with reference to the accompanying drawings.

Ausführungsbeispielembodiment

Das erfindungsgemäße Verfahren zum überschuppten Falzen von Bogen aus Papier, Pappe und dergleichen in einer Falzmaschine kann beispielsweise wie folgt umgesetzt sein:

  • In einem ersten Schritt werden Bogen in einer ersten Transportrichtung zu einer ersten Falzstation transportiert. Die kürzeren Seiten eines jeweiligen Bogens befinden sich dabei parallel zur ersten Transportrichtung. In einem zweiten Schritt erfolgt das Querfalzen der Bogen in der ersten Falzstation. Dabei entstehen erste Falzprodukte. In einem dritten Schritt werden die ersten Falzprodukte mittels einer Transporteinrichtung in eine zweite Transportrichtung umgelenkt und nachfolgend weitertransportiert. Die zweite Transportrichtung ist senkrecht zur ersten Transportrichtung. Die längeren Seiten eines jeweiligen ersten Falzprodukts sind dabei parallel zur zweiten Transportrichtung ausgerichtet. Die Falzprodukte werden von der Transporteinrichtung so weiter transportiert und einer Taschenfalzwerke aufweisenden zweiten Falzstation zugeführt, dass sich die Falzprodukte überschuppen. D. h. das stromaufwärtige Ende eines ersten Falzproduktes wird von einem nachfolgenden zweiten Falzprodukt überdeckt. In einem vierten Schritt erfolgt in der zweiten Falzstation ein zweimaliges Falzen. Bei den Falzen handelt es sich dabei um außermittige Zick-Zack- oder Zick-Zack-Wickel oder Wickelfalze mit Falzbrüchen in gleichen Abständen. D. h. alle Falztaschen habe die gleiche Einlauflänge. Zur Erzeugung des ersten Falzes in dieser Falzstation läuft das erste Falzprodukt in eine obere Falztasche ein. Während dieses vierten Schrittes entstehen zweite Falzprodukte.
  • Das zweite Falzprodukt kann anschließend mittels einer zweiten Transporteinrichtung weitertransportiert und einer dritten Falzstation zugeführt werden. Dort wird das zweite Falzprodukt quer zur längeren Seite des zweiten Falzprodukts mittig gefalzt, wobei ein drittes Falzprodukt entsteht. Der Falz kann dabei in einem Taschenfalzwerk oder einem Schwertfalzwerk erzeugt werden.
The method according to the invention for over-folding of sheets of paper, cardboard and the like in a folding machine can be implemented, for example, as follows:
  • In a first step, sheets are transported in a first transport direction to a first folding station. The shorter sides of each sheet are parallel to the first transport direction. In a second step, the transverse folding of the sheets takes place in the first folding station. This results in first folded products. In a third step, the first folded products are deflected by means of a transport device in a second transport direction and subsequently transported on. The second transport direction is perpendicular to the first transport direction. The longer sides of a respective first folded product are aligned parallel to the second transport direction. The folded products are transported by the transport device so on and a second folding station having Taschenfalzwerke fed that fold over the folded products. Ie. the upstream end of a first folded product is covered by a subsequent second folded product. In a fourth step, a double folding takes place in the second folding station. The folds are eccentric zig-zag or zig-zag winding or winding folds with fold breaks at equal intervals. Ie. all folding pockets have the same inlet length. To produce the first fold in this folding station, the first folded product enters an upper folding pocket. During this fourth step arise second folded products.
  • The second folded product can then be transported further by means of a second transport device and fed to a third folding station. There, the second folded product is folded in the middle transversely to the longer side of the second folded product, whereby a third folded product is formed. The fold can be generated in a pocket folder or a sword folder.

In Fig. 1a sind zwei bogenförmige Elemente, hier zwei Signaturen 7a, 7b dargestellt, welche in Transportrichtung T von einer ersten Falzstation 3 zu einer zweiten Falzstation 4 transportiert werden. Der Abstand b zwischen erster Signatur 7a und zweiter Signatur 7b liegt üblicherweise im Bereich von 5 bis 8 cm. In der nachfolgenden zweiten Falzstation 4 werden die Signaturen 7a und 7b dreimal gefalzt, wobei Bogenteile mit gleicher Abmessung entstehen. Die Bogenteile sind in Fig. 1a angedeutet: durch die Falze in der zweiten Falzstation 4 wird eine jeweilige Signatur 7a, 7b in vier gleichgroße Teile geteilt.In Fig. 1a are two arcuate elements, here two signatures 7a, 7b shown, which are transported in the transport direction T from a first folding station 3 to a second folding station. The distance b between the first signature 7a and the second signature 7b is usually in the range of 5 to 8 cm. In the following second folding station 4, the signatures 7a and 7b are folded three times, with bow parts with the same Dimension arise. The arch parts are in Fig. 1a indicated: by the folds in the second folding station 4, a respective signature 7a, 7b divided into four equal parts.

In Fig. 1b sind zwei Signaturen 7a, 7b dargestellt, welche von einer ersten Falzstation 3 kommend in Transportrichtung T zu einer zweiten Falzstation 4 transportiert werden. Die Signaturen 7a und 7b werden dabei überschuppt transportiert. Die zweite Signatur 7b überdeckt das stromaufwärtige Ende der Signatur 7a. Im Beispiel von Fig. 1b werden drei Falze erzeugt, so dass eine jeweilige Signatur 7a, 7b in vier gleiche Bogenteile geteilt wird. Die Überschuppung c beträgt ein Viertel der Länge der Signaturen 7a, 7b. Im Gegensatz zum in Fig. 1a dargestellten beabstandeten Transport der zwei Signaturen 7a und 7b wurde für den überschuppten Transport gemäß Fig. 1b die zweite Signatur 7b um die Summe aus Signaturabstand b und Überschuppung c in Transportrichtung T verschoben. Um die Signaturen 7a, 7b in der zweiten Falzstation 4 zu falzen, müssen die Signaturen 7a, 7b eine geringere Wegstrecke zurücklegen. D. h. bei gleichbleibender Maschinengeschwindigkeit, d.h. Transportgeschwindigkeit, können mehr Signaturen zu fertigen Falzprodukten verarbeitet werden und die Ausbringung der Falzmaschine 1 kann erhöht werden. Alternativ kann die Ausbringung der Falzmaschine 1 beibehalten werden und die Transportgeschwindigkeit der Signaturen 7a, 7b reduziert werden, insbesondere dann, wenn es sich um schwierig zu verarbeitendes Material handelt, welches zur Sicherstellung einer hohen Qualität der Produkte eine geringere Transportgeschwindigkeit erfordert.In Fig. 1b two signatures 7a, 7b are shown, which are transported from a first folding station 3 in the transport direction T to a second folding station 4. The signatures 7a and 7b are thereby transported überuppt. The second signature 7b covers the upstream end of the signature 7a. In the example of Fig. 1b Three folds are generated so that a respective signature 7a, 7b is divided into four equal parts of the sheet. The overlap c is one quarter of the length of the signatures 7a, 7b. Unlike in Fig. 1a shown spaced transport of the two signatures 7a and 7b has been for the überuppten transport according to Fig. 1b the second signature 7b is shifted in the transport direction T by the sum of the signature spacing b and the overlapping c. In order to fold the signatures 7a, 7b in the second folding station 4, the signatures 7a, 7b have to travel a smaller distance. Ie. at constant machine speed, ie transport speed, more signatures can be processed into finished folded products and the output of the folding machine 1 can be increased. Alternatively, the application of the folding machine 1 can be maintained and the transport speed of the signatures 7a, 7b can be reduced, especially if it is difficult to process material, which requires a lower transport speed to ensure a high quality of the products.

In den Fig. 2a bis 2c ist dargestellt, wie die überschuppten Signaturen 7a, 7b in den Taschenfalzwerken der zweiten Falzstation 4 gefalzt werden. In Fig. 2a ist eine erste Momentaufnahme dargestellt. Die Signaturen 7a, 7b werden von einer ersten Falzstation 3 kommend über einen Zuführtisch 9 in Transportrichtung T der zweiten Falzstation 4 zugeführt. Die Signaturen 7a, 7b weisen dabei eine Überschuppung c auf. Die erste Signatur 7a ist bereits in die erste, oben liegende Falztasche 11 eingelaufen. Der Taschenanschlag 12 der Falztasche 11 wurde auf eine Einlauflänge (Falzlänge) 14 eingestellt. Die Einlauflänge 14 entspricht hier einem Drittel der Länge der Signaturen 7a, 7b. In Fig. 2b ist eine zweite Momentaufnahme dargestellt. Die erste Signatur 7a hat die erste oben liegende Falztasche 11 bereits verlassen, durch die Falzwalzen 15 wurde ein erster Falzbruch erzeugt und die erste Signatur 7a befindet sich bereits in der zweiten, unten liegenden, Falztasche 11. Die zweite Signatur 7b läuft gerade in die erste, oben liegende, Falztasche 11 ein. Durch die gezeigte Einstellung der Einlauflängen 14 der Falztaschen 11 ist sichergestellt, dass die Signaturen 7a und 7b sich nicht so in der zweiten Falzstation 4 begegnen, dass es zu Relativgeschwindigkeiten zwischen erster Signatur 7a und zweiter Signatur 7b kommt. Im Einlaufbereich der zweiten Falzstation 4 unterhalb der Transportwalze 16 berühren sich erste Signatur 7a und zweite Signatur 7b, werden allerdings mit der gleichen Geschwindigkeit bewegt. Da es zu keinen Relativgeschwindigkeiten zwischen erster Signatur 7a und zweiter Signatur 7b kommt, werden Markierungen verhindert. Durch den ersten Falz wird die Vorderkante 30a der ersten Signatur 7a so abgelegt, dass der Abstand zur Vorderkante 30b der nachfolgenden Signatur 7b größer Null ist. Fig. 2c stellt eine dritte Momentaufnahme dar. Die erste Signatur 7a ist bereits fertig gefalzt und wird an einer dritten Falztasche vorbeitransportiert und aus der zweiten Falzstation 4 ausgeschleust. Eine Bogenweiche 13 verhindert dabei den Einlauf der ersten Signatur 7a in die dritte Falztasche 11. In der zweiten Signatur 7b wird durch die Falzwalzen 15 ein erster Falzbruch erzeugt. Auch hier begegnen sich erste Signatur 7a und zweite Signatur 7b nicht und es kommt zu keiner Relativbewegung zwischen beiden Signaturen 7a, 7b.
Die dargestellte Falzstation 4 weist drei Falztaschen 11 auf. Erfindungsgemäß könnte die Falzstation 4 aber eine beliebige Anzahl an Falztaschen 11 aufweisen.In the Fig. 2a to 2c It is shown how the superimposed signatures 7a, 7b are folded in the pocket folders of the second folding station 4. In Fig. 2a a first snapshot is shown. The signatures 7a, 7b are fed from a first folding station 3 via a feed table 9 in the transport direction T of the second folding station 4. The signatures 7a, 7b have an overlapping c. The first signature 7a has already entered the first folding pocket 11 at the top. The pocket stop 12 of the folding pocket 11 was set to an inlet length (folding length) 14. The inlet length 14 here corresponds to one third of the length of the signatures 7a, 7b. In Fig. 2b a second snapshot is shown. The first signature 7a has already left the first folding folder 11 on the top, a first fold break has been produced by the folding rollers 15 and the first signature 7a is already in the second, The second signature 7b runs straight into the first, top, folding pocket 11. The setting of the inlet lengths 14 of the folding pockets 11 shown ensures that the signatures 7a and 7b do not meet in the second folding station 4 in such a way that relative speeds occur between the first signature 7a and the second signature 7b. In the inlet region of the second folding station 4 below the transport roller 16 touch first signature 7a and second signature 7b, however, are moved at the same speed. Since there are no relative speeds between the first signature 7a and the second signature 7b, markings are prevented. By the first fold, the leading edge 30a of the first signature 7a is deposited so that the distance to the leading edge 30b of the subsequent signature 7b is greater than zero. Fig. 2c represents a third snapshot. The first signature 7a is already finished folded and is transported past a third folding pocket and discharged from the second folding station 4. A curved switch 13 prevents the entry of the first signature 7a into the third folding pocket 11. In the second signature 7b, a first fold break is produced by the folding rollers 15. Again, first signature 7a and second signature 7b do not meet and there is no relative movement between the two signatures 7a, 7b.
The folding station 4 shown has three folding pockets 11. According to the invention, however, the folding station 4 could have any number of folding pockets 11.

In den Figuren 3a, 3b und 3c sind beispielhaft zwei mögliche Varianten für den Aufbau einer Falzmaschine 1 dargestellt. Die Falzmaschine gemäß Fig. 3a besitzt eine erste Falzstation 3, welche als Taschenfalzwerk mit einer Tasche ausgeführt ist, eine zweite Falzstation 4, welche als Taschenfalzstation mit mindestens drei Falztaschen ausgeführt ist und eine dritte Falzstation 5, welche als Taschenfalzwerk mit mindestens einer Falztasche ausgeführt ist. Die Einlauflängen der jeweiligen Falztaschen sind in Klammern angegeben und beziehen sich auf die Länge eines jeweils einlaufenden Bogens. In der ersten Falzstation 3 wird ein Quermittenfalz erzeugt. Die erzeugte Signatur wird über einen Schrägrollentisch 10 der zweiten Falzstation 4 zugeführt. Durch die Abstimmung der Transportgeschwindigkeit in der ersten Falzstation 3 und des Schrägrollentischs 10 wird erreicht, dass die Signaturen durch den Schrägrollentisch 10 in überschuppter Weise - wie in Fig. 1b dargestellt - der zweiten Falzstation 4 zugeführt werden. Dort werden drei Zick-Zack-Falze erzeugt, wobei der erste Zick-Zack-Falz in der ersten oberen Falztasche erzeugt wird. Über einen weiteren Schrägrollentisch 10 können die Signaturen von der zweiten Falzstation zu einer dritten Falzstation 5 weitertransportiert werden, wo ein Quermittenfalz als Abschlussfalz erzeugt wird. In Fig. 3b ist ein alternativer Aufbau der Falzmaschine 1 zur Herstellung desselben Produkts dargestellt. Anstelle des zweiten Schrägrollentischs 10 und dem nachfolgenden Taschenfalzwerk wird hier ein Schwertfalzwerk 5 eingesetzt. In Fig. 3c ist ein weiterer alternativer Aufbau der Falzmaschine 1 dargestellt. Die zweite Falzstation 4 ist dabei als Parallelschwertfalzwerk ausgeführt. Die Signaturen werden dem Parallelschwertfalzwerk vom Schrägrollentisch 10 in überschuppter Weise zugeführt. Um in dieser Station mehrere Parallelfalze ausführen zu können, können nach dem dargestellten Parallelschwertfalzwerk noch weitere Parallelschwertfalzwerke oder Taschenfalzwerke folgen.In the Figures 3a, 3b and 3c For example, two possible variants for the construction of a folding machine 1 are shown. The folding machine according to Fig. 3a has a first folding station 3, which is designed as a pocket folder with a pocket, a second folding station 4, which is designed as Taschenfalzstation with at least three folding pockets and a third folding station 5, which is designed as a pocket folder with at least one folding pocket. The run-in lengths of the respective folding pockets are given in brackets and refer to the length of each incoming bow. In the first folding station 3, a transverse center fold is generated. The signature generated is fed via a Schrägrollentisch 10 of the second folding station 4. By matching the transport speed in the first folding station 3 and the Schrägrollentischs 10 is achieved that the signatures by the Schrägrollentisch 10 in überuppter manner - as in Fig. 1b shown - the second folding station 4 are supplied. There are three zig-zag folds produced, wherein the first zig-zag fold is generated in the first upper folding pocket. About another Schrägrollentisch 10, the signatures can be transported from the second folding station to a third folding station 5, where a Quermittenfalz is generated as Abschlussfalz. In Fig. 3b an alternative construction of the folding machine 1 for the production of the same product is shown. Instead of the second Schrollgrollentischs 10 and the subsequent Taschenfalzwerk here a sword folder 5 is used. In Fig. 3c is another alternative construction of the folding machine 1 is shown. The second folding station 4 is designed as Parallelschwertfalzwerk. The signatures are supplied to the Parallelschwertfalzwerk from Schrägrollentisch 10 in an overlapped manner. In order to be able to execute a plurality of parallel folds in this station, further parallel sword folds or pocket folders can follow according to the illustrated parallel sword fold.

In Abhängigkeit vom Papierformat und der Maschinenkonfiguration sowie durch unterschiedliche Überschuppungen können durch die Anwendung der Erfindung verschiedenartigste Signaturen hergestellt werden:

  • So kann ein 32-Seiter durch einen Mittenfalz, nachfolgend drei Zick-Zack-Falze, nachfolgend einen Mittenfalz bei einer Überschuppung von maximal 1/4 oder ein 16-Seiter durch einen Mittenfalz, zwei nachfolgende Zick-Zack-Falze und einen Wickelfalz bei einer Überschuppung von maximal 1/4, ein 12-Seiter durch einen ersten Mittenfalz, nachfolgend zwei Wickelfalze bei einer Überschuppung von maximal 1/3 oder ein 24-Seiter durch einen ersten Mittenfalz, nachfolgend zwei Zick-Zack-Falze, nachfolgend einen Mittenfalz bei einer Überschuppung von maximal 1/3 hergestellt werden. Die Angaben zur Überschuppung beziehen sich dabei jeweils auf die zweite Falzstation.
  • Diese Aufzählung ist dabei nicht als abschließend zu verstehen, sondern soll vielmehr die vielfältigen Möglichkeiten bei Anwendung der Erfindung illustrieren. Eine Überschuppung von 1/4 ist in der Fig.1b dargestellt, in Fig. 2a beträgt die Überschuppung 1/3.
Depending on the paper format and the machine configuration as well as on different overlaps, the application of the invention makes it possible to produce a very wide variety of signatures:
  • Thus, a 32-ply through a Mittenfalz, followed by three zig-zag folds, followed by a Mittenfalz with a maximum notch 1/4 or a 16-Seiter by a Mittenfalz, two subsequent zig-zag folds and a Wickelfalz at one Overlapping of a maximum of 1/4, a 12-Seiter by a first Mittenfalz, followed by two Wickelfalze with a maximum notch 1/3 or a 24-Seiter by a first Mittenfalz, followed by two zigzag folds, followed by a Mittenfalz at one Overproduction of a maximum of 1/3 are produced. The information on overrun refers to the second folding station.
  • This list is not to be understood as exhaustive, but rather is intended to illustrate the many possibilities of using the invention. An overlap of 1/4 is in the 1b shows shown in Fig. 2a the overlap is 1/3.
