Abstract

A folder assembly for book folding in a web-fed rotary printing machine is disclosed. A paper web is printed and is then directed to a cutting cylinder, a cooperating folding blade cylinder and to a folding jaw cylinder. A pair of third or quarter folders are coordinated to the folding jaw cylinder. An upper one of these third folders is fixed and receives cross folded signatures from the folding jaw cylinder. A lower one of these third folders is shiftable laterally with respect to the upper third folder generally in a horizontal plane which is parallel to the axis of rotation of the folding jaw cylinder. A gripper cylinder is positioned intermediate the folding jaw cylinder and a transport tape system which is shiftable with, and which conveys signatures from the gripper cylinder to the lower third folder. Both upper and lower third folders can be operated concurrently or either one can be operated by itself in response to desired production demands.

Description

Die Erfindung betrifft einen Falzapparat für Buchfalzungen an einer Rollenrotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a folder for book folds on a web-fed rotary printing press according to the preamble of claim 1.

Ein Falzapparat für Buchfalzungen an einer Rollenrotationsmaschine, der einen Längstrichter, eine Anzahl von Zugwalzen, eine QuerschneideEinrichtung, einen Punktur- und Falzmesserzylinder, einen Falzklappenzylinder und zwei Transportbändersysteme für die Überführung von Signaturen vom Falzwerk zu zwei sogenannten, auf verschieden hohen Ebenen angeordneten "Dritte-Falz"-Einrichtungen aufweist, ist durch die DE-A-1 204 689 bekannt geworden.A folder for book folds on a web press, which has a longitudinal hopper, a number of draw rollers, a cross-cutting device, a puncture and folder knife cylinder, a folder cylinder and two conveyor belt systems for transferring signatures from the folder to two so-called "third parties" arranged at different levels. Folding "devices has become known from DE-A-1 204 689.

Mit dem Falzapparat nach der DE-A-1 204 689 ist nur eine Falzart möglich.Only one type of fold is possible with the folder according to DE-A-1 204 689.

Durch die FR-A-6 866 001 sind verschiebbare Falzwerke bekannt. Die Verschiebbarkeit ist jedoch in Papierlaufrichtung und nicht quer dazu, wie beim Gegenstand des Patentes.Movable folding units are known from FR-A-6 866 001. However, the displaceability is in the paper running direction and not across it, as in the subject of the patent.

Aus der DE-AS-2 107 595 ist eine steuerbare Signaturenweiche in einem Falzapparat zu entnehmen.A controllable signature switch in a folder can be found in DE-AS-2 107 595.

Zur Erzeugung von ungesammelt Zweimalacht-Seiten-Buchfalzpodukten in Rotationsdruckmaschinen mit Formzylindern mit einfachem Umfang bzw. Viermal-acht-Seiten-Buchfalzprodukten bei sog. "Doppelt-Umfang-Maschinen" waren bisher zwei Falzwerke plus zwei sog. "Dritte-Falz"-Einrichtungen" bzw. vier "Dritte-Falz"-Einrichtungen bei Doppel-Umfang-Maschinen notwendig.Up to now, two folding units plus two so-called "third-folding" devices were used to produce two-eight-page book fold products in rotary printing presses with single-cylinder forme cylinders or four-eight-page book fold products in so-called "double-circumference machines" "or four" third-fold "devices necessary for double-circumference machines.

Ausgehend von dem letztgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, den Aufwand an Falzwerken zu reduzieren, ohne die Falzmöglichkeiten einschränken zu müssen.On the basis of the last-mentioned prior art, the object of the invention is to reduce the expenditure on folding units without having to restrict the folding possibilities.

Die mit der Erfindung erzielbaren Vorteile liegen insbesondere darin, daß außer dem Einsparen von Falzzylindern mit den dazugehörigen Maschinenelementen, dem Antrieb usw. auch Wendestangen, Papierleitwalzen eingespart werden können. Außerdem werden teilweise die Papierwege verkürzt.The advantages that can be achieved with the invention are, in particular, that, in addition to the saving of folding cylinders with the associated machine elements, the drive, etc., turning bars and paper guide rollers can also be saved. In addition, the paper paths are sometimes shortened.

In nicht dargestellten Druckwerken werden in bekannter Weise Papierbahnen bedruckt. Die Druckwerke weisen Formzylinder mit einfachem Umfang (2 Nutzen) oder mit doppeltem Umfang (4 Nutzen) auf. Diese Papierbahnen oder zumindest eine Papierbahn 1 wird einem Falzapparat 2 zugeführt. Der Falzapparat 2 läßt mindestens die Produktionen A: 2 x 8 Seiten oder wahlweise B: 1 x 16 Seiten (beides ungesammelt) zu pro ganzbreiter Papierbahn, wobei die Druckwerke mit Formzylindern einfachen Durchmessers ausgerüstet sind.In printing units, not shown, paper webs are printed in a known manner. The printing units have forme cylinders with a single circumference (2 uses) or with a double circumference (4 uses). This paper web or at least one paper web 1 is fed to a folder 2. The folder 2 allows at least the productions A: 2 x 8 pages or optionally B: 1 x 16 pages (both not collected) per full-width paper web, whereby the printing units are equipped with forme cylinders of simple diameter.

Bei Druckwerken mit Formzylindern doppelten Umfanges läßt der Falzapparat die Produktionen C: 4 x 8 Seiten, D: 2 x 16 Seiten oder E: gesammelt 1 x 32 Seiten zu. Mit Seiten sind Buchseiten z. B. mit dem Format 315 mm x 241 mm zu verstehen. Der Falzvorgang wird im folgenden für eine einzige ganzbreite Bahn beschrieben.In the case of printing units with double-cylinder cylinders, the folder allows the productions C: 4 x 8 pages, D: 2 x 16 pages or E: collected 1 x 32 pages. With pages, book pages are z. B. to understand with the format 315 mm x 241 mm. The folding process is described below for a single, very wide web.

Bei der Wahl der Produktionsart A = 2 x 8 Seiten wird die ganzbreite Papierbahn 1 aus dem Wendestangenstuhl 3 mittels einer Wendestange 5 und Papierleitwalzen aus ihrer Lage zwischen den Seitengestellen 4, 6 heraus- und an einem Längsfalztrichter 7 (Trichter 7) und zwei nicht angetriebenen Trichterfalzwalzen 10 vorbeigeführt. Die Papierbahn 1 wird in eine Längsschneideeinrichtung 9 eingeführt, die gegen eine angetriebene Längsperforier- bzw. -rilleinrichtung 11 ausgetauscht werden kann, und läuft dann durch Querperforiereinrichtung 12, angetriebene zweite Zugwalzen 13 zwischen einen Schneidzylinder 14 und einem Punktur- und Falzmesserzylinder 16, im folgenden kurz Falzmesserzylinder 16 genannt. Der Schneidzylinder 14 ist als 2/2 Zylinder ausgeführt und trägt daher zwei sich diametral gegenüberliegende Schneidmesser 19. Der Falzmesserzylinder 16 ist ein 3/2 Zylinder und trägt drei regelmäßig um seinen Umfang verteilt angeordnete, gesteuerte Punktursysteme 22 und gesteuerte Falzmesser 23. Der Falzmesserzylinder 16 wird, wenn die Druckwerke mit Zylindern von "doppeltem Umfang" ausgerüstet sind, zusätzlich als Sammelzylinder ausgeführt. Mit dem Falzmesserzylinder 16 wirkt ein 4/2-Falzklappenzylinder 24 zusammen, der mit vier steuerbaren Falzklappensätzen 26 ausgerüstet ist. Er kann auch zusätzlich mit vier steuerbaren Falzmessern 27 versehen sein.When choosing the production type A = 2 x 8 pages, the full-width paper web 1 is removed from the turning bar chair 3 by means of a turning bar 5 and paper guide rollers from its position between the side frames 4, 6 and on a longitudinal folding former 7 (former 7) and two non-driven ones Funnel folding rollers 10 passed. The paper web 1 is introduced into a longitudinal cutting device 9, which can be exchanged for a driven longitudinal perforating or grooving device 11, and then runs through transverse perforating device 12, driven second pulling rollers 13 between a cutting cylinder 14 and a puncturing and folding knife cylinder 16, in the following called folding knife cylinder 16 for short. The cutting cylinder 14 is designed as a 2/2 cylinder and therefore carries two diametrically opposed cutting knives 19. The folding knife cylinder 16 is a 3/2 cylinder and carries three controlled puncture systems 22 and controlled folding knives that are regularly distributed around its circumference. The folding knife cylinder 16 If the printing units are equipped with "double-circumference" cylinders, they are also designed as collecting cylinders. A 4/2 folding jaw cylinder 24 interacts with the folding blade cylinder 16 and is equipped with four controllable folding jaw sets 26. It can also be provided with four controllable folding blades 27.

Die Falzklappensätze 26 sind in linke und rechte Falzklappen 15, 20 geteilt, die also halbzylinderlang sind. Sämtliche linken 15 und rechten Falzklappen 20 sind getrennt voneinander steuerbar und wahlweise stillsetzbar. Die Steuerung erfolgt so, daß in Produktionsart "A" die linken Falzklappen 15 immer zur Signaturabgabe aus dem linken Signaturstrom zum ersten Transportbandsystem 32 und die rechten Falzklappen 20 immer zur Signaturübergabe aus dem rechten Signaturstrom auf den Greiferzylinder 28 öffnen. Unterhalb des Falzklappenzylinders 24 und mit ihm zusammenwirkend ist ein 312-Greiferzylinder 28 angeordnet. Er weist drei Sätze steuerbare Greiferreihen 31 auf und kann auch zusätzlich steuerbare Falzklappen 29 aufweisen. Zwei aufeinanderfolgende Transportbändersysteme 32, 33 (erstes, zweites) transportieren Signaturen vom Falzklappenzylinder 24 zu einer ersten sog. "Dritte-Falz-Einrichtung" 36, mit der ein Längsfalz erzeugt werden kann. Das erste Bändersystem 32 läuft mit einer Transportgeschwindigkeit die der Umfangsgeschwindigkeit des Falzklappenzylinders 24 entspricht. Das zweite Transportbändersystem 33 weist eine Transportgeschwindigkeit auf, die wesentlich kleiner ist, z. B. um 50 %, als die Umfangsgeschwindigkeit des ersten Falzklappenzylinders 24.The jaw sets 26 are divided into left and right jaws 15, 20, which are therefore half-cylinder long. All left 15 and right folding jaws 20 can be controlled separately from one another and can optionally be stopped. The control takes place in such a way that in production type "A" the left folding jaws 15 always open for signature delivery from the left signature stream to the first conveyor belt system 32 and the right folding jaws 20 always open for signature transfer from the right signature stream to the gripper cylinder 28. A 312 gripper cylinder 28 is arranged below the jaw cylinder 24 and cooperating with it. It has three sets of controllable gripper rows 31 and can also have controllable folding jaws 29. Two successive conveyor belt systems 32, 33 (first, second) transport signatures from the jaw cylinder 24 to a first so-called "third party" te-folding device "36 with which a longitudinal fold can be produced. The first belt system 32 runs at a transport speed that corresponds to the peripheral speed of the folding jaw cylinder 24. The second belt system 33 has a transport speed that is significantly lower, for example by 50% than the peripheral speed of the first jaw cylinder 24.

In der Nähe des Übergabepunktes der Signaturen von Falzklappenzylinder 24 an das erste Bändersystem 32 ist eine im Signaturentakt steuerbare an sich bekannte Signaturweiche 34 angeordnet. Sie ist stillsetzbar. Wenn die Signaturweiche 34 betätigt ist, leitet sie jede zweite Signatur auf die oberen Transportbändersysteme 32, 33. Vom Greiferzylinder 28 führen zwei unmittelbar aufeinander folgende Transportbändersysteme 37 und 38 (drittes und viertes) an einer zweiten "Dritten-Falz"-Einrichtung 39 zur Erzeugung eines Längsfalzes. Das dritte Transportbändersystem 37 läuft mit einer Transportgeschwindigkeit die der Umfangsgeschwindigkeit des Greiferzylinders 28 entspricht. Das vierte Transportbändersystem 38 weist eine Transportgeschwindigkeit auf, die wesentlich kleiner ist, - z. B. um 50 % -, als die Umfangsgeschwindigkeit des Greiferzylinders 28. Das vierte Transportbändersystem 38 ist an der unteren "Dritte-Falz"-Einrichtung 39 befestigt und wird mit ihr gemeinsam verschoben.In the vicinity of the transfer point of the signatures from the folding jaw cylinder 24 to the first belt system 32, a signature switch 34, which is known per se and is controllable in the signature cycle, is arranged. It can be stopped. When the signature switch 34 is actuated, it forwards every second signature to the upper conveyor belt systems 32, 33. Two immediately following conveyor belt systems 37 and 38 (third and fourth) lead from the gripper cylinder 28 to a second “third fold” device 39 for generation of a longitudinal fold. The third conveyor belt system 37 runs at a transport speed which corresponds to the peripheral speed of the gripper cylinder 28. The fourth conveyor belt system 38 has a transport speed that is significantly lower, e.g. B. by 50% - as the peripheral speed of the gripper cylinder 28. The fourth conveyor belt system 38 is attached to the lower "third fold" device 39 and is moved together with it.

Die erste "Dritte-Falz"-Einrichtung 36 und die zweite "Dritte-Falz"-Einrichtung 39 sind in zwei verschieden hohen Ebenen angeordnet.The first "third fold" device 36 and the second "third fold" device 39 are arranged in two different levels.

Die erste "Dritte-Falz"-Einrichtung 36 ist etwa in Höhe des Falzklappenzylinders 24 angeordnet. Seine Ausgangstransportbänder 41 verlaufen parallel zur Rotationsachse des Falzklappenzylinders 24. Die erste "Dritte-Falz"-Einrichtung 36 ist nicht verschiebbar, sie verarbeitet eine linke Teilpapierbahn 17 der in der Längsschneideeinrichtung 9 aufgeschnittenen Papierbahn 1.The first “third fold” device 36 is arranged approximately at the height of the jaw cylinder 24. Its output conveyor belts 41 run parallel to the axis of rotation of the folding jaw cylinder 24. The first “third folding” device 36 cannot be displaced, it processes a left-hand partial paper web 17 of the paper web 1 cut open in the longitudinal cutting device 9.

Unterhalb der Ausgangstransportbänder 41 der oberen "Dritte-Falz"-Einrichtung 36 und links seitlich abgesetzt von dieser ist die zweite (untere) "Dritte-Falz"-Einrichtung 39 angeordnet.The second (lower) "third fold" device 39 is arranged below the exit conveyor belts 41 of the upper "third fold" device 36 and to the left of this.

Die obere "Dritte-Falz"-Einrichtung 36 ist so ausgerichtet, daß ihre Falzlinie und eine Mittellinie der linken Teilpapierbahn 17 auf der gleichen Geraden liegen.The upper "third fold" device 36 is aligned so that its fold line and a center line of the left partial paper web 17 lie on the same straight line.

Die untere "Dritte-Falz"-Einrichtung 39 ist bei der Produktionsart "A" so ausgerichtet, daß ihre Falzlinie und eine Mittellinie einer rechten Teilpapierbahn 18 auf der gleichen Geraden liegen. In dieser Stellung wird die untere "Dritte-Falz"-Einrichtung 39 dann arretiert. Die rechte Teilpapierbahn 18 entsteht zusammen mit der linken Teilpapierbahn 17 beim Aufschneiden der Papierbahn 1. Signaturweiche 34 ist bei Produktionsart "A" stillgesetzt.The lower "third fold" device 39 is oriented in the production type "A" so that its fold line and a center line of a right partial paper web 18 lie on the same straight line. In this position, the lower "third fold" device 39 is then locked. The right partial paper web 18 is formed together with the left partial paper web 17 when the paper web 1 is cut open. Signature switch 34 is stopped in production type "A".

Wird auf die Produktionsart "B" umgestellt, so wird die untere "Dritte-Falz"-Einrichtung 39 entlang einer Parallelen zur Rotationsachse des Falzklappenzylinders 24 verschoben und zwar so weit, bis die Falzlinien von oberer und unterer "Dritte-Falz"-Einrichtung 36, 39 auf einer gemeinsamen vertikalen Ebene liegen. In dieser Stellung wird die untere "Dritte-Falz"-Einrichtung 39 arretiert. Die Signaturweiche 34 ist aktiv, d. h. jede zweite Signatur geht in die oberen Bändersysteme 32, 33.If the switch is made to production type "B", the lower "third fold" device 39 is displaced along a parallel to the axis of rotation of the folding jaw cylinder 24, namely until the fold lines of the upper and lower "third fold" device 36 , 39 lie on a common vertical plane. In this position, the lower "third fold" device 39 is locked. The signature switch 34 is active, i. H. every second signature goes into the upper hinge systems 32, 33.

Obere und untere "Dritte-Falz"-Einrichtung 36 und 39 sind herkömmlicher Bauart. Sie legen die aus. den Signaturen gefalzten Falzprodukte auf ihren Ausgangstransportbändern 41 bzw. 42 ab.Upper and lower "third fold" devices 36 and 39 are of conventional design. You lay them out. the signature folded folding products on their output conveyor belts 41 and 42 respectively.

In der Produktionsstellung A (= 2 x 8 Seiten pro Papierbahn) ist die Längsschneideeinrichtung 9 eingesetzt und die beiden "Dritte-Falz"-Einrichtungen 36, 39 jeweils auf die Mitte der ihr zugeordneten, zu verarbeitenden Teilpapierbahn 17, 18 ausgerichtet. D. h. die untere "Dritte-Falz"-Einrichtung 39 ist so verschoben und anschließend fixiert, daß zwischen beiden gedachten Falzlinien ein bestimmter Abstand erreicht wird, der jeweils eine halbe Papierbahnbreite beträgt. Die linken Falzklappen 15 werden in bekannter Weise so gesteuert, daß jede Klappe 15 an das erste Transportbandsystem 32 abgibt und daß jede rechte Falzklappe 20 an die Greiferreihen 31 des Greiferzylinders 28 die Signaturen abgibt, von wo sie anschließend an das dritte und vierte Transportbändersystem 37, 38 übergegeben werden. Das vierte Transportbändersystem 38 transportiert die einmal quergefalzten Signaturen in die untere "Dritte-Falz-"Einrichtung 39 wo die Signaturen des unteren Signaturenstromes ihren ersten Längsfalz erhalten und damit das fertige Falzprodukt entstanden ist, das auf den Ausgangstransportbändern 42 abgelegt wird. Sie haben die Form wie in Fig. 4A dargestellt. Vom Falzklappenzylinder 24 werden einmal quergefalzte Signaturen - wie oben beschrieben - an das erste Transportbändersystem 32 und von da an das zweite zweite Transportbändersystem 33 abgegeben. Das zweite Transportbändersystem 33 transportiert die einmal quergefalzten Signaturen in die obere "Dritte-Falz-"Einrichtung 36 wo die Signaturen des oberen Signaturstromes ihren ersten Längsfalz erhalten zum gewünschten achtseitigen Falzprodukt und auf den Ausgangstransportbändern 41 ausgelegt werden.In the production position A (= 2 x 8 pages per paper web), the longitudinal cutting device 9 is inserted and the two “third-fold” devices 36, 39 are each aligned with the center of the associated partial paper web 17, 18 to be processed. I.e. the lower “third fold” device 39 is displaced and then fixed in such a way that a certain distance is reached between the two imaginary fold lines, which is in each case half a paper web width. The left folding flaps 15 are controlled in a known manner so that each flap 15 delivers to the first conveyor belt system 32 and that each right folding flap 20 delivers the signatures to the gripper rows 31 of the gripper cylinder 28, from where it then passes to the third and fourth conveyor belt systems 37, 38 are handed over. The fourth conveyor belt system 38 transports the once cross-folded signatures into the lower "third fold" device 39 where the signatures of the lower signature stream receive their first longitudinal fold and thus the finished folded product has been created, which is stored on the output conveyor belts 42. They have the shape as shown in Fig. 4A. Signatures folded once are folded from the folding jaw cylinder 24 - as described above - to the first conveyor belt system 32 and from there to the second second conveyor belt system 33. The second conveyor belt system 33 transports the once folded signatures into the upper "third fold" device 36 where the signatures of the upper signature stream receive their first longitudinal fold for the desired eight-sided fold product and are laid out on the output conveyor belts 41.

In der Produktionsstellung B (= 1 x 16 Seiten pro Papierbahn) wird die Längsschneideeinrichtung 9 gegen die Längsperforier- bzw. Rilleinrichtung 11 ausgetauscht. Die untere "Dritte-Falz"-Einrichtung 39 wird so zur festen oberen "Dritte-Falz"-Einrichtung 36 verschoben, daß beide Falzlinien in einer gemeinsamen senkrechten Ebene liegen. Die Papierbahn 1 wird nicht seitlich neben dem Längsfalztrichter 7 vorbeigeführt, sondern läuft über den Längsfalztrichter 7. Die Falzmesser 23 sind so gesteuert, daß die Signaturen in die linken Falzklappen 15 des Falzklappenzylinders 24 übergeben werden. Die rechten Falzklappen 20 werden stillgesetzt. Die linken Falzklappen 15 werden gesteuert wie bei Produktionsart "A". Ebenso ist der Transport über die Transportbändersysteme 32, 33, 37, 38 und die Verarbeitung in den "Dritte-Falz"-Einrichtungen 36, 39 gleich. Die mittels des Längsfalztrichters 7 und Trichterfalzwalzenpaar 10 längsgefalzte aufgeschnittene oder nicht aufgeschnittene Bahn 1 wird von dem Zugwalzenpaar 8 gezogen, anschließend in der Längsperforier- bzw. Rilleinrichtung 11 perforiert bzw. gerillt, anschließend von den Schneidmessern 19 des Schneidzylinders 14 in einmal längsgefalzte Signaturen geschnitten. Die steuerbaren Punktursysteme 22 nadeln die Signaturen auf den Punktur- und Falzmesserzylinder 16 auf. Die gesteuerten Falzmesser 23 drücken die Signaturen zum ersten Querfalz in die linken Falzklappen 15 des ersten Falzklappenzylinders 24. Die linken Falzklappen 15 werden so gesteuert, daß die erste und dritte Klappe 15 an das erste Transportbandsystem 32, und die zweite und vierte linke Falzklappe 15 an den Greiferzylinder 28 abgibt. Die Signaturweiche 34 kann nun wahlweise in folgende Arbeitsstellungen gebracht werden:

  • I: An- und Abstellen der Signaturweiche 34 im Takt der ankommenden Signaturen. Dies hat zur Folge, daß jede zweite Signatur an das erste Transportbändersystem 32 abgegeben wird. Die restlichen werden auf den Greiferzylinder 28 übergeben.
  • 11: Signaturweiche 34 dauernd an den Falzklappenzylinder 24 angestellt. Sämtliche Signaturen werden an das erste Transportbändersystem 32 übergeben. 111: Signaturweiche 34 dauernd von Falzklappenzylinder 24 abgestellt. Sämtliche Signaturen werden an den Greiferzylinder 28 abgegeben und damit an das dritte Transportbändersystem.
In the production position B (= 1 x 16 pages per paper web), the longitudinal cutting device 9 is exchanged for the longitudinal perforating or grooving device 11. The lower "third fold" device 39 is moved to the fixed upper "third fold" device 36 such that both fold lines lie in a common vertical plane. The paper web 1 is not passed laterally next to the longitudinal folding former 7, but runs over the longitudinal folding former 7. The folding blades 23 are controlled so that the signatures are transferred into the left folding jaws 15 of the folding jaw cylinder 24. The right jaws 20 are stopped. The left jaws 15 are controlled as in production type "A". Likewise, the transport via the conveyor belt systems 32, 33, 37, 38 and the processing in the "third-fold" devices 36, 39 are the same. The one which is longitudinally folded open by means of the longitudinal folding former 7 and a pair of former folding rollers 10 or non-cut web 1 is pulled by the pair of pulling rollers 8, then perforated or grooved in the longitudinal perforating or grooving device 11, then cut by the cutting knives 19 of the cutting cylinder 14 into once folded signatures. The controllable puncture systems 22 pin the signatures onto the puncture and folding knife cylinder 16. The controlled folding knives 23 press the signatures for the first transverse fold into the left folding jaws 15 of the first folding jaw cylinder 24. The left folding jaws 15 are controlled so that the first and third jaws 15 are in contact with the first conveyor belt system 32, and the second and fourth left folding jaws 15 delivers the Gre i fer cylinder 28. The signature switch 34 can now optionally be brought into the following working positions:
  • I: Turning the signature switch 34 on and off in time with the incoming signatures. As a result, every second signature is given to the first conveyor belt system 32. The rest are transferred to Gre i fer cylinder 28.
  • 11: Signature switch 34 permanently set to the jaw cylinder 24. All signatures are transferred to the first conveyor belt system 32. 111: Signature switch 34 permanently parked by jaw cylinder 24. All signatures are delivered to the gripper cylinder 28 and thus to the third conveyor belt system.

Durch das obere Transportbändersystem 32, 33 werden die Signaturen in die obere "Dritte-Falz"-Einrichtung 36 transportiert, wo sie den dritten Falz, d. h. den zweiten Längsfalz, zum fertigen Produkt erhalten. In der Produktionsart "B" laufen das zweite und das vierte Transportbändersystem 33, 38 mit ca. 50 % der Transportgeschwindigkeit der ersten und dritten Transportbändersysteme 32, 37.Through the upper conveyor belt system 32, 33, the signatures are transported into the upper "third fold" device 36, where they are the third fold, i. H. received the second longitudinal fold for the finished product. In production type "B", the second and fourth conveyor belt systems 33, 38 run at approximately 50% of the transport speed of the first and third conveyor belt systems 32, 37.

Die gesteuerten Greiferreihen 31 des Greiferzylinders 28 greifen die auf dem Falzklappenzylinder 24 nach der Signaturweiche 34 verbliebenen Signaturen und übernehmen sie auf den Greiferzylinder 28 und übergeben sie an das dritte Transportbändersystem 37. Dieses übergibt die Signaturen an das vierte 38, das mit ca. 50 % der Transportgeschwindigkeit des dritten Transportbändersystems 37 läuft. Es transportiert die Signaturen in die untere "Dritte-Falz"-Einrichtung 39, wo sie den dritten Falz, d. h. den zweiten Längsfalz, zum fertigen Falzprodukt erhalten.The controlled gripper rows 31 of the gripper cylinder 28 grip the signatures remaining on the jaw cylinder 24 after the signature switch 34 and transfer them to the gripper cylinder 28 and transfer them to the third conveyor belt system 37. The latter transfers the signatures to the fourth 38, which with approx. 50% the transport speed of the third conveyor belt system 37 runs. It transports the signatures into the lower "third fold" device 39, where it carries the third fold, i.e. the third fold. H. received the second longitudinal fold for the finished folded product.

In den Arbeitsstellungen II und III der Signaturweiche 34 laufen die vier Bändersysteme 32, 33, 37, 38 mit gleicher Transportgeschwindigkeit, die jeweils der Umlaufgeschwindigkeit des Falzklappenzylinders 24 entspricht.In working positions II and III of the signature switch 34, the four belt systems 32, 33, 37, 38 run at the same transport speed, which corresponds to the rotational speed of the jaw cylinder 24.
