Description

Die Erfindung betrifft eine Vorrichtung an einem Falzklappenzylinder zur Übernahme und zum Weitertransport der zwischen Falzklappenzylinder und Falzmesserzylinder mit einem Querfalz versehenen Falzprodukte durch eine umlaufende Transportvorrichtung.The invention relates to a device on a folding jaw cylinder for taking over and further transporting the folding products provided with a transverse fold between the folding jaw cylinder and the folding knife cylinder by means of a rotating transport device.

Aus der DE-AS 2136227 ist es beispielsweise bekannt, gefaltete Papierprodukte mittels eines Trennteiles wieder zu öffnen, um z.B. Beilagen in das Falzprodukt einfügen zu können. Für das Wiederöffnen von Falzprodukten wird üblicherweise eine separate Vorrichtung benötigt, was die Gerätekosten und die sogenannte Weiterverarbeitung allgemein verteuert bzw. verumständlicht.From DE-AS 2136227 it is known, for example, to reopen folded paper products by means of a separating part in order, for example, To be able to insert inserts into the folded product. A separate device is usually required for the reopening of folded products, which generally increases the cost of equipment and the so-called further processing.

Aufgabe der Erfindung ist es, eine Vorrichtung aufzuzeigen, mit der ohne die Verwendung solcher Vorrichtungen zum Öffnen von gefalzten Produkten bzw. Teilprodukten die Möglichkeit geboten wird, die Falzprodukte weiterzuverarbeiten, beispielsweise Teilprodukte ineinander zu sammeln, Beilagen anzufügen oder die Falzprodukte auszulegen.The object of the invention is to provide a device which, without the use of such devices for opening folded products or partial products, offers the possibility of further processing the folded products, for example collecting partial products into one another, adding inserts or laying out the folded products.

Die Erfindung geht aus von einem herkömmlichen Falzapparat, wie er beispielsweise aus dem DE-Patent 3143242 bekannt ist, der einen Falzklappenzylinder und einen an diesen angestellten Falzmesserzylinder, der auch gleichzeitig Sammelzylinder sein kann, umfasst. Bekanntlich wird hierbei der Falz dadurch gebildet, dass die auf dem Falzmesserzylinder liegenden Bogen oder Bogenpakete durch ein Falzmesser, das steuerbar am Falzmesserzylinder angeordnet ist, in die geöffnete Falzklappe im Falzklappenzylinder gestossen werden. Über eine umlaufende Transportvorrichtung, z.B. ein Schaufelrad, erfolgt dann die Entnahme der Falzprodukte aus dem Falzapparat.The invention is based on a conventional folding apparatus, as is known, for example, from DE patent 3143242, which comprises a folding jaw cylinder and a folding blade cylinder which is attached to it and which can also be a collecting cylinder at the same time. As is known, the fold is formed by pushing the sheets or packages of sheets lying on the folding knife cylinder into the open folding jaw in the folding jaw cylinder by a folding knife which is controllably arranged on the folding knife cylinder. Via a rotating transport device, e.g. a paddle wheel, the folding products are then removed from the folder.

Die der Erfindung zugrunde liegende Aufgabe wird dadurch gelöst, dass die mit Mitnehmern versehene umlaufende Transportvorrichtung in dem etwa keilförmigen Bereich oberhalb der Übergabestelle des Falzproduktes von dem Falzmesserzylinder zu dem Falzklappenzylinder angeordnet ist, dass die Mitnehmer so an der Transportvorrichtung positioniert sind, dass jeweils ein Mitnehmer nach dem Einstossen des Falzproduktes in die Falzklappe des Falzklappenzylinders seitlich zwischen die beiden Hälften, die noch auf dem Falzmesserzylinder aufliegen, in den keilförmigen Bereich eingreifen und dass nach Freigabe der Falzprodukte durch die Falzklappen die Mitnehmer die Falzprodukte von dem Falzklappenzylinder abheben und weitertransportieren.The object on which the invention is based is achieved in that the circumferential transport device provided with drivers is arranged in the approximately wedge-shaped area above the transfer point of the folded product from the folding knife cylinder to the folding jaw cylinder in such a way that the drivers are positioned on the transport device in such a way that one driver each After the folding product has been pushed into the folding jaw of the folding jaw cylinder, engage laterally between the two halves that are still resting on the folding knife cylinder in the wedge-shaped area and that after the folding products have been released by the folding jaws, the drivers lift the folding products off the folding jaw cylinder and transport them on.

Die erfindungsgemässe Vorrichtung bietet den Vorteil, dass vor der Zusammenführung der beiden Hälften der Falzprodukte Mitnehmer, beispielsweise in Form von Messern oder Stäben, nach Bildung des Falzes bzw. des Falzrückens in den Falzklappen seitlich eingeführt werden, mit deren Hilfe die Falzprodukte aus den Falzklappen bzw. von dem Falzmesserzylinder entnommen und weitertransportiert werden können; gegebenenfalls nach entsprechender Spreizung der beiden Hälften der Falzprodukte können dann in einfacher Weise Beilagen angefügt oder Falzprodukte zusammengetragen werden. Ebenfalls ist es möglich, unter Herausziehen der Mitnehmer die Falzprodukte schuppenförmig oder paketförmig abzulegen. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen jeweils schematisch:

The device according to the invention has the advantage that, before the two halves of the folded products are brought together, drivers, for example in the form of knives or bars, are inserted laterally in the fold flaps after the fold or fold back has been formed, with the aid of which the fold products from the fold flaps or can be removed from the folding knife cylinder and transported further; if necessary after appropriate spreading of the two halves of the folded products, inserts can then be added in a simple manner or folded products can be collected. It is also possible to deposit the folded products in the form of a scale or a packet while pulling out the drivers. Further developments of the invention result from the subclaims and from the description in conjunction with the drawings. Each of these shows schematically:

In Fig. 1 sind ein Falzmesserzylinder 1 und ein Falzklappenzylinder 2 angedeutet, wie sie üblicherweise in herkömmlichen Falzapparaten verwendet werden. Der Falzmesserzylinder 1 kann gleichzeitig als Sammelzylinder Verwendung finden. Am Falzmesserzylinder 1 sind steuerbare Falzmesser 3 und am Falzklappenzylinder 2 steuerbare Falzklappen 4 vorgesehen, mit deren Hilfe ein oder mehrere aufeinanderliegende Bogen 5 mit einem Querfalz versehen werden können. Bekanntlich wird zur Erzeugung dieses Querfalzes an einer Falzlinie 6 das Falzmesser 3 zeitgerecht in die zugehörige Falzklappe 4 gestossen, die nach oder während der Zurücknahme des Falzmessers 3 geschlossen wird, um den Falz zu bilden und das Falzprodukt 5 festzuhalten.In Fig. 1, a folding knife cylinder 1 and a folding jaw cylinder 2 are indicated, as they are usually used in conventional folders. The folding knife cylinder 1 can also be used as a collecting cylinder. Controllable folding blades 3 are provided on the folding knife cylinder 1 and folding jaws 4 controllable on the folding jaw cylinder 2, by means of which one or more sheets 5 lying one on top of the other can be provided with a transverse fold. As is known, in order to produce this transverse fold on a folding line 6, the folding knife 3 is pushed in time into the associated folding flap 4, which is closed after or during the withdrawal of the folding knife 3 in order to form the fold and to hold the folded product 5 in place.

In dem dreieckförmigen Raum A etwa oberhalb der Übergabestelle der Falzprodukte 5 an den Falzklappenzylinder 2, ist das untere Ende einer umlaufenden Endlostransportvorrichtung, z.B. eines Endloszahnriemens 7, an dessen Stelle auch eine Kette verwendet werden kann, positioniert. An dem Endloszahnriemen 7 sind an bestimmten Stellen, vorzugsweise in gleichen Abständen, Mitnehmer 8 befestigt. Vorzugsweise ist beidseitig der Falzprodukte 5, beispielsweise in der Ebene der Stirnflächen der Zylinder 1, 2 oder parallel dazu, jeweils ein Endloszahnriemen 7 angeordnet. Der Endloszahnriemen 7 wird jeweils um ein oberes Umlenkrad 9 und ein unteres in dem genannten keilförmigen bzw. dreieckförmigen Bereich A positioniert. Parallel zum oberen Bereich des Endloszahnriemens 7 verläuft eine weitere umlaufende Transportvorrichtung, beispielsweise ein weiterer Endloszahnriemen 11, an dem ebenfalls Mitnehmer 12 angeordnet sind.In the triangular space A, approximately above the transfer point of the folding products 5 to the folding jaw cylinder 2, the lower end of a rotating endless transport device, e.g. an endless toothed belt 7, in its place a chain can be used. Carriers 8 are fastened to the endless toothed belt 7 at certain points, preferably at equal intervals. An endless toothed belt 7 is preferably arranged on both sides of the folded products 5, for example in the plane of the end faces of the cylinders 1, 2 or parallel thereto. The endless toothed belt 7 is positioned in each case around an upper deflection wheel 9 and a lower one in said wedge-shaped or triangular region A. Another circumferential transport device, for example a further endless toothed belt 11, on which drivers 12 are also arranged, runs parallel to the upper region of the endless toothed belt 7.

Wie Fig. 1 'n Verbindung mit Fig. 2 erkennen lässt, werden der oder die auf dem Falzmesserzylinder liegenden Bogen bzw. Falzprodukte 5 durch jeweils ein Falzmesser 3 in die zugehörige Falzklappe 4 gestossen, während sich die Zylinder 1, 2 gegenläufig drehen. Dadurch entsteht jeweils kurz nach dem Einstossvorgang ein durch die beiden Hälften 5a und 5b der Falzprodukte 5 begrenzter Keil bzw. dreieckförmiger Raum A. Zu dieser Zeit werden die Falzprodukte 5 an der Falzlinie 6 noch in den Falzklappen 4 gehalten. Erfindungsgemäss greifen zu diesem Zeitpunkt jeweils vorzugsweise von beiden Seiten die an dem Endloszahnriemen 7 befestigten Mitnehmer 8 unterhalb der Falzlinie 6 zwischen die beiden Hälften 5a und 5b der Falzprodukte 5 ein. Die Geschwindigkeit der Endloszahnriemen 7 kann maximal der der Umfangsgeschwindigkeit der Zylinder 1, 2 entsprechen, liegt jedoch in der Praxis etwas darunter, vorzugsweise etwa um 20%. Nach dem Einführen der Mitnehmer 8 in den dreieckförmigen Raum A, einem sogenannten «Zwickel», ergibt sich der besonders aus Fig. 2 hervorgehende Übernahmevorgang des Falzproduktes 5. Vorzugsweise, nachdem die Mitnehmer 8 in den Bereich A eingeführt wurden, öffnen sich die Falzklappen 4, so dass die Falzprodukte 5 jeweils freigegeben werden. Gleichzeitig wird mit Hilfe eines zusätzlich vorgesehenen Abstreifers 13 bewirkt, dass die Falzprodukte 5 aus der Falzklappe 4 herausgehoben werden. Zusätzlich unterstützt die Zentrifugalkraft diesen Herausführungsvorgang. Nunmehr «fliegen» die Falzprodukte mit der Falzlinie 6 voraus, etwa in tangentialer Richtung, bezogen auf den Falzklappenzylinder 2. Die Geschwindigkeit der Falzprodukte 5 nimmt jetzt ab, so dass nach einer gewissen Zeit die Mitnehmer 8 sich bis zur Falzlinie 6 vorschieben. Dieser Verlauf ist an den Falzexemplaren 5', 5", 5"' in Fig. 2 angedeutet. Der Mitnehmer 8 kommt in der Position des Exemplares 5"' an der Innenseite des Falzes 6 zu liegen, so dass von diesem Zeitpunkt an der Mitnehmer 8 die Führung und den Weitertransport des Falzexemplares 5"' übernimmt. Von nun an hängen die Falzexemplare 5"' an den beiden seitlich eingeführten Mitnehmern. Da an dem Übernahmeendloszahnriemen 11 gleichartige Mitnehmer 12 angeordnet sind, können die Falzexemplare 5 von den Mitnehmern 12 während deren Aufwärtsbewegung übernommen werden. Selbstverständlich können von diesem Zeitpunkt an die Mitnehmer 8 der Endloszahnriemen 7 wieder aus den Falzexemplaren 5 herausgezogen werden.As can be seen from FIG. 1 'n in connection with FIG. 2, the sheet or fold products 5 lying on the folding knife cylinder are pushed into the associated folding flap 4 by a folding knife 3 while the cylinders 1, 2 rotate in opposite directions. This results in a wedge or triangular space A delimited by the two halves 5a and 5b of the folded products 5 shortly after the pushing-in process. At this time, the folded products 5 are still held in the folding flaps 4 on the folding line 6. According to the invention, the catches 8 attached to the endless toothed belt 7 engage below the fold line 6 between the two halves 5a and 5b of the fold products 5 from both sides at this time. The speed of the endless toothed belts 7 can at most correspond to the circumferential speed of the cylinders 1, 2, but in practice is somewhat less, preferably around 20%. After the carriers 8 have been introduced into the triangular space A, a so-called “gusset”, the takeover process of the folded product 5, which is particularly apparent from FIG. 2, results. Preferably, after the carriers 8 have been introduced into the region A, the folding flaps 4 open , so that the folding products 5 are released in each case. At the same time, an additionally provided scraper 13 causes the folding products 5 to be lifted out of the folding flap 4. In addition, the centrifugal force supports this extraction process. Now the folding products “fly” ahead with the folding line 6, for example in a tangential direction, with respect to the folding jaw cylinder 2. The speed of the folding products 5 now decreases, so that after a certain time the drivers 8 advance to the folding line 6. This course is indicated on the folded copies 5 ', 5 ", 5"' in FIG. 2. The driver 8 comes to rest in the position of the copy 5 "'on the inside of the fold 6, so that from this point on the driver 8 takes over the guidance and the further transport of the fold copy 5"'. From now on, the folded copies 5 "'will hang on the two laterally inserted drivers. Since identical drivers 12 are arranged on the take-over endless toothed belt 11, the folded copies 5 can be taken over by the drivers 12 during their upward movement the endless toothed belt 7 can be pulled out of the folded copies 5 again.

Fig. 3 zeigt eine Variante der Ausführungsform gemäss Fig. 1 und 2, bei der der die Falzexemplare 5 von dem Falzklappenzylinder 2 übernehmende Endloszahnriemen 14, der um Umlenkräder 15, 16 geführt ist, partiell um den Falzklappenzylinder 2 geführt ist. Der Vorgang zum Einfügen der Mitnehmer 17 an dem Zahnriemen 14 im keilförmigen Bereich A ist identisch mit dem zuvor im Zusammenhang mit Fig. 1 und 2 beschriebenen Vorgang. Die Falzexemplare 5 werden lediglich durch die oder mit den Mitnehmern 17 noch teilweise um den Falzklappenzylinder 2 geführt. Anschliessend erfolgt die Übergabe der Falzprodukte am Mitnehmer 18 eines nicht näher dargestellten weiteren Transportsystems.3 shows a variant of the embodiment according to FIGS. 1 and 2, in which the endless toothed belt 14 taking over the folding copies 5 from the folding jaw cylinder 2, which is guided around deflection wheels 15, 16, is partially guided around the folding jaw cylinder 2. The process for inserting the drivers 17 on the toothed belt 14 in the wedge-shaped area A is identical to the process previously described in connection with FIGS. 1 and 2. The folded copies 5 are only partially guided by or with the drivers 17 around the folding jaw cylinder 2. The folded products are then transferred to the driver 18 of a further transport system, not shown in detail.

In Fig. 4 ist angedeutet, dass ein Endloszahnriemen 19 mit Mitnehmern 20, an dessen Stelle auch eine Kette verwendet werden könnte, vorzugsweise etwa in der Winkelhalbierenden angeordnet ist, wobei die nicht näher bezeichnete untere Umlenkrolle des Endloszahnriemens 19 möglichst weit in den Bereich A, das heisst in Richtung Übergabestelle der Falzprodukte von dem Falzmesserzylinder 1 zu dem Falzklappenzylinder 2, angeordnet werden sollte. Auch hier wird wiederum beim Übergabevorgang der Falzprodukte 5 an die Mitnehmer 20 mittels eines Abstreifers 21 für eine sichere Herausführung der Falzexemplare 5 aus den Falzklappen des Falzklappenzylinders 2 gesorgt.4 it is indicated that an endless toothed belt 19 with drivers 20, in whose place a chain could also be used, is preferably arranged approximately in the bisector, the lower deflection roller of the endless toothed belt 19, which is not described in greater detail, as far as possible into the area A, that is, should be arranged in the direction of the transfer point of the folding products from the folding knife cylinder 1 to the folding jaw cylinder 2. Here too, during the transfer process of the folding products 5 to the drivers 20, a scraper 21 ensures that the folding copies 5 are guided safely out of the folding jaws of the folding jaw cylinder 2.

Wie bereits erwähnt, sollten vorzugsweise beidseitig der Falzexemplare 5 umlaufende Transportvorrichtungen verwendet werden. Gemäss Fig. 5 sind beidseitig schräggestellte Transportvorrichtungen in Form von Endloszahnriemen 19, 19' eingesetzt. Beide Vorrichtungen sind identisch, weshalb die Elemente an der linken Seite lediglich durch ein Apostroph von den an der rechten Seite unterschieden sind. An dem Endloszahnriemen 19 sind Mitnehmer 20 angeordnet, die durch eine mechanische Steuervorrichtung im Bereich A seitlich zwischen die beiden Hälften 5a, 5b des Falzexemplares 5 eingeschoben werden. Beispielsweise können diese Vorrichtungen aus Kurvenscheiben 23 bestehen, die mit einem entsprechenden Steuerbereich 24, beispielsweise einer Nut, ausgestattet sind. Dadurch können die in dem Steuerbereich 24 geführten Mitnehmer 20 zu dem Zeitpunkt einwärts geschoben werden, zu dem die Falzexemplare 5 in den Falzklappen 4 (Fig. 1) gehalten werden, das heisst, wenn durch die Hälften 5a, 5b der keilförmige Bereich A gebildet wird. Wie aus Fig. 5 hervorgeht, wird durch die Schrägstellung der Zahnriemen 19, 19' automatisch erreicht, dass die Mitnehmer 20 bzw. 20' aus den Falzexemplaren 5 bzw. 5', 5" herausgezogen werden. Um die Falzexemplare 5, 5' usw. in einer gewünschten Richtung zu führen, können beidseitig Führungsbleche oder ähnliche Führungsvorrichtungen 22, 22' angebracht werden.As already mentioned, peripheral transport devices should preferably be used on both sides of the folded copies 5. 5, inclined transport devices in the form of endless toothed belts 19, 19 'are used on both sides. Both devices are identical, which is why the elements on the left are only distinguished from those on the right by an apostrophe. Carriers 20 are arranged on the endless toothed belt 19 and are inserted laterally between the two halves 5a, 5b of the folded copy 5 by a mechanical control device in area A. For example, these devices can consist of cams 23, which are equipped with a corresponding control area 24, for example a groove. As a result, the drivers 20 guided in the control area 24 can be pushed inwards at the point in time at which the folding copies 5 are held in the folding jaws 4 (FIG. 1), that is to say when the wedge-shaped area A is formed by the halves 5a, 5b . As can be seen from FIG. 5, the inclined position of the toothed belts 19, 19 'automatically ensures that the drivers 20 and 20' are pulled out of the folded copies 5 and 5 ', 5 ". In order to remove the folded copies 5, 5', etc to guide in a desired direction, guide plates or similar guide devices 22, 22 'can be attached on both sides.

Bei der Ausführungsform der Erfindung gemäss Fig. 6 sind die beidseitig der Falzexemplare 5, 5', 5", 5"' angeordneten umlaufenden Transportvorrichtungen in Form von Ketten oder Bändern 25 parallel gestellt. Deshalb müssen die Mitnehmer 26 im Bereich A durch zusätzliche Steuervorrichtungen 27 zeitgerecht eingeschoben werden. Dies kann dadurch geschehen, dass beispielsweise die Mitnehmer 26 durch Steuervorrichtungen 27 in Form von pneumatischen, hydraulischen oder magnetischen Elementen nach innen geschoben werden. Durch nicht dargestellte, umgekehrt wirkende Vorrichtungen können dann nach Abgabe der Falzprodukte an ein weiteres System die Mitnehmer 26 jeweils wieder nach aussen gezogen werden.In the embodiment of the invention according to FIG. 6, the circumferential transport devices in the form of chains or belts 25 arranged on both sides of the folded copies 5, 5 ', 5 ", 5"' are parallel. Therefore, the drivers 26 in area A must be inserted in time by additional control devices 27. This can be done in that, for example, the drivers 26 are pushed inwards by control devices 27 in the form of pneumatic, hydraulic or magnetic elements. By means of devices, not shown, acting in reverse, the drivers 26 can then be pulled outwards again after the folded products have been delivered to a further system.

Fig. 7 zeigt eine Anordnung, bei der die Übernahme der Falzprodukte 5 und deren Weitertransport durch ein verhältnismässig schräggestelltes Transportsystem in Form eines umlaufenden Zahnriemens 28 an dessen oberem Trum erfolgen.Fig. 7 shows an arrangement in which the take-over of the folded products 5 and their further transport take place by means of a relatively inclined transport system in the form of a rotating toothed belt 28 on its upper run.

Eine weitere vorteilhafte Vorrichtung ergibt sich aus den Figuren 8 und 9. Hier sind wiederum beidseitig der zu übernehmenden Falzprodukte 5, 5', 5", 5"' umlaufende Transportvorrichtungen in Form von Ketten oder Bändern 28 angeordnet, an denen jeweils Mitnehmer 30 befestigt sind. Lediglich der untere Teil der Zahnriemen 28, 28' ist angedeutet, in dem die Übernahme der Falzprodukte 5 in den Bereich A erfolgt. Die Position des Falzklappenzylinders 2 in Fig. 8 ist bei «C» angedeutet. An dem Übergabebereich A werden die Zahnriemen 28, 28' um Umlenkräder 29, 29' geführt, wobei die Mitnehmer 30, 30' das zu übernehmende Falzprodukt 5 beim Umlaufen um die Umlenkräder 29, 29' aufnehmen. Der Schwenkbogen der Mitnehmer 30, 30' begrenzt den Abstand des Umlenkrades 29 zu dem Falzklappenzylinder 2, der durch die Linie C angedeutet ist. Wie Fig. 8 zu entnehmen ist, wird bei dem Umlaufen des Zahnriemens 28 um das Rad 29 jeweils ein Mitnehmer 30 nach innen in die noch auseinanderstehenden Hälften 5a, 5b des Falzproduktes 5 vorgenommen, das, wie bereits im Zusammenhang mit der Beschreibung von Fig. 1 dargelegt wurde, zu diesem Zeitpunkt noch in den Falzklappen gehalten wird. Nach anschliessender Freigabe der Falzprodukte 5 aus den Falzklappen erfolgt der Weitertransport der Falzexemplare 5, 5', 5", 5"' durch die Mitnehmer 30, 30' der beidseitig angeordneten Endloszahnriemen 28, 28'.Another advantageous device results from FIGS. 8 and 9. Here, in turn, the transport products in the form of chains or belts 28 are arranged on both sides of the folded products 5, 5 ', 5 ", 5"' to which carriers 30 are attached. Only the lower part of the toothed belts 28, 28 'is indicated, in which the folding products 5 are taken over into area A. The position of the jaw cylinder 2 in Fig. 8 is indicated at "C". At the transfer area A, the toothed belts 28, 28 'are guided around deflection wheels 29, 29', the drivers 30, 30 'receiving the folded product 5 to be taken over as they circulate around the deflection wheels 29, 29'. The swivel arc of the drivers 30, 30 'limits the distance between the deflection wheel 29 and the jaw cylinder 2, which is indicated by the line C. As can be seen in FIG. 8, when the toothed belt 28 rotates around the wheel 29, a driver 30 is made inward into the still separated halves 5a, 5b of the folded product 5, which, as already described in connection with the description of FIG. 1 was set out at this time is still held in the jaws. After the subsequent release of the folding products 5 from the folding flaps, the folding copies 5, 5 ', 5 ", 5"' are transported further by the drivers 30, 30 'of the endless toothed belts 28, 28' arranged on both sides.

Fig. 9 zeigt einen Schnitt entlang der Linie 1-11 und lässt erkennen, dass die Mitnehmer 30 über Befestigungsbolzen 31 in der beispielsweise als Gliederkette ausgebildeten umlaufenden Transportvorrichtung 28 fixiert sein können. Die Kette 28 kann jeweils in Führungen 32 bzw. 33 für die innere und äussere Bahn angeordnet sein. Damit ergibt sich eine exakte Führung der Falzexemplare 5.FIG. 9 shows a section along the line 1-11 and reveals that the drivers 30 can be fixed via fastening bolts 31 in the rotating transport device 28, which is designed, for example, as a link chain. The chain 28 can be arranged in guides 32 and 33 for the inner and outer web. This results in an exact guidance of the folded copies 5.

Wie aus Fig. 8 ersichtlich, wird durch die Verschwenkbewegung der Mitnehmer 30 um das Rad 29 ein verhältnismässig grosser Platz benötigt, der unter Umständen die erforderliche Nähe des Umlenkrades 29 zum Falzklappenzylinder nicht zulässt. Um diesen Abstand zu verringern, beispielsweise von C bis zur Linie B in Fig. 8, kann eine vorteilhafte Führung für den Endlosriemen bzw. für die Kette 34 gemäss Fig. 10 und 11 verwendet werden. Bei dieser Führung wird die in Fig. 8 angedeutete Schwenkbewegung der dortigen Mitnehmer 30 und des Umlenkrades 29 vermieden. Hier erfolgt quasi eine Linearverschiebung der Mitnehmer 35 von innen nach aussen bei einer Herumführung um das Umlenkrad 47. An der Kette 34 sind die Mitnehmer 35 über einen Schlitten 36 befestigt, der in Kugellagern 37 in zwei Führungsschienen 40, 41 läuft. Die Kugellager 37 sitzen auf Bolzen 38, 39, von denen der Bolzen 39 in vorteilhafter Weise gleichzeitig die Verlängerung einer Hülse der Führungskette 34 sein kann.As can be seen from FIG. 8, the pivoting movement of the drivers 30 around the wheel 29 requires a relatively large space which, under certain circumstances, does not permit the required proximity of the deflection wheel 29 to the jaw cylinder. In order to reduce this distance, for example from C to line B in FIG. 8, an advantageous guide for the endless belt or for the chain 34 according to FIGS. 10 and 11 can be used. With this guidance, the pivoting movement indicated in FIG. 8 of the driver 30 there and of the deflection wheel 29 is avoided. Here, the carriers 35 are quasi linearly displaced from the inside to the outside when they are guided around the deflection wheel 47. The carriers 35 are fastened to the chain 34 by means of a slide 36 which runs in ball bearings 37 in two guide rails 40, 41. The ball bearings 37 are seated on bolts 38, 39, of which the bolt 39 can advantageously also be the extension of a sleeve of the guide chain 34.

Fig. 10 lässt erkennen, dass bei einem Transport der Kette 34 in Pfeilrichtung die Mitnehmer 35 stets waagrecht verbleiben, wenn sie gegen den Uhrzeigersinn um das Umlenkrad 47 herumgeführt werden, so dass sie auf der rechten Seite im Bereich A in die noch auseinanderstehenden Hälften 5a, 5b eines Falzproduktes 5 eingeführt werden können und nach Übernahme des Falzproduktes 5 von dem Falzklappenzylinder bzw. dem Falzmesserzylinder 1 den Weitertransport übernehmen können.10 shows that when the chain 34 is transported in the direction of the arrow, the drivers 35 always remain horizontal if they are guided counterclockwise around the deflection wheel 47, so that they are on the right side in area A into the halves 5a that are still apart , 5b of a folding product 5 can be introduced and, after taking over the folding product 5 from the folding jaw cylinder or the folding knife cylinder 1, can take over the further transport.

Letztlich zeigt Fig. 12 eine weitere Variante. Hier sind an einen Bügel 42, dessen Breite, wie durch Doppelpfeile angedeutet, beispielsweise durch eine teleskopartige Ausbildung den Breiten der Falzprodukte 5 angepasst werden kann, zwei einschwenkbare Arme 43, 44 befestigt. Durch seitlich angeordnete Steuermittel, beispielsweise in Form von Führungsblechen 45, 46, können die Mitnehmer 43, 44 im Bereich A in die auseinanderstehenden Hälften 5a, 5b der Falzprodukte 5 eingeführt werden. Der Transport der Bügel 5 mit den Mitnehmern 43, 44 kann wiederum durch einen mittig angeordneten Endlosriemen 44 oder eine entsprechende Kette vorgenommen werden.Finally, Fig. 12 shows a further variant. Here, two pivotable arms 43, 44 are fastened to a bracket 42, the width of which, as indicated by double arrows, can be adapted to the widths of the folded products 5, for example by means of a telescopic design. By means of laterally arranged control means, for example in the form of guide plates 45, 46, the drivers 43, 44 in region A can be introduced into the halves 5a, 5b of the folded products 5 which are spaced apart. The transport of the bracket 5 with the drivers 43, 44 can in turn be carried out by a centrally arranged endless belt 44 or a corresponding chain.

Die Weiterverarbeitung, beispielsweise das Einfügen von Beilagen oder das Sammeln von Falzprodukten 5, kann in vorteilhafter Weise mit Vorrichtungen erfolgen, die in der zeitlich gleichrangigen Anmeldung PB 8286/1689 beschrieben sind.The further processing, for example the insertion of inserts or the collection of folded products 5, can advantageously be carried out using devices which are described in the application PB 8286/1689, which has the same priority.

Es versteht sich, dass die Erfindung auch bei einer Falzvorrichtung verwendet werden kann, in der das Falzprodukt (Bogen oder Bogenpakete) zwischen zwei Walzen mittels eines Messers hindurchgestossen wird. Auch hier entsteht ein keilförmiger Bereich (Zwickel), in den die Mitnehmer seitlich eingeführt werden können. Lediglich in Umfangsrichtung verlaufende Vertiefungen sind in den Walzen zur Durchführung der Mitnehmer gegebenenfalls vorzusehen.It goes without saying that the invention can also be used in a folding device in which the folded product (sheets or sheet packages) is pushed between two rollers by means of a knife. Here, too, a wedge-shaped area (gusset) is created, into which the drivers can be inserted laterally. Only in the circumferential direction recesses are to be provided in the rollers for the implementation of the driver if necessary.
