Description

trägt. Vorteile dieses 3:2-Räderfalzes sind Falzkapazitäten bis zu 160 Seiten und hohe Laufgeschwindigkeiten, weil die Sammelbogen nicht um einen 1/2-großen, sondern um einen 3/2- großen Zylinder geführt werden, der nur mit 2/3 der Drehzahl der 2/2-Plattenzylinder der Zeitungsrotationsmaschine rotiert und nur 1/3 der Fliehkräfte des 2:1-Falzapparates ausübt.wearing. Advantages of this 3: 2-wheel rebate are folding capacities of up to 160 pages and high running speeds, because the collecting sheets are not guided around a 1/2 large cylinder, but around a 3/2 large cylinder, which only rotates at 2/3 the speed of the 2/2 plate cylinder of the newspaper press rotates and exerts only 1/3 of the centrifugal force of the 2: 1 folder.

Nachteilig ist in erster Linie beim 3:2-Räderfalzapparat die komplizierte Bauform mit dem exzentrisch um den Falzmesserträger rotierenden hohlen Sammelzylinder. Das Umschalten von Doppel- auf Sammelproduktion durch Stillegung eines der beiden Falzmesser innerhalb des Hohlzylinders ist schlecht zugänglich und aufwendig. Schwerwiegender noch ist die Tatsache, daß der 2/2-Schneidmesserzylinder gegen den aus Konstruktionsgründen wenig stabilen, hohlen Sammelzylinder schneidet. Beim Schnitt starkseitiger Zeitungen treten erhebliche Schnittkräfte auf. Die Wechselbiegung durch Fliehkraft und Schneidkraft hat in der Praxis zu Materialermüdungen am hohlen Sammelzylinder und gefährlichen Dauerbrüchen geführt.The main disadvantage of the 3: 2-wheel folder is the complicated design with the hollow collecting cylinder rotating eccentrically around the folder holder. Switching from double to collective production by decommissioning one of the two folding knives within the hollow cylinder is difficult to access and complex. Even more serious is the fact that the 2/2 cutting knife cylinder cuts against the hollow collecting cylinder, which is not very stable for design reasons. When cutting thick-sided newspapers, considerable cutting forces occur. The alternating bending caused by centrifugal force and cutting force has in practice led to material fatigue on the hollow collecting cylinder and dangerous fatigue fractures.

Ein anderer 3:2-Räderfalz nach US-PS 31 44 249 arbeitet innerhalb des 3/2-Sammelzylinders mit drei rotierenden Falzmessern. Das Umschalten von Doppel- auf Sammelproduktion erfolgt hier bequem von außen durch absatzweises Mitlaufenlassen des Sonnenrades, wodurch jede zweite Hypozykloidenspitze unterdrückt wird. Bei stillstehendem Sonnenrad schlagen jedoch alle drei Messer gleichzeitig zu Hypozykloidenspitzen aus. Deshalb muß auch bei diesem Räderfalz ein 3/2-großer, hohler Sammelzylinder als relativ schwache Hülle und exzentrisch versetzt zur Achse des Falzmesserträgers umlaufen, um die oberen Hypozykloidenspitzen nicht aus der Hülle des Sammelzylinders heraustreten zu lassen. Auch diese Konstruktion ist deshalb durch auftretende hohe Schnittkräfte auf den hohlen Sammelzylinder gekennzeichnet und gefährdet durch Ermüdungsbrüche.Another 3: 2-wheel fold according to US-PS 31 44 249 works within the 3/2-cylinder with three rotating folding knives. Switching from double to collective production is done conveniently from the outside by letting the sun gear move along in batches, which suppresses every second hypocycloid tip. When the sun gear is at a standstill, however, all three knives swing to hypocycloid tips simultaneously. Therefore, a 3/2-sized, hollow collecting cylinder must rotate as a relatively weak casing and eccentrically offset to the axis of the folding knife carrier, so that the upper hypocycloid tips do not come out of the casing of the collecting cylinder let it come out. This construction is therefore also characterized by high cutting forces on the hollow collecting cylinder and endangered by fatigue fractures.

Im Gegensatz zu den beschriebenen 3:2-Räderfalzapparaten arbeitet US-PS 33 48 837 ohne exzentrisch versetzt umlaufenden 3/2-Sammelzylinder. Hier ist der 3/2-Zylinder als Massivzylinder ausgeführt und drei rotierende Falzmesser sind ortsfest im Sammelzylinder, der gleichzeitig Falzmesserträger ist, gelagert. Die hohen Schnittkräfte zwischen 2/2-Schneidzylinder und 3/2-Sammelzylinder werden so von Massivzylindern aufgenommen.In contrast to the 3: 2-wheel folding apparatus described, US Pat. No. 3,348,837 works without an eccentrically offset rotating 3/2 collecting cylinder. Here the 3/2-cylinder is designed as a solid cylinder and three rotating folding knives are fixed in the collecting cylinder, which is also the folding knife holder. The high cutting forces between the 2/2 cutting cylinder and the 3/2 collecting cylinder are thus absorbed by solid cylinders.

Ein hohler Sammelzylinder, der hohe Schnittkräfte aufnehmen muß, fehlt, damit gibt es keine Gefahr von Haarrissen und Ermüdungsbrüchen. Nachteilig ist jedoch wie bei allen 3:2- Räderfalzapparaten, der stark schwankende Papierzug auf die einlaufenden Stränge bei Sammelproduktion, was zu ausgeschlitzten Punkturlöchern und abfliegenden Exemplaren führen kann. Denn die Bahnen werden abwechselnd vom Radius der nächsten 3/2-Zylinderoberfläche und dann vom durch die umlaufende - dicke - Sammellage vergrößerten Radius gezogen. Ferner ist bei US-PS 33 48 837 nachteilig, der erhebliche Getriebeaufwand um bei Sammelbetrieb - d. h. auf zwei Zylinderumdrehungen für jedes der drei Falzmesser vier von sechs an sich auftretenden Hypozykloidenspitzen durch entsprechendes Mitlaufen der jeweiligen Sonnenräder zu eliminieren.A hollow collecting cylinder, which has to absorb high cutting forces, is missing, so there is no risk of hairline cracks and fatigue breaks. However, a disadvantage, as with all 3: äderfalzapparaten 2 R, the widely fluctuating paper pull on the incoming strands in collect production, which can lead to ausgeschlitzten Punkturlöchern and departing copies. Because the orbits are drawn alternately by the radius of the next 3/2-cylinder surface and then by the radius enlarged by the circumferential - thick - collecting layer. It is also disadvantageous in US Pat. No. 3,348,837 that the considerable gear expenditure in order to eliminate four out of six hypocycloid tips occurring for each of the three folding knives by corresponding running of the respective sun gears during collective operation - ie on two cylinder revolutions.

Aufgabe der Erfindung ist ein Räderfalzapparat für Doppel- und Sammelproduktion starker Produkte bei hohen Laufgeschwindigkeiten, d. h. mit einem Zylinderverhältnis vom Falzmesserzylinder zu Schneidzylinder größer als 2:1 zu schaffen. Dabei - sollen die hohen Schnittkräfte von massiven Zylindern aufgenommen werden können. Bei Doppel- und Sammelproduktion soll ein fast gleichmäßiger Papierzug angestrebt werden.The object of the invention is a wheel folder for double and collective production of strong products at high speeds speed, ie with a cylinder ratio of the folding knife cylinder to the cutting cylinder greater than 2: 1. The high cutting forces of massive cylinders should be able to be absorbed. In the case of double and bulk production, an almost uniform paper draw should be aimed for.

Der Räderfalzapparat entsprechend der Erfindung besteht aus einem Schneidmesserzylinder, der am Umfang drei Satz Schneidmesser trägt und drei Punktursätze, so daß er auch als 3/2-Sammelzylinder dienen kann.The wheel folder according to the invention consists of a cutting knife cylinder which carries three sets of cutting knives on the circumference and three point sets, so that it can also serve as a 3/2 collecting cylinder.

Der Gegenschneidzylinder hat auch 3/2-Umfang, trägt drei Gegenschneidleisten, drei Satz Punkturen und drei rotierende Falzmesser, die immer normale Hypozykloiden mit drei Spitzen beschreiben. Die Spitze des unteren Falzmesseranschlages stößt die Produkte in entsprechend angeordnete Falzwalzen. In vorteilhafter Weise arbeitet jedes Schneidmesser nicht überspringend, sondern stets mit der gleichen Gegenschneidleiste zusammen. Weiter sind Mittel vorhanden, um die Punkturen des 3/2-Schneidmesser-Sammelzylinders und des 3/2-Falzmesserzylinders wahlweise derart zu steuern, daß Doppel- oder Sammelproduktion entsteht.The counter-cutting cylinder also has a 3/2 circumference, carries three counter-cutting bars, three sets of punctures and three rotating folding knives, which always describe normal hypocycloids with three tips. The tip of the lower folding knife stop pushes the products into correspondingly arranged folding rollers. In an advantageous manner, each cutting knife does not work in a skipping manner, but always works with the same counter-cutting bar. Means are also available to selectively control the punctures of the 3/2 cutting knife collecting cylinder and the 3/2 folding knife cylinder in such a way that double or collective production occurs.

Vorteilhaft ist bei dem erfindungsgemäßen Räderfalzapparat, daß exzentrisch versetzt umlaufende Hohlzylinder entfallen können. Die einlaufenden Stränge können bei Doppel- und Sammelproduktion mit fast gleichmäßigem, d. h. nicht stark pulsierendem Papierzug von der Falzzylindergruppe gezogen werden. Weiter ist von Vorteil, daß Überlagerungs- und sonstigen Getrieben entfallen, d. h. die rotierenden Falzmesser können von robusten, einfachen Getrieben erzeugte Hypozykloiden beschreiben. Schließlich hat die Falzzylindergruppe nicht mehr als zwei Zylinder.It is advantageous in the wheel folding apparatus according to the invention that hollow cylinders rotating in an eccentrically offset manner can be dispensed with. The incoming strands can be used in double and bulk production with almost even, i.e. H. not very pulsating paper pull are pulled from the folding cylinder group. Another advantage is that superimposition and other gears are eliminated, i. H. the rotating folding knives can describe hypocycloids produced by robust, simple gears. After all, the folding cylinder group has no more than two cylinders.

Der erfindungsgemäße 3:3-Falzapparat d.h. dreifeldriger Falzmesserzylinder und dreifeldriger Schneidzylinder zeichnet sich durch platzsparende, einfache und robuste Bauart aus. Bei Sammelproduktion läuft die Sammellage im Gegensatz zu bekannten 3:2-Falzapparaten um den Schneidzylinder herum und wird ähnlich wie bei 2:1-Falzapparaten von oben auf den einlaufenden Strang aufgenadelt. Hierbei vergrößert die Sammellage nicht den Radius des 3/2-Falzmesserzylinders, so daß der Papierzug von der Sammellage nicht beeinflußt wird. Bei Doppel- und Sammelproduktion bestehen nahzu gleiche Zugverhältnisse, weil 3/2-Falzmesser- und 3/2-Schneidzylinder gleichgroße Krümmungen aufweisen; es bleibt für den einlaufenden Strang gleich, oo z. B. Doppelproduktion pro Abschnitt vom 3/2-Falzmesserzylinder oder bei Sammelproduktion abwechselnd vom 3/2-Schneidn,gsser-Sammelzylinder und vom 3/2-Falzmesserzylinder aufgenadelt und transportiert wird.The 3: 3 folder according to the invention, ie three-field folding knife cylinder and three-field cutting cylinder, is characterized by space-saving, simple and robust construction. In the case of collective production, in contrast to known 3: 2 folders, the collecting layer runs around the cutting cylinder and, similarly to 2: 1 folders, is needled onto the incoming strand from above. Here, the gathering layer does not increase the radius of the 3/2-fold knife cylinder, so that the paper pull is not influenced by the gathering layer. In double and bulk production there are almost the same draw ratios because 3/2 folding knife and 3/2 cutting cylinders have curvatures of the same size; it remains the same for the incoming strand, oo z. B. Double production per section from the 3/2-folding-blade cylinder or collect production alternately needled from 2-folding-blade cylinder 3/2-Schneidn, g ter-collecting cylinder and the 3 / and transported.

Der Schneid-/Sammelzylinder ist in so tiefer Lage am Falzmesserzylinder angeordnet, daß die oben rechts austretende Hypozykloidenspitze den einlaufenden Strang nicht berührt. Da andererseits im Gegensatz zu bisherigen 3:2-Räderfalzapparaten nicht mehr auf dem 3/2-Gegenschneid-Falzmesserzylinder gesammelt wird, dürften die Falzmesser mehrfach - dreimal - aus der Falzmesserzylinderoberfläche austreten, so daß eine einfache, unmodifizierte Falzmesserbewegung verwendet werden kann. Es brauchen auch keine Falzmesser bei Sammelproduktion still gelegt werden; bei Sammelproduktion stößt einfach jeder zweite Falzmesserhub ins Leere, weil die zugehörige Sammellage nicht auf dem Falzmesserzylinder, sondern auf dem anderen 3/2-Schneid-Sammelzyinder transportiert wird.The cutting / collecting cylinder is arranged in such a low position on the folding knife cylinder that the hypocycloid tip emerging at the top right does not touch the incoming strand. On the other hand, since, in contrast to previous 3: 2-wheel folder devices, no more is collected on the 3/2 counter-cutting folder cylinder, the folder knives should emerge several times - three times - from the folder cylinder surface, so that a simple, unmodified folder movement can be used. There is also no need to shut down folding knives during bulk production; in the case of collective production, every second folding knife stroke simply does not work because the associated collecting layer is not transported on the folding knife cylinder, but on the other 3/2-cutting collecting cylinder.

Während die Neuheiten des Räderfalzapparates nach der Erfindung in den Patentansprüchen festgelegt sind, kann ein volles Verständnis der Erfindung durch die Beschreibung der Wirkungsweise und die Abbildungen gewonnen werden.While the innovations of the wheel folder according to the invention are defined in the patent claims, a full understanding of the invention can be gained from the description of the mode of operation and the illustrations.

Bei Doppelproduktion sind die Punkturen 17.1 bis 17.3 in der Schnittlinie immer eingezogen und die Punkturen 9.1 bis 9.3 immer ausgefahren, so daß alle Bogen nach dem Schnitt um den Falzmesserzylinder 8 geführt und sofort in die Falzwalzen 11 gestoßen werden.A 3/2 cutting knife cylinder 15 carries three cutting knives 16 offset by 120 °, as well as three sets of controllable punctures 17.1; 17.2; 17.3. In the case of double production, the punctures 17.1 to 17.3 are always drawn in in the cutting line and the punctures 9.1 to 9.3 are always extended, so that after the cut all sheets are guided around the folding blade cylinder 8 and immediately pushed into the folding rollers 11.

Bei Sammelproduktion werden die Punkturen 9.1 bis 9.3, 17.1 bis 17.3 abwechselnd derart gesteuert, daß ungeradzahlige (A)-Bogen um den Schneid-Sammelzylinder 15 herum geführt und jeweils drei Schritte später gemeinsam mit einem geradzahligen (B)-Bogen durch Punkturen 9.1 bis 9.3 des Falzmesserzylinders 8 aufgenadelt und zu den Falzwalzen 11 geführt werden, in die die rotierenden Falzmesser 12 bis 14 hineinragen.In collective production, the punctures 9.1 to 9.3, 17.1 to 17.3 are alternately controlled in such a way that odd-numbered (A) arcs are guided around the cutting-collecting cylinder 15 and three steps later together with an even-numbered (B) arch through punctures 9.1 to 9.3 of the folding blade cylinder 8 are needled and guided to the folding rollers 11, into which the rotating folding blades 12 to 14 protrude.

Der Antrieb des Zweizylinder-Falzapparates erfolgt über eine Längswelle 20, Stehwelle 21, Querwelle 22. Von der Stehwelle 21 wird auch der Antrieb für die Zugwalzen 6, 7 und die Trichtereinlaufwalze 23 abgeleitet.The two-cylinder folder is driven by a longitudinal shaft 20, standing shaft 21, transverse shaft 22. The drive for the pulling rollers 6, 7 and the hopper inlet roller 23 is also derived from the standing shaft 21.

Fig. 2.1 bis 2.6 erklären die Sammelproduktion beim Anlaufen. Erster Bogen 101 hängt in Punkturen 17.1 des Schneid-Sammelzylinders 15, Punktur 9.2 nimmt Bogen 102, während Punktur 17.2 im Schneid-Sammelzylinder 15 sich zurückzieht.Fig. 2.1 to 2.6 explain the collective production when starting up. First sheet 101 hangs in punctures 17.1 of cutting collecting cylinder 15, puncture 9.2 takes sheet 102, while puncture 17.2 in cutting collecting cylinder 15 withdraws.

Zweiter Bogen 102 (Fig. 2.2) wird von Punktur 9.2 um Falzmesserzylinder 8 herum zum Falzen geführt, während Punktur 9.3 zurückgezogen ist. Dafür nimmt Punktur 17.3 Bogen 103 und führt ihn - Fig. 2.3 - um den Schneid-Sammelzylinder 15. Punktur 17.1 hat Bogen 101 erneut zur Schnittlinie gebracht - hier wird er von Punktur 9.1, die schon einlaufenden Bogen 104 erfaßt hat, übernommen.Second sheet 102 (FIG. 2.2) is guided from point 9.2 to folding knife cylinder 8 for folding, while point 9.3 is withdrawn. For this purpose, point 17.3 takes sheet 103 and guides it - Fig. 2.3 - around the cutting collecting cylinder 15. Point 17.1 has brought sheet 101 again to the cutting line - here it is taken from point 9.1, which has already entered incoming sheet 104.

In Fig. 2.4 ist erstmals ein Sammelzyklus vollendet. Auf FalzmesserzylinderoDerfläche 8 liegender Bogen 104 mit außen liegendem Sammelbogen 101 werden in die Falzwalzen 11 gestoßen. Punkturen 17.2 holen sich Sammelbogen 105. Er läuft - Fig. 2.5 - um Sammelzylinder 15, während Sammelbogen 103 von Punktur 17.3 auf Punktur 9.3 mit bereits aufgenadelten Bogen 106 übergeben wird.2.4, a collection cycle is completed for the first time. Sheets 104 lying on the folding knife cylinder surface 8 with the collecting sheet 101 on the outside are pushed into the folding rollers 11. Punctures 17.2 get collecting sheet 105. It runs - FIG. 2.5 - around collecting cylinder 15, while collecting sheet 103 is transferred from point 17.3 to point 9.3 with sheet 106 already needled.

In Fig. 2.6 wird Sammelprodukt 106 + 103 (vorher 104 + 101) vom Falzmesser in die Falzwalzen 11 gestoßen.2.6, collecting product 106 + 103 (previously 104 + 101) is pushed into the folding rollers 11 by the folding knife.

Es werden also immer Pakete von geradzahligen (B) und ungeradzahligen (A)- Bogen gebildet, wobei wegen des Schneid-Sammelzylinders mit drei Feldern immer ein Sprung über drei Sammelexemplare gemacht wird.So packages of even-numbered (B) and odd-numbered (A) arcs are always formed, whereby because of the cutting-collecting cylinder with three fields, a jump is always made over three collective copies.

Fig. 3.1 und 3.2 zeigen eine mögliche Punkturensteuerung für den 3/2-Falzmesserzylinder 8 und 3/2-Schneid-Sammelzylinder 15. Alle Punkturen 9.1 bis 9.3, 17.1 bis 17.3 laufen um ortsfeste Kurven 32; 33 und sind bei großem Radius der Kurven 32; 33 ausgefahren. Zum Eintauchen der Punkturen 9.1 bis 9.3, 17.1 bis 17.3 sind Aussparungen 34; 35; 36 (Kurventäler) mit kleinerem Grundradius vorhanden, in die die Punkturen-Antriebsrollen unter Federbelastung hineintauchen und dadurch die Punkturen 9.1 bis 9.3 und 17.1 bis 17.3 zurückziehen. Dieses Eintauchen kann durch rotierende Deckscheiben 37; 38 verhindert werden, die zeitweise die Kurventäler 34; 35; 36 abdecken.3.1 and 3.2 show a possible puncture control for the 3/2 folding knife cylinder 8 and 3/2 cutting collecting cylinder 15. All punctures 9.1 to 9.3, 17.1 to 17.3 run around stationary curves 32; 33 and are at a large radius of the curves 32; 33 extended. For the immersion of the punctures 9.1 to 9.3, 17.1 to 17.3 there are cutouts 34; 35; 36 (curve valleys) with a smaller base radius, into which the puncture drive rollers dip under spring load and thereby withdraw the punctures 9.1 to 9.3 and 17.1 to 17.3. This immersion can be done by rotating cover disks 37; 38 can be prevented, which temporarily the curve valleys 34; 35; 36 cover.

Die Deckscheiben 37; 38 rotieren gegenläufig zum Drehsinn der zugehörigen Zylinder 8, 15, jedoch nur mit 3/4 der Zylinderdrehzahl.The cover plates 37; 38 rotate counter to the direction of rotation of the associated cylinders 8, 15, but only at 3/4 of the cylinder speed.

In Fig. 3.1 schließt Deckscheibe 37 Kurvental 34 und läßt Punkturen 9.2 des Falzmesserzylinders ausgefahren. Am Schneid-Sammelzylinder 15 bleibt Kurvental 36 der ortsfesten Steuerkurve 33 offen, weil Deckscheibe 38 in 90° Entfernung vom Kurvental 36 steht. Folglich zieht sich Sammelpunktur 17.2 zwecks Bogenübergabe an Punktur 9.2 zurück. Punktur 9.2 führt den nachfolgenden Bogen 102 um den Falzmesserzylinder 8. Die Stellung entspricht den Phasen 2.1 und 2.3 und 2.5.In Fig. 3.1 cover plate 37 closes curve 34 and allows punctures 9.2 of the folding knife cylinder to extend. At the cutting-collecting cylinder 15, the cam 36 of the fixed control cam 33 remains open because the cover disk 38 is at a 90 ° distance from the cam 36. As a result, collection point 17.2 withdraws to point 9.2 for the purpose of transferring the bow. Puncture 9.2 guides the following sheet 102 around the folding knife cylinder 8. The position corresponds to phases 2.1 and 2.3 and 2.5.

Nach 120° Zylinderdrehung ergibt sich Fig. 3.2 (bzw. Phasenbilder Fig. 2.2 und 2.4 und 2.6). Wegen 3/4-Übersetzung sind beide Deckscheiben 37; 38 um 120° x 3/4 = 90° weitergelaufen. Deckscheibe 38 schließt Kurvental 36 von Kurve 33, läßt Punkturen 17.3 ausgefahren,um den nachfolgenden Bogen 103 um den Schneid-Sammelzylinder 15 zu führen. Auf dem Falzmesserzylinder 8 zieht sich Punktur 9.2 zurück, weil Kurvental 35 um 120° versetzt hinter Kurvental 34 liegt und die umlaufende Deckscheibe 37 nur um 90° weitergelaufen ist. Zum Zeitpunkt Fig. 3.2 (bzw. Phasenbildreihe Fig. 2.2 und Fig. 2.4 und Fig. 2.6) steht die Deckscheibe 37 um 30° vor Kurvental 35, läßt das Kurvental 35 aktiv und die Punktur 9.2 zurückziehen. Der Deckscheibenmechanismus arbeitet derart, daß bei jeder zweiten vorbeilaufenden Punktur 9.1 bis 9.3, 17.1 bis 17.3 abwechselnd Kurventäler 34 für Falzmesserzylinder 8 und Kurvental 36 für Schneid-Sammelzylinder 15 überdeckt werden, während das um 120° versetzte Kurvental 35 für jede vorbeilaufende Punktur 9.1, 9.2 und 9.3 aktiv bleibt, d.h. nicht überdeckt wird.After a 120 ° cylinder rotation, Fig. 3.2 (or phase images Fig. 2.2 and 2.4 and 2.6) results. Because of 3/4 ratio both cover plates 37; 38 continued through 120 ° x 3/4 = 90 °. Cover disk 38 closes curve 36 of curve 33, allows punctures 17.3 to be extended in order to guide the subsequent sheet 103 around the cutting collecting cylinder 15. Puncture 9.2 retracts on the folding knife cylinder 8, because cam 35 is offset by 120 ° behind cam 34 and the circumferential cover plate 37 has only continued to run by 90 °. At the time of Fig. 3.2 (or phase series of Fig. 2.2 and Fig. 2.4 and Fig. 2.6), the cover plate 37 is 30 ° in front of curve 35, leaves the curve 35 active and the puncture 9.2 withdrawn. The cover disk mechanism works in such a way that with every second passing puncture 9.1 to 9.3, 17.1 to 17.3, alternating cam valleys 34 for folding knife cylinder 8 and cam 36 for cutting collecting cylinder 15 are covered, while the cam 35 offset by 120 ° for each passing puncture 9.1, 9.2 and 9.3 remains active, ie is not covered.

Beide umlaufenden Deckscheiben 37; 38 haben zum Überdeckken der Kurventäler 34; 35; 36 zwei um 180° versetzte Kreisbogenstücke. Sie sind über Zahnräder 40; 41 und, Zwischenräder 42; 43 angetrieben im Umlaufverhältnis 3:4 durch Antriebsräder 44; 45.Both circumferential cover disks 37; 38 have 34; 35; 36 two circular arc pieces offset by 180 °. They are over gears 40; 41 and, intermediate wheels 42; 43 driven in rotation ratio 3: 4 by drive wheels 44; 45.

Das, Umschalten von Sammelproduktion auf Doppelproduktion erfolgt in einfachster Weise durch Auskuppeln des Abtriebsrades 45 von Antriebsrad 44. Hierzu wird Abtriebsrad 45 seitlich verschoben und gegen ein gestellfestes Zahnstück verriegelt. Dabei stehen beide Deckscheiben 37; 38 in Position der Fig. 3.1 unbeweglich fest verriegelt.Switching from collective production to double production takes place in the simplest way by disengaging the driven wheel 45 from the driven wheel 44. For this purpose, the driven wheel 45 is shifted laterally and locked against a tooth piece fixed to the frame. Both cover disks 37; 38 in the position of Fig. 3.1 locked immovably.

Folglich bleiben alle Falzmesserzylinder-Punkturen 9 im Schnittbereich der Zylinder 8, 15 ausgefahren und führen jeden Bogen um den Falzmesserzylinder 8 zu den Falzwalzen 11, wo alle Punkturen 9.1 bis 9.3 gesteuert durch Kurvental 35 die Bogen zum Falzen freigeben.Consequently, all folding knife cylinder punctures 9 remain extended in the cutting area of the cylinders 8, 15 and lead each sheet around the folding knife cylinder 8 to the folding rollers 11, where all punctures 9.1 to 9.3 controlled by the curve 35 release the sheets for folding.

Am Schneid-Sammelzylinder 1'5 bleibt Kurvental 36 immer aktiv, so daß Punkturen 17.1 bis 17.3, immer eingezogen durch die Schnittstelle laufen und keinen Sammel-Bogen um den Schneid-Sammelzylinder 15 führen können.At the cutting-collecting cylinder 1'5, cam 36 always remains active, so that punctures 17.1 to 17.3, always drawn through the interface, cannot pass a collecting arc around the cutting-collecting cylinder 15.

Hier ist nur eine bevorzugte Ausführungsform des erfindungsgemäßen Räderfalzapparates beschrieben. Andere Ausführungsformen sind möglich. So kann das Zylinderverhältnis statt 3:3 auch 5:5 oder 7:7 gewählt werden, um die Fliehkraftwerte zu verringern. Während der Schneid-Sammelzylinder 15 immer eine ungerade Anzahl von Punkturen bzw. Feldern aufweisen muß, kann der Falzmesserzylinder 8 auch eine gerade Anzahl haben. Somit sind auch 4:3 oder 6:3 oder 6:5 Verhältnisse möglich. Es könnten auch Schneidmesser und Gegenschneidleisten auf den Zylindern 8, 15 vertauscht angeordnet sein, was aber durch die vorstehenden Schneidmesser beim Falzvorgang zu Störungen führt und nicht zu empfehlen ist.Only a preferred embodiment of the wheel folder according to the invention is described here. Other embodiments are possible. The cylinder ratio can also be selected from 5: 5 or 7: 7 instead of 3: 3 to reduce the centrifugal force values. While the cutting-collecting cylinder 15 must always have an odd number of punctures or fields, the folding knife can cylinders 8 also have an even number. This means that 4: 3 or 6: 3 or 6: 5 ratios are also possible. Cutting knives and counter-cutting bars could also be interchanged on the cylinders 8, 15, but this leads to malfunctions during the folding process due to the above cutting knives and is not recommended.

In weiterer Ausbildung der Erfindung wird beim zweiten Durchlauf des Sammelbogens durch die Schnittstelle ein Schnipseln dadurch vermieden, daß der Durchmesser des Schneid-Sammelzylinders 15 geringfügig kleiner als der Durchmesser des Falzmesserzylinders 8 gehalten ist. Dadurch werden die um den Schneid-Sammelzylinder umlaufenden Lagen etwas kürzer geschnitten als um Falzmesserzylinder 8 herumgeführte Lagen. Ein weiterer Verkürzungseffekt für die Sammellagen tritt dadurch auf, daß sie auf dem etwas größerem Falzmesserzylinder nicht auf der Zylinderoberfläche, sondern auf einem um die Dicke des Bogenpaketes vergrößerten Radius umlaufen, so daß der eingenommene Winkel kleiner als 120° ist.In a further embodiment of the invention the second pass of the collection sheet is chnipseln through the interface, an S avoided in that the diameter of the cutting-collecting cylinder is kept slightly smaller than the diameter 15 of the folding blade cylinder. 8 As a result, the layers revolving around the cutting-collecting cylinder are cut somewhat shorter than the layers guided around the folding knife cylinder 8. Another shortening effect for the collecting layers occurs in that they run on the somewhat larger folding knife cylinder not on the cylinder surface, but on a radius increased by the thickness of the sheet package, so that the angle taken is less than 120 °.
