Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Zusammenführen von zwei in Falztrichtern gefaltzen Bedruckstoffbahnen in einer Rollenrotationsdruckmaschine nach dem Oberbegriff von Anspruch 1. Die Erfindung betrifft ebenso ein Verfahren zum Zusammenführen von Bedruckstoffbahnen entsprechend dem Oberbegriff von Anspruch 11. The present invention relates to a device for merging two in Folding hoppers fold printing material webs in a web-fed rotary printing press after the Preamble of claim 1. The invention also relates to a method for Merging printing material webs according to the preamble of claim 11.

Im Rollenrotationsdruck sind Bedruckstoffteilbahnen nach dem Längsfalzen, das üblicherweise durch Förderung der Bahnen durch Trichter hindurch erfolgt, wieder zusammenzuführen, bevor sie einem Falzapparat zugeführt werden. Die Bahnanfange der einzelnen Teilbahnen, werden dabei über entsprechende Überführungsvorrichtungen zu einem einzigen Bahnstrang, in dem die längsgefalzten Bedruckstoffbahnen in etwa deckend übereinanderliegen, zusammengeführt. Das Zusammenführen der Teilbahnen bzw. das Einziehen der Teilbahnen über die hierfür im Bereich des Überführens vorgesehenen Umlenkmittel, insbesondere Umlenkwalzen, erfolgt üblicherweise per Hand. Eine Bedienperson übernimmt hierbei einen Bahnanfang solch einer längsgefalzten Teilbahn, beispielsweise mittels eines Hakens, und übergibt den aufgenommenen Bahnanfang an eine zweite Bedienperson, die den übernommenen Bahnanfang im Bereich eines Aufgabemittels, insbesondere einer Bahn-Umleitwalze, so aufgibt bzw. einfädelt, daß dieser Bahnanfang mit einer im Bereich des Aufgabemittels endlos geförderten anderen Teilbahn in Deckung zu liegen kommt und zusammen mit dieser anderen Teilbahn weiter gefördert wird. Das manuelle Zusammenführen von Teilbahnen ist zeitaufwendig, störanfallig und erfordert die Zusammenarbeit von zumindest zwei Bedienpersonen. In web-fed rotary printing, substrate webs are after the longitudinal folding, which usually done by conveying the webs through funnels again before they are fed to a folder. The start of the train of the individual sub-lanes are transferred using appropriate transfer devices to a single web strand in which the longitudinally folded printing material webs approximately overlapping, merged. Merging of the partial webs or the drawing in of the partial webs via the for this purpose in the area of Conveying provided deflection means, in particular deflection rollers usually by hand. An operator takes over a start of the path such a longitudinally folded partial web, for example by means of a hook, and transfers the recorded start of the web to a second operator who assumed path start in the area of a feed means, in particular one Web diverter roller, so gives up or threading that this web start with an in Area of the feed means endlessly subsidized other partial web to cover lies and is further promoted together with this other sub-lane. The manual merging of partial webs is time consuming, prone to failure and requires the cooperation of at least two operators.

Aus DE 26 14 665 A ist ein Gegenstand mit einer Vorrichtung und einem Verfahren offenbart der den Oberbegriffen der Ansprüche 1 und 11 entspricht.DE 26 14 665 A describes an object with an apparatus and a method discloses which corresponds to the preambles of claims 1 and 11.

Die Erfindung hat es sich zur Aufgabe gemacht, das Zusammenführen von in Falztrichtern gefalzten Bedruckstoffbahnen in einer Rollenrotationsdruckmaschine zu ermöglichen, ohne dass dazu eine Bedienperson notwendig ist. The invention has set itself the task of merging in formers to allow folded printing material webs in a web-fed rotary printing press without that an operator is necessary for this.

Diese Aufgabe wird durch die Gegenstände der Ansprüche 1 und 11 gelöst. This object is solved by the subject matter of claims 1 and 11.

Das Überführband wird bevorzugterweise durch Anstellen gegen ein Bahnfördermittel, vorzugsweise das Umlenkmittel, von diesem mitangetrieben. In einer ebenfalls bevorzugten Ausführungsform wird es durch einen eigenen Motor angetrieben.The transfer belt is preferably held against a web conveyor, preferably the deflection means, driven by this. In a also preferred embodiment is by its own engine driven.

Bei dem Umlenkmittel kann es sich um eine Umlenkwalze, insbesondere eine Registerwalze, und bei dem Aufgabemittel kann es sich um eine dazu beabstandet angeordnete Bahn-Umleitwalze handeln. Kurz hinter dieser Bahn-Umleitwalze, nämlich dem Aufgabemittel, läuft die überführte Bedruckstoffbahn unter eine weitere zuvor längsgefalzte Bedruckstoffbahn, nämlich die Bahn, mit der sie zum anschließenden Kappen und Falzen zusammengeführt werden soll. Eine Rollenrotationsdruckmaschine kann mehrere Überführungsvorrichtungen, die meist quer zur Bahnförderrichtung nebeneinander angeordnet sind, aufweisen.The deflecting means can be a deflecting roller, in particular a register roller, and the feeding means can be one for this act spaced web diverter roller. Shortly behind this web diversion roller, namely the feed means, the transferred substrate runs under another previously longitudinally folded printing material web, namely the web with which it is to be merged for subsequent trimming and folding. A Web-fed rotary printing press can have several Transfer devices, usually side by side transversely to the web conveying direction are arranged.

Das Umlenkmittel und das Leitmittel bilden eine Art Einlauftrichter für den Bahnanfang der zu überführenden Materialbahn. Gerade in der Verwendung für Rollenrotationsdruckmaschinen, wird der betreffende Bahnanfang aus dem Falztrichter im wesentlichen vertikal nach unten zu einer Umlenkwalze gefördert und um etwa 90° aus seiner Förderrichtung in eine seitlich neben diese Umlenkwalze angeordneten weiteren Umlenkwalze gefördert. Wegen dieser durch die Schwerkraft unterstützten Bahnförderung genügt ein nach oben offener Einlauftrichter vollkommen zum sicheren Umleiten des freihängenden Bahnanfangs.The deflecting means and the guiding means form a kind of inlet funnel for the beginning of the web of the material web to be transferred. Especially in the Use for web-fed rotary printing presses, the web start in question from the former essentially vertically downwards to a deflecting roller conveyed and by about 90 ° from its conveying direction in a side next to this Deflection roller arranged further deflection roller promoted. Because of this gravity-assisted web conveying is sufficient with an inlet funnel open at the top perfect for safely diverting the free-hanging path start.

In einer besonders bevorzugten Ausführungsform der Erfindung bildet das Überführband gleichzeitig auch das Umleitmittel. Zum Umleiten eines Bahnanfangs umschlingt dieses Überführband das Umlenkmittel teilweise. Das Überführband ist vorteilhafterweise um zumindest drei Bandumleitwalzen, die zueinander dreieckförmig angeordnet sind, geführt. Zum teilweisen Umschlingen des Umlenkmittels ist das Überführband bevorzugterweise im Bereich eines Trums, insbesondere eines Obertrums, gegen das Umlenkmittel angedrückt bzw. angestellt.In a particularly preferred embodiment of the invention that forms Conveyor belt also the diversion. To redirect a path start this transfer belt partially wraps around the deflecting means. The transfer belt is advantageously around at least three belt diversion rollers, which are triangular to one another are arranged, guided. For partially looping around the deflecting means the transfer belt preferably in the area of a run, in particular one Upper run, pressed or turned against the deflecting means.

Bevorzugterweise ist das Überführband zum Anstellen an das Umlenkmittel schwenkbar angeordnet. Indem das Überführband mit einer teilweisen Umschlingung des Umlenkmittels an das Umlenkmittel anstellbar ist, kann es dementsprechend nach Überführung des Bahnanfangs und Weiterförderung der überführten Materialbahn wieder von dem Umlenkmittel abgestellt werden, so daß die überführte Materialbahn nur über die sonst üblichen Umlenkmittel geführt weiter gefördert werden kann. Durch das Abstellen nach erfolgter Überführung wird sehr einfach verhindert, daß möglicherweise auf das Überführband abgefärbte Druckfarbe auf die Materialbahn, falls es sich um eine Bedruckstoffbahn handelt, übertragen werden kann.The transfer belt is preferably to be used against the deflecting means pivotally arranged. By placing the transfer belt with a partial wrap of the deflecting means can be adjusted to the deflecting means, it can accordingly Transfer of the beginning of the web and further conveyance of the transferred material web be turned off again by the deflecting means, so that the transferred web of material can only be further promoted using the usual deflection means. By switching off after the transfer is very easily prevented possibly ink inked onto the transfer belt onto the material web, if it is a printing material web, can be transferred.

Eine der drei Bandumleitwalzen kann durch das Aufgabemittel selbst gebildet werden. Dies stellt auch eine bevorzugte Ausführungsform der Erfindung dar. Nach einer anderen bevorzugten Ausführungsform ist das Überführband von den sonstigen Umlenkmitteln der Rollenrotationsmaschine mechanisch unabhängig. Je nach Ausführungsform bildet entweder das als Umlenkwalze ausgebildete Aufgabemittel oder eine in unmittelbarer Nachbarschaft des Aufgabemittels angeordnete, gesonderte Bandumleitwalze den Antrieb des umlaufenden Überführbands.One of the three belt diverter rollers can be formed by the feed means itself become. This also represents a preferred embodiment of the invention Another preferred embodiment is the transfer belt from the others Deflection means of the roll rotating machine mechanically independent. Depending on Embodiment forms either the feed means designed as a deflection roller or a separate one arranged in the immediate vicinity of the feed means Belt deflection roller drives the rotating transfer belt.

Im letztgenannten Falle ist zwischen dieser Bandumleitwalze und dem Aufgabemittel ein zusätzliches Bahnauflagemittel zur Unterstützung des Bahnanfangs bei dessen Ein- bzw. Auflaufen in bzw. auf das Aufgabemittel angeordnet. Bei einer Rollenrotationsdruckmaschine, bei der das Aufgabemittel üblicherweise als Bahn-Umleitwalze ausgebildet ist, ist diese Umleitwalze hierzu vorteilhafterweise mit umlaufenden Nuten versehen, und das Bahnauflagemittel greift rechenförmig in diese Nuten ein, so daß eine nahtlose Aufgabe des Bahnanfangs gewährleistet werden kann.In the latter case there is between this belt diversion roller and the feed means an additional web support means to support the start of the web Arriving or running into or arranged on the feed means. With a web-fed rotary press, in which the feed means usually as a web diverter roller is designed, this diversion roller is advantageously with rotating Grooves, and the web support means engages in these grooves in a rake-like manner, so that a seamless task of the beginning of the path can be guaranteed.

In Figur 1 ist die Zusammenführung zweier Bedruckstoffteilbahnen B1 und B2, die jeweils in Trichtern T1 und T2 längsgefalzt worden sind, dargestellt. Die beiden längsgefalzten Bedruckstoffteilbahnen B1 und B2 werden jeweils über Zugwalzenpaare 15 gefördert, wobei der Bahnanfang jeder dieser beiden Teilbahnen B1 und B2 durch das jeweilige Zugwalzenpaar 15 zunächst freihängend in etwa vertikal nach unten gefördert wird. Unterhalb eines der beiden Zugwalzenpaare 15 ist ein Aufgabemittel, im Ausführungsbeispiel eine Bahn-Umleitwalze 17 angeordnet, an der der freie Bahnanfang der entsprechenden ersten Bedruckstoffteilbahn B1 in einem geringen Abstand vorbeigefördert bei seiner weiteren Förderung durch das Zugwalzenpaar 15 zu einem weiteren Zugwalzenpaar 18 gelangt, zwischen die beiden Walzen dieses Zugwalzenpaares 18 einläuft und von diesen weitergefördert wird.FIG. 1 shows the merging of two partial substrate webs B 1 and B 2 , each of which has been longitudinally folded in funnels T 1 and T 2 . The two longitudinally folded substrate sub-webs B 1 and B 2 are each conveyed via pulling roller pairs 15, the beginning of the web of each of these two sub-webs B 1 and B 2 being initially conveyed freely suspended approximately vertically downward by the respective pair of pulling rollers 15. Disposed below one of the two pairs of pull rollers 15 is a feed means, in the exemplary embodiment a web diverting roller 17, at which the free beginning of the web of the corresponding first printing substrate web B 1 is conveyed past at a short distance and is further conveyed by the pair of pull rollers 15 to another pair of pull rollers 18. runs between the two rollers of this pair of pull rollers 18 and is conveyed further by these.

Der Bahnanfang der anderen, zweiten Bedruckstoffteilbahn B2 muß zum Zusammenführen mit der ersten Bedruckstoffteilbahn B1 zunächst um eine in etwa vertikal unterhalb des zur Förderung der zweiten Bedruckstoffteilbahn B2 dienenden Zugwalzenpaares 15 angeordneten Umlenkmittel 16, im Ausführungsbeispiel ebenfalls eine Bahn-Umleitwalze, insbesondere eine Registerwalze, umgelenkt und zu dem Aufgabemittel 17 gefördert werden, um durch das Aufgabemittel 17 in die gleiche Richtung wie die im wesentlich einfach geradgeförderte erste Bedruckstoffteilbahn B1 umgelenkt zu werden.The beginning of the web of the other, second substrate sub-web B 2 must first be brought together with the first substrate sub-web B 1 by a deflection means 16 arranged approximately vertically below the pair of drawing rollers 15 used to convey the second substrate sub-web B 2 , in the exemplary embodiment also a web deflection roller, in particular one Register roller, are deflected and conveyed to the feed means 17 in order to be deflected by the feed means 17 in the same direction as the first printing substrate web B 1 , which is conveyed in a substantially simple manner.

Zum Überführen des Bahnanfangs der zweiten Teilbahn B2 wird dieser Bahnanfang mit Hilfe einer Überführvorrichtung 2 um das Umlenkmittel 16 gelenkt und auf dem Überführband 3 aufliegend zum Aufgabemittel 17 weitergefördert. Der Bahnanfang der zweiten Teilbahn B2 wird über das Aufgabemittel 17 in die Förderrichtung der ersten Teilbahn B1 umgelenkt und gelangt bei seiner Weiterförderung freihängend zwischen die Walzen des dem Aufgabemittels 17 nachgeordneten Zugwalzenpaars 18. Durch das Zugwalzenpaar 18 werden die beiden übereinanderliegenden Teilbahnen B1 und B2 über eine Rückhaltevorrichtung 19, eine Kappvorrichtung 20 und ein weiteres Zugwalzenpaar 21 in bekannter Weise zu einem Falzapparat 22 gefördert.In order to transfer the beginning of the web of the second partial web B 2 , this beginning of the web is steered around the deflection means 16 with the aid of a transfer device 2 and conveyed to the feeding means 17 lying on the transfer belt 3. The beginning of the web of the second sub-web B 2 is deflected in the conveying direction of the first sub-web B 1 via the feed means 17 and, during its further conveyance, it hangs freely between the rollers of the pair of pulling rollers 18 arranged downstream of the feed means 17. The pair of sub-webs B 1 and B 2 is conveyed to a folder 22 in a known manner via a retaining device 19, a cutting device 20 and a further pair of pull rollers 21.

Figur 2 zeigt die Bahnüberführungsvorrichtung 2 nach Figur 1 allein. Es ist der vertikal nach unten geförderte Bahnanfang der zu überführenden zweiten Teilbahn B2 vor dem Einlaufen in die Überführvorrichtung 2 angedeutet. Das Umlenkmittel 16 wird im Falle einer Rollenrotationsdruckmaschine durch eine Registerwalze gebildet, die in Figur 2 in ihren beiden Endstellungen eingezeichnet ist. Das Überführband 3 läuft um drei Bandumleitwalzen 7, 8 und 9 sowie über eine Spannrolle, die an einem verstellbaren Arm 4 gehalten ist, um. Die erste Bandumleitwalze 7 ist in unmittelbarer Nähe des im Ausführungsbeispiel durch eine Bahn-Umleitwalze gebildeten Aufgabemittels 17 angeordnet. Die drei Bandumleitwalzen 7, 8 und 9 bilden eine Dreiecksanordnung. Im Bereich eines Obertrums des Überführbands 3 zwischen den Walzen 7 und 8 ist das Überführband 3 gegen die Registerwalze 16 angestellt, so daß es diese Registerwalze 16 von unten im wesentlichen in dem Bereich, in dem die überführte zweite Teilbahn B2 die Registerwalze 16 umschlingt, ebenfalls umschlingt. Die Registerwalze 16 und das im Umlenkbereich anliegende Obertrum des Überführbands 3 bilden eine Art Einlauftrichter für den von oben angeförderten Bahnanfang der Teilbahn B2. Der angeförderte Bahnanfang läuft zunächst auf das Obertrum des Überführbands 3. Anschließend wird es zwischen die Registerwalze 16 und dieses Obertrum eingezogen und zwischen beiden geklemmt um die Registerwalze 16 gefördert. Nach dem Umlenken liegt der Bahnanfang frei auf dem Obertrum in dessen Abschnitt zwischen der Registerwalze 16 und der ersten Bandumleitwalze 7 auf. Durch Förderung zwischen der Registerwalze 16 und dem Überführband 3 hindurch gelangt der Bahnanfang auf dem Überführband 3 aufliegend zur ersten Bandumleitwalze 7.Figure 2 shows the web transfer device 2 of Figure 1 alone. The vertically downward conveyed beginning of the web of the second partial web B 2 to be transferred is indicated before it enters the transfer device 2. In the case of a web-fed rotary printing press, the deflecting means 16 is formed by a register roller, which is shown in FIG. 2 in its two end positions. The transfer belt 3 runs around three belt guide rollers 7, 8 and 9 as well as via a tensioning roller which is held on an adjustable arm 4. The first belt diverting roller 7 is arranged in the immediate vicinity of the feed means 17 formed in the exemplary embodiment by a web diverting roller. The three belt guide rollers 7, 8 and 9 form a triangular arrangement. In the area of an upper run of the transfer belt 3 between the rollers 7 and 8, the transfer belt 3 is positioned against the register roller 16, so that it essentially registers this register roller 16 from below in the area in which the transferred second web B 2 wraps around the register roller 16. also wraps around. The register roller 16 and the upper run of the transfer belt 3 in the deflection area form a kind of feed hopper for the web start of the partial web B 2, which is conveyed from above. The conveyed start of the web initially runs onto the upper run of the transfer belt 3. It is then drawn in between the register roller 16 and this upper run and conveyed between the two around the register roller 16. After the deflection, the beginning of the web lies freely on the upper run in its section between the register roller 16 and the first belt deflection roller 7. By conveying between the register roller 16 and the transfer belt 3, the beginning of the web, lying on the transfer belt 3, reaches the first belt diversion roller 7.

Zwischen dem Überführband 3, das um die erste Bandumleitwalze 7 läuft, und der dieser Bandumleitwalze 7 nachgeordneten Bahn-Umleitwalze 17 ist ein rechenförmiges Bahnauflagemittel 11 angeordnet, über das der Bahnanfang nahezu stetig auf die nachgeordnete Bahn-Umleitwalze 17 gefördert wird. Mit seinen rechenförmigen Fingern greift das Bahnauflagemittel 11 in die entsprechenden umlaufenden Nuten der Bahn-Umleitwalze 17 ein. Im Ausführungsbeispiel ist das Bahnauflagemittel auf der Drehachse der Bandumleitwalze 7 drehgelagert.Between the transfer belt 3, which runs around the first belt guide roller 7, and the this band diverting roller 7 downstream web diverting roller 17 is a rake-shaped Web support means 11 arranged, via which the beginning of the web almost continuously on the downstream web guide roller 17 is promoted. With its rake-shaped The web support means 11 engages fingers in the corresponding circumferential grooves the web diverter roller 17 a. In the exemplary embodiment, the web support means is on the axis of rotation of the belt deflection roller 7 rotatably.

Das Überführband 3 ist gegen die Registerwalze 16 anstellbar bzw. durch Abschwenken von dieser abstellbar. Das An- und Abstellen erfolgt durch Schwenken um die Drehachse der angetriebenen Bandumleitwalze 7. In Figur 2 ist das Überführband 3 in durchgezogener Linie in Anstellung zur Registerwalze 16 und in gestrichelter Linie in seiner davon abgestellten Stellung dargestellt.The transfer belt 3 can be set against or through the register roller 16 Swiveling away from this. Switching on and off takes place by swiveling about the axis of rotation of the driven belt deflection roller 7. In FIG Conveyor belt 3 in a continuous line in line with the register roller 16 and in Dashed line shown in its parked position.

Durch das Anstellen gegen die Registerwalze 16 wird das Überführband von der Registerwalze 16 mitangetrieben. In einer anderen, ebenfalls bevorzugten Ausführungsform wird die Bandumleitwalze 7 von einem eigenen Motor angetrieben.By moving against the register roller 16, the transfer belt from the Register roller 16 also driven. In another, also preferred embodiment the belt deflection roller 7 is driven by its own motor.

Die zweite Bandumleitwalze 8 und die dritte Bandumleitwalze 9 sind zum Zwecke des Anstellens und Abstellens des Überführbands 3 an bzw. von der Registerwalze 16 an einer Anstellvorrichtung 15, die um eine Achse 14 schwenkbar angeordnet ist, befestigt. Die Anstellvorrichtung 15 wird im Ausführungsbeispiel durch einen einfachen Balken 5 gebildet, der einen Anschlag 13 zur Begrenzung der Schwenkbewegung der Anstellvorrichtung 15 gegen die Registerwalze 16 aufweist. Die zweite Bandumleitwalze 8 ist unmittelbar an dem Balken 5 drehbar angebracht, während die dritte Bandumleitwalze 9 an einem winkelig von diesem Balken 5 abstehenden Tragarm 12 drehbar gehalten ist. Der die Spannrolle für das Überführband 3 tragende Arm 4 ist an dem Balken 5 zum Einstellen der gewünschten Bandspannung schwenkbar angebracht. Die Schwenkbewegung der Anstellvorrichtung 15 um die Drehachse 14 und damit auch die Schwenkbewegung des Überführbands 3 um die erste Bandumleitwalze 7 wird durch einen Stellzylinder 6 bewirkt, der an den Balken 5 angelenkt ist.The second belt guide roller 8 and the third belt guide roller 9 are for the purpose starting and placing the transfer belt 3 on or off the register roller 16 on an adjusting device 15 which is arranged pivotably about an axis 14, attached. The adjusting device 15 is in the embodiment by a simple bar 5 formed, the stop 13 to limit the pivoting movement of the adjusting device 15 against the register roller 16. The second Bandumleitwalze 8 is directly rotatably attached to the beam 5, while the third belt deflection roller 9 on an angularly protruding from this beam 5 Support arm 12 is rotatably held. The tension roller for the transfer belt 3 supporting arm 4 is on the beam 5 for setting the desired band tension pivotally attached. The pivoting movement of the adjusting device 15 around the Axis of rotation 14 and thus also the pivoting movement of the transfer belt 3 around first belt deflection roller 7 is effected by an actuating cylinder 6, which on the bar 5 is articulated.

Das Überführband 3 wird in Längsrichtung der Registerwalze 16 gesehen durch mehrere parallel nebeneinander laufende Bandstreifen gebildet. Die Bandumleitwalzen 7, 8, 9 und die Anstellvorrichtung 15 sind entsprechend ausgebildet.The transfer belt 3 is seen in the longitudinal direction of the register roller 16 several strips of tape running parallel to one another are formed. The belt diversion rollers 7, 8, 9 and the adjusting device 15 are designed accordingly.

In der abgestellten Stellung ist das Überführband 3 in etwa dreieckförmig um die drei Bandumleitwalzen 7, 8 und 9 geführt. In Anstellung an die Registerwalze 16 wird das Band 3 im Bereich des Obertrums zwischen der ersten Bandumleitwalze 7 und der dritten Bandumleitwalze 9 eingedrückt und umschlingt so teilweise die Registerwalze 16. In Anstellung an die Registerwalze 16 nimmt das Überführband 3 in etwa die Form eines liegenden "L" ein. Der kurze, nach oben weisende Schenkel dieses "L" bildet zusammen mit der Registerwalze 16 den Einlauf für die Teilbahn B2 und die Umschlingung zur Registerwalze 16 und der lange, in etwa horizontal liegende oder zur Horizontalen leicht geneigte Schenkel dieses "L" weist in gerader Linie zu der als Aufgabemittel dienenden Bahn-Umleitwalze 17.In the parked position, the transfer belt 3 is guided approximately triangularly around the three belt guide rollers 7, 8 and 9. In line with the register roller 16, the belt 3 is pressed in in the region of the upper strand between the first belt guide roller 7 and the third belt guide roller 9 and thus partially wraps around the register roller 16. In the position against the register roller 16, the transfer belt 3 takes approximately the shape of a lying " L "a. The short, upward-pointing leg of this "L" forms, together with the register roller 16, the inlet for the partial web B 2 and the looping to the register roller 16, and the long, approximately horizontally lying or slightly inclined leg of this "L" points in straight line to the web diversion roller 17 serving as the feeding means.

Indem das Überführband 3 von der Registerwalze 16 abgestellt und somit außer Eingriff dazu gebracht werden kann, was in dem Moment erfolgt, in dem der Bahnanfang der überführten zweiten Teilbahn B2 von den der Bahn-Umleitwalze 17 nachgeordneten Walzen des Zugwalzenpaares 18 übernommen worden ist, kann verhindert werden, daß möglicherweise auf das Überführband 3 übertragene Druckfarbenreste von dem Überführband 3 wieder auf die bereits überführte Teilbahn B2 zurückübertragen werden. Nach der Überführung der Teilbahn B2 bzw. nach dem Zusammenführen mit der Teilbahn B1 läuft die überführte Teilbahn B2 ohne das abgestellte Überführband 3 zu berühren um die Registerwalze 16 und die nachgeordnete Bahn-Umleitwalze 17. Nachdem das Überführband 3 abgestellt bzw. außer Eingriff zu der Registerwalze 16 gebracht worden ist, kann der Antrieb der ersten Bandumleitwalze 7 abgeschaltet werden. In dieser Stellung kann das antriebslose oder antriebslos geschaltete Überführband 3 beispielsweise gewartet, insbesondere gereinigt, werden.By turning the transfer belt 3 off the register roller 16 and thus disengaging it, which occurs at the moment when the beginning of the web of the transferred second partial web B 2 has been taken over by the rollers of the pair of draw rollers 18 downstream of the web guide roller 17, can be prevented that any ink residues transferred to the transfer belt 3 are transferred back from the transfer belt 3 to the already transferred partial web B 2 . After the transfer of the partial web B 2 or after the combination with the partial web B 1 , the transferred partial web B 2 runs without touching the parked transfer belt 3 around the register roller 16 and the downstream web guide roller 17. After the transfer belt 3 is parked or out Has been brought into engagement with the register roller 16, the drive of the first belt guide roller 7 can be switched off. In this position, the drive belt 3 which is not driven or switched off can be serviced, in particular cleaned, for example.

Figur 3 zeigt eine erste Ausführungsalternative für eine erfindungsgemäße Überführvorrichtung. Die Überführvorrichtung nach Figur 3 unterscheidet sich von der nach Figur 2 lediglich dadurch, daß keine gesonderte Antriebswalze, nämlich die Bandumleitwalze 7, vorgesehen ist. Das Überführband 3 läuft im Ausführungsbeispiel nach Figur 3 um die Bahn-Umleitwalze 17 um, die somit gleichzeitig die Funktion einer angetriebenen Bandumleitwalze übernimmt. Das Überführband 3 ist dementsprechend um die Drehachse der Bahn-Umleitwalze 17 zur Registerwalze 16 an- und davon abstellbar. Ansonsten sind die Konstruktion und die Funktionsweise dieser Ausführungsalternative zu der nach Figur 2 gleich.Figure 3 shows a first alternative embodiment for an inventive Transfer device. The transfer device according to Figure 3 differs from that of Figure 2 only in that no separate drive roller, namely the Belt diversion roller 7 is provided. The transfer belt 3 runs in the embodiment according to Figure 3 around the web diverter roller 17, which thus simultaneously the Function of a driven belt guide roller takes over. The transfer belt 3 is correspondingly about the axis of rotation of the web diversion roller 17 to the register roller 16 switched on and off. Otherwise, the construction and functionality this embodiment alternative to that according to FIG. 2 is the same.

In Figur 4 ist eine mechanisch besonders einfache Überführvorrichtung 2 dargestellt. Hierbei ist zu der Registerwalze 16 benachbart ein starres Leitmittel 5, im Ausführungsbeispiel ein einfaches Umlenkblech, angeordnet. Das Leitmittel 5 bildet wiederum zusammen mit der Registerwalze 16 einen trichterförmigen Einlauf für den angeförderten Bahnanfang der zweiten Teilbahn B2. Der angeförderte Bahnanfang stößt zunächst auf eine der Registerwalze 16 zugewandte, gerundete Umlenkfläche des Umleitmittels 5 und gleitet auf dieser Umlenkfläche bei seiner weiteren Förderung auf das Überführband 3.A mechanically particularly simple transfer device 2 is shown in FIG. A rigid guide means 5, in the exemplary embodiment a simple deflection plate, is arranged adjacent to the register roller 16. The guide means 5 in turn forms, together with the register roller 16, a funnel-shaped inlet for the conveyed start of the second partial web B 2 . The conveyed start of the web initially encounters a rounded deflecting surface of the deflecting means 5 facing the register roller 16 and slides on this deflecting surface during its further conveyance onto the transfer belt 3.

Ein oberes Ende des Leitmittels 5 weist geneigt zu dem einlaufenden Bahnanfang. Im weiteren Verlauf verläuft die Umlenkfläche des Leitmittels in etwa konzentrisch zur Oberfläche der Registerwalze 16. Ein unteres Ende des Leitmittels 5 ragt rechenförmig zwischen die Bandstreifen des Überführbands 3, so daß der Bahnanfang ständig von unten unterstützt ist.An upper end of the guide means 5 is inclined to the incoming web start. In the further course, the deflecting surface of the guide means runs approximately concentrically to the surface of the register roller 16. A lower end of the guide means 5 protrudes computationally between the belt strips of the transfer belt 3, so that the beginning of the web is constantly supported from below.

Die Überführung des Bahnanfangs auf dem Überführband 3 zur nachgeordneten Bahn-Umleitwalze 17 erfolgt wie im Ausführungsbeispiel nach Figur 3.The transfer of the beginning of the path on the transfer belt 3 to the downstream one Web diversion roller 17 takes place as in the exemplary embodiment according to FIG. 3.

Das Überführband nach Figur 4 ist nicht schwenkbar. Es läuft lediglich um die beiden ortsfest gelagerten Band-Umleitwalzen 17 und 8 sowie um die Spannrolle 4. Diese Ausführungsvariante zeichnet sich durch ihre Einfachheit und ihre vergleichsweise günstigen Anschaffungskosten aus.The transfer belt according to Figure 4 is not pivotable. It's just about that two stationary belt guide rollers 17 and 8 as well as around the tension pulley 4. This variant is characterized by its simplicity and its comparative low acquisition costs.
