Mit Hilfe der hier vorgeschlagenen Lösung soll die Abweichung der Lage von Querperforationen auf der Innen- und der Außenseite von Falzexemplaren dadurch korrigiert werden, daß die Lage einer außen am Exemplar ausgebildeten Querperforation in bezug auf eine innen am Falzexemplar ausgebildete Perforation verschoben ist. Dazu ist in einem Falzapparat ein mit dreifach-großem Durchmesser ausgeführter Falzzylinder vorgesehen, dessen Rotation an einen mit einfachem Durchmesser ausgeführten Zylinder übertragen wird, wobei zwischen besagten Zylindern eine Drehwinkelveränderungseinheit vorgesehen ist. Diese umfaßt ein erstes Zugwalzenpaar, ein Aufnahmezylinder einfachen Durchmessers, ein weiteres Zugwalzenpaar sowie ferner ein Doppelzahnrad ausgeführt in zweifach großem Durchmesser.

erhebliche Vereinfachung der Verstellvorrichtung für die Änderung der Phasenlage der
Perforierbrücken während des Maschinenlaufs relativ zum Perforierzylinder erzielen,
andererseits ist der Antrieb der Perforierbrücken erheblich vereinfacht. Zudem kann mittels
der erfindungsgemäß vorgeschlagenen Lösung die Einstellung der Perforiertiefe, i.e. des
Durchdringungsgrades der Perforationen insbesondere für mehrlagige Materialbahnen
vereinfacht werden.According to the invention the object is achieved by the features of patent claim 1.
The advantages that can be achieved with the solution according to the invention are diverse in nature.

Ein Perforierwerkzeug kann am Umfang eines Perforierzylinders stationär aufgenommen sein und mit einer am gegenüberliegenden Zylinder ebenfalls stationär gelagerten Perforierleiste zusammenarbeiten. An einer darüber hinaus an dem Perforierzylinder vorgesehenen ersten Perforierbrücke kann ein Perforierwerkzeug aufgenommen sein, das in Umfangsrichtung zu Perforierzylinder verdrehbar ist. Dieses arbeitet mit einer am gegenüberliegenden Zylinder stationär gelagerten Perforierleiste zusammen, beispielsweise zur Erzeugung einer Querperforation im Falzmodus zweiter Querfalz. Besagte Perforierbrücke kann zudem ein weiteres Perforierwerkzeug aufnehmen, welches für die Perforation im Falzmodus Deltafalz bestimmt ist und an im Exemplar ausgebildeten Falzrücken des Deltafalzes Perforationen anbringt.A perforating tool can be held stationary on the circumference of a perforating cylinder be and with a stationary on the opposite cylinder Work the perforation bar together.

Die an den Perforierzylindern standardmäßig stationär aufgenommenen Perforierleisten für Deltafalz und zweiter Querfalz (Doppelparallelfalz) können ebensogut auch an weiteren Perforierbrücken aufgenommen sein, die koaxial an den Zylinderachsen der Perforierzylinder gelagert sind. Zur Verminderung der Antriebsleistung des für die relative Verstellung notwendigen Stellantriebs für die Perforierbrücken können die schalenartig die Perforierzylinder umgebenden Perforierbrücken in Lagerungen an den Zylinderachsen aufgenommen werden.The perforation bars for the perforation cylinders, which are stationary on the perforation cylinders as standard Delta fold and second cross fold (double parallel fold) can also be used on others Perforating bridges are included, which are coaxial to the cylinder axes of the Perforating cylinders are stored.

Bahnstränge bestehen können. Die Exemplare 12 werden vom Falzzylinder 9
übernommen, an dessen Umfangsfläche 11 transportiert und durch Aktivieren des
Falzmessers 10, welches aus dem Umfang 11 des Falzzylinders 9 ausfährt, in die
Falzklappen eines hier nicht näher dargestellten mit dem Falzzylinder 9
zusammenarbeitenden Falzklappenzylinder eingestoßen. Demnach entsteht der Falzrücken
15 zwischen den Enden 13 und 14 des Exemplars 12, wodurch der erste Quer- bzw. erste
Parallelfalz gebildet wird. Durch einen hier nicht näher gezeigten Übergang der gefalzten
Exemplare 12 an einen weiteren Falzzylinder 16, wobei der Exemplarübergang nicht
Gegenstand der vorliegenden Erfindung ist, erfolgt eine Aufnahme des Exemplars 12 an
dessen Umfangsfläche 18 und die sich daran anschließende Ausbildung des zweiten
Querfalzes durch Ausfahren des Falzmessers 17 und Falzung des bereits einmal
quergefalzten Exemplars 12. Es entsteht ein doppelt quergefaltetes Exemplar 22 mit Enden
24 und 25, wobei am zweiten Querfalz (Doppelparallelfalz) der Falzrücken 23 ausgebildet
ist.After the perforation has taken place, the end of the leading end in the web running direction 2

Im Deltafalzmodus wird das Exemplar im Vergleich zum Doppelparallelfalzmodus
zweimal gefalzt, jedoch an verschiedenen Stellen, während bei Doppelparallelfalz je nach
eingestelltem Überfalz eine beim ersten und zweiten Querfalz erfolgende hälftige Falzung
am Exemplar 12 erfolgt, wodurch ein Exemplar 22 entsteht.
Nach erfolgter Querfalzung, sei es im Deltafalzmodus oder im Doppelparallelfalzmodus,
werden die solcherart gefalzten Exemplare 12, 22 über einen Transportzylinder 20 zu einer
gegebenenfalls vorgesehen zweiten Längsfalzeinrichtung transportiert, oder direkt zur
Auslage gebracht.In delta fold mode, the copy is compared to double parallel fold mode

Fig. 2 zeigt die Seitenansicht auf ein Perforierzylinderpaar 3, 4, wobei zwischen den
Umfangsflächen 33 und 34 der Perforierzylinder 3, 4 ein Perforierspalt 26 für die das
Perforierzylinderpaar 3, 4 passierende Materialbahn 1 vorgegeben ist. Je nach Dicke der zu
verarbeitenden Materialbahn 1 kann der Perforierzylinder 4 näher an den Umfang des
festgelagerten Perforierzylinders 3 angestellt oder weiter von diesem abgestellt werden.
dadurch läßt sich die Durchdringungstiefe der zu erzeugenden Perforationen in den die
Materialbahn 1 bildenden Bahnlagen einstellen und gegebenenfalls verändern.Fig. 2 shows the side view of a pair of perforating
Koaxial zu den Zylinderachsen 31, 32 der Perforierzylinder 3 und 4 sind in dem
dargestellten Ausführungsbeispiel je Perforierzylinder 3, 4 eine Perforierbrücke 27, 28
vorgesehen, auf der variabel positionierbare Perforierwerkzeuge aufgenommen sind. Es
können pro Perforierzylinder 3, 4 auch zwei Perforierbrücken vorgesehen werden, vgl.
27.1 und 28.1 in Fig. 4. An den in Fig. 2 dargestellten Perforierbrücken 27 , 28 befinden
sich die Perforierwerkzeuge 38.1 für den Deltafalz bzw. das Perforierwerkzeug 36.1 für
den zweiten Querfalz. Diese arbeiten mit den stationär am Umfang 34 des verstellbar
gelagerten Perforierzylinders 4 vorgesehenen Perforierleisten 36.2 für den zweiten
Querfalz bzw. 38.2 für den Deltafalz zusammen.Coaxial to the
Am Umfang 33, 34 der beiden Perforierzylinder 3, 4 stationär aufgenommen sind die
Perforierwerkzeuge 35.1 und die damit zusammenarbeitende Perforierleiste 35.2 für die
Ausbildung einer Perforation im Bereich eines ersten Querfalzes am Exemplar. Stationär
am festgelagerten Perforierzylinder 3 ist die Perforierleiste 37.2, die ihrerseits mit dem an
der weiteren Perforierbrücke 28 aufgenommenen Perforierleiste 37.1 für den zweiten
Querfalz zusammenarbeitet
Der Perforierzylinder 3 rotiert in Drehrichtung 29 bezogen auf den Perforierspalt 26,
während der verstellbar gelagerte Perforierzylinder 4 gleichsinnig zu diesem rotiert, so daß
sich ein kontinuierlicher Bahnvorschub durch den Perforierspalt 26 einstellt. Die
Perforierbrücke 28 ist bezogen auf die Umfangsfläche 34 des Perforierzylinders 4 entgegen
der Drehrichtung des Perforierzylinders 4 in Drehrichtung 30 verstellbar.On the
Die hier stationär angeordnet wiedergegebenen Perforierleisten 36.2, 37.2 sowie 38.2
könnten (vgl. Fig. 2) auch am weiteren die Umfangsflächen 33, 34 der Perforierzylinder 3,
4 schalenartig umgreifenden Perforierbrücken 27.1, 28.1 (Fig. 4) aufgenommen werden
und damit ebenfalls relativ verstellbar sein oder alternativ verstellbar sein, simultan mit
Perforierwerkzeugen 36.1, 37.1, 38.1, die an den Perforierbrücken 27, 28 aufgenommen
sind.The perforating strips 36.2, 37.2 and 38.2 shown here arranged in a stationary manner

In der Ausführungsvariante gemäß Fig. 3 ist ein Perforierzylinder 3, 4 jeweils mit einer
Perforierbrücke 27, 28 versehen. Die Perforierbrücken 27, 28 sind in Lagerungen 43, 44
auf Zylinderzapfen der Zylinderachsen 31, 32 aufgenommen und mit einer eine
Verstellung in Umfangsrichtung der Perforierzylinder 3 und 4 ermöglichenden
Verzahnung 47 versehen. Diese kämmt mit einer Außenverzahnung 46 eines
Übertragungselements 45, welches als ein auf der Zylinderachse 31 bzw. 32 verschiebbare
oder verdrehbare Kulissenführung ausgebildet werden kann.3 is a perforating
Beide Kulissenführungen 45 auf den Zylinderachsen 31, 32 sind mit einer Verstelleinheit
48 verbunden, mit der eine Relativverstellung der Perforierbrücken 27, 28 zu den
Umfangsflächen 33, 34 der Perforierzylinder 3, 4 erfolgen kann. Durch die Integration
einer Ausgleichseinheit 49 in die Gleitführung 50 zwischen den Übertragungselementen 45
auf den Zylinderachsen 31, 32 läßt sich eine Veränderung des Perforierspaltes 26
unabhängig von der Phasenlagenverstellung der Perforierbrücken 27, 28 an den
Perforierzylindern 3 und 4 zueinander erzielen. Dies wird dadurch unterstützt, daß der
verstellbare Perforierzylinder 4 über eine Gelenkwelle 42 mit seinem Antriebszahnrad 41
verbunden ist, welches seinerseits über das Antriebszahnrad 40 des Perforierzylinders 3
angetrieben wird. Angesichts der Gelenkwelle 42 kann eine Relativverstellung des
verstellbaren Zylinders 4 in Bezug auf den Perforierspalt 26 problemlos erfolgen. Die
miteinander via Gleitführung 50 und Ausgleichseinheit 49 verbundenen Kulissenführungen
45 sind gemeinsam zueinander positionierbar, da eine korrekte Einstellung von
Perforierwerkzeugen 36.1, 38.1 zu den Perforierleisten 36.2, 38.2 je nach Falzmodus
gewährleistet sein muß. Erfolgt eine Verstellung der Drehlage einer Perforierbrücke, wird
die dazu korrespondierende Perforierleisten aufnehmende Perforierbrücke
falzmodusabhängig automatisch mitverstellt.Both link guides 45 on the cylinder axes 31, 32 are with an
Fig. 4 zeigt die Kinematik eines Perforierzylinderpaares, wobei an jedem der Zylinder 3, 4
zwei Perforierbrücken 27, 27.1 bzw. 28, 28.1 ausgebildet sind. Die Perforierbrücken 27,
27.1, 28 und 28.1 sind allesamt in Lagerungen 43, 44 bzw. 54, 55 an den Zylinderachsen
31, 32 aufgenommen. Im Unterschied zum Ausführungsbeispiel gemäß Fig. 3 befinden
sich an den hier dargestellten Übertragungselementen 51 zwei Außenverzahnungen 46, 52,
die mit jeweils korrespondierenden Verzahnungen 47, 53 der Perforierbrücken 27, 27.1
sowie 28 und 28.1 zusammenarbeiten.4 shows the kinematics of a pair of perforating cylinders, with each of the
Es ist eine beiden Kulissenführungen zugeordnete Verstelleinheit 48 analog zur
Ausführungsform gemäß Fig. 3 vorgesehen, die auf die Übertragungselemente 51 einwirkt,

beschriebene Ausgleichseinheit 49 in die Gleitführung 50 integriert ist.It is an
Beim Ausführungsbeispiel gemäß Fig. 4 sind die in Fig. 2 stationär am Umfang 33, 34 der
Perforierzylinder 3, 4 aufgenommenen Perforierleisten 36.2, 37.2 und 38.2 ebenfalls auf
Perforierbrücken 27.1, 28.1 gelagert, so daß diese ebenfalls relativ zu den Umfangsflächen
der Perforierzylinder 3, 4 in Umfangsrichtung verstellbar sind, so daß eine gleichzeitige
Bewegung der Perforierleisten 36.2, 37.2, 38.2 und der Perforierwerkzeuge 36.1, 37.1 und
