Fig. 2 zeigt, dass die Kurbeln 19, 20 eines Messers 14 gegenüber
den Kurbeln 21, 22 des gegenüberliegenden Messers 15 unterschiedliche
Drehlagen an der Kurbelachse 24, 25 resp. 26,
27 aufweisen, d.h. dass das (untere) Messer 15 seine höchste
(Kulminations-) Lage erreicht, bevor das (obere) Messer 14
seine tiefste Position (max. Schneideingriff) erreicht. Die
dem Messer 14 zugeordneten Kurbeln 19, 20 sind hinsichtlich
der Schneideingriffsbewegung der Schneidvorrichtung 4, 4', 5
den dem Messer 15 zugeordneten Kurbeln 21, 22 nachlaufend gesteuert
angetrieben.
Dieser Nachlauf ist durch die gegenseitige Verdrehbarkeit der
Kurbeln 20, 22 resp. 19, 21 mittels Zahnräder 29, 31 resp. 28,
30 möglich bzw. ein- und feststellbar und kann in Abstimmung
mit den Eigenschaften der Druckprodukte 2 und des Schneidvorganges
erfolgen.
Dadurch, dass die sich an den Druckprodukten 2 gegenüberliegenden
Kurbeln 19, 21 und 20, 22 bzw. die Messer 14, 15 und
die Fördervorrichtung 3 in ihrem Näherungsbereich etwa die
gleiche Geschwindigkeit aufweisen, kann man von einer sich
ergebenden Schnittstrecke sprechen, auf welcher der Schneideingriff
erfolgt.Fig. 2 shows that the

The fact that the
Damit die Druckprodukte 2 unmittelbar vor dem Schneiden auf
der Fördervorrichtung ruhig liegen, bilden die Fördervorrichtung
3, die aus wenigstens zwei seitlich beabstandeten, endlos
umlaufenden Bändern besteht, und die Oberkante des Messers 15
während dem Schneideingriff der Schneidvorrichtung 4, 4', 5
eine etwa koplanare Ebene. Die Fig. 2 zeigt, dass das Messer
15 mit seiner Oberkante, vor dem Erreichen seiner höchsten
Stellung und unmittelbar vor Schnittbeginn die koplanare Ebene
erreicht hat und anschliessend durch ein geringes Anheben eine
Gegenschneidbewegung ausübt. Diese Möglichkeit dokumentiert
die Anpassungsfähigkeit der Schneidvorrichtungen 4, 4' 5 an
die wählbaren Gegebenheiten beim Beschneiden der Druckprodukte.
In Fig. 2 ist weiter erkennbar, dass die Messer 14, 15 einen
sich in Förderrichtung der Druckprodukte 2 verengenden
Schneidspalt 32 bilden, dessen Einzugswinkel durch eine Verstell- und Feststellvorrichtung 71 veränderbar ist, was auf
die Eigenschaften der zu schneidenden Druckprodukte 2 zurückzuführen
ist. Je flacher der Einzugsspalt, umso höher die auf
die Druckprodukte 2 einwirkende Schnitt- und Förderleistung.
Zur Verstellbarkeit des Messers 14 ist dieses an einem an den
Kurbeln 19, 20 beidenends angelenkten Balken 33 befestigt, die
auf ihrer Länge mit Gewindelöchern versehen sind, in denen
Schrauben ruhen, welche senkrechte Schlitze in dem Messer 5
durchsetzen.

Unersichtlich ist in der Zeichnung die Notwendigkeit einer für den Kopf- und Fussbeschnitt verschiedener Druckproduktformate vorgesehene Verstellbarkeit der Schneidvorrichtungen 4, 4' hinsichtlich ihres Abstandes quer zur Förderrichtung, wozu eine mit dem Maschinenständer quer zur Förderrichtung wirksame Führungsanordnung vorgesehen sein kann, an welcher die Schneidvorrichtungen 4, 4' beispielsweise durch Spindelantriebe einzeln oder gemeinsam verstell- und feststellbar sind.In the drawing is invisible the need for one the head and foot trimming of various printed product formats provided adjustability of the cutting devices 4, 4 ' in terms of their distance across the conveying direction, for what one effective with the machine stand at right angles to the conveying direction Guide arrangement can be provided on which the Cutting devices 4, 4 ', for example by spindle drives are individually adjustable or lockable.
Die Fig. 4 und 5 vermitteln eine zum frontseitigen Beschnitt
der Druckprodukte 2 vorgesehene Schneidvorrichtung 5, die an
den kontinuierlichen Durchlauf der von den Schneidvorrichtungen
4, 4' für den Kopf- und Fussbeschnitt überführten Druckprodukte
2 anschliesst.
Die Überführung, die vorzugsweise, aber nicht in jedem Fall
taktgebunden erfolgt, übernehmen die in Förderrichtung über
die Schneidvorrichtung 4, 4' hinausreichende Fördervorrichtung
3 und ein mit dieser an deren Abgabeende zusammenwirkender
Transporteur 40, an dessen umlaufender Transportkette 41 in
gleichmässigen Abständen durch Steuervorrichtungen betätigbare
Greifer 42 befestigt sind. Die Anordnungsweise und das Zusammenwirken
der Fördervorrichtung 3 mit dem Transporteur 40 kann
den Fig. 1 und 5 entnommen werden. Der Antrieb des etwa in der
senkrechten Längsmittelebene der Schneidanlage 1 verlaufenden
Transporteurs 40, wird vom Zugmittelgetriebe 9 aus bewirkt.
Die Druckprodukte 2 werden von der Fördervorrichtung 3 den im
Übernahmebereich bzw. an der Abgabestelle der Fördervorrichtung
3 falzvoraus offenen Greifern 42 zugeschoben bzw. zugeführt,
die bei zugestelltem Druckprodukt 2 von einer Steuervorrichtung

Die an die Schneidvorrichtungen 4, 4' anschliessende Schneidvorrichtung
5 unterscheidet sich von ersteren dadurch, dass
ihre Messer 50, 51 mit der Schneidrichtung quer zur Förderrichtung
der Fördervorrichtung 3 angeordnet sind. D.h., dass
an jeder Seite des Förderweges der Druckprodukte 2 wiederum
zwei zusammenwirkende Kurbeltriebe 48, 49 bzw. 48', 49' vorgesehen
sind, die mit den gegenüberliegenden Kurbeltrieben 48,
49 bzw. 48' 49' durch die Messer 50, 51 verbunden sind, wobei
die Messer 50, 51 an den endseitig mit den in Förderrichtung
beabstandeten Kurbeln der Kurbeltriebe 48, 49 bzw. 48' 49' angelenkten
Betätigungsgliedern 44 bis 47 befestigt sind.
Im Gegensatz zu den unterschiedlichen Winkelstellungen der
Kurbeln 19 bis 22 bei den ebenfalls synchron angetriebenen
Kurbeltrieben 17, 18 resp. 17' 18' für Kopf- bzw. Fussbeschnitt
eines Druckproduktes 2, sind die Winkel der Kurbeln 52
bis 55 an den Kurbelachsen 56 bis 59 etwa paarweise symmetrisch
gegenüberliegend von den Druckprodukten 2 ausgerichtet,
sodass die Messer 50, 51 eine quer zur Förderrichtung verlaufende
Schneidebene bilden und der Schneideingriff auf einer
parallel zur Förderrichtung sich ergebenden Schneidstrecke
erfolgt. Auf dieser Schneidstrecke bewegen sich die Druckprodukte
2 wenigstens annähernd so schnell wie die Messer 50, 51,
die während ihrer Umlaufbewegung ihre senkrechte Schnittstellung
nicht ändern.
Von den die Messer 50, 51 aufnehmenden Querbalken 64, hier der
untere, bilden eine Auflage der Druckprodukte beim Schneiden.
Zur Stabilisierung der Druckprodukte 2 ist gemäss Fig. 3 ein
zumindest über die Schneidstrecke sich erstreckender, die
Druckprodukte 2 gegen die Oberseite des Balkens 33 pressender
Niederhalter 65, mit mehreren in Förderrichtung nebeneinandergereihten
Pressrollen vorgesehen, die beispielsweise gegen
