Fussbeschnitt bestehen aus zwei einander gegenüberstehenden Messern 14, 15 zwischen denen die vereinzelten Druckprodukte 2 von der Fördervorrichtung 3 angetrieben hindurchführbar sind. Die Messer 14, 15 werden durch eine anschliessend zu beschreibende Antriebsvorrichtung 16 in eine zur Ebene der Druckprodukte 2 im wesentlichen senkrechte Schneideingriffsbewegung versetzt, derart, dass die mit ihrer Schneidrichtung parallel zur Förderrichtung der Fördervorrichtung 3 angeordneten sowie gegenseitig geführten Messer 14, 15 während dem Schneideingriff zusätzlich mit den Druckprodukten 2 gleichsinnig bewegt werden.
Dabei sind die Messer in der Form länglicher Messerklingen ausgebildet und werden wie erwähnt von der Antriebsvorrichtung 16 parallel zu der Förderrichtung hin- und herbewegt. Hierzu sind Kurbeltriebe 17 und 18 vorgesehen, die jeweils einem Messer 14, 15 zugeordnet sind.
Beide jeweils einem Messer 14, 15 zugeordneten Kurbeltriebe 17, 18 zusammen bilden eine Antriebsvorrichtung 16 der Schneidvorrichtung 4, 4' wobei jeder Kurbeltrieb 17, 18 zwei in Förderrichtung der Fördervorrichtung 3 beabstandete Kurbeln 19, 20 bzw. 21, 22 aufweist, an denen jeweils eines der mit ihrer Schneidrichtung parallel zur Förderrichtung angeordneten Messer 14, 15 endseitig angelenkt ist.
Die gleichförmigen Schwingungsbewegungen der Kurbeltriebe 17, 18 entsteht durch eine winkelgleiche Drehbewegung zweier einem Messer 14, 15 zugeordneter Kurbeln 19, 20 resp. 21, 22, wobei dafür und den gleichen Drehsinn ein zwischen den beiden Kurbeln 19, 20 oder den Kurbeln 21, 22 angeordnetes gemeinsames Antriebsrad 23 vorgesehen ist. Im dargestellten Ausführungsbeispiel ist gemäss den Fig. 1 und 2 dieses Antriebsrad 23 den Kurbeln 19, 20 zugeordnet.
In Fig. 3 ist ersichtlich, dass bei den Schneidvorrichtungen 4, 4' für Kopf- bzw. Fussbeschnitt die Kurbeltriebe 17, 18 durch an den Kurbelachsen 24 bis 27 befestigte Zahnräder 28 bis 31 gleichen Teildurchmessers und Zähnezahl ausgebildet sind.
The cutting device 4, 4 'is designed, as shown, for the head or foot trimming of a printed product 2, the latter being aligned with the predetermined cutting lines before the cut by a centering device 11 consisting of circumferential belts and acting laterally on the printed products 2 and one Accelerating device 13 superimposed on the conveying speed, comprising rotating belts (not shown), are placed one behind the other against stops 12 on the conveying device 3 formed by rotating conveyor chains. The cutting devices 4, 4 '5 for head or. The foot trimming consists of two opposing knives 14, 15 between which the separated printed products 2 can be passed, driven by the conveying device 3. The knives 14, 15 are set by a drive device 16 to be described subsequently in a cutting engagement movement which is essentially perpendicular to the plane of the printed products 2, such that the knives 14, 15, which are arranged with their cutting direction parallel to the conveying direction of the conveying device 3 and are mutually guided, during the cutting engagement can also be moved in the same direction with the printed products 2.
The knives are designed in the form of elongated knife blades and, as mentioned, are moved back and forth by the drive device 16 parallel to the conveying direction. For this purpose, crank drives 17 and 18 are provided, each of which is assigned to a knife 14, 15.
Both crank drives 17, 18 each associated with a knife 14, 15 together form a drive device 16 of the cutting device 4, 4 ', each crank drive 17, 18 having two cranks 19, 20 and 21, 22 spaced apart in the conveying direction of the conveying device 3, on each of which one of the knives 14, 15 arranged parallel to the conveying direction with its cutting direction is articulated at the end.
The uniform vibratory movements of the crank mechanisms 17, 18 are created by an angularly rotating movement of two cranks 19, 20 assigned to a knife 14, 15 respectively. 21, 22, a common drive wheel 23 being provided between the two cranks 19, 20 or the cranks 21, 22 for this purpose and the same direction of rotation. In the illustrated embodiment, this drive wheel 23 is assigned to the cranks 19, 20 according to FIGS. 1 and 2.
In Fig. 3 it can be seen that in the cutting devices 4, 4 'for head or foot trimming, the crank drives 17, 18 are formed by gear wheels 28 to 31 of the same part diameter and number of teeth attached to the crank axes 24 to 27.

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 cranks 19, 20 of a knife 14 relative to the cranks 21, 22 of the opposite knife 15 different rotational positions on the crank axis 24, 25, respectively. 26, 27, that is to say that the (lower) knife 15 reaches its highest (culmination) position before the (upper) knife 14 reaches its lowest position (maximum cutting intervention). The cranks 19, 20 assigned to the knife 14 are driven in a controlled manner with regard to the cutting engagement movement of the cutting device 4, 4 ', 5, in a controlled manner after the cranks 21, 22 assigned to the knife 15.
This wake is due to the mutual rotatability of the cranks 20, 22 and. 19, 21 by means of gears 29, 31 respectively. 28, 30 possible or adjustable and lockable and can take place in coordination with the properties of the printed products 2 and the cutting process.
The fact that the cranks 19, 21 and 20, 22 opposite one another on the printed products 2 or the knives 14, 15 and the conveying device 3 have approximately the same speed in their proximity range, one can speak of a resulting cutting distance on which the Cutting intervention takes place.

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.
Als Versteifungshilfe sind die umlaufenden, endlosen Bänder 35 der Fördervorrichtung 3 an einer Führungsvorrichtung 34 abgestützt
Der vollständigkeithalber weisen wir auf eine weitere, aus sich in einer Reihe folgenden Rollen 36 bestehenden Abstützvorrichtung 37 in der Längsmittelachse der Schneidanlage 1 und eine Führungsanordnung 38 für Anschlagförderkette 39 hin.
So that the printed products 2 lie still on the conveying device immediately before cutting, the conveying device 3, which consists of at least two laterally spaced, endlessly circulating belts, and the upper edge of the knife 15 during the cutting engagement of the cutting device 4, 4 ', 5 form an approximately coplanar level. FIG. 2 shows that the knife 15 has reached the coplanar plane with its upper edge, before reaching its highest position and immediately before the start of the cut, and then performs a counter-cutting movement by slightly lifting it. This possibility documents the adaptability of the cutting devices 4, 4 '5 to the selectable conditions when trimming the printed products.
In FIG. 2 it can also be seen that the knives 14, 15 form a cutting gap 32 narrowing in the conveying direction of the printed products 2, the feed angle of which can be changed by an adjusting and locking device 71, which is due to the properties of the printed products 2 to be cut. The flatter the feed gap, the higher the cutting and conveying performance acting on the printed products 2. For the adjustability of the knife 14, it is fastened to a bar 33 which is articulated on the cranks 19, 20 at both ends and which are provided with threaded holes along their length, in which screws rest, which penetrate vertical slots in the knife 5.
The circumferential, endless belts 35 of the conveying device 3 are supported on a guide device 34 as a stiffening aid
For the sake of completeness, we refer to a further support device 37 consisting of rollers 36 in a row in the longitudinal central axis of the cutting system 1 and a guide arrangement 38 for the stop conveyor chain 39.

Zur Minderung der durch die Kurbelbewegung entstehenden Unwucht in den Lagern und des verursachten Lärms, sind auf der einer Kurbel 19 bis 22 an der Kurbelachse 24 bis 27 gegenüberliegenden Seite ausgleichende Gegengewichte 40 befestigt.To reduce the imbalance caused by the crank movement in the camps and the noise caused, are on the a crank 19 to 22 on the crank axis 24 to 27 opposite Side counterweights 40 attached.

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 eingeleitet, durch eine Federkraft schliessen. Die Druckprodukte 2 werden sodann auf einem Führungstisch 43, der im Schneideingriffsbereich der Schneidvorrichtung 5 unterbrochen ist, durch letztere hindurchbewegt bzw. -gezogen.
4 and 5 convey a cutting device 5 which is provided for the front trimming of the printed products 2 and which connects to the continuous passage of the printed products 2 transferred by the cutting devices 4, 4 'for the head and foot trimming.
The transfer, which is preferably, but not in any case, cycle-based, is carried out by the conveying device 3, which extends beyond the cutting device 4, 4 'in the conveying direction, and a transporter 40 which cooperates with the latter at the discharge end thereof and can be actuated at uniform intervals by control devices on the circulating conveying chain 41 thereof Grippers 42 are attached. The arrangement and the interaction of the conveyor 3 with the conveyor 40 can be seen in FIGS. 1 and 5. The drive of the conveyor 40, which runs approximately in the vertical longitudinal center plane of the cutting system 1, is effected by the traction mechanism gear 9. The printed products 2 are pushed or fed by the conveying device 3 to the grippers 42, which are open in the take-over area or at the delivery point of the conveying device 3 and which are fed in by a control device when the printed product 2 is delivered, and close by a spring force. The printed products 2 are then moved or pulled through the latter on a guide table 43, which is interrupted in the cutting engagement area of the cutting device 5.

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 einen Federkraftspeicher 72 auf die Druckprodukte 2 gedrückt werden.
The cutting device 5 adjoining the cutting devices 4, 4 ′ differs from the former in that its knives 50, 51 are arranged with the cutting direction transverse to the conveying direction of the conveying device 3. This means that two cooperating crank drives 48, 49 and 48 ', 49' are in turn provided on each side of the conveying path of the printed products 2, which are connected to the opposite crank drives 48, 49 and 48 '49' by the knives 50, 51 , wherein the knives 50, 51 are attached to the actuators 44 to 47 articulated at the ends with the cranks of the crank drives 48, 49 and 48 '49' spaced apart in the conveying direction.
In contrast to the different angular positions of the cranks 19 to 22 in the synchronously driven crank drives 17, 18 and. 17 '18' for head or foot trimming of a printed product 2, the angles of the cranks 52 to 55 on the crank axes 56 to 59 are aligned approximately in pairs symmetrically opposite one another from the printed products 2, so that the knives 50, 51 have a cutting plane running transversely to the conveying direction form and the cutting operation takes place on a cutting path that is parallel to the conveying direction. The printed products 2 move at least approximately as fast as the knives 50, 51 on this cutting path, which do not change their vertical cutting position during their orbital movement.
The crossbeams 64, here the lower one, receiving the knives 50, 51 form a support for the printed products during cutting. To stabilize the printed products 2, according to FIG. 3, a holding-down device 65, which extends at least over the cutting section and presses the printed products 2 against the upper side of the beam 33, is provided with a plurality of press rollers lined up in the conveying direction, which are pressed against the printed products 2, for example against a spring force accumulator 72 will.

Der Antrieb der Schneidvorrichtung 5 wird über Antriebsritzel 60 eingeleitet und ein Zwischenrad 61 sorgt für eine gleichsinnige Drehung der Kurbeln 52, 53 bzw. 52' 53' und entsprechend gegensinnige bei den Kurbeln 54, 55 bzw. 54' 55' auf der gegenüberliegenden Seite des Transporteurs 40. Dieser besteht gemäss Fig. 5 aus zwei jeweils seitlich der senkrechten Längsmittelebene verlaufenden Transportketten 41, die durch einen quergerichteten, die Greifer 42 tragenden Distanzhalter 62 verbunden sind. Die ausserhalb des Schneidbereiches der Schneidvorrichtung 5 angeordneten Transportketten 41, sind an stationären Führungsstegen 63 abgestützt.The drive of the cutting device 5 is via drive pinion 60 initiated and an idler gear 61 ensures a same direction Rotation of the cranks 52, 53 and 52 '53' and the like opposite in the cranks 54, 55 and 54 '55' on the opposite side of the feed dog 40. This exists 5 from two each laterally of the vertical longitudinal median plane extending transport chains 41, which by a transverse spacers 62 carrying the grippers 42 are connected. The outside of the cutting area of the Cutting device 5 arranged transport chains 41 are on stationary guide webs 63 supported.

Fig. 6 zeigt eine Ausführungsform eines Greifers 42 in der geschlossenen Stellung, bei welcher der bewegliche Greiferteil 66 gegen den mit den Transportketten 41 verbundenen stationären Greiferteil 67 gepresst wird. Das Schliessen des Greifers 42 erfolgt durch Federkraft, gegen die mittels des an einer Steuerbahn auflaufenden Doppelhebels 68 der Greifer 42 gelüftet wird.Fig. 6 shows an embodiment of a gripper 42 in the closed position, in which the movable gripper part 66 against the stationary connected to the transport chains 41 Gripper part 67 is pressed. Closing the gripper 42 takes place by spring force, against which by means of a Control path running double lever 68 of the gripper 42 lifted becomes.
