Description

Die Erfindung betrifft eine Schneidmaschine gemäß dem Oberbegriff des Anspruches 1 . Eine solche Maschine ist in dem Dokument US 1 327 915 A offenbart.The invention relates to a cutting machine according to the preamble of claim 1 , Such a machine is described in US Pat. No. 1,327,915 disclosed.

Schneidmaschinen dieser Art sind schon lange bekannt und werden u.a. nach dem Sammelheften oder anderen Bindeverfahren für die Herstellung von Broschuren, Zeitschriften oder Büchern verwendet. Eine bekannte Schneidmaschine nach der US 1 327 915 A ist als Dreischneider ausgebildet. Zu einer ersten Schneidstation wird durch ein erstes, quer zur Förderrichtung der Druckerzeugnisse ein Frontschnitt ausgeführt, d.h. die Kante der offenen Seite auf das Endmass beschnitten. In der zweiten Schneidstation werden mit zwei sich gegenüberliegenden Messern der Kopf- und Fussschnitt an dem Druckerzeugnis ausgeführt. Insgesamt werden durch einen gemeinsamen Schneidhub der Messer zwei Druckerzeugnisse an der Front- oder Kopf- und Fusskante beschnitten. Jede Schneidstation weist verstellbare Anschläge auf und zwischen den Schneidstationen der Schneidmaschine ist eine Transportvorrichtung mit Bändern vorgesehen. Ähnliche Schneidmaschinen sind in den CH - A - 340479 und 531401 offenbart.Cutting machines of this type have been known for a long time and are used, inter alia, for saddle stitching or other binding processes for the production of brochures, magazines or books. A known cutting machine according to US 1 327 915 A is designed as a three-cutter. At a first cutting station, a front cut is made through a first, transverse to the conveying direction of the printed products, ie the edge of the open side is cut to the final dimension. In the second cutting station, the head and foot cuts are made on the printed product using two opposing knives. Overall, a common cutting stroke of the knives trims two printed products on the front or top and bottom edge. Each cutting station has adjustable stops and a conveyor with belts is provided between the cutting stations of the cutting machine. Similar cutting machines are disclosed in CH-A-340479 and 531401.

Eine wesentliche Anforderung an eine solche Schneidmaschine ist eine möglichst hohe Produktionsgeschwindigkeit bzw. Produktionsleistung. Diese wird insbesondere vom Format und der Dicke eines Druckerzeugnisses bzw. dem Gewicht des Druckerzeugnisses und der Beschaffenheit des Papiers beeinflusst. Dünne stabile Druckerzeugnisse können mit hohen Geschwindigkeiten gefahren werden. Dicke schwere und bauschige Druckerzeugnisse sind mit reduzierten Geschwindigkeiten zu verarbeiten. Die erreichbaren Produktionsgeschwindigkeiten werden im wesentlichen von der Breite der Druckerzeugnisse in Transportrichtung betrachtet bzw. von der Distanz zwischen den beiden Schneidstationen bzw. der Länge der dazwischenliegenden Transportstrecke beeinflusst, wobei die Frontkante bzw. offene Seite der Druckerzeugnisse durch ein quer zur Transportrichtung angeordnetes Messer einer Schneidstation, Kopf- und Fusskante dagegen durch zwei in Transportrichtung der Druckerzeugnisse ausgerichtete, sich gegenüberliegende Messer der nächsten Schneidstation gleichzeitig beschnitten werden.
Dabei bildet jeweils der stabilere Bund oder Rücken eines Druckerzeugnisses die Referenz- oder Bezugskante, nach welcher der Frontschnitt in einem bestimmten Abstand durchgeführt wird.
D.h., die Druckerzeugnisse werden mit dem Rücken resp. Bund voran gegen die der entsprechenden Schneidstation zugeordneten Anschläge transportiert. Hierbei ist zu beachten, dass die für Kopf- und Fussbeschnitt bestimmten Messer dem nach- oder vorlaufenden Druckerzeugnis keinen unerwünschten Schnitt oder sonstwie eine Beschädigung zufügen.
An essential requirement for such a cutting machine is the highest possible production speed or production output. This is influenced in particular by the format and the thickness of a printed product or the weight of the printed product and the nature of the paper. Thin, stable printed products can be run at high speeds. Thick, heavy and bulky printed matter can be processed at reduced speeds. The production speeds that can be achieved are essentially considered from the width of the printed products in the transport direction or influenced by the distance between the two cutting stations or the length of the intermediate transport path, the front edge or open side of the printed products being determined by a knife of a cutting station arranged transversely to the transport direction , Head and foot edges, on the other hand, can be trimmed at the same time by two opposite knives of the next cutting station, which are aligned in the transport direction of the printed products.
The more stable collar or spine of a printed product forms the reference or reference edge, according to which the front cut is carried out at a certain distance.
Ie, the printed products are with their backs resp. Bund first transported against the stops assigned to the corresponding cutting station. It should be noted here that the knives intended for head and foot trimming do not cause any unwanted cut or any other damage to the subsequent or leading print product.

Der Erfindung liegt die Aufgabe zugrunde, eine Schneidmaschine der genannten Gattung zu schaffen, die eine formatbezogen optimierte Produktionsgeschwindigkeit gestattet.The invention has for its object a cutting machine to create the type mentioned, which optimized a format-related Production speed allowed.

Diese Aufgabe ist durch die Merkmale des Anspruches 1, gelöst.This object is characterized by the features of claim 1, solved.

Dadurch ist bei der erfindungsgemässen Schneidmaschine eine Umstellung zwischen wenigstens zwei Formatbereichen möglich und die Distanz zwischen zwei Schneidstationen kann optimal an das zu bearbeitende Format eines Druckerzeugnisses angepasst werden. This is a change in the cutting machine according to the invention possible between at least two format ranges and the distance between two cutting stations can optimally match that format of a printed product to be edited.

Im Gegensatz zu den bekannten Schneidmaschinen mit festem Abstand der Schneidstationen, kann bei der erfindungsgemässen Schneidmaschine für ein gegebenes Druckerzeugnis die Distanz zwischen den Schneidstationen reduziert werden. Diese Reduktion erlaubt eine entsprechende Erhöhung der Geschwindigkeit der Druckerzeugnisse.
Die Formatanpassung ermöglicht zudem eine Optimierung der Verzögerung und Beschleunigung der Druckerzeugnisse zwischen den Schneidstationen. Schwierig zu bearbeitende Druckerzeugnisse, beispielsweise sehr dünne, empfindliche und leicht gleitende Druckerzeugnisse können optimal beschleunigt und verzögert werden. Zudem ist eine schonende Behandlung in der Schneidmaschine möglich.
In contrast to the known cutting machines with a fixed distance between the cutting stations, the distance between the cutting stations can be reduced in the cutting machine according to the invention for a given printed product. This reduction allows a corresponding increase in the speed of the printed products.
The format adjustment also enables optimization of the deceleration and acceleration of the printed products between the cutting stations. Printed products that are difficult to process, for example very thin, sensitive and easily sliding printed products, can be optimally accelerated and decelerated. Gentle treatment in the cutting machine is also possible.

Beim Beschneiden der Kanten liegen die Druckerzeugnisse 21 im Schneidbereich auf einer Leiste, die ein stationäres Gegenmesser bildet. Entlang dem Förderweg der Druckerzeugnisse 21 befindet sich im Schneidbereich von Kopf- und Fusskante eines Druckerzeugnisses 21 beidseits ein gegenüber dem für den Frontbeschnitt bestimmten beabstandeter Messerträger 75, an dem jeweils ein Messer 6, 6' für Kopf- oder Fussbeschnitt verstellbar befestigt ist. Der Zweck der Verstellbarkeit eines Messers 6, 6' am Messerträger 75 wird durch Fig. 1b veranschaulicht, in welcher der gleiche Vorgang wie in Fig. 1a an einem Druckerzeugnis 21 eines grösseren Formatbereichs ausgeführt wird. Der Abstand Y der Anschläge 40, 41 und die Position der Messer 6, 6' sowie deren Länge sind zur Optimierung der Produktionsleistung an das Druckerzeugnis 21 angepasst worden, d.h., es wurden längere Messer 6, 6' für den Kopf- und Fussbeschnitt eingesetzt, die in stromabwärtiger Richtung an den Messerträgern 75, so versetzt worden sind, damit bei dem gleichzeitigen Beschnitt zweier Druckerzeugnisse 21 keine Behinderung entsteht.
In Fig. 1c ist der Kopf-/Fussbeschnitt des breitesten Druckerzeugnisses 21 dargestellt, bei dem die Anschläge 40, 41 den grössten Abstand aufweisen bzw. die grösste Förderstrecke bilden. Hierzu wird das längste Messer 6, 6' in der weitest entfernten Position an dem Messerträger 75 verwendet.
1 a to 1 c schematically show a cutting machine 1 with two cutting stations A, B, of which A are provided for performing a front trimming on the open side of a printed product 21 which has been transported in the direction of arrow S and B for head and foot trimming.
1 a shows a printed product 21 from the format range with the smallest widths and from this range the narrowest printed product Bz min and widest Bz max. The illustration conveys a front trim carried out at the rear end of a leading printed product 21, which has been trimmed at the head and foot at the same time, which was previously trimmed at the front in the cutting station A.
The printed products 21 are fed to the cutting stations A, B in cycles and are trimmed in this rhythm on the front, in cutting station A by knives 2, and / or on the head and foot sides in cutting station B by opposing knives 6, 6 ', which move up and down , The stops 40, 41 form the reference or reference position and orientation of the printed products 21 in the cutting position and their distance Z can be adapted to the width of the printed product 21 trimmed on the front or to an optimal production output.
In addition, the stops 40, 41 are designed to be deliverable, so that after the trimming of the printed products 21, for their further transport by means of transport, which will be described later, they are placed in an inoperative position, for example below the conveying plane 74, which is indicated by a dash-dotted line , When the edges are trimmed, the printed products 21 lie in the cutting area on a strip which forms a stationary counter knife. Along the conveying path of the printed products 21, in the cutting area of the top and bottom edges of a printed product 21, there is a knife holder 75 on both sides that is spaced apart from the knife carrier 75 intended for the front trimming, on each of which a knife 6, 6 ′ for head or foot trimming is adjustably fastened. The purpose of the adjustability of a knife 6, 6 'on the knife carrier 75 is illustrated by FIG. 1b, in which the same process as in FIG. 1a is carried out on a printed product 21 of a larger format range. The distance Y between the stops 40, 41 and the position of the knives 6, 6 'and their length have been adapted to the printed product 21 in order to optimize the production output, ie longer knives 6, 6' were used for the head and foot trimming, which have been displaced in the downstream direction on the knife carriers 75, so that no hindrance arises when two printed products 21 are trimmed at the same time.
1c shows the head / foot trimming of the widest printed product 21, in which the stops 40, 41 have the greatest distance or form the largest conveying path. For this, the longest knife 6, 6 'is used in the most distant position on the knife carrier 75.

Die Figur 2 zeigt eine Schneidmaschine, der mit einem bekannten Sammelhefter 70 Druckerzeugnisse 21 in Richtung des Pfeiles 5 zugeführt werden. Diese Druckerzeugnisse 21 sind beispielsweise Broschuren, Kataloge, Zeitschriften oder andere Papierprodukte. In der Schneidmaschine 1 werden die Druckerzeugnisse 21 mittels einer Transportvorrichtung 7 einer ersten Schneidstation A zugeführt. Mit einem Messer 2 wird das Druckerzeugnis 21 in dieser ersten Station A frontseitig geschnitten. Anschliessend wird das Druckerzeugnis mit der Transportvorrichtung 7 zu einer zweiten Schneidstation B weitertransportiert. In dieser werden mit zwei Messern 6, von denen hier lediglich das eine gezeigt ist, ein Fuss- und Kopfschnitt ausgeführt. Anschliessend wird das dreiseitig geschnittene Druckerzeugnis 21 wieder mit der Transportvorrichtung 7 zur Weiterbehandlung wegtransportiert. Die Transportvorrichtung 7 weist Oberbänder 8 und Unterbänder 9 auf, mit denen die Druckerzeugnisse 21 einzeln geführt gegen Rückenanschläge 40 bzw. 41 angelegt werden.Figure 2 shows a cutting machine with a known Saddle stitcher 70 printed products 21 in the direction of arrow 5 are fed. These printed products 21 are, for example Brochures, catalogs, magazines or other paper products. In the cutting machine 1, the printed products 21 are by means of a transport device 7 fed to a first cutting station A. With a knife 2, the printed product 21 is in this cut first station A on the front. Subsequently the printed product with the transport device 7 becomes a transported to the second cutting station B. Be in this with two knives 6, only one of which is shown here is a foot and head cut. Then will the three-sided cut printed product 21 again with the Transport device 7 transported away for further treatment. The transport device 7 has upper belts 8 and lower belts 9 with which the printed products 21 individually guided against Back stops 40 and 41 are created.

Zur Umstellung der Schneidmaschine zwischen den beiden Schneidstationen A, B sind folgende drei Arbeitsgänge vorgesehen. In einem ersten Arbeitsgang werden entsprechend lange Messer 6 eingebaut. Die Messer 6 für den Kopf- und Fussschnitt sind somit auswechselbar. Alternativ können diese beiden Messer 6 in Transportrichtung verstellt werden. In einem zweiten Arbeitsschritt wird die Transportrichtung 7 umgestellt. In einfacher Weise kann dies beispielsweise durch Austauschen unterschiedlich grosser Antriebsrollen 14 und 15 (Figur 6) für die Antriebsbänder erfolgen. In einem dritten Schritt wird ausschliesslich die Anschlagdistanz durch Verschieben der Anschläge 40 und 41 angepasst.For moving the cutting machine between the two cutting stations A, B are the following three operations. In In a first operation, correspondingly long knives 6 built-in. The knives 6 for the head and foot cut are thus replaceable. Alternatively, these two knives 6 in Transport direction can be adjusted. In a second step the transport direction 7 is changed. In simple This can be done differently, for example, by exchanging large drive rollers 14 and 15 (Figure 6) for the drive belts respectively. In a third step, only the stop distance by moving the stops 40 and 41 adjusted.

Die Messer 2 und 6 sind mit einem konstanten Hub vertikal aufund abbewegbar. Dazu sind diese Messer 2 und 6 an einem in Figur 3 schematisch gezeigten Joch 29 angebracht, das über eine Kurbel 67 mit einem Kurbelantrieb 61 verbunden ist. Die Figur 4 zeigt einen vertikalen Schnitt durch diesen Kurbelantrieb 61. Dieser weist eine Kurbelscheibe 64 mit einer Stirnzahnung 65 auf, die auf einer gestellfesten Achse 62 drehbar gelagert ist. Knives 2 and 6 are vertically open with a constant stroke movable up. For this purpose, these knives 2 and 6 are on one in FIG 3 schematically shown yoke 29 attached via a Crank 67 is connected to a crank drive 61. Figure 4 shows a vertical section through this crank drive 61. This has a crank disk 64 with end teeth 65 on, which is rotatably mounted on an axle 62 fixed to the frame.

Mit einem hier nicht gezeigten Motor wird die Kurbelscheibe 14 im Uhrzeigersinn gedreht. Mit der Kurbelscheibe 64 ist ein Zapfen 66 fest verbunden, der in eine Führung 68 der Kurbel 67 eingreift und diese mit einem Hub C vertikal auf- und abbewegt, wobei die Schneidbewegung der Messer 2, 6 beim dargestellten Ausführungsbeispiel abwärts erfolgt, jedoch auch von unten nach oben ausgeführt werden könnte. Dies hätte zur Folge, dass zumindest die Pressleisten auf die gegenüberliegende Seite der Förderebene 74 verlegt werden müssen. Diese Bewegung wird auf das Joch 69 und schliesslich auf die Messer 2 und 6 übertragen. Wie bereits erwähnt, sind die Messer 6 auswechselbar am Joch 69 befestigt. Bei der in Figur 3 gezeigten Schneidmaschine 1 sind die Messer 6' länger als die Messer 6 in Figur 2. Entsprechend ist in Figur 3 der Abstand zwischen den beiden Anschlägen 40 und 41 grösser als der entsprechende Abstand in Figur 2. In Figur 2 beträgt dieser Abstand beispielsweise 305 mm und in Figur 3 355 mm. Die Länge der Messer 6 und 6' ist selbstverständlich so bemessen, dass die entsprechenden Druckerzeugnisse 21 bzw. 21' ohne gegenseitig gestört zu werden, an Kopf und Fuss geschnitten werden können. Dem längeren Druckerzeugnis 21' entspricht das entsprechend längere Messer 6'. Denkbar ist auch eine Ausführung, bei welcher das Messer 6 bzw. 6' horizontal verschiebbar am Joch 69 befestigt ist. Die Messer 2 und 6 sowie 6' weisen jeweils eine Pressleiste und ein Messerelement 4 auf. Zu jedem Messerelement 4 ist am Maschinengestell 71 ein Gegenmesser 36 (Figur 6) bzw. 72 (Figur 2) vorgesehen. Bei der gezeigten Ausführung wird zuerst der Frontschnitt ausgeführt. Denkbar ist jedoch auch eine Ausführung, bei welcher zuerst die Kopf- und Fussschnitte und nachher in der zweiten Schneidstation der Frontschnitt ausgeführt wird. Möglich ist in jedem Fall auch ein Mittelschnitt, der sogenannte Doppelnutzen. With a motor, not shown here, the crank disk 14 rotated clockwise. With the crank disk 64 is a pin 66 firmly connected to the guide 68 of the crank 67 engages and moves them vertically up and down with a stroke C, the cutting movement of the knives 2, 6 in the illustrated Embodiment takes place downwards, but also from the bottom down could be run above. This would have the consequence that at least the pressure bars on the opposite side of the Funding level 74 must be relocated. This movement is on the yoke 69 and finally transferred to the knives 2 and 6. As already mentioned, the knives 6 are interchangeable on the yoke 69 attached. In the cutting machine 1 shown in FIG the knives 6 'longer than the knives 6 in Figure 2. Correspondingly 3 is the distance between the two stops 40 and 41 larger than the corresponding distance in Figure 2. In Figure 2, this distance is, for example, 305 mm and in FIG 3,355 mm. The length of the knives 6 and 6 'is self-evident dimensioned such that the corresponding printed products 21 or 21 'cut to the head and foot without being disturbed can be. Corresponds to the longer printed product 21 ' the correspondingly longer knife 6 '. It is also conceivable an embodiment in which the knife 6 or 6 'horizontally is slidably attached to the yoke 69. Knives 2 and 6 as well 6 'each have a pressure bar and a knife element 4. For each knife element 4 there is a counter knife on the machine frame 71 36 (Figure 6) or 72 (Figure 2) provided. In the shown The front cut is carried out first. However, an embodiment is also conceivable in which the Head and foot cuts and afterwards in the second cutting station the front cut is carried out. It is possible in any case also a middle cut, the so-called double benefit.

Der Antrieb der Bänder 8 und 9 der Transportvorrichtung 7 erfolgt über eine Kurbelschleife 52, die mit einem Zahnriemen mit Antriebsrädern 18 und 19 (Figur 6) der Bandantriebe 12 und 13 verbunden ist. Die Kurbelschleife 52 weist eine Zahnscheibe 54 auf, die eine stirnseitige Zahnung 55 besitzt und mit einem Lager gestellfest drehbar gelagert ist. Die Zahnscheibe 54 kämmt mit der Kurbelscheibe 64 und wird von dieser angetrieben. Wie die Figur 5 zeigt, weist die Zahnscheibe 54 eine lineare Führung 56 auf, in welcher eine Rolle 57 eines Rades 58 verschiebbar geführt ist. Das Rad 58 dreht auf einer gestellfesten Achse 60 und weist eine Zahnung 59 auf, die mit dem Zahnriemen 20 in Eingriff ist. Die Exzentrizität und der Kurbelradius der umlaufenden Kurbelscheibe 52 ist konstant. Diese Kurbelscheibe 52 beschleunigt und verzögert die beiden Bänder 8 und 9 in geeigneter Weise für den Weitertransport der Produkte 21 bzw. 21'. Der Zahnriemen 20 treibt die Wellen 16 und 17 über die in Figur 6 gezeigten Zahnscheiben 18 und 19 an. Zur Umstellung des Formatbereiches sind die Antriebsrollen 14 und 15 austauschbar. In Figur 3 sind die Rollen 14 und 15 kleiner als diejenigen in Figur 3. Entsprechend ist in Figur 3 der Transportweg grösser. Für den Transport der Druckerzeugnisse 21 ist der Antrieb 12 für das Oberband 8 von den Druckerzeugnissen 21 mit einem vorbestimmten festen Hub abhebbar. Dazu ist eine Hubvorrichtung 24 vorgesehen, die ein Parallelgestänge 25 aufweist. Betätigt wird dieses Parallelgestänge 25 mittels einer Kurvenscheibe 35, die gemäss Figur 6 auf der Welle 16 befestigt ist. Eine Kurvenrolle 34 ist an diese Kurvenscheibe 35 angelegt und betätigt einen Kurvenhebel 33, der über ein gestellfestes Lager 32 und einer Schubstange 31 mit dem Parallelgestänge 25 verbunden ist. Dieses Gestänge wird in den Richtungen des Doppelpfeils 30 hinund herbewegt und bewegt entsprechend in vertikaler Richtung über gestellfeste Gelenke 28 und 29 einen Träger 22, an dem das Oberband 8 gelagert ist. Das Oberband 8 wird kurz vor dem Auftreffen der Druckerzeugnisse 21 angehoben und dadurch wird zwangsläufig der Transport dieser Druckerzeugnisse 21 unterbrochen. Das Ausrichten der Druckerzeugnisse 21 an den Anschlägen 40 und 41 erfolgt in an sich bekannter Weise durch den Ueberhub der Transportvorrichtung 7.The belts 8 and 9 of the transport device 7 are driven via a crank loop 52, which with a toothed belt Drive wheels 18 and 19 (Figure 6) of the belt drives 12 and 13 connected is. The crank loop 52 has a toothed disk 54 on, which has an end toothing 55 and with a bearing is rotatably mounted on the frame. The toothed disk 54 meshes with the crank disk 64 and is driven by this. How 5 shows, the toothed disc 54 has a linear guide 56, in which a roller 57 of a wheel 58 is displaceable is led. The wheel 58 rotates on an axis fixed to the frame 60 and has a toothing 59, which with the toothed belt 20 in Intervention is. The eccentricity and the crank radius of the orbiting Crank disk 52 is constant. This crank disc 52 accelerates and decelerates the two belts 8 and 9 in a suitable manner Way for the further transport of the products 21 and 21 '. The toothed belt 20 drives the shafts 16 and 17 via the in figure 6 toothed disks 18 and 19 shown. For changing the format range the drive rollers 14 and 15 are interchangeable. In Figure 3, the rollers 14 and 15 are smaller than those in Figure 3. Accordingly, the transport route is larger in FIG. 3. The drive 12 is for the transport of the printed products 21 for the upper band 8 of the printed products 21 with a predetermined fixed stroke can be lifted off. There is a lifting device 24 for this purpose provided that has a parallel linkage 25. Is pressed this parallel linkage 25 by means of a cam 35, the 6 is attached to the shaft 16. A curve roll 34 is applied to this cam 35 and actuates one Cam lever 33, which has a fixed bearing 32 and one Push rod 31 is connected to the parallel linkage 25. This Linkage is thundering in the directions of double arrow 30 moves and moves accordingly in the vertical direction via frame-fixed joints 28 and 29 a support 22 on which the Upper band 8 is stored. The upper band 8 is just before the impact the printed matter 21 is raised and thereby the transport of these printed products 21 is inevitably interrupted. Alignment of the printed products 21 on the stops 40 and 41 takes place in a manner known per se through the overstroke the transport device 7.

Die Anschläge 40 und 41 sind einzeln verstellbar an einem Träger 42 befestigt und können vertikal auf- und abbewegt werden. Der entsprechende Hub erfolgt auch hier über ein Parallelgestänge 43, das zwei gestellfeste Gelenke 46 und eine Verbindungsstange 47 aufweist. Das Parallelgestänge 43 ist über zwei im Abstand zueinander angeordneten Gelenken 45 mit dem Träger 42 verbunden. Mit einem zweiarmigen Hebel 48 ist die Stange 47 in den Richtungen des Doppelpfeils 44 horizontal hin- und herbewegbar. Der zweiarmige Hebel 48 ist an einem gestellfesten Gelenk 49 gelagert und mit einer Stange 50 gelenkig mit dem Parallelgestänge 43 verbunden. Der zweiarmige Hebel 48 wird um das Gelenk 49 mittels einer Rolle 51 verschwenkt, die an einer Steuerkurve 73 (Figur 3) anliegt. Die drehende Kurbelschleife 52 verschwenkt somit mit einem bestimmten Hub den zweiarmigen Hebel 48 und übt damit auf die beiden Anschläge 40 und 41 einen entsprechenden vertikalen Hub aus. In den Figuren 2 und 3 sind die Anschläge 40 und 41 in der oberen Position gezeigt, in welcher die Druckerzeugnisse 21 bzw. 21' an diesen Anschlägen 40, 41 anliegen. Für den Weitertransport werden diese Anschläge 40 und 41 nach unten bewegt. Zur Ausübung dieser Hubbewegung sind an sich auch andere Antriebe möglich. Wesentlich sind die horizontale Verschiebbarkeit der Anschläge 40 und 41 zur Veränderungen des Abstandes und die Aenderung des Schneidbereiches. The stops 40 and 41 are individually adjustable on a support 42 attached and can be moved up and down vertically. The corresponding stroke also takes place here via a parallel linkage 43, the two frame-fixed joints 46 and a connecting rod 47 has. The parallel linkage 43 is over two articulated joints 45 with the support 42 connected. With a two-armed lever 48, the rod 47 horizontally reciprocable in the directions of the double arrow 44. The two-armed lever 48 is fixed to a frame Joint 49 mounted and articulated with a rod 50 with the Parallel linkage 43 connected. The two-armed lever 48 is around the joint 49 is pivoted by means of a roller 51, which on a Control curve 73 (Figure 3) is present. The rotating crank loop 52 thus pivots the two-armed with a certain stroke Lever 48 and thus exercises one on the two stops 40 and 41 corresponding vertical stroke. In Figures 2 and 3 are the stops 40 and 41 are shown in the upper position, in which the printed products 21 and 21 'at these stops 40, 41 concerns. These stops become 40 for further transport and 41 moved down. To exercise this stroke motion are other drives are also possible. The horizontal ones are essential Movability of the stops 40 and 41 for changes of the distance and the change of the cutting area.

Zum Umstellen von einem auf den anderen Formatbereich wird somit die Anschlagdistanz der beiden Anschläge 40 und 41 angepasst. Ferner werden die Antriebsrollen 14 und 25 für den Transport der Druckerzeugnisse 21 bzw. 21' ausgetauscht. Zudem werden die entsprechend langen Messer 6 bzw. 6' eingebaut. Die anderen oben erwähnten Funktionen müssen nicht verändert werden. Dazu gehört insbesondere der Hub der Messer 6 bzw. 6', der Umlauf der Kurbelschleife 52, der Hub des Oberbandes 8 und der Hub der Anschläge 40 und 41. Der Messerhub ist somit unabhängig vom Formatbereich konstant. Der Messerhub und auch der Anschlaghub sind somit unabhängig vom Formatbereich konstant. Ebenfalls sind die Exzentrizität und der Kurbelradius der umlaufenden Kurbelschleife 52 konstant.To switch from one to the other format range is thus the stop distance of the two stops 40 and 41 adjusted. Furthermore, the drive rollers 14 and 25 for the Transport of the printed products 21 and 21 'exchanged. moreover the correspondingly long knives 6 and 6 'are installed. The other functions mentioned above need not be changed. This includes in particular the stroke of the knives 6 and 6 ', respectively Circulation of the crank loop 52, the stroke of the upper belt 8 and Stroke of the stops 40 and 41. The knife stroke is thus independent constant from the format range. The knife stroke and also the stop stroke are therefore constant regardless of the format range. Also the eccentricity and the crank radius of the rotating Crank loop 52 constant.

Im Interesse einer uneingeschränkten Umstellbarkeit der Schneidmaschine ist es sinnvoll, den Abstand der Messerträger 75 von dem Messer 2 für den Frontschnitt verstellen zu können.In the interest of unlimited convertibility of the Cutting machine it makes sense to set the distance between the knife carriers To be able to adjust 75 of the knife 2 for the front cut.
