Abstract

The invention relates to an apparatus for continuously trimming a feed of overlapping printed products. To save erection space in the printing room in in-line production, the cutting process is not carried out on a table-like cutting device, but the products are guided round the drum-shaped counterknife device, so that the exit of the cutting device is located on the same side as the entrance. The upper band line resting on the products ensures an improved pressure on the products during cutting as a result of the looping which occurs in this mode of operation. The two circular knives necessary for making a severing cut or cut-out are arranged offset on the circumference of the counterknife device. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device according to the preamble of patent claim 1.

Derartige Schneidvorrichtungen sind bezüglich der üblichen angewendeten Schneidtechnik z.B. in "Papierverarbeitung und Druck", Apr. 35/1979, S. 1054-1058 beschrieben. In der Graphischen Industrie richtet sich ihre Anwendung auf das Schneiden von Papierbahnen und auch auf das Schneiden von vereinzelt ausgelegten, durch vorheriges Querschneiden entstandener Druckprodukte, die im kontinuierlichen Prozeß gemäß der angewendeten Transportgeschwindigkeit entweder auf Lücke oder im sogenannten Schuppenstrom der Schneidvorrichtung zugeführt werden. Bei aus Falzapparaten erfolgender Auslage ist der Schuppenstrom die gängige Form, so daß der Schuppenstrom dann auch für die Weiterverarbeitungsprozesse maßgeblich ist.Such cutting devices are e.g. in "Paper Processing and Printing", Apr. 35/1979, pp. 1054-1058. In the graphics industry, their application is directed to the cutting of paper webs and also to the cutting of individually designed printed products which have been created by prior cross-cutting and which are fed to the cutting device in a continuous process according to the transport speed used either to a gap or in the so-called shingled stream. When delivery is made from folders, the shingled stream is the common form, so that the shingled stream is then also decisive for the further processing processes.

Im Gegensatz zum Schneiden von Papierbahnen, bei denen aufgrund des Bahnzugs keine zusätzlichen Maßnahmen zur Ausrichtung und Führung notwendig sind, erfordert das Schneiden vereinzelt ausgelegter Druckprodukte eine Transportvorrichtung, mit deren Hilfe die Produkte durch den Schneidspalt gefördert und gleichzeitig niedergehalten werden, damit die angreifenden Schneidkräfte kein Verrutschen bewirken.In contrast to the cutting of paper webs, where no additional measures for alignment and guidance are necessary due to the web tension, the cutting of individually designed printed products requires a transport device with which the products are conveyed through the cutting gap and at the same time held down so that the attacking cutting forces do not Cause slipping.

Die Anordnung nach der DE-OS 3022772 weist hierfür oberhalb und unterhalb der Transportbahn Transportbänder' auf, die das Schneidgut der Schneidvorrichtung zum Randbeschnitt zuführen. Eine ähnliche Schneidvorrichtung in Verbindung mit einer Bandleitung, die zum Transport des Schneidguts vorgesehen ist, zeigt das DE-GM 8401628.0, allerdings ist die Lage der Bandleitung auf die Durchführung eines Trennschnitts, also eines Schnitts, der mehr oder weniger innerhalb der Breite des Druckprodukts stattfindet, abgestellt.For this purpose, the arrangement according to DE-OS 3022772 has conveyor belts above and below the conveyor track, which feed the material to be cut to the cutting device for edge trimming. DE-GM 8401628.0 shows a similar cutting device in connection with a ribbon line, which is provided for transporting the material to be cut, but the position of the ribbon line is based on the implementation of a separating cut, that is to say a cut that takes place more or less within the width of the printed product , switched off.

Das zugehörige Messer ist als einstückiges Doppelmesser ausgebildet, so daß der zwischen den Schneidkanten liegende Streifen einen Span ungefähr von der Breite des Schneidkantenabstands ergibt.The associated knife is designed as a one-piece double knife, so that the strip lying between the cutting edges results in a chip approximately the width of the cutting edge distance.

Die Bandleitung ist gradlinig und dicht neben der Schnittlinie geführt, weil die Pressung des nachgiebigen Papiers im Schnittbereich eine große Rolle spielt.The ribbon cable is straight and close to the cutting line, because the compression of the flexible paper plays a major role in the cutting area.

Eine andere, im Hinblick auf die Streifenbreite des Herausschnitts variablere Vorrichtung zum Herausschneiden arbeitet mit versetzt angeordneten Kreismessern, wobei durch das zuerst kommende Kreismesser der erste Längsschnitt und durch das versetzt angeordnete Kreismesser der zweite Längsschnitt.erfolgt. Diese Art des Herausschneidens hat den Vorteil, daß die Rückwirkung des Spans, der bei schuppenförmig ausgelegten Druckprodukten relativ starr und widerstandsfähig sein kann, niedrig zu halten ist.Another device for cutting out, which is more variable with regard to the strip width of the cutout, works with offset circular knives, the first longitudinal cut coming through the first coming circular knife and the second longitudinal cut through the offset circular knife. This type of cutting out has the advantage that the reaction of the chip, which can be relatively rigid and resistant in the case of printed products in the form of scales, is to be kept low.

Die bekannten Schneidvorrichtungen sind aufgrund der zugehörigen Transportvorrichtungen durch die tischförmige Gestaltung geprägt.The known cutting devices are characterized by the table-shaped design due to the associated transport devices.

Die Transportbahn beschreibt eine ebene Fläche, weil das Schneidgut geradlinig zu- und abgeführt wird. Die Stellfläche solcher Schneidvorrichtungen ist groß, und außerdem führt ihr charakteristischer Aufbau dazu, daß die gesamte Verarbeitungsstrecke, auf der die Produktion In-line-mäßig von der Rolle weg über die Druckmaschine und weitere Aggregate bis zum gebrauchsfertigen Druckprodukt abläuft, relativ langgestreckt ist.The transport path describes a flat surface because the material to be cut is fed in and out in a straight line. The footprint of such cutting devices is large, and their characteristic structure also means that the entire processing line, on which the production runs in-line from the roll via the printing press and other units to the ready-to-use printed product, is relatively elongated.

Wenn die erwähnten Herausschnitte vorzunehmen sind, erwächst jedoch bei den tischförmig gestalteten Schneidvorrichtungen wegen der versetzten Kreismesseranordnung zusätzlicher Platzbedarf. Investitions-, Betriebs- und Wartungsaufwand nehmen damit nahezu proportional zu, zumal sich längere Verarbeitungswege insgesamt auch technisch gesehen schwieriger gestalten lassen.If the cutouts mentioned are to be made, however, additional space is required in the table-shaped cutting devices because of the offset circular knife arrangement. Investment, operating and maintenance expenses increase almost proportionally, especially since longer processing distances can also be made more difficult technically.

Das Herausschneiden betrifft wegen der damit zu erzielenden Produktionsvielseitigkeit eine Anwendung von zunehmender Bedeutung, denn es ermöglicht die übliche Formataufteilung, die sich am Druckzylinderumfang orientiert und meistens Querfalzen einbezieht, zu umgehen. Dadurch ergibt sich eine höhere Produktvielfalt im Hinblick auf kleine, handlichere Druckprodukte.The cutting out affects an application of increasing importance because of the production versatility that can be achieved with it, because it enables the customary format division, which is based on the circumference of the printing cylinder and mostly involves transverse folds, to be avoided. This results in a greater variety of products with regard to small, more manageable printed products.

Bei Aufteilung des Druckzylinderumfangs zum Beispiel in drei Produktlängen wird ein Abschnitt ausgelegt, dessen Länge dem Einfachen oder Mehrfachen des Druckzylinderumfangs entspricht. Dieser Abschnitt wird nachfolgend um 90° gegenüber der Transportrichtung gedreht, damit die ursprünglich quer zur Bahnabwicklungsrichtung liegenden Produktkanten oder Bildränder parallel zur Transportrichtung zu liegen kommen.If the circumference of the printing cylinder is divided into three product lengths, for example, a section is designed whose length corresponds to a single or multiple of the circumference of the printing cylinder. This section is subsequently rotated by 90 ° with respect to the transport direction so that the product edges or image edges originally lying transverse to the web development direction come to lie parallel to the transport direction.

Mit dieser Maßnahme können die einer Produktlänge zuordenbaren Einzelabschnitte mittels Längsschneiden gewonnen werden. Herausschnitte werden angewandt, wenn zwischen den angrenzenden Druckprodukten druckfreie Zonen oder Überfüllungen mit sich überschneidenden Druckbildern vorkommen, die zu entfernen sind..With this measure, the individual can be assigned to a product length sections are obtained by slitting. Cutouts are used when there are pressure-free zones or overfills with overlapping printed images that have to be removed between the adjacent print products.

Wegen des nachteiligen Platzbedarfs tischförmiger Schneidvorrichtungen zum kontinuierlichen Längsschneiden und des damit sich in die Länge streckenden Verarbeitungsweges bei In-line-Produktion besteht die Aufgabe der vorliegenden Erfindung darin, die Herausschnitt ermöglichende Schneidvorrichtung auf geringstmöglichen Raum zu beschränken und dabei auch günstige Verhältnisse für die zum Herausschneiden notwendige Anpressung der schuppenstromförmig ausliegenden Druckprodukte zu schaffen.Because of the disadvantageous space requirement of table-shaped cutting devices for continuous longitudinal cutting and the lengthening processing path in in-line production, the object of the present invention is to limit the cutting device which enables cutting out to the smallest possible space and at the same time also favorable conditions for cutting out to create the necessary contact pressure of the printed products in the form of a stream.

Die Merkmale des Kennzeichenteiles des Anspruches 1 beinhalten, daß mit der Schneidvorrichtung in einem Arbeitsgang der Schuppenstrom gleichzeitig geschnitten und gewendet wird.Indem der Gegenmesservorrichtung zusätzlich die Rolle eines Überführungszylinders zufällt, tritt der Schuppenstrom mit den beschnittenen Abschnitten in Gegenrichtung zur Zuführrichtung aus, und der Ausgang der Schneidvorrichtung liegt somit auf der Seite des Eingangs.The features of the characterizing part of claim 1 include that with the cutting device the scale stream is cut and turned simultaneously in one operation. In addition, the counter knife device also has the role of a transfer cylinder, the scale stream exits with the trimmed sections in the opposite direction to the feed direction, and the exit the cutting device is thus on the side of the entrance.

Während im Normalfall bei tischförmiger Anordnung der Schneidvorrichtung jedes versetzte Kreismesser auch je ein Gegenmesser erfordert, kommt die erfindungsgemäße Schneidvorrichtung bei zwei versetzt angeordneten Kreismessern mit nur einer Gegenmesservorrichtung aus.While in the case of a table-shaped arrangement of the cutting device, each offset circular knife also normally requires a counter knife, the cutting device according to the invention manages with only one counter knife device in the case of two offset circular knives.

Ebenmäßiger Kontakt der Druckprodukte mit. der Unterlage beim Transport und beim Schneiden wird dadurch gewährleistet, daß die Bänder der unteren Bandleitung in die die Unterlage bildende Mantelfläche der Gegenmesservorrichtung nahezu bündig eingelassen sind.Even contact of the printed products with. the base during transport and cutting is ensured by the fact that the strips of the lower ribbon line are embedded almost flush in the lateral surface of the counter knife device forming the base.

Die auf den Druckprodukten aufliegende obere Bandleitung ergibt durch die im Schneidbereich vorliegende Umschlingung eine zum Mittelpunkt der trommelförmigen Gegenmesservorrichtung gerichtete resultierende Anpressung, was sich als wesentliche Verbesserung gegenüber der bei gradlinig geführten Bändern ausgeübten Anpressung darstellt.The upper ribbon line resting on the printed products, due to the looping present in the cutting area, results in a resulting pressure directed towards the center of the drum-shaped counter knife device, which is a significant improvement over the pressure exerted in the case of straight ribbons.

Die Herumführung der Druckprodukte um die Gegenmesservorrichtung schafft auch einen gewissen Formschlußeffekt.Moving the printed products around the counter knife device also creates a certain positive locking effect.

Beides, sowohl der Formschlußeffekt als auch die erhöhte Anpressung kommen der Lagestabilität der Druckprodukte und damit der Schnittqualität zugute.Both the positive locking effect and the increased contact pressure benefit the positional stability of the printed products and thus the cut quality.

Eine vorteilhafte Weiterbildung betrifft die Veränderung der Schnittabstände bzw. der Breite des beim Herausschneiden anfallenden Spans mittels verschieden breiter Zwischenringe, die auf der Welle der Gegenmesservorrichtung sitzen.An advantageous further development relates to the change in the cutting distances or the width of the chip produced when cutting out by means of intermediate rings of different widths which are seated on the shaft of the counter knife device.

Zur Erzielung weitestgehender Schlupffreiheit der Druckprodukte zwischen der unteren und oberen Bandleitung ist ein geringer Überstand der Bänder der unteren und/oder oberen Bandleitung über die Oberfläche der Gegenmesservorrichtung und/oder der Antriebs- und Spannkörper für die Kreismesser vorgesehen.In order to achieve the greatest possible freedom from slippage of the printed products between the lower and upper ribbon line, a slight protrusion of the ribbons of the lower and / or upper ribbon line over the surface of the counter knife device and / or the drive and tensioning body for the circular knife is provided.

Die erforderliche'Synchronisation des Ablaufs der unteren und oberen Bandleitung mit der rotativen Bewegung der Kreismesser und der Gegenmesservorrichtung wird durch die Verwendung von Zahnriemen für die Bandleitungen einerseits und Zahnriemenscheiben in Verbindung mit den Kreismessern und der Gegenmesservorrichtung andererseits erzielt.The required synchronization of the sequence of the lower and upper band lines with the rotary movement of the circular knives and the counter knife device is achieved by using toothed belts for the band lines on the one hand and toothed belt pulleys in connection with the circular knives and the counter knife device on the other hand.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing, an embodiment of the invention is shown.

  • Fig. 2: Schematisierte Seitenansicht der Gegenmesservorrichtung und der Kreismesser, geklappt gemäß Ansicht X, Bänder geschnitten.
Show it:
  • Fig. 1: Schematic front view of the cutting device.
  • F ig. 2: Schematic side view of the counter knife device and the circular knife, folded according to view X, strips cut.

Das Zuführband 10 übernimmt den Antransport der in Schuppenform ausliegenden Druckprodukte als Abschnitte PB zur Schneidvorrichtung. Die Abmessung der sichtbaren seitlichen Kante eines Abschnitts P B ergibt sich aus der Breite der.gefalzten oder ungefalzten Bahnstränge; die Abmessung des Abschnitts PBquer zum Zuführband beträgt ungefähr die mehrere Produktlängen umfassende Breite B.The feed belt 10 takes over the transport of the printed products in the form of scales as sections P B to the cutting device. The dimension of the visible lateral edge of a section P B results from the width of the folded or unfolded web strands; the dimension of the section P B transversely to the feed belt is approximately the width B comprising several product lengths.

Die Schneidvorrichtung besteht aus für die Bandleitungen eingerichteten Umlenkwalzen 6,7,8,9, einer Umlenktrommel 3 und dem Kernstück, der Gegenmesservorrichtung 1 und den Kreismessern 2.The cutting device consists of deflection rollers 6, 7, 8, 9, set up for the strip lines, a deflection drum 3 and the core piece, the counter knife device 1 and the circular knives 2.

Die Schleife der unteren Bandleitung 4 schließt die Umlenkwalzen 6,9 und die Gegenmesservorrichtung 1 ein; die Schleife der oberen Bandleitung 5 verläuft über die Umlenkwalzen 7,8, die Umlenktrommel 3 und die Kreismesser 2. Es versteht sich von selbst, daß die Abrollung in der einen Schleife gegensinnig zu der Abrollung in der anderen Schleife verläuft.The loop of the lower band line 4 includes the deflecting rollers 6, 9 and the counter knife device 1; the loop of the upper ribbon line 5 runs over the deflection rollers 7, 8, the deflection drum 3 and the circular knife 2. It goes without saying that the unwinding in one loop runs in the opposite direction to the unwinding in the other loop.

Die Transportstrecke der Druckprodukte innerhalb der Schneidvorrichtung erstreckt sich vom Eingang E über die Umlenktrommel 3 und Gegenmesservorrichtung 1 mit den angestellten Kreismessern 1 zum Ausgang A. Üblicherweise sind Eingang E und Ausgang A als Einzieh- bzw. Austragsspalt zwischen der unteren und oberen Bandleitung 4,5 gebildet.The transport path of the printed products within the cutting device extends from the input E via the deflection drum 3 and the counter knife device 1 with the circular knives 1 set to the output A. Typically, input E and output A are a pull-in or discharge gap between the lower and upper ribbon lines 4, 5 educated.

Anschließend an den Ausgang A ist das Transportband 11 zum Abtransport der beschnittenen Produkte Pb angeordnet. Der vorfindbare Höhenunterschied H zwischen dem Zuführband 10 und dem Transportband 11 geht innerhalb der Schneidvorrichtung auf die Anordnung der in etwa oberhalb der Gegenmesservorrichtung 1 befindlichen Umlenktrommel 3 zurück. Hiermit verbunden vollzieht sich für die untere und obere Bandleitung 4,5 ein Krümmungswechsel, zudem wird eine größere Umschlingung der Bandleitung und damit der Druckprodukte im Bereich der Gegenmesservorrichtung 1 erzielt.Following the exit A, the conveyor belt 11 is arranged for the removal of the trimmed products P b . The difference in height H that can be found between the feed belt 10 and the conveyor belt 11 is due to the arrangement of the deflection drum 3 located approximately above the counter knife device 1 within the cutting device. In connection with this, a change of curvature takes place for the lower and upper ribbon lines 4, 5, and a larger wrap around the ribbon line and thus the printed products is achieved in the area of the counter knife device 1.

Der Durchmesser der Umlenktrommel 3 ist so gewählt, daß die Druckprodukte während ihrer Anlage an sie nicht knickbelastet sind, jedoch durch die vorgegebene Wölbung ihre Lage im Schuppenstrom stabilisiert wird.The diameter of the deflection drum 3 is selected so that the printed products are not subject to buckling during their contact with them, but their position in the scale flow is stabilized by the predetermined curvature.

Der Durchmesser der Gegenmesservorrichtung 1 muß so groß sein, daß sich ein geeigneter Abstand der zueinander versetzten Kreismesser 2 erreichen läßt und daß auch die Zugänglichkeit der Kreismesser 2 ge- währleistet ist. Weiterhin richtet sich der Durchmesser der Gegenmesservorrichtung 1 nach der Größe der einzusetzenden Nutenringe 1/1. Wie ersichtlich, läuft die obere Bandleitung 5 auf einem Teilkreis des Antriebs- und Spannkörpers 2/1 ab, der kleiner als der der-Schneidkante des Kreismessers 2 zurechenbare Teilkreis ist.The diameter of the counter-blade apparatus 1 must be such that a suitable spacing of the staggered blade 2 can be achieved and that the accessibility of the circular blade 2 g e - is ensured. Furthermore, the diameter of the counter knife device 1 depends on the size of the grooved rings 1/1 to be used. As can be seen, the upper ribbon line 5 runs on a pitch circle of the drive and tensioning body 2/1, which is smaller than the pitch circle attributable to the cutting edge of the circular knife 2.

Umlenkwalzen 6,7,8,9, Umlenktrommel 3 und Gegenmesservorrichtung 1 sind als Drehkörper auf Wellen gelagert, die sich zwischen nicht eingezeichneten Gestellwändenerstrecken. Gleichermaßen ortsfest gelagert sind die Stangen-2/3, auf denen die Halterungen 2/2 für die Kreismesser 2 klemm- und schwenkbar befestigt sind. Genaue-Justierung der Kreismesser 2 gegenüber der Gegenmesservorrichtung 1 bezüglich der Einstechtiefe ermöglicht der Verstelltrieb 2/4..Deflection rollers 6, 7, 8, 9, deflection drum 3 and counter knife device 1 are mounted as rotating bodies on shafts which extend between frame walls (not shown). The rods 2/3, on which the brackets 2/2 for the circular knives 2 are fastened in a clampable and pivotable manner, are equally fixedly mounted. The adjustment drive 2/4 enables precise adjustment of the circular knife 2 with respect to the counter knife device 1 with respect to the penetration depth.

Der Antrieb der unteren und oberen Bandleitung 4/5 erfolgt über die ausgangsseitigen Umlenkwalzen 8,9. Bedingt durch Seilreibung bzw. durch die Formschlüssigkeit beim Zahnriementrieb findet eine Antriebsübertragung auch auf die anderen, in die Schleifen der unteren und oberen Bandleitung 4,5 einbezogenen Drehkörper statt. Spannelemente, die auf die Bänder bzw. Riemen der unteren und oberen Bandleitung eingreifen, sind in bekannter Weise angeordnet.The lower and upper ribbon cables 4/5 are driven via the output-side deflection rollers 8.9. Due to the friction of the rope or the positive locking of the toothed belt drive, a drive transmission also takes place to the other rotating bodies involved in the loops of the lower and upper ribbon cables 4, 5. Tensioning elements which engage the belts or belts of the lower and upper belt line are arranged in a known manner.

Vom Ausgang A gelangen die Druckprodukte beschnitten als quer zur Transportrichtung liegende Einzelabschnitte Pb auf das Abtransportband 11. Die Abmessung der sichtbaren seitlichen Kante eines Einzelabschnitts Pb ergibt sich wiederum aus der Breite der gefalzten oder ungefalzten Bahnstränge; die Abmessung der Einzelabschnitte Pbquer zum Abtransportband 11 gehorcht der eingestellten Schnittbreite. Der mehrfache Herausschnitt führt zu einer entsprechenden Anzahl nebeneinander liegender, gebrauchsfertig beschnittener Druckprodukte Pb, die sich zum Beispiel unmittelbar anschließend stapeln lassen.From the exit A, the printed products arrive at the removal belt 11, trimmed as individual sections P b lying transversely to the transport direction. The dimension of the visible lateral edge of an individual section P b again results from the width of the folded or unfolded web strands; the dimension of the individual sections P b transversely to the conveyor belt 11 obeys the set cutting width. The multiple cut-out leads to a corresponding number of juxtaposed, ready-to-use cut printed products P b , which can be stacked immediately afterwards, for example.

Anfallende Späne vom Herausschneiden werden in bekannter, hier nicht aufgezeigter Weise kontinuierlichentfernt.Shavings from cutting out are continuously removed in a known manner, not shown here.

Fig. 2 zeigt die Ansicht X der Schneidvorrichtung in Bezug auf die hauptsächlichen zur Anordnung der Kreismesser 2 und der Gegenmesservorrichtung 1 gehörenden Teile.2 shows the view X of the cutting device in relation to the main parts belonging to the arrangement of the circular knives 2 and the counter knife device 1.

Die trommelförmige Gegenmesservorrichtung besteht im wesentlichen aus aneinandergereihten Ringen, die klemm- und verschiebbar auf die Welle 1/3 aufgebracht sind. An die Zwischenringe 1/2, die in Anpassung an die anzuwendenden Schnittabstände in verschiedener Breite ausgeführt sein können, sind beidseitig Nutenringe 1/1 angeflanscht. Der Abstand der Nutenringe 1/1, die in Richtung der Nut Vorsprünge tragen, so daß ein Nutenring 1/1 mit dem gegenüberliegenden Nutenring 1/1 ein schwalbenschwanzförmiges Profil ergibt, bestimmt die Breite des Herausschnitts bzw. des Spans. Den seitlichen Abschluß des aus Ringen bestehenden Aufbaues der Gegenmesservorrichtung 1 bilden die Deckringe 1/5.The drum-shaped counter-knife device consists essentially of rows of rings which are applied to the shaft 1/3 so that they can be clamped and moved. Grooved rings 1/1 are flanged on both sides of the intermediate rings 1/2, which can be designed in different widths to match the cutting distances to be used. The distance between the groove rings 1/1, which carry projections in the direction of the groove, so that a groove ring 1/1 with the opposite groove ring 1/1 results in a dovetail-shaped profile determines the width of the cutout or the chip. The cover rings 1/5 form the lateral end of the structure of the counter knife device 1 consisting of rings.

Zur Ausübung optimaler Anpressung auf die zu schneidenden Druckprodukte vor allem unmittelbar in Höhe der Schnittlinie bildet der Nutenring 1/1 mit einem Absatz des Zwischenrings 1/2 die zur Führung eines Bands der unteren Bandleitung vorzugebende Führungsnut 1/4. Damit nimmt die Bandleitung den geringstmöglichen Parallelabstand zur Schnittlinie ein.In order to exert optimal pressure on the printed products to be cut, especially directly at the cutting line, the groove ring 1/1 with a shoulder of the intermediate ring 1/2 forms the guide groove 1/4 to be specified for guiding a band of the lower band line. This means that the ribbon cable takes the smallest possible parallel distance to the cutting line.

Bei entsprechend gewähltem Überstand des Bands über die ablaufende Außenfläche der Gegenmesservorrichtung und/oder die Außenfläche des Antriebs-und Spannkörpers lassen sich Anpressung und Transport der Druckprodukte aufgrund der gummielastischen Eigenschaft der Bänder und der Reibwertbeeinflussung noch verbessern.If the tape protrudes accordingly over the running outer surface of the counter-knife device and / or the outer surface of the drive and tensioning body, the pressure and transport of the printed products can be improved further on account of the rubber-elastic property of the belts and the influence on the coefficient of friction.

Erforderlichenfalls kann die für den Bandlauf vorgesehene Führungsnut auch mittels zwischengeflanschter Zahnriemenscheiben gewonnen werden, um den Antrieb formschlüssig zu gestalten. Die Übersetzung der Zahnriemenscheiben wird dabei so ausgewählt, daß die bezweckte Voreilung zustande kommt.If necessary, the guide groove provided for the belt run can also be obtained by means of flanged toothed belt pulleys in order to design the drive with a positive fit. The translation of the toothed belt pulleys is selected so that the intended advance is achieved.

Teilweise ist von nun an zusätzliche Apostrophierung zur besseren Unterscheidung der oben und der versetzt untenliegenden Anordnung der Kreismesser eingeführt.In some cases, additional apostrophes have been introduced to better distinguish between the top and bottom staggered arrangement of the circular knives.

Die Kreismesser 2 sind an Antriebs- und Spannkörpern 2/1 befestigt, die auf den Enden von schwenk- und klemmbaren Halterungen 2/2 gelagert sind. Die Halterungen 2/2' der Kreismesser 2', die die eine Seite des Herausschnitts tätigen und deshalb gleiche Orientierung zeigen, sind über eine obere Stange 2/3' verbunden; die Halterungen 2/2" für die versetzt angeordneten Kreismesser 2", die die andere Seite des Herausschnitts tätigen, sind entsprechend auf einer unteren Stange 2/3" angeordnet. Die obere und die untere Stangen 2/3', 2/3" ertrecken sich wiederum zwischen den nicht aufgezeigten Gestellwänden.The circular knives 2 are fastened to drive and clamping bodies 2/1, which are mounted on the ends of pivotable and clampable brackets 2/2. The brackets 2/2 'of the circular knife 2', which make one side of the cutout and therefore show the same orientation, are connected via an upper rod 2/3 '; the holders 2/2 "for the offset circular knives 2", which make the other side of the cutout, are correspondingly arranged on a lower rod 2/3 ". The upper and lower rods 2/3 ', 2/3" extend in turn between the frame walls not shown.

Jedes Kreismesser 2 ist somit einzelaufgehängt und läßt sich individuell sowohl seitlich in Anpassung an die Schnittabstände als auch bezüglich der Einstechtiefe in die durch die Nutenringe 1/1 gebildete.Schneidnut einstellen. Auf diese Weise ergibt sich auch eine praktische Handhabung für das Nachstellen im Verschleißfall. Die genaue: Justierung der Einstechtiefe wird mit dem in Fig. 1 gezeigten Verstelltrieb 2/4 vorgenommen. Bedingt durch die Einzelaufhängung der Kreismesser benötigt jedes Kreismesser 2 Einzelantrieb. Zu diesem Zweck greift jeweils ein Band in einer in den Antriebs- und Spannkörper 2/1 integrierte Zahnriemenscheibe.Each circular knife 2 is thus individually suspended and can be individually adjusted both laterally in accordance with the cutting distances and with respect to the penetration depth in the cutting groove formed by the grooved rings 1/1. This also results in practical handling for readjustment in the event of wear. The exact one: adjustment the penetration depth is carried out with the adjustment drive 2/4 shown in FIG. 1. Due to the individual suspension of the circular knives, each circular knife requires 2 individual drives. For this purpose, a band engages in a toothed belt pulley integrated in the drive and tensioning body 2/1.

Nachdem die Bänder jeweils beidseitig eines Herausschnitts verlaufen, also diesen förmlich zwischen sich nehmen und die Zahl der Bänder innerhalb eines Bandsatzes der unteren und der oberen Bandleitung 4,5 jeweils um 1 höher als die Zahl der Herausschnitte liegt, ist oben und unten je einer der außenliegenden Antriebs- und Spannkörper 2/1 ohne Kreismesser 2 und nur zur Führung eines Bands angeordnet.After the tapes run on both sides of a cut-out, so take it formally between them and the number of tapes within a tape set of the lower and the upper tape line 4.5 is 1 higher than the number of cut-outs, one is at the top and one at the bottom external drive and tensioning body 2/1 without circular knife 2 and only arranged for guiding a band.

Fig. 2 zeigt nochmals deutlich, daß die mit dem Schuppenstrom in Berührung kommenden, sich abwälzenden Außenflächen der Gegenmesservorrichtung 1 und der Antriebs- und Spannkörper 2/1 mit einer Umfangsgeschwindigkeit laufen, die gleich der Geschwindigkeit der Außenfaser der Bänder der unteren und oberen Bandleitung 4,5 ist. Die Schneidkanten laufen wegen ihres größeren Durchmessers schneller.Fig. 2 shows again clearly that the rolling outer surfaces of the counter knife device 1 and the drive and tensioning bodies 2/1 coming into contact with the scale flow run at a peripheral speed which is equal to the speed of the outer fiber of the bands of the lower and upper band lines 4 , 5 is. The cutting edges run faster because of their larger diameter.

Das vorliegende Ausführungsbeispiel ergibt systematisch mit 4 Paaren von Kreismessern 2 mit jeweils einem Satz Kreismesser auf der oberenThe present embodiment results systematically with 4 pairs of circular knives 2, each with a set of circular knives on the upper one

bzw. unteren Stange 2/3', 2/3" zur Tätigung der einen bzw. der anderen Seite der Herausschnitte, 4 Paaren von Nutenringen 1/1, 5 Paaren von Antriebs-und Spannkörpern 2/1 und fünf Zwischenringen 1/2,vier Herausschnitte. Gemäß dieser Systematik lassen sich beliebige Varianten der SChneidvorrichtung in Bezug auf die.Zahl der zu tätigenden Herausschnitte und anhand der Zwischenringe in Bezug auf die Schnittabstände ableiten. Bei Verzicht einer, z.B. der oberen oder unteren Anordnung von Kreismessern 2 ist statt Herausschnitt auch sog. Durch-oder Trennschnitt möglich. Dabei fällt selbstverständlich kein Span an.
