Abstract

A bookbinding machine for rounding the backs of book blocks, having a conveying device which clamps the book block and having a back-rounding device consisting of rounding rollers which, when the book block has been released by the conveying device, act on both sides of the book block by a defined rotary movement and by pressure, is characterised in terms of a substantial improvement in performance in that rounding rollers (7, 8) are provided in a conveying device having book block clamps (2) which can be moved continuously in a closed-loop circulating path, which rounding rollers can be driven synchronously with the book block clamps (2) along a path of movement, in which case the rounding rollers (7, 8) can be moved back and forth through recesses (3a, 4a) in clamping jaws (3, 4) of the book block clamps (2) for carrying out the rounding operation at the sides of the book block (1). Furthermore, the rounding rollers (7, 8) can be moved vertically in the recesses (3a, 4a) of the clamping jaws (3, 4) and the vertical movement is superimposed on the rotary movement of the rounding rollers (7, 8) in such a way that the vertical movement of the book block (1) generated as a result of the rotary movement is compensated, the outlying sheets or printed sheets of said book block preferably being held at a constant level. <IMAGE>

Description

Die Erfindung betrifft eine Buchbindemaschine zum Rückenrunden von Buchblocks mit einer den Buchblock einspannenden Fördereinrichtung und mit einer Rückenrundeeinrichtung, bestehend aus Rundewalzen, die nach Freigabe des Buchblocks durch die Fördereinrichtung auf beide Seiten des Buchblocks durch eine definierte Drehbewegung sowie durch Druck einwirken.The invention relates to a bookbinding machine for back rounding of book blocks with a conveying device which clamps the book block and with a back rounding device consisting of round rollers which act on both sides of the book block by a defined rotary movement and by pressure after the book block has been released by the conveying device.

Das Rückenrunden von Buchblocks, ein Arbeitsgang in der Buchherstellung, durch den der Buchblock die gewünschte gerundete Form des Rückens und gleichzeitig des Vorderschnitts erhält, wird in heutigen Buchblockbearbeitungsmaschinen überwiegend nach dem Walzenrundeprinzip durchgeführt. Dabei erfolgt eine fließende Relativverschiebung der einzelnen Blätter bzw. Druckbogen durch gleichzeitiges Abwälzen geriffelter Rundewalzen an den Buchblockseiten über einen definierten Drehwinkel sowie unter Druckanwendung, wobei die Blätter bzw. Druckbogen beim Durchlauf des Buchblocks durch die Rundewalzen zur Buchblockmitte hin zunehmend vorgeschoben werden.The back rounding of book blocks, a work step in book production, through which the book block receives the desired rounded shape of the spine and at the same time the pre-cut, is carried out in today's book block processing machines predominantly according to the roller round principle. A smooth relative displacement of the individual sheets or printed sheets takes place by simultaneously rolling corrugated round rollers on the sides of the book block over a defined angle of rotation and under pressure, the sheets or printed sheets being increasingly advanced towards the center of the book block as the book block passes through the round rollers.

Aus der DE-OS 15 36 507 ist eine Buchbindemaschine zum Runden und gleichzeitig zum Formen von Buchblockrücken bekannt mit einer Fördereinrichtung, die die Buchblocks intermittierend in Längsrichtung durch Bearbeitungsstationen befördert, indem sich Gruppen von einander mit veränderbarem Abstand gegenüberliegenden Klemmbacken gegen die Seiten des Buchblocks legen, um diese zu erfassen und sie in die Rundewalzen bzw. in die Formstation zu transportieren. In der Rundestation gelangt der Buchblock in den Wirkbereich zweier geriffelter Rundewalzen, die auf den Buchblock einwirken und den Rücken durch Verschieben der Blätter bzw. Druckbogen formen, nachdem sich zuvor die Klemmbacken von den Buchblockseiten gelöst haben.From DE-OS 15 36 507 a bookbinding machine for rounding and at the same time for forming book block spines is known with a conveyor device, which intermittently conveys the book blocks in the longitudinal direction through processing stations, in that groups of mutually opposite clamping jaws lie against the sides of the book block in order to grasp them and to transport them into the round rollers or into the forming station. In the round station, the book block comes into the working area of two corrugated round rollers, which act on the book block and form the spine by moving the sheets or printed sheets after the clamping jaws have detached from the pages of the book block.

Um den Wirkungsgrad dieser Buchbindemaschine zum Runden und Formen von Buchblocks zu erhöhen, ist vorgesehen, für einen erheblichen Prozentsatz der beweglichen Teile der Fördereinrichtung einen leichten Werkstoff zu verwenden, wodurch die Lineargeschwindigkeit, mit der die Buchblocks von Station zu Station befördert werden, erhöht wird.In order to increase the efficiency of this book binding machine for rounding and shaping book blocks, it is envisaged to use a light material for a considerable percentage of the moving parts of the conveyor device, which increases the linear speed with which the book blocks are transported from station to station.

Infolge der intermittierenden Arbeitsweise kann die Runde- und Formmaschine nach der DE-OS 15 36 507 nur in einem begrenzten Leistungsbereich zur Anwendung gelangen.As a result of the intermittent mode of operation, the rounding and forming machine according to DE-OS 15 36 507 can only be used in a limited performance range.

Die Aufgabe der Erfindung besteht darin, eine Buchbindemaschine zum Rückenrunden von Buchblocks der gattungsgemäßen Art zu schaffen, mit der sich eine wesentliche Steigerung der Arbeitsgeschwindigkeit erreichen läßt.The object of the invention is to provide a bookbinding machine for the back rounding of book blocks of the generic type, with which a substantial increase in the working speed can be achieved.

Ausgehend von einer Buchbindemaschine zum Rückenrunden von Buchblocks mit einer den Buchblock einspannenden Fördereinrichtung und mit einer Rückenrundeeinrichtung, bestehend aus Rundewalzen, die nach Freigabe der Buchblocks durch die Fördereinrichtung auf beide Seiten des Buchblocks durch eine definierte Drehbewegung sowie durch Druck einwirken, wird die Aufgabe der Erfindung gelöst durch eine Fördereinrichtung mit in einer geschlossenen Umlaufbahn kontinuierlich bewegbaren Buchblockklammern und durch Rundewalzen, die mit den Buchblockklammern längs einer Bewegungsbahn synchron antreibbar und durch Ausnehmungen in Klemmbacken der Buchblockklammern zum Ausführen des Rundevorgangs zu den Seiten des Buchblocks hin- und zurückbewegbar sind.Starting from a bookbinding machine for back rounding of book blocks with a conveying device that clamps the book block and with a back rounding device consisting of round rollers that act on both sides of the book block by means of a defined rotary movement and by pressure after the book blocks have been released by the conveying device, the object of the invention solved by a conveyor with book block clamps which can be moved continuously in a closed orbit and by round rollers which can be driven synchronously with the book block clamps along a movement path and by recesses in clamping jaws of the book block clamps for execution of the round process can be moved back and forth to the pages of the book block.

Mit der erfindungsgemäßen Buchbindemaschine wird erstmals ein Weg aufgezeigt, das Rückenrunden von Buchblocks in einem Buchblocktransportsystem mit in einer geschlossenen Umlaufbahn kontinuierlich bewegbaren Buchblockklammern durchzuführen. Bekanntlich wurden solche Buchblocktransportsysteme bisher ausschließlich für Buchbindemaschinen im Höchstleistungsbereich eingesetzt.With the book binding machine according to the invention, a way is shown for the first time of carrying out the back rounding of book blocks in a book block transport system with book block clamps which can be moved continuously in a closed orbit. As is known, such book block transport systems have hitherto been used exclusively for high-performance bookbinding machines.

Nach einem weiteren Merkmal der Erfindung sind die Rundewalzen in den Ausnehmungen der Klemmbacken vertikal verfahrbar und die Vertikalbewegung ist der Drehbewegung der Rundewalzen überlagert derart, daß die infolge der Drehbewegung erzeugte Vertikalbewegung des Buchblocks kompensiert wird, wobei vorzugsweise dessen außenliegenden Blätter bzw. Druckbogen auf konstantem Niveau gehalten werden. Das durch die Kompensationsbewegung bewirkte Halten des Buchblocks in der Klammer des Buchblocktransportsystems in einer definierten Position, ist für den nachfolgenden Arbeitsprozess von Bedeutung.According to a further feature of the invention, the round rollers can be moved vertically in the recesses of the clamping jaws and the vertical movement is superimposed on the rotary movement of the round rollers in such a way that the vertical movement of the book block which is produced as a result of the rotary movement is compensated for, the outer sheets or printed sheets preferably being at a constant level being held. The holding of the book block in the clamp of the book block transport system in a defined position caused by the compensation movement is important for the subsequent work process.

Eine weitere Steigerung der Arbeitsgeschwindigkeit läßt sich gemäß einem weiteren Merkmal der Erfindung dadurch erzielen, daß in der Buchbindemaschine wenigstens eine weitere Rückenrundeeinrichtung zum gleichzeitigen Rückenrunden von mehreren Buchblocks angeordnet ist.According to a further feature of the invention, a further increase in the working speed can be achieved in that at least one further back rounding device for simultaneous back rounding of several book blocks is arranged in the bookbinding machine.

Andere vorteilhafte Merkmale ergeben sich aus den verbleibenden Unteransprüchen.Other advantageous features emerge from the remaining subclaims.

Die Einrichtung zum Rückenrunden von Buchblocks 1 ist erfindungsgemäß einem Buchblocktransportsystem einer Buchbindemaschine zugeordnet mit einer Vielzahl von in gleichen gegeneitigen Abständen zueinander Liegenden Buchblockklammern 2, mit je einem Paar mit veränderbarem Abstand gegenüberliegenden Klemmbacken 3 und 4, die zum Aufbringen einer Haltekraft einen Anpreßdruck auf die Seiten eines mit dem Rücken nach unten weisenden Buchblocks 1 ausüben. Dabei ist die innere Klemmbacke 4 der Klammer 2 ortsfest an einem in Führungen 5 eines Maschinengestells laufenden, mit einer Transportkette antriebsmäßig verbundenen Tragrahmen 6 befestigt und die äußere Klemmbacke 3 zur inneren Klemmbacke 4 über nicht dargestellte Betätigungsmittel im Sinne eines Schließens und öffnens zur Aufnahme bzw. Freigabe eines Buchblocks 1 parallel verschiebbar. Die Klammern mit den eingespannt gehaltenen Buchblocks 1 sind längs einer geschlossenen Umlaufbahn von der um Umlenkkettenräder geführten Transportkette kontinuierlich angetrieben.The device for back rounding of book blocks 1 is, according to the invention, assigned to a book block transport system of a bookbinding machine with a plurality of book block clamps 2 lying at the same mutual distance from one another, each with a pair of clamping jaws 3 and 4 opposite one another with variable spacing, which exert a contact pressure on the pages for applying a holding force exercise one of the book blocks 1 with the back facing down. The inner jaw 4 of the clamp 2 is fixed in place on a support frame 6 which runs in guides 5 of a machine frame and is connected to a transport chain by a drive chain, and the outer jaw 3 to the inner jaw 4 via actuating means (not shown) in the sense of closing and opening for receiving or Release of a book block 1 can be moved in parallel. The clamps with the book blocks 1 held clamped are continuously driven along a closed orbit by the transport chain guided around deflection sprockets.

Die Einrichtung zum Rückenrunden von Buchblocks befindet sich im wesentlichen unterhalb des Buchblocktransportsystems und in einem geradlinig verlaufenden Streckenabschnitt und wird von einer Antriebsanordnung, deren nähere Beschreibung an anderer Stelle erfolgt, mit den kontinuierlich laufenden Klammern 2 längs der Bewegungsbahn über eine definierte Wegstrecke synchron vor- und danach unter Umkehrung ihrer Bewegungsrichtung in die Ausgangsposition zurückbewegt.The device for back rounding of book blocks is located essentially below the book block transport system and in a straight line section and is supported by a drive arrangement, the detailed description of which is given elsewhere the continuously running brackets 2 along the path of movement over a defined distance in a synchronous manner and then moved back to the starting position, reversing their direction of movement.

Beim Rückenrunden von Buchblocks nach dem Walzenrundeverfahren erfolgt bekanntlich eine fließende Relativverschiebung der einzelnen Blätter bzw. Druckbogen durch gleichzeitiges Abwälzen geriffelter Rundewalzen über einen definierten Drehwinkel sowie unter Druckanwendung, wobei die Blätter bzw. Druckbogen beim Durch lauf des Buchblocks durch die Rundewalzen zur Buchblockmitte hin zunehmend vorgeschoben werden und somit der Buchblock seine gewünschte gerundete Rückenform und Vorderschnittform erhält.When backing round book blocks using the roller rounding method, it is known that there is a flowing relative displacement of the individual sheets or printed sheets by simultaneously rolling corrugated round rolls over a defined angle of rotation and under pressure, the sheets or printed sheets being increasingly advanced toward the center of the book block as the book block runs through the round rolls and thus the book block gets its desired rounded back shape and front cut shape.

Um das Rückenrundeverfahren an einem Buchblock 1 innerhalb der Klammer 2 durchführen zu können, sind gemäß der Erfindung Ausnehmungen 3a, 4a in der inneren und äußeren Klemmbacke 3, 4 vorgesehen, durch die die Rundewalzen 7, 8 während ihres Synchronlaufs mit der Klammer 2 zu den Buchblockseiten hin- und zurückbewegbar sind. Diese in Querrichtung erfolgende Bewegung der beiden Rundewalzen muß zwangsläufig zeitlich derart auf die öffnungs- und Schließbewegung der Klemmbacken 3, 4 abgestimmt sein, daß der Buchblock 1 erst nach Übernahme durch die Rundewalzen 7, 8 von den Klemmbacken 3, 4 freigegeben wird, worauf unmittelbar der Rundevorgang einsetzt, indem sich die drehangetriebenen Rundewalzen 7, 8 an den Seiten des Buchblocks 1 abwälzen.In order to be able to carry out the back rounding process on a book block 1 within the clamp 2, according to the invention, recesses 3a, 4a are provided in the inner and outer clamping jaws 3, 4, through which the round rollers 7, 8 during their synchronous operation with the clamp 2 Book block pages are movable back and forth. This transverse movement of the two round rollers must inevitably be timed to the opening and closing movement of the clamping jaws 3, 4 in such a way that the book block 1 is only released by the clamping jaws 3, 4 after being taken over by the round rollers 7, 8, whereupon immediately the rounding process begins by rolling the rotary drives 7, 8 on the sides of the book block 1.

Wie besonders deutlich aus Figur 2 ersichtlich, werden die beiden Rundewalzen 7, 8 gleichzeitig mit ihrer Drehbewegung gemäß Pfeilrichtung in den Ausnehmungen 3a, 4a der Klemmbacken 3, 4 aus einer unteren Position in eine obere strichpunktiert dargestellte Position angehoben, wodurch die infolge Abwälzens der Rundewalzen 7, 8 an den Seiten des Buchblocks 1 auftretende nach unten gerichtete Vertikalbewegung des Buchblocks 1 kompensiert und somit die Falzkante am Rande des Buchblocks in der Klammer 2 auf konstantem Niveau gehalten wird.As can be seen particularly clearly from FIG. 2, the two round rollers 7, 8 are simultaneously raised with their rotary movement according to the direction of the arrow in the recesses 3a, 4a of the clamping jaws 3, 4 from a lower position to an upper position shown in broken lines, as a result of which the round rollers roll off 7, 8 on the sides of the book block 1 occurring downward vertical movement of the book block 1 is compensated and thus the fold edge on the edge of the book block in the bracket 2 is kept at a constant level.

Nach ausgeführtem Rundevorgang und Abschwenken kehren die Rundewalzen 7, 8 in ihre untere Ausgangsposition zurück.After the rounding process and swiveling, the rounding rollers 7, 8 return to their lower starting position.

Die längs der Bewegungsbahn der Klammern 2 vor- und zurück laufend angetriebene Einrichtung zum Rückenrunden von Buchblocks 1 weist einen Rahmen 10 auf, der sich aus einer Grundplatte 10a und einer Tragplatte 10b zusammensetzt, die auf Führungsstangen 17 der Grundplatte 10a in vertikaler Ebene verfahrbar ist.The device for back-rounding book blocks 1, which is driven back and forth along the path of movement of the clamps 2, has a frame 10 which is composed of a base plate 10a and a support plate 10b which can be moved in a vertical plane on guide rods 17 of the base plate 10a.

Von der höhenbeweglichen Tragplatte 10b werden beidseitig der Buchblockbewegungsebene in diametraler Anordnung um einen mittleren Drehpunkt schwenkbar gelagerte Schwenkhebelpaare 14, 15 aufgenommen, in denen die beiden Rundewalzen 7, 8 jeweils endseitig frei drehbar gelagert sind. Hierzu befinden sich auf der Tragplatte 10b Lagerböcke 11, 12 zur Aufnahme von Lagerwellen 13, die wiederum die Schwenkhebelpaare 14, 15 tragen.The vertically movable support plate 10b receives on both sides of the book block movement plane in a diametrical arrangement pivotally mounted pairs of pivot levers 14, 15, in which the two round rollers 7, 8 are each freely rotatably supported at the ends. For this purpose, there are bearing blocks 11, 12 on the support plate 10b for receiving bearing shafts 13, which in turn carry the pairs of swivel levers 14, 15.

Die Schwenkbewegung der Rundewalzen 7, 8, ausgeführt über die Schwenkhebelpaare 14, 15, zu den Buchblockseiten hin und zurück, geht von einem Arbeitszylinder 16 aus, an dessen Zylinder 16a das unter der inneren Klemmbacke 4 liegende Schwenkhebelpaar 15 und an dessen Kolbenstange 16b das unter der äußeren Klemmbacke 3 liegende Schwenkhebelpaar 14 angreift. Durch Beaufschlagen des Arbeitszylinders 16 werden die beiden Schwenkhebelpaare 14, 15 mit den Rundewalzen 7, 8 durch Ausfahren der Kolbenstange 16b um ihre mittigen Drehpunkte zu den Buchblockseiten hin verschwenkt. Das Abschwenken erfolgt durch Zurückziehen der Kolbenstange 16 bis hin zur Anlage der Schwenkhebelpaar 14, 15 an Anschläge 18.The pivoting movement of the round rollers 7, 8, carried out via the pivoting lever pairs 14, 15, back and forth to the book block pages, starts from a working cylinder 16, on the cylinder 16a of which the pivoting lever pair 15 lying under the inner clamping jaw 4 and on the piston rod 16b of which the outer jaw 3 engages lying pair of pivot levers 14. By acting on the working cylinder 16, the two pairs of pivot levers 14, 15 are pivoted with the round rollers 7, 8 by extending the piston rod 16b about their central pivot points toward the pages of the book block. The pivoting takes place by pulling back the piston rod 16 until the pair of pivot levers 14, 15 abut against stops 18.

Die Hubbewegung der beiden Rundewalzen 7, 8 in den Ausnehmungen 3a, 4a der Klemmbacken 3, 4 und die gleichzeitig ablaufende Drehbewegung der beiden Rundewalzen 7, 8 zum Ausführen des Rundevorgangs erfolgt in zeitlicher Abstimmung mit der Querbewegung zu den Buchblockseiten hin und mit der kontinuierlich laufenden Buchblockklammer 2 von einer gemeinsamen nicht weiter dargestellten Antriebsquelle ausgehend auf einen Antriebshebel 20, durch den Parallelhebelanordnungen 21, wiederum auf beiden Seiten der Buchblockbewegungsebene liegend sowie untereinander verbunden, betätigt werden. Die Parallelhebelanordnungen greifen jeweils an zwei voneinander entfernt liegenden Punkten der Tragplatte 10b an, um diese, geführt auf Stangen 17, zwischen einer unteren und oberen Endstellung zu verfahren.The lifting movement of the two round rollers 7, 8 in the recesses 3a, 4a of the clamping jaws 3, 4 and the simultaneous rotary movement of the two round rollers 7, 8 for executing the rounding process take place in time with the transverse movement towards the book block pages and with the continuously running one Book block clamp 2 starting from a common drive source, not shown on a drive lever 20, by means of the parallel lever arrangements 21, again lying on both sides of the book block movement plane and connected to one another. The parallel lever arrangements each engage at two points on the support plate 10b which are at a distance from one another in order to move it, guided on rods 17, between a lower and an upper end position.

Mit der Hubbewegung führen die beiden Rundewalzen 7, 8 eine definierte Drehbewegung zum Vollziehen des Rundevorgangs am Buchblock aus, indem ortsfeste Zahnstangen 22 und 22a Zahnritzel 23 auf den Lagerwellen 13 in Drehbewegung versetzen. Von dem Zahnritzel 23 aus erfolgt die Übertragung der Drehbewegung auf die Rundewalzen 7, 8 über einen Zahnriemen 29 zwischen einem Zahnrad 24 auf der Lagerwelle 13 und einem Zahnrad 25 auf einer im Schwenkhebelpaar 14, 15 gelagerten Zwischenwelle 26. Auf dieser befindet sich ein Zahnrad 27, das mit einem Zahnrad 28 auf der Achse der Rundewalzen 7, 8 in Eingriff steht.With the lifting movement, the two round rollers 7, 8 perform a defined rotary movement to complete the rounding process on the book block, in that stationary toothed racks 22 and 22a set toothed pinions 23 on the bearing shafts 13 in rotary movement. From the pinion 23, the rotary movement is transmitted to the round rollers 7, 8 via a toothed belt 29 between a gear 24 on the bearing shaft 13 and a gear 25 on an intermediate shaft 26 mounted in the pair of pivot levers 14, 15. A gear 27 is located on this , which is in engagement with a gear 28 on the axis of the round rollers 7, 8.

Während die Zahnstange 22 zum Erzeugen des Drehantriebs der Rundewalze 8 mit der Grundplatte 10a verschraubt ist, läßt sich die Position der Zahnstange 22a, von der aus der Drehantrieb der Rundewalze 7 ausgeht, auf der Grundplatte 10a in Querrichtung über eine Schiebeführung 19 verändern. Diese Verstellung ist vorgesehen für unterschiedliche Buchblockdicken und erfolgt zusammen mit der Verschiebung des die Rundewalze 7 tragenden Schwenkhebelpaares 14, wozu die Lagerböcke 11, wie aus Figur 1 ersichtlich, in einer Führungsbahn 11a auf der Tragplatte 10b verschiebbar sind bei gleichzeitiger Veränderung des Hubes der Kolbenstange 16b zum Betätigen der beiden Schwenkhebelpaare 14, 15.While the rack 22 for producing the rotary drive of the round roller 8 is screwed to the base plate 10a, the position of the rack 22a, from which the rotary drive of the round roller 7 starts, can be changed on the base plate 10a in the transverse direction via a sliding guide 19. This adjustment is provided for different book block thicknesses and takes place together with the displacement of the pair of swivel levers 14 carrying the round roller 7, for which purpose the bearing blocks 11, as can be seen in FIG. 1, can be displaced in a guideway 11a on the support plate 10b while simultaneously changing the stroke of the piston rod 16b for actuating the two pairs of swivel levers 14, 15.

Wie bereits eingangs erwähnt, wird die Einrichtung zum Rückenrunden von Buchblocks 1 mit den kontinuierlich Laufenden Klammern 2 des Buchblocktransportsystems längs der Bewegungsbahn über eine definierte Wegstrecke synchron vor- und zurückbewegt. Zur Durchführung dieser Bewegung trägt die Grundplatte 10a vertikale und horizontale Laufrollen 35, die auf Bahnen 34 des Maschinengestells laufen. An der Grundplatte 10a greift ein Antriebshebel 30 an, der an einer um Umlenkkettenräder 31 und 32 laufenden Kette 33 angelenkt ist und beim Umlauf der Kette die Grundplatte 10a vor- und zurückbewegt.As already mentioned at the beginning, the device for back-rounding book blocks 1 with the continuously running clamps 2 of the book block transport system is moved back and forth synchronously along the movement path over a defined distance. To carry out this movement, the base plate 10a carries vertical and horizontal Rollers 35, which run on tracks 34 of the machine frame. A drive lever 30 engages on the base plate 10a, which is articulated on a chain 33 running around deflection sprockets 31 and 32 and moves the base plate 10a back and forth when the chain rotates.

Es versteht sich, daß die Erfindung nicht nur auf das dargestellte Ausführungsbeispiel beschränkt ist, sondern im Rahmen der Ansprüche Abänderungen zuläßt. So ist grundsätzlich denkbar, die Antriebsmittel für die Drehbewegung der beiden Rundewalzen 7, 8 und für ihre Vertikalbewegung durch andere Mittel zu ersetzen.It goes without saying that the invention is not limited to the exemplary embodiment shown, but rather permits changes within the scope of the claims. In principle, it is conceivable to replace the drive means for the rotary movement of the two round rollers 7, 8 and for their vertical movement with other means.

Im Hinblick auf eine weitere Leistungserhöhung können in der Buchbindemaschine mehr als eine Einrichtung zum Rückenrunden hintereinander angeordnet sein, um das Rückenrunden gleichzeitig an mehreren Buchblocks durchzuführen.With a view to a further increase in performance, more than one device for rounding the back can be arranged one behind the other in the bookbinding machine in order to carry out the back rounding simultaneously on a plurality of book blocks.
