Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruches 1.The invention relates to a method according to the preamble of claim 1.

Verfahren und Vorrichtungen zum Klebebinden von Büchern sind seit langen aus dem Stand der Technik bekannt. Probleme entstehen bei herkömmlichen Klebebindeverfahren insbesondere bei Verwendung von Papier mit hoher flächenbezogener Masse. Hier hat die Praxis gezeigt, dass bei Überschreitung einer flächenbezogenen Masse von 150 g/m3 die Qualitätsanforderungen an die Haltbarkeit einer Klebeverbindung nicht mehr erfüllt werden können.Methods and apparatus for bookbinding books have long been known in the art. Problems arise in conventional adhesive binding methods, in particular when using paper with a high surface-related mass. Here, the practice has shown that when exceeding a basis weight of 150 g / m 3, the quality requirements for the durability of an adhesive bond can no longer be met.

Durch die WO 2005/023555 A2 ist bereits ein Verfahren zum Klebebinden bekannt geworden, bei dem zur Herstellung einer Klebeverbindung die zu verbindenden Blätter bzw. Druckbögen zunächst perforiert, anschließend einmal gefaltet und am Falzrand mit Klebstoff versehen werden sowie anschließend zu einem Buchblock zusammengeführt werden. Die Besonderheit liegt hierbei im Perforiervorgang, bei dem an der Falzkante zwei parallel zueinander verlaufende und in geringem Abstand voneinander angeordnete unterbrochene Perforierlinien hergestellt werden, welche in Längsrichtung, d.h. entlang der Falzkante, versetzt zueinander verlaufen und eine verbreiterte Falzkante bilden. Die beiden, parallel zueinander verlaufenden Perforierlinien weisen jeweils eine Vielzahl von Stanzschlitzen auf und bilden beispielsweise eine "Doppelschlitzperforierungslinie" aus. Die Schlitze der beiden Perforierlinien sind hierbei längs der Falzkante um die Länge eines Perforierzahnes in Längsrichtung gegeneinander versetzt. Durch Falten der Druckbögen an der perforierten, verbreiterten Falzkante und Zusammenführen der gefalteten Druckbögen zu einem Block entstehen aufgrund der "Doppelschlitzperforierungslinie" einander zugeordnete Flächen zwischen den durch die Schlitze gebildeten Ausbrüchen der einen Perforierlinie und Ausbrüchen der anderen Perforierlinie, welche ebenfalls mit Klebstoff versehen werden können. Die einmal gefalzten Druckbögen bzw. "Doppelblätter" werden mit den Ausbrüchen des jeweils anschließenden gefalzten Doppelblattes zu einem Buchblock gepresst.By the WO 2005/023555 A2 already a method for adhesive bonding has become known, in which for the production of an adhesive bond, the sheets to be joined or sheets first perforated, then folded once and provided at the edge of the fold with adhesive and then combined into a book block. The peculiarity here lies in the perforation, in which two mutually parallel and at a small distance from each other arranged discontinuous perforation are produced at the fold edge, which in the longitudinal direction, ie along the folded edge, offset from each other and form a widened folded edge. The two mutually parallel perforation lines each have a multiplicity of punched slots and form, for example, a "double slot perforation line". The slots of the two perforation lines are in this case along the folded edge offset by the length of a perforating tooth in the longitudinal direction against each other. By folding the signatures at the perforated, widened folded edge and merging the folded signatures into a block, due to the "double slot perforation line", mating surfaces are created between the apertures formed by the slots of one perforating line and outbreaks of the other perforating line, which can also be provided with adhesive , The once folded sheets or "double sheets" are pressed with the outbreaks of each subsequent folded double sheet to a book block.

CH 275 456 A offenbart ein Verfahren zum Klebebindung von Buchblöcken zur Herstellung von Büchern, bei dem zumindest ein erster und zweiter Druckbogen schlitzperforiert werden, wobei eine erste Perforierungslinie auf dem ersten Druckbogen und eine zweite Perforierungslinie auf dem zweiten Druckbogen jeweils randseitig erzeugt werden, und zwar derart, das die zweite Perforierungslinie um eine Schlitzlänge versetzt zur ersten Perforierungslinie verläuft, und die verbleibenden ersten und zweiten Druckbogenabschnitte zu einem Buchblock zusammengefügt und randseitig miteinander verklebt werden. CH 275 456 A offenbart keine Doppelperforierungslinie. CH 275 456 A discloses a method for perfect binding of book blocks for the production of books, in which at least one first and second printed sheet are perforated perforated, wherein a first perforation line on the first sheet and a second perforation on the second sheet each edge generated, in such a way that the second perforation line offset by a slot length to the first perforation line, and the remaining first and second printed sheet sections are joined together to form a book block and bonded together at the edge. CH 275 456 A does not disclose a double perforation line.

DE 10 2009 010821 A1 offenbart ein ähnliches Verfahren wie CH 275 456 A . DE 10 2009 010821 A1 discloses a similar method as CH 275 456 A ,

Aufgabe der vorliegenden Erfindung ist es ein Verfahren zum Klebebinden von Büchern anzugeben, welches eine Verarbeitung von Papier mit hoher flächenbezogener Masse, insbesondere einer flächenbezogenen Masse größer 150 g/m3 ermöglicht. Die Aufgabe wird ausgehend von den Merkmalen des Oberbegriffes des Patentanspruches 1 durch dessen kennzeichnende Merkmale gelöst.Object of the present invention is to provide a method for binding books, which allows processing of paper with high surface-related mass, in particular a basis weight greater than 150 g / m 3 . The task is achieved on the basis of the features of the preamble of claim 1 by its characterizing features.

Der wesentliche Aspekt des erfindungsgemäßen Verfahrens ist darin zu sehen, dass eine erste Doppelschlitzperforierungslinie (3) auf dem ersten Druckbogen und eine zweite Doppelschlitzperforierungslinie (4) auf dem zweiten Druckbogen jeweils randseitig erzeugt werden, und zwar derart, das die zweite Doppelschlitzperforierungslinie um eine Schlitzlänge versetzt zur ersten Doppelschlitzperforierungslinie verläuft, dass vom ersten und zweiten Druckbogen jeweils ein durch die erste bzw. zweite Doppelschlitzperforierungslinie abgeteilter streifenförmiger Randabschnitt abgetrennt wird und die verbleibenden ersten und zweiten Druckbogenabschnitte zu einem Buchblock zusammengefügt und randseitig miteinander verklebt werden. Besonders vorteilhaft werden erfindungsgemäß die zur Herstellung der Klebeverbindung vorgesehenen Randbereich der Druckbögen bogenweise derart vorbereitet, dass zusätzliche Auftragsflächen für Klebstoff entstehen, wodurch die Haltbarkeit von Klebeverbindungen, insbesondere bei Verarbeitung von Papier mit hoher flächenbezogener Masse, beispielsweise größer 150 g/m3, deutlich verbessert wird.The essential aspect of the method according to the invention can be seen in that a first double slot perforation line (3) on the first printed sheet and a second double slot perforation line (4) on the second printed sheet are respectively produced at the edge, in such a way that the second double slot perforation line is offset by one slot length extends to the first double slot perforation line that is separated from the first and second printed sheets each separated by the first and second double slot perforation strip strip-shaped edge portion and the remaining first and second printed sheet sections are joined together to form a book block and bonded together edge. According to the invention, the edge region of the signatures provided for producing the adhesive bond is particularly advantageously prepared in such a way that additional application surfaces for adhesive are formed, whereby the durability of adhesive bonds, in particular when processing paper with a high surface-related mass, for example greater than 150 g / m 3 , is markedly improved becomes.

Vorteilhaft wird durch Abtrennen des streifenförmigen Randabschnittes an der ersten bzw. zweiten Doppelschlitzperforierungslinie eine erste bzw. zweite Druckbogenkante mit einer Vielzahl von symmetrischen, vorzugsweise rechteckförmigen Ausbrüchen erzeugt, die jeweils durch die Schlitze einer Perforierungslinie einer Doppelschlitzperforierungslinie gebildet werden. Aufgrund des Versatzes der Doppelschlitzperforierungslinien zweier aneinander anschließender verbleibender Druckbogenabschnitte werden durch die Ausbrüche die jeweils gegenüberliegenden Randabschnitte der verbleibenden Druckbogenabschnitte freigestellt, welche zum Verkleben mit jeweils übernächsten verbleibender Druckbogenabschnitte mit übereinstimmenden Doppelschlitzperforierungslinie verklebt werden können. Damit entsteht neben einer erhöhten Klebefläche besonders vorteilhaft eine zusätzliche Verzahnung der Druckbögen untereinander.Advantageously, by separating the strip-shaped edge portion at the first and second double-slot perforation line respectively, a first and second sheet edge is produced having a plurality of symmetrical, preferably rectangular, apertures formed respectively by the slots of a perforation line of a double slot perforation line. Due to the offset of the Doppelschlitzperforierungslinien two adjoining remaining sheet sections are separated by the outbreaks each opposite edge portions of the remaining sheet sections, which can be glued for bonding with each remaining next sheet sections with matching Doppelschlitzperforierungslinie. This results in addition to an increased adhesive surface particularly advantageous additional teeth of the sheets with each other.

Die verbleibenden ersten und zweiten Druckbogenabschnitte werden derart zu einem Buchblock zusammengefügt, dass die erste und zweite Druckbogenkante übereinander zu liegen kommen, wobei besonders vorteilhaft die Ausbrüche der ersten und zweiten Druckbogenkante um eine Schlitzlänge versetzt zueinander erzeugt werden. Zur Herstellung eines Buchblocks werden vorzugsweise mehrere verbleibende erste und zweite Druckbogenabschnitte jeweils abwechselnd übereinander gestapelt.The remaining first and second printed sheet sections are joined together to form a book block in such a way that the first and second sheet edges come to lie one above the other, wherein the outbreaks of the first and second sheets are particularly advantageous Sheet edge generated offset by a slot length to each other. To produce a book block, preferably a plurality of remaining first and second printed sheet sections are alternately stacked one above the other.

In einer vorteilhaften Ausführungsform wird der Abstand der ersten und zweiten Perforierungslinie abhängig von der flächenbezogenen Masse des zu verarbeitenden Druckbogens gewählt, und zwar vorzugsweise im Bereich zwischen 0,3 und 0,4 mm. Dadurch kann die Tiefe der Ausbrüche zumindest teilweise erhöht oder erniedrigt werden.In an advantageous embodiment, the distance of the first and second perforation line is selected depending on the basis weight of the sheet to be processed, preferably in the range between 0.3 and 0.4 mm. As a result, the depth of the outbreaks can be at least partially increased or decreased.

Weiterhin vorteilhaft können der erste und zweite Druckbogen aus zwei rechteckförmigen Papierbögen gleichen Formats oder aus einer Papierbahn erzeugt werden, die mittels einer vorzugsweise digitalen Druckmaschine bedruckt werden. Im Falle einer Erzeugung aus Papierbögen gleichen Formats werden der erste und zweite Druckbogen bogenweise schlitzperforiert. Besonders vorteilhaft ergibt sich dadurch ein Verfahren zur automatischen Einzelfertigung von individuellen, personalisierbaren Büchern.Further advantageously, the first and second printed sheets can be produced from two rectangular paper sheets of the same format or from a paper web which are printed by means of a preferably digital printing press. In the case of production from paper sheets of the same format, the first and second printed sheets are slot-perforated arcwise. This advantageously results in a method for the automatic one-off production of individual, personalized books.

In Figur 1 ist beispielhaft ein erster und zweiter Druckbogen 1, 2 dargestellt. Zur Herstellung eines derartigen Druckbogens 1, 2 wird beispielsweise aus einer Papierbahn zumindest ein rechteckförmiger Papierbogen ausgeschnitten, welcher beispielsweise eine Breite von ca. 320 mm und eine Länge von ca. 460 mm aufweist. Bei entsprechender Breite der Papierbahn können selbstverständlich auch in einem Arbeitsschritt bereits zwei rechteckförmige Papierbögen gleichen Formats erzeugt werden. Auch sind beliebige andere rechteckförmige Formate denkbar.In FIG. 1 By way of example, a first and second printed sheets 1, 2 are shown. In order to produce such a printed sheet 1, 2, for example, at least one rectangular paper sheet is cut out of a paper web, which for example has a width of about 320 mm and a length of about 460 mm. With a corresponding width of the paper web, it is of course also possible to produce two rectangular paper sheets of the same format in one work step. Also, any other rectangular formats are conceivable.

Die rechteckförmigen Papierbögen werden vorzugsweise mittels einer digitalen Druckmaschine ein- oder zweiseitig bedruckt und ergeben damit einen ersten und zweiten Druckbogen 1, 2, die zu einem Buchblock zur Herstellung eine Buches, beispielsweise eines Fotobuches, zusammengefügt und miteinander verklebt werden. Ein derartiger Druckbogen 1, 2 weist jeweils eine erste und zweite Breitseite 1.1, 1.2, 2.1, 2.2 und eine erste und zweite Längsseite 1.3, 1.4, 2.3, 2.4 auf.The rectangular paper sheets are preferably printed on one or two sides by means of a digital printing machine and thus yield a first and second printed sheets 1, 2, which are combined to form a book block for producing a book, for example a photo book, and glued together. Such a printed sheet 1, 2 has in each case a first and second broad side 1.1, 1.2, 2.1, 2.2 and a first and second longitudinal side 1.3, 1.4, 2.3, 2.4.

Erfindungsgemäß werden der erste und zweite Druckbogen 1, 2 vor der Zusammenführung zu einem Buchblock einem Perforiervorgang unterzogen, und zwar wird die zumindest eine erste Doppelschlitzperforierungslinie 3 in den ersten Druckbogen 1 und eine zweite Doppelschlitzperforierungslinie 4 in den zweiten Druckbogen 2 eingebracht. Alternativ zur genannten bogenweisen Verarbeitung kann die erste und zweite Doppelschlitzperforierungslinie 3, 4 bereits in die Papierbahn nach dem Bedrucken eingebracht werden und anschließend der erste und zweite Druckbogen 1, 2 aus der Papierbahn hergestellt werden.According to the invention, the first and second printed sheets 1, 2 are subjected to a perforation process prior to merging into a book block, namely the at least one first double slot perforation line 3 is introduced into the first printed sheet 1 and a second double slot perforation line 4 is inserted into the second printed sheet 2. Alternatively to the aforementioned sheet-wise processing, the first and second Double slot perforation line 3, 4 are already introduced into the paper web after printing and then the first and second printed sheets 1, 2 are made from the paper web.

Die erste Doppelschlitzperforierungslinie 3 umfasst eine erste und zweite Perforierungslinie 3.1, 3.2 jeweils bestehend aus mehreren Schlitzen S mit jeweils identischer Schlitzlänge SL und Schlitzbreite SB. Die zweite Doppelschlitzperforierungslinie 4 besteht ebenfalls aus einer ersten und zweiten Perforierungslinie 4.1, 4.2, die jeweils durch mehrere Schlitze S gebildet ist, wobei auch hier die Schlitze S jeweils dieselbe Schlitzlänge SL und Schlitzbreite SB aufweisen.The first double-slot perforation line 3 comprises a first and a second perforation line 3.1, 3.2 each consisting of a plurality of slots S, each with identical slot length SL and slot width SB. The second double-slot perforation line 4 likewise consists of a first and a second perforation line 4.1, 4.2, which are each formed by a plurality of slots S, wherein here too the slots S each have the same slot length SL and slot width SB.

Der Schlitzabstand SA zweier aufeinanderfolgender Schlitze S der ersten und zweiten Doppelschlitzperforierungslinie 3, 4 ist identisch und stimmt mit der Schlitzlänge SL überein. Damit weisen die erste und zweite Doppelschlitzperforierungslinie 3, 4 einen spiegelverkehrten Verlauf auf. Die Schlitzlänge SL und der Schlitzabstand SA können zwischen 3 mm und 5 mm betragen, wobei die Schlitzbreite SB zwischen 0,1 mm und 0,3 mm liegt.The slot pitch SA of two successive slots S of the first and second double-slot perforation lines 3, 4 is identical and coincides with the slot length SL.

The slot length SL and the slot spacing SA can be between 3 mm and 5 mm, the slot width SB being between 0.1 mm and 0.3 mm.

Die erste und zweite Perforierungslinie 3.1, 3.2 der ersten Doppelschlitzperforierungslinie 3 sowie die erste und zweite Perforierungslinie 4.1, 4.2 der zweiten Doppelschlitzperforierungslinie 4 verlaufen jeweils parallel zueinander, und zwar entlang einer Längsachse LA. Die erste und zweite Perforierungslinie 3.1, 3.2, 4.1, 4.2 einer Doppelschlitzperforierungslinie 3, 4 weisen jeweils einen Abstand D von ca. 0,3 mm bis 0,4 mm auf, der vorzugsweise abhängig von der flächenbezogenen Masse des zu verarbeitenden Druckbogens bzw. zu dessen Herstellung gewählten Papierbahn gewählt wird.The first and second perforation lines 3.1, 3.2 of the first double slot perforation line 3 and the first and second perforation lines 4.1, 4.2 of the second double slot perforation line 4 each extend parallel to one another, along a longitudinal axis LA. The first and second perforation line 3.1, 3.2, 4.1, 4.2 of a Doppelschlitzperforierungslinie 3, 4 each have a distance D of about 0.3 mm to 0.4 mm, preferably depending on the basis weight of the sheet to be processed or to whose production is chosen selected paper web.

In Fig. 2 und Fig. 3a, b ist jeweils in schematischen Darstellungen der Aufbau der ersten und zweiten Perforierungslinie 3.1, 3.2 der ersten Doppelschlitzperforierungslinie 3 sowie der ersten und zweiten Perforierungslinie 4.1, 4.2 der zweiten Doppelschlitzperforierungslinie 4 dargestellt. Fig. 2 zeigt beispielsweise eine vergrößerte Ausschnittsdarstellung einer Draufsicht auf die linke untere Ecke des ersten und zweiten Druckbogens 1, 2 der Figur 1.In Fig. 2 and Fig. 3a, b The structure of the first and second perforation line 3.1, 3.2 of the first double slot perforation line 3 and of the first and second perforation line 4.1, 4.2 of the second double slot perforation line 4 is illustrated in schematic representations. Fig. 2 shows, for example, an enlarged sectional view of a plan view of the lower left corner of the first and second printing sheets 1, 2 of FIG. 1 ,

Erfindungsgemäß werden die erste und zweite Doppelschlitzperforierungslinie 3, 4 randseitig im ersten bzw. zweiten Druckbogen 1, 2 eingebracht, d.h. verlaufen entlang und vorzugsweise parallel zu einer der Breitseiten 1.1, 1.2, 2.1, 2.2 oder einer der Längsseiten 1.3, 1.4, 2.3, 2.4 des ersten und zweiten Druckbogens 1, 2.According to the invention, the first and second double-slot perforation lines 3, 4 are introduced peripherally in the first and second printing sheets 1, 2, i. run along and preferably parallel to one of the broad sides 1.1, 1.2, 2.1, 2.2 or one of the longitudinal sides 1.3, 1.4, 2.3, 2.4 of the first and second printing sheets 1, 2.

Im vorliegenden Ausführungsbeispiel sind die erste und zweite Doppelschlitzperforierungslinie 3, 4 beispielhaft am linken Rand des ersten bzw. zweiten Druckbogens 1, 2 vorgesehen und verlaufen damit unmittelbar benachbart zur ersten Längsseite 1.3, 2.3 des ersten bzw. zweiten Druckbogens 1, 2.In the present exemplary embodiment, the first and second double slot perforation lines 3, 4 are provided, for example, on the left edge of the first and second printing sheets 1, 2 and thus extend immediately adjacent to the first longitudinal side 1.3, 2.3 of the first and second printing sheets 1, 2.

Durch die erste bzw. zweite Doppelschlitzperforierungslinie 3, 4 wird der erste und zweite Druckbogen 1, 2 in zwei Abschnitte aufgeteilt, und zwar einen streifenförmigen Randabschnitt 1', 2' und einen verbleibenden ersten und zweiten Druckbogenabschnitt 1", 2", der zur Herstellung des Buchblockes Verwendung findet, wohingegen der streifenförmige Randabschnitt 1', 2' als Abfall entsorgt wird. Der streifenförmige Randabschnitt 1', 2' weist im Vergleich zum verbleibenden Druckbogenabschnitt 1", 2" daher eine geringe Breite auf, vorzugsweise im Bereich zwischen 5 und 30 mm.By the first and second double slot perforation line 3, 4, the first and second printing sheets 1, 2 is divided into two sections, namely a strip-shaped edge portion 1 ', 2' and a remaining first and second printed sheet section 1 ", 2", for the production the book block is used, whereas the strip-shaped edge portion 1 ', 2' is disposed of as waste. The strip-shaped edge portion 1 ', 2' therefore has a small width, preferably in the range between 5 and 30 mm, in comparison to the remaining printed-sheet portion 1 ", 2".

Mittels der ersten und zweiten Doppelschlitzperforierungslinie 3, 4 ist jeweils der streifenförmige Randabschnitt 1', 2' vom verbleibenden Druckbogenabschnitt 1", 2" schnell und einfach zu trennen, und zwar näherungsweise entlang der Längsachse LA der ersten und zweiten Doppelschlitzperforierungslinie 3, 4. In Figur 3 ist beispielhaft eine Draufsicht auf den linken unteren Eckabschnitt des ersten Druckbogens 1 dargestellt, und zwar einmal vor und nach dem Abtrennen des streifenförmigen Randabschnittes 1' vom verbleibenden Druckbogenabschnitt 1".By means of the first and second double slot perforation lines 3, 4, the strip-shaped edge section 1 ', 2' can be quickly and easily separated from the remaining sheet section 1 ", 2", approximately along the longitudinal axis LA of the first and second double slot perforation lines 3, 4 FIG. 3 For example, a plan view of the left lower corner portion of the first printing sheet 1 is shown, once before and after the separation of the strip-shaped edge portion 1 'from the remaining sheet portion 1 ".

Durch Abtrennen des streifenförmigen Randabschnittes 1', 2' entsteht aufgrund der ersten bzw. zweiten Doppelschlitzperforierungslinie 3, 4 eine erste bzw. zweite Druckbogenkante 5, 6 mit einer Vielzahl von gleichartigen, vorzugsweise rechteckförmigen Ausbrüchen A. Die Ausbrüche A der ersten und zweiten Druckbogenkanten 5, 6 werden jeweils durch die Schlitze S der Doppelschlitzperforierungslinie 3, 4, und zwar vorzugsweise durch die Schlitze S der ersten Perforierungslinie 3.1, 4.1 gebildet. Die Ausbrüche A weisen eine Ausbruchbreite AB und eine Ausbruchtiefe TA auf und sind in einem Ausbruchabstand AA zueinander angeordnet. Näherungsweise ist die Ausbruchtiefe AT gleich der Schlitzbreite SB der Doppelschlitzperforierungslinie 3, 4 und beträgt zwischen 0,1 mm und 0,3 mm. Die Ausbruchbreite AB entspricht der Schlitzlänge SL, wobei der Ausbruchabstand AA durch den Schlitzabstand SA vorgegeben ist und damit mit der Ausbruchbreite AB übereinstimmt.By separating the strip-shaped edge portion 1 ', 2' arises due to the first and second double slot perforation line 3, 4, a first and second sheet edge 5, 6 with a plurality of similar, preferably rectangular outbreaks A. The outbreaks A of the first and second sheet edges. 5 , 6 are each formed by the slots S of the double slot perforation line 3, 4, preferably through the slots S of the first perforation line 3.1, 4.1. The outbreaks A have an excavation width AB and a excavation depth TA and are at an outbreak distance AA to each other arranged. Approximately, the excavation depth AT is equal to the slot width SB of the double slot perforation line 3, 4 and is between 0.1 mm and 0.3 mm. The break-out width AB corresponds to the slot length SL, wherein the break-out distance AA is predetermined by the slot spacing SA and thus coincides with the break-out width AB.

Durch die Ausbrüche A entstehen nach außen abstehende Flanschabschnitte F, deren Flächeninhalt näherungsweise mit dem Flächeninhalt der Ausbrüche A übereinstimmt. Der sich in Draufsicht ergebende rechteckförmige Verlauf der Druckbogenkanten 5, 6 ist beim ersten verbleibenden Druckbogenabschnitt 1" im Vergleich zum zweiten verbleibenden Druckbogenabschnitt 2" um eine Schlitzlänge SL bzw. eine Ausbruchbreite AB versetzt.By the outbreaks A arise outwardly projecting flange sections F, the surface area corresponds approximately with the surface area of the outbreaks A. The resulting in plan view rectangular shape of the sheet edges 5, 6 is the first remaining sheet section 1 "compared to the second remaining sheet section 2" offset by a slit length SL and an outbreak width AB.

Die verbleibenden ersten und zweiten Druckbogenabschnitte 1", 2" werden anschließend derart zu einem Buchblock zusammengefügt, dass die erste und zweite Druckbogenkante 5, 6 übereinander zu liegen kommen. Aufgrund der Verschiebung um eine Schlitzlänge SL bzw. eine Ausbruchbreite AB schließen die Ausbrüche A der bzgl. der verbleibenden Längs- und Querseiten bündig übereinander liegenden ersten und zweiten verbleibenden Druckbogenabschnitte 1", 2" abwechselnd aneinander an, und zwar derart, dass die jeweils zwei Ausbrüche A miteinander verbindenden Flanschabschnitte F des übereinander liegenden ersten und zweiten verbleibenden Druckbogenabschnitte 1", 2" eine geschlossene Bogenkante ausbilden.The remaining first and second printed sheet sections 1 ", 2" are then joined together to form a book block such that the first and second printed sheet edges 5, 6 come to lie one above the other. Because of the shift by one slit length SL or an outbreak width AB, the outbreaks A alternately adjoin one another with respect to the remaining longitudinal and transverse sides of the first and second remaining sheet sections 1 ", 2" lying flush one above the other, in such a way that the respective two Outbreaks A interconnecting flange portions F of the superimposed first and second remaining sheet sections 1 ", 2" form a closed arc edge.

Durch die Ausbrüche A des zweiten verbleibenden Druckbogenabschnittes 2" werden die Flanschabschnitte F des darunter liegenden ersten verbleibenden Druckbogenabschnittes 1" freigelegt, so dass diese mit den Flanschabschnitten F eines weiteren, ersten verbleibenden Druckbogenabschnittes 1", der im Buchblock dem zweiten verbleibenden Druckbogenabschnitt 2" folgt, verklebt werden können. Analog hierzu können die Flanschabschnitte F des zweiten verbleibenden Druckbogenabschnittes 2" mit den Flanschabschnitten eines weiteren, zweiten verbleibenden Druckbogenabschnittes 2" verklebt werden, zwischen denen ein erster verbleibender Druckbogenabschnitt 1" aufgenommen ist bzw. von diesen teilweise umschlossen wird.Through the breakouts A of the second remaining sheet section 2 ", the flange portions F of the underlying first remaining sheet section 1" are exposed to follow the flange sections F of another first printed sheet section 1 "following the second remaining sheet section 2" in the book block , can be glued. Analogously thereto, the flange sections F of the second remaining printed sheet section 2 "can be bonded to the flange sections of a further, second remaining printed sheet section 2", between which a first remaining printed sheet section 1 "is received or partially enclosed by the latter.

Zur Herstellung eines Buchblocks werden vorzugsweise mehrere, zumindest zwei verbleibende erste Druckbogenabschnitte 1" und zwei verbleibende zweite Druckbogenabschnitte 1", 2" jeweils abwechselnd übereinander gelegt. Die jeweils durch die Ausbrüche A der zweiten verbleibenden Druckbogenabschnitt 2" freigestellten Flanschabschnitt F der ersten erbleibenden Druckbogenabschnitte 1" und analog hierzu die durch die Ausbrüche A der ersten verbleibenden Druckbogenabschnitt 1" freigestellten Flanschabschnitte F des zweiten verbleibenden Druckbogenabschnittes 2" werden im Buchblock jeweils miteinander verklebt und damit eine höchst widerstandsfähige Klebeverbindung zwischen den einzelnen verbleibenden Druckbogenabschnitten 1", 2" erreicht. Insbesondere ergibt sich eine Art "Verzahnung" jeweils aneinander anschließender verbleibenden Druckbogenabschnitte 1 ", 2". Ferner entsteht an der zur Klebebindung vorgesehenen Stirnseite des Buchblockes eine schachbrettartige Anordnung von Ausbrüchen A, in welche besonders einfach und effizient Klebemittel eingebracht werden kann.To produce a book block, preferably at least two remaining first printed-sheet sections 1 "and two remaining second printed-sheet sections 1", 2 "are alternately superimposed the outbreaks A of the second remaining sheet section 2 "exempted flange portion F of the first surviving sheet sections 1" and analogous thereto by the outbreaks A of the first remaining sheet section 1 "exempted flange portions F of the second remaining sheet section 2" are glued together in the book block and thus one achieved highly resistant adhesive bond between the individual remaining sheet sections 1 ", 2". In particular, a kind of "toothing" results in each of the adjoining remaining sheet sections 1 ", 2". Furthermore, a checkerboard-like arrangement of outbreaks A, in which adhesives can be introduced in a particularly simple and efficient manner, is produced on the end face of the book block intended for adhesive bonding.

Figur 6 zeigt beispielhaft eine perspektivische Ansicht übereinander liegender erster und zweiter verbleibenden Druckbogenabschnitte 1 ", 2", welche einen Buchblock bilden. Die Ausbrüche A sind hierbei strichliert und die Kanten der Flanschabschnitte F ohne Füllmuster gezeichnet, damit die die schachbrettartige Anordnung der Ausbrüche A deutlich ersichtlich wird. Die dargestellte Anordnung ermöglicht ein unmittelbares Verkleben eines verbleibenden Druckbogenabschnittes 1" mit den übernächsten verbleibenden Druckbogenabschnitt 1 " gleichen Perforierungstyps. FIG. 6 shows by way of example a perspective view of superimposed first and second remaining sheet sections 1 ", 2", which form a book block. The outbreaks A are here dashed lines and the edges of the flange sections F drawn without filling pattern, so that the checkerboard-like arrangement of the outbreaks A is clearly visible. The illustrated arrangement allows a direct bonding of a remaining sheet section 1 "with the remaining next sheet press section 1" same perforation type.

Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, dass zahlreiche Modifikationen und Abwandlungen der Erfindung möglich sind, ohne dass hierdurch der Erfindungsgedanke, wie in der Ansprüchen definiert, verlassen wird.The invention has been described above by means of an embodiment. It should be understood that numerous modifications and variations of the invention are possible without departing from the spirit of the invention as defined in the claims.
