Definitions
- the invention relates to a book in the form of a brochure, with a book block of sheets held together on the spine and a flexible cover comprising the book block, the front and rear cover sheets of which, directly or indirectly, each with the first or last sheet of the book block, at least in the adjacent region of the book block spine edges are connected, the back of the cover being at least largely spaced from the back of the book block when the book is opened.
- Another disadvantage of the known book is that when the cover is opened, high tensile forces act directly on the connection between the first sheet of the book block and the latter itself. Due to the stiffness of the cover, this connection is particularly at risk and if a book that is only glued is used several times, the first sheet and the last sheet of the book block can separate from it.
- the object of the invention is to develop a book of the type mentioned in such a way that, while maintaining a good opening behavior, an improvement in the optical appearance, in particular in the case of thick brochures, and at the same time a higher production reliability when cutting the brochures is achieved.
- the stiffening of the back of the lid is achieved by gluing it on the inside with a reinforcement strip which extends over essentially the full back width of the lid.
- This reinforcement strip preferably consists of largely non-fibrous material. If, in the simplest case, a cardboard strip is used as the reinforcement strip, this should be achieved by finishing the surface of the strip, e.g. B. solidified by film lamination, UV coating or the like.
- the hardening with a hardenable material is applied in a liquid or plastic state and that after hardening there is a hardening of the back of the lid.
- the advantage of the invention is that with this stiffening of the back of the cover, unraveling or tearing out during later cutting of the finished brochure is almost completely ruled out.
- the immediate consequence is a better appearance of the book compared to the book of the type mentioned at the beginning. This good appearance remains preserved even after a long period of use of the book.
- the cover spine on the side facing the book block spine and / or this itself has adhesive means, due to which the cover spine is firmly connected to the book block spine when the book is closed, at least before it is opened for the first time, and the adhesive effect of which is sufficiently small to prevent damage Unfold the book to allow detachment of the book block spine from the cover spine.
- the adhesive or adhesives comprise a permanent pressure-sensitive adhesive which allows the back of the cover to be re-bonded to the back of the book block at least several times when the book is closed.
- this embodiment of the invention differs from the prior art mentioned at the outset, in which the spine of the book block is not glued to the spine of the cover, rather the cover is also glued to the back as in a simple cardboard brochure.
- the reinforcement or stiffening of the back of the lid and a refinement of this back reinforcement according to the invention now make permanent, permanent bonding prevented from the cover spine on the book block spine. During the cutting process, the connection is so tight that problem-free cutting is ensured and fraying is prevented.
- the brochure has an exactly angular shape. Due to the extremely high bending stiffness of the cover spine as a result of the back reinforcement, the cover spine cannot adapt to the movement of the book block spine when the brochure is opened.
- the tensile forces are higher than the relatively low adhesive force, which is why the spine of the book block separates from the spine of the cover when the brochure is opened.
- the adhesive effect of the adhesive is preferably chosen so that the book block spine is re-glued to the cover spine when the brochure is closed. This increases the durability of the brochure and the appearance of the brochure is that of a high-quality book.
- a book block can be made with or without a backing layer, the so-called folder. If such a backing support layer is used, this is - as in the prior art mentioned at the beginning - wrapped around the book block and glued to the first and last sheet of the book block or covers only the back of the book block.
- connection of the cover sheets with the book block can take place on the fold or on the first and last sheets of the book block or on both areas.
- adhesive-bound products With adhesive-bound products, the risk of tearing out the first sheet when opening the book is reduced, but not eliminated.
- the good opening behavior of a book block, on the back of which no cardboard cover is glued leads one to open such a book as flat as possible from the start.
- very high tensile forces are then transferred to the adhesive connection between the first sheet glued to the cover and the book block.
- the first and the last sheet of the book block are each glued to one sheet (inner sheet) of a folded double sheet (leading or trailing), to the other sheet (outer sheet) the respective cover sheet is glued.
- the fold of each double sheet can be arranged flush with the book block spine, but is preferably arranged at a distance from the respective edge of the book block spine and it is further provided that in this area the cover sheets each have a fold groove or a pair of fold grooves. The cover is no longer directly on the book block and thus glued to the critical first and last sheet but to the outer sheet of the preferably broadly glued header or trailer.
- the tensile forces of the cover can thus be fully transferred to these two outer sheets when the cover is opened, without a substantial transfer of force being exerted on the inner sheet of the header or trailer. From this inner sheet almost no forces act on the first or last sheet of the book block. This means that it does not require a backing layer on the back, which makes production cheaper overall.
- the book 10 shown in the drawing consists of a book block 12 and a cover 14, the two cover sheets 16, 18 and a lid back 20.
- the book block 12 is shown here with a fold 22 on the back, which is glued to the rear edges of the sheets of the book block 12 by means of a glue layer 24.
- the fold is turned over at the front and back and additionally glued in the cover areas on the first sheet 26 and on the last sheet 28.
- a glue interspersed with fleece fibers can be used, which after hardening has a similar function to the combination of glue and felling.
- a reinforcing strip 32 is firmly adhered to the back 20 of the cover by means of an adhesive layer 30, which, for example, consists of a cardboard strip, the width of which essentially corresponds to that of the back of the cover 20.
- This reinforcing strip 32 has a finish on its free surface, for example in the form of a film lamination 34. With this back reinforcement of the cover 14, a stabilization is achieved which, when cutting the book, unraveling. Tear out prevented.
- the surface of the finishing layer 34 additionally has a pressure-sensitive adhesive layer 36 which interacts with an adhesive layer 38 which is located on the free surface of the back of the fold 22.
- the two adhesive layers 36, 38 are firmly connected to one another, so that the book block 12 is fastened to the back cover 20.
- This firm connection permits problem-free cutting of the book, so that the brochure has an exactly angular shape which is retained even when in use, with no clearly visible gap between the book block spine 12a and the cover spine 20 when the book is closed.
- the book block spine 12a first lifts in the middle from the cover spine 20, since this is extremely rigid due to the reinforcing strip 32.
- the gap is formed between the two adhesive layers 36, 38 and when opened further, the book block spine 12a is completely detached from the cover spine 20 and stands out from the latter.
- the two adhesive layers 36, 38 come into contact again and a new adhesive bond occurs between the book block spine 12a and the cover spine 20.
- the cover sheets 16, 18 are connected to the first sheet 26 and the last sheet 28 of the book block 12 via so-called prefixes and suffixes.
- the attachment consists of a double sheet 40, 42, which has a fold 44 at a distance from the block back edge.
- the outer sheet 40 is connected to the cover 16 over a wide area by means of an adhesive strip 46, while the inner sheet 42, also over a wide area, is connected to the first sheet 26 of the book block 12 by means of an adhesive layer 48.
- the cover sheet 16 has a fold groove 50, so that when the book is opened, the cover 16 pivots about this fold groove 50, thereby transmitting the tensile force to the outer sheet 40 of the attachment.
- a hinge is formed on the fold 44 of the double sheet 40, 42.
- the opening of the cover sheet 16 exerts practically no tensile stress on the first sheet 26 of the book block 12. A risk of tearing out the first sheet 26 or last sheet 28 from the spine of the book block is thus eliminated.
- the back cover 18 is also glued to the last sheet 28 of the book block 12 by means of a double sheet 52, 54 in the same way as the attachment.
- the first and last paragraphs can also overlap the folded parts of the felling or vice versa.
- the folds 44 of the double sheets can reach up to the back edge.

Abstract
Description
Die Erfindung betrifft ein Buch in Form einer Broschur, mit einem Buchblock aus am Rücken zusammengehaltenen Blättern und einem, den Buchblock umfassenden biegsamen Deckel, dessen vordere und hintere Deckelblätter unmittelbar oder mittelbar jeweils mit dem ersten bzw. letzten Blatt des Buchblockes mindestens im Nachbarbereich der Buchblockrückenkanten verbunden sind, wobei der Deckelrücken bei aufgeschlagenem Buch wenigstens zum größten Teil vom Buchblockrücken beabstandet ist.The invention relates to a book in the form of a brochure, with a book block of sheets held together on the spine and a flexible cover comprising the book block, the front and rear cover sheets of which, directly or indirectly, each with the first or last sheet of the book block, at least in the adjacent region of the book block spine edges are connected, the back of the cover being at least largely spaced from the back of the book block when the book is opened.
Ein derartiges Buch ist aus der DE 29 36 674 A 1 bekannt. Da der Buchblockrücken mit dem Deckelrücken nicht fest verbunden ist, wird der Deckelrücken beim Aufschlagen des Buches nicht geknickt und nicht beschädigt. Außerdem hat das Buch ein gutes Aufschlagverhalten, d.h. ein aufgeschlagenes Buch neigt weniger zum selbsttätigen Zuschlagen. Allerdings ist das Buch insofern noch verbesserungsbedürftig, als bei der Herstellung Probleme auftreten. Der Deckelrücken neigt beim Pressen der Broschur während des Schneidvorganges dazu, sich vom Blockrücken abzuspalten. Beim Schneiden in der Dreimessermaschine führt dies sehr häufig zu einem Ausreißen des Deckels am Buchblockrücken. Je dünner das Deckelmaterial ist, desto häufiger und stärker tritt diese Erscheinung auf. Das spaltförmige Abstehen des Deckelrückens vom Buchblockrücken verschlechtert in Verbindung mit dem unsauberen Schnittbild den optischen Eindruck der Broschur. Dieser Nachteil verstärkt sich mit zunehmender Buchdicke und auch beim Gebrauch des Buches.Such a book is known from DE 29 36 674 A1. Since the spine of the book block is not firmly connected to the spine of the cover, the spine of the cover is not kinked or damaged when the book is opened. In addition, the book has a good opening behavior, ie a opened book is less likely to strike automatically. However, the book is still in need of improvement in that there are problems with the production. The back of the cover tends to split off from the back of the block when the brochure is pressed during the cutting process. When cutting in the three-knife machine, this very often leads to the cover being torn out Book block spine. The thinner the lid material, the more frequent and stronger this phenomenon occurs. The gap-like protrusion of the back of the cover from the back of the book block, in conjunction with the unclean cut, worsens the visual impression of the brochure. This disadvantage increases with increasing book thickness and also when using the book.
Ein weiterer Nachteil des bekannten Buches besteht darin, daß beim Aufschlagen des Deckels hohe Zugkräfte unmittelbar auf die Verbindung zwischen erstem Blatt des Buchblockes und diesem selbst einwirken. Aufgrund der Steifigkeit des Deckels ist diese Verbindung besonders gefährdet und bei mehrmaligem Gebrauch eines nur klebegebundenen Buches können sich das erste Blatt und das letzte Blatt des Buchblockes von diesem abspalten.Another disadvantage of the known book is that when the cover is opened, high tensile forces act directly on the connection between the first sheet of the book block and the latter itself. Due to the stiffness of the cover, this connection is particularly at risk and if a book that is only glued is used several times, the first sheet and the last sheet of the book block can separate from it.
Aufgabe der Erfindung ist es, ein Buch der eingangs genannten Art dahingehend auszubilden, daß unter Beibehaltung eines guten Aufschlagverhaltens eine Verbesserung des optischen Erscheinungsbildes insbesondere bei dickeren Broschuren und gleichzeitig eine höhere Produktionssicherheit beim Schneiden der Broschuren erreicht wird.The object of the invention is to develop a book of the type mentioned in such a way that, while maintaining a good opening behavior, an improvement in the optical appearance, in particular in the case of thick brochures, and at the same time a higher production reliability when cutting the brochures is achieved.
Diese Aufgabe wird bei einem Buch mit den Merkmalen des Oberbegriffes von Patentanspruch 1 dadurch gelöst, daß der Deckelrücken biegesteifer ausgebildet ist, als mindestens der größte Teil wenigstens eines der Deckelblätter.This object is achieved in a book with the features of the preamble of claim 1 in that the cover spine is more rigid than at least the largest part of at least one of the cover sheets.
Gemäß einer Ausgestaltung der Erfindung wird die Versteifung des Deckelrückens dadurch erreicht, daß dieser innenseitig mit einem Verstärkungsstreifen verklebt ist, der sich über im wesentlichen die volle Rückenbreite des Deckels erstreckt.Dieser Verstärkungsstreifen besteht vorzugsweise aus weitestgehend nichtfaserndem Material. Wird im einfachsten Fall als Verstärkungsstreifen ein Kartonstreifen verwendet, so sollte dieser durch Veredelung der Oberfläche des Streifens, z. B. durch Folienkaschierung, UV-Lackierung oder Ahnliches verfestigt werden.According to one embodiment of the invention, the stiffening of the back of the lid is achieved by gluing it on the inside with a reinforcement strip which extends over essentially the full back width of the lid. This reinforcement strip preferably consists of largely non-fibrous material. If, in the simplest case, a cardboard strip is used as the reinforcement strip, this should be achieved by finishing the surface of the strip, e.g. B. solidified by film lamination, UV coating or the like.
Es liegt auch im Rahmen der Erfindung, daß die Verfestigung mit einem aushärtbaren Material in flüssigem oder plastischem Zustand aufgebracht wird und nach der Aushärtung eine Verfestigung des Deckelrückens ergibt.It is also within the scope of the invention that the hardening with a hardenable material is applied in a liquid or plastic state and that after hardening there is a hardening of the back of the lid.
Der Vorteil der Erfindung besteht darin, daß mit dieser Versteifung des Deckelrückens ein Ausfasern bzw. Ausreißen beim späteren Schneiden der fertigen Broschur nahezu vollständig ausgeschlossen wird. Die unmittelbare Folge ist ein besseres Erscheinungsbild des Buches im Vergleich zu dem Buch der eingangs genannten Art. Dieses gute Erscheinungsbild bleibt auch nach längerer Gebrauchszeit des Buches erhalten.The advantage of the invention is that with this stiffening of the back of the cover, unraveling or tearing out during later cutting of the finished brochure is almost completely ruled out. The immediate consequence is a better appearance of the book compared to the book of the type mentioned at the beginning. This good appearance remains preserved even after a long period of use of the book.
Gemäß einem weiteren Aspekt der Erfindung weisen der Deckelrücken an der dem Buchblockrücken zugewandten Seite und / oder dieser selbst Haftmittel auf, aufgrund deren der Deckelrücken mit dem Buchblockrücken bei geschlossenem Buch wenigstens vor dessen erstmaligem Aufklappen fest verbunden ist und deren Haftwirkung ausreichend klein ist, um beim Aufklappen des Buches ein Ablösen des Buchblockrückens vom Deckelrücken zu erlauben. Eine Weiterbildung hierzu besteht darin, daß das oder die Haftmittel einen Dauerhaftkleber umfassen, der eine mindestens mehrmalige Wiederverklebung des Deckelrückens mit dem Buchblockrücken bei geschlossenem Buch erlaubt. Mit dieser Ausgestaltung der Erfindung unterscheidet sich diese vom eingangs genannten Stand der Technik, bei dem der Buchblockrücken nicht mit dem Deckelrücken verklebt ist, vielmehr wird der Deckel wie bei einer einfachen Kartonbroschur auch am Rücken angeklebt. Durch die erfindungsgemäße Verstärkung bzw. Versteifung des Deckelrückens und eine Veredelung dieser Rückenverstärkung wird nun aber eine dauerhaft feste Verklebung vom Deckelrücken am Buchblockrücken verhindert. Beim Schneidvorgang ist die Verbindung so fest, daß ein problemloses Schneiden sichergestellt und ein Ausfransen ausgeschlossen ist. Die Broschur hat eine exakt kantige Form. Bedingt durch die infolge Rückenverstärkung extrem hohe Biegesteifigkeit des Deckelrückens kann sich beim Aufschlagen der Broschur der Deckelrücken der Bewegung des Buchblockrückens nicht anpassen. Die Zugkräfte sind höher als die relativ geringe Haftkraft, weswegen sich der Buchblockrücken vom Deckelrücken löst, wenn die Broschur aufgeschlagen wird. Die Haftwirkung der Haftmittel wird vorzugsweise so gewählt, daß ein erneutes Verkleben des Buchblockrückens mit dem Deckelrücken stattfindet, wenn die Broschur zugeschlagen wird. Die Widerstandsfähigkeit der Broschur wird dadurch erhöht und das Erscheinungsbild der Broschur ist das eines hochwertigen Buches.According to a further aspect of the invention, the cover spine on the side facing the book block spine and / or this itself has adhesive means, due to which the cover spine is firmly connected to the book block spine when the book is closed, at least before it is opened for the first time, and the adhesive effect of which is sufficiently small to prevent damage Unfold the book to allow detachment of the book block spine from the cover spine. A further development in this regard is that the adhesive or adhesives comprise a permanent pressure-sensitive adhesive which allows the back of the cover to be re-bonded to the back of the book block at least several times when the book is closed. With this embodiment of the invention, this differs from the prior art mentioned at the outset, in which the spine of the book block is not glued to the spine of the cover, rather the cover is also glued to the back as in a simple cardboard brochure. The reinforcement or stiffening of the back of the lid and a refinement of this back reinforcement according to the invention now make permanent, permanent bonding prevented from the cover spine on the book block spine. During the cutting process, the connection is so tight that problem-free cutting is ensured and fraying is prevented. The brochure has an exactly angular shape. Due to the extremely high bending stiffness of the cover spine as a result of the back reinforcement, the cover spine cannot adapt to the movement of the book block spine when the brochure is opened. The tensile forces are higher than the relatively low adhesive force, which is why the spine of the book block separates from the spine of the cover when the brochure is opened. The adhesive effect of the adhesive is preferably chosen so that the book block spine is re-glued to the cover spine when the brochure is closed. This increases the durability of the brochure and the appearance of the brochure is that of a high-quality book.
Ein Buchblock kann mit oder ohne rückseitiger Stützschicht, dem sogenannten Fälzel, hergestellt werden. Wird eine solche rückseitige Stützschicht verwendet, so ist diese - wie auch beim eingangs genannten Stand der Technik - um den Buchblock herumgeschlagen und am ersten und letzten Blatt des Buchblockes verleimt oder überdeckt nur den Rücken des Buchblockes.A book block can be made with or without a backing layer, the so-called folder. If such a backing support layer is used, this is - as in the prior art mentioned at the beginning - wrapped around the book block and glued to the first and last sheet of the book block or covers only the back of the book block.
Die Verbindung der Deckelblätter mit dem Buchblock kann am Fälzel oder an den ersten und letzten Blättern des Buchblockes erfolgen bzw. an beiden Bereichen. Dadurch ist bei klebegebundenen Produkten die Ausreißgefahr des ersten Blattes beim Aufschlagen des Buches zwar gemildert, aber nicht ausgeschaltet. Insbesondere das gute Aufschlagverhalten eines Buchblockes, an dessen Rücken kein Kartonumschlag angeklebt ist, verleitet dazu, ein solches Buch von Anfang an möglichst flach aufzuschlagen. Beim Aufschlagen des vorderen Umschlagdeckels werden dann aber sehr hohe Zugkräfte auf die Klebeverbindung zwischen dem ersten an dem Umschlag angeklebten Blatt und den Buchblock übertragen.The connection of the cover sheets with the book block can take place on the fold or on the first and last sheets of the book block or on both areas. With adhesive-bound products, the risk of tearing out the first sheet when opening the book is reduced, but not eliminated. In particular, the good opening behavior of a book block, on the back of which no cardboard cover is glued, leads one to open such a book as flat as possible from the start. When the front cover is opened, however, very high tensile forces are then transferred to the adhesive connection between the first sheet glued to the cover and the book block.
Um diesen Nachteil auszuschalten, ist erfindungsgemäß vorgesehen, daß das erste und das letzte Blatt des Buchblockes je mit einem Bogen (inneres Blatt) eines gefalzten Doppelbogens (Vor- bzw. Nachsatz) verklebt sind, an dessen anderem Bogen (äußeres Blatt) das jeweilige Deckelblatt angeklebt ist. Der Falz jedes Doppelbogens kann dabei mit dem Buchblockrücken bündig angeordnet sein, wird jedoch vorzugsweise im Abstand von der jeweiligen Kante des Buchblockrückens angeordnet und es ist weiterhin vorgesehen, daß in diesem Bereich die Deckelblätter jeweils eine Faltrille oder ein Faltrillenpaar aufweisen. Der Deckel wird also nicht mehr unmittelbar am Buchblock und damit am kritischen ersten und letzten Blatt angeklebt sondern am jeweils äußeren Bogen des vorzugsweise breit angeklebten Vor- bzw. Nachsatzes. Die Zugkräfte des Umschlagens können beim Aufschlagen des Deckels somit voll auf diese beiden äußeren Bogen übertragen werden, ohne daß eine wesentliche Kraftübertragung auf den inneren Bogen des Vor- bzw. Nachsatzes ausgeübt wird. Von diesem inneren Bogen wirken nahezu keine Kräfte mehr auf das erste bzw. letzte Blatt des Buchblockes. Dieser benötigt somit keine rückseitige Stützschicht, wodurch sich die Herstellung insgesamt verbilligt.In order to eliminate this disadvantage, it is provided according to the invention that the first and the last sheet of the book block are each glued to one sheet (inner sheet) of a folded double sheet (leading or trailing), to the other sheet (outer sheet) the respective cover sheet is glued. The fold of each double sheet can be arranged flush with the book block spine, but is preferably arranged at a distance from the respective edge of the book block spine and it is further provided that in this area the cover sheets each have a fold groove or a pair of fold grooves. The cover is no longer directly on the book block and thus glued to the critical first and last sheet but to the outer sheet of the preferably broadly glued header or trailer. The tensile forces of the cover can thus be fully transferred to these two outer sheets when the cover is opened, without a substantial transfer of force being exerted on the inner sheet of the header or trailer. From this inner sheet almost no forces act on the first or last sheet of the book block. This means that it does not require a backing layer on the back, which makes production cheaper overall.

Das in der Zeichnung dargestellte Buch 10 besteht aus einem Buchblock 12 und einem Deckel 14, der zwei Deckelblätter 16, 18 und einen Deckelrücken 20 aufweist. Der Buchblock 12 ist hier mit einem rückseitigen Fälzel 22 dargestellt, welches mittels einer Leimschicht 24 mit den rückseitigen Kanten der Blätter des Buchblockes 12 verklebt ist. Das Fälzel ist vorn und hinten umgeschlagen und zusätzlich in den Umschlagbereichen am ersten Blatt 26 und am letzten Blatt 28 angeleimt.The
Es ist aber ausdrücklich darauf hinzuweisen, daß ein solches Fälzel 22 bei dem erfindungsgemäßen Buch entbehrlich ist. Es genügt, die Buchblätter rückseitig mit einer Leimschicht miteinander zu verkleben. Auch läßt sich ein nur auf den Rücken beschränktes Fälzel verwenden.However, it should be expressly pointed out that such a
Anstelle eines Fälzels kann auch ein mit Vliesfasern durchsetzter Leim eingesetzt werden, der nach dem Aushärten eine ähnliche Funktion wie die Kombination Leim und Fälzel bewirkt.Instead of a felling, a glue interspersed with fleece fibers can be used, which after hardening has a similar function to the combination of glue and felling.
Am Deckelrücken 20 ist mittels einer Klebschicht 30 ein Verstärkungsstreifen 32 fest angeklebt, der z.B. aus einem Kartonstreifen besteht, dessen Breite derjenigen des Deckelrückens 20 im wesentlichen entspricht. Dieser Verstärkungsstreifen 32 weist an seiner freien Oberfläche eine Veredelung z.B. in Form einer Folienkaschierung 34 auf. Mit dieser Rückenverstärkung des Deckels 14 wird eine Stabilisierung erreicht, die beim Schneiden des Buches ein Ausfasern bwz. Ausreißen verhindert.A
Die Oberfläche der Veredelungsschicht 34 weist zusätzlich eine Haftklebeschicht 36 auf, die mit einer Haftmittelschicht 38 zusammenwirkt, welche sich an der freien Oberfläche des Rückens des Fälzels 22 befindet. Im geschlossenen Zustand des Buches 10 sind die beiden Haftmittelschichten 36, 38 miteinander fest verbunden, sodaß der Buchblock 12 am Deckelrücken 20 befestigt ist. Diese feste Verbindung erlaubt ein problemloses Schneiden des Buches, sodaß die Broschur eine exakt kantige Form aufweist, die auch bei Gebrauch erhalten bleibt, wobei im zugeschlagenen Zustand des Buches kein deutlich sichtbarer Spalt zwischen dem Buchblockrücken 12a und dem Deckelrücken 20 vorhanden ist. Öffnet man nun aber das Buch 10, so hebt sich der Buchblockrücken 12a zuerst in der Mitte vom Deckelrücken 20 ab, da dieser dank des Verstärkungsstreifens 32 extrem biegesteif ist. Die Spaltbildung erfolgt zwischen den beiden Haftmittelschichten 36, 38 und beim weiteren Aufschlagen wird der Buchblockrücken 12a vom Deckelrücken 20 vollständig gelöst und hebt sich von diesem ab. Beim anschließenden Zuschlagen des Buches gelangen die beiden Haftmittelschichten 36, 38 wieder in Kontakt und es tritt eine erneute Haftverbindung zwischen Buchblockrücken 12a und Deckelrücken 20 ein.The surface of the
Die Deckelblätter 16, 18 sind über sogenannte Vor- und Nachsätze mit dem ersten Blatt 26 bzw. dem letzten Blatt 28 des Buchblockes 12 verbunden. Der Vorsatz besteht aus einem Doppelbogen 40, 42, der in einem Abstand von der Blockrückenkante einen Falz 44 aufweist. Der Außenbogen 40 ist breitflächig mittels eines Klebestreifens 46 mit dem Deckel 16 verbunden, während der Innenbogen 42, ebenfalls breitflächig, mittels Klebstoffschicht 48 mit dem ersten Blatt 26 des Buchblockes 12 verbunden ist. Im Bereich dieses Falzes 44 weist das Deckelblatt 16 eine Faltrille 50 auf, sodaß beim Aufklappen des Buches der Deckel 16 um diese Faltrille 50 verschwenkt, dabei die Zugkraft auf den Außenbogen 40 des Vorsatzes überträgt. Am Falz 44 des Doppelbogens 40, 42 wird ein Gelenk gebildet. Das Aufklappen des Deckelblattes 16 übt praktisch keine Zugbeanspruchung auf das erste Blatt 26 des Buchblockes 12 aus. Eine Ausreißgefahr des ersten Blattes 26 bzw. letzten Blattes 28 vom Buchblockrücken ist also eliminiert.The
