Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Formen des Rückenbereiches und/oder der daran angrenzenden Falzbereiche von Buchdecken gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a device for shaping the back region and / or the adjoining fold regions of book covers according to the preamble of claim 1.

Zur maschinellen Herstellung von Büchern sind Buchfertigungsmaschinen bekannt, welche Vorrichtungen zum Transport und Vorrichtungen zur Bearbeitung der zugeführten Buchblöcke, Vorrichtungen zum Transport und Vorrichtungen zur Bearbeitung der zugeführten Buchdecken sowie Vorrichtungen zum Fügen jeweils eines Buchblockes mit einer zugeordneten Buchdecke, dem sog. Einhängen umfassen. Solche Buchfertigungsmaschinen sind derart gestaltet, dass sowohl die Buchblöcke, die Buchdecken als auch die Bücher stets symmetrisch zur Mittenebene der Buchblöcke, welche den Buchblock bei halber Blockdicke teilt, ausgerichtet sind. Vor dem Einhängen, werden die Buchdecken hinsichtlich der gewünschten Form des Buchrückens und der daran angrenzenden Falzbereiche vorgeformt. Dazu sind Vorrichtungen bekannt, welche den Rückenbereich der ausgestreckten Buchdecke gegen ein Paar die Falzbereiche der Buchdecke niederhaltenden Schienen ausheben. Diese Schienen sind als Niederhalteschienen flach gestaltet oder als Falzformschienen keilförmig mit gerundetem Formbereich und werden abhängig von der Breite des Buchrückens positioniert, wozu automatisierte Verstellantriebe vorgesehen sind. Das den Rückenbereich der Buchdecke aushebende Formstück entspricht in seiner Breite und Kontur dem Buchrücken.For machine production of books book making machines are known, which comprise devices for transport and devices for processing the supplied book blocks, devices for transport and devices for processing the supplied book covers and devices for joining a book block with an associated book cover, the so-called. Such book making machines are designed so that both the book blocks, the book covers and the books are always aligned symmetrically to the center plane of the book blocks, which divides the book block at half block thickness. Before hanging, the book covers are preformed with respect to the desired shape of the spine and adjoining seam areas. For this purpose, devices are known which lift the back region of the extended book cover against a pair of folding areas of the book cover down-holding rails. These rails are designed as hold-down rails flat or wedge-shaped as folded form rails with a rounded shape range and are positioned depending on the width of the spine, including automated adjustment drives are provided. The back of the book cover aushebende fitting corresponds in its width and contour of the spine.

Für das Vorformen von Buchdecken für Bücher mit geradem Rücken sind Formstücke bekannt, die sich im Wesentlichen aus einer Grundplatte und einem Paar paralleler entsprechend der Rückenbreite zueinander beabstandeter Schienen bestehen. Die Schienen sind in Langlöchern mit der Grundplatte verschraubt, so dass das Formstück der Breite des Buchrückens angepasst werden kann. Dazu wird aus Gründen der Zugänglichkeit das Formstück aus der Vorrichtung entnommen, die Schienen manuell an der gewünschten Position befestigt und das Formstück anschließend wieder in die Vorrichtung eingesetzt. Dies führt dazu, dass der Aufwand, die Vorrichtung auf die gewünschte Rückenbreite einzustellen, beträchtlich ist und für Korrekturen der Einstellung ein Maschinenstillstand und damit einhergehend eine Produktionsunterbrechung erforderlich sind.For the preforming of book covers for books with straight back moldings are known, which consist essentially of a base plate and a pair of parallel corresponding to the back width spaced rails. The rails are screwed in slots with the base plate, so that the fitting of the width of the book spine can be adjusted. For this purpose, the fitting is removed from the device for reasons of accessibility, the rails are fastened manually to the desired position and the fitting is subsequently inserted back into the device. As a result, the effort to set the device to the desired spine width is considerable, and adjustments to the adjustment require machine downtime and concomitant production stoppage.

Zur Vereinfachung dieser Einstellung des Formstückes für Bücher mit geradem Rücken schlägt EP 2 325 020 A1 einen Verstellmechanismus vor, welcher die beiden den Rückenbereich aushebenden Schienen durch Mitnehmer derart miteinander koppelt, dass sie zwangsweise parallel sowie symmetrisch zur o.g. Mittenebene der Buchblöcke verstellt werden. Soll der Buchblock nicht symmetrisch in die Buchdecke eingehängt werden, um später innerhalb des Buches weitere Elemente wie bspw. eine Verpackung für Compact Discs aus Kunststoff, sog. Jewelcases zu ergänzen, muss die Buchdecke zwischen dem Vorformen und dem Einhängen quer zur Transportrichtung verschoben werden. Aufgrund der Falzbereiche und der Vorformung ist die Buchdecke aber gerade in Richtung der Rückenbreite geschwächt, so dass das Verschieben quer zur Transportrichtung und damit in Richtung der Rückenbreite eine reduzierte Produktionsgeschwindigkeit erfordert und eine Quelle für Störungen und geminderte Produktionsqualität darstellt.To simplify this adjustment of the fitting for books with a straight back suggests EP 2 325 020 A1 an adjusting mechanism, which couples the two rails that lift out the back region by drivers in such a way that they are forcibly moved in parallel and symmetrically to the above-mentioned center plane of the book blocks. If the book block is not symmetrically hung in the book cover to later in the book other elements such as, for example, a package for plastic compact discs, so-called Jewelcases to complement the book cover must be moved between the preforming and hanging transversely to the transport direction. Due to the fold areas and the preforming the book cover is weakened but just in the direction of the spine width, so that moving transversely to the transport direction and thus in the direction of the spine width requires a reduced production speed and is a source of disturbances and reduced production quality.

Bei der Produktion von Büchern mit gerundetem Rücken sind Formstücke erforderlich, welche nicht nur in ihrer Breite sondern auch in der Krümmung ihrer der Buchdecke zugewandten Fläche der Form des herzustellenden Buches entsprechen. Die Menge der unterschiedlichen Rückenbreiten und Krümmungen führt zu einer Vielzahl erforderlicher Formstücke und entsprechendem Aufwand beim Rüsten. Um die Vielfalt an Formstücken reduzieren zu können wird häufig eine geringe Abweichung insbesondere in der Breite von der idealen Form toleriert und dadurch hervorgerufene Qualitätseinbußen hingenommen.In the production of books with rounded spine shaped pieces are required, which correspond not only in their width but also in the curvature of their book cover surface facing the shape of the book to be produced. The amount of different back widths and curvatures leads to a large number of required fittings and the corresponding effort when equipping. In order to reduce the variety of fittings is often tolerated a small deviation, in particular in the width of the ideal shape and thereby tolerated quality losses are accepted.

Die EP 1 350 634 B1 schlägt ein Formstück für die Herstellung von Büchern mit gerundetem Rücken vor, welches einen geschlossenen Rahmen und eine Vielzahl in diesem Rahmen höhenverstellbar angebrachter, nebeneinander stehender Lamellen umfasst. Die Lamellen weisen individuell geformte bogenförmige Langlöcher auf, derart dass das gesamte Lamellenpaket mit diesen Langlöchern auf Bolzen gefädelt ist, so dass durch Bewegung dieser Bolzen in Längsrichtung des Formstückes die Lamellen entsprechend der Bogenform der Langlöcher in ihrer Höhe unterschiedlich verstellt werden, so dass die Kontur des Formstückes unterschiedliche durch Stufenprofile angenäherte Radien abbilden kann. Die Güte der formenden Oberfläche wird dabei maßgeblich von der Materialstärke der Lamellen bestimmt. Nachteilig dabei sind der erforderliche Platzbedarf für den das Lamellenpaket umschließenden Rahmen sowie die erforderliche Fixierung der Lamellen nach dem Einstellvorgang durch zusätzliche Mittel. Außerdem kann ein solches Formstück bedingt durch die gekoppelte Verstellung der Lamellen jeweils nur eine Kontur in Abhängigkeit von der Rückenbreite erzeugen. Sollen bei gleicher Blockdicke unterschiedlich stark gekrümmte Buchrücken erzeugt werden, sind mehrere solcher Formstücke erforderlich, welche sich in dem Verlauf der Nuten in den Lamellen unterscheiden.The EP 1 350 634 B1 proposes a fitting for the production of books with a rounded back, which includes a closed frame and a plurality of height adjustable mounted in this context, side by side slats. The slats have individually shaped arcuate slots, so that the entire disc pack is threaded with these slots on bolts, so that the lamellae are moved differently in height by moving these bolts in the longitudinal direction of the fitting according to the arc shape of the slots, so that the contour of the fitting can represent different by step profiles approximated radii. The quality of the forming surface is largely determined by the thickness of the slats. The disadvantage here is the required space for the frame surrounding the plate package and the required fixation of the slats after the adjustment process by additional means. In addition, due to the coupled adjustment of the slats, such a shaped piece can only produce one contour depending on the back width. Should be different for the same block thickness strongly curved spines are generated, several such fittings are required, which differ in the course of the grooves in the slats.

An die vorliegende Erfindung stellt sich somit die Aufgabe, eine Vorrichtung einfacher Konstruktion zur Verfügung zu stellen, die es bei hohem Automatisierungsgrad ermöglicht, Buchdecken mit Rücken unterschiedlicher Geometrien vorzuformen.The object of the present invention is thus to provide a device of simple construction which, with a high degree of automation, makes it possible to preform book covers with backs of different geometries.

Erfindungsgemäß wird diese Aufgabe gelöst, indem die Vorrichtung zum Vorformen der Buchdecke im Rückenbereich und/oder den daran angrenzenden Falzbereichen ein Formstück vorsieht, welches ein Basiselement umfasst sowie ein oder mehrere zu diesem Basiselement und unabhängig zueinander verstellbare Formelemente, wobei jedem dieser Formelemente jeweils ein separater mit ihm verbundener Verstellantrieb zugeordnet ist. Der erzielte Vorteil liegt darin, dass auf einfache Weise ein einzelnes Formstück eine wesentlich größere Vielfalt erzeugbarer Rückengeometrien insbesondere hinsichtlich Rückenbreite, Asymmetrie und/oder Krümmung ermöglicht, als mit den bekannten Vorrichtungen, wobei die Verstellung motorisch und damit automatisiert erfolgt. Auf diese Weise lassen sich der für das Rüsten erforderliche Aufwand und die Anzahl erforderlicher Wechselteile deutlich reduzieren.According to the invention, this object is achieved by the device for preforming the book cover in the back region and / or the adjacent Falzbereichen a molding provides, which comprises a base member and one or more to this base member and independently adjustable mold elements, each of these mold elements each having a separate associated with it is associated adjusting drive. The advantage achieved is that in a simple way a single fitting allows a much greater variety of generated back geometries, especially in terms of back width, asymmetry and / or curvature, as with the known devices, the adjustment is motorized and thus automated. In this way, the effort required for the setup and the number of required replacement parts can be significantly reduced.

In einer vorzugsweisen Ausgestaltung der Erfindung umfasst das Formstück neben dem Basiselement zwei als verstellbare Formelemente sich in Rückenlängsrichtung erstreckende zueinander parallele den Rückenbereich der Buchdecke aushebende Schienen, welche in einer zur gestreckten Lage der Buchdecke parallelen Ebene im Wesentlichen senkrecht zur Längenorientierung der Schienen verstellbar gestaltet sind. So ist es bei Verzicht auf ein seitliches Versetzen der Buchdecken zwischen Deckenvorformen und Bucheinhängen möglich, sowohl symmetrisch als auch asymmetrisch eingehängte Bücher unterschiedlicher Rückenbreiten ohne manuelles Rüsten der Vorrichtung zum Deckenvorformen einer Buchfertigungsmaschine und insbesondere ohne Wechselteile zu erzeugen.In a preferred embodiment of the invention, the fitting comprises adjacent to the base member two adjustable longitudinally extending in the longitudinal direction parallel to the back portion of the book cover aushebende rails which are designed to be adjustable in a plane parallel to the stretched position of the book cover substantially perpendicular to the longitudinal orientation of the rails. Thus, in the absence of lateral displacement of the book covers between Deckenvorformen and book attachments is possible to produce both symmetrically and asymmetrically hinged books of different back widths without manual setup of the device for ceiling preforming a book production machine and in particular without change parts.

In einer zweiten bevorzugten Ausgestaltung der Erfindung umfasst das Formstück neben dem Basiselement wenigstens ein verstellbares Formelement, welches sich im Wesentlichen senkrecht zu der von der gestreckten Buchdecke festgelegten Ebene relativ zu dem Basiselement verstellen lässt. Auf diese Weise lässt sich die Hüllkurve des Formstückes automatisiert auf unterschiedliche Krümmungen der Buchdecke einstellen.In a second preferred embodiment of the invention, the shaped piece comprises, in addition to the base element, at least one adjustable form element which can be adjusted substantially perpendicular to the plane defined by the stretched book cover relative to the base element. In this way, the envelope of the fitting can be adjusted automatically to different curvatures of the book cover.

Entgegen der gängigen Lehre können Buchdecken mit gerundetem Rücken ohne Qualitätseinbuße erzeugt werden, wenn der Rückenbereich der Buchdecke während des Deckenvorformens nicht vollflächig auf dem Formstück aufliegt. In vorzugsweiser Ausgestaltung der zweiten Ausführungsform umfasst daher das Formstück Bereiche der während des Deckenvorformens von dem Rückenbereich der Buchdecke eingehüllten Oberfläche, welche während des Deckenvorformens zu dem Rückenbereich der Buchdecke beabstandet bleiben. Damit ist es mit einem einfach aufgebauten und aus wenigen Komponenten bestehenden Formstück möglich, sowohl die Breite als auch die Krümmung des Rückenbereiches unabhängig voneinander zu variieren, so dass beliebige gerundete Rückenbereiche ohne die Verwendung von Wechselteilen erzeugt werden können.Contrary to the common doctrine book cover with rounded back can be produced without loss of quality, if the back area of the book cover does not rest during blanket preforming over the entire surface of the fitting. In a preferred embodiment Therefore, according to the second embodiment, the molding comprises portions of the surface enveloped by the back portion of the book cover during blanket preforming, which remain spaced from the back portion of the book cover during blanket preforming. Thus, it is possible with a simply constructed and consisting of a few components fitting to vary both the width and the curvature of the back independently of each other, so that any rounded back areas can be generated without the use of removable parts.

Vorzugsweise ist jedes der Formelementes durch Hebel parallel verstellbar geführt. Diese einfache Ausführung in Art eines Viergelenkes ermöglicht eine kompakte und doch robuste Bauform.Preferably, each of the mold element is guided in parallel adjustable by lever. This simple design in the manner of a four-bar linkage allows a compact yet robust design.

In einer alternativen Ausgestaltung wird die Verstellung der Formelemente durch Kulissenführungen erreicht. Dies bietet den Vorteil, dass die Kulissen frei gestaltet werden können und so die Übertragungsfunktionen zwischen Verstellantrieb und Verstellweg jedes Formelementes optimiert werden können, etwa um in häufig genutzten Bereichen eine besonders genaue Verstellung zu erzeugen.In an alternative embodiment, the adjustment of the form elements is achieved by link guides. This offers the advantage that the scenes can be designed freely and so the transfer functions between adjustment and adjustment of each mold element can be optimized, for example, to produce a particularly accurate adjustment in frequently used areas.

In vorteilhafter Weise sind die Verstellantriebe für die Formelemente steuerbar und mit der Steuerung der Vorrichtung verbunden, sodass das Einstellen der Vorrichtung automatisiert anhand der Steuerung verfügbarer Produktdaten erfolgen kann. Weiterhin ist es vorteilhaft, die Verstellantriebe ortsfest auszuführen, da so die bewegte Masse reduziert und die elektrischen Leitungsverbindungen der Verstellantriebe weniger belastet werden und die elektrische Installation einfach gehalten werden kann.Advantageously, the adjusting drives for the mold elements are controllable and connected to the control of the device, so that the setting of the device can be done automatically based on the control of available product data. Furthermore, it is advantageous to perform the adjustment stationary, since so reduces the moving mass and the electrical wiring connections of the adjustment drives are less loaded and the electrical installation can be kept simple.

In weiterer vorteilhafter Gestaltung ist jedes der Formelemente jeweils mit dem ihm zugehörigen Verstellantrieb permanent antriebsverbunden. Auf diese Weise kann auch während der Bewegung des Formstückes, insbesondere beim Rückhub in die Ruhelage dieses bereits auf die zu formende Buchdecke eingestellt werden, was insbesondere bei der Fertigung von Kleinstauflagen von Bedeutung ist. Auch kann auf diese Weise das Fixieren der Formelemente durch den Verstellantrieb erfolgen, so dass hierfür keine weiteren Einrichtungen wie bspw. Klemmungen erforderlich sind und daher die Konstruktion einfach, platzsparend und leicht gehalten werden kann.In a further advantageous embodiment, each of the mold elements is permanently connected to drive in each case with the associated adjusting drive. In this way, even during the movement of the shaped piece, in particular during the return stroke in the rest position, this can already be set to the book cover to be formed, which is particularly important in the production of very small runs. Also can be done in this way the fixing of the mold elements by the adjustment, so that no further facilities such as. Clamps are required and therefore the construction can be kept simple, space saving and easy.

Um während der Bewegung des Formstückes den erforderlichen Ausgleich zwischen Formelement und dem jeweiligen Verstellantrieb zu erzeugen wird eine bei der Bewegung des Formstückes in einem Langloch laufende Rolle vorgeschlagen. Auf diese Weise ist eine hohe Präzision in der Übertragung der Bewegung bei geringem Verschleiß möglich.In order to produce the required balance between the form element and the respective adjustment drive during the movement of the fitting, a roller running in a slot during the movement of the fitting is proposed. In this way, a high precision in the transmission of movement with little wear is possible.

Die in Längsrichtung des Rückenbereiches 30 der Buchdecke 29 parallele Schienen 4.1 und 4.2 sind jeweils in Linearführungen 5 in Ausdehnungsrichtung der Rückenbreite verschieblich in dem Basiselement 3 gelagert, mit dem sie das Formstück 2.1 bilden. Die Vorrichtung 1 sieht für jede der beiden Schienen 4.1 und 4.2 jeweils eine Verstelleinheit vor, welche einen Verstellantrieb 10.1 bzw. 10.2 und eine über ein Winkelgetriebe 9 mit diesem Verstellantrieb 10.1. bzw. 10.2 antriebsverbundene Spindel 8 beinhaltet. Die Verstellantriebe 10.1 und 10.2 sind von der Aushubbewegung des Formstückes 2.1 unabhängig ortsfest angebracht, so dass die bei jedem Formvorgang bewegte Masse gering gehalten ist und sich eine einfache, mechanisch gering belastete elektrische Installation ergibt. Die Spindeln 8 verschieben in Deckentransportrichtung T jeweils ein in Aushubrichtung A orientiertes Langloch 6, in welchem eine Rolle 7 läuft, um einerseits die Verschiebung der Langloches 6 über weitere Glieder auf die Schiene 4.1 bzw. 4.2 zu übertragen und andererseits die Relativbewegung innerhalb der Verstelleinheit in Aushubrichtung A zu ermöglichen. Die Rollen 7 sind jeweils über weitere Glieder mit den in Figur 2 gezeigten Schubstangen 11.1 bzw. 11.2 verbunden, wobei es jeweils ein in einem nach oben offenen Schlitz angebrachter Stift erlaubt, das Formstück 2.1 auf einfache Weise nach oben aus der Vorrichtung 1 zu entnehmen, um es bspw. gegen ein in einem zweiten Ausführungsbeispiel beschriebenes Formstück 2.2 für runde Rücken zu tauschen.The parallel in the longitudinal direction of the back portion 30 of the book cover 29 rails 4.1 and 4.2 are each displaceable in linear guides 5 in the extension direction of the spine width stored in the base member 3, with which they form the fitting 2.1. The device 1 provides for each of the two rails 4.1 and 4.2 in each case an adjusting before, which is an adjustment 10.1 and 10.2 and one via an angle gear 9 with this adjustment 10.1. or 10.2 drive-connected spindle 8 includes. The adjusting drives 10.1 and 10.2 are independently fixed in place by the lifting movement of the shaped piece 2.1, so that the mass moved during each shaping operation is kept low and results in a simple, mechanically slightly loaded electrical installation. The spindles 8 move in the ceiling transport direction T each one in the lifting direction A oriented slot 6, in which a roller 7 runs, on the one hand to transfer the displacement of the elongated hole 6 via more links to the rail 4.1 and 4.2 and on the other hand, the relative movement within the adjustment in To allow excavation A direction. The rollers 7 are each over other links with the in FIG. 2 shown push rods 11.1 and 11.2 respectively, wherein it is in each case a mounted in an upwardly open slot pin allows to remove the fitting 2.1 in a simple manner upwards from the device 1, for example. Against a described in a second embodiment fitting 2.2 to swap for round backs.

Die Verstellantriebe 10.1 und 10.2 sind mit einer nicht dargestellten Steuerung der Buchfertigungsmaschine verbunden, derart dass eine automatisierte Verstellung anhand der Steuerung verfügbarer Produktionsparameter möglich ist.The adjusting drives 10.1 and 10.2 are connected to a control, not shown, of the book production machine, such that an automated adjustment based on the control of available production parameters is possible.

Innerhalb des Formstückes 2.1 wird die durch die Spindel 8 erzeugte längsgerichtete Verstellbewegung durch zwei Kulissenführungen 12.1 bzw. 12.2 je Schiene 4.1 und 4.2 in die gewünschte Verstellung der Schienen 4.1 und 4.2 quer dazu in Richtung der Breitenausdehnung des Rückenbereiches 30 der Buchdecke 29 gewandelt. Dazu ist jeder Schiene 4.1, 4.2 jeweils eine Schubstange 12.1 bzw. 12.2 zugeordnet, an denen Bolzen 13 angeordnet sind, die jeweils sowohl in parallel zu den Schienen 4.10 und 4.2 ausgerichteten Langlöchern des Basiselementes 3 als auch in dazu nicht parallelen Langlöchern der in Breitenrichtung verschieblichen Schlitten 24.1 bzw. 24.2 geführt sind. Die Kulissenführungen 12.1 und 12.2 sind vorzugsweise bogenförmig gestaltet, derart dass das Übersetzungsverhältnis sich über den Verstellweg ändert, so dass bspw. für schmale Rücken eine genauere Verstellung möglich ist als für breite Rücken. Alternativ zu den Kulissenführungen 12.1 und 12.2 können auch nicht dargestellte Umlenkhebel eingesetzt werden.Within the fitting 2.1, the longitudinal adjustment generated by the spindle 8 is converted by two slide guides 12.1 and 12.2 each rail 4.1 and 4.2 in the desired adjustment of the rails 4.1 and 4.2 transverse thereto in the direction of the width extension of the back portion 30 of the book cover 29. For this purpose, each rail 4.1, 4.2 each associated with a push rod 12.1 and 12.2, on which bolts 13 are arranged, each in both parallel to the rails 4.10 and 4.2 aligned slots of the base member 3 and in non-parallel slots of slidable in the width direction Carriage 24.1 and 24.2 are guided. The slide guides 12.1 and 12.2 are preferably designed arcuate, such that the transmission ratio changes over the adjustment, so that, for example, for narrow back a more accurate adjustment is possible as for wide back. As an alternative to the slotted guides 12.1 and 12.2 also reversing lever, not shown, can be used.

Eine alternativen Ausführung der Vorrichtung 1 umfasst anstelle des Formstückes 2.1 für die Herstellung von Büchern mit geradem Rücken ein in Figur 3 dargestelltes Formstück 2.2, mit dem der Rückenbereich 30 mit dem Ausheben aus der gestreckten Lage der Buchdecke 29 gerundet wird. Um unterschiedliche Formate und Konturen des Rückenbereiches 30 mit einem Werkzeug zu erzeugen, besteht das Formstück 2.2 aus mehreren ineinander verschachtelten Elementen, wobei das Basiselement 15 gleichzeitig zur Aufnahme des Formstückes 2.2 in der Vorrichtung 1 dient. In diesem Basiselement 15 ist ein erstes Formelement 16 verschieblich gelagert, derart dass das erste Formelement 16 gegenüber dem Basiselement 15 in Aushubrichtung A aus diesem angehoben werden kann. Dazu sind rampenförmige Führungen 18 oder Kulissen vorgesehen, welche aus dem Basiselement 15 und dem ersten Formelement 16 selbst gebildet sind, so dass eine relative Verschiebung des Basiselementes 15 und des ersten Formelementes 16 zueinander in Längsrichtung T ein Verschieben in Aushubrichtung A bewirkt. Auf gleiche Weise ist ein zweites Formelement 17 in dem ersten Formelement 16 gelagert, wodurch sich der in Figur 4 im Querschnitt gezeigte Aufbau ergibt und die Verstellung des Basiselementes 15 und der Formelemente 16 und 17 beliebig zueinander erfolgen kann. Zur Verstellung sind die Formelemente 16 und 17 über Koppelelemente 20 jeweils mit Schubelementen 19 bzw. 21 verbunden, welche in gleicher Weise wie die Schubstangen 11.1 und 11.2 des vorangehend beschriebenen Formstückes 2.1 von den Verstellantrieben 10.1 bzw. 10.2 betätigt werden. Jedes der formenden Elemente 15,16 und 17 zeigt in seinem Querschnitt im wesentlichen ein oder zwei Kreissegmente, wodurch sich abhängig von der gewählten Einstellung unterschiedliche Konturen der in Figur 4 gezeigten Art ergeben. Dabei weisen die Oberflächen der formgebenden Elemente 15, 16 und 17 Bereiche 22 auf, welche während des Formvorganges zu dem Rückenbereich 30 der Buchdecke 29 beabstandet bleiben. Die Wölbung der Buchdecke 29 oberhalb dieser kontaktfreien Bereiche 22 ergibt sich aus den Materialeigenschaften des Rückenbereiches 30 sowie der Spannungsverteilung innerhalb des Rückenbereiches 30, die es erlauben, den Rückenbereich 30 nicht vollflächig zu unterstützen.An alternative embodiment of the device 1 comprises instead of the shaped piece 2.1 for the production of books with a straight back in FIG. 3 illustrated fitting 2.2, with which the back portion 30 with the lifting of the extended position of Book cover 29 is rounded. In order to produce different formats and contours of the back region 30 with a tool, the shaped part 2.2 consists of several nested elements, the base element 15 simultaneously serving to receive the shaped part 2.2 in the device 1. In this base member 15, a first mold member 16 is slidably mounted, so that the first mold member 16 relative to the base member 15 in the lifting direction A can be raised from this. For this purpose, ramped guides 18 or scenes are provided, which are formed from the base member 15 and the first mold member 16 itself, so that a relative displacement of the base member 15 and the first mold member 16 to each other in the longitudinal direction T causes a displacement in the lifting direction A. In the same way, a second mold element 17 is mounted in the first mold element 16, whereby the in FIG. 4 shows structure shown in cross-section and the adjustment of the base member 15 and the mold elements 16 and 17 can be made arbitrarily to each other. To adjust the mold elements 16 and 17 are connected via coupling elements 20 each with thrust elements 19 and 21, which are operated in the same manner as the push rods 11.1 and 11.2 of the above-described fitting 2.1 of the adjusting drives 10.1 and 10.2. Each of the forming elements 15,16 and 17 shows in its cross section substantially one or two circle segments, whereby, depending on the selected setting different contours of in FIG. 4 shown type revealed. In this case, the surfaces of the shaping elements 15, 16 and 17 areas 22, which remain spaced apart during the molding process to the back portion 30 of the book cover 29. The curvature of the book cover 29 above these non-contact areas 22 results from the material properties of the back region 30 and the stress distribution within the back region 30, which do not allow the back region 30 to be supported over the entire surface.

Beide Formstücke 2.1 und 2.2 sind derart gestaltet, dass die Schnittstellen zu der Aufnahme in der Vorrichtung 1 identisch sind und die Formstücke 2.1 und 2.2 wechselweise in derselben Vorrichtung 1 eingesetzt werden können.Both fittings 2.1 and 2.2 are designed such that the interfaces to the receptacle in the device 1 are identical and the fittings 2.1 and 2.2 can be used alternately in the same device 1.
