Definitions
- the invention relates to an apparatus and method for bending wire binding elements used in wire comb binding.
- Wire-O TM wire binding elements registered trademark
- Methods for producing brochures using so-called Wire-O TM wire binding elements include, for example, US Pat European patent applications EP 0 095 243 A1 and EP 0 095 245 B1 known.
- Wire-O-wire binding elements are wire loops spaced parallel to one another and having a loop length L, a loop spacing A and a wire diameter D, as in FIG Fig. 2a represented, defined and formed by means of suitable closing devices to a wire O-ring.
- the binding devices for the aforementioned patent applications are designed such that the processing of preformed wire-O-wire binding elements with different loop spacings and lengths is made possible.
- the preformed wire-O-wire binding elements consist of wire loops, which, viewed from the side, each form two adjoining semicircles in a C- or ⁇ -shaped structure.
- the C- or ⁇ -shaped structure is closed after the sheet-shaped printing materials have been threaded with their holes in the wire binding element, so that there is a circular ring bond.
- the co-shaped structure arises when in the. Center of the loops of the wire binding element a bead was introduced. Such a bead may facilitate the closing operation of the preformed wire-O wire binding element.
- each wire loop of the wire comb must be bent into a ring. It should be noted that the radius of the resulting ring is dependent on the stack thickness of the sheet-like substrates and thus of the respective wire loop length.
- the C-formers on clamping flanks and noses, said lugs are equipped with a nose flank, said nose flank and clamping edge cooperate to clamp the loop-shaped wire binding element.
- the jamming of the loop-shaped wire binding element during C-forming is produced solely by the bending movement of the C-formers.
- the surface of the wire is spared.
- no additional moving parts are required, which would require a clamping of the wire binding element.
- the C-formers each have drives for a rotary movement, as well as drives for movement in the X-direction and Y-direction, as well as a controller for controlling the movement of the C-formers.
- the control is advantageously such that it controls the drives of the C-formers when bending the flat loop-shaped wire binding element in a C-shape, so that the pivot point the movement of the two C-formers lies within the loop-shaped wire binding element. It can thereby be achieved that the torque which clamps the wire binding element in bending while holding it in a fixed position, remains constant and no additional forces occur in the longitudinal direction with respect to the loop direction, which would lead to displacement of the loop within the deadlock. This prevents that the loop is not deformed when slipping and the wire is scratched.
- a flat, loop-shaped wire binding element can be bent in O-shape if the movement of the two C-formers during the bending process is synchronous with each other. As a result, additional lateral forces are avoided and the wire binding element in O-shape is rounder.
- the O-formers each have drives for a rotary movement, as well as drives for movement in the X-direction and Y-direction, as well as a controller for controlling the movement of the O-formers.
- the control of the drives of the O-Former in bending the flat loop-shaped wire binding element in an O-shape such that the fulcrum of the movement of the two O-former is within the loop-shaped wire binding element.
- the O-formers each have a drive for moving the O-formers in the Z-direction, as well as control means for controlling the movement in the Z-direction.
- the movement of the C or O-formers is designed such that the loop-shaped wire binding element is overbent by the C-formers and / or O-formers, so that the wire binding element relaxes upon release into the desired shape.
- the elastic portion of the wire must first be overcome to achieve permanent deformation of the wire. Also at a permanent deformation of the wire springs back the elastic region accordingly. In order to obtain a desired bending shape, therefore, must be bent beyond the desired shape, according to the expected springback.
- the O-formers are designed such that in each case individual bending elements are provided at least for each individual loop of the loop-shaped wire binding element, which are exchangeably fixed to the respective O-former.
- the number of bending elements per O-former is at least as large as the number of loops which are used for the loose binding of the largest format of sheet-shaped substrates to be processed. Since the O-formers are parts with relatively complex geometry, the division into individual, identically constructed bending elements can reduce the production outlay and thus the unit costs. Should individual flexures be damaged, e.g.
- all the bending elements may also be arranged on bars, each of the bars carrying a number of individual bending elements, e.g. 4 or 6. The bending elements are then barren in this embodiment are interchangeable attached to the respective O-former.
- Fig. 1 shows the overall structure of a device according to the invention, from the sake of simplicity of the description, only the components essential to the invention are shown or explained. Further, generally known and required for operating the device drive and / or guide means and electrical / electronic circuits are not shown or are described only in general terms.

- the O-formers 60, 60 'in the X-direction drive the correct point of engagement for the C-shape 41c to be produced.

- the O-formers 60, 60 ' subsequently release the jamming of the wire-binding element 41, now in C-shape 41c, drive the bending positions corresponding to the pivots P2, P2' and in turn clamp the wire-binding element 41 (see FIG Fig. 11-11 ).
- the position of the pivot points P2, P2 'in turn depends on the loop length L of the loops of the wire binding element and is predetermined by a controller (not shown).
- the parking position is selected such that the C-formers 50, 50 'are outside the range of motion of the O-formers 60, 60' in O-forming.
- the wire binding element 41 is bent over to the elastic Balancing spring back of the wire, so that the wire binding element 41 is in the tension-free state in the desired shape.

- the C-formers 50, 50 'and O-formers 60, 60' essentially not dependent on the loop length S, but limited only by the possibilities for movement on dedicated guides .
- the adaptation to the loop length L of the Drahtbindelements 41 is done via the position and movement curves of the C-former 50, 50 'and O-formers 60, 60'.
- a limitation of the loop length S downwards represents the size of the tabs 62, 62 'of the O-formers 60, 60', which must fit together with the spine within the O-shaped 41o closed wire binding element. Since the sheet-like substrates 11 in the booklet 10 but also in the bound state also still have to move, this represents technically practically no limitation to the format of a booklet 10 to be bound.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Biegen von Drahtbindeelementen, die in einer Drahtkammbindung Verwendung finden.The invention relates to an apparatus and method for bending wire binding elements used in wire comb binding.
Verfahren zur Herstellung von Broschüren, die sogenannte Wire-O™-Drahtbindeelemente (registrierte Handelsmarke) in verschiedenen Größen verwenden, sind beispielsweise aus den
Wire-O-Drahtbindeelemente sind als parallel zueinander beabstandete Drahtschlaufen mit einer Schlaufenlänge L, einem Schlaufenabstand A und einem Drahtdurchmesser D, wie in
Die Bindeeinrichtungen zu den vorgenannten Patentanmeldungen sind dabei derart ausgestaltet, dass die Verarbeitung vorgeformter Wire-O-Drahtbindeelemente mit verschiedenen Schlaufenabständen und -längen ermöglicht wird. Die vorgeformten Wire-O-Drahtbindeelemente bestehen dabei aus Drahtschlaufen, die von der Seite gesehen jeweils zwei aneinander anschließende Halbkreise in einer C- oder ω-förmigen Struktur bilden. Die C- oder ω-förmige Struktur wird geschlossen, nachdem die blattförmigen Bedruckstoffe mit ihren Löchern in das Drahtbindeelement eingefädelt wurden, so dass sich eine kreisförmige Ringbindung ergibt. Die co-förmige Struktur ergibt sich, wenn in der. Mitte der Schlaufen des Drahtbindeelements ein Sicke eingebracht wurde. Eine solche Sicke kann den Schließvorgang des vorgeformten Wire-O-Drahtbindeelements erleichtern.The binding devices for the aforementioned patent applications are designed such that the processing of preformed wire-O-wire binding elements with different loop spacings and lengths is made possible. The preformed wire-O-wire binding elements consist of wire loops, which, viewed from the side, each form two adjoining semicircles in a C- or ω-shaped structure. The C- or ω-shaped structure is closed after the sheet-shaped printing materials have been threaded with their holes in the wire binding element, so that there is a circular ring bond. The co-shaped structure arises when in the. Center of the loops of the wire binding element a bead was introduced. Such a bead may facilitate the closing operation of the preformed wire-O wire binding element.
Aus der
Generell besteht bei den genannten Vorrichtungen der Nachteil, dass zur Bindung von Broschüren unterschiedlicher Formate und Dicken die dafür notwendigen Drahtbindeelemente in Form mehrerer bereits geformter Bindeelementvorräte, z.B. als Rollenmaterial oder als auf Bindelänge geschnittene Elemente, der Bindeeinrichtung zur Verfügung gestellt werden müssen. Um diese unterschiedlichen Broschürenformate und - dicken binden zu können, ist bereits eine beachtliche Anzahl an Vorräten notwendig.In general, there is the disadvantage in the mentioned devices that for binding brochures of different formats and thicknesses the necessary wire binding elements in the form of a plurality of already formed binding element stocks, eg as roll material or cut to length elements, the binding device must be provided. In order to be able to bind these different brochure formats and thicknesses, a considerable number of inventories is already necessary.
Außerdem sind bei einem Formatwechsel der herzustellenden Broschüren die zum Transport und die zur Verarbeitung geeigneten Vorrichtungen an die Anforderungen der unterschiedlichen Drahtbindeelemente anzupassen. Diese Umrüstung erfordert aufwendige Konstruktionen der Transport- und Bindeeinrichtungen und macht das Bindeverfahren nur noch wirtschaftlich, wenn größere Stückzahlen einer Broschürendicke in einem Format hergestellt werden. Kleinere Auflagen sind daher unwirtschaftlich herzustellen und erfordern infolge der Maschinenanpassung einen längeren Zeitaufwand.In addition, when changing the format of the brochures to be manufactured, the devices suitable for transport and for processing must be adapted to the requirements of the different wire binding elements. This retrofitting requires complex constructions of the transport and binding devices and makes the binding process only economical if larger numbers of booklet thickness are produced in a format. Smaller editions are therefore uneconomical to produce and require due to the machine adaptation a longer time.
Aus der
Mit einer Vorrichtung zum Herstellen von Broschüren unterschiedlicher Formate und Dicken mittels Drahtkammbindung, mit der Drahtbindeelemente direkt im Bindeverfahren entsprechend ihres Bedarfs und des jeweiligen Formats und Dicke der zu bindenden Broschüren hergestellt werden können, muss jede Drahtschlaufe des Drahtkamms zu einem Ring zusammengebogen werden. Dabei ist zu beachten, dass der Radius des sich ergebenden Ringes von der Stapeldicke der blattförmigen Bedruckstoffe und damit von der jeweiligen Drahtschlaufenlänge abhängig ist.With a device for producing brochures of different formats and thicknesses by means of wire comb binding, with which wire binding elements can be produced directly in the binding process according to their needs and the respective format and thickness of the brochures to be bound, each wire loop of the wire comb must be bent into a ring. It should be noted that the radius of the resulting ring is dependent on the stack thickness of the sheet-like substrates and thus of the respective wire loop length.
Aus der nachveröffentlichten
Es ist die Aufgabe der Erfindung, ein Verfahren und eine Vorrichtung zum Biegen von Drahtbindeelementen zu schaffen, die an jeweils unterschiedliche Stapeldicken von Stapeln blattförmiger Bedruckstoffe ohne Umrüsten der Vorrichtung angepasst sind.It is the object of the invention to provide a method and a device for bending wire binding elements, which are adapted to different stacking thicknesses of stacks of sheet-like substrates without retooling the device.
Die Aufgabe wird mit einer Vorrichtung mit den Merkmalen gemäß Anspruch 1 sowie einem Verfahren gemäß Anspruch 6 gelöst. Weitere Merkmale ergeben sich aus den Unteransprüchen. Durch das Biegen des ebenen, schlaufenförmigen Drahtbindeelements in eine kontinuierlich kreisbogenartige C-Form kann ein besonders ästhetisches Aussehen des Drahtbindelements erzielt werden.The object is achieved with a device having the features according to
Vorteilhafterweise weisen die C-Former Klemmflanken und Nasen auf, wobei diese Nasen mit einer Nasenflanke ausgestattet sind, wobei Nasenflanke und Klemmflanke zusammenwirken, um das schlaufenformigen Drahtbindeelements zu klemmen. Dabei wird vorteilhafterweise die Verklemmung des schlaufenförmigen Drahtbindeelements beim C-Formen allein durch die Biegebewegung der C-Former erzeug. Dadurch wird unter anderem die Oberfläche des Drahtes geschont. Außerdem sind keine zusätzlichen beweglichen Teile erforderlich, die ein Klemmen des Drahtbindeelements erforderlich machen würden. Durch eine entsprechende Steuerung lassen sich unterschiedliche Schlaufenlänge biegen, ohne das eine Umrüstung an der Vorrichtung vorgenommen werden müssen.Advantageously, the C-formers on clamping flanks and noses, said lugs are equipped with a nose flank, said nose flank and clamping edge cooperate to clamp the loop-shaped wire binding element. In this case, advantageously, the jamming of the loop-shaped wire binding element during C-forming is produced solely by the bending movement of the C-formers. As a result, inter alia, the surface of the wire is spared. In addition, no additional moving parts are required, which would require a clamping of the wire binding element. By an appropriate control can bend different loop length without the need to make a conversion to the device.
Die C-Former weisen jeweils Antriebe für eine Drehbewegung, sowie Antriebe für Bewegung in X-Richtung und Y-Richtung auf, sowie eine Steuerung zur Ansteuerung der Bewegung der C-Former. Die Steuerung ist dabei vorteilhafterweise derart, dass sie die Antriebe der C-Former beim Biegen des ebenen schlaufenförmigen Drahtbindeelements in eine C-Form so steuert, so dass der Drehpunkt der Bewegung der beiden C-Former innerhalb des schlaufenförmigen Drahtbindeelements liegt. Dadurch kann erreicht werden, dass das Drehmoment, das das Drahtbindeelement beim Verbiegen verklemmt und dabei an einer fixen Position hält, konstant bleibt und keine zusätzlichen Kräfte in longitudinaler Richtung bezüglich der Schlaufenrichtung auftreten, die zum Verschieben der Schlaufe innerhalb der Verklemmung führen würden. Dadurch wird verhindert, dass die Schlaufe nicht beim Verrutschen deformiert wird und der Draht verkratzt wird.The C-formers each have drives for a rotary movement, as well as drives for movement in the X-direction and Y-direction, as well as a controller for controlling the movement of the C-formers. The control is advantageously such that it controls the drives of the C-formers when bending the flat loop-shaped wire binding element in a C-shape, so that the pivot point the movement of the two C-formers lies within the loop-shaped wire binding element. It can thereby be achieved that the torque which clamps the wire binding element in bending while holding it in a fixed position, remains constant and no additional forces occur in the longitudinal direction with respect to the loop direction, which would lead to displacement of the loop within the deadlock. This prevents that the loop is not deformed when slipping and the wire is scratched.
Besonders vorteilhaft kann ein ebenes, schlaufenförmiges Drahtbindeelement in O-Form gebogen werden, wenn die Bewegung der beiden C-Former während des Biegevorgangs synchron zueinander verläuft. Dadurch werden zusätzliche Querkräfte vermieden und das Drahtbindeelement in O-Form wird runder.Particularly advantageously, a flat, loop-shaped wire binding element can be bent in O-shape if the movement of the two C-formers during the bending process is synchronous with each other. As a result, additional lateral forces are avoided and the wire binding element in O-shape is rounder.
Vorteilhafterweise weisen die O-Former jeweils Antriebe für eine Drehbewegung, sowie Antriebe für Bewegung in X-Richtung und Y-Richtung auf, sowie eine Steuerung zur Ansteuerung der Bewegung der O-Former. Dabei ist die Steuerung der Antriebe der O-Former beim Biegen des ebenen schlaufenförmigen Drahtbindeelements in eine O-Form derart, dass der Drehpunkt der Bewegung des beiden O-Former innerhalb des schlaufenförmigen Drahtbindeelements liegt.Advantageously, the O-formers each have drives for a rotary movement, as well as drives for movement in the X-direction and Y-direction, as well as a controller for controlling the movement of the O-formers. In this case, the control of the drives of the O-Former in bending the flat loop-shaped wire binding element in an O-shape such that the fulcrum of the movement of the two O-former is within the loop-shaped wire binding element.
Zusätzlich weisen die O-Former jeweils einen Antrieb zur Bewegung der O-Former in Z-Richtung auf, sowie Steuerungsmittel zur Steuerung der Bewegung in Z-Richtung. Dadurch kann der oben beschriebene Vorgang des Eintauchens der Nasen des O-Formers in die Schlaufenebene automatisch durchgeführt werden.In addition, the O-formers each have a drive for moving the O-formers in the Z-direction, as well as control means for controlling the movement in the Z-direction. Thereby, the above-described operation of dipping the noses of the O-former in the loop plane can be automatically performed.
Vorteeilhafterweise ist die Bewegung der C- bzw. O-Former so gestaltet, dass das schlaufenförmige Drahtbindeelement durch die C-Former und/oder O-Former derart überbogen wird, so dass sich das Drahtbindeelement bei Entlastung in die gewünschte Form entspannt. Beim Drahtbiegen muss zunächst der elastische Bereich des Drahts überwunden werden, um eine permanente Verformung des Drahts zu erreichen. Auch bei einer permanenten Verformung federt der Draht dem elastischen Bereich entsprechend zurück. Um eine gewünschte Biegeform zu erhalten, muss daher über die gewünschte Form hinaus gebogen werden, entsprechend dem zu erwartenden Zurückfedern.Advantageously, the movement of the C or O-formers is designed such that the loop-shaped wire binding element is overbent by the C-formers and / or O-formers, so that the wire binding element relaxes upon release into the desired shape. When wire bending, the elastic portion of the wire must first be overcome to achieve permanent deformation of the wire. Also at a permanent deformation of the wire springs back the elastic region accordingly. In order to obtain a desired bending shape, therefore, must be bent beyond the desired shape, according to the expected springback.
In einer bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung sind die O-Former derart ausgestaltet, dass mindestens für jede einzelne Schlaufe des schlaufenförmigen Drahtbindeelements jeweils einzelne Biegeelemente vorgesehen sind, die an dem jeweiligen O-Former auswechselbar befestigt sind. Dabei ist die Anzahl der Biegeelemente pro O-Former mindestens so groß wie die Anzahl der Schlaufen die zum losen Binden des größten zu verarbeitenden Formats von blattförmigen Bedruckstoffen verwendet werden. Da es sich bei den O-Formern um Teile mit relativ komplexer Geometrie handelt, lässt sich durch die Aufteilung in einzelne, baugleiche Biegeelemente der Herstellungsaufwand und damit die Stückkosten reduzieren. Sollten einzelne Biegeelemente beschädigt werden, z.B. in dem die Nasen abbrechen, hat das zudem den Vorteil, dass hier nur die einzelnen Biegelemente ausgetauscht werden müssen, was die Kosten für den Werkzeugersatz erheblich reduziert. Alternativ können alle Biegelemente auch auf Barren angeordnet sein, wobei jeder der Barren eine Anzahl einzelner Biegeelemente trägt, z.B. 4 oder 6. Die Biegelemente sind dann barrenweise sind in dieser Ausführungsform auswechselbar an dem jeweiligen O-Former befestigt.In a preferred embodiment of the device according to the invention, the O-formers are designed such that in each case individual bending elements are provided at least for each individual loop of the loop-shaped wire binding element, which are exchangeably fixed to the respective O-former. In this case, the number of bending elements per O-former is at least as large as the number of loops which are used for the loose binding of the largest format of sheet-shaped substrates to be processed. Since the O-formers are parts with relatively complex geometry, the division into individual, identically constructed bending elements can reduce the production outlay and thus the unit costs. Should individual flexures be damaged, e.g. in which the noses break off, this also has the advantage that only the individual bending elements have to be exchanged here, which considerably reduces the costs for replacement of the tools. Alternatively, all the bending elements may also be arranged on bars, each of the bars carrying a number of individual bending elements, e.g. 4 or 6. The bending elements are then barren in this embodiment are interchangeable attached to the respective O-former.
Entsprechend eines weiteren Aspekts des erfindungsgemäßen Gedankens wird zur Lösung der Aufgabe ein Verfahren zum losen Binden von aus mit Löchern versehenen blattförmigen Bedruckstoffen zusammengesetzten Broschüren, mittels mindestens einem schlaufenförmigen Drahtbindeelement mit einer Vorrichtung gemäß Anspruch 1 offenbart, mit den Schritten:

- b) Biegen des ebenen, schlaufenförmigen Drahtbindeelements in eine kontinuierlich kreisbogenartige C-Form mit zwei C-Formern,
- c) Biegen des schlaufenförmigen Drahtbindeelements in C-Form in eine geschlossene O-Form mit zwei O-Formern.
- a) introduction of the initially flat, loop-shaped wire binding element through holes of the sheet-shaped substrates,
- b) bending the planar, loop-shaped wire binding element into a continuous circular arc-like C-shape with two C-formers,
- c) bending the loop-shaped wire binding element in C-shape into a closed O-shape with two O-formers.

Die erfindungsgemäße Vorrichtung besteht im Wesentlichen aus einem Paar C-Former 50, 50', die gemeinsam ein ebenes, schlaufenförmiges Drahtbindeelement 41 in eine vorläufige C-Form 41c biegen und aus einem Paar O-Formern, die das zur C-Form 41c gebogene schlaufenförmige Drahtbindeelement 41 in eine geschlossene O-Form 41o zur losen Bindung von blattförmigen Bedruckstoffen 11 zu Broschüren 10 biegen.The device according to the invention consists essentially of a pair of C-
Ein Stapel von blattförmigen Bedruckstoffen 11, die eine Mehrzahl an Löchern 12 aufweisen, die außenkantengleich übereinandergelegt einen im Wesentlichen gerade Durchgang für die Schlaufen S des ebenen Drahtbindeelements 41 bilden, ist in einer Zange 70 eingespannt. Die blattförmigen Bedruckstoffe könnten z.B. von der Zange 70 angeliefert werden, insbesondere, wenn die erfmdungsgemäße Vorrichtung zu einem übergeordneten System gehört. In einer anderen Ausführungsform ist die Zange 70 fester Bestandteil der erfindungsgemäßen Vorrichtung, insbesondere, wenn es sich bei der Ausführungsform um ein Tischgerät zum losen Binden von Broschüren 10 handelt.A stack of sheet-shaped
Die C-Former 50, 50' sind an jeweils einer Achse 51, 51' angebracht und werden derart angetrieben, geführt und gesteuert, dass sie eine Drehbewegung um die jeweilige Achse 51, 51' ausführen können, wie durch die entsprechenden Pfeile in
Die O-Former 60, 60' weisen ebenfalls entsprechende, nicht gezeigte, dem Fachmann bekannte Antriebe, Führungseinrichtungen und Steuerungsmittel für Drehbewegungen um die jeweilige Achse 61, 61' sowie entlang der X- bzw. Y-Richtung. Darüber hinaus sind Antriebe, Führungs- und Steuerungsmittel für die O-Former 60, 60' vorgesehen, mittels der sich die O-Former 60, 60' in Z-Richtung bewegen lassen. Die hier verwendeten kartesischen Koordinaten sind in dem Koordinatenkreuz in
Die C-Former 50, 50' weisen eine Geometrie auf, die ein Zentrieren und ein Greifen des schlaufenförmigen Drahtbindeelements 41 erlauben. Hierfür sind Nasen 52 zum Greifen, bzw. Verklemmen des schlaufenförmigen Drahtbindeelements 41 vorgesehen sowie Zentrierungselemente 53, 53' und Zentrierungstrichter 54, 54'.The C-
Die O-Former 60, 60' weisen ebenfalls Nasen 62, 62' auf, die zur Klemmung und zur Biegung des schlaufenförmigen Drahtbindeelements 41 in C-Form 41c dienen, die im Folgenden näher beschrieben werden.The O-
Die C-Former 50, 50' untereinander respektive O-Former 60, 60' untereinander unterscheiden sich vom Aufbau außer der Spiegelsymmetrie nicht wesentlich, allerdings werden im weiteren, insbesondere zur Beschreibung des erfindungsgemäßen Verfahrens von einem ersten C-Former 50 und einem zweiten C-Former 50' sowie von einem ersten O-Former 60 und einem zweiten O-Former 60' gesprochen. Dabei sind die ersten C-Former 50, bzw. ersten O-Former 60 jeweils dadurch gekennzeichnet, dass sie auf der Seite der blattförmigen Bedruckstoffe 11 angeordnet sind, auf der die Basisseite 41k des schlaufenförmigen Drahtbindeelements 41 liegt. Dadurch ergibt sich, dass die zweiten C-Former 50', bzw. zweiten O-Former 60' jeweils dadurch gekennzeichnet sind, dass sie auf der Seite der blattförmigen Bedruckstoffe 11 angeordnet sind, auf der die Spitzen 41s der Schlaufen S des schlaufenförmigen Drahtbindeelements 41 liegen.The C-

Die Länge der Nasen 62, 62' ist an die Schlaufenform des Drahtbindeelements 41 angepasst. Einerseits sind die Nasen 62, 62' auf der Innenseite länger als die Breite der Schlaufen S, so dass jeweils eine Schlaufe S mit einer Nase 62, 62' sicher erfasst werden kann. Andererseits sind die Nasen 62, 62' in ihrer Gesamtlänge kürzer als der Abstand zwischen zwei Schlaufen S.The length of the
Wie oben beschrieben sind die O-Former 60, 60' mit einem zusätzlichen Antrieb in Z-Richtung ausgestattet. Durch eine Kombination einer Bewegung in Y- und in Z-Richtung der O-Former 60, 60' tauchen die Nasen 62, 62' zunächst zwischen den Schlaufen S eines in die erfindungsgemäße Vorrichtung eingelegten Drahtbindeelements 41 auf und bewegen sich dann in Z-Richtung über die Schlaufen, um sie dann ähnlich der oben beschriebenen Bewegung der C-Former 50, 50' durch Verdrehung der O-Former 60, 60' zu klemmen und zu verbiegen.As described above, the O-

Im Anschluss fahren die O-Former 60, 60' in X-Richtung den richtigen Eingriffspunkt für die zu fertigende C-Form 41c an. Diese zu fertigende C-Form 41c hängt insbesondere von der Schlaufenlänge S ab, und damit wiederum von dem Durchmesser der fertigen O-Form und damit von der Dicke der zu bindenden Broschüre 10 ab. Im Anschluss bewegen sich die O-Former 60, 60' in Z-Richtung mit ihren Nasen 62, 62' über die Schlaufen S, bis die Nasen 62, 62' die Schlaufen S der Breite nach überdecken.Subsequently, the O-

Wie aus der Beschreibung des Verfahrens und der Bewegungsabläufe hervorgeht, sind die C-Former 50, 50' bzw. O-Former 60, 60' im Wesentlichen nicht von der Schlaufenlänge S abhängig, sondern nur durch die Möglichkeiten zur Bewegung auf dafür vorgesehenen Führungen beschränkt. Die Anpassung an die Schlaufenlänge L des Drahtbindelements 41 geschieht über die Position und Bewegungskurven der C-Former 50, 50' bzw. O-Former 60, 60'. Eine Beschränkung der Schlaufenlänge S nach unten stellt die Größe der Nasen 62, 62' der O-Former 60, 60' dar, die innerhalb des in O-Form 41o geschlossenen Drahtbindeelements zusammen mit dem Buchrücken Platz haben müssen. Da sich die blattförmigen Bedruckstoffe 11 in der Broschüre 10 aber im gebundenen Zustand ebenfalls noch bewegen müssen, stellt dies technisch praktisch keine Beschränkung für das Format einer zu bindenden Broschüre 10 dar.As can be seen from the description of the method and the movements, the C-
