Abstract

Stacks of sheets (50) to make up a book or folder are presented with their edges in alignment and their perforations (52) form straight bores through the stack near one edge. The alignment system changes the straight bores into curved bores ready for insertion of a ring binder. The pins (16a,b) are pushed toward each other in the bores in a straight line until their tips overlap. The pins are mounted on support blocks (56a,b) on lever arms (14a,b) which are pivoted together on hinges (12a,b). As the pins are withdrawn by pivoting the arms about their hinges, they realign the stack so that the perforations form curved bores which fit the ring binder.

Ein solches Verfahren und eine solche Vorrichtung werden gewöhnlich dazu verwendet, Papierblöcke oder sogenannte Nutzen, bestehend aus einer Vielzahl von übereinanderliegenden Papierbögen, so auszurichten, dass die Papierbögen mit ihren Perforationen, die zuvor entlang eines ihrer Randabschnitte eingebracht worden sind, übereinanderliegen. Diese Maßnahme dient der Vorbereitung, um anschließend in die Perforationen ein gekrümmtes Verbindungsmittel, insbesondere eine Drahtwendel, zur Bindung des Papierblockes oder Nutzens einzubringen bzw. einzudrehen.Such a method and apparatus are commonly used to make paper blocks or so-called benefits, consisting of a Variety of superimposed sheets of paper to align so that the paper sheets with their perforations, which have been previously introduced along one of its edge portions, superimposed. This measure serves for the preparation in order subsequently to introduce or to screw into the perforations a curved connection means, in particular a wire helix, for binding the paper block or utility.

Das Verfahren und die Vorrichtung der eingangs genannten Art bilden einen Teil einer halb- oder vollautomatisch arbeitenden Anlage zur Herstellung von Nutzen oder Papierblöcken, die beispielsweise mittels Drahtwendeln zusammengehalten sind. In derartigen Anlagen werden aus einer Papierbahn Papierbögen durch Schneiden hergestellt, wobei während dieses Arbeitsschrittes die Papierbögen gleichzeitig in einem Randabschnitt mit Hilfe einer Stanzvorrichtung perforiert und gegebenenfalls in einem Druckwerk bedruckt werden. Diese Papierbögen werden überlappt und zu Blöcken mit einer definierten Anzahl von Papierbögen gestapelt. Anschließend werden in einer Ausrichtvorrichtung der eingangs genannten Art die perforierten Randabschnitte zueinander ausgerichtet. Letzteres ist wichtig, um zum Binden der Papierblöcke in einer nachfolgenden Bindevorrichtung das gekrümmte Verbindungsmittel wie insbesondere eine Drahtwendel durch die Perforationen sämtlicher Papierbögen hindurch einbringen zu können.The method and the device of the type mentioned form part of a semi-automatic or fully automatic plant for the production of useful or paper blocks, which are held together, for example by wire helices. In such systems, paper sheets are produced by cutting from a paper web, wherein during this step, the paper sheets are perforated simultaneously in an edge portion by means of a punching device and optionally printed in a printing unit. These sheets of paper are overlapped and stacked into blocks with a defined number of sheets of paper. Subsequently, the perforated edge portions are aligned with each other in an alignment of the type mentioned. The latter is important to be able to bring the curved connecting means such as in particular a wire helix through the perforations of all paper sheets for binding the paper blocks in a subsequent binding device.

In der DE 2 653 759 A1 und DE 2 804 180 A1 ist jeweils ein Verfahren und eine Vorrichtung zum Ausrichten eines Blockes aus jeweils mit einer Lochreihe versehenen Papierbögen für das nachfolgende Eindrehen einer die Bögen zusammenhaltenden Drahtwendel offenbart. Die bekannte Vorrichtung weist zwei einander gegenüber angeordnete Dornreihen sowie Antriebsmittel zum Bewegen der Dornreihen aufeinander zu und voneinander weg auf. Mit Hilfe der Antriebsmittel werden die Dornreihen in die Lochreihen der übereinandergestapelten Papierbögen eingefahren und danach einer Schwenkbewegung unterworfen, wodurch die Papierbögen derart verschoben werden, dass die übereinanderliegenden Löcher ein "V" bilden. Hierzu werden also die beiden einander gegenüberliegenden Dornreihen, während sie in den Lochreihen der Papierbögen stecken, in eine V-förmige Anordnung verschwenkt. Nach Beendigung des V-förmigen Ausrichtens werden die Dornreihen aus den Lochreihen wieder herausgezogen, so dass diese nun für das nachfolgende Einbringen eines gekrümmten Verbindungsmittels, insbesondere einer Drahtwendel, frei und entsprechend vorbereitet sind.In the DE 2 653 759 A1 and DE 2 804 180 A1 In each case, a method and an apparatus for aligning a block of each provided with a row of holes paper sheets for the subsequent insertion of a wire holding the sheets together is disclosed. The known device has two oppositely arranged rows of mandrels and drive means for moving the rows of mandrels toward and away from each other. With the aid of the drive means, the rows of mandrels are moved into the rows of the stacked paper sheets and then subjected to a pivoting movement, whereby the paper sheets are moved so that the superimposed holes form a "V". For this purpose, so the two opposing rows of mandrels, while stuck in the rows of holes of the paper sheets, pivoted in a V-shaped arrangement. After completion of the V-shaped alignment, the rows of mandrels from the Hole rows pulled out again, so that they are now prepared for the subsequent introduction of a curved connection means, in particular a wire coil, free and appropriate.

Zur Erzeugung gekrümmter Lochungen eines Blattstapels verwendet die DE-A-1817815 krumme Dorne die die Lochungen bereits beim Einführen formen, während in der DE-A 2952183 ein entsprechend gekrümmter Formkörper an den Rücken des Blattstapels gedrückt wird und danach die geraden Dorne geradlinig aus den Lochungen herausgezogen werden.Used to create curved holes in a sheet stack DE-A-1817815 crooked spines that form the holes already during insertion, while in the DE-A 2952183 a correspondingly curved shaped body is pressed against the back of the sheet stack and then the straight mandrels are pulled straight out of the perforations.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, zum einen die Anzahl der Arbeitsschritte zu verringern und zum anderen die Genauigkeit der Ausrichtung des Stapels zu erhöhen, um das nachfolgende Einbringen eines gekrümmten Verbindungsmittels noch einfacher und reibungsloser gestalten zu können.The object of the present invention is firstly to reduce the number of work steps and secondly to increase the accuracy of the alignment of the stack in order to be able to make the subsequent introduction of a curved connecting means even easier and smoother.

Ferner wird die Aufgabe gemäß seinem zweiten Aspekt der vorliegenden Erfindung gelöst durch eine Vorrichtung gemäß Anspruch 6.Furthermore, the object according to its second aspect of the present invention is achieved by a device according to claim 6.

Die Erfindung ermöglicht eine Reduzierung der Arbeitsschritte. Dies wird erfindungsgemäß dadurch erreicht, dass die Schwenkbewegung zum Ausrichten des Stapels und das Entfernen des bzw. der Ausrichtetemente aus den Perforationen gleichzeitig und somit in einem und demselben Arbeitsschritt stattfindet. Auf diese Weise wird der Ausrichtvorgang erheblich verkürzt, was sich vorteilhaft auf die Prözessgeschwihdigkeit der gesamten Anlage auswirkt.The invention enables a reduction of the work steps. This is inventively achieved in that the pivoting movement for aligning the stack and the removal of the or the Ausrichtenemente from the perforations simultaneously and thus takes place in one and the same step. In this way, the alignment process is considerably shortened, which has an advantageous effect on the Prözessgeschwihdigkeit the entire system.

Eine weitere wichtig Maßnahme der Erfindung besteht darin, dass während der Schwenkbewegung das oder die Ausrichtelemente eine Bahn beschreiben, die im Wesentlichen dem Verlauf der Krümmung des Verbindungsmittels nachempfunden ist. Somit lässt sich der Stapel nicht nur näherungsweise - wie beispielsweise im vorgenannten Stand der Technik V-förmig - sondern im Wesentlichen exakt im Hinblick auf den vorgegebenen Krümmungsverlauf des verwendeten Verbindungsmittels ausrichten. Dadurch wird gewährleistet, dass sich im nachfolgenden Arbeitsschritt das gekrümmte Verbindungsmittel ohne jegliche Komplikationen sauber und einfach einbringen lässt, wodurch die Betriebssicherheit des gesamten Ablaufes deutlich erhöht wird.Another important measure of the invention is that, during the pivoting movement, the alignment element or elements describe a path which essentially follows the course of the curvature of the connection means. Thus, the stack is not only approximately - as in the aforementioned prior art, V-shaped - but align substantially exactly with regard to the predetermined curvature of the connecting means used. This ensures that in the subsequent step, the curved connecting means can be introduced cleanly and easily without any complications, whereby the reliability of the entire process is significantly increased.

Im Regelfall werden Verbindungsmittel mit einer teil- oder vollzylindrischen Form wie insbesondere Drahtwendeln verwendet. In einem solchen Fall sollte gemäß einer gegenwärtig besonders bevorzugten Ausführung der Erfindung während der Schwenkbewegung das mindestens eine Ausrichtelement oder die mindestens eine Reihe von Ausrichtelementen um eine erste Schwenkachse verschwenkt werden, die im Wesentlichen mit der Zylinderachse des einzubringenden Verbindungsmittels zusammenfällt oder in geringem Abstand parallel zu dieser verläuft. Hierzu weist vorzugsweise eine mit dem oder den Ausrichtelementen gekoppelte Bewegungseinrichtung mindestens ein Schwenkelement auf, das um die erste Schwenkachse verschwenkbar ist und an dem das mindestens eine Ausrichtelement oder die mindestens eine Reihe von Ausrichtelementen so befestigt ist, dass zumindest die Spitze des dorn- oder stiftförmigen Ausrichtelementes im Wesentlichen tangential in Bezug auf die erste Schwenkachse ausgerichtet und dabei in einem radialen Abstand zur ersten Schwenkachse angeordnet ist.As a rule, connecting means with a partially or fully cylindrical shape, in particular wire coils, are used.

As a result, the perforations of the stack can advantageously be aligned correspondingly in adaptation to a pitch of the curved connecting means to be introduced, which is particularly advantageous in the use of wire helices.

Ferner kann vor oder mit dem Schritt, mindestens ein Ausrichtelement oder die mindestens eine Reihe von Ausrichtelementen in die Perforationen einzufahren, der Stapel mit der Stirnseite seines mit den Perforationen versehenen Randabschnittes in Anlage ah eine Anlagefläche eines Stützelementes gebracht werden, wobei die Form der Anlagefläche des Stützelementes so gewählt ist, dass die übereinanderliegenden Perforationen entsprechend der Krümmung des Verbindungsmittels ausgerichtet werden, wenn sämtliche Flachteile des Stapels in Anlage an das Stützelement gebracht sind. Bei der Verwendung von Verbindungsmitteln mit einer teil- oder vollzylindrischen Form sollte vorzugsweise die Anlagefläche des Stützelementes eine teilzylindrische Form aufweisen, dessen Zylinderachse im Wesentlichen mit der ersten Schwenkachse zusammenfällt oder in einem geringen Abstand parallel zu dieser verläuft. Das Stützelement unterstützt zum einen nach Art einer Lehre die Ausrichtung der Perforationen in im Wesentlichen exakter Anpassung an den Verlauf der Krümmung des Verbindungsmittels während der Schwenkbewegung beim Herausziehen des oder der Ausrichtelemente und gewährleistet zum anderen, dass nach Entfernen des oder der Ausrichtelemente und insbesondere während des nachfolgenden Einbringens des Verbindungsmittels der Stapel in seiner entsprechend ausgerichteten Form verbleibt.Furthermore, prior to or with the step of retracting at least one alignment element or the at least one row of alignment elements in the perforations, the stack with the end face of its provided with the perforations edge portion in abutment ah a contact surface of a support element are brought, the shape of the contact surface of the Supporting element is selected so that the superimposed perforations are aligned according to the curvature of the connecting means when all flat parts of the stack are brought into contact with the support element. When using connecting means with a partially or fully cylindrical shape, the contact surface of the support element should preferably have a part-cylindrical shape, the cylinder axis coincides substantially with the first pivot axis or at a small distance parallel to this. The support element supports on the one hand in the manner of a doctrine the alignment of the perforations in substantially exact adaptation to the course of curvature of the connecting means during the pivoting movement when pulling out of the alignment elements and ensures on the other hand that after removal of the or the alignment and in particular during the subsequent introduction of the connecting means of the stack remains in its correspondingly aligned form.

Ein Verfahren zum Ausrichten von Nutzen wird zweckmäßiger Weise auf einer Vorrichtung 2 durchgeführt, wie sie in den beiliegenden Figuren beispielhaft dargestellt ist.A method of aligning benefits is conveniently performed on a device 2, as exemplified in the accompanying figures.

Die dargestellte Vorrichtung 2 weist zwei Supports 4a, 4b auf. Jeder der beiden Supports 4a, 4b weist ein Sockelelement 6a bzw. 6b auf, mit dem die Supports 4a, 4b auf einer gemeinsamen Achse 8 in etwa horizontaler Richtung verschieblich gelagert sind. Die Achse 8 sitzt auf einem in den Figuren nicht dargestellten Gerüst. Wie Fig. 1 erkennen lässt, besitzen beide Supports 4a, 4b im dargestellten Ausführungsbeispiel den gleichen Aufbau, sind jedoch spiegelsymmetrisch zueinander angeordnet.The illustrated device 2 has two supports 4a, 4b. Each of the two supports 4a, 4b has a base element 6a or 6b, with which the supports 4a, 4b are mounted displaceably on a common axis 8 in an approximately horizontal direction. The axis 8 is seated on a scaffold, not shown in the figures. As Fig. 1 can recognize, have both supports 4a, 4b in the illustrated embodiment, the same structure, but are arranged mirror-symmetrically to each other.

Im dargestellten Ausführungsbeispiel hat das Sockelelement 6a bzw. 6b eine V-Form mit einem auf den gegenüberliegenden Support schräg nach innen gerichteten ersten Schenkel 10a bzw. 10b und einem schräg nach außen gerichteten zweiten Schenkel 11a bzw. 11b. Am Ende des ersten Schenkels 10a bzw. 10b sitzt ein erstes Scharnier 12a bzw. 12b, dessen Scharnierachse im dargestellten Ausführungsbeispiel rechtwinklig zur Achse 8, aber ebenfalls horizontal ausgerichtet ist. Am ersten Scharnier 12a bzw. 12b ist ein erster Hebel 14a bzw. 14b angelenkt, an dessen freiem Ende mindestens ein gerader Dorn 16a bzw. 16b befestigt ist, dessen freie Spitze 17a bzw. 17b benachbart zum ersten Scharnier 12a bzw. 12b angeordnet ist, und zwar in einem radialen Abstandsmaß R, das zwischen der Scharnierachse des ersten Scharniers 12a bzw. 12b und der Mittelachse des Dornes 16a bzw. 16b definiert ist.In the illustrated embodiment, the base member 6a and 6b, respectively, has a V-shape with a first leg 10a, 10b directed obliquely inwardly toward the opposite support, and a second leg 11a, 11b directed obliquely outward. At the end of the first leg 10a and 10b sits a first hinge 12a and 12b, the hinge axis in the illustrated embodiment is at right angles to the axis 8, but also aligned horizontally. At the first hinge 12a and 12b, a first lever 14a and 14b articulated at the free end of at least one straight mandrel 16a and 16b is fixed, the free tip 17a and 17b adjacent to the first hinge 12a and 12b is arranged in a radial distance R defined between the hinge axis of the first hinge 12a and 12b and the center axis of the mandrel 16a and 16b, respectively.

Am freien Ende des schräg nach außen gerichteten zweiten Schenkels 11a bzw. 11b sitzt ein zweites Scharnier 20a bzw. 20b, dessen Scharnierachse parallel zur Scharnierachse des ersten Scharniers 12a bzw. 12b verläuft. An diesem zweiten Scharnier 20a bzw. 20b ist ein zweiter Hebel 22a bzw. 22b angelenkt, in dessen freies Ende ein in Längsrichtung offenes Langloch 24a bzw. 24b ausgebildet ist. In diesem Langloch 24a bzw. 24b sitzt eine Führungsrolle 26a bzw. 26b, deren Drehachse parallel zu den Scharnierachsen der ersten und zweiten Scharniere 12a bzw. 12b und 20a bzw. 20b verläuft und am freien Ende des ersten Hebels 14a bzw. 14b etwa in dem Bereich gelagert ist, wo der Dorn 16a bzw. 16b befestigt ist.At the free end of the obliquely outwardly directed second leg 11a and 11b sits a second hinge 20a and 20b, the hinge axis is parallel to the hinge axis of the first hinge 12a and 12b. At this second hinge 20a and 20b, a second lever 22a and 22b articulated, in the free end of a longitudinally open slot 24a and 24b is formed. In this slot 24a and 24b sits a leadership role 26a and 26b, whose axis of rotation is parallel to the hinge axes of the first and second hinges 12a and 12b and 20a and 20b and is mounted at the free end of the first lever 14a and 14b approximately in the area where the mandrel 16a or 16b is attached.

Die zweiten Hebel 22a, 22b werden von einer nicht dargestellten Antriebseinrichtung verschwenkt und nehmen dabei die ersten Hebel 14a, 14b mit, wodurch die Dorne 16a, 16b einer Schwenkbewegung unterworfen werden, und zwar zwischen einer horizontalen Stellung, in der die einander gegenüberliegende Dorne 16a, 16b mit ihren Spitzen 17a, 17b aufeinander zeigen und im Wesentlichen auf einer gemeinsamen Achse liegen, und einer nach unten zurückgeschwenkten Stellung, in der die Dorne 16a, 16b in einem größeren Abstand voneinander angeordnet sind und mit' ihrem Spitzen 17a, 17b schräg nach oben zeigen. In Fig. 1 sind die beiden einander gegenüberliegenden Dorne 16a, 16b in beiden Stellungen gestrichelt dargestellt.The second levers 22a, 22b are pivoted by a drive means, not shown, and thereby take the first lever 14a, 14b, whereby the mandrels 16a, 16b are subjected to a pivoting movement, between a horizontal position, in which the opposing mandrels 16a, 16b point with their tips 17a, 17b on each other and lie substantially on a common axis, and a downwardly pivoted position in which the mandrels 16a, 16b are arranged at a greater distance from each other and with 'their tips 17a, 17b obliquely upward demonstrate. In Fig. 1 are the two opposing mandrels 16a, 16b shown in dashed lines in both positions.

Auch wenn in den Figuren nur jeweils ein Paar von gegenüberliegenden Dornen 16a, 16b dargestellt ist, sind tatsächlich zwei gegenüberliegende Reihen von Dornen vorgesehen, die in einer Ebene nebeneinander liegen, die senkrecht zur Bildebene von Fig. 1 verläuft. Dabei sind die Abstände zwischen den einzelnen Dornen in jeder der beiden Reihen konstant.Although only a pair of opposed mandrels 16a, 16b are shown in the figures, there are actually provided two opposing rows of mandrels juxtaposed in a plane perpendicular to the image plane of FIG Fig. 1 runs. The distances between the individual spikes in each of the two rows are constant.

Wie Fig. 2 erkennen lässt, ist zwischen den beiden Supports 4a, 4b eine Stütze 30 (von der in Fig. 1 aus Gründen der besseren Übersichtlichkeit nur der Fuß dargestellt ist) angeordnet, die auf der Höhe der ersten Scharniere 12a, 12b in einem pilzförmigen Kopf 32 endet, dessen Oberfläche 33 gekrümmt ist.As Fig. 2 can be seen, between the two supports 4a, 4b, a support 30 (of the in Fig. 1 for the sake of clarity, only the foot is shown), which ends at the height of the first hinges 12a, 12b in a mushroom-shaped head 32 whose surface 33 is curved.

In Fig. 1 ist die Vorrichtung 2 im geöffneten Zustand dargestellt, in der die beiden Supports 4a, 4b mit Hilfe einer nicht näher dargestellten Antriebseinrichtung entlang der Achse 8 in ihren äußeren Endstellungen verfahren sind, wo sie einen maximalen Abstand voneinander einnehmen.In Fig. 1 the device 2 is shown in the open state, in which the two supports 4a, 4b are moved by means of a non-illustrated drive means along the axis 8 in their outer end positions, where they occupy a maximum distance from each other.

Demgegenüber ist in Fig. 2 die Vorrichtung 2 in ihrer (geschlossenen) Betriebsstellung gezeigt; in der die beiden Supports mit ihren Sockelelementen 6a, 6b entlang der Achse 8 so aufeinanderzu verfahren sind, dass die ersten Scharniere 12a, 12b mit ihren Scharnierachsen koaxial zueinander ausgerichtet sind. Damit die ersten Schenkel 10a, 10b der Sockelelemente 6a, 6b nicht miteinander kollidieren, sind diese ein wenig versetzt zueinander angeordnet. Das gleiche gilt auch für die Stütze 30. Wie Fig. 2 ferner erkennen lässt, ist die Oberfläche 33 der Stütze 30 über einen größeren Abschnitt einem Teilkreis angenähert, dessen Mittelpunkt etwa mit den Scharnieraichsen der ersten Scharniere 12a, 12b zusammenfällt oder in einem geringen Abstand zu diesen liegt.In contrast, in Fig. 2 the device 2 shown in its (closed) operating position; in which the two supports with their base elements 6a, 6b along the axis 8 are moved towards each other so that the first Hinges 12a, 12b are aligned with their hinge axes coaxially with each other. So that the first legs 10a, 10b of the base elements 6a, 6b do not collide with each other, they are arranged a little offset from one another. The same applies to the support 30. Like Fig. 2 can be seen, the surface 33 of the support 30 is approximated over a larger portion of a pitch circle whose center coincides with the hinge arms of the first hinges 12a, 12b, or at a small distance therefrom.

Ferner lässt Fig. 2 den (linken) Dorn 16a in seiner horizontalen ersten Stellung und den (rechten) Dorn 16b in seiner zurückgeschwenkten zweiten Stellung erkennen. Die beiden unterschiedlichen Stellungen sind aus Gründen der besseren Anschaulichkeit in Fig. 2 dargestellt. Allerdings sei an dieser Stelle angemerkt, dass beide Dornen 16a, 16b bzw. beide einander gegenüberliegende Dornenreihen stets symmetrisch zueinander verschwenkt werden.Further leaves Fig. 2 recognize the (left) mandrel 16a in its horizontal first position and the (right) mandrel 16b in its zurückgeschwenkten second position. The two different positions are for better clarity in Fig. 2 shown. However, it should be noted at this point that both spines 16a, 16b or both opposing rows of spines are always pivoted symmetrically to each other.

Fig. 3 zeigt schematisch eine Funktionsskizze der Vorrichtung, welche dem Zustand von Fig. 1 entspricht und außerdem weitere Einzelheiten der Vorrichtung erkennen lässt. Hiernach wird die Stütze 30 durch zwei seitliche Führungsplatten 34, 35 eingerahmt, die sich auf der Höhe der Dornen 16a, 16b trichterförmig erweitern. Ferner ist die Vorrichtung 2 benachbart zu einem Revolver 40 angeordnet, der Teil einer Anlage zur Herstellung von Nutzen bzw. Papierblöcken ist und die Nutzen durch Rotation von einer Arbeitsstation zur nächsten transportiert. An dem Revolver 40 sind zwei Andruckplatten 41, 42 in radialer Ausrichtung und voneinander beabstandet befestigt, die wiederum mit einer Hebevorrichtung 43, 44 fest verbunden sind. Die beiden Andruckplatten 41, 42 dienen zur Halterung eines Nutzens 50 mittels Reibschluss. In einem abgesenkten Zustand drücken die beiden Andruckplatten 41, 42 den Nutzen 50 so zusammen, dass er unverrückbar fixiert ist. Auf diese Weise kann sich der aus einzelnen Folien bestehende Nutzen 50 weder in seiner Form verändern noch sich gegenüber dem Revolver 40 verschieben. Dabei ist der Nutzen 50 so angeordnet, dass er mit seinem Randabschnitt 51, wo in den Folien eine in den Figuren 3 und 4 im einzelnen nicht dargestellte Lochreihe durch Stanzen in einer vorangegangenen Arbeitsstation ausgebildet worden ist, zur Vorrichtung 2 zeigt. Fig. 3 schematically shows a Funktionssskizze the device, which the state of Fig. 1 corresponds and also reveals further details of the device. Thereafter, the support 30 is framed by two lateral guide plates 34, 35, which extend funnel-shaped at the height of the spines 16a, 16b. Further, the apparatus 2 is disposed adjacent to a turret 40, which is part of a plant for the production of paper blocks and which transports the benefits by rotation from one work station to the next. On the revolver 40 are two pressure plates 41, 42 fixed in radial alignment and spaced from each other, which in turn are fixedly connected to a lifting device 43, 44. The two pressure plates 41, 42 serve to hold a benefit 50 by means of frictional engagement. In a lowered state, the two pressure plates 41, 42 compress the use 50 so that it is immovably fixed. In this way, the utility of individual films 50 can neither change in shape nor move relative to the revolver 40. In this case, the utility 50 is arranged so that it with its edge portion 51, where in the slides in the FIGS. 3 and 4 not shown in detail hole series has been formed by punching in a previous workstation, the device 2 shows.

In Fig. 3 ist ein Zustand dargestellt, wo der Nutzen 50 mit seinem Randabschnitt 51 bereits zwischen die Führungsplatten 34, 35 eingefahren ist.In Fig. 3 is shown a state where the benefit 50 with its edge portion 51 is already retracted between the guide plates 34, 35.

Im nächsten Schritt werden die Dorne 16a, 16b in die in den Figuren 3 und 4 nicht dargestellte Lochreihe im Randabschnitt 51 des Nutzens 50 eingefahren, wie Fig. 4 erkennen lässt. Hierzu werden die Supports 4a, 4b in die in Fig. 2 gezeigte Stellung verfahren, wobei sich die Dorne 16a, 16b in ihrer horizontalen ersten Stellung befinden. Dabei berühren sich die einander gegenüberliegenden Dorne 16a, 16b mit ihrem Spitzen 17a, 17b. Um allerdings eine direkte Kollision der Spitzen 17a, 17b miteinander zu vermeiden, sind die Dorne 16a, 16b geringfügig versetzt zueinander ausgerichtet.In the next step, the mandrels 16a, 16b in the in the FIGS. 3 and 4 Not shown row of holes in the edge portion 51 of the utility 50 retracted as Fig. 4 lets recognize. For this purpose, the supports 4a, 4b in the in Fig. 2 shown position, with the pins 16a, 16b are in their horizontal first position. In this case, the opposing mandrels 16a, 16b touch with their tips 17a, 17b. However, in order to avoid a direct collision of the tips 17a, 17b with each other, the mandrels 16a, 16b are slightly offset from one another.

Anschließend werden die die Dorne 16a, 16b tragenden ersten Hebel 14a, 14b nach unten verschwenkt, wodurch die Spitzen 17a, 17b der Dorne 16a, 16b eine totkreisförmige Bahn beschreiben. Dies ist beispielhaft in Fig. 5 anhand des (rechten) Dornes 16b schematisch gezeigt. Auch wenn in Fig. 5 der (linke) Dorn 16a in seiner horizontalen ersten Stellung gezeigt ist; so sei an dieser Stelle noch einmal darauf hingewiesen, dass sich beide Dorne 16a, 16b bzw. beide Dornenreihen symmetrisch zueinander bewegen und somit auch der linke Dorn 16a von Fig. 5 gleichzeitig die gleiche teilkreisförmige Bahn wie der rechte Dorn 16b beschreibt.Subsequently, the first lever 14a, 14b carrying the mandrels 16a, 16b are pivoted downward, whereby the tips 17a, 17b of the mandrels 16a, 16b describe a dead-circular path. This is exemplary in Fig. 5 schematically shown by the (right) mandrel 16b. Even if in Fig. 5 the (left) mandrel 16a is shown in its horizontal first position; It should be pointed out again at this point that both mandrels 16a, 16b or both rows of thorns move symmetrically to each other and thus also the left mandrel 16a of Fig. 5 at the same time describes the same part-circular path as the right mandrel 16b.

Während die Dorne 16a, 16b in die Lochreihe des Nutzens 50 eingefahren und anschließend in der zuvor beschriebenen Weise verschwenkt werden, liegt der Nutzen 50 mit seinem die Lochreihe aufweisenden Randabschnitt 51 auf dem Kopf 32 der Stütze 30 auf.While the mandrels 16 a, 16 b are inserted into the row of holes of the utility 50 and then pivoted in the manner described above, the utility 50 with its hole row having edge portion 51 on the head 32 of the support 30 on.

Die zuvor beschriebene Schwenkbewegung der Dorne 16a, 16b hat nun zur Folge, dass die Folien des Nutzens 50 so zueinander verschoben werden, dass die einzelnen Löcher der Lochreihe im Nutzen 50 eine entsprechend gekrümmte Form bzw. Ausrichtung erhalten. Gleichzeitig wird durch die Schwenkbewegung der Dorne 16a, 16b bewirkt, dass der Nutzen 50 mit seinem Randabschnitt 51 im Wesentlichen über seine gesamte Breite in Anlage an die gekrümmte Oberfläche 33 der Stütze 30 gelangt, welche insoweit als eine Art Lehre dient.The above-described pivotal movement of the mandrels 16a, 16b has the consequence that the films of the utility 50 are shifted relative to one another in such a way that the individual holes of the row of holes in the utility 50 receive a correspondingly curved shape or orientation. At the same time, the swiveling movement of the mandrels 16a, 16b causes the benefit 50 with its edge section 51 to come into abutment against the curved surface 33 of the support 30 substantially over its entire width, which serves as a kind of teaching.

Dieser Zustand ist in Fig. 6 schematisch dargestellt. Insbesondere lässt Fig. 6 den gekrümmten Verlauf eines Loches 52 der im Randabschnitt 51 des Nutzens 50 ausgebildeten Lochreihe erkennen. An dieser Stelle sei der guten Vollständigkeit halber noch angemerkt, dass auch in Fig. 6 die Dorne 16a, 16b in ihren beiden Stellungen gezeigt sind, und zwar in durchgezogenen Linien in der horizontalen ersten Stellung und in gestrichelten Linien in der zurückgeschwenkten zweiten Stellung, in der sie sich ja bereits außerhalb des Nutzens 50 befinden. Das Zurückschwenken der Dorne 16a, 16b in die zweite Stellung hat demnach zur Folge, dass gleichzeitig die Dorne 16a, 16b während ihrer Schwenkbewegung aus den Löchern 52 der Lochreihe herausgezogen werden. Wie bereits erwähnt, beschreiben während dieser Schwenkbewegung die Spitzen 17a, 17b der Dorne 16a, 16b eine teilkreisförmige, im dargestellten Ausführungsbeispiel etwa achtelkreisförmige, Bahn um die koaxial zueinander liegenden Scharnierachsen der ersten Scharniere 12a, 12b. Demnach ist der so entstehende gekrümmte Verlauf der Löcher 52 zumindest über einen größeren Abschnitt etwa einem Teilkreis angenähert.This condition is in Fig. 6 shown schematically. In particular, lets Fig. 6 recognize the curved course of a hole 52 formed in the edge portion 51 of the utility 50 series of holes. At this point, the sake of completeness, it should be noted that also in Fig. 6 the mandrels 16a, 16b are shown in their two positions, in solid lines in the horizontal first position and in dashed lines in the zurückgeschwenkten second position in which they are already outside of the benefit 50. The pivoting back of the mandrels 16a, 16b in the second position thus has the consequence that at the same time the mandrels 16a, 16b are pulled out during their pivoting movement from the holes 52 of the row of holes. As already mentioned, the tips 17a, 17b of the mandrels 16a, 16b during this pivotal movement describe a partially circular, in the illustrated embodiment approximately achtelkreisförmige, track around the coaxial with each other hinge axes of the first hinges 12a, 12b. Accordingly, the resulting curved course of the holes 52 is approximated at least over a larger portion about a pitch circle.

Wenn zum Binden des Nutzens 50 insbesondere eine Drahtwendel verwendet werden soll, ist es sinnvoll, während der zuvor beschriebenen Schwenkbewegung die Dorne 16a, 16b gleichzeitig einer weiteren relativ geringen seitlichen Schwenkbewegung um die Achse 8 zu unterwerfen, wozu die Sockelelemente 6a, 6b um die Achse 8 angeordnet sind und um einen Winkel gekippt werden, der etwa der Steigung der einzudrehenden Drahtwendel entspricht. Hierzu muss die in den Figuren nicht dargestellte Antriebseinrichtung entsprechend angepasst sein und sollte vorzugsweise eine ebenfalls nicht dargestellte, jedoch im Stand der Technik bereits bekannte Kulissenführung aufweisen.If, in particular, a wire helix is to be used for binding the utility 50, it makes sense to subject the mandrels 16a, 16b simultaneously to a further relatively small lateral pivotal movement about the axis 8 during the pivoting movement described above, for which purpose the base elements 6a, 6b about the axis 8 are arranged and tilted at an angle which corresponds approximately to the slope of the einzudrehenden wire helix. For this purpose, the drive device, not shown in the figures, must be adapted accordingly and should preferably also have a gate guide, also not shown, but already known in the prior art.

Ergänzend sei an dieser Stelle noch angemerkt, dass während der beschriebenen Schwenkbewegung der Dorne 16a, 16b der Anpressdruck der in den Figuren 3 und 4 gezeigten Andruckplatten 41, 42 soweit gelockert wird, dass zwar der Nutzen 50 zwischen diesen fixiert bleibt, jedoch dessen einzelne Folien sich in der beschriebenen Weise ausrichten lassen.In addition, it should be noted at this point that during the described pivotal movement of the mandrels 16a, 16b of the contact pressure in the FIGS. 3 and 4 shown pressure plates 41, 42 is loosened so much that, although the benefit 50 remains fixed between them, but its individual films can be aligned in the manner described.

In der in Fig. 6 gezeigten Ausrichtung sind nun die Löcher 52 im Nutzen 50 vorbereitet, um im nächsten Arbeitsschritt ein gekrümmtes Verbindungsmittel, insbesondere eine Drahtwendel aufzunehmen, die entsprechend durch die Löcher 52 eingedreht wird. In Fig. 6 ist schematisch in strichpunktierter Linie 54 der kreisförmige Querschnitt einer durch die Löcher 52 einzudrehenden Drahtwendel angedeutet, wobei deren Mittelachse im hier dargestellten Ausführungsbeispiel in einem geringen Abstand oberhalb von und parallel zu den übereinstimmenden Scharnierachsen der ersten Scharniere 12a, 12b verläuft.In the in Fig. 6 shown alignment are now the holes 52 in the utility 50 prepared to receive in the next step, a curved connecting means, in particular a wire coil, which is screwed through the holes 52 accordingly. In Fig. 6 is schematically indicated in dash-dotted line 54 of the circular cross section of a einzudrehenden through the holes 52 wire coil, wherein the central axis in the embodiment shown here at a small distance above and parallel to the matching hinge axes of the first hinges 12a, 12b.

Ferner sind in Fig. 6 Distanzleisten 56a, 56b dargestellt, die in den ersten Hebeln 14a, 14b angeordnet sind und die Dorne 16a, 16b tragen, so dass diese über die Distanzleisten 56a, 56b an den ersten Hebeln 14a, 14b entsprechend gehaltert sind. Mit Hilfe der Distanzleisten 56a, 56b lässt sich das radiale Abstandsmaß R (siehe Fig. 1) einstellen. Hierzu sind die Distanzleisten 56a, 56b entweder verstellbar oder austauschbar an den ersten Hebeln 14a, 14b befestigt.Furthermore, in Fig. 6 Spacer strips 56a, 56b are shown, which are arranged in the first levers 14a, 14b and carry the pins 16a, 16b, so that they are supported by the spacer strips 56a, 56b on the first levers 14a, 14b, respectively. With the aid of the spacer strips 56a, 56b, the radial distance R (see Fig. 1 ) to adjust. For this purpose, the spacer strips 56a, 56b either adjustable or replaceable attached to the first levers 14a, 14b.
