Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Verbinden von aus übereinanderliegenden und stetig transportierten Bahnen oder Bogen aus Papier oder dgl. gebildeten Produkten mittels eines drahtartigen und zu einzelnen Klammern verformbaren Heftmaterials, bestehend aus einer Vorratsrolle mit Fördereinheit für das Heftmaterial, einer das Heftmaterial auf Klammerlänge abtrennenden Schneideinrichtung, einer Klammerformeinheit, einem Stößel zum Einbringen der geformten Klammern in das Produkt und einem Klammerschließer. Eine solche Vorrichtung ist beispielsweise aus Dokument GB-A-2 027 630 bekannt.The invention relates to a device for connecting from overlapping and constantly transported Sheets or sheets formed from paper or the like Products by means of a wire-like and individual Staples of deformable booklet material, consisting of a Supply roll with conveyor unit for the binding material, one cutting device cutting the stapling material to the clip length, a staple forming unit, a plunger for Insert the shaped brackets into the product and one Clamp closers. Such a device is for example from document GB-A-2 027 630 known.

Zeitschriften, Broschüren, Prospekte oder dgl., die aus mehreren Blättern bzw. Doppelblättern bestehen, werden zunächst aus einzelnen, übereinanderliegenden und stetig transportierten Bahnen oder bereits davon abgeschnittenen Bögen aus Papier oder dgl. gebildet, die dann durch eine Heftung mittels zwei oder mehr zueinander fluchtender Heftklammern, vorwiegend aus Metall, miteinander verbunden werden. Anschließend werden die Bahnen oder Bögen im Bereich der Heftklammern gefaltet und geschnitten bzw. beschnitten.Magazines, brochures, prospectuses or the like, made from multiple sheets or double sheets exist first from individual, one above the other and steady transported webs or already cut off Sheets of paper or the like. Formed by a Stapling using two or more staples aligned with each other, predominantly made of metal. Then the tracks or arches in the area of the staples folded and cut or trimmed.

Für das Anbringen der Heftklammern sind Vorrichtungen bekannt, die aus oberhalb und unterhalb der Bahnen oder Bögen in Transportrichtung hin- und herbewegbaren Schlitten bestehen, die für das Anbringen der Heftklammern kurzzeitig auf die Transportgeschwindigkeit der Bahnen oder Bögen beschleunigt werden. Diese Schlitten sind mit einem oder mehreren Heftköpfen bestückt, wobei jeder Heftkopf aus einem im unteren und einem im oberen Schlitten angeordneten Teil besteht. Der eine Teil des Heftkopfes dient dabei zum Einbringen der Heftklammern in die aus den Bahnen oder Bögen zu bildenden Produkte, während durch den anderen Teil der Heftköpfe die eine U-förmige Gestalt aufweisenden Klammern geschlossen werden. Die zu verarbeitenden Heftklammern können entweder vorgefertigt sein oder in dem Teil des Heftkopfes gebildet werden, der zum Einbringen der geformten Klammern in die zu heftenden Produkte dient. Aufgrund der Tatsache, daß die die Heftkopfteile tragenden Schlitten einerseits zunächst auf die Geschwindigkeit der transportierten, aus übereinanderliegenden Bahnen oder Bogen gebildeten Produkte beschleunigt, anschließend verzögert und dann in entgegengesetzter Richtung wieder in ihre Ausgangslage gebracht werden müssen, darf die Transportgeschwindigkeit der Produkte einen gewissen Wert nicht überschreiten, wodurch zwangsläufig der Ausstoß an fertigen Produkten zahlenmäßig beschränkt ist.Devices are known for attaching the staples, those from above and below the sheets or arches there are slides that can be moved back and forth in the direction of transport, those for attaching the staples temporarily accelerated to the transport speed of the webs or sheets become. These sledges come with one or several stitching heads, each stitching head made of one in the lower and one in the upper carriage Part exists. One part of the stitching head is used for Insert the staples into the sheets or sheets products to be formed while through the other part of the stitching heads which have a U-shaped shape Brackets are closed. The staples to be processed can either be prefabricated or in the part of the stitching head are formed, which is used to insert the shaped Brackets in the products to be stapled. Because of the fact that those carrying the stitching head parts Sled firstly on the speed of the transported, from overlapping webs or sheets formed products accelerated, then delayed and then back in the opposite direction Must be brought to the starting position, the transport speed the products do not exceed a certain value, which inevitably means the output of finished Products is limited.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung zum Verbinden von aus übereinanderliegenden und stetig transportierten Bahnen oder Bogen aus Papier oder dergleichen gebildeten Produkten mittels eines drahtartigen und zu einzelnen Klammern verformbaren Heftmaterials zu schaffen, die eine höhere Transportgeschwindigkeit für die aus den übereinanderliegenden Bahnen oder Bogen gebildeten Produkte ermöglicht und mit der dadurch ein erhöhter Ausstoß an gehefteten Produkten erreicht wird. The invention is therefore based on the object Device for connecting from one another and constantly transported webs or sheets of paper or the like formed products by means of a wire-like and staple material deformable into individual staples to create the higher transportation speed for those formed from the superimposed webs or sheets Products enabled and with it an increased Output on stapled products is achieved.

Zur Lösung dieser Aufgabe werden gemäß der Erfindung bei einer Vorrichtung der eingangs beschriebenen Gattung die im Kennzeichen des Anspruches 1 aufgeführten Merkmale vorgeschlagen.To solve this problem, according to the invention a device of the type described above Features listed in the characterizing part of claim 1 suggested.

Durch eine solche Vorrichtung können die bisher benötigten Schlitten entfallen. Die rotierenden Teile der Vorrichtung, die die Vorratsrrolle, die Klammerformeinheit, den Stößel und den Klammerschließer tragen, können stets mit einer Umfangsgeschwindigkeit umlaufen, die genau der Transportgeschwindigkeit der aus den übereinanderliegenden Bahnen oder Bogen gebildeten Produkte entspricht. Eine Beschleunigung oder Verzögerung und eine Bewegungsumkehr sind nicht mehr erforderlich. Dadurch lassen sich höhere Transportgeschwindigkeiten der zu heftenden Produkte und damit ein erhöhter Ausstoß an fertigen Produkten erreichen. Dazu tragen auch die geringeren Massen der Vorrichtung bei.With such a device the previously required No sledges. The rotating parts of the device, which is the supply roll, the staple forming unit, the pestle and wear the clamp closer, can always with a peripheral speed circulate that exactly the transport speed that from the superimposed webs or Arc formed products corresponds. An acceleration or delay and a reversal of motion are no longer required. This enables higher transport speeds of the products to be stapled and thus one achieve higher output on finished products. Wear with it also the lower masses of the device.

In der Fig. 1 der Zeichnung ist in stark vereinfachter Weise eine Vorrichtung gezeigt, die zum Verbinden von aus übereinanderliegenden und stetig transportierten Bahnen oder Bogen aus Papier oder dgl. gebildeten Produkten 1 mittels eines drahtartigen und zu einzelnen Klammern verformbaren Heftmaterials dient. Dabei werden die Produkte 1 in Richtung eines Pfeiles 2 mit einer vorgegebenen Geschwindigkeit durch die Vorrichtung bewegt.In Fig. 1 of the drawing is in a very simplified manner shown a device for connecting from one another and constantly transported webs or sheets formed from paper or the like. 1 by means of a wire-like stapling material that can be deformed into individual staples serves. In doing so, the products 1 are in the direction an arrow 2 at a predetermined speed moved by the device.

Die erfindungsgemäße Vorrichtung besteht zunächst aus einem trommelartigen Körper 3, der sich im dargestellten Ausführungsbeispiel oberhalb der zu heftenden Produkte 1 befindet und der um eine Achse 4 drehbar gelagert ist. Mit dem trommelartigen Körper 4 ist beispielsweise mindestens eine nicht gezeichnete Vorratsrrolle verbunden, auf der das Heftmaterial 6, beispielsweise Draht, aufgewickelt ist. Dieses Heftmaterial 6 wird nun über nicht dargestellte Öffnungen und Schlitze bis zu zwei Förderrollen 7 geführt, die senkrecht zur Zeichnungsebene nebeneinander angeordnet sind und von denen daher nur die vordere Förderrolle 7 zu erkennen ist. Zumindest eine dieser Förderrollen 7 kann so angetrieben werden, daß das Heftmaterial 6 schrittweise um einen vorgegebenen, einstellbaren Betrag von der Vorratsrolle 5 abgezogen wird.The device according to the invention initially consists of a drum-like body 3, which is in the illustrated embodiment located above the products to be stapled 1 and which is rotatably mounted about an axis 4. With the drum-like Body 4, for example, is not at least one drawn supply roll connected on which the tack material 6, for example wire, is wound up. This booklet material 6 is now via openings and not shown Slits guided up to two conveyor rollers 7, which are vertical are arranged side by side to the plane of the drawing and from which therefore only the front conveyor roller 7 can be seen. At least one of these conveyor rollers 7 can be driven in this way be that the booklet material 6 gradually by a predetermined, adjustable amount deducted from the supply roll 5 becomes.

Im dargestellten Ausführungsbeispiel ist die Förderrolle 7 auf einer Hülse 8 angeordnet, die auf einem Zapfen 9 drehbar gelagert ist. Die Hülse 8 ist mit einem an sich bekannten, nur angedeuteten Freilauf 10 verbunden, der so ausgestaltet ist, daß er die Hülse 8 nur in einer Drehrichtung mitnimmt. Ferner wird der Freilauf 10 von einem verzahnten Ring 11 umschlossen, der mit einer Zahnstange 12 kämmt. Immer dann, wenn sich die Zahnstange 12 in Richtung auf den Zapfen 9 bewegt, wird über den verzahnten Ring 11, den Freilauf 10 und die Hülse 8 die Förderrolle 7 gedreht und damit das drahtartige Heftmaterial 6 um einen entsprechenden Betrag verschoben.In the illustrated embodiment, the conveyor roller is 7 arranged on a sleeve 8 which is rotatable on a pin 9 is stored. The sleeve 8 is with a known, connected only indicated freewheel 10, which is configured is that he the sleeve 8 only in one direction of rotation takes along. Furthermore, the freewheel 10 is toothed Enclosed ring 11 which meshes with a rack 12. always then when the rack 12 in the direction of the Pin 9 moves, is on the toothed ring 11, the Freewheel 10 and the sleeve 8, the conveyor roller 7 rotated and thus the wire-like booklet material 6 by a corresponding one Amount shifted.

Zur Bewegung der Zahnstange 12 ist mit Abstand um den trommelartigen Körper 3 ein ortsfester Ring 13 angeordnet, der mit der Hubkurve 14 ausgestattet ist. Auf dieser ringförmig verlaufenden Hubkurve 14 rollt ein beispielsweise durch ein Kugellager gebildetes Laufrad 15 ab, dessen Lagerzapfen 16 fest mit der Zahnstange 12 verbunden ist. Bei einer Drehbewegung des trommelartigen Körpers 3 rollt das Laufrad 15 über die Hubkurve 14 und verschiebt die Zahnstange 12 von dem Zapfen 9 weg. Bei dieser Bewegung der Zahnstange 12 führt die Förderrolle 7, durch den Freilauf 10 bedingt, keinerlei Bewegung aus. Die Zahnstange 12 stützt sich mit ihrem freien Ende nahe des Lagerzapfens 16 an einer vorgespannten Druckfeder 17, die die Zahnstange 12 in Abhängigkeit von der Hubkurve 14 wieder in die entgegengesetzte Richtung und damit in Richtung auf den Zapfen 9 bewegt. Dies bedeutet, daß die Zahnstange 12 bei einer Umdrehung des trommelartigen Körpers 3 einen Transporthub für das Heftmaterial 6 und einen Leerhub ausführt. Durch Auswechseln des Ringes 13 mit der Hubkurve 14 kann die axiale Verschiebung der Zahnstange 12 verändert und den jeweiligen Bedürfnissen angepaßt werden.To move the rack 12 is at a distance around the drum-like Body 3 arranged a stationary ring 13, the is equipped with the stroke curve 14. On this ring-shaped extending stroke curve 14 rolls through, for example Ball bearing formed impeller 15, the bearing pin 16 is firmly connected to the rack 12. With a rotary movement of the drum-like body 3 rolls the impeller 15 over the stroke curve 14 and moves the rack 12 of the pin 9 away. During this movement of the rack 12 guides the conveyor roller 7, due to the freewheel 10, no movement. The rack 12 is supported with its free end near the bearing pin 16 on a biased Compression spring 17, which the rack 12 in dependence from the stroke curve 14 back into the opposite Direction and thus in the direction of the pin 9 moves. This means that the rack 12 at one revolution of the drum-like body 3 a transport stroke for the Stapling material 6 and an idle stroke. By changing of the ring 13 with the stroke curve 14 can be the axial Displacement of the rack 12 changed and the respective Be adapted to needs.

Über die Förderrollen 7 wird das drahtartige Heftmaterial 6 um eine vorgegebene Länge aus dem trommelartigen Körper 3 herausbewegt und in Bohrungen 18, 19 eines Messers 20 und einer Halterung 21 eingeführt. Zwischen dem Messer 20 und der Halterung 21 befindet sich ein Stößel 22. Sobald die Förderung des drahtartigen Heftmaterials 6 beendet ist, wird das Messer 20 in radialer Richtung nach außen bewegt und damit von dem Heftmaterial 6 ein gerades Stück für eine Klammer 37 abgetrennt, welches jedoch in den Bohrungen 18, 19 des Messers 20 und der Halterung 21 verbleibt. Zur radialen Bewegung des Messers 20 ist dasselbe mit einem Stift 23 verbunden, dessen freies Ende ein Kugellager 24 trägt. Das Kugellager 24 wird von einer Führungsnut 25 aufgenommen, die in einem ortsfesten, dem trommelartigen Körper 3 vorgeordneten Teil 26 ausgebildet ist. Die umlaufende Führungsnut 25 ist nun so geformt, daß dieselbe über ihren Umfang einen unterschiedlichen radialen Abstand zur Achse 4 aufweist, was dazu führt, daß das Messer 20 eine Schneidbewegung und eine Rückbewegung ausführen kann.The wire-like stapling material 6 is conveyed over the conveyor rollers 7 by a predetermined length from the drum-like body 3 moved out and in holes 18, 19 of a knife 20 and a bracket 21 introduced. Between the knife 20 and the bracket 21 is a plunger 22. Once the Conveyance of the wire-like binding material 6 has ended, the knife 20 is moved outwards in the radial direction and thus of the booklet material 6 a straight piece for one Clamp 37 separated, which, however, in the holes 18, 19 of the knife 20 and the holder 21 remains. For radial movement of the knife 20 is the same with one Pin 23 connected, the free end of a ball bearing 24th wearing. The ball bearing 24 is guided by a guide groove 25 recorded in a stationary, the drum-like Body 3 upstream part 26 is formed. The circulating Guide groove 25 is now shaped so that the same over their circumference a different radial distance from Has axis 4, which leads to the knife 20 a Cutting movement and a return movement can perform.

Auch der Stößel 22 ist mit einem Stift 27 verbunden, dessen freies Ende auch mit einem Kugellager 28 bestückt ist. Das Kugellager 28 ist in einer umlaufenden Führungsnut 29 des ortsfesten Teiles 26 gehalten, die ebenfalls über ihren Umfang einen unterschiedlichen axialen Abstand zur Achse 4 aufweist. Dies führt dazu, daß auch der Stößel 22 bei einer Umdrehung des trommelartigen Körpers 3 einen Arbeitshub und einen Rückhub ausführt, auf die weiter unten noch eingegangen wird.The plunger 22 is connected to a pin 27, the free end is also equipped with a ball bearing 28. The Ball bearing 28 is in a circumferential guide groove 29 of the held stationary part 26, which also over their Circumference a different axial distance from axis 4 having. This leads to the fact that the plunger 22 at one Rotation of the drum-like body 3 a working stroke and performs a return stroke, which will be discussed further below becomes.

Neben dem trommelartigen Körper 3 befindet sich seitlich versetzt eine Achse 31, die parallel zur Achse 4 verläuft. Diese Achse 31 nimmt einen Drehkörper 32 auf, in dem eine in Fig. 1 nur angedeutete Nut 33 ausgebildet ist. In dieser Nut 33 ist ein stößelartiger Klammerformer 34 radial verschiebbar geführt, der über einen Exzenter 35 - es kann auch eine Führungsnut sein - radial verschoben wird. Über diesen Exzenter 35 kann der Klammerformer 34 in eine nicht näher dargestellte und am trommelartigen Körper 3 im Bereich der Führung des Stößels 22 ausgebildete und von dem Messer 20 und der Halterung 21 begrenzte Tasche eingeführt werden. Dabei beginnt der Klammerformer 34 sein Eindringen in diese Tasche immer dann, wenn der trommelartige Körper 3 aus der gezeichneten Stellung der Fig. 1 einen Drehwinkel von etwa 225° zurückgelegt hat. Nach einem Winkel des trommelartigen Körpers 3 von etwa 270° bis 280° verläßt der Klammerformer 34 die Tasche wieder. Bei diesem Eindringen des Klammerformers 34 in die Tasche wird das zuvor abgetrennte Stück des Heftmaterials 6 zu einer U-förmigen Klammer 37 verformt. Dabei ist es Voraussetzung, daß der trommelartige Körper 3 und der Drehkörper 32 synchron angetrieben werden, was in vorteilhafterweise über Zahnräder erfolgen kann.In addition to the drum-like body 3 is located on the side offsets an axis 31 that runs parallel to axis 4. This axis 31 receives a rotating body 32 in which one in Fig. 1 only indicated groove 33 is formed. In this Groove 33 is a plunger-like clamp former 34 which can be moved radially led out through an eccentric 35 - it can also be a guide groove - is moved radially. over this eccentric 35 can not form the staple 34 in a shown in more detail and on the drum-like body 3 in the area the leadership of the plunger 22 trained and by the Knife 20 and the holder 21 inserted pocket become. The staple former 34 begins to penetrate in this pocket whenever the drum-like body 3 from the drawn position of FIG. 1 an angle of rotation of about 225 °. After an angle of the drum-like Body 3 of about 270 ° to 280 ° leaves the Clip former 34 the bag again. With this intrusion of the staple former 34 in the pocket is the previously separated Piece of tack material 6 to a U-shaped bracket 37 deformed. It is a prerequisite that the drum-like Body 3 and the rotating body 32 driven synchronously be what are advantageously done via gears can.

Sobald der Klammerformer 34 die Tasche am trommelartigen Körper 3 verlassen hat, beginnt die Einleitung der radialen Bewegung des Stößels 22 nach außen. Bei dieser Bewegung gelangt auch die zuvor gebildete Klammer 37 in den Bereich des transportierten Produktes 1, durch das bei der weiteren Bewegung des trommelartigen Körpers 3 und weiteren radialen Bewegung des Stößels 22 die zuvor gebildete, U-förmige Klammer 37 mit ihren Schenkeln zunächst eingestoßen und dann durchgestoßen wird.Once the staple shaper 34 the bag on the drum Has left body 3, the initiation of the radial begins Movement of the plunger 22 outwards. With this movement also the previously formed bracket 37 in the area of transported product 1, by the further movement of the drum-like body 3 and other radial Movement of the plunger 22 the previously formed U-shaped bracket 37 first kicked in with her thighs and then is pushed through.

Unterhalb des Produktes 1 befindet sich ein sogenannter Klammerschließer 40, der gemaß der Fig. 3 oder der Fig. 4 ausgebildet sein kann. Dieser Klammerschließer 40 ist an einem Drehkörper 41 ausgebildet, der auf einer Achse 42 gelagert ist. Dabei verläuft die Achse 42 parallel zur Achse 4. Über an sich bekannte, in der Zeichnung nicht dargestellte Zahnräder ist der Drehkörper 41 mit dem trommelartigen Körper 3 in Eingriff und führt normalerweise eine synchrone Bewegung zu demselben aus. Gemäß der Fig. 3 ist in dem Drehkörper 41 ein Stößel 43 radial verschiebbar gelagert, der eine Zunge 44 trägt. Die Zunge 44 ist an ihrer freien Stirnfläche mit an sich bekannten und nicht dargestellten Schließmulden versehen. Der Stößel 43 trägt einen Stift 45, der an seinem aus dem Stößel 43 herausragenden Ende mit einem Kugellager 46 bestückt ist. Dieses Kugellager 46 wird von einer Führungsnut 47 aufgenommen, die in einem ortsfesten, also nicht drehbaren Teil ausgebildet ist. Diese Führungsnut 47 weist einen unterschiedlichen radialen Abstand zur Achse 42 auf. Dies hat zur Folge, daß bei einer Umdrehung des Drehkörpers 41 der Stößel 43 und damit die Zunge 44 radial nach außen und zurück bewegt werden.Below the product 1 there is a so-called Clip closer 40, which according to FIG. 3 or FIG. 4 can be trained. This clamp closer 40 is on a rotating body 41 which is mounted on an axis 42 is. The axis 42 runs parallel to the axis 4. About known, not shown in the drawing Gears is the rotating body 41 with the drum-like Body 3 engages and usually performs one synchronous movement to the same. 3 is a plunger 43 is mounted radially displaceably in the rotating body 41, who wears a tongue 44. The tongue 44 is on hers free end face with known and not shown Provide locking recesses. The plunger 43 carries one Pin 45, the protruding from the plunger 43 End is equipped with a ball bearing 46. This ball bearing 46 is received by a guide groove 47 which in a fixed, so not rotatable part is. This guide groove 47 has a different radial Distance to axis 42. This has the consequence that with one revolution of the rotating body 41 of the plunger 43 and so that the tongue 44 is moved radially outwards and backwards.

Die Form der Führungsnut 47 verläuft nun so, daß dann, wenn sich der Drehkörper 41 mit dem Stößel 43 seiner dargestellten Lage gemäß Fig. 1 nähert, der Stößel 43 und damit die Zunge 44 radial in Richtung auf den trommelartigen Körper 3 bewegt wird. Zu diesem Zeitpunkt hat die gebildete Klammer 37 mit ihren Schenkeln bereits das Produkt 1 durchstoßen. Durch die Zunge 44 werden nun die Schenkelenden der gebildeten Klammer 37 erfaßt und nach innen umgebogen. Damit ist die Heftverbindung fertiggestellt.The shape of the guide groove 47 now runs so that when the rotating body 41 with the plunger 43 of its illustrated Approaching position according to FIG. 1, the plunger 43 and thus the Tongue 44 radially towards the drum-like body 3 is moved. At this point, the bracket formed 37 already pierce product 1 with her thighs. Through the tongue 44, the leg ends of the formed bracket 37 detected and bent inwards. In order to the binding is completed.

Bei dem Ausführungsbeispiel gemäß der Fig. 4 sind im Drehkörper 41 zwei Kipphebel 50 angeordnet, die jeweils um eine Achse 51 geschwenkt werden können. Dabei ist der in der Zeichnung rechte Kipphebel 50 in seiner Grundstellung und der linke Kipphebel 50 in seiner Schwenkstellung gezeichnet. Über eine vorgespannte Druckfeder 52 werden beide Kipphebel 50 in ihrer Grundstellung gehalten.4 are in the rotating body 41 two rocker arms 50 arranged, each by one Axis 51 can be pivoted. The is in the Drawing right rocker arm 50 in its basic position and the left rocker arm 50 is drawn in its pivoted position. Both rocker arms are via a pre-tensioned compression spring 52 50 held in their basic position.

Jeder Kipphebel 50 trägt an seinem längeren Hebelarm ein Kugellager 53, welches als Laufrolle dient. Jedes Kugellager 53 stützt sich nun über die vorgespannte Druckfeder 52 auf einer Steuerkurve 54 ab, die von einer Stirnfläche eines Ringes 55 gebildet ist. Dieser Ring 55 ist in einen nur angedeuteten Zahnkranz 56 eingesetzt, der drehfest im Drehkörper 41 gehalten ist. Bei einer Drehbewegung des Drehkörpers 41 laufen nun die Kugellager 53 auf der ebenfalls ortsfesten Steuerkurve 54. Dabei werden die Kipphebel 50 durch die Steuerkurve 54 immer gemeinsam aus ihrer jeweiligen Grundstellung in ihre Schwenkstellung bewegt, die auch als Schließstellung bezeichnet werden kann. Bei dieser Schwenkbewegung der Kipphebel 50 werden die durch das jeweilige Produkt 1 ragenden Schenkel der nur angedeuteten Klammer 37 gegeneinander gebogen und damit die Klammer 37 geschlossen. Eine Voraussetzung für diese Schließbewegung ist es jedoch, daß auch der Drehkörper 41 gemäß Fig. 4 synchron mit dem trommelartigen Körper 3 umläuft.Each rocker arm 50 carries on its longer lever arm Ball bearing 53, which serves as a roller. Every ball bearing 53 is now supported by the prestressed compression spring 52 on a cam 54 from an end face a ring 55 is formed. This ring 55 is in one only indicated sprocket 56 used, the rotationally fixed in Rotary body 41 is held. When the Rotary body 41 now run the ball bearings 53 on the likewise stationary control cam 54. The rocker arms 50 through the control curve 54 always together from their the respective basic position is moved into its swivel position, which can also be called the closed position. At this pivoting movement of the rocker arm 50 are the through the respective product 1 projecting leg of the only indicated Bracket 37 bent against each other and thus the bracket 37 closed. A prerequisite for this closing movement it is, however, that the rotating body 41 according to Fig. 4 revolves synchronously with the drum-like body 3.

In Abänderung des erläuterten Ausführungsbeispieles ist es möglich, die radialen Bewegungen des Messers 20, des Stößels 22, des Klammerformers 34 und des Stößels 43 sowie die Schwenkbewegungen der Kipphebel 50 in anderer Weise zu steuern. Dabei muß jedoch immer sichergestellt sein, daß diese Bewegungen zum richtigen Zeitpunkt durchgeführt werden und synchron ablaufen.In modification of the illustrated embodiment it is possible to control the radial movements of the knife 20, the Tappet 22, the bracket former 34 and the tappet 43 and the pivoting movements of the rocker arms 50 in a different way Taxes. However, it must always be ensured that these movements are done at the right time and run synchronously.
