Description

Die Erfindung betrifft eine Drahtheftmaschine nach dem Oberbegriff des Anspruchs 1. Drahtheftmaschinen dieser Art weisen mitlaufende Heftköpfe auf und ermöglichen das Heften von Produkten im Durchlauf. Die Produkte müssen somit zum Heften nicht angehalten und anschliessend beschleunigt werden. Heftmaschinen dieser Art sind in der Praxis bekannt und ermöglichen eine vergleichsweise hohe Produktionsgeschwindigkeit. Eine solche Heftmaschine ist beispielsweise in der CH-A-662 987 des Anmelders offenbart.The invention relates to a wire stitching machine according to the preamble of claim 1. wire stitching machines of this type running stapling heads and enable stapling of products in the run. The products must therefore be stapled not stopped and then accelerated. staplers this type is known in practice and enables a comparatively high production speed. Such a stapling machine is, for example, in CH-A-662 987 of the applicant.

Diese Heftmaschinen sind jedoch fest für eine Kettenteilung von 21 Zoll oder 14/15 Zoll ausgelegt. Dies hat folgende Nachteile. Ist beispielsweise ein Sammelhefter mit einer Kettenteilung von 21 Zoll vorhanden, so können Produkte in einem Formatbereich von DIN A5 bis A3 und sogenannte Doppelnutzenprodukte verarbeitet werden. Bei Produkten mit dem Format A4 arbeitet die Maschine dann aber lediglich mit einer Leistung von 14'000 bis 15'000 Exemplaren pro Stunde. Mit einem Sammelhefter, der eine Kettenteilung von 15 Zoll aufweist, können Produkte mit dem Format A4 mit einer wesentlich höheren Leistung von 18'000 Exemplaren pro Stunde verarbeitet werden. However, these staplers are fixed for chain division of 21 inches or 14/15 inches. This has the following Disadvantage. For example, is a saddle stitcher with a chain pitch of 21 inches available, so products can be rolled into one Format range from A5 to A3 and so-called double-use products are processed. For products with A4 format the machine then only works with one power from 14,000 to 15,000 copies per hour. With a saddle stitcher, which has a chain pitch of 15 inches A4 format products with a much higher one Output of 18,000 copies per hour can be processed.

Bei einer Maschine mit einer Kettenteilung von 15 Zoll können jedoch Produkte im Format A3 oder sogenannte Doppelnutzen nicht verarbeitet werden. Wünschbar wäre somit ein Sammelhefter mit variabler Kettenteilung. Die bekannten Drahtheftmaschinen mit fliegenden Heftköpfen sind wie bereits erwähnt auf eine feste Kettenteilung festgelegt und können nicht umgestellt werden.For a machine with a chain pitch of 15 inches however, products in A3 format or so-called double-use cannot be processed. A saddle stitcher would therefore be desirable with variable chain pitch. The well-known wire stitching machines with flying stitching heads are as already mentioned fixed on a fixed chain pitch and can not be converted become.

Der Erfindung liegt die Aufgabe zugrunde, eine Drahtheftmaschine der genannten Art zu schaffen, die in einfacher Weise an unterschiedliche Kettenteilungen anpassbar ist.The invention has for its object a wire stitching machine to create the kind mentioned in a simple way is adaptable to different chain pitches.

Die Aufgabe ist bei einer Drahtheftmaschine der genannten Art gemäss Anspruch 1 gelöst. Bei der erfindungsgemässen Drahtheftmaschine ist ein Antrieb für den Heftschlittenhub und ein separater Antrieb für den Hub des Biegers und den Hub des Treibers vorgesehen. Beide Antriebe können unabhängig voneinander umgestellt werden. Um den Heftschlittenhub beispielsweise von etwa 140 mm für eine Kettenteilung von 14 Zoll auf etwa 200 mm für 21 Zoll Kettenteilung umzustellen, muss somit lediglich der erste Antrieb für den Heftschlittenhub umgestellt werden. Der zweite Antrieb für den Hub des Biegers und den Hub des Treibers ist damit nicht beeinflusst. Die Umstellung ist deshalb konstruktiv wesentlich einfacher und kann auch von einer angelernten Bedienungsperson vorgenommen werden. Wesentlich ist auch, dass der Treiber und der Bieger unabhängig vom Schlittenhub angetrieben sind. Die Bewegungen des Treibers und des Biegers können damit in einfacher Weise und optimal auf die Heftkopffunktionen abgestimmt werden.The task is with a wire stitching machine of the type mentioned solved according to claim 1. In the wire stitching machine according to the invention is a drive for the staple carriage stroke and a separate drive for the stroke of the bender and the stroke of the Driver provided. Both drives can work independently of each other be converted. For example, the staple carriage stroke of about 140 mm for a chain pitch of 14 inches To change about 200 mm for 21 inch chain pitch must therefore only the first drive for the staple carriage stroke switched become. The second drive for the stroke of the bender and the stroke of the driver is not affected. The conversion is therefore structurally much easier and can can also be carried out by a trained operator. It is also essential that the driver and the bender are independent are driven by the carriage stroke. The movements the driver and the bender can thus easily and be optimally matched to the stitching head functions.

Sind die Produkte 11 geheftet, so werden sie einzeln von einer hier nicht gezeigten Auslage erfasst und von der laufenden Doppelsammelkette 6 abgehoben und zur weiteren Bearbeitung beispielsweise einer hier nicht gezeigten Schneidvorrichtung zugeführt. Dem Fachmann sind verschiedene Ausführungen solcher Auslagen bekannt.If the products 11 are stapled, they are separated by one Display not shown here and recorded from the current Double collection chain 6 lifted and for further processing for example a cutting device, not shown here fed. Various designs are known to the person skilled in the art such expenses known.

Der Schlitten 15 mit den beiden Heftköpfen 16 läuft beim Heften mit den kontinuierlich geförderten Produkten 11 mit. Die Produkte 11 werden somit zum Heften nicht angehalten und müssen nachher auch nicht beschleunigt werden. Beim Heften der Produkte 11 führt der Schlitten 15 mit den mitlaufenden Heftköpfen 16 einen Hub in Richtung des Pfeiles 63 aus. Nach dem Heften wird ein entsprechender Hub in Gegenrichtung ausgeführt. Dazu ist ein erster Antrieb 12 vorgesehen, der ein Kurbelrad 65 aufweist, an dem eine Kurbel 13 angelenkt ist. Die Verbindung der Kurbel 13 mit dem Kurbelrad 65 erfolgt hier mit einem exzentrisch gelagerten Kurbelzapfen 13a. Durch Drehen des Kurbelzapfens 13a kann der Hub des Heftschlittens beispielsweise von 140 mm für eine Kettenteilung von 14 Zoll auf einen Hub von 200 mm für eine 21 Zoll Kettenteilung umgestellt werden. Für andere Hübe können im Kurbelrad 65 hier nicht gezeigte Bohrungen vorgesehen sein. Der Antrieb 12 ist ausserhalb eines hier nicht gezeigten ölgeschmierten Getriebekastens angeordnet. Dadurch können Ölverluste entlang der Kurbelstange vermieden werden und es kann kein Papierstaub in das Getriebe des Antriebs 12 eindringen.The carriage 15 with the two stitching heads 16 runs during stitching with the continuously promoted products 11. The Products 11 are therefore not stopped for stapling not accelerated afterwards either. When stapling the The carriage 15 carries products 11 with the running stitching heads 16 a stroke in the direction of arrow 63. After this Stapling is carried out in the opposite direction. A first drive 12 is provided for this purpose Has crank wheel 65 to which a crank 13 is articulated. The crank 13 is connected to the crank wheel 65 here with an eccentrically mounted crank pin 13a. By Rotating the crank pin 13a can increase the stroke of the staple carriage for example of 140 mm for a chain pitch of 14 inches converted to a stroke of 200 mm for a 21 inch chain pitch become. For other strokes, crank wheel 65 can be found here Bores not shown may be provided. The drive 12 is outside of an oil-lubricated gearbox, not shown here arranged. This can cause oil loss along the Crank rod can be avoided and there can be no paper dust in it penetrate the transmission of the drive 12.

Die Kurbel 13 ist mit dem Heftschlitten 15 an einem oberen Ende 13b gelenkig verbunden.The crank 13 is with the tacking carriage 15 at an upper End 13b articulated.

In der Figur 2 ist von der Kurbelstange 13 des ersten Antriebs 12 lediglich das obere Ende 13b gezeigt. Zur Führung des Heftschlittens 15 ist eine Führungsstange 31 vorgesehen, die an ihren beiden Enden 31a jeweils fest mit dem Maschinengestell 29 verbunden ist. Zur Lagerung des Schlittens 15 auf der Führungsstange 31 weist dieser eine Gleitführung mit zwei Kugelbüchsen 36 auf. Mit dieser sind die beiden Heftköpfe 16 über eine verschiebbare Halteplatte 66 fest verbunden. Die Heftköpfe 16 sind an der Halteplatte 66 verschiebbar befestigt.In Figure 2 is of the crank rod 13 of the first drive 12 only the upper end 13b is shown. For guidance of the stitching carriage 15, a guide rod 31 is provided, which are fixed at both ends 31a to the machine frame 29 is connected. For storing the carriage 15 on the guide rod 31 has a sliding guide with two Ball bushings 36. With this, the two stitching heads 16 firmly connected via a displaceable holding plate 66. The Stapling heads 16 are slidably attached to the holding plate 66.

Der durch die Führungsstange 31 und die beiden Kugelbüchsen 36 begrenzt horizontal verschieblich geführte Heftschlitten 15 ist gemäss Figur 5 an seinem unteren Ende mittels einer Rolle 100 am Maschinengestell 29 abgestützt. Am Heftschlitten 15 ist über zwei vertikale Führungsstangen 34 ein Umbiegersupport 101 befestigt. Am unteren Ende jeder Führungsstange 34 ist eine höhenverstellbare Mutter 32 angebracht, an welcher eine vorgespannte Druckfeder 35 abgestützt ist. Die beiden Druckfedern 35 lasten jeweils mit ihrem oberen Ende auf dem Umbiegersupport 101, der bei Dickenvariationen infolge von Selective Binding oder bei überlast durch einen Papierstau nach unten ausweichen kann. Wird ein vorbestimmter Weg überschritten, so schaltet ein am Maschinengestell 29 befestigter, induktiver Schalter 105 die Maschine aus.The through the guide rod 31 and the two ball bushings 36 limited horizontally slidable slides 15 is according to Figure 5 at its lower end by means of a Roller 100 supported on the machine frame 29.

Je dicker das Druckprodukt 11 umso grösser der Weg, auf dem der Umbiegersupport 101 unter der Gegenkraft der Federn 35 nach unten ausweicht. Wie ersichtlich, wird beim Verstellen der Mutter 32 die Höheneinstellung der Umbieger 64 nicht beeinflusst.With a handwheel 76 and an eccentric, not shown here the bending carrier 102 can be adjusted to the product thickness. In so-called selective binding, the same Production of printed products 11 of different thicknesses stapled. For this purpose, the benders 64 are adjusted in height with the handwheel 76 set to the thinnest printed product 11. Thereby constant staple quality is achieved. The thicker that Print product 11, the greater the way in which the bending support 101 under the counterforce of the springs 35 down dodging. As can be seen, when adjusting the mother 32 does not affect the height adjustment of the bender 64.

Die Umbieger 70 sind seitlich auf einer Umbiegerleiste 73 verschiebbar und werden damit auf die Heftköpfe 16 ausgerichtet. An einem Umbiegeträger 102 ist ein Umbiegergestänge 103 gelagert, das mit dem Umbiegeträger 102 in der Höhe verstellt wird. Die Betätigung des Umbiegergestänges 103 erfolgt durch den Schlittenhub über eine am Maschinengestell 29 mit Verbindungsleitern 108 befestigte Kurvenleiste 104 und eine schwenkbare Kurvenrolle 106. Der Umbiegehub ist damit unabhängig von der Dickeneinstellung des Umbiegeträgers 102 und der Einfederung der Parallelführung.The benders 70 are laterally on a bender bar 73 displaceable and are thus aligned with the stitching heads 16. A bending linkage 103 is located on a bending beam 102 stored, which is adjusted in height with the bending beam 102 becomes. The bending linkage 103 is actuated by the carriage stroke via a on the machine frame 29 with connecting conductors 108 attached curve strip 104 and one swiveling cam roller 106. The bending stroke is therefore independent on the thickness setting of the bending beam 102 and the deflection of the parallel guide.

Zum seitlichen Ausrichten der Umbieger 70 auf die Heftköpfe 16 ist gemäss Figur 2 ein sich horizontal erstreckender Träger 71 mit Führungsschlitzen 71a angeordnet. Der Umbieger 70 ist hier aus zeichnerischen Gründen weggelassen. Ein sich ebenfalls horizontal erstreckender Balken 72 dient zum übertragen des Umbiegerhubes auf den Umbieger 70. Der Umbiegerträger 102 ist zum Einstellen der Produktedicke zwischen Umbieger 70 und Heftkopf 16 in seiner Höhe verschiebbar und weist einen plattenförmigen Teil 74 sowie einen fest mit diesem verbundenen und das Handrad 76 aufnehmenden Teil 75 auf. Für die Dickenverstellung ist das Handrad 76 mit einem hier nicht gezeigten Exzenter versehen. Das Umbiegergestänge 103 weist gemäss Figur 5 zwei jeweils gelenkig mit einem Hebel 78 verbundene Stangen 77 auf. Die Übertragung der Bewegung der oben erwähnten Kurvenrolle 106 auf die Hebel 78 erfolgt über eine Welle 107, auf welcher die Hebel 78 festgeklemmt sind.For the lateral alignment of the bender 70 on the stitching heads 16 is, according to FIG. 2, a horizontally extending support 71 with guide slots 71a. The bender 70 is omitted here for drawing reasons. A yourself bar 72, which also extends horizontally, is used for transmission of the bending stroke on the bending arm 70. The bending arm 102 is used to adjust the product thickness between benders 70 and stitching head 16 displaceable in height and has a plate-shaped part 74 and a fixed part with it connected and the handwheel 76 receiving part 75. The handwheel 76 with one is here for the thickness adjustment not shown eccentric. The folding linkage 103 5 has two articulated each with a lever 78 connected rods 77. The transmission of the movement of the The above-mentioned cam roller 106 on the lever 78 takes place via a shaft 107 on which the levers 78 are clamped.

Die beiden Heftköpfe 16 weisen jeweils in bekannter Weise einen Treiber 17 und einen Bieger 18 auf. Der Treiber 17 und der Bieger 18 führen zum Heften jeweils einen Arbeits- und Rückhub aus. Die einzutreibenden Klammern werden jeweils von einer hier nicht gezeigten Drahtspule abgeschnitten. Der Vorgang des Heftens ist dem Fachmann gut bekannt und braucht hier deshalb nicht näher erläutert zu werden.The two stitching heads 16 each have one in a known manner Driver 17 and a bender 18. The driver 17 and the bender 18 each lead to a work and for stapling Return stroke off. The parentheses to be driven in are each from a wire coil, not shown here, cut off. The process stapling is well known to those skilled in the art and needs therefore not to be explained in more detail here.

Für den Arbeits- und Rückhub sind die Treiber 17 in einem Führungsschlitz 21 einer Treiberkulisse 19 gelagert. Die Bieger 18 werden durch eine Kurvenrolle, die in einem Führungsschlitz 22 einer Biegerkulisse 20 eingreift, bewegt. Beide Kulissen 19 und 20 sind an ihren Enden jeweils vertikal verschieblich mittels zwei Führungsleisten 23 an einer Halteplatte 24 gelagert. Die beiden Treiber 16 sind am oberen Ende rückseitig jeweils mit einer Rolle 61 versehen, welche in den Führungsschlitz 21 eingreift (Figur 4). Die Bieger 18 sind ebenfalls mit einer hier nicht gezeigten Rolle versehen, die in den Führungsschlitz 22 eingreifen. Bei den Hubbewegungen des Schlittens 15 können die beiden Heftköpfe geführt in den Führungsschlitten 21 und 22 sich relativ zu den beiden Kulissen 19 und 20 verschieben. Gleichzeitig können durch vertikale Bewegungen der geführten Kulissen 19 und 20 die Arbeitsund Rückhube der Treiber 17 und der Bieger 18 ausgeübt werden. Für diese Bewegungen der Kulissen 19 und 20 ist ein zweiter Antrieb 14 vorgesehen, der gemäss Figur 1 eine Welle 14a aufweist, die über ein Kegelrad 14b mit einem Antriebsrad 14c verbunden ist. Dieses Antriebsrad 14c ist ebenfalls mit der hier nicht gezeiten Hauptantriebswelle verbunden. Die Drehbewegung der Welle 14a wird mit einem Zahnriemen 38 und einem Antriebsrad 37 auf eine Antriebswelle 39 übertragen, die gemäss Figur 2 mit Lagern 28 an zwei Lagerplatten 26 gelagert ist. Diese Lagerplatten 26 sind mit zwei Halteplatten 25 verbunden. Auf der Antriebswelle 39 sind im Abstand zueinander zwei Kurvenscheiben 40 befestigt, die jeweils eine Nutenkurve 41 besitzen, wie die Figur 3a und 4 zeigen.For the working and return stroke, the drivers 17 are in one Guide slot 21 of a driver link 19 mounted. The benders 18 are by a cam roller, which is in a guide slot 22 of a bending link 20 engages, moves. Both Scenes 19 and 20 are vertically displaceable at their ends by means of two guide strips 23 on a holding plate 24 stored. The two drivers 16 are at the top provided on the back with a roller 61, which in the Guide slot 21 engages (Figure 4). The benders are 18 also provided with a role, not shown here, the engage in the guide slot 22. With the lifting movements of the carriage 15, the two stitching heads can be guided in the Guide carriage 21 and 22 are relative to the two scenes Move 19 and 20. At the same time through vertical Movements of the guided scenes 19 and 20 the working and Return stroke of the driver 17 and the bender 18 are exercised. For these movements of the scenes 19 and 20 is a second drive 14 is provided, which according to FIG. 1 is a shaft 14a, which has a bevel gear 14b with a drive wheel 14c is connected. This drive wheel 14c is also with the main drive shaft not tied here. The Rotary movement of the shaft 14a is with a toothed belt 38 and a drive wheel 37 transmitted to a drive shaft 39, which are supported according to FIG. 2 with bearings 28 on two bearing plates 26 is. These bearing plates 26 are with two holding plates 25 connected. On the drive shaft 39 are spaced apart two cams 40 attached, each a groove curve 41, as shown in FIGS. 3a and 4.

Parallel zur Antriebswelle 39 und im Abstand zu dieser ist an den Lagerplatten 26 mit Drehlagern 27 eine weitere Welle 43 gelagert, die koaxial eine Hohlwelle 51 durchgreift, die mit Drehlagern 55 und 56 an zwei weiteren Lagerplatten 53 und 54 drehbar gelagert ist. Mit der Welle 43 sind zwei Treiberhebel 47 und 48 drehfest verbunden. Weiter ist auf der Welle 43 mit einem Lager 44 ein Kurvenhebel 42 drehbar gelagert. Wie die Figur 3b zeigt, ist an diesem Kurbelkurvenhebel 42 eine Rolle 67 angebracht, die in die Nutenkurve 41 eingreift. Beim Drehen der Kurvenscheibe 40 wird der Kurvenhebel 42 um die Welle 43 entsprechend dem Verlauf der Nutenkurve 41 verschwenkt. Am zweiarmigen Kurvenhebel 42 ist gegenüberliegend zur Rolle 67 eine pneumatisch betätigbare Kupplung 45 angebracht, die mit einem Kupplungsbolzen 46 in eine konische Bohrung 68 des Treiberhebels 47 eingreift. Der Kupplungsbolzen 46 bildet einen Kolben und kann über eine hier nicht gezeigte pneumatische Leitung in Figur 3a nach rechts bewegt werden, wodurch die Kupplung gelöst wird. Im gezeigten gekuppelten Zustand wird der Treiberhebel 47 formschlüssig mit dem Kurbelhebel 42 verschwenkt. Da nun der Treiberhebel 47 drehfest mit der Welle 43 verbunden ist, wird gleichzeitig auch der weitere Treiberhebel 48 gleichsinnig verschwenkt.Parallel to and at a distance from the drive shaft 39 is on the bearing plates 26 with pivot bearings 27 a further shaft 43 stored, which passes through a hollow shaft 51 coaxially Pivots 55 and 56 on two further bearing plates 53 and 54 is rotatably mounted. With the shaft 43 are two driver levers 47 and 48 rotatably connected. Next is on shaft 43 with a bearing 44 a cam lever 42 rotatably mounted. How 3b shows, is on this crank cam lever 42 Roller 67 attached, which engages in the groove curve 41. At the Turning the cam 40, the cam lever 42 is about Shaft 43 pivoted according to the course of the groove curve 41. On the two-armed cam lever 42 is opposite a pneumatically actuable coupling 45 is attached to the roller 67, with a coupling pin 46 in a conical Bore 68 of the driver lever 47 engages. The coupling pin 46 forms a piston and can via a not shown here pneumatic line in Figure 3a moved to the right be, whereby the clutch is released. Coupled shown Condition the driver lever 47 is form-fitting with the Crank lever 42 pivoted. Since the driver lever 47 is now non-rotatable is connected to the shaft 43, at the same time the other driver lever 48 pivoted in the same direction.

Wie die Figur 4 zeigt, besitzt der Treiberhebel 47 eine Zahnung 59, welche mit der Zahnung einer Zahnstange 60 kämmt. Diese Zahnstange 60 ist rückseitig fest mit der Treiberkulisse 19 verbunden. Der Treiberhebel 48 ist in gleicher Weise mit einer weiteren Zahnstange 60 in Eingriff. Bei einer Drehbewegung der Welle 43 wird somit über die beiden Treiberhebel 47, 48 die Kulisse 19 zwangsweise vertikal bewegt. Die Nutenkurve 41 ist nun so ausgeführt, dass die Treiberkulisse 19 in einem oberen Umkehrpunkt für eine bestimmmte Zeit zum Stillstand kommt. Während eines solchen Stillstandes kann die Kupplung 45 pneumatisch betätigt werden.As FIG. 4 shows, the driver lever 47 has teeth 59, which meshes with the teeth of a rack 60. This rack 60 is fixed on the back with the driver link 19 connected. The driver lever 48 is in the same way engages with another rack 60. With a rotary movement the shaft 43 is thus via the two driver levers 47, 48 the backdrop 19 is forced to move vertically. The groove curve 41 is now designed so that the driver link 19 in an upper reversal point for a certain time to a standstill comes. During such a standstill, the Clutch 45 can be operated pneumatically.

Die Biegerkulisse 20 wird ähnlich wie die Treiberkulisse 19 vertikal bewegt. Hierzu wird gemäss Figur 3a der Kurvenhebel 49 bewegt, der drehbar auf der Hohlwelle 51 gelagert ist und mittels der Kupplung 45 diese Schwenkbewegung auf einen Biegerhebel 50 überträgt. Dieser Biegerhebel 50 ist drehfest mit der Hohlwelle 51 verbunden. Die Schwenkbewegung des Biegerhebels 50 wird damit auf einen weiteren Biegerhebel 52 übertragen, der ebenfalls mit der Hohlwelle 51 verbunden ist. Die beiden Biegerhebel 50 und 52 sind in gleicher Weise wie die Treiberhebel 47 und 48 über Zahnungen mit der Biegerkulisse 20 in Eingriff. Beim Drehen der Hohlachse 51 wird entsprechend die Biegerkulisse 20 vertikal bewegt. Auch die Biegerkulisse 20 ist so gesteuert, dass sie in einem oberen Umkehrpunkt für eine bestimmmte Zeit zum Stillstand kommt, in welcher die Kupplung 45 pneumatisch betätigt werden kann. Gemäss Figur 4 ist eine Zugfeder 62 vorgesehen, die am Treiberhebel 47 angreift. Im ausgekuppelten Zustand wird der Treiberhebel 47 über diese Zugfeder 62 im oberen Umlenkpunkt an einen Anschlag 58 gezogen. Für den Biegerhebel 50 ist eine weitere hier nicht gezeigte Zugfeder vorgesehen.The bending link 20 becomes similar to the driver link 19 moved vertically. For this purpose, according to FIG. 3a, the cam lever 49 moves, which is rotatably mounted on the hollow shaft 51 and by means of the coupling 45 this pivoting movement on a bending lever 50 transmits. This bending lever 50 is non-rotatable with the hollow shaft 51 connected. The pivoting movement of the bending lever 50 is thus transferred to a further bending lever 52, which is also connected to the hollow shaft 51. The both bending levers 50 and 52 are in the same way as that Driver levers 47 and 48 over serrations with the bending link 20 engaged. When turning the hollow axis 51 is accordingly the bending link 20 moves vertically. Even the bending backdrop 20 is controlled to be at an upper turning point comes to a standstill for a certain time, in which the clutch 45 can be actuated pneumatically. According to Figure 4 is a tension spring 62 is provided on the driver lever 47 attacks. When disengaged, the driver lever 47 via this tension spring 62 in the upper deflection point to a stop 58 drawn. Another is for the bending lever 50 Tension spring not shown here is provided.

Die vertikalen Bewegungen der Treiberkulisse 19 und der Biegerkulisse 20 werden zwangsweise an die Treiber 17 und 18 übertragen. Der Arbeitshub dient zum Formen und Eintreiben der Heftklammer und der Rückhub zum Vorschieben und Abschneiden des Heftdrahtes. Arbeits- und Rückhub erfolgen zwangsläufig. Diese Bewegungen bilden den Arbeits- und Rückhub und werden in jeder Position der Heftköpfe 16 in gleicher Weise ausgeübt. Der Heftvorgang kann somit beim Mitlaufen der beiden Heftköpfe 16 ausgeführt werden. Wesentlich ist nun, dass der Antrieb 14 für den Arbeits- und Rückhub der Treiber 17 und der Bieger 18 unabhängig zum Antrieb 12 verstellbar ist. Die Kurbel 13 kann somit umgestellt werden, ohne dass hierbei der Heftmechanismus der beiden Heftköpfe 16 verstellt wird. Umgekehrt kann der Heftmechanismus verstellt werden, ohne dass hierbei die Hubbewegung des Schlittens 15 beeinflusst wird. Wesentlich ist zudem, dass die Heftköpfe 16 auch zum Heften von dicken und harten Produkten eingesetzt werden können. Es ist zudem in einfacher Weise möglich, die Kurvenräder 40 durch Räder mit einer anderen Nutenkurve zu ersetzen, um hierbei zur Anpassung an besonders dicke und bauschige Produkte 11 die entsprechenden vertikalen Bewegungen der Treiber 17 und 18 anzupassen. Der horizontale Hub des Heftschlittens 15 wird dadurch nicht beeinflusst.The vertical movements of the driver link 19 and the bending link 20 are forced to the drivers 17 and 18 transfer. The working stroke is used for shaping and driving in the staple and the return stroke for feeding and cutting of the stitching wire. Working and return stroke are inevitable. These movements form the working and return stroke and are in any position of the stitching heads 16 in the same way exercised. The stapling process can thus take place when the two run along Stapling heads 16 are executed. It is now essential that the drive 14 for the working and return stroke of the driver 17th and the bender 18 is adjustable independently of the drive 12. The crank 13 can thus be switched over without this the stitching mechanism of the two stitching heads 16 is adjusted. Conversely, the stapling mechanism can be adjusted without that this affects the stroke movement of the carriage 15 becomes. It is also essential that the stitching heads 16 also for Stapling thick and hard products can be used. It is also possible in a simple way, the cam wheels 40 to be replaced by wheels with a different groove curve here to adapt to particularly thick and bulky products 11 the corresponding vertical movements of the drivers 17 and 18 to adapt. The horizontal stroke of the staple carriage 15 is not affected by this.
