Description

Die Erfindung bezieht sich auf eine Schneideinrichtung für eine Formularbahn die auf einem Druckkonfwagen eines Druckers angeordnet ist mit einem an einem schwenkbaren Hebel befestigten Schneidrad das durch die Bewegung des Druckkopfwagens antriebbar und an eine ortsteste Gegenschneide anstellbar ist wobei das Schneidrad durch eine Steuereinrichtung aus einer unwirksamen angehobenen und zurückgezogenen Stellung in eine in Schneidlage abgesenkt und vorgeschobene Stellung gebracht wird und das Schneidrad in der Schneidstellung durch eine Feder in Anlage an der Gegenschneide gehalten wird.The invention relates to a cutting device for a form web which is arranged on a printing carriage of a printer with a cutting wheel fastened to a pivotable lever which can be driven by the movement of the printing head carriage and can be adjusted to a stationary counter knife, the cutting wheel being raised from an ineffective by a control device and retracted position is lowered into a cutting position and advanced position and the cutting wheel is held in the cutting position by a spring in contact with the shear bar.

Beispielsweise in dem DE-GM 78 12 759 ist eine Schneidvorrichtung für Formularbahnen beschrieben. Durch ein Steuerteil wird ein Schneidrad aus einer zurückgezogenen, unwirksamen Stellung, in der normalerweise der Druck erfolgt, in eine vorgeschobene, abgesenkte Stellung geschoben, in der der Schneidvorgang durchgeführt wird. Die Schneidvorrichtung ist mit der Druckeinheit verbunden und die Schneidbewegung des Schneidrades wird aus der Bewegung des Druckkontschlittens relativ zur Druckunterlage abgeleitet. Bei der bekannten Anordnung wird das Steuerteil einerseits durch gehäusefeste Anschläge aus der unwirksamen in die wirksame Stellung gesteuert, gleichzeitig sind an der Druckunterlage noch Anschlaufschrägen oder dergl. vorhanden, durch die sichergestellt wird, daß das Schneidrad in die Anlageposition zu der Gegenschneide gebracht wird. Die Anordnung besonderer, gehäusefester Anschläge für das Betätigen des Steuerteiles und besonderer Anlaufschrägen für das Wirksammachen des Schneidrades in der Schneidstellung erfordert einen erheblichen Aufwand.For example, a cutting device for form webs is described in DE-GM 78 12 759. A control part pushes a cutting wheel from a retracted, ineffective position, in which the pressure is normally applied, into an advanced, lowered position, in which the cutting process is carried out. The cutting device is connected to the printing unit and the cutting movement of the cutting wheel is derived from the movement of the printing carriage relative to the printing base. In the known arrangement, the control part is controlled on the one hand by stops fixed to the housing from the ineffective into the effective position, at the same time there are lead-in slopes or the like on the printing pad which ensure that the cutting wheel is brought into the contact position with the shear bar. The arrangement of special, fixed stops for actuating the control part and special bevels for making the cutting wheel effective in the cutting position requires considerable effort.

Die eingangs bezeichnete Schneideinrichtung ist aus der FR-A-2 389 300 bekannt. Hiernach umfaßt der Stand der Technik eine Schneideinrichtung, wobei das Schneidrad durch eine Steuereinrichtung aus einer unwirksamen, angehobenen und zurückgezogenen Stellung in eine in Schneidlage gesenkte und vorgeschobene Stellung gebracht wird und das Schneidrad in der Schneidstellung durch eine Feder in Anlage an der Gegenschneide gehalten wird. Eine solche Lösung erfordert neben der Aufhängung des Schneidrades an einem schwenkbaren Hebel einen mehrarmigen Steuerhebel, der einerseits mit dem schwenkbaren Hebel und andererseits mit einer in Bewegungsrichtung verlaufenden Steuerstange zusammenwirkt. Nachteilig ist hier aber auch, daß die bekannte Einrichtung relativ kompliziert ist und erheblichen Platzbedarf erfordert. Der dort beanspruchte Platz steht in vielen Druckern nicht zur Verfügung.The cutting device referred to at the outset is known from FR-A-2 389 300. According to this, the prior art comprises a cutting device, the cutting wheel being brought by a control device from an ineffective, raised and retracted position into a position lowered and advanced into the cutting position, and the cutting wheel is held in the cutting position by a spring in contact with the shear bar. In addition to the suspension of the cutting wheel on a pivotable lever, such a solution requires a multi-armed control lever which interacts on the one hand with the pivotable lever and on the other hand with a control rod extending in the direction of movement. However, it is also disadvantageous here that the known device is relatively complicated and requires considerable space. The space used there is not available in many printers.

Demgegenüber ist es eine Aufgabe der Erfindung, die Steuereinrichtung für das Verbringen des Schneidrades aus der unwirksamen, angehobenen Stellung in die wirksame Schneidstellung zu verbessern, insbesondere zu vereinfachen. Gleichzeitig ist es Aufgabe der Erfindung, den Platzbedarf für die Umschaltung des Schneidrades zu verringern, um dadurch die Druckbreite zu verbessern.In contrast, it is an object of the invention, the control device for moving the cutting wheel from the ineffective, raised position into the effective cutting position to improve, in particular to simplify. At the same time, it is an object of the invention to reduce the space required for switching the cutting wheel in order to improve the printing width.

Eine weitere Aufgabenstellung ergibt sich daraus, daß bei der bekannten Anordnung die Haltevorrichtung für die zu schneidenden Formularbahnen mit dem Schneidrad direkt verbunden ist. Das führt dazu, daß ein nur punktförmiges Festhalten des Formulares während des Schneidvorganges dort erfolgt, wo geschnitten wird, jedoch nicht während des Anschneidens. Dadurch kann nicht ausgeschlossen werden, daß die Formularbahnen sich am Beginn und am Ende des Schneidvorganges leicht verschieben, so daß keine geraden Schnittkanten entstehen.Another task results from the fact that in the known arrangement the holding device for the form webs to be cut is directly connected to the cutting wheel. This leads to the fact that the form is only held in a punctiform manner during the cutting process where the cutting takes place, but not during the cutting. This cannot rule out that the form webs shift slightly at the beginning and at the end of the cutting process, so that there are no straight cutting edges.

Demgegenüber stellt sich die Erfindung die zusätzliche Aufgabe, die Formularbahnen so zu halten, daß ein Ausweichen der Formularbahnen am Beginn und am Ende des Schneidvorganges vermieden wird.In contrast, the invention has the additional object of holding the form webs in such a way that avoidance of the form webs at the beginning and at the end of the cutting process is avoided.

Die Erfindung ist dadurch gekennzeichnet, daß die Steuereinrichtung aus einem Schieber mit zumindest zwie Kurvenführungen besteht, wobei die erste Kurven führung das Schneidrad aus der angehobenen in die abgesenkte Stellung bringt, und die zweite Kurvenführung das Schneidrad aus der zurückgezogenen in die vorgeschobene Stellung bringt und anschließend durch die Kraft der genannten Feder freigibt. Der Schieber erhält seine Steuerbewegung durch Zusammenwirken mit den die Bewegung des Druckschlittens begrenzenden, seitlichen Begrenzungen.The invention is characterized in that the control device consists of a slide with at least two cam guides, the first cam guide bringing the cutting wheel from the raised to the lowered position, and the second cam guide bringing the cutting wheel from the retracted to the advanced position and then released by the force of the spring mentioned. The slide receives its control movement through interaction with the lateral limits which limit the movement of the pressure carriage.

Die Verwendung des Schiebers mit den Kurvenführungen als Steuervorrichtung hat den Vorteil, daß ein leichtgängiges Verschieben des Schneidrades möglich ist und daß dieses letztere nur unter der geringen Kraft einer relativ schwachen Feder in Anlage an der Gegenschneide gehalten wird. Durch das leicht federnde Anliegen des Schneidrades werden etwaige Toleranzen in der Schlittenführung ausgeglichen und der Verschleiß des Schneidrades verringert.The use of the slider with the cam guides as a control device has the advantage that the cutting wheel can be moved easily and that this the latter is held against the shear bar only under the low force of a relatively weak spring. The slightly resilient abutment of the cutting wheel compensates for any tolerances in the slide guide and reduces wear on the cutting wheel.

Gemäß der Erfindung ist eine zweite Kurvenführung vorgesehen, die dem Schneidrad seine Bewegung aus der zurückgezogenen in die vorgeschobene Stellung erteilt, während über eine erste Kurvenführung das Schneidrad gehoben und gesenkt wird, wobei die Bewegungen des Schneidrades sich durch die erste und zweite Kurvenführung so überlagern, daß das Schneidrad bei seiner Bewegung um die scharfe Gegenschneide an der Druckunterlage herumgeführt wird. Für das Halten der Formularbahnen wirkt die Steuereinrichtung unabhängig von dem Schneidrad auf Halterollen ein, die beidseits des Schneidrades angeordnet sind. Die Halterollen sind vorzugsweise auf einem Waagehebel angeordnet, der sich selbsttätig in Halteposition einstellt.According to the invention, a second cam guide is provided which gives the cutting wheel its movement from the retracted into the advanced position, while the cutting wheel is raised and lowered via a first cam guide, the movements of the cutting wheel being superimposed by the first and second cam guides, that the cutting wheel is guided around the sharp shearbar on the printing pad as it moves. To hold the form webs, the control device acts independently of the cutting wheel on holding rollers which are arranged on both sides of the cutting wheel. The holding rollers are preferably arranged on a scale lever which adjusts itself automatically in the holding position.

Wie FIG. 1 erkennen läßt, sind zwischen zwei seitlichen Begrenzungsplatinen 1 und 2 zwei Führungsachsen 3 und 4 für einen Druckwagen 5 angeordnet. Auf dem Druckwagen 5 befindet sich der Druckkopf 6, der mit seinem Mundstück 7 unmittelbar vor der Druckunterlage 8 steht und auf der Formularbahn 9 druckt. Die Schneidvorrichtung 10 ist am Druckwagen 5 so befestigt, daß das Schneidrad 11 mit einer Schneide 20 - siehe auch FIG. 6 - an der Druckunterlage 8 zusammenwirken kann. Festgelegt zwischen den seitlichen Begrenzungsplatinen 1 und 2 ist noch die Farbbandkassette, die aus zwei Teilen, 13a und 13b, besteht, zwischen denen das Farbband 14 vor der Druckunterlage 8 gespannt ist. Das Farbband 14 wird zu seiner Führung einerseits um die Führungsbolzen 15 und 16 herumgeführt, andererseits liegt es vor dem Mundstück 7, d. h. vor den Öffnungen, durch die die Drucknadeln des Druckwerkes 6 austreten.As FIG. 1 reveals two guide axes 3 and 4 for a printing carriage 5 are arranged between two lateral boundary plates 1 and 2. On the print carriage 5 is the print head 6, which stands with its mouthpiece 7 directly in front of the printing pad 8 and prints on the form web 9. The cutting device 10 is attached to the printing carriage 5 so that the cutting wheel 11 with a cutting edge 20 - see also FIG. 6 - can cooperate on the printing pad 8. The ink ribbon cassette, which consists of two parts, 13a and 13b, between which the ink ribbon 14 is stretched in front of the printing pad 8 is also fixed between the lateral boundary boards 1 and 2. The ribbon 14 is guided to guide it on the one hand around the guide bolts 15 and 16, on the other hand, it lies in front of the mouthpiece 7, i. H. in front of the openings through which the printing needles of the printing unit 6 emerge.

Die Einzelheiten der Schneideinrichtung 10 sollen nun unter besonderer Bezugnahme auf die FIG. 2, 3, 4 und 5 im einzelnen beschrieben werden. Dabei zeigt die FIG. 2 die Schneideinrichtung in der Stellung, in der das Schneidrad 11 in seiner unwirksamen Stellung ist, in der also der Druckkopf 6, 7 auf die Formularbahnen 9 einwirkt, die auf der Druckunterlage 8 zugeführt werden. Wie man insbesondere aus FIG. 6 erkennen kann, ist an der Vorderseite der Druckunterlage 8 eine Gegenschneide 20 angebracht, die mit dem Schneidrad 11 zusammenwirkt und das Abscheren der Formularbahn 9 bei entsprechender Ansteuerung bewirkt. FIG. 3 zeigt andererseits die Schneideinrichtung 10 in der wirksamen Stellung, d.h. in der Stellung, in der das Schneidrad 11 mit der Gegenschneide 20 zusammenwirkt, um das Abscheren einzelner Abschnitte der Formularbahn 9 zu bewirken. Ein Tragteil 21 trägt die gesamten Teile der Schneideinrichtung 10. Wie FIG. 5 erkennen läßt, ist das Tragteil 21 ein bügelförmiges, abgewinkeltes Teil, welches vorne und hinten abgewinkelte Lappen 22, 23, 24 und 45 besitzt. Auch seitlich ist das Tragteil 21 mit Abwinklungen 25 und 26 versehen, die die Aufgabe haben, die verschiedenen aktiven Teile der Schneideinrichtung zu lagern und zu führen.The details of the cutting device 10 will now be described with particular reference to FIG. 2, 3, 4 and 5 will be described in detail. The FIG. 2, the cutting device in the position in which the cutting wheel 11 is in its inactive position, in which the print head 6, 7 thus acts on the form webs 9, which are fed on the printing pad 8. As can be seen in particular from FIG. 6 recognize can, a shear bar 20 is attached to the front of the printing pad 8, which cooperates with the cutting wheel 11 and causes the form web 9 to be sheared off with appropriate control. FIG. 3, on the other hand, shows the cutting device 10 in the active position, ie in the position in which the cutting wheel 11 interacts with the counter cutting edge 20 in order to cause individual sections of the form web 9 to be sheared off. A support member 21 supports the entire parts of the cutting device 10. As FIG. 5 shows, the support member 21 is a bow-shaped, angled part, which has angled tabs 22, 23, 24 and 45 at the front and rear. Laterally, the support member 21 is provided with bends 25 and 26, which have the task of storing and guiding the various active parts of the cutting device.

Die erfindungsgemäße Steuereinrichtung umfaßt einen Schieber 28 der mit seinen beiden Enden in den abgewinkelten Lappen 25, 26 des Tragteils 21 gehalten und geführt ist. Der Schieber 28 hat zwei Anschlagwülste 29 und 30, die seine Verschiebebewegung begrenzen. Mit seinen beiden Enden 31 und 32 stößt der Schieber 28 an die seitlichen Begrenzung splatinen 1 und 2 der Bewegung des Druckwagens 5, wodurch das Schneidrad 11 in die wirksame bzw. unwirksame Stellung verstellt wird.The control device according to the invention comprises a slide 28 which is held and guided with its two ends in the angled tabs 25, 26 of the supporting part 21. The slide 28 has two stop beads 29 and 30 which limit its displacement movement. With its two ends 31 and 32, the slider 28 abuts the lateral boundary splatinen 1 and 2 of the movement of the printing carriage 5, whereby the cutting wheel 11 is adjusted into the effective or ineffective position.

Der Schieber 28 hat eine Durchdringung 33, eine Kurvenführung 34, eine Durchdringung 35 und eine dritte Kurvenführung 36. Die Durchdringung 33 und die Kurvenführung 34 dienen der Steuerung des Schneidrades 11, die Kurvenführung 36 der Steuerung des Kalterollensatzes 37. Das Schneidrad 11 ist mittels eines Bolzens 38 auf einem Hebel 39 drehbar gelagert. Der Hebel 39 ist mit einer Achse 40 verbunden, die in den abgewinkelten Lappen 22 und 24 des Halteteiles 21 drehbar und axial verschiebbar gelagert ist. Eine Feder 41 wirkt so auf die Achse 40, auf den Hebel 39 und damit auf das Schneidrad 11 ein, daß in der wirksamen Stellung das Schneidrad 11 an der Gegenschneide 20 elastisch anliegt, wie dies beispielsweise die FIG. 6 zeigt. Der Schieber 28 ist im Bereich der Durchdringung 33 mit einer Abwinklung 42 versehen, wobei an der Achse 40 ein Kurvenfolger 43 angeordnet ist, wie sich dies insbesondere aus FIG. 4 ergibt. Die Teile 33, 42, 43 zusammen bilden die zweite Kurvenführung, die dem Vor- und Zurückverschieben des Schneidrades 11 dient. Wenn der Schieber 28 beispielsweise in FIG. 4 von links nach rechts verschoben wird, dann folgt die Achse 40 über den Kurvenfolger 43 und die Abwinklung 42 in dem Schieber 28 dieser Bewegung, so daß das Schneidrad 11 aus einer zurückgezogenen, unwirksamen Stellung in eine vorgeschobene, wirksame Stellung verschoben wird. Hier sei vermerkt, daß, wie aus der FIG. 4 ersichtlich, der Kurvenfolger 43 nicht an der Kurvenführung 33 des Schiebers 28 anliegt, sondern federnd durch die Feder 41, die mit dem Hebel 39 verbunden ist, an die Gegenschneide 20 angedrückt wird. Wird dagegen der Schieber 28 in FIG. 4 von rechts nach links verschoben, dann bewirkt die Kurvenführung 33 des Schiebers 28 mit ihrer Abwinklung 42 und dem Kurvenfolger 43 an der Achse 40 ein Zurückziehen des Schneidrades 11, so daß dieses außer Wirklage mit der Gegenschneide 20 geschoben wird. Bei der Feder 41 handelt es sich um eine relativ schwache Feder, wodurch der Verschleiß des Schneidrades 11 gemindert wird und Toleranzen in der Druckunterlage ausgeglichen werden.The slider 28 has a penetration 33, a curve guide 34, a penetration 35 and a third curve guide 36. The penetration 33 and the curve guide 34 serve to control the cutting wheel 11, the curve guide 36 to control the cold roller set 37. The cutting wheel 11 is by means of a Bolt 38 rotatably mounted on a lever 39. The lever 39 is connected to an axis 40 which is rotatably and axially displaceably mounted in the angled tabs 22 and 24 of the holding part 21. A spring 41 acts on the axis 40, on the lever 39 and thus on the cutting wheel 11 in such a way that the cutting wheel 11 rests elastically on the shearbar 20 in the active position, as is shown, for example, in FIG. 6 shows. The slider 28 is provided with a bend 42 in the area of the penetration 33, a curve follower 43 being arranged on the axis 40, as can be seen in particular from FIG. 4 results. The parts 33, 42, 43 together form the second curve guide, which serves to move the cutting wheel 11 back and forth. For example, if slider 28 is shown in FIG. 4 is shifted from left to right, then the axis 40 follows the cam follower 43 and the bend 42 in the slide 28 of this movement, so that the cutting wheel 11 is moved from a retracted, ineffective position to an advanced, effective position. It should be noted here that, as shown in FIG. 4 can be seen that the cam follower 43 does not abut the cam guide 33 of the slide 28, but is pressed resiliently by the spring 41, which is connected to the lever 39, against the shear bar 20. However, if the slide 28 in FIG. 4 shifted from right to left, then the curve guide 33 of the slider 28 with its bend 42 and the curve follower 43 on the axis 40 causes the cutting wheel 11 to be retracted so that it is pushed out of action with the shear bar 20. The spring 41 is a relatively weak spring, as a result of which the wear of the cutting wheel 11 is reduced and tolerances in the printing pad are compensated for.

Zusätzlich zu der zweiten Kurvenführung 33, 42, 43 ist noch die erste Kurvenführung 34 vorgesehen, in die der Bolzen 38 an dem Schneidrad 11 eingreift. Die Form der Kurvenführung 34 gemäß FIG. 5 läßt erkennen, daß das Schneidrad 11 durch den Schieber 28 auch gehoben und gesenkt wird. Die Kurvenführung 33 mit der Abwinklung 42 hat also die Funktion, das Schneidrad 11 vor und zurück zu verschieben, während die Kurvenführung 34 die Funktion hat, das Schneidrad 11 zu heben und zu senken. In der vorgeschobenen, abgesenkten Stellung ist das Schneidrad 11 wirksam, in der zurückgezogenen, angehobenen Stellung ist das Schneidrad 11 unwirksam.In addition to the second cam guide 33, 42, 43, the first cam guide 34 is also provided, in which the bolt 38 engages on the cutting wheel 11. The shape of the curve guide 34 according to FIG. 5 shows that the cutting wheel 11 is also raised and lowered by the slider 28. The curve guide 33 with the bend 42 therefore has the function of moving the cutting wheel 11 back and forth while the curve guide 34 has the function of raising and lowering the cutting wheel 11. In the advanced, lowered position, the cutting wheel 11 is effective, in the retracted, raised position, the cutting wheel 11 is ineffective.

Die Steuereinrichtung, bestehend aus dem Schieber 28, steuert aber nicht nur das Heben und Senken und Vor- und Zurückverschieben des Schneidrades 11 in die und aus der Schneidstellung, sondern es steuert auch eine Haltevorrichtung 37, die die Funktion hat, die Formularbahnen 9 vor und hinter dem Schneidrad 11 zu halten und die unabhängig von dem Schneidrad 11 angesteuert wird. Zu diesem Zwecke ist der Schieber 28 mit einer weiteren Durchdringung 35 und einer Kurvenführung 36 versehen. Ein Steuerhebel 44 ist zwischen dem abgewinkelten Lappen 23 und einem weiteren abgewinkelten Lappen 45 des Halteteiles 21 auf einer Achse 46 gelagert. Eine Feder 47 beeinflußt den Steuerhebel 44 in FIG. 5 im Gegenuhrzeigersinne. Es sei darauf hingewiesen, daß die Durchdringung 35 im Schieber 28 von der Welle 46 lediglich durchdrungen wird, wobei aber keinerlei Steuerungsfunktion auf den Hebel 44 ausgeübt wird. Die Steuerungsfunktion wird vielmehr von der Kurvenführung 36 ausgeübt, die dafür sorgt, daß der Steuerhebel 44 einen Waagehebel 48 aus einer unwirksamen Stellung, beispielsweise gemäß FIG. 2, in eine wirksame Stellung gemäß FIG. 3 verschwenken kann. Der Waagehebel 48 ist auf einem Bolzen 49 an dem Steuerhebel 44 schwenkbar gelagert und trägt je zwei vordere und hintere Halterollen 50, 51, 52 und 53. Es ist darauf hinzuweisen, daß die Achse 38 des Schneidrades 11 koaxial ist mit dem Lagerbolzen 49 des Waagehebels 48. Dadurch bedingt sind die beiden Halterollen 50, 51 einerseits der Schneidlage, die beiden Halterollen 52 und 53 andererseits der Schneidlage der Schneidrolle 11 angeordnet. Durch die von dem Schneidrad unabhängige Ansteuerung der Halterollen 50 bis 53 über den Schieber 28 und die Kurvenführung 36 wird sichergestellt, daß beide Elemente unabhängig voneinander elastisch auf dem Schneidbalken bzw. auf der Druckunterlage 8 aufliegen können. Gleichzeitig wird erreicht, daß die Formularbahnen 9 bereits vor Beginn und noch nach Beendigung des Schneidvorganges von den beiden Halterollen 50, 51 bzw. 52, 53 gehalten werden. Um die Auflage der beiden Halterollen 50, 51 einerseits und 52, 53 andererseits zu verbessern, sind die inneren Rollen 51, 52 mit einer elastischeren Auflage versehen als die äußeren Rollen 50, 53. Auf diese Art und Weise wird sichergestellt, daß am Beginn und am Ende des Schneidvorganges, also des Zusammenwirkens zwischen dem Schneidrad 11 und der Gegenschneide 20 keine Verschiebung der Formularbahnen erfolgen kann, so daß immer ein sauberer, rechteckig zu den Begrenzungskanten erfolgender Schnitt gewährleistet ist.The control device, consisting of the slide 28, not only controls the lifting and lowering and moving back and forth of the cutting wheel 11 into and out of the cutting position, but also controls a holding device 37, which has the function of the form webs 9 in front and to keep behind the cutting wheel 11 and which is controlled independently of the cutting wheel 11. For this purpose, the slide 28 is provided with a further penetration 35 and a curve guide 36. A control lever 44 is mounted between the angled tab 23 and a further angled tab 45 of the holding part 21 on an axis 46. A spring 47 influences the control lever 44 in FIG. 5 counterclockwise. It should be noted that the penetration 35 in the slide 28 is only penetrated by the shaft 46, but no control function is exerted on the lever 44. Rather, the control function is performed by the cam guide 36, which ensures that the control lever 44 moves a balance lever 48 from an inactive position, for example according to FIG. 2, in an effective position according to FIG. 3 can pivot. The balance lever 48 is pivotally mounted on a pin 49 on the control lever 44 and carries two front and rear holding rollers 50, 51, 52 and 53. It should be noted that the axis 38 of the cutting wheel 11 is coaxial with the bearing pin 49 of the balance lever 48. As a result, the two holding rollers 50, 51 on the one hand the cutting position, the two holding rollers 52 and 53 on the other hand the cutting position of the cutting roller 11 are arranged. The control of the holding rollers 50 to 53 via the slide 28 and the cam guide 36, which is independent of the cutting wheel, ensures that that both elements can rest resiliently independently of one another on the cutting bar or on the printing pad 8. At the same time it is achieved that the form webs 9 are held by the two holding rollers 50, 51 and 52, 53 even before the start and after the cutting process has ended. In order to improve the support of the two holding rollers 50, 51 on the one hand and 52, 53 on the other hand, the inner rollers 51, 52 are provided with a more elastic support than the outer rollers 50, 53. In this way it is ensured that at the beginning and at the end of the cutting process, that is to say the interaction between the cutting wheel 11 and the shear bar 20, the form webs cannot be shifted, so that a clean cut which is rectangular to the boundary edges is always ensured.

Den gerade vor sich gehenden Schneidvorgang zeigt FIG. 6 in einer Schnittdarstellung. Man erkennt, daß das Schneidrad 11 nur unter dem sehr leichten Zug der Feder 41 an der Schneidkante der Gegenschneide 20 anliegt.FIG. 6 in a sectional view. It can be seen that the cutting wheel 11 only bears against the cutting edge of the shear bar 20 under the very slight pull of the spring 41.

FIG. 7 zeigt in vergrößerter Darstellung die Bewegung des Schneidrades 11 aus der angehobenen, zurückgezogenen Stellung gemäß FIG. 2 in die wirksame, abgesenkte Stellung. Die gestrichelte Linie zeigt, daß das Schneidrad 11 durch die beiden Kurvenführungen 33 und 34 vorgeschoben und abgesenkt wird. Für die Durchführung der Bewegung sind keinerlei zusätzliche Anlaufschrägen oder Schaltbolzen an dem Drucker selbst erforderlich. Das Umschalten erfolgt vielmehr lediglich durch Zusammenwirken der beiden Enden 31 und 32 des Schiebers 28 mit den beiden seitlichen Begrenzungsplatinen 1 und 2. Soll nicht geschnitten werden, so muß lediglich die Steuerung des Druckerschlittens 5 so erfolgen, daß die Bewegungsumkehr vor Erreichen der Begrenzungsplatinen 1 und 2 erfolgt.FIG. 7 shows in an enlarged view the movement of the cutting wheel 11 from the raised, retracted position according to FIG. 2 in the effective, lowered position. The dashed line shows that the cutting wheel 11 is advanced and lowered by the two cam guides 33 and 34. No additional bevels or switching pins on the printer itself are required to carry out the movement. Rather, the switching takes place only by the interaction of the two ends 31 and 32 of the slide 28 with the two lateral limiting boards 1 and 2. If it is not to be cut, only the control of the printer carriage 5 must take place in such a way that the movement reversal before reaching the limiting boards 1 and 2 is done.
