VORRICHTUNG AN EINER KANTENANLEIMMASCHINE ZUM SCHNEIDEN DES KANTENMATERIALS AN DURCHLAUFENDEN WERKSTÜCKENDEVICE ON AN EDGE BANDING MACHINE FOR CUTTING THE EDGE MATERIAL ON CONTINUOUS WORKPIECES
Technisches GebietTechnical field
Die Erfindung bezieht sich auf eine Vorrichtung an einer Maschine oder einer Maschinenstation zum Aufbringen eines streifen- oder bandförmigen Kantenmaterials und zum Schneiden dieses Kantenmaterials, der im Gattungsbegriff des Patentanspruchs 1 näher bezeichneten Art.The invention relates to a device on a machine or a machine station for applying a strip or band-shaped edge material and for cutting this edge material, the type specified in the preamble of claim 1.
Stand der TechnikState of the art
Bekannte Vorrichtungen der vorgenannten Art werden zum Kappen des auf die Schmalseitenflächen der Werkstücke aufgebrachten Kantenmaterials eingesetzt. Eine Kantenanleimmaschine, mit der das Kantenmaterial an die Schmalseitenflä- chen der Werkstücke im Durchlauf angefahren werden kann, zeigt die Patentschrift DE 42 17 291 Cl. Das aufgebrachte Kantenmaterial wird üblicherweise nicht nur an seinen Längsseiten sondern auch in Durchlaufrichtung der Werkstücke gesehen sowohl am vorderen Ende der betreffenden Werk- stückschmalseitenfläche als auch an deren rückwärtigen Ende mit Überstand aufgebracht, und auch diese Überstände müssen in der Regel bündig mit den in Durchlaufrichtung vorn- und hintenliegenden Werkstückschmalseiten abgekappt werden. In bekannter Ausführung verwendet man hierfür Kappsägen, die nicht nur quer zur Durchlaufrichtung der Werkstücke zugestellt, sondern während des Kappvorgangs entlang eines Werkstücks in Durchlaufrichtung synchron mit den Werkstük- ken mitbewegt werden. Eine Durchlaufmaschine mit derartigen Kappaggregaten ist aus der Offenlegungsschrift EP 0 578 199 AI bekannt.Known devices of the aforementioned type are used for capping the edge material applied to the narrow side surfaces of the workpieces. The patent specification DE 42 17 291 Cl shows an edge banding machine with which the edge material can be approached to the narrow side surfaces of the workpieces in one pass. The applied edge material is usually applied not only on its long sides but also in the direction of passage of the workpieces, both at the front end of the narrow side of the workpiece in question and at the rear end thereof, and these protrusions as a rule also have to be flush with those at the front in the direction of passage - and the back of the narrow sides of the workpiece. In a known design, cross-cut saws are used for this purpose, which are not only fed transversely to the direction of the workpieces, but also synchronously with the workpieces during the cutting process along a workpiece in the direction of travel. not be moved. A continuous machine with such trimming units is known from the published patent application EP 0 578 199 AI.
An derartigen Durchlaufmaschinen oder entsprechenden Maschinenstationen ist aus den geschilderten Gründen ein Aufbauplatz für die Kappaggregate erforderlich, der eine er- hebliche Länge in Werkstückdurchlaufrichtung erfordert. Bei gängigen Maschinen muß dafür eine Länge von etwa 1.800 mm vorgesehen werden, was einen merklichen Teil der Gesamtlänge einer im Durchlauf arbeitenden Kantenanleimmaschine oder -Station ausmacht.In the case of through-feed machines or corresponding machine stations of this kind, a mounting location for the cross-cutting units is required for the reasons described, which requires a considerable length in the direction of the workpiece throughput. In conventional machines, a length of about 1,800 mm must be provided for this, which makes up a noticeable part of the total length of an edge banding machine or station working in a continuous operation.
Die ErfindungThe invention
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die an der Kanten- arileimmaschine oder -maschinenstation einen Aufbauplatz von geringer Länge in Werkstückdurchlaufrichtung benötigt und darüberhinaus für universelle Ein- oder Durchschnitte am Kantenmaterial einsetzbar ist.The invention has for its object to provide a device of the type mentioned that requires a build-up space of short length in the workpiece passage direction at the edge arile machine or machine station and can also be used for universal incisions or cuts on the edge material.
Diese Aufgabe wird bei einer Vorrichtung der gattungsbildenden Art nach der Erfindung durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved in a device of the generic type according to the invention by the characterizing features of claim 1.
Für die Erfindung ist wesentlich, daß das neue Rotations- messer ortsfest angeordnet ist und deshalb hierfür ein Ver- fahrweg in Werkstückdurchlaufrichtung nicht vorgesehen werden muß. Gegenüber den Kappaggregaten mit vergleichbarer Funktion reduziert sich die Länge des Aufbauplatzes für das ortsfeste Rotationsmesser auf das 0,15- bis 0,lfache. Das Schneiden des Kantenmaterials mit einer ein- oder durchtauchenden Messerschneide kann wesentlich schneller als das Durchtrennen des Kantenmateri-als mittels eines zerspanenden Sägeblattes vorgenommen werden. Darüber hinaus läßt sich das Mitführen der Schneide mit der jeweiligen Schnitt- stelle des auf die Werkstückschmalseitenflächen aufgebrachten Kantenmaterials durch entsprechende Drehung des Messerkörpers bewerkstelligen, wobei ferner noch an der Schnittstelle der Hub der Messerschneide quer zur Werkstückdurchlaufrichtung entsprechend der Projektion des Kreisbahnbo- gens, auf dem die Messerschneide beim Schneiden sich bewegt, auf die Radialrichtung senkrecht zur Werkstückdurchlaufrichtung für die Schnittiefe genutzt werden kann.It is essential for the invention that the new rotary knife is arranged in a fixed position and therefore a travel path in the direction of workpiece passage does not have to be provided for this. Compared to the cross-cut units with comparable Function, the length of the installation space for the stationary rotary knife is reduced to 0.15 to 0.1 times. The cutting of the edge material with a plunge or penetrating knife edge can be done much faster than cutting through the edge material than with a cutting saw blade. In addition, the cutting edge can be carried along with the respective interface of the edge material applied to the narrow side surfaces of the workpiece by appropriate rotation of the knife body, and furthermore at the interface the stroke of the cutting edge transversely to the direction of the workpiece passage in accordance with the projection of the circular arc on the the knife edge moves when cutting, can be used in the radial direction perpendicular to the workpiece pass direction for the depth of cut.

Das Kantenanleimaggregat weist eine Vorratsrolle 5 auf, von dem das Kantenmaterial 4 abgezogen und mittels Andruckrollen 6 unter Verkleben an die Schmalseitenflächen 3 der Werkstücke 1 herangeführt wird. Am Kantenanleimaggregat kann ein Kappmesser 7 vorgesehen sein, um einen Streifen vorbestimmter Länge von dem Kantenmaterial 4 abzuschneiden, der für die Beschichtung einer Schmalseitenfläche 3 der Werkstücke 1 vorgesehen ist.1 shows workpieces 1 which are conveyed on a transport chain 2 in the direction of arrow A. Here, the one narrow side surfaces 3 of the workpieces 1 are arranged in alignment in the conveying direction, so that an edge strip 4 can be applied to it while passing an edge banding unit. The edge banding unit has a supply roll 5, from which the edge material 4 is drawn off and brought to the narrow side surfaces 3 of the workpieces 1 by means of pressure rollers 6 while adhering. A cutting knife 7 can be provided on the edge banding unit in order to cut a strip of predetermined length from the edge material 4, which is provided for coating a narrow side surface 3 of the workpieces 1.
Nach dem Vorbeilaufen an dem Kantenanleimaggregat passieren die Werkstücke 1 Bündigfräsaggregate 8, welche das Kanten- material 4 auf der beschichteten Schmalseitenfläche 3 der Werkstücke 1 ober- und unterseitig bündig mit der Ober- und Unterseite der plattenför igen Werkstücke 1 besäumen. An- schließend werden die Werkstücke 1 auf der Transportkette 2 im weiteren Durchlauf an einem Rotationsmesser 9 vorbeige- führt, welches am Durchlauf eg ortsfest angeordnet ist und das nachstehend noch näher beschrieben werden wird.After running past the edge banding unit, the workpieces 1 pass flush trimming units 8 which trim the edge material 4 on the coated narrow side surface 3 of the workpieces 1 flush with the top and bottom of the plate-shaped workpieces 1. On- finally, the workpieces 1 on the transport chain 2 are passed in the further pass past a rotary knife 9, which is arranged stationary on the pass eg and which will be described in more detail below.
Mit dem Rotationsmesser 9 werden die in Durchlaufrichtung vorderen und hinteren Überstände des auf die Schmalseiten- flächen 3 der Werkstücke 1 aufgetragenen Kantenmaterials 4 gekappt. Dazu zeigt Fig. 2 jeweils den Betrag C und D, um den das Kantenmaterial 4 über die in Förderrichtung der Werkstücke 1 vorn liegenden Werkstückschmalseiten 26 und hinten liegenden Werkstückschmalseiten 27 übersteht.

Das Kappmesser 9 hat einen scheibenförmigen Messerkörper 10, dessen Umriß oder Umhüllende kreisförmig bzw. zylinder- förmig ist. Mit der Kreis- bzw. Zylinderachse des Messerkörpers 10 fällt eine Antriebsachse oder -welle 12 zusammen, über die das gesamte Rotationsmesser 9 drehend antreibbar ist. An zwei einander diametral gegenüberliegenden Stellen weist der Messerkörper 10 sektorartige Aussparungen 23 auf, deren jeweils eine Flanke 25 radial bzw. radiusparallel zur Antriebsachse 12 liegt. Diese Flanke 25 dient zur Anlage von Messerklingen 11, die mit einem freien Ende radial nach außen über den Messerkörper 10 vorstehen, wobei sich an diesem Ende eine Messerschneide 13 befindet.The cutting knife 9 has a disk-shaped knife body 10, the outline or envelope of which is circular or cylindrical. A drive axis or shaft 12 coincides with the circular or cylindrical axis of the knife body 10, via which the entire rotary knife 9 can be driven in rotation. At two diametrically opposite points, the knife body 10 has sector-like recesses 23, each of which has a flank 25 lying radially or radius-parallel to the drive axis 12. This flank 25 serves for the abutment of knife blades 11, which project radially outward beyond the knife body 10 with a free end, a knife edge 13 being located at this end.
Der Messerkörper 10 wird in Richtung des Pfeiles B angetrieben. Während des Schneidvorgangs wälzt sich der Messer- körper 10 quasi an der an ihm vorbeilaufenden, mit dem Kantenmaterial 4 beschichteten Schmalseitenfläche 3 der Werk- stücke 1 ab und wird hierbei so gesteuert, daß die betreffende Messerschneide 13 an der vorgesehenen Schnittstelle in Eingriff mit dem Kantenmaterial 4 kommt. Dabei wird die Messerschneide 13 durch Drehung des Messerkörpers 10 mit dem Durchlauf des zu schneidenden Kantenstreifens 4 mitge- führt und taucht in das Material des Kantenstreifens 4 ein bzw. durch dieses Material hindurch, um danach aus der Eingriffslage mit der Schnittstelle herausgedreht zu werden. Es versteht sich, daß die Länge der Messerschneiden 13 in Höhenrichtung gesehen gleich groß oder größer als die Brei- te des Kantenmaterials 4 sein muß. Außerdem ist der radiale Überstand der Messerschneiden 13 über den Messerkörper 10 hinaus ausreichend groß, um eine Kollision zwischen den Werkstücken 1 bzw. dem darauf aufgebrachten Kantenmaterial 4 und dem Messerkörper 10 auszuschließen. So kann der Mes- serkörper 10, an dem die beschichteten Werkstückschmalseiten tangential oder tangentenparallel vorbeilaufen einen geringen Abstand von diesen Werkstückschmalseiten haben.The knife body 10 is driven in the direction of arrow B. During the cutting process, the knife Body 10 quasi from the narrow side surface 3 of the workpieces 1 running past it and coated with the edge material 4 and is controlled in such a way that the relevant knife edge 13 comes into engagement with the edge material 4 at the intended interface. The knife edge 13 is carried along with the passage of the edge strip 4 to be cut by rotating the knife body 10 and is immersed in the material of the edge strip 4 or through this material in order to then be turned out of the engagement position with the interface. It goes without saying that the length of the knife edges 13, viewed in the vertical direction, must be the same size or greater than the width of the edge material 4. In addition, the radial projection of the knife edges 13 beyond the knife body 10 is sufficiently large to rule out a collision between the workpieces 1 or the edge material 4 applied thereon and the knife body 10. Thus, the knife body 10, along which the coated narrow sides of the workpiece run tangentially or tangentially parallel, can have a small distance from these narrow sides of the workpiece.
Wie aus Fig. 4 hervorgeht, muß für den Schnitt des Kanten- materials 4 bündig mit der in Durchlaufrichtung vornliegenden Werkstückschmalseite 26 eine andere Anordnung der Messerschneide 13 am Rotationsmesser 9 vorgesehen werden als für den Schnitt bündig mit der in Durchlaufrichtung der Werkstücke 1 rückwärts liegenden Werkstückschmalseite 27. Auch das veranschaulicht Fig. 3, ergänzend zu der Darstellung von Fig. 4. Die Schneiden 13 an den beiden Klingen 11 sind über die Klingendicke hinweg schräg geschliffen. Dabei befindet sich jeweils die Schneide 13 in der Ebene einer ebenen Flanke oder Außenseite 24 jeder Klinge 11. Die eine Klinge 11 ist mit dieser ebenen Flanke 24 an die Flanke 25 der Aussparung 23 des Messerkörpers 10 angelegt, die zweite Klinge 11 entsprechend mit ihrer der ebenen Flanke 24 gegenüberliegenden Seite. Die Rotation des Messerkörpers 10 wird nun so gesteuert, daß die ebenen Seiten 24 der Klingen 11, welche in die Schneiden 13 auslaufen, zum einen zu der auflaufenden, in Durchlaufrichtung der Werkstücke 1 vornliegenden Werkstückschmalseite 26 und zum anderen zu der in Durchlaufrichtung der Werkstücke 1 rückwärtigen, ablaufenden Werkstückschmalseite 27 hin angeordnet sind. Dadurch ergeben sich optimale Schnittbedingungen an den beiden zu kappenden Enden des jeweiligen Kantenstreifens 4, außerdem steht durch die Aussparungen 23 am Messerkörper 10 ein genügender Spanraum zur Verfügung.As can be seen in FIG. 4, a different arrangement of the knife edge 13 on the rotary knife 9 must be provided for the cutting of the edge material 4 flush with the narrow side 26 of the workpiece in the direction of flow than for the cut flush with the narrow side of the workpiece 1 lying back in the direction of flow of the workpieces 1 27. This is also illustrated in FIG. 3, in addition to the illustration in FIG. 4. The cutting edges 13 on the two blades 11 are ground obliquely across the blade thickness. there is the cutting edge 13 in the plane of a flat flank or outside 24 of each blade 11. One blade 11 is placed with this flat flank 24 on the flank 25 of the recess 23 of the knife body 10, the second blade 11 correspondingly with its flat one Flank 24 opposite side. The rotation of the knife body 10 is now controlled in such a way that the flat sides 24 of the blades 11, which run out into the cutting edges 13, on the one hand to the upstream narrow workpiece side 26, which is in the direction of flow of the workpieces 1, and on the other hand, in the direction of the workpieces 1 rear, running workpiece narrow side 27 are arranged. This results in optimal cutting conditions at the two ends of the respective edge strip 4 to be cut, and there is also a sufficient chip space available through the cutouts 23 on the knife body 10.
Fig. 5 macht ebenso wie Fig. 4 deutlich, daß grundsätzlich in Durchlaufrichtung der Werkstücke 1 gesehen hintereinander auch zwei oder mehrere Rotationsmesser 9 angeordnet sein können. Weiter geht aus Fig. 5 hervor, daß Trenn- oder Einschnitte mittels des Rotationsmessers 9 auch im Verlauf der Schmalflächenseite 3, auf die das Kantenmaterial 4 aufgebracht ist, ausgeführt werden können. Dies ist beispielsweise der Fall, wenn es sich bei dem Kantenmaterial 4 um ein solches handelt, welches mit einem Dichtwulst 4a versehen ist, wie Fig. 5a deutlich macht. Hierbei kann es erfor- derlich sein, den Dichtwulst 4a nur über eine Länge G sich erstrecken zu lassen und zu oder zwischen den weiteren Abschnitten des Dichtwulstes 4a Lücken F und H zu lassen. Fig. 6 zeigt eine andere Verwendungsmöglichkeit des Rotationsmessers 6, die dann vorgesehen wird, wenn eine Mehrzahl von Werkstücken 1 in einer dichten Folge mittels des Kantenanleimaggregates der Kantenanleimmaschine an den miteinander fluchtenden Werkstückschmalseitenflächen gemeinsam mit einem Streifen des Kantenmaterials 4 beschichtet worden sind. Die dann zunächst noch zusammenhängenden Werkstücke 1 können an den zwischen diesen bestehenden Lücken J voneinander getrennt werden, indem mittels des Rotationsmessers 9 der Streifen des Kantenmaterials 4 durchtrennt wird.FIG. 5, like FIG. 4, makes it clear that two or more rotary knives 9 can also be arranged one behind the other, as seen in the direction of travel of the workpieces 1. 5 that cut or cuts can be made by means of the rotary knife 9 also in the course of the narrow surface side 3 to which the edge material 4 is applied. This is the case, for example, if the edging material 4 is one that is provided with a sealing bead 4a, as shown in FIG. 5a. It may be necessary here to allow the sealing bead 4a to extend only over a length G and to leave gaps F and H to or between the further sections of the sealing bead 4a. 6 shows another possible use of the rotary knife 6, which is provided when a plurality of workpieces 1 have been coated in a dense sequence by means of the edge banding unit of the edge banding machine on the aligned narrow side surfaces of the workpiece together with a strip of edge material 4. The workpieces 1, which are then still contiguous, can be separated from one another at the gaps J existing between them by severing the strip of the edge material 4 by means of the rotary knife 9.
Die Figuren 7 und 8 zeigen eine besondere Anordnung für das Rotationsmesser 9. Diese Bauform wird insbesondere dann vorgesehen, wenn das auf die Werkstücke 1 aufgetragene Kantenmaterial 4 nicht durchtrennt sondern lediglich angeschnitten oder davon etwas abgeschnitten werden soll. Hierbei geht es darum, das Rotationsmesser 9 federnd gegen das Kantenmaterial 4 an den betreffenden Schmalseitenflächen der Werkstücke 1 anzudrücken.FIGS. 7 and 8 show a special arrangement for the rotary knife 9. This design is provided in particular when the edge material 4 applied to the workpieces 1 is not to be cut but only to be cut or somewhat cut off from it. This involves pressing the rotary knife 9 resiliently against the edge material 4 on the narrow side surfaces of the workpieces 1 in question.
Zunächst veranschaulichen die Figuren 7 und 8 grundsätzliche Merkmale für den Antrieb des Rotationsmessers 9. Dazu ist das Rotationsmesser 9 über eine Welle 12, welche die Rotationsachse darstellt, mit einem Positionierantrieb 15 verbunden, der so angesteuert wird, daß die betreffende Messerschneide der vorgesehenen Schnittstelle am Bandmaterial 4 nachfolgt. Weiteres Element des Steuerungssystems für das Rotationsmesser 9 ist ein Sensor 14, der Referenzstellen oder -marken an den durchlaufenden Werkstücken 1 abtastet. Es kann sich hierbei um die quer zur Förderrich- tung der Werkstücke 1 liegenden Werkstückschmalseiten 26 oder 27 (Fig. 2) handeln. Spricht der Sensor 14 an, wird über eine Wegstrecke K ein Steuerbefehl an den Positionierantrieb 15 gegeben, der daraufhin das Rotationsmesser 9 so dreht, daß die betreffende Messerschneide in passenden Eingriff mit dem Kantenmaterial 4 bzw. mit dem daran angebrachten Dichtwulst 4a kommt. Sind zwei Messerschneiden 13 an dem Rotationsmesser 9 vorhanden, wie es Fig. 3 veranschaulicht, dann führt das Rotationsmesser 9 für einen Schneidvorgang an einer der beiden Plattenschmalseiten 26, 27 eine Drehung von 180° aus.First of all, FIGS. 7 and 8 illustrate basic features for the drive of the rotary knife 9. For this purpose, the rotary knife 9 is connected via a shaft 12, which represents the axis of rotation, to a positioning drive 15, which is controlled in such a way that the relevant knife edge of the intended interface on Tape material 4 follows. Another element of the control system for the rotary knife 9 is a sensor 14 which scans reference points or marks on the workpieces 1 passing through. This can be the cross-feed direction device of the workpiece 1 lying workpiece narrow sides 26 or 27 (Fig. 2) act. If the sensor 14 responds, a control command is given to the positioning drive 15 over a distance K, which then rotates the rotary knife 9 so that the knife edge in question comes into suitable engagement with the edge material 4 or with the sealing bead 4a attached to it. If two knife edges 13 are present on the rotary knife 9, as illustrated in FIG. 3, the rotary knife 9 rotates 180 ° for one cutting operation on one of the two narrow sides 26, 27 of the plate.
Weiter gehen aus den Figuren 7 und 8 diejenigen Merkmale hervor, die eine federnde Beaufschlagung des Rotationsmessers 9 hin zu den durchlaufenden Werkstücken 1 bewirken. Dazu ist das Rotationsmesser mit seinem Positionierantrieb 15 an einem Schlitten 18 angeordnet, der auf Führungsstan- gen 17 quer zur Durchlaufrichtung der Werkstücke 1 verfahrbar ist. Die Führungsstangen 17 sind mittels einer Halte- rung 16 an dem in den Figuren 7 und 8 andeutungsweise dargestellten Maschinengestell 29 befestigt. Der Schlitten 18 wird von einem Pneumatikzylinder 19 beaufschlagt, und die Abstützung des Schlittens 18 einschließlich dem Rotationsmesser 9 an der durchlaufenden Schmalseitenfläche der jeweiligen Werkstücke 1 bzw. an dem darauf angebrachten Kantenmaterial 4 erfolgt über ein Tastrad 20, welches an einem auf dem Schlitten 18 angeordneten Tragarm 28 gelagert ist. Zur Einstellung der Schnittiefe der Messerschneiden am Rotationsmesser 9 dient eine Stellschraube 21 mit entsprechender Stellspindel, über die die Achse des Tastrades 20 relativ zu der Achse des Rotationsmessers 9 quer zur Durchlaufrichtung der Werkstücke 1 verstellt werden kann.FIGS. 7 and 8 also show those features which cause the rotary knife 9 to act resiliently towards the workpieces 1 passing through. For this purpose, the rotary knife with its positioning drive 15 is arranged on a carriage 18, which can be moved on guide rods 17 transversely to the direction of travel of the workpieces 1. The guide rods 17 are fastened by means of a holder 16 to the machine frame 29, which is indicated in FIGS. 7 and 8. The carriage 18 is acted upon by a pneumatic cylinder 19, and the carriage 18 including the rotary knife 9 is supported on the continuous narrow side surface of the respective workpieces 1 or on the edge material 4 attached thereon by means of a feeler wheel 20 which is arranged on a carriage 18 Support arm 28 is mounted. An adjusting screw 21 with a corresponding adjusting spindle, via which the axis of the feeler wheel 20 is used, is used to adjust the depth of cut of the knife edges on the rotary knife 9 can be adjusted relative to the axis of the rotary knife 9 transversely to the direction of travel of the workpieces 1.
Im übrigen ist in Fig. 8 noch ein Oberdruck 30 dargestellt, welcher mit den Werkstücken 1 mitläuft und diese gegen die Transportkette 2 preßt.In addition, an upper pressure 30 is shown in FIG. 8, which moves with the workpieces 1 and presses them against the transport chain 2.
Fig. 9 zeigt eine Anordnung von zwei Rotationsmessern 9, wie sie vorzugsweise dann vorgesehen wird, wenn die Werkstücke 1 in der Durchlaufrichtung A eine dichte Folge mit einem engen Abstand J aufweisen. In gleicher Art wie nach dem Ausführungsbeispiel der Figuren 7 und 8 sind die beiden Rotationsmesser 9 je auf einem Schlitten 18 angeordnet, der jedoch zwei Haltearme 31 aufweist, die in Richtung zu den durchlaufenden Werkstücken 1 vorstehen und je ein Tastrad 22 bzw. eine Tastrolle tragen. Diese Haltearme 31 umgreifen das jeweilige Rotationsmesser seitlich, so daß in Durchlaufrichtung der Werkstücke 1 gesehen die Rotationsmesser 9 und die Tasträder 22 einen Achsabstand haben. Bei dieser Ausführung ragen die Rotationsmesser 9 sozusagen durch die Tastung hindurch. FIG. 9 shows an arrangement of two rotary knives 9, as is preferably provided when the workpieces 1 have a tight sequence with a narrow distance J in the direction of passage A. In the same way as in the exemplary embodiment in FIGS. 7 and 8, the two rotary knives 9 are each arranged on a carriage 18, which, however, has two holding arms 31 which protrude in the direction of the workpieces 1 passing through and each carry a feeler wheel 22 or a feeler roller , These holding arms 31 encompass the respective rotary knife laterally, so that the rotary knives 9 and the feeler wheels 22 have a center distance when viewed in the direction of travel of the workpieces 1. In this embodiment, the rotary knives 9 protrude through the feel, so to speak.
