Description

Die Erfindung betrifft ein Verfahren zum Herstellen eines Profils eines Profilmessers mittels mindestens eines Schleifwerkzeuges nach dem Oberbegriff des Anspruches 1.The invention relates to a method for producing a profile of a profile knife by means of at least one grinding tool according to the preamble of claim 1.

Zur Herstellung von unterschiedlichen Profilen an Hölzern für beispielsweise Fensterrahmen müssen die Profilmesser mit dem jeweils erforderlichen Profil versehen werden. Hierzu wird eine Schablone angefertigt, die das notwendige Profil hat. Beim bekannten Verfahren (GB-A-2 082 501) wird die Schablone in einem Schablonenträger eingespannt, während ein Rohling zur Herstellung des Profilmessers in einem Halter eingeklemmt wird. Mit dem Schleifwerkzeug wird dann durch Abtasten des Profiles der Schablone mit dem Kopierteil das entsprechende Profil in den Messerrohling geschliffen. Auf diese Weise werden die Profilmesser einzeln nacheinander hergestellt. Damit die Profilmesser lagegenau im Messerkopf der Bearbeitungsmaschine befestigt werden können, sind an den Profilmessern Ausrichtflächen erforderlich, die mit nockenartigen Ansätzen eines Klemmkeiles einer Spannvorrichtung der Bearbeitungsmaschine zusammenwirken. Die Profilmesser haben darum eine komplizierte Formgebung. Außerdem ist der Einbau der Profilmesser in den Messerkopf aufwendig. Darum gestaltet sich auch der Werkzeugwechsel zeitaufwendig, und die Umrüst- und Stillstandszeiten der Bearbeitungsmaschine sind verhältnismäßig hoch. Trotz der Ausrichtflächen muß die genaue Lage der Profilmesser in der Bearbeitungsmaschine überprüft werden, wozu ein Probelauf durchgeführt wird. Hierfür ist jedesmal ein Werkstück notwendig, das stets dann Ausschuß ist, wenn die Messereinstellung nicht genau stimmt.To produce different profiles on wood for window frames, for example, the profile knives must be provided with the required profile. For this purpose, a template is made that has the necessary profile. In the known method (GB-A-2 082 501) the template is clamped in a template holder, while a blank for producing the profile knife is clamped in a holder. With the grinding tool, the corresponding profile is then ground into the knife blank by scanning the profile of the template with the copying part. In this way, the profile knives are manufactured one after the other. In order that the profile knives can be fixed in position in the cutter head of the processing machine, alignment surfaces are required on the profile knives that interact with cam-like approaches of a clamping wedge of a clamping device of the processing machine. The profile knives therefore have a complicated shape. In addition, the installation of the profile knives in the cutter head is complex. That is why the tool change is time-consuming, and the changeover and downtimes of the processing machine are relatively high. Despite the alignment surfaces, the exact position of the profile knives in the processing machine must be checked, for which a test run is carried out. This requires a workpiece every time, which is always rejected if the knife setting is not exactly correct.

Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Verfahren so auszubilden, daß die Profilmesser so hergestellt werden können, daß ein einfacher Werkzeugwechsel möglich ist, die Ausschußquote bei Überprüfen der Lage der Profilmesser minimiert und die Umrüst- und Stillstandszeiten der Bearbeitungsmaschine auf ein Minimum herabgesetzt werden.The invention has for its object to design the generic method so that the profile knives can be manufactured so that a simple tool change is possible, the reject rate is minimized when checking the position of the profile knives and the changeover and downtimes of the processing machine are reduced to a minimum .

Beim erfindungsgemäßen Verfahren werden die zu schleifenden Profilmesser in den Messerkopf eingespannt, so daß jederzeit eine genaue Zuordnung der Profilmesser und ihrer Profile zum Messerkopf gewährleistet ist. Das Profilmesser wird beim erfindungsgemäßen Verfahren derart in den Messerkopf eingespannt, daß der Profilanfang des Profilmessers vom Messerkopf-Anschlag einen vorgegebenen Abstand hat, der dem Abstand entspricht, den der Profilanfang des Werkstückes von der Anlage der Maschinenspindel hat, auf welche der Messerkopf in der Bearbeitungsmaschine, vorzugsweise einer Kehlmaschine, gespannt wird. Die genaue Lage des Messerkopfes zum Schleifvorgang läßt sich sehr einfach dadurch einstellen, daß der Messerkopf zur Anlage am Anschlag des Halters gebracht wird. Aufgrund der erfindungsgemäßen Ausbildung kann der Messerkopf mit dem geschliffenen Profilmesser sofort anschließend auf die Spindel der Bearbeitungsmaschine geschoben und gespannt werden. Das Profilmesser nimmt dann seine exakte Lage innerhalb der Bearbeitungsmaschine ein, so daß ohne Durchführung eines Probelaufes der Messerkopf mit den geschliffenen Profilmessern in Betrieb genommen werden kann. Ein entsprechender Werkstückausschuß tritt darum nicht auf. Insbesondere sind die Umrüst- und Stillstandszeiten der Bearbeitungsmaschine für den Werkzeugwechsel infolge des erfindungsgemäßen Verfahrens äußerst gering.In the method according to the invention, the profile knives to be ground are clamped in the cutter head, so that an exact assignment of the profile knives and their profiles to the cutter head is guaranteed at all times. The profile knife is clamped in the cutter head in the method according to the invention in such a way that the profile start of the profile knife has a predetermined distance from the cutter head stop, which corresponds to the distance that the profile start of the workpiece has from the system of the machine spindle to which the cutter head in the processing machine , preferably a moulder. The exact position of the cutter head for the grinding process can be set very easily by bringing the cutter head into contact with the stop of the holder. Due to the design according to the invention, the knife head with the ground profile knife can then be pushed and clamped immediately on the spindle of the processing machine. The profile knife then takes up its exact position within the processing machine, so that the cutter head with the ground profile knives can be put into operation without carrying out a test run. A corresponding workpiece scrap therefore does not occur. In particular, the changeover and downtimes of the processing machine for the tool change are extremely short as a result of the method according to the invention.

Mit der nachfolgend beschriebenen Einrichtung kann ein Werkzeugwechsel bei einer Kehlmaschine einfach und schnell durchgeführt werden. Erreicht wird dies dadurch, daß eine Schablone, nach der ein Profilmesser hergestellt wird, eine Schleifmaschine zur Herstellung dieses Profilmessers und die Kehlmaschine aufeinander abgestimmt sind. Die Ausschußquote bei Einstellarbeiten wird infolge dieser Einrichtung nahezu auf 0 reduziert. Die Umrüst- und Stillstandszeiten der Kehlmaschine werden auf ein Minimum herabgesetzt.With the device described below, a tool change in a moulder can be carried out quickly and easily. This is achieved in that a template according to which a profile knife is produced, a grinding machine for producing this profile knife and the moulder are matched to one another. The reject rate for adjustment work is reduced to almost 0 as a result of this facility. The changeover and downtimes of the moulder are reduced to a minimum.

Zur Herstellung der Profilmesser wird zunächst eine Profilschablone 1 hergestellt (Fig. 1). Hierzu wird ein Schablonenblech im Maßstab 1:1 von einem Holzmuster oder einer Zeichnung unverzerrt und in Gegenprofilfrom hergestellt. Dieses Gegenprofil der Profilschablone 1 ist in Fig. 1 mit 6 bezeichnet. Das zu profilierende Holz ist in Fig. 1 mit 2 bezeichnet. Die Profilschablone 1 hat eine Anlageseite 3 und eine quer, vorzugsweise senkrecht dazu liegende Anschlagseite 4. Auf der der Anlageseite 3 gegenüberliegenden Seite 5 der Profilschablone 1 befindet sich das jeweilige Profil 6. Die größte Profilausnehmung befindet sich in einem Abstand 7 von der Anlageseite 3. Außerdem wird das Profil 6 derart an der Seite 5 angebracht, daß das Profil 6 mit einem genauen Abstand 8 von der Anschlagseite 4 aus beginnt. Dieser Abstand 8 beträgt im Ausführungsbeispiel 20mm.To produce the profile knives, a profile template 1 is first produced (FIG. 1). For this purpose, a stencil sheet on a scale of 1: 1 is undistorted from a wooden sample or drawing and manufactured in counter-profile form. This counter profile of the profile template 1 is designated 6 in FIG. 1. The wood to be profiled is designated by 2 in FIG. 1. The profile template 1 has a contact side 3 and a transverse, preferably perpendicular stop side 4. The respective profile 6 is located on the side 5 of the profile template 1 opposite the contact side 3. The largest profile recess is located at a distance 7 from the contact side 3. In addition, the profile 6 is attached to the side 5 such that the profile 6 begins at a precise distance 8 from the stop side 4. In the exemplary embodiment, this distance 8 is 20 mm.

Nach dieser Profilschablone 1 wird das Profilmesser 9 (Fig. 3) hergestellt. Die Profilschablone 1 wird hierzu in einem Schablonenträger 10 befestigt (Fig. 2). Er hat eine Anschlagfläche 11, an der die Profilschablone 1 mit ihrer Anlageseite 3 anliegt. Der Schablonenträger 10 weist zwei Anschlagzapfen 12 auf, auf die eine Null-Scheibe 13 gesteckt werden kann.After this profile template 1, the profile knife 9 (Fig. 3) is produced. For this purpose, the profile template 1 is fastened in a template carrier 10 (FIG. 2). It has a stop surface 11 on which the profile template 1 rests with its contact side 3. The template carrier 10 has two stop pins 12 on which a zero disc 13 can be inserted.

Im Bereich neben dem Schablonenträger 10 ist ein Schleifdorn 14 gelagert, auf dem in bekannter Weise ein Werkzeug 31, 31a gespannt ist. Mit Hilfe eines Stellrades 15 wird von Hand während des Schleifens eines im Werkzeug 31, 31a eingespannten Profilmessers 9, 9ʹ das Messer mit seiner Brustseite auf einem nicht dargestellten Festanschlag aufgelegt. Der Schleifdorn 14 hat zwei Bünde 16 und 17, deren einander zugewandte Seiten 18 und 19 einen Abstand 20 voneinander haben. Er beträgt im Ausführungsbeispiel 225 mm.In the area next to the template carrier 10, a grinding mandrel 14 is mounted, on which a tool 31, 31a is clamped in a known manner. With the help of an adjusting wheel 15, the knife is placed with its chest side on a fixed stop (not shown) by hand while grinding a profile knife 9, 9ʹ clamped in the tool 31, 31a. The grinding arbor 14 has two collars 16 and 17, the mutually facing sides 18 and 19 of which are spaced 20 apart. In the exemplary embodiment, it is 225 mm.

Der Schablonenträger 10 und der Schleifdorn 14 sind gemeinsam auf einem Kreuzschlitten 28 horizontal in zwei Richtungen verfahrbar.The template carrier 10 and the grinding arbor 14 can be moved horizontally in two directions together on a cross slide 28.

Dem Schleifdorn 14 gegenüber befindet sich eine Schleifscheibe 21, die drehfest auf einer Spindel 22 eines Antriebsmotors 23 sitzt, der mit dem Maschinenständer verbunden ist. Die Schleifscheibe 21 ist drehbar vom Antriebsmotor 23 angetrieben. Mit der Schleifscheibe 21 wird das Profil in dem Profilmesser 9 geschliffen.Opposite the grinding arbor 14 is a grinding wheel 21, which is non-rotatably seated on a spindle 22 of a drive motor 23 which is connected to the machine stand. The grinding wheel 21 is rotatably driven by the drive motor 23. The profile is ground in the profile knife 9 with the grinding wheel 21.

Zum Abtasten des Profiles 6 der Profilschablone 1 dient ein Kopierstift 24, der auf einem Träger 25 mit dem Maschinenständer verbunden ist. Über den Kreuzschlitten 28 wird das Profil 6 längs am Kopierstift 24 entlangtastend verschoben, wobei in bekannter Weise die Schleifscheibe 21 relativ zum Profilmesser 9 ein dem Profil 6 entsprechendes Profil 26 in das Profilmesser 9 schleift.A copying pen 24, which is connected to the machine stand on a support 25, is used to scan the profile 6 of the profile template 1. Via the cross slide 28, the profile 6 is shifted longitudinally along the copying pin 24, the grinding wheel 21 in a known manner relative to the profile knife 9, a profile 26 corresponding to the profile 6 into the profile knife 9 grinds.

Vor Beginn des Schleifvorganges wird die Schleifscheibe 21 auf eine Dicke abgezogen, die dem Durchmesser des Kopierstiftes 24 entspricht. Anschließend wird der Schleifdorn 14 in die Lager gelegt und im Ausführungsbeispiel gemäß Fig. 2 nach rechts gegen eine Anschlaglasche 27 geschoben. An ihr liegt dann der Bund 17 an. In dieser Lage wird der Schleifdorn 14 festgeklemmt. Anschließend wird auf den in Fig. 2 rechten Anschlagzapfen 12 die Null-Scheibe 13 gesteckt und die Profilschablone 1 so weit längs der Anschlagfläche 11 des Schablonenträgers 10 verschoben, bis sie mit ihrer Anschlagseite 4 an der Null-Scheibe 13 anliegt (Fig 2). In dieser Lage wird die Profilschablone 1 festgeklemmt. Der Kopierstift 24 wird an die Anschlagseite 4 angelegt. Anschließend wird der Schablonenträger 10, der zusammen mit dem Schleifdorn 14 auf einem gemeinsamen Kreuz-Tisch 28 angeordnet ist, so lange verschoben, bis ein an die Innenseite 19 des Bundes 17 des Schleifdornes 14 angelegtes Einstellteil 29 die Schleifscheibe 21 berührt. Diese Stellung ist in Fig. 2 mit ausgezogenen Linien dargestellt. Dadurch ist die Schleifscheibe 21 in bezug auf das zu schleifende Profilmesser 9 genau ausgerichtet.Before the grinding process begins, the grinding wheel 21 is pulled off to a thickness which corresponds to the diameter of the copying pin 24. The grinding arbor 14 is then placed in the bearing and, in the exemplary embodiment according to FIG. 2, pushed to the right against a stop tab 27. The collar 17 is then attached to it. In this position, the grinding arbor 14 is clamped. Subsequently, the zero washer 13 is plugged onto the stop pin 12 on the right in FIG. 2 and the profile template 1 is displaced along the stop face 11 of the template carrier 10 until its stop side 4 abuts the zero washer 13 (FIG. 2). In this position, the profile template 1 is clamped. The copy pen 24 is placed on the stop side 4. Then the template holder 10, which is arranged together with the grinding arbor 14 on a common cross table 28, is moved until an adjusting part 29 placed on the inside 19 of the collar 17 of the grinding arbor 14 touches the grinding wheel 21. This position is shown in Fig. 2 with solid lines. As a result, the grinding wheel 21 is precisely aligned with respect to the profile knife 9 to be ground.

Zur zusätzlichen Kontrolle wird auf den in Fig. 2 linken Anschlagzapfen 12 ebenfalls eine Null-Scheibe 13 gesteckt (strichpunktierte Linie), und die Profilschablone 1 mit ihrer der Anschlagseite 4 gegenüberliegenden Seite an die Null-Scheibe angelegt.For additional control, a zero washer 13 is also inserted on the stop pin 12 on the left in FIG. 2 (dash-dotted line), and the profile template 1 with its side opposite the stop side 4 is placed against the zero washer.

Der Kopierstift 24 befindet sich dann ebenfalls in der Ausgangsstellung auf der gegenüberliegenden Schablonenseite (strichpunktierte Linie in Fig. 2).Der Einstellteil 29 wird nunmehr an der Seite 18 des Bundes 16 des Schleifdornes 14 angelegt und der Tisch 28 so lange verschoben, bis der Einstellteil 29 die Schleifscheibe 21 an der gegenüberliegenden Seite berührt. Der Abstand 20 zwischen den beiden einander zugewandten Seiten 18 und 19 der Bunde 16, 17 ist gleich dem Abstand 30 zwischen den beiden auf den Anschlagzapfen 12 befindlichen Null-Scheibe 13. Auf die beschriebene Weise läßt sich die Schleifmaschine exakt einstellen.The copying pen 24 is then also in the starting position on the opposite side of the template (dash-dotted line in FIG. 2). The setting part 29 is now placed on the side 18 of the collar 16 of the grinding arbor 14 and the table 28 is moved until the setting part 29 touches the grinding wheel 21 on the opposite side. The distance 20 between the two mutually facing sides 18 and 19 of the collars 16, 17 is equal to the distance 30 between the two zero disc 13 located on the stop pin 12. The grinding machine can be set exactly in the manner described.

Nach dem beschriebenen Einstellvorgang wird das Profilmesser 9 hergestellt. Es wird in einem Messerkopf 31 (Fig. 3) befestigt, der während des Schleifens des Profilmesses 9 auf dem Schleifdorn 14 gelagert und gehalten wird. Der Messerkopf 31 wird im Ausführungsbeispiel hydraulisch auf dem Schleifdorn 14 festgeklemmt. Der Messerkopf 31 hat einen über seine Stirnseite geringfügig ragenden Lagerteil 32, der in der Betriebslage (Fig. 3) mit seiner Anlagefläche 32ʹ an der Seite 19 des Bundes 17 anliegt. Das zu schleifende Profilmesser 9 ist so im Messerkopf 31 eingespannt, daß seine eine Seitenfläche 33 bündig mit der entsprechenden Stirnseite 34 des Messerkopfes liegt. Da zuvor die Schleifscheibe 21 mit dem Einstellteil 29 so gegenüber dem Schleifdorn 14 ausgerichtet ist, daß die Seite 19 des Bundes 17 in einer gemeinsamen Ebene mit der einen Seite der Schleifscheibe 21 liegt (Fig. 2 und 3), ist die Schleifscheibe 21 genau gegenüber dem Profilmesser 9 ausgerichtet, das heißt ihre entsprechende Seite liegt in einer Ebene mit der Seite 19 des Bundes 17. Da in der Ausgangsstellung auch der Kopierstift 24 an der Anschlagseite 4 der Profilschablone 1 anliegt, ist das Profilmesser gegenüber der Schleifscheibe genau gleich ausgerichtet wie die Profilschablone 1 in bezug auf den Kopierstift 24.After the adjustment process described, the profile knife 9 is produced. It is fastened in a cutter head 31 (FIG. 3), which is mounted and held on the grinding arbor 14 during the grinding of the profile knife 9. In the exemplary embodiment, the cutter head 31 is clamped hydraulically on the grinding arbor 14. The cutter head 31 has a bearing part 32 which projects slightly over its end face and which, in the operating position (FIG. 3), bears with its contact surface 32 'on the side 19 of the collar 17. The profile knife 9 to be ground is clamped in the cutter head 31 such that its one side surface 33 lies flush with the corresponding end face 34 of the cutter head. Since the grinding wheel 21 is previously aligned with the adjusting part 29 in relation to the grinding arbor 14 in such a way that the side 19 of the collar 17 lies in a common plane with one side of the grinding wheel 21 (FIGS. 2 and 3), the grinding wheel 21 is exactly opposite the profile knife 9 aligned, that is, their corresponding side lies in one plane with the side 19 of the federal government 17. Since in the starting position the copier pin 24 also bears against the stop side 4 of the profile template 1, the profile knife is aligned with the grinding wheel in exactly the same way as that Profile template 1 with respect to the copy pin 24th

Nunmehr wird mit der Schleifscheibe 21 in bekannter Weise das Profil 26 im Profilmesser 9 hergestellt, indem der Schablonenträger 10 mit dem Schleifdorn 14 so über den Kreuzschlitten 28 bewegt wird, daß er am Kopierstift 24 entlangtastend in bekannter Weise längs des Profiles 6 der Profilschablone 1 geführt wird. In gleichem Maße schleift die Schleifscheibe 21 das Profil 26 im Profilmesser 9.Now, with the grinding wheel 21, the profile 26 in the profile knife 9 is produced in a known manner by moving the template carrier 10 with the grinding arbor 14 over the cross slide 28 in such a way that it gropes along the copy pin 24 in a known manner is guided along the profile 6 of the profile template 1. To the same extent, the grinding wheel 21 grinds the profile 26 in the profile knife 9.

Während des Schleifvorganges liegt die Profilschablone 1 mit ihrer Anschlagseite 4 an der Null-Scheibe 13 an. Das Profil 6 der Profilschablone 1 beginnt im Abstand 8 von der Anschlagseite 4, wie dies anhand von Fig.1 erläutert worden ist. Der Messerkopf 31 mit dem Lagerteil 32 ist so ausgebildet, daß der Anfang des Profiles 26 des Profilmessers 9 ebenfalls im Abstand 8 von der Seite 19 des Bundes 17 aus anfängt.During the grinding process, the profile template 1 rests with its stop side 4 on the zero disk 13. The profile 6 of the profile template 1 begins at a distance 8 from the stop side 4, as has been explained with reference to FIG. 1. The cutter head 31 with the bearing part 32 is designed such that the beginning of the profile 26 of the profile knife 9 also begins at a distance 8 from the side 19 of the collar 17.

Fig. 4 zeigt eine Ausführungsform eines Messerkopfes 31a, der nicht mit einem Lagerteil hydraulisch auf dem Spindelkopf 14 festgeklemmt wird. Der Messerkopf 31a wird vielmehr in herkömmlicher Weise auf dem Spindelkopf 14 befestigt. Da der Messerkopf 31a keinen überstehenden Lagerteil aufweist, liegt er mit seiner Stirnseite 34a unmittelbar an der Seite 19 des Bundes 17 an. Würde die Profilschablone 1 wie beim Ausführungsbeispiel nach Fig. 3 an einer Null-Scheibe anliegen, dann würde die Schleifscheibe 21 das Profil 26 am Profilmesser 9 in einem zu großen Abstand von der Seitenfläche 33 zu schleifen beginnen. Der Anfang des Profiles der Profilmesser würde dann, je nachdem, in welchem Messerkopf das Profilmesser bei der Profilherstellung eingespannt gewesen ist, mit unterschiedlichem Abstand von der Seitenfläche 33 beginnen. Aus diesem Grunde wird bei Verwendung des Messerkopfes 31a auf den Anschlagzapfen 12 keine Null-Scheibe aufgesetzt, sondern die Profilschablone 1 mit ihrer Anschlagseite 4 am Anschlagzapfen 12 zur Anlage gebracht. Der Abstand 35 zwischen den beiden Anschlagzapfen 12 entspricht der Länge 20 des Schleifdornes 14 zuzüglich dem Abstand 8, den der Anfang des Profiles 6 von der Anschlagseite 4 der Profilschablone 1 hat. Der Abstand 35 beträgt im Ausführungsbeispiel 245 mm und ist das Grundmaß des Schablonenträgers 10, wenn das Profilmesser 9 in dem Messerkopf 31a eingespannt ist. Beim Messerkopf 31 gemäß Fig. 3 ist das Grundmaß der Abstand 30 zwischen der auf die Anschlagzapfen 12 gesteckten Null-Scheibe 13. Dieses Grundmaß 30 entspricht der Länge 20 des Schleifdornes 14, die im Ausführungsbeispiel 225 mm beträgt. Bei der Einstellung gemäß Fig. 4 liegt der Anfang des Profiles 26 des Profilmessers 9 in einem Abstand 36 von der Seitenfläche 33. Der Abstand 36 ist genau halb so groß wie der Abstand 8. Somit beginnt der Profilanfang bei dem in den Messerkopf 31a eingespannten Profilmesser 9 mit dem Abstand 36 von der entsprechenden Seitenfläche 33. Bei der Einstellung der Schleifscheibe 21 ist allerdings die Null-Scheibe 13 auf den Anschlagzapfen 12 gesteckt, wie es anhand von Fig. 2 erläutert wird. Da der Messerkopf 31a keinen axial überstehenden Lagerteil hat, wird beim Schleifen der Profilmesser 9 die Null-Scheibe 13 als Ausgleich vom Lagerzapfen 12 abgenommen. Beim Verschieben des Schablonenträgers 10 bis zur Anlage der Profilschablone 1 am Anschlagzapfen 12 wird die Schleifscheibe 21 in gleichem Maße in die in Fig. 4 dargestellte Lage verschoben. Sie hat dann den Abstand 8 vom Anfang des Profiles 26 des Profilmessers 9. Die Profilschablone 1 verschiebt sich somit um die Wandstärke der Null-Scheibe 13. Dieses Maß ist gleichzeitig das Differenzmaß zwischen dem Abstand 8 und dem Abstand 36.FIG. 4 shows an embodiment of a cutter head 31a that is not hydraulically clamped on the spindle head 14 with a bearing part. Rather, the cutter head 31a is attached to the spindle head 14 in a conventional manner. Since the cutter head 31a has no protruding bearing part, its end face 34a lies directly against the side 19 of the collar 17. If, as in the exemplary embodiment according to FIG. 3, the profile template 1 were in contact with a zero wheel, then the grinding wheel 21 would start to grind the profile 26 on the profile knife 9 at too great a distance from the side surface 33. The beginning of the profile of the profile knives would then, depending on the cutter head in which the profile knife was clamped during the manufacture of the profile, start at a different distance from the side surface 33. For this reason, when using the cutter head 31a, no zero washer is placed on the stop pin 12, but the profile template 1 is brought into abutment with the stop side 4 on the stop pin 12. The distance 35 between the The two stop pins 12 correspond to the length 20 of the grinding arbor 14 plus the distance 8 that the beginning of the profile 6 has from the stop side 4 of the profile template 1. The distance 35 is 245 mm in the exemplary embodiment and is the basic dimension of the template carrier 10 when the profile knife 9 is clamped in the cutter head 31a. In the cutter head 31 according to FIG. 3, the basic dimension is the distance 30 between the zero disk 13 plugged onto the stop pin 12. This basic dimension 30 corresponds to the length 20 of the grinding arbor 14, which in the exemplary embodiment is 225 mm. 4, the start of the profile 26 of the profile knife 9 is at a distance 36 from the side surface 33. The distance 36 is exactly half as large as the distance 8. Thus, the beginning of the profile begins with the profile knife clamped in the cutter head 31a 9 with the distance 36 from the corresponding side surface 33. When adjusting the grinding wheel 21, however, the zero wheel 13 is placed on the stop pin 12, as will be explained with reference to FIG. 2. Since the cutter head 31a has no axially protruding bearing part, the zero disk 13 is removed from the journal 12 as compensation when grinding the profile knives 9. When the template carrier 10 is moved until the profile template 1 rests on the stop pin 12, the grinding wheel 21 is displaced to the same extent into the position shown in FIG. 4. It then has the distance 8 from the start of the profile 26 of the profile knife 9. The profile template 1 thus shifts by the wall thickness of the zero disk 13. This dimension is at the same time the difference between the distance 8 and the distance 36.

Die Messerköpfe 31, 31a werden nach der Herstellung der Profilmesser in eine (nicht dargestellte) Kehlmaschine eingesetzt. Je nachdem, in welchen Messerkopf das Profilmesser 9 eingespannt ist, wird die Kehlmaschine bzw. die entsprechende Spindel entsprechend dem unterschiedlichen Profilanfang 8 bzw. 36 axial auf dieses Maß eingestellt.The cutter heads 31, 31a are inserted into a moulder (not shown) after the production of the profile knives. Depending on the cutter head in which the profile cutter 9 is clamped, the moulder or the corresponding spindle is axially adjusted to this dimension in accordance with the different profile start 8 or 36.

Bei den Ausführungsbeispielen nach den Fig. 3 und 4 wird die Profilschablone 1 an die rechte Null-Scheibe 13 bzw. den rechten Anschlagzapfen 12 angelegt. Selbstverständlich kann die Profilschablone 1 auch an die linke Null-Scheibe bzw. den linken Anschlagzapfen angelegt werden. Dies hängt davon ab, wo der Messerkopf 31, 31a an der Kehlmaschine montiert wird. Linke und untere Profilmesser der Kehlmaschine werden linksseitig auf den Schleifdorn 14 und die rechts und oben liegenden Profilmesser der Kehlmaschine rechtsseitig auf den Schleifdorn 14 gespannt. Bei Verwendung des hydraulisch spannbaren Messerkopfes 31 wird auf den entsprechenden Anschlagzapfen 12 die Null-Scheibe 13 gesteckt, während bei Verwendung des Messerkopfes 31a ohne die Null-Scheibe 13 geschliffen wird. Sowohl bei der Neuanfertigung des Profilmessers 9 als auch bei einem Nachschleifvorgang muß nur noch der Werkzeugdurchmesser eingestellt werden. Ein seitliches, axiales Verstellen des Schablonenträgers 10 oder andere Korrekturen sind nicht notwendig. Dadurch kann das Profilmesser 9 einfach und genau hergestellt und/oder nachgeschliffen werden.In the exemplary embodiments according to FIGS. 3 and 4, the profile template 1 is applied to the right zero disk 13 or the right stop pin 12. Of course, the profile template 1 can also be placed on the left zero disc or the left stop pin. This depends on where the cutter head 31, 31a is mounted on the moulder. The left and lower profile knives of the moulder are clamped on the left on the grinding arbor 14 and the profile knives on the right and above on the right on the grinding arbor 14. When using the hydraulically tensionable cutter head 31, the zero disk 13 is placed on the corresponding stop pin 12, while when using the cutter head 31a, grinding is carried out without the zero disk 13. Both when making the profile knife 9 and when regrinding, only the tool diameter has to be set. Lateral, axial adjustment of the template carrier 10 or other corrections are not necessary. As a result, the profile knife 9 can be easily and precisely manufactured and / or reground.

Die Fig. 5 und 6 zeigen eine obere Horizontalspindel (Fig. 5) und eine rechte Vertikalspindel (Fig. 6) einer Kehlmaschine, die mit den Messerköpfen 31, 31a versehen wird. In Fig. 5 ist der Messerkopf 31 dargestellt, der hydraulisch auf der Horizontalspindel 37 festgespannt wird. Im Bereich unterhalb der Spindel 37 verläuft senkrecht zu ihr eine Anschlagkante 38 für die Führung des mit den Profilmessern 9 zu profilierenden Werkstückes. Der Messerkopf 31 trägt über seinen Umfang verteilt mehrere Profilmesser 9, die untereinander das gleiche Profil 26 haben. Die Spindel 37 hat eine Anlage 39, an der der Lagerteil 32 des Messerkopfes 31 zur Anlage kommt. Die Anschlagkante 38 befindet sich im Abstand 8 von der Anlage 39. Dieser Abstand 8 entspricht auch dem Abstand des Anfanges des Profiles 26 des Messers 9 von der am Spindelanschlag 39 anliegenden Anlagefläche 32ʹ des Lagerteiles 32. Da in der zuvor beschriebenen Weise das Profilmesser 9 so hergestellt worden ist, daß der Profilbeginn den Abstand 8 von der Stirnseite der Anlagefläche 32ʹ hat, läßt sich der Messerkopf 31 einfach auf der Spindel 37 lagegenau montieren. Er wird lediglich so weit aufgeschoben, bis die Anlagefläche 32ʹ am Spindelanschlag 39 zur Anlage kommt. Dann ist der Messerkopf 31 mit den Profilmessern 9 exakt gegenüber der Anschlagkante 38 ausgerichtet. Die Spindel 37 wird also auf das Axial-Grundmaß 8 hinter der Anschlagkante 38 eingestellt. Auf diese Weise werden sämtliche Spindeln der Kehlmaschine, die die Messerköpfe 31 tragen, relativ zur Anschlagkante ausgerichtet.5 and 6 show an upper horizontal spindle (FIG. 5) and a right vertical spindle (FIG. 6) of a moulder, which is provided with the cutter heads 31, 31a. 5 shows the cutter head 31 which is clamped hydraulically on the horizontal spindle 37. In the area below the spindle 37 runs vertically to it a stop edge 38 for guiding the workpiece to be profiled with the profile knives 9. The knife head 31 carries several profile knives 9 distributed over its circumference, which have the same profile 26 with one another. The spindle 37 has a system 39, on which the bearing part 32 of the cutter head 31 comes to rest. The stop edge 38 is located at a distance 8 from the system 39. This distance 8 also corresponds to the distance from the start of the profile 26 of the knife 9 from the contact surface 32 'of the bearing part 32 bearing against the spindle stop 39. Since the profile knife 9 in the manner described above has been made that the beginning of the profile has the distance 8 from the end face of the contact surface 32ʹ, the cutter head 31 can be mounted precisely on the spindle 37. It is only pushed open until the contact surface 32ʹ comes to rest on the spindle stop 39. Then the cutter head 31 with the profile cutters 9 is exactly aligned with the stop edge 38. The spindle 37 is thus set to the basic axial dimension 8 behind the stop edge 38. In this way, all the spindles of the moulder that carry the cutter heads 31 are aligned relative to the stop edge.

Wird auf die Spindeln der Kehlmaschine der Messerkopf 31a montiert, dann muß das Axial-Grundmaß 36 eingestellt werden, weil das Profil 26 des Profilmessers 9 in dem kleineren Abstand 36 von der Seitenfläche 33 beginnt (Fig. 4).If the cutter head 31a is mounted on the spindles of the moulder, then the basic axial dimension 36 must be set because the profile 26 of the profile knife 9 begins at the smaller distance 36 from the side surface 33 (FIG. 4).

Eine solche Einstellung bei Verwendung eines Messerkopfes 31a wird anhand von Fig. 6 erläutert. Der Messerkopf 31a sitzt auf der Vertikalspindel 40 und trägt über seinen Umfang verteilt in bekannter Weise die Profilmesser 9. Ihr Profil 26 befindet sich im Bereich oberhalb eines Tisches 41, auf dem die zu bearbeitenden (nicht dargestellten) Werkstücke am Messerkopf 31a vorbeigeführt werden. Wie anhand von Fig. 4 erläutert worden ist, liegt bei Verwendung der Messerköpfe 31a der Beginn des Profiles 26 der Profilmesser 9 in einem Abstand 36 von der Seitenfläche des Messerkopfes. Im dargestellten Ausführungsbeispiel wird ein Teil des Werkstückes vom Messerkopf und von den Profilmessern weggehobelt werden. Als Ausgleich hierfür ist ein Distanzring 42 vorgesehen, über dessen Zwischenlage der Messerkopf 31a an der Spindelanlage 39' anliegt. Somit wird durch den Distanzring 42 das erforderliche Grundmaß 36 am fertig bearbeitelen Werkstück genau eingehalten. In der Kehlmaschine können die Messerköpfe 31 und 31a auch zusammen eingesetzt werden, wobei entweder die entsprechenden Spindeln auf die unterschiedlichen Grundmaße 8 und 36 eingestellt werden müssen, oder mit gleichem Grundmaß 36 und einem Distanzring mit einem Differenzhöhenmaß der Grundmaße 36 und 8 für den Messerkopf 31a.Such a setting when using a cutter head 31a is explained with reference to FIG. 6. The cutter head 31a sits on the vertical spindle 40 and carries the profile knives 9 distributed over its circumference in a known manner. Your profile 26 is located in the area above a table 41 on which the (not shown) Workpieces are guided past the cutter head 31a. As has been explained with reference to FIG. 4, when using the cutter heads 31a, the beginning of the profile 26 of the profile cutters 9 lies at a distance 36 from the side surface of the cutter head. In the illustrated embodiment, part of the workpiece will be planed away from the cutter head and from the profile knives. To compensate for this, a spacer ring 42 is provided, over the intermediate layer of which the cutter head 31a bears against the spindle system 39 '. The required basic dimension 36 on the finished machined workpiece is thus exactly maintained by the spacer ring 42. In the moulder, the cutter heads 31 and 31a can also be used together, with either the corresponding spindles having to be set to the different basic dimensions 8 and 36, or with the same basic dimension 36 and a spacer ring with a differential height dimension of the basic dimensions 36 and 8 for the cutter head 31a .

Mit der Einrichtung lassen sich auch Joint-Steine sehr einfach und genau fertigen. Joint-Steine stellen eine Art Schleifsteine dar, die in die Kehlmaschine eingebaut werden und die ein dem jeweiligen Profilmesser 9 entsprechendes Gegenprofil haben. Mit den Joint-Steinen können die Profilmesser in der Kehlmaschine nachgeschliffen werden. Die Joint-Steine bestehen aus Siliciumcarbid für Profilwerkzeuge 9, die aus HSS und Stellit bestehen. Für Hartmetall-Profilmesser wird eine Diamant-Kunststoff-Einlage als Joint-Stein verwendet, die in einen Siliciumcarbidhalter eingebettet ist. Fig. 7 zeigt ein Gerät, mit dem das dem Profilmesser 9 entsprechende Gegenprofil am Joint-Stein äußerst genau und dabei sehr einfach hergestellt werden kann. Der Joint-Stein 43 wird zunächst vorbereitet. Hierzu wird er entsprechend der Profilbreite mit Hilfe der Profilschablone 1 angerissen und durch Schleifen oder Feilen vorprofiliert. Anschließend wird die so erhaltene Profilkontur 44 beidseitig angeschrägt.The device can also be used to manufacture joint stones very easily and precisely. Joint stones represent a kind of grindstones that are installed in the moulder and that have a counter profile corresponding to the respective profile knife 9. With the joint stones, the profile knives can be reground in the moulder. The joint stones consist of silicon carbide for profile tools 9, which consist of HSS and stellite. For carbide profile knives, a diamond-plastic insert is used as a joint stone, which is embedded in a silicon carbide holder. Fig. 7 shows a device with which the counter profile corresponding to the profile knife 9 on the joint stone can be produced extremely precisely and very easily. The joint stone 43 is first prepared. For this purpose, it is scribed according to the profile width using profile template 1 and pre-profiled by grinding or filing. The profile contour 44 thus obtained is then chamfered on both sides.

Der Joint-Stein 43 wird in einen Halter 45 eingeklemmt. der entsprechend dem späteren Werkzeugeinsatz rechts oder links in einer Einstellvorrichtung 46 befestigt wird. Sie hat eine Achse 47, auf die der Messerkopf 31 oder 31a mit den eingespannten Profilmessern 9 gesteckt wird. Der Messerkopf 31, 31a wird mit der Seite auf die Achse 47 aufgeschoben, mit der er in der Kehlmaschine an der entsprechenden Spindel 37, 40 anliegt (Fig. 5 und 6). Wird mit dem Messerkopf das Werkstück an seiner Anlageseite sauber gehobelt, wie dies anhand von Fig. 6 erläutert worden ist, dann wird zuvor auf die Achse 47 ein dem Distanzring 42 entsprechender Distanzring 48 auf die Achse 47 gesteckt. Der Distanzring 48 liegt auf einem Anschlag 49, dessen Oberseite die Bezugsebene 60 für den Messerkopf 31, 31a bzw. dessen Profilmesser 9 und für den Joint-Stein 43 bildet. Die Einstellvorrichtung 46 ist so ausgebildet, daß in bezug auf die Spindelanlage und den Anschlag des Halters 45 die gleichen Verhältnisse herrschen wie in der Kehlmaschine. Dadurch ist gewährleistet, daß die Genauigkeit bei dem im folgenden noch zu beschreibenden Einschaben des Joint-Steines 43 in der Einstellvorrichtung 46 ohne zusätzliche Korrekturen auf die Kehlmaschine übertragen werden kann.The joint stone 43 is clamped in a holder 45. which is fastened to the right or left in an adjusting device 46 according to the later use of tools. It has an axis 47, on which the cutter head 31 or 31a with the clamped profile knives 9 is placed. The knife head 31, 31a is pushed onto the axis 47 with the side with which it rests in the moulder on the corresponding spindle 37, 40 (FIGS. 5 and 6). If the workpiece is planed cleanly on its contact side with the cutter head, as has been explained with reference to FIG. 6, then a spacer ring 48 corresponding to the spacer ring 42 is placed on the axis 47 beforehand. The spacer ring 48 lies on a stop 49, the upper side of which forms the reference plane 60 for the cutter head 31, 31a or its profile cutter 9 and for the joint stone 43. The adjusting device 46 is designed so that the same conditions prevail with respect to the spindle system and the stop of the holder 45 as in the moulder. This ensures that the accuracy when the joint stone 43 is scraped into the adjusting device 46, which will be described below, can be transferred to the moulder without additional corrections.

Der auf der Achse 47 sitzende Messerkopf wird mit einer Klemmeinrichtung 50 festgeklemmt.The knife head seated on the axis 47 is clamped with a clamping device 50.

Der Halter 45 hat Klemmbacken 51, 52, zwischen die der Joint-Stein 43 eingespannt werden kann. Die Klemmbacken 51, 52 sind mittels einer Verstelleinrichtung 53 in Achsrichtung des Messerkopfes verstellbar. Sie hat eine in den Klemmbacken 51 vorgesehene Stellschraube 54, die sich auf einem Anschlag 55 des Halters 45 abstützt. Die Stellschraube 54 wird in der eingestellten Lage mittels einer Kontermutter 56 gesichert. Der Anschlag 55 wird durch den Kopf einer weiteren Stellschraube 57 gebildet, die in den Kalter 45 geschraubt und mit einer Kontermutter 58 gesichert wird. Die Stellschrauben 54, 57 mit den Kontermuttern 56, 58 bilden die Verstelleinrichtung 43. Die Stellschraube 57 wird so eingestellt, daß ihr Kopf 55 einen Abstand 59 von der die Oberseite des Anschlages 49 enthaltenden Bezugsebene 60 hat. Dieser Abstand 59 ist so auf den Abstand 8 abgestimmt, daß der Beginn des Profiles des Joint-Steines 43 ebenso wie der Anfang des Profiles 26 der Profilmesser 9 im gleichen Abstand von der Bezugsebene 60 liegt.The holder 45 has clamping jaws 51, 52, between which the joint stone 43 can be clamped. The clamping jaws 51, 52 can be adjusted in the axial direction of the cutter head by means of an adjusting device 53. It has a set screw 54 provided in the clamping jaws 51, which is supported on a stop 55 of the holder 45. The set screw 54 is in the set position by means of a Lock nut 56 secured. The stop 55 is formed by the head of a further set screw 57, which is screwed into the cold 45 and secured with a lock nut 58. The set screws 54, 57 with the lock nuts 56, 58 form the adjusting device 43. The set screw 57 is set so that its head 55 is at a distance 59 from the reference plane 60 containing the upper side of the stop 49. This distance 59 is matched to the distance 8 that the start of the profile of the joint stone 43 as well as the start of the profile 26 of the profile knife 9 is at the same distance from the reference plane 60.

Die exakte Lage des Halters 45 bzw. des Joint-Steines 43 wird in bezug auf das Profil 26 der Profilmesser 9 vermittelt und so eingestellt, daß das Profil des vorbereiteten Joint-Steines 43 so genau wie möglich zum Profil 26 der Profilmesser 9 liegt. Anschließend wird ein den Halter 45 aufnehmender Schlitten 61 der Einstellvorrichtung 46 in Pfeilrichtung 62 quer zur Achse 47 zugestellt. Der Messerkopf 31, 31a wird nun gedreht, wobei die Profilmesser 9 den Joint-Stein 43 abschaben, bis das Profil des Joint-Steines 43 genau mit dem Profil 26 der Profilmesser übereinstimmt. Nach diesem Einschabvorgang werden der Halter 45 mit dem Joint-Stein 43 und der Messerkopf 31, 31a in die Kehlmaschine eingebaut.The exact position of the holder 45 or the joint stone 43 is conveyed with respect to the profile 26 of the profile knife 9 and set so that the profile of the prepared joint stone 43 lies as precisely as possible with the profile 26 of the profile knife 9. A carriage 61 receiving the holder 45 of the adjusting device 46 is then advanced in the direction of the arrow 62 transversely to the axis 47. The knife head 31, 31a is now rotated, the profile knives 9 scraping the joint stone 43 until the profile of the joint stone 43 exactly matches the profile 26 of the profile knives. After this scraping process, the holder 45 with the joint stone 43 and the cutter head 31, 31a are installed in the moulder.

Fig. 8 zeigt den Halter 45 mit dem genau profilierten Joint-Stein 43 sowie den zugehörigen Messerkopf in der Kehlmaschine. Der Messerkopf 31 bzw. 31a wird auf die entsprechende Spindel 37 der Kehlmaschine so weit aufgeschoben, bis die Anlagefläche 32ʹ des Lagerteiles 32 an der Spindelanlage 39 zur Anlage kommt. Hat der Messerkopf keinen Lagerteil 32, dann wird er mit seiner einen Seite unmittelbar zur Anlage an der Spindelanlage 39 gebracht, wie es anhand von Fig. 6 erläutert worden ist. Der Messerkopf 31, 31a nimmt dann in bezug auf die Spindel 37 die anhand von Fig. 5 erläuterte Lage ein. Der Anfang des Profiles 26 der Profilmesser 9 liegt im Abstand 8 von der Spindelanlage 39. Dieser Spindelanlage 39 entspricht in der Einstellvorrichtung 46 die Bezugsebene 60.8 shows the holder 45 with the precisely profiled joint stone 43 and the associated cutter head in the moulder. The cutter head 31 or 31a is on the corresponding Spindle 37 of the moulder pushed so far until the contact surface 32ʹ of the bearing part 32 comes to rest on the spindle system 39. If the cutter head has no bearing part 32, then one side of it is brought directly into contact with the spindle system 39, as has been explained with reference to FIG. 6. The cutter head 31, 31a then assumes the position explained with reference to FIG. 5 with respect to the spindle 37. The beginning of the profile 26 of the profile knives 9 is at a distance 8 from the spindle system 39. This spindle system 39 corresponds to the reference plane 60 in the setting device 46.

Der Halter 45 mit dem Joint-Stein 43 wird in eine entsprechende Aufnahme der Kehlmaschine bis auf Anschlag eingeschoben. Dieser (nicht dargestellte) Anschlag ist so vorgesehen, daß der Anfang des Profiles 44 des Joint-Steines 43 ebenfalls den Abstand 8 von der die Spindelanlage 39 enthaltenden Ebene hat. Dadurch hat der Anschlag 55 der Verstelleinrichtung 53 von der den Profilanfang enthaltenden Ebene 63 den Abstand 64. Somit ergibt der Abstand 64 und der Abstand 8 das Abstandsmaß 59 (Fig. 7) in der Einstellvorrichtung 46. Da der Joint-Stein 43 und die Profilmesser 9 schon zuvor genau eingestellt worden sind, ist es nur noch notwendig, den Halter 45 und den jeweiligen Messerkopf 31, 31a bis auf Anschlag auf die entsprechenden Spindeln der Kehlmaschine aufzuschieben und dann in bekannter Weise axial zu sichern. Der Halter 45 ist in bekannter Weise in der Kehlmaschine fixiert. Somit ist gewährleistet, daß bei einem Wechsel des Joint-Steines mit dem entsprechenden Halter, beispielsweise beim Wechsel von einem Profiljoint-Stein auf einen Geradjoint-Stein und zurück, dieses beschriebene Anschlagmaß immer gleich bleibt. Nach dem Verschrauben des Halters 45 in der Kehlmaschine ist durch die Genauigkeit beim Einstellen in der Einstellvorrichtung 46 allenfalls nur noch ein leichtes Nachschaben des Joint-Steines 43 erforderlich. Ein axiales Verstellen der Spindel 37 der Kehlmaschine ist nicht mehr erforderlich.The holder 45 with the joint stone 43 is pushed into a corresponding receptacle of the moulder up to the stop. This (not shown) stop is provided so that the beginning of the profile 44 of the joint stone 43 is also at a distance 8 from the plane containing the spindle system 39. As a result, the stop 55 of the adjusting device 53 is at a distance 64 from the plane 63 containing the beginning of the profile. Thus, the distance 64 and the distance 8 give the distance dimension 59 (FIG. 7) in the adjusting device 46. Since the joint stone 43 and the profile knife 9 have already been precisely set, it is only necessary to push the holder 45 and the respective cutter head 31, 31a as far as it will go onto the corresponding spindles of the moulder and then to axially secure them in a known manner. The holder 45 is fixed in the moulder in a known manner. This ensures that when changing the joint stone with the appropriate holder, for example when changing from a profile joint stone to a straight joint stone and back, this described stop dimension is always the same remains. After screwing the holder 45 in the moulder, due to the accuracy when setting in the setting device 46, only a slight re-scraping of the joint stone 43 is required. An axial adjustment of the spindle 37 of the moulder is no longer necessary.

Im Ausführungsbeispiel gemäß Fig. 8 wird das zu bearbeitende Werkstück 65 unterhalb des Messerkopfes 31, 31a hindurchgeführt und mit den Profilmessern 9 profiliert. Das Profil 26 der Messer 9 wird mit dem Joint-Stein 43 bei voller Drehzahl des Messerkopfes 31, 31a nachgeschliffen, wobei der Joint-Stein jeweils geringfügig zugestellt wird.In the exemplary embodiment according to FIG. 8, the workpiece 65 to be machined is passed beneath the cutter head 31, 31a and profiled with the profile knives 9. The profile 26 of the knives 9 is reground with the joint stone 43 at full speed of the knife head 31, 31a, the joint stone being slightly advanced in each case.

Wenn die Profilmesser 9ʹ (Fig. 9) senkrechte Schneiden 66 haben, dann wird beim Nachschärfen die durch die Schneiden 66 bestimmte Bearbeitungsebene axial verändert. Um den Schleifabtrag X zum Schärfen zur Verfügung zu haben, wird ein Ausgleichsring 67 vorgesehen, der ebenfalls die Dicke X hat und auf die Spindel 37 gesteckt wird. Der Messerkopf 31, 31a liegt dann unter Zwischenlage dieses Ausgleichsringes 67 an der Spindelanlage 39 an. Durch diesen Ausgleichsring 67 wird das Lösen bzw. Versetzen der Profilmesser 9ʹ im Messerkopf 31, 31a einige Male eingespart. Es können verschieden dicke Ausgleichsringe 67 verwendet werden, die vorzugsweise magnetisch aufgelegt werden. Dies hat Vorteile für den Transport von der Schärfeinrichtung zur Kehlmaschine.If the profile knives 9ʹ (FIG. 9) have vertical cutting edges 66, then the working plane determined by the cutting edges 66 is changed axially during re-sharpening. In order to have the grinding removal X available for sharpening, a compensating ring 67 is provided, which also has the thickness X and is placed on the spindle 37. The cutter head 31, 31a then lies against the spindle system 39 with the interposition of this compensating ring 67. This compensating ring 67 saves the loosening or displacement of the profile knives 9ʹ in the cutter head 31, 31a a few times. Compensation rings 67 of different thicknesses can be used, which are preferably placed magnetically. This has advantages for the transport from the sharpening device to the moulder.

Die Halter 45 können zum schnellen Ein- und Ausbau mit Schlüssellöchem versehen werden, so daß die Schrauben, mit denen die Halter lösbar befestigt werden, nicht vollständig gelöst werden müssen. Diese Befestigungsschrauben werden lediglich gelockert, sodaß der Halter 45 gegenüber den Befestigungsschrauben so weit verschoben werden kann, daß die weiteren Öffnungsabschnitte der Schlüssellöcher im Bereich des Schraubenkopfes liegen. Die Halter 45 können dann von den Befestigungsschrauben einfach abgezogen werden.The holder 45 can be provided with keyholes for quick installation and removal, so that the screws with which the holders are releasably attached, do not have to be completely detached. These fastening screws are only loosened so that the holder 45 can be displaced relative to the fastening screws so far that the further opening sections of the keyholes are in the area of the screw head. The holder 45 can then be easily removed from the mounting screws.
