Description

Die vorliegende Erfindung betrifft eine Garnitur für eine Karde oder Krempel zur Bearbeitung von Textilfasern, aufweisend einen Sägezahndraht mit in Drahtlaufrichtung hintereinander ausgebildeten Zähnen, wobei die Zähne ein sich über einem Zahnfuß erstreckendes Oberprofil aufweisen, das wenigstens gebildet ist aus dem Konturverlauf eines Zahnrückens und einer Zahnbrust.The present invention relates to a clothing for a carding or carding machine for processing textile fibers, comprising a sawtooth wire in the wire running direction behind one another teeth, the teeth have a over a tooth root extending upper profile, which is at least formed from the contour of a tooth back and a tooth face ,

Aus der DE 102 54 918 A1 ist eine Garnitur für eine Karde oder Krempel zur Bearbeitung von Textilfasern bekannt, aufweisend einen Sägezahndraht mit in Drahtlaufrichtung hintereinander ausgebildeten Zähnen, wobei die Zähne ein sich über einem Zahnfuß erstreckendes Oberprofil aufweisen, das wenigstens gebildet ist aus dem Konturverlauf eines Zahnrückens und einer Zahnbrust. Der Zahnrücken geht dabei über in eine im Wesentlichen flach ausgebildete Kopffläche, und die Kopffläche mündet in einer Zahnspitze, an die sich unterseitig die Zahnbrust anschließt. Die Kopffläche bildet dabei eine Kardierfläche, die das bearbeitete Fasermaterial in den Kardierbereich hebt und in diesem hält. Der Kardierbereich bildet dabei den Dachbereich des Oberprofils und wirkt mit der Garnitur einer weiteren Walze oder mit Garniturdeckeln, sogenannten Wanderdeckeln, zusammen.From the DE 102 54 918 A1 a set for a card or carding machine for processing textile fibers is known, comprising a sawtooth wire in the wire running direction behind one another teeth, the teeth have a over a tooth root extending upper profile, which is at least formed from the contour of a tooth back and a tooth face. The tooth back goes over into a substantially flat head surface, and the head surface opens into a tooth tip, which is followed by the lower side of the tooth face. The top surface forms a carding surface that lifts the processed fiber material in the carding and holds in this. The carding area forms the roof area of the upper profile and cooperates with the clothing of another roller or with clothing covers, so-called moving lids.

Durch die betonte Ausprägung der Kardierflächen auf der Oberseite der Zähne ergeben sich nachteilhafterweise schlechtere Eigenschaften bei der Ausscheidung von Nissen, Noppen und/oder Schalennissen im Fasermaterial, insbesondere wird die Auflösung von Faserbatzen und die Ausreinigung der Fasern negativ beeinträchtigt.Due to the pronounced expression of the carding surfaces on the upper side of the teeth, disadvantageously poorer properties result in the excretion of nits, nubs and / or shawls in the Fiber material, in particular, the resolution of fiber patches and the cleaning of the fibers is adversely affected.

Die EP 0138778 offenbart eine Garnitur für einen Deckelstab, der als Drahtsegment in den Deckelstab eingeschoben wird. Ein Zahnsegement weist einen positiven Brustwinkel auf, während das andere Zahnsegment einen negativen Brustwinkel aufweist.The EP 0138778 discloses a set for a flat bar, which is inserted as a wire segment in the flat bar. One dental segment has a positive breast angle, while the other tooth segment has a negative breast angle.

Auch die GB2165561 offenbart eine Garnitur mit unterschiedlich hohen Zähnen, die keine Kardierfläche aufweisen und deren Spitzen in unterschiedliche Richtungen orientiert sind.Also the GB2165561 discloses a set of teeth of different heights, which have no carding surface and the tips are oriented in different directions.

In der DE 1927049 wird ein Garniturendraht mit einem Doppelzahn offenbart, die keine Kardierfläche aufweisen.In the DE 1927049 discloses a garment wire with a double tooth, which have no carding.

Und auch die US 5,655,262 offenbart einen Garniturendraht mit Zahnspitzen, die in unterschiedliche Richtungen orientiert sind. Ein Zahnsegement weist einen positiven Brustwinkel auf, während das andere Zahnsegment einen negativen Brustwinkel aufweist.And also the US 5,655,262 discloses a garment wire with tooth tips oriented in different directions. One dental segment has a positive breast angle, while the other tooth segment has a negative breast angle.

Die CH 467 349 A beschreibt eine Garnitur für eine Karde zur Bearbeitung von Textilfasern, aufweisend einen Sägezahndraht mit in Drahtlaufrichtung hintereinander ausgebildeten Zähnen. Die Zähne sind zueinander gleich gerichtet und dazu bestimmt, mit einem oder mehreren Gegenorganen zur Behandlung von Fasermaterial zusammenzuwirken, und die zwischen den Zähnen befindlichen Einschnitte verlaufen unterschiedlich tief. Damit zeigt der Sägezahndraht unterschiedliche sogenannte Einschlagtiefen, die Oberprofile der Zähne sind hingegen gleich zueinander ausgebildet. Die unterschiedlichen Einschlagtiefen sollen dazu dienen, kleinere und zugleich größere Faserbündel wirksam und schonend zu bearbeiten. Insbesondere ermöglichen die eher spitz ausgeführten Zähne ohne Kardierfläche eine sehr gute Auflösung der Faserbatzen beispielsweise bis zur Einzelfaser und die Ausreinigung der Fasern wird verbessert. Nachteilhafterweise ergibt sich jedoch eine schlechtere Kardierwirkung, da das Heben und Halten des Fasermaterials in den Kardierbereich nicht vorteilhaft ermöglicht wird.The CH 467 349 A describes a set for a carding machine for processing textile fibers, comprising a sawtooth wire in the wire running direction behind one another teeth. The teeth are equally directed and intended to cooperate with one or more counter-organs for the treatment of fibrous material, and the incisions located between the teeth are at different depths. Thus, the sawtooth shows different so-called Einschlagtiefen, the upper profiles of the teeth, however, are formed equal to each other. The different depths of impact are intended to work smaller and larger fiber bundles effectively and gently. In particular, allow the more pointed teeth without Kardierfläche a very good resolution of the fiber pats, for example, to the individual fiber and the cleaning of the Fibers is improved. Disadvantageously, however, results in a poorer carding, since the lifting and holding the fiber material in the carding is not advantageously possible.

Aufgabe der Erfindung ist die Weiterbildung einer Garnitur für eine Karde oder Krempel zur Bearbeitung von Textilfasern mit einem verbesserten Sägezahndraht. Insbesondere soll ein Sägezahndraht bereitgestellt werden, der eine besonders gute Kardierwirkung erzielt, zugleich soll die Auflösung von Faserbatzen insbesondere bis zur Einzelfaser und die Ausreinigung der Faserbatzen verbessert werden. Desweiteren soll die Garnitur und die mit der Garnitur ausgestattete Karde oder Krempel für verschiedene Faserarten und Faserqualitäten universell einsetzbar sein. Diese Aufgabe wird ausgehend von einer Garnitur für eine Karde oder Krempel zur Bearbeitung von Textilfasern gemäß dem Oberbegriff des Anspruches 1 mit den jeweils kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The object of the invention is the development of a set for a card or carding machine for processing textile fibers with an improved sawtooth. In particular, a sawtooth wire is to be provided, which achieves a particularly good carding effect, at the same time the resolution of fiber patches, in particular to the individual fiber and the cleaning of the fiber pats, should be improved. Furthermore, the set and equipped with the set carding or carding for various types of fibers and fiber qualities should be universally applicable. This object is achieved starting from a set for a card or carding machine for processing textile fibers according to the preamble of claim 1 with the respective characterizing features. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung schließt zur Bildung der Garnitur die technische Lehre ein, dass erste Zähne mit einem ersten Oberprofil und zweite Zähne mit einem vom ersten Oberprofil abweichenden zweiten Oberprofil in Drahtlaufrichtung abwechselnd auf dem Sägezahndraht ausgebildet sind. Kern der Erfindung ist die Ausbildung des Sägezahndrahtes mit Zähnen, die ein voneinander abweichendes und zu jeweiligen Vorteilen führendes Oberprofil aufweisen, und es sollen erste Zähne mit einem ersten Oberprofil und zweite Zähne mit einem zweiten, vom ersten Oberprofil abweichenden Oberprofil vorgesehen sein, die abwechselnd nacheinander entlang der Drahtlaufrichtung auf dem Sägezahndraht ausgebildet sind. Dadurch wird der Vorteil erreicht, dass die ersten Zähne mit dem ersten Oberprofil eine erste spezifische Funktion erfüllen und die zweiten Zähne mit dem zweiten Oberprofil erfüllen eine zweite spezifische Funktion. Die erste spezifische Funktion kann dabei beispielsweise das Heben und Halten des Fasermaterials im Kardierbereich betreffen, und die zweite spezifische Funktion kann eine bessere Auflösung des Fasermaterials betreffen, beispielsweise bis zur Auflösung einer Einzelfaser, wobei auch eine verbesserte Ausreinigung des Fasermaterials mit der zweiten spezifischen Funktion umfasst sein kann. Im Ergebnis wird ein besonders vorteilhafter Sägezahndraht bereitgestellt, der nicht nur in einer spezifischen Funktion optimiert ist, sondern in beispielsweise zwei oder mehreren spezifischen Funktionen.The invention includes the formation of the set the technical teaching that first teeth are formed with a first top profile and second teeth with a deviating from the first top profile second top profile in the wire direction alternately on the sawtooth. The core of the invention is the formation of the sawtooth wire with teeth having a different and leading to respective advantages top profile, and it should be provided first teeth with a first top profile and second teeth with a second, deviating from the first top profile top profile, alternately successively are formed along the wire running direction on the sawtooth wire. This achieves the advantage that the first teeth meet with the first top profile a first specific function and the second teeth with the second top profile fulfill a second specific function. The first specific function may relate, for example, to the lifting and holding of the fiber material in the carding area, and the second specific function may relate to a better dissolution of the fiber material, for example until the disintegration of a single fiber, wherein an improved cleaning of the fiber material with the second specific function also comprises can be. As a result, a particularly advantageous sawtooth wire is provided which is optimized not only in a specific function but in, for example, two or more specific functions.

Insbesondere ergibt sich in überraschender Weise eine gegenseitige Begünstigung der jeweiligen vorteilhaften Wirkungen der beiden Oberprofile der Zähne, denn es wurde festgestellt, dass der lange Zahnrücken die Fasern an der Oberfläche hält und eine optimale Auskardierung über den Wanderdeckel erzeugen kann. Hingegen gewährleistet der spitze Zahn gleichzeitig eine weitere Öffnung des Fasermaterials, wodurch die Auskardierung wiederum begünstigt wird. Dadurch wird eine schonende Öffnung und Auflösung bis zur Einzelfaser in verbesserter Form erreicht, dies geschieht bei gleichzeitig optimaler Ausreinigung und Nissenreduktion bis hin zur Nissenauflösung.In particular, there is surprisingly a reciprocal advantage of the respective advantageous effects of the two upper profiles of the teeth, because it was found that the long tooth back holds the fibers on the surface and can produce an optimal Auskardierung on the revolving lid. In contrast, the pointed tooth simultaneously ensures a further opening of the fiber material, whereby the Auskardierung is in turn favored. As a result, a gentle opening and resolution to the individual fiber is achieved in an improved form, this is done at the same time optimal cleaning and Nissenreduktion up to the Nissenauflösung.

Dabei weist das Oberprofil des ersten Zahns eine größere Kardierfläche auf und das Oberprofil des zweiten Zahns weist eine kleinere Kardierfläche auf. Dadurch unterscheiden sich die Oberprofile der zwei zueinander benachbarten Zähne voneinander und bilden ein Zähnepaar, welches sich entlang des Sägezahndrahtes nahezu unendlich oft wiederholt.In this case, the upper profile of the first tooth has a larger carding surface and the upper profile of the second tooth has a smaller carding surface. As a result, the upper profiles of the two mutually adjacent teeth differ from each other and form a pair of teeth, which is repeated almost infinitely repeated along the sawtooth wire.

Während das Oberprofil des ersten Zahns eine Kardierfläche aufweisen kann, kann vorgesehen sein, dass das Oberflächenprofil des zweiten Zahns dadurch bestimmt ist, dass der Zahnrücken und die Zahnbrust unter Bildung einer Zahnspitze aufeinander zulaufen, wodurch sich keine oder nur eine sehr kleine Kardierfläche ergibt und sich damit die Oberprofile der zwei zueinander benachbarten Zähne voneinander unterscheiden.While the upper profile of the first tooth may have a carding surface, it may be provided that the surface profile of the second Zahns is determined by the fact that the tooth back and the tooth face converge to form a tooth tip, resulting in no or only a very small carding and thus the upper profiles of the two mutually adjacent teeth differ from each other.

Die kleinere Kardierfläche des zweiten Zahns kann so viel kleiner ausgeführt sein, dass die kleinere Kardierfläche nahezu unendlich klein wird, sodass der Zahnrücken unter Bildung der Zahnspitze unmittelbar in die Zahnbrust übergeht. Beispielsweise kann aber die Kardierfläche des zweiten Zahns dann als eine sehr kleine Fläche ausgebildet sein, wenn die Garnitur bereits wenigstens einmal überschliffen wurde. Folglich muss das Oberprofil des zweiten Zahns nicht zwangsläufig spitz ausfallen, das Oberprofil des zweiten Zahns unterscheidet sich jedoch deutlich vom Oberprofil des ersten Zahns dadurch, dass die Länge der Kardierfläche des zweiten Zahns deutlich kürzer ausfällt als die Länge der Kardierfläche des ersten Zahns mit Bezug auf die Drahtlaufrichtung. Gemäß einer nicht erfinderischgemäßen Ausführungsform kann das Oberprofil des zweiten Zahns auch frei von einer Kardierfläche ausgebildet sein.The smaller carding surface of the second tooth can be designed so much smaller that the smaller carding is almost infinitely small, so that the tooth back goes to form the tooth tip directly into the tooth face. For example, however, the carding surface of the second tooth can then be designed as a very small area if the clothing has already been ground at least once. Consequently, the top profile of the second tooth need not necessarily be pointed, but the top profile of the second tooth differs significantly from the top profile of the first tooth in that the length of the carding surface of the second tooth is significantly shorter than the length of the carding surface of the first tooth with respect to the wire running direction. According to a non-inventive embodiment, the upper profile of the second tooth may also be formed free of a carding surface.

Ein weiterer Vorteil ergibt sich, wenn die Höhe des Oberprofils des ersten Zahns über dem Zahnfuß und die Höhe des Oberprofils des zweiten Zahns über dem Zahnfuß zueinander gleich ausgebildet sind. Damit weisen alle Zähne die gleiche Zahnhöhe auf, insbesondere können alle Zähne auch die gleiche Einschlagtiefe aufweisen, indem der Zahnfuß des ersten Zahns und der Zahnfuß des zweiten Zahns eine zueinander gleiche Einschlagtiefe aufweisen. Auch ist es denkbar, dass der Sägezahndraht eine in Drahtlaufrichtung konstante Schulterhöhe aufweist, zu der die Zahnfüße zwischen allen Zähnen eine gleiche Höhe aufweisen.Another advantage is obtained if the height of the upper profile of the first tooth above the tooth root and the height of the upper profile of the second tooth above the tooth root are identical to one another. Thus, all teeth have the same tooth height, in particular all teeth can also have the same depth of impact by the tooth root of the first tooth and the tooth root of the second tooth have an identical depth of impact. It is also conceivable for the sawtooth wire to have a shoulder height which is constant in the wire running direction and to which the toothed feet have the same height between all teeth.

Der erste Zahn weist eine Zahnbrust mit einem Brustwinkel auf, und der zweite Zahn weist eine Zahnbrust mit einem Brustwinkel auf, wobei die Brustwinkel beider Zähne vorteilhafterweise zueinander gleich ausgebildet sind. Insbesondere weisen die ersten und die zweiten Zähne positive Brustwinkel auf, sodass der Brustkonturverlauf mit dem Rückenkonturverlauf korrespondiert und nicht gegenläufig mit diesem ausgeführt ist.The first tooth has a tooth face with a breast angle, and the second tooth has a tooth face with a breast angle, wherein the breast angles of both teeth are advantageously identical to one another. In particular, the first and the second teeth have positive breast angles, so that the contour of the breast contour corresponds to the contour of the back contour and is not executed counter to it.

Die Garnitur kann schließlich noch dafür ausgebildet sein, den Hauptzylinder der Karde oder der Krempel zu bekleiden. Weiterhin kann die Garnitur zur Bekleidung des Vorreißers der Karde oder Krempel ausgebildet sein, wobei auch weitere Anwendungen der Garnitur gemäß der vorliegenden Erfindung denkbar sind.Finally, the clothing can be designed to clothe the master cylinder of the card or card. Furthermore, the clothing may be designed for clothing the lickerin of the carding machine or carding machine, whereby further applications of the clothing according to the present invention are conceivable.

Die Erfindung bezieht sich weiterhin auf eine Krempel mit einer Garnitur zur Bearbeitung von Textilfasern, wobei mit der Krempel im Sinne der vorliegenden Erfindung auch eine Karde mit umfasst ist, sodass die Garnitur auch zur Bearbeitung von Textilfasern durch eine Karde Anwendung finden kann. Die Garnitur der Krempel weist dabei einen Sägezahndraht mit in Drahtlaufrichtung hintereinander ausgebildeten Zähnen auf, wobei die Zähne ein sich über einem Zahnfuß erstreckendes Oberprofil aufweisen, das wenigstens gebildet ist aus dem Konturverlauf eines Zahnrückens und einer Zahnbrust, und erfindungsgemäß ist vorgesehen, dass erste Zähne mit einem ersten Oberprofil und zweite Zähne mit einem vom ersten Oberprofil abweichenden zweiten Oberprofil in Drahtlaufrichtung abwechselnd auf dem Sägezahndraht ausgebildet sind.The invention further relates to a carding machine with a garnish for processing textile fibers, wherein with the carding in the context of the present invention, a carding machine is also included, so that the garniture can also be used for processing textile fibers by a carding machine. The set of carding in this case has a sawtooth wire in the wire running direction successively formed teeth, the teeth have a over a tooth root extending upper profile, which is at least formed from the contour of a tooth back and a tooth face, and the invention is provided that first teeth with a first upper profile and second teeth are formed with a deviating from the first upper profile second upper profile in the wire running direction alternately on the sawtooth wire.

Die weiteren Merkmale und zugeordneten Vorteile, die vorstehend in Zusammenhang mit der erfindungsgemäßen Garnitur aufgeführt sind, finden für die Krempel mit der Garnitur ebenfalls Anwendung und Berücksichtigung.The further features and associated advantages, which are listed above in connection with the clothing according to the invention, also find application and consideration for the carding with the clothing.

Distributed over the circumference of the main cylinder 20 a plurality of turning rollers 25 and associated work rolls 26 are arranged. The formed web 24 is removed via a doffer roller 22 from the master cylinder 20.

Die nachfolgend mit den Figuren 2, 3 und 4 beschriebene Garnitur kann auf dem Hauptzylinder 20, auf dem Vorreißer 21 und gegebenenfalls auch auf den Wendewalzen 25, den Arbeitswalzen 26 und der Abnehmerwalze 22 angeordnet sein, wobei nur beispielshaft eine Krempel 1 gezeigt ist und die Garnitur gemäß der Erfindung kann auf gleiche Weise auch für verschiedene Walzen einer Karde Verwendung finden.The following with the FIGS. 2, 3 and 4 can be arranged on the master cylinder 20, on the lickerins 21 and optionally also on the turning rolls 25, the work rolls 26 and the take-off roll 22, wherein only an example of a carding 1 is shown and the clothing according to the invention can be applied in the same way for to use different rolls of a card.

Figur 2 zeigt in einer Seitenansicht einen Ausschnitt eines Sägezahndrahtes 10 einer erfindungsgemäßen Garnitur mit einer Anzahl von Zähnen, wobei erste Zähne 12 abwechselnd mit zweiten Zähnen 13 auf der Oberseite des Sägezahndrahtes 10 ausgebildet sind. Der Sägezahndraht 10 weist eine Drahtlaufrichtung 11 auf, und die ersten Zähne 12 mit einem ersten Oberprofil 15a und die zweiten Zähne 13 mit einem zweiten Oberprofil 15b, das sich vom ersten Oberprofil 15a unterscheidet, sind wechselweise aufeinander folgend in Drahtlaufrichtung 11 auf dem Sägezahndraht 10 ausgebildet. FIG. 2 shows a side view of a section of a sawtooth wire 10 of a set according to the invention with a number of teeth, wherein first teeth 12 are formed alternately with second teeth 13 on the upper side of the sawtooth wire 10. The sawtooth wire 10 has a wire running direction 11, and the first teeth 12 with a first top profile 15a and the second teeth 13 with a second top profile 15b, which differs from the first top profile 15a are formed alternately successively in the wire running direction 11 on the sawtooth wire 10 ,

Die ersten Zähne 12 weisen ein erstes Oberprofil 15a auf, und das erste Oberprofil 15a weist einen Zahnrücken 16 auf, der dem Bereich des Zahnfußes 14 folgt. Auf den Zahnrücken 16 folgt eine Kardierfläche 18, und die Kardierfläche 18 geht unter Bildung einer Zahnspitze 19 über in die Zahnbrust 17. Auf die Zahnbrust 17 folgt ein weiterer Zahnfuß 14, der in den Zahnrücken 16 des zweiten Zahnes 13 mit dem zweiten Oberprofil 15b übergeht.The first teeth 12 have a first upper profile 15a, and the first upper profile 15a has a tooth back 16 which follows the region of the tooth root 14. The tooth back 16 is followed by a carding surface 18, and the carding surface 18 merges into the tooth face 17 to form a tooth tip 19. The tooth face 17 is followed by another tooth root 14, which merges into the tooth back 16 of the second tooth 13 with the second top profile 15b ,

Das zweite Oberprofil 15b unterscheidet sich im Konturverlauf vom ersten Oberprofil 15a in der Kardierfläche 18'. Der Zahnrücken 16 geht zur Bildung des zweiten Zahnes 13 in eine Kardierfläche 18' über, die sehr klein ausgebildet ist, sodass der zweite Zahn 13 ein im Wesentlichen spitz ausgebildetes zweites Oberprofil 15b aufweist. Unter Bildung der Zahnspitze 19 geht die sehr klein ausgebildete Kardierfläche 18' in die Zahnbrust 17 über. Zwischen der Kardierfläche 18' und der Vertikalen, die senkrecht zur Drahtlaufrichtung 11 steht, bildet die Brustfläche der Zahnbrust 17 einen Brustwinkel β, wobei der Brustwinkel β des zweiten Zahnes 13 mit dem Brustwinkel β des ersten Zahns 12 übereinstimmt.The second upper profile 15b differs in the contour from the first upper profile 15a in the carding 18 '. The tooth back 16 is used to form the second tooth 13 in a carding 18 ', which is very small, so that the second tooth 13 has a substantially pointed trained second top profile 15 b. Forming the tooth tip 19 is the very small educated Carding 18 'in the tooth face 17 via. Between the carding surface 18 'and the vertical, which is perpendicular to the wire running direction 11, the breast surface of the tooth face 17 forms a breast angle β, the breast angle β of the second tooth 13 coinciding with the breast angle β of the first tooth 12.

Das Beispiel in Figur 2 zeigt damit erste und zweite Zähne 12 und 13, die sich in der Länge der Kardierfläche 18 und 18' unterscheiden. Die Kardierfläche 18' der zweiten Zähne 13 kann so klein ausgebildet sein, dass diese lediglich durch ein Abschleifen der Garnitur gebildet wird, indem auf einem zuvor spitz ausgebildeten zweiten Zahn 13 durch den Schleifprozess die Kardierfläche 18' erst gebildet wird.The example in FIG. 2 shows thus first and second teeth 12 and 13, which differ in the length of the carding 18 and 18 '. The carding surface 18 'of the second teeth 13 may be formed so small that it is formed only by a grinding of the set by the carding 18' is formed on a previously pointed second tooth 13 by the grinding process.

Figur 3 zeigt in einer Querschnittsansicht den Sägezahndraht 10, wobei die Zahnhöhe Z, die Schulterhöhe S und die Einschlagtiefe E dargestellt sind. Der Querschnittsverlauf erfolgt zwischen zwei Zähnen, sodass ein erster Zahn 12 in der Rückansicht gezeigt ist. FIG. 3 shows in a cross-sectional view of the sawtooth wire 10, wherein the tooth height Z, the shoulder height S and the Einschlagtiefe E are shown. The cross-sectional profile is between two teeth, so that a first tooth 12 is shown in the rear view.

Figur 4 zeigt schließlich eine Ausgestaltung des zweiten Zahnes 13, wobei die Zahnspitze 19 gebildet wird durch das Zusammenlaufen des Zahnrückens 16 mit der Zahnbrust 17. Erst bei einem Überschliff des gezeigten zweiten Zahnes 13 kann sich die Kardierfläche 18' bilden, wie durch eine gestrichelte Linie angedeutet. FIG. 4 Finally, shows an embodiment of the second tooth 13, wherein the tooth tip 19 is formed by the convergence of the tooth back 16 with the tooth face 17. Only when a cross-section of the second tooth 13 shown, the carding 18 'can form, as indicated by a dashed line.
