Description

Gebiet der Erfindungfield of invention

Die Erfindung betrifft einen Schneidsatz für einen Haarschneider bei dem die Schneidkante wellenförmig ausgebildet ist.The invention relates to a blade set for a hair clipper, in which the cutting edge is designed in a wavy manner.

Stand der TechnikState of the art

Im Stand der Technik gibt es eine Vielzahl von Haarschneidern mit unterschiedlichen Klingensätzen. Beispielsweise offenbart die US 7841901 B2 einen Klingensatz für einen Haarschneider umfassend mindestens eine stationäre Klinge mit mehreren stationären Klingenzähnen und mindestens eine bewegliche Klinge mit mehreren beweglichen Klingenzähnen, die zum seitlichen Hin- und Herbewegen relativ zu der mindestens einen stationären Klinge zum Schneiden von Haaren konfiguriert ist. Die bewegliche Klinge weist einen Satz langer Zähne auf, die zum Schneiden von Haaren über eine Breite der beweglichen Klinge konfiguriert sind, und einen Satz kurzer Zähne, die zum Schneiden von Haaren über die Breite der beweglichen Klinge konfiguriert sind, wenn eine Vorschubgeschwindigkeit des Haarschneiders eine bestimmte Geschwindigkeit überschreitet.In the state of the art there is a large number of hair clippers with different sets of blades. For example, the US7841901B2 a blade assembly for a hair clipper comprising at least one stationary blade having a plurality of stationary blade teeth and at least one movable blade having a plurality of movable blade teeth configured for lateral reciprocation relative to the at least one stationary blade for cutting hair. The movable blade has a set of long teeth configured to cut hair across a width of the movable blade and a set of short teeth configured to cut hair across the width of the movable blade when a feed speed of the hair clipper is one exceeds a certain speed.

Die US 5, 933,964 offenbart einen Haarschneider zum Schneiden von Haarsträhnen umfassend einen Klingensatz, der eine stationäre Klinge mit mehreren stationären Klingenzähnen aufweist, die in einer Reihe angeordnet sind, so dass Haarsträhnen zwischen benachbarten stationären Zähnen eintreten, wenn sich der Klingensatz durch die Haarsträhnen bewegt. Die stationären Schaufelzähne haben abgewinkelte seitliche Schneidkanten und Spitzen, und die seitlichen Schneidkanten benachbarter Zähne bilden dort Wurzeln, wo sie sich schneiden. Eine bewegliche Klinge hat mehrere bewegliche Klingenzähne, die ebenfalls in einer Reihe angeordnet sind. Die beweglichen Klingenzähne ergänzen die stationären Klingenzähne und gehen über die stationären Klingenzähne, um einige der Haarsträhnen zu schneiden. Die beweglichen Blattzähne sind relativ kurz und haben vorzugsweise flache Spitzen. Die Zähne der beweglichen Klinge sind durch klingenartige Kantenflächen getrennt, die in Bewegungsrichtung der beweglichen Klinge ausgerichtet sind und in der Lage sind, einige der Haarsträhnen zu schneiden, die zwischen die stationären Klingenzähne eintreten. Die messerartigen Klingenkanten bilden eine erste Linie, die zwischen einer zweiten Linie, die durch die Wurzeln der stationären Klingenzähne gebildet wird, und einer dritten Linie liegt, die durch die Spitzen der stationären Klingenzähne gebildet wird.the U.S. 5,933,964 discloses a hair clipper for cutting strands of hair comprising a blade assembly having a stationary blade with a plurality of stationary blade teeth arranged in a row such that strands of hair enter between adjacent stationary teeth as the blade assembly moves through the strands of hair. The stationary bucket teeth have angled lateral cutting edges and tips, and the lateral cutting edges of adjacent teeth root where they intersect. A moveable blade has multiple moveable blade teeth, also arranged in a row. The moveable blade teeth complement the stationary blade teeth and go over the stationary blade teeth to cut some of the strands of hair. The moving blade teeth are relatively short and preferably have flat tips. The movable blade teeth are separated by blade-like edge surfaces which are aligned in the direction of movement of the movable blade and are capable of cutting some of the strands of hair that enter between the stationary blade teeth. The knife-like blade edges form a first line that lies between a second line formed by the roots of the stationary blade teeth and a third line formed by the tips of the stationary blade teeth.

Bei diesen Haarschneidern steht das Schneiden der Haare in der gleichen Länge im Vordergrund. Mit diesen Haarschneidern ist das Schneiden eines Übergangs daher schwierig, weil durch die gleich geschnittene Haarlänge kleine Schnittfehler am Übergang sofort auffallen.With these hair clippers, the focus is on cutting the hair in the same length. It is therefore difficult to cut a transition with these hair clippers, because small cutting errors at the transition are immediately noticeable due to the hair being cut to the same length.

Darstellung der ErfindungPresentation of the invention

Aufgabe der vorliegenden Erfindung ist es eine Klingenanordnung bereitzustellen, die das Schneiden von Übergängen vereinfacht, so dass auch nicht-professionelle Anwender einen schönen Übergang erstellen können.The object of the present invention is to provide a blade assembly that simplifies the cutting of transitions so that even non-professional users can create a beautiful transition.

Die Aufgabe wird gelöst durch eine Klingenanordnung nach Anspruch 1. Weitere, die Erfindung ausgestaltende Merkmale sind in den abhängigen Ansprüchen enthalten.The object is solved by a blade assembly according to claim 1. Further features embodying the invention are contained in the dependent claims.

Eine erfindungsgemäße Klingenanordnung für einen Haarschneider, umfasst einen Kamm mit einer vorderen Schneidkante, die aus Zahnelementen ausgebildet ist, eine Klinge mit einer vorderen Schneidkante, die aus Zahnelementen ausgebildet ist, wobei die Schneidkante am vorderen Ende zur unteren Schneidkante hin abfallend ausgebildet ist und wobei die obere Klinge relativ zur unteren Klinge bewegbar ausgebildet ist, eine Verbindungseinrichtung, die den Kamm und die Klinge miteinander verbindet, und ein Federelement, das den Kamm und die Klinge zueinander vorspannt, wobei die Schneidkante der Klinge in einer Wellenform ausgebildet ist, wobei die vordere Schneidkante der Klinge mindestens 3 unterschiedlich lange Zahnelemente aufweist und/oder die Vorderkanten der einzelnen Zahnelemente entsprechend der Wellenform gekurvt/gekrümmt ausgebildet sind. Durch die unterschiedlich langen Zahnelemente und durch gekrümmte Schneidkanten der Zahnelemente werden die Haare in leicht unterschiedlicher Länge geschnitten, was das Schnittbild in den Übergängen bei einer normalen Anwendung des Haarschneiders ohne besondere Übung stark verbessert.A blade arrangement for a hair clipper according to the invention comprises a comb with a front cutting edge which is formed from toothed elements, a blade with a front cutting edge which is formed from toothed elements, the cutting edge being formed at the front end sloping towards the lower cutting edge and the upper blade is designed to be movable relative to the lower blade, a connecting device which connects the comb and the blade to one another, and a spring element which biases the comb and the blade towards one another, the cutting edge of the blade being formed in a wave shape, the front cutting edge the blade has at least 3 tooth elements of different lengths and/or the front edges of the individual tooth elements are curved/bent according to the waveform. Due to the different lengths of toothed elements and the curved cutting edges of the toothed elements, the hair is cut in slightly different lengths, which greatly improves the cutting pattern in the transitions during normal use of the hair clipper without any particular practice.

Vorzugsweise erstreckt sich eine Welle von einem höchsten Punkt der Welle zum nächsten über mindestens 4 Zahnelemente, weiter bevorzugt über 5 oder 6 und/oder über höchstens 15 Zahnelemente, weiter bevorzugt über 13 oder 10. Die Höhe von Wellenspitze bis Wellengrund liegt insbesondere zwischen 1mm und 4mm, bevorzugt maximal 3 mm, weiter bevorzugt maximal 2mm. Mit Wellenspitze wird der am weitesten vorne liegende Punkt der Welle bezeichnet, mit Wellengrund der am weitesten hinten liegende Punkt.A shaft preferably extends from one highest point of the shaft to the next over at least 4 tooth elements, more preferably over 5 or 6 and/or over at most 15 tooth elements, more preferably over 13 or 10. The height from the wave tip to the wave bottom is in particular between 1 mm and 4 mm, preferably at most 3 mm, more preferably at most 2 mm. The crest is the point furthest in front of the wave, and the bottom is the point furthest behind.

Die Wellenform ist vorzugsweise gleichmäßig ausgebildet, wodurch ein gleichmäßigeres Schneiden der einzelnen unterschiedlichen Haarlängen erreicht werden kann.The wave shape is preferably formed uniformly, as a result of which a more uniform cutting of the individual different hair lengths can be achieved.

Die äußersten seitlichen Zahnelemente können als Wellenspitze ausgebildet sein. Dadurch wird eine einheitliche und insbesondere symmetrische Klingenanordnung geschaffen, die die Herstellung vereinfacht.The outermost lateral tooth elements can be designed as a wave tip. This creates a uniform and, in particular, symmetrical blade arrangement, which simplifies manufacture.

Insbesondere sind die weiter vorne liegenden Schneidkanten der Zahnelemente dünner ausgebildet, als die weiter hinten liegenden.In particular, the cutting edges of the toothed elements that are further to the front are thinner than those that are further to the rear.

Ferner kann die vordere Schneidkante der oberen Klinge mindestens 4 unterschiedlich lange Zahnelemente aufweisen, bevorzugt 5 oder 6, höchstens aber 10.Furthermore, the front cutting edge of the upper blade can have at least 4 tooth elements of different lengths, preferably 5 or 6, but at most 10.

Vorzugsweise sind die Zahnelemente der Länge nach in aufsteigender und absteigender Reihenfolge angeordnet. Dadurch wird das Schnittbild des Übergangs gleichmäßiger und schöner.Preferably, the tooth elements are arranged lengthwise in ascending and descending order. This will make the cut of the transition smoother and more beautiful.

In particular, the oscillation takes place in a lateral direction (see arrow B in figure 2 ). The transmission element 20 can be firmly connected to the blade 40, 50, 60, 70 with a click system

In Figur 2 ist die Klingenanordnung 10 in einem montierten Zustand zu sehen, in dem alle Einzelteile der Klingenanordnung verbaut sind. In Figur 1 und Figur 2 ist zwar die Ausführungsform der Klinge 40 aus Figur 4 zu sehen, dies ist jedoch nur beispielhaft zu verstehen und die beschriebene Klingenanordnung kann mit jeder beliebigen Klinge verwendet werden.In figure 2 the blade assembly 10 can be seen in an assembled state, in which all individual parts of the blade assembly are installed. In figure 1 and figure 2 Although the embodiment of the blade 40 is from figure 4 1, but this is to be understood as exemplary only and the blade assembly described can be used with any blade.

In Figur 3 ist der Kamm 30 dargestellt. Figur 3a ist eine Ansicht auf die Oberseite des Kamms 30, wenn die Klingenanordnung 10 an einem Handgriff des Haarschneiders montiert ist. Der Kamm 30 weist eine vordere Kante 34 auf, die mit Zahnelementen 36 ausgebildet ist. Ferner weist der Kamm zwei Bohrungen 38 auf, an denen die Verbindungseinrichtung mit den Befestigungsmitteln 13 befestigt wird. Die Zahnelemente 36 sind vorzugsweise sich verjüngend ausgebildet, wobei die untere Seite (siehe Fig. 3b), an der die Klinge 40, 50, 60, 70 anliegt, flach geformt ist, damit der Schnitt nicht beeinträchtigt wird. D.h., die Neigung 31 ist an der oberen Seite ausgebildet und kann insbesondere auch schon vor den Zahnelementen beginnen.In figure 3 the comb 30 is shown. Figure 3a 12 is a view of the top of the comb 30 when the blade assembly 10 is mounted on a clipper handle. The comb 30 has a leading edge 34 formed with toothed elements 36 . Furthermore, the comb has two bores 38 to which the connecting device is fastened with the fastening means 13 . Tooth elements 36 are preferably tapered, with the lower side (see Figure 3b ) on which the blade 40, 50, 60, 70 rests, is formed flat so that the cut is not impaired. That is, the incline 31 is formed on the upper side and can in particular also begin before the toothed elements.

Figur 3c ist eine Seitenansicht des Kamms 30. Die Bohrungen 38 sind in Vertiefungen 37 angeordnet. Ferner ist auch vor den Zahnelementen 36 eine Vertiefung 35 ausgebildet. In diese Vertiefungen werden die Klingen 40, 50, 60, 70 derart eingesetzt, so dass sie durch das Betätigungselement vor und zurück und durch den Antrieb seitlich bewegbar sind. Figure 3c 12 is a side view of comb 30. Bores 38 are located in indentations 37. FIG. Furthermore, a recess 35 is also formed in front of the toothed elements 36 . The blades 40, 50, 60, 70 are inserted into these depressions in such a way that they can be moved back and forth by the actuating element and laterally by the drive.

In den Figuren 4 bis 7 sind verschiedene Ausführungsformen von Klingenanordnungen dargestellt. Der generelle Aufbau der Klingen 40, 50, 60, 70 ist gleich, weswegen die folgende Beschreibung für alle Klingen 50, 60, 70 gilt. in den Figuren 4a, 5a, 6a und 7a ist jeweils eine isometrische Ansicht auf die Unterseite der Klingen 40, 50, 60, 70 gezeigt. Die Figuren 4b, 5b, 6b und 7b sind Ansichten auf die Oberseite der Klingen 40, 50, 60, 70, die an dem Kamm 30 anliegen, und die Figuren 4b, 5b, 6b und 7b sind Ansichten auf die Unterseite der Klingen 40, 50, 60, 70. In der Klinge 40, 50, 60, 70 ist eine Befestigungsaussparung 41, 51, 61, 71 zur Befestigung des Übertragungselements 20 vorgesehen. Auf beiden Seiten der Befestigungsaussparung 41, 51, 61, 71 sind die Löcher 42, 52, 62, 72 für das Federelement 16 ausgebildet.In the Figures 4 to 7 Various embodiments of blade assemblies are shown. The general structure of the blades 40, 50, 60, 70 is the same, which is why the following description applies to all blades 50, 60, 70. in the figures 4a , 5a , 6a and 7a An isometric view of the underside of blades 40, 50, 60, 70 is shown in each case. the figures 4b , 5b , 6b and 7b Fig. 12 are top views of blades 40, 50, 60, 70 abutting comb 30, and Figs figures 4b , 5b , 6b and 7b are views of the underside of the blades 40, 50, 60, 70. In the blade 40, 50, 60, 70, a mounting recess 41, 51, 61, 71 for mounting the transmission element 20 is provided. The holes 42, 52, 62, 72 for the spring element 16 are formed on both sides of the fastening recess 41, 51, 61, 71.

In Figur 4d ist eine Seitenansicht der Klinge 40 dargestellt. Von der Seite erkennt man, dass die Klinge 40 zwei Lagerfüße 43 aufweist, die im montierten Zustand in den Vertiefungen 35, 37 aufgenommen sind. Die Füße 43 und die Vertiefungen 35, 37 sind derart ausgestaltet, dass die Bewegung der Klinge 40 nach vorne/hinten durch das Betätigungselement 18 gewährleistet ist. Der Verbindungsteil 43, sozusagen die Brücke 43, verbindet die Füße der Klinge 40 miteinander. Figur 4e ist eine Rückansicht der Klinge 40 und 4f ist eine Frontansicht, in der die Schneiden der Zahnelemente 46 zu erkennen sind. Diese Ansichten sind in den in Figur 5, 6 und 7 gezeigten Ausführungsformen nicht gezeigt. Diese Klingen 50, 60, 70 sind aber entsprechend ausgebildet.In Figure 4d A side view of blade 40 is shown. From the side you can see that the blade 40 has two bearing feet 43 which, when mounted, are in the recesses 35, 37 are included. The feet 43 and the indentations 35, 37 are designed in such a way that the movement of the blade 40 forwards/backwards by the actuating element 18 is ensured. The connecting part 43, so to speak the bridge 43, connects the feet of the blade 40 to one another. Figure 4e 4f is a rear view of the blade 40, and 4f is a front view showing the cutting edges of the tooth members 46. FIG. These views are in the in figure 5 , 6 and 7 shown embodiments not shown. However, these blades 50, 60, 70 are designed accordingly.

Die Zahnelemente 46, 56, 66, 76 sind an der vorderen Kante 44, 54, 64, 74 der Klinge 40 ausgebildet. Die Zahnelemente 46, 56, 66, 76 sind in einer Wellenform ausgebildet. Das bedeutet, die Erstreckung nach vorne (oben in Figur 4b) der einzelnen Zahnelemente 46 ist an eine insbesondere gleichmäßige Wellenlinie angepasst. Dadurch weisen die Zahnelemente 46, 56, 66, 76 unterschiedliche Längen nach vorne auf, so dass zumindest 3 unterschiedliche lange Zahnelemente 46, 56, 66, 76 vorhanden sind (kurz, mittel, lang) und sich eine Welle (von einem längsten Zahnelement 46, 56, 66, 76 zum nächsten längsten Zahnelement 46, 56, 66, 76) erstreckt. Die außen liegenden Zahnelemente 46, 56, 66, 76 sind bevorzugt auch die größten Zahnelemente 46, 56, 66, 76, so dass die Wellenlinie immer an einem Maximum abschließt. Ferner muss nicht an jedem Maximum der Wellenlinie ein Zahnelement 46, 56, 66, 76 platziert sein. Die Zahnelemente 46, 56, 66, 76 weisen an ihrem vorderen Ende Schneidkanten 48, 58, 68, 78 auf, die auf der Unterseite (der Seite die weg vom kamm 30 gerichtet ist) geneigt ausgebildet ist. In Figur 4d ist dies von der Seite zu erkennen. Auch in den Draufsicht der Figuren 4c, 5c, 6c und 7c ist eine Neigung der Schneidkanten 48, 58, 68, 78 dargestellt. Die Wellenformen sind bevorzugt gleichmäßig (d.h. immer gleich wiederkehrend) und weiter bevorzugt auch symmetrisch zu einer senkrechten durch das Wellenmaximum ausgebildet.The tooth elements 46, 56, 66, 76 are formed on the leading edge 44, 54, 64, 74 of the blade 40. FIG. The tooth elements 46, 56, 66, 76 are formed in a wave shape. That means the extension forward (above in Figure 4b ) of the individual toothed elements 46 is adapted to a particularly uniform wavy line. As a result, the toothed elements 46, 56, 66, 76 have different lengths towards the front, so that there are at least 3 different long toothed elements 46, 56, 66, 76 (short, medium, long) and a shaft (from a longest toothed element 46 , 56, 66, 76 to the next longest tooth element 46, 56, 66, 76). The toothed elements 46, 56, 66, 76 lying on the outside are preferably also the largest toothed elements 46, 56, 66, 76, so that the wavy line always ends at a maximum. Furthermore, a toothed element 46, 56, 66, 76 does not have to be placed at each maximum of the wavy line. The tooth elements 46, 56, 66, 76 have at their front end cutting edges 48, 58, 68, 78 which are formed inclined on the underside (the side facing away from the comb 30). In Figure 4d this can be seen from the side. Also in the plan view of the figures 4c , 5c , 6c and 7c an inclination of the cutting edges 48, 58, 68, 78 is shown. The waveforms are preferably formed uniformly (ie always recurring in the same way) and more preferably also symmetrically to a vertical line through the wave maximum.

Bei der Ausführungsform in Figur 4 ist nicht nur der Verlauf der Zahnelemente 46 sondern auch die Geometrie der Schneidkanten 48 der einzelnen Zahnelemente 46 an diese Wellenlinie angepasst, wodurch diese Schneidkanten 48 entsprechend der Wellenlinie gekrümmt ausgebildet sind (siehe auch die Vergrößerung in den Figuren 1 und 2). In der Ausführungsform von Fig. 4 geht jede Welle über 3 oder 4 Zahnelemente 46 und hat somit eine "kurze Welle". Durch die Anpassung an die Wellenlinie gibt es mindestens 3 unterschiedlich lange Zahnelemente 46, die konkrete Ausgestaltung der Zahnelemente 46 kann jedoch zu einer größeren Vielfalt führen. Beispielsweise sind die Zahnelemente 46' und 46"gleich lang, aber die Krümmung ist unterschiedlich. In Figur 4g ist eine Wellenlinie dargestellt, die an die Schneidkanten 48 der Zahnelemente 46 angelegt ist. Es ist zu erkennen, wie die Schneidkanten 48 entsprechend der Wellenlinie ausgebildet sind. Hier ist die "kurze Welle" dargestellt, aber die Schneidkanten der nachfolgend beschriebenen "mittleren Welle" und der "langen Welle" werden mit entsprechenden Wellenlinien ausgebildet.In the embodiment in figure 4 not only the course of the toothed elements 46 but also the geometry of the cutting edges 48 of the individual toothed elements 46 is adapted to this wavy line, as a result of which these cutting edges 48 are curved in accordance with the wavy line (see also the enlargement in Figs figures 1 and 2 ). In the embodiment of 4 each shaft goes over 3 or 4 gear elements 46 and thus has a "short shaft". Due to the adaptation to the wavy line, there are at least 3 toothed elements 46 of different lengths, but the specific configuration of the toothed elements 46 can lead to a greater variety. For example, the tooth elements 46' and 46'' are of the same length, but the curvature is different Figure 4g a wavy line is shown applied to the cutting edges 48 of the toothed elements 46 . It can be seen how the cutting edges 48 are formed in accordance with the wavy line. Here the "short shaft" is shown, but the cutting edges of those described below "medium wave" and the "long wave" are formed with corresponding wavy lines.

In Figur 5 ist eine zweite Ausführungsform der Zahnelemente dargestellt. Grundsätzlich ist der Aufbau der Klinge 50 der gleiche wie in Figur 4, nur dass hier die Wellenform eine längere Welle aufweist, d.h. die eine Welle geht hier zwischen 5, 6 oder 7 Zahnelementen 56 und weist somit eine "mittlere Welle" auf. Auch in dieser Ausführungsform sind die Schneidkanten 58 entsprechend der Wellenlinie gekrümmt ausgebildet.In figure 5 a second embodiment of the toothed elements is shown. Basically, the structure of the blade 50 is the same as in figure 4 , except that here the wave form has a longer wave, ie one wave here goes between 5, 6 or 7 tooth elements 56 and thus has a "middle wave". In this embodiment, too, the cutting edges 58 are curved in accordance with the wavy line.

In Figur 6 ist eine dritte Ausführungsform der Zahnelemente dargestellt. Auch hier ist der Aufbau der Klinge 60 grundsätzlich der gleiche wie in der ersten Ausführungsform, die in Figur 4 dargestellt ist. Im Vergleich zur "mittleren Welle" aus Figur 5 weist die Wellenform hier eine noch längere Welle auf, d.h. die eine Welle umfasst hier 10, 11 oder noch mehr Zahnelemente 66. Diese Wellenform wird als "lange Welle" bezichnet. Auch in dieser Ausführungsform sind die Schneidkanten 58 entsprechend der Wellenlinie gekrümmt ausgebildet.In figure 6 a third embodiment of the toothed elements is shown. Here, too, the structure of the blade 60 is basically the same as in the first embodiment, which is shown in figure 4 is shown. Compared to the "medium wave" out figure 5 the wave form here has an even longer wave, ie one wave here comprises 10, 11 or even more toothed elements 66. This wave form is referred to as a "long wave". In this embodiment, too, the cutting edges 58 are curved in accordance with the wavy line.

in Figur 7 ist eine weitere Ausführungsform dargestellt. Analog zu den vorhergehenden Ausführungsformen ist der Aufbau der Klinge 70 ebenfalls der gleiche wie in der ersten Ausführungsform, die in Figur 4 dargestellt ist. Hier weisen jedoch die Schneidkanten 78 der Zahnelemente 76 keine Krümmung auf, sondern die Wellenform wird durch den Mittelpunkt der Schneidkanten 78 gelegt. Es gibt daher unterschiedlich lang ausgebildete Zahnelemente 76 mit einer Schneidkante die im Wesentlichen keine Krümmung aufweist, sondern gerade ausgebildet ist. Mit diesen Zahnelementen 76 wird dann eine Wellenlinie nachgebildet, wobei sich zwei benachbarte Wellen immer ein Maximum "teilen". Gezeigt ist eine bevorzugte Ausführungsform der Klinge 70, bei denen eine Welle aus jeweils 5 Zahnelementen besteht, D.h. die Wellenlinie beginnt mit einem langen Zahnelement 76', es folgt ein mittleres Zahnelement 76", ein kurzes Zahnelement 76'" und wieder ein mittleres Zahnelement 76". Das abschließende lange Zahnelement 76' ist gleichzeitig der Beginn der benachbarten Welle. Diese Ausführungsform kann auch auf längere Wellenformen angewendet werden, indem weitere Zahnelemente 76 mit unterschiedlicher Länge hinzugefügt werden (bspw. ein Zahnelement das länger als das mittlere Zahnelement 76" ist, aber kürzer als das lange Zahnelement 76').in figure 7 another embodiment is shown. Analogously to the previous embodiments, the structure of the blade 70 is also the same as in the first embodiment, which is shown in FIG figure 4 is shown. Here, however, the cutting edges 78 of the toothed elements 76 do not have any curvature, but rather the waveform is placed through the center point of the cutting edges 78 . There are therefore tooth elements 76 of different lengths with a cutting edge which essentially has no curvature but is straight. A wavy line is then simulated with these toothed elements 76, with two adjacent waves always “sharing” a maximum. A preferred embodiment of the blade 70 is shown, in which a shaft consists of 5 toothed elements, i.e. the wavy line begins with a long toothed element 76', followed by a middle toothed element 76", a short toothed element 76'" and again a middle toothed element 76 ". The final long sprocket 76' is also the start of the adjacent wave. This embodiment can also be applied to longer waveforms by adding further sprockets 76 of different lengths (e.g. a sprocket longer than the middle sprocket 76", but shorter than the long tooth element 76').
