Definitions
- the invention relates to a feed comb arrangement for a combing machine comprising an intermittently driven feed roller pair arranged upstream of the feed comb arrangement in the transport direction of the fiber fleece to be combed, and a take-off arrangement arranged downstream of the feed comb arrangement, in particular in the form of take-off rollers.
- the food comb arrangement is formed by a flat food comb, which is equipped with a plurality of needles, the function of which is to synchronously transport the nonwoven fabric to be combed in the transport direction to the combing roller and to the tongs arrangement in accordance with the cycle of the combing games.
- Another task of the food comb is to compress and retain the fibers outside the transport phase when the take-off rollers pull the combed fibers out of the nonwoven fabric. Accordingly, fibers attached to the comb are detached from the fibers to be extracted.
- the movement sequence within a comb play is such that the feed rollers transport the nonwoven fabric over a certain distance in the direction of the combing cylinder and the take-off rollers. This make-up usually takes place at the moment when the combed fibers are pulled out of the nonwoven fabric held back by the comb. The comb is closed at this moment and the needles of the comb penetrate the nonwoven fabric. After the end of the feed, ie the transport movement through the feed rollers, the feed comb lifts out of the nonwoven fabric and moves back the distance that corresponds to the transport path through feed rollers.
- Conventional food combs are realized in such a way that the needles in the form of pin strips are introduced into a base plate, each pin strip comprising a plurality of needles arranged next to one another.
- the conventional food combs designed in this way have a considerable disadvantage in that, in addition to their transport and holding function, they also act as a combing element and cleaning element with respect to the nonwoven fabric, so that ever larger parts of burdock and straw parts accumulate on the needles of the food comb. These accumulations grow and are then drawn off in a compressed form, and because of their size they are often transported under the downstream fixed comb and accordingly remain as an impurity in the combed nonwoven.
- Another significant mechanical disadvantage of known combs is that they have to go through four movement phases in different directions within a comb play. These movement phases include an approximately circular-arc movement to emerge from the nonwoven fabric, a backward linear movement to initiate a new feed phase, a further circular movement to pierce the nonwoven fabric and then again a linear movement to carry out the transport. Such jerky movements at about 200 combs per minute result in a combing machine of the type in question being associated with considerable unrest.
- the object of the invention is to create a food comb arrangement which avoids the disadvantages of conventional food combs, in particular the accumulation of contaminants, and enables reliable transport and holding performance with a high level of smoothness.
- the feed comb arrangement comprises a plurality of needle bars rotating on a closed path, the orbit being designed such that the needles of the pinstripes engage in the nonwoven fabric during part of the circulation route and the nonwoven fabric is synchronized with the comb play sequence due to an intermittent Hold the drive in a first phase and transport it in a second phase.
- the comb arrangement according to the invention which is designed in the manner of a comb head, comprises a housing, curved tracks being formed on the inside of the lateral housing cheeks. Two inner curved tracks are used to transport the needle bars, whereas two outer tracks can be used to give the needle bars, which are preferably provided with one-sided cranks, the desired angular position of the needles.
- Such an arrangement is known to the person skilled in the art as a continuously driven device from so-called drafting systems (cf. DE-OS 25 48 315), the drive of the needle bars in previously known drafting systems either via a chain or via a linear drive (cf. EP-PS 0 184 671) can take place.
- drafting systems cf. DE-OS 25 48 315
- EP-PS 0 184 671 a linear drive
- the main difference between a feed comb arrangement according to the invention and previously known drafting arrangements lies in addition to the different purpose and location, especially in that the comb arrangement according to the invention is driven intermittently.
- drafting devices serve to prevent the fiber sliver from being torn off, which is stretched between two pairs of rollers, which for this purpose is continuously operated at different speeds, e.g. with a speed ratio of 1: 8. Accordingly, known drafting systems do not have to perform a transport function and, alternately, do not have to perform a holding function.
- the needle bars which are used in the feed comb arrangement according to the invention are designed in such a way that on one side of the needle bar there is the already mentioned crank which specifies the angular position of the pinstrip.
- Bearings are provided on the two end sides of each needle bar, which engage in the guide curves for the orbital movement.
- the alternating distance between the needle bars is also set by the bearings of the needle bar.
- the needles or needle-like stamped parts of the needle bar are arranged on it in a rotationally fixed manner and extend over the central region in accordance with the width of the nonwoven fabric.
- the needle bars are driven, for example, by sprockets, which ensure that the needle bars perform a certain distance in the direction of the take-off rollers in the interval of the comb play, as determined by the feed rollers as the transport path.
- the drive mechanism is preferably implemented in such a way that a drive disk is driven synchronously with the feeder rollers, preferably derived directly from the intermittent movement.
- FIG. 1 shows a food comb 1 according to the prior art.
- a combing machine (not shown in detail), a nonwoven fabric 2 to be combed is fed in the transport direction (arrow 3) through a pair of feed rollers 4 to a tongs arrangement 5, with a protruding part of the fiber beard 2 being combed by a circular comb 6 when the tongs arrangement 5 is closed and the combed part is pulled off again via a pair of take-off rollers 7.
- the food comb 1 shown in FIG. 1 executes a movement cycle which, according to FIG. 1a, comprises a linear transport movement in order to carry out the feeding.
- the feed comb 1 is then lifted upward in an approximately circular arc-shaped movement in order to pierce the nonwoven fabric, as shown in FIG. 1b.
- a conventional food comb 1 comprises a flat, plate-like support body 9 and a plurality of rows of needles 10.
- FIGS. 3 and 4 a comb arrangement according to the invention is shown in FIGS. 3 and 4.
- This comprises two side cheeks 11, on the inside of which guide tracks 12 are provided for the circumferential movement of needle bars 13 which are laterally mounted in the guide tracks 12 and which are provided with a multiplicity of needles or sawtooth punched parts 14, only a few of these are indicated in FIG. 4.
- Not shown in the drawing are crank projections of the needle bars 13, which run along a separate guideway and ensure that the needles or the tips of the sawtooth punched parts 14 have a desired orientation in every phase of movement with respect to the central longitudinal axis of each needle bar 13.
- the design in this regard is not described further here because it is known per se from drafting systems.
- the guideways 12 in the side cheeks 11 are designed such that the needles or sawtooth tips 14 engage along a lower section in the nonwoven fabric 2 and accordingly can transport this in a movement phase and hold it in a subsequent holding phase, after which they emerge from the nonwoven fabric and be moved upwards.
- a rotating cleaning brush 18 is arranged, which combs out contamination from the needles or sawtooth tips 14 passing by, a suction hood 19, which is connected to a suction channel 20, ensures that the combed out contamination in the direction of the arrow 21 are suctioned off.

Abstract
Description
Die Erfindung richtet sich auf eine Speisekammanordnung für eine Kämm-Maschine umfassend ein der Speisekammanordnung in Transportrichtung des zu kämmenden Faservlieses vorgeordnetes, intermittierend angetriebenes Speisewalzenpaar und eine der Speisekammanordnung nachgeordnete Abzugsanordnung, insbesondere in Form von Abzugswalzen.The invention relates to a feed comb arrangement for a combing machine comprising an intermittently driven feed roller pair arranged upstream of the feed comb arrangement in the transport direction of the fiber fleece to be combed, and a take-off arrangement arranged downstream of the feed comb arrangement, in particular in the form of take-off rollers.
Herkömmlicherweise wird die Speisekammanordnung durch einen flachen, mit einer Vielzahl von Nadeln besetzten Speisekamm gebildet, dessen Aufgabe es ist, das zu kämmende Faservlies in Transportrichtung zu der Kämmwalze und zur Zangenanordnung entsprechend dem Takt der Kämmspiele hiermit synchronisiert zu transportieren.Conventionally, the food comb arrangement is formed by a flat food comb, which is equipped with a plurality of needles, the function of which is to synchronously transport the nonwoven fabric to be combed in the transport direction to the combing roller and to the tongs arrangement in accordance with the cycle of the combing games.
Eine weitere Aufgabe des Speisekamms besteht darin, außerhalb der Transportphase die Fasern zu verdichten und zurückzuhalten, wenn die Abzugswalzen die gekämmten Fasern aus dem Faservlies abziehen. Dementsprechend werden durch den Speisekamm anhängende Fasern von den herauszuziehenden Fasern gelöst.Another task of the food comb is to compress and retain the fibers outside the transport phase when the take-off rollers pull the combed fibers out of the nonwoven fabric. Accordingly, fibers attached to the comb are detached from the fibers to be extracted.
Innerhalb eines Kammspieles ist der Bewegungsablauf so, daß die Speisewalzen das Faservlies über eine bestimmte Strecke in Richtung des Kämmzylinders und der Abzugswalzen transportieren. Diese Nachspeisung erfolgt in der Regel in dem Moment, in dem die bereits gekämmten Fasern aus dem durch den Speisekamm zurückgehaltenen Faservlies ausgezogen werden. Der Speisekamm ist in diesem Augenblick geschlossen und die Nadeln des Speisekammes durchsetzen das Faservlies. Nach Beendigung der Speisung, d.h. der Transportbewegung durch die Speisewalzen, hebt sich der Speisekamm aus dem Faservlies und bewegt sich um diejenige Wegstrecke zurück, die dem Transportweg durch Speisewalzen entspricht.The movement sequence within a comb play is such that the feed rollers transport the nonwoven fabric over a certain distance in the direction of the combing cylinder and the take-off rollers. This make-up usually takes place at the moment when the combed fibers are pulled out of the nonwoven fabric held back by the comb. The comb is closed at this moment and the needles of the comb penetrate the nonwoven fabric. After the end of the feed, ie the transport movement through the feed rollers, the feed comb lifts out of the nonwoven fabric and moves back the distance that corresponds to the transport path through feed rollers.
Er sticht dann durch den Speisekammrost wieder in das Faservlies ein und führt eine erneute Transportbewegung für das Faservlies aus. Der Speisekamm bleibt solange geschlossen, bis die Abzugswalzen den gekämmten Faserbart ausgezogen haben. Es beginnt dann ein neues Kammspiel und der Speisekamm öffnet sich wieder und gibt den Faserbart zur Speisung der Speisekammwalzen frei.He then punctures the non-woven fabric through the food comb grate and carries out a new transport movement for the non-woven fabric. The feed comb remains closed until the take-off rollers have pulled out the combed fiber beard. A new comb game then begins and the comb opens again and releases the fiber beard for feeding the comb rollers.
Herkömmliche Speisekämme werden so realisiert, daß in eine Grundplatte die Nadeln in Form von Nadelstreifen eingebracht werden, wobei jeder Nadelstreifen eine Vielzahl nebeneinander angeordneter Nadeln umfaßt.Conventional food combs are realized in such a way that the needles in the form of pin strips are introduced into a base plate, each pin strip comprising a plurality of needles arranged next to one another.
Die so ausgestalteten herkömmlichen Speisekämme weisen einen erheblichen Nachteil insoweit auf, als sie hinsichtlich des Faservlieses neben ihrer Transport- und Haltefunktion auch als Kämmelement und Reinigungselement wirken, so daß sich immer wieder größere Teile von Kletten und Strohteilen an den Nadeln des Speisekamms ansammeln. Diese Ansammlungen wachsen und werden dann in verdichteter Form abgezogen, wobei sie wegen ihrer Größe häufig unter dem nachgeordneten Fixkamm hindurchtransportiert werden und dementsprechend als Verunreinigung im gekämmten Faservlies erhalten bleiben.The conventional food combs designed in this way have a considerable disadvantage in that, in addition to their transport and holding function, they also act as a combing element and cleaning element with respect to the nonwoven fabric, so that ever larger parts of burdock and straw parts accumulate on the needles of the food comb. These accumulations grow and are then drawn off in a compressed form, and because of their size they are often transported under the downstream fixed comb and accordingly remain as an impurity in the combed nonwoven.
Um dies zu vermeiden, kann man nur so vorgehen, daß die Kämm-Maschine nach bestimmten Betriebszeiten stillgesetzt wird, um den Speisekamm zu reinigen, was natürlich zu unerwünschten Produktionseinbußen führt.To avoid this, the only way to proceed is to stop the combing machine after certain operating times in order to clean the comb, which of course leads to undesirable production losses.
Ein weiterer erheblicher mechanischer Nachteil bekannter Speisekämme liegt darin, daß solche innerhalb eines Kammspieles vier Bewegungsphasen in unterschiedlicher Richtung durchlaufen müssen. Diese Bewegungsphasen umfassen eine etwa kreisbogenförmige Bewegung, um aus dem Faservlies auszutreten, eine rückwärts gerichtete lineare Bewegung, um eine neue Vorschubphase einleiten zu können, eine weitere kreisförmige Bewegung zum Einstechen in das Faservlies und dann wiederum eine lineare Bewegung, um den Transport durchzuführen. Derartige ruckartige Bewegungen bei ca. 200 Kammspielen pro Minute führen dazu, daß eine Kämm-Maschine der in Betracht stehenden Art mit einer erheblichen Unruhe behaftet ist.Another significant mechanical disadvantage of known combs is that they have to go through four movement phases in different directions within a comb play. These movement phases include an approximately circular-arc movement to emerge from the nonwoven fabric, a backward linear movement to initiate a new feed phase, a further circular movement to pierce the nonwoven fabric and then again a linear movement to carry out the transport. Such jerky movements at about 200 combs per minute result in a combing machine of the type in question being associated with considerable unrest.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Speisekammanordnung zu schaffen, welche die Nachteile herkömmlicher Speisekämme, insbesondere die Ansammlung von Verunreinigungen, vermeidet und bei hoher Laufruhe eine zuverlässige Transport- und Halteleistung ermöglicht.Proceeding from this, the object of the invention is to create a food comb arrangement which avoids the disadvantages of conventional food combs, in particular the accumulation of contaminants, and enables reliable transport and holding performance with a high level of smoothness.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Speisekammanordnung eine Mehrzahl auf einer geschlossenen Bahn umlaufender Nadelstäbe umfaßt, wobei die Umlaufbahn so ausgebildet ist, daß die Nadeln der Nadelstreifen in das Faservlies während eines Teils der Umlaufstrecke eingreifen und das Faservlies synchron zum Kammspielablauf aufgrund eines intermittierenden Antriebes in einer ersten Phase festhalten und in einer zweiten Phase transportieren.This object is achieved according to the invention in that the feed comb arrangement comprises a plurality of needle bars rotating on a closed path, the orbit being designed such that the needles of the pinstripes engage in the nonwoven fabric during part of the circulation route and the nonwoven fabric is synchronized with the comb play sequence due to an intermittent Hold the drive in a first phase and transport it in a second phase.
Die erfindungsgemäße Speisekammanordnung, welche nach Art eines Speisekammkopfes ausgebildet ist, umfaßt ein Gehäuse, wobei an der Innenseite der seitlichen Gehäusewangen Kurvenbahnen ausgebildet sind. Zwei innere Kurvenbahnen dienen zum Transport der Nadelstäbe wohingegen zwei äußere Bahnen dazu herangezogen werden können, um den Nadelstäben, die vorzugsweise mit einseitigen Kurbeln versehen sind, die gewünschte Winkelstellung der Nadeln zu geben.The comb arrangement according to the invention, which is designed in the manner of a comb head, comprises a housing, curved tracks being formed on the inside of the lateral housing cheeks. Two inner curved tracks are used to transport the needle bars, whereas two outer tracks can be used to give the needle bars, which are preferably provided with one-sided cranks, the desired angular position of the needles.
Alternativ ist es auch möglich, auf die inneren Bahnen der Stäbe zu verzichten und stattdessen die Lagerung der Nadelstäbe in speziellen Lagerteilen an je einer umlaufenden Kette vorzusehen, so daß die Ketten Transport und Lagerung der Nadelstäbe übernehmen. Ein derartiger Transportmechanismus ist beispielsweise in der US-PS 3 854 169 beschrieben.Alternatively, it is also possible to dispense with the inner tracks of the rods and instead to provide for the storage of the needle rods in special bearing parts on a rotating chain, so that the chains take over transport and storage of the needle rods. Such a transport mechanism is described, for example, in US Pat. No. 3,854,169.
Eine derartige Anordnung ist dem Fachmann als kontinuierlich angetriebene Einrichtung von sogenannten Streckwerken her bekannt (vgl. DE-OS 25 48 315), wobei der Antrieb der Nadelstäbe bei vorbekannten Streckwerken entweder über eine Kette oder über einen Linearantrieb (vgl. EP-PS 0 184 671) erfolgen kann. Der wesentliche Unterschied einer erfindungsgemäßen Speisekammanordnung zu vorbekannten Streckwerken liegt neben dem unterschiedlichen Einsatzzweck und Einsatzort vor allem darin, daß die erfindungsgemäße Speisekammanordnung intermittierend angetrieben wird.Such an arrangement is known to the person skilled in the art as a continuously driven device from so-called drafting systems (cf. DE-OS 25 48 315), the drive of the needle bars in previously known drafting systems either via a chain or via a linear drive (cf. EP-PS 0 184 671) can take place. The main difference between a feed comb arrangement according to the invention and previously known drafting arrangements lies in addition to the different purpose and location, especially in that the comb arrangement according to the invention is driven intermittently.
Ein weiterer Unterschied besteht darin, daß Streckwerke dazu dienen zu verhindern, daß das Faserband abreißt, welches zwischen zwei Walzenpaaren gestreckt wird, die zu diesem Zweck kontinuierlich mit unterschiedlicher Umlaufgeschwindigkeit, z.B. mit einem Drehzahlverhältnis von 1:8, laufen. Dementsprechend müssen bekannte Streckwerke gerade keine Transportfunktion und abwechselnd hierzu auch keine Haltefunktion wahrnehmen.Another difference is that drafting devices serve to prevent the fiber sliver from being torn off, which is stretched between two pairs of rollers, which for this purpose is continuously operated at different speeds, e.g. with a speed ratio of 1: 8. Accordingly, known drafting systems do not have to perform a transport function and, alternately, do not have to perform a holding function.
Die Nadelstäbe, welche in der erfindungsgemäße Speisekammanordnung verwendet werden, sind so ausgestaltet, daß sich an einer Seite des Nadelstabes die bereits erwähnte Kurbel befindet, welche die Winkelstellung des Nadelstreifens vorgibt. An den beiden Endseiten jedes Nadelstabes sind Lager vorgesehen, die in die Führungskurven für die Umlauf-Bewegung eingreifen. Durch die Lager des Nadelstabes wird auch der wechselweise Abstand der Nadelstäbe zueinander eingestellt. Die Nadeln bzw. nadelartigen Stanzteile des Nadelstabes sind auf diesem drehfest angeordnet und erstrecken sich über den Mittelbereich entsprechend der Breite des Faservlieses.The needle bars which are used in the feed comb arrangement according to the invention are designed in such a way that on one side of the needle bar there is the already mentioned crank which specifies the angular position of the pinstrip. Bearings are provided on the two end sides of each needle bar, which engage in the guide curves for the orbital movement. The alternating distance between the needle bars is also set by the bearings of the needle bar. The needles or needle-like stamped parts of the needle bar are arranged on it in a rotationally fixed manner and extend over the central region in accordance with the width of the nonwoven fabric.
Der Antrieb der Nadelstäbe erfolgt beispielsweise über Kettenräder, die dafür sorgen, daß die Nadelstäbe im Intervall des Kammspiels eines bestimmte, von den Speisewalzen als Transportstrecke vorgegebene Strecke in Richtung der Abzugswalzen durchführen. Der Antriebsmechanismus wird vorzugsweise so realisiert, daß eine Antriebsscheibe synchron zu den Speisekammwalzen, vorzugsweise direkt von der intermittierenden Bewegung abgeleitet, angetrieben wird.The needle bars are driven, for example, by sprockets, which ensure that the needle bars perform a certain distance in the direction of the take-off rollers in the interval of the comb play, as determined by the feed rollers as the transport path. The drive mechanism is preferably implemented in such a way that a drive disk is driven synchronously with the feeder rollers, preferably derived directly from the intermittent movement.
Dies bedeutet also mit anderen Worten, daß immer dann, wenn die Speisewalzen das Faservlies um eine bestimmten Betrag transportieren, die Nadelstäbe der Speisekammanordnung linear um eine entsprechende Strecke in Transportrichtung laufen. Da eine erfindungsgemäße Speisekammanordnung bzw. ein solcher Speisekammkopf stationär mit der Maschine verbunden ist, bewirken die Nadelreihen der Nadelstäbe wie bei herkömmlichen Speisekämmen eine Rückhaltekraft auf das Faservlies, wenn die gekämmten Fasern aus dem Faservlies durch die Abzugswalzen abgezogen werden.In other words, this means that whenever the feed rollers transport the nonwoven fabric by a certain amount, the needle bars of the feed comb arrangement run linearly for a corresponding distance in the transport direction. Since a comb arrangement according to the invention or such a comb head is stationary connected to the machine, the rows of needles of the needle bars, as in conventional combs, have a retaining force on the nonwoven fabric when the combed fibers are drawn off the nonwoven fabric by the take-off rollers.
Da die Nadelstäbe entsprechend dem Kammspiel der Maschine eine Rollbewegung und eine überlagerte lineare Transportbewegung ausführen, treten alle Nadelstreifen, welche im Eingriff mit dem Faservlies waren, danach nach oben aus dem Faservlies aus, werden angehoben und können durch eine Putzeinrichtung, welche durch eine Bürste oder durch eine Saugeinrichtung realisiert sein kann, gesäubert werden, bevor sie nach Umlenkung wieder in das Faservlies einstechen.Since the needle bars perform a rolling movement and a superimposed linear transport movement in accordance with the comb play of the machine, all the pin strips which were in engagement with the nonwoven material then emerge upward out of the nonwoven fabric, are lifted and can be cleaned by a cleaning device which is carried out by a brush or can be realized by a suction device, be cleaned before they stick back into the nonwoven fabric after deflection.
Hierdurch wird nach der Erfindung ein ganz wesentlicher Vorteil erreicht, weil die Nadelstäbe immer wieder gereinigt und von Unreinheiten befreit werden, die sie beim Transport des Faservlieses und beim Abzug aufgenommen haben. Darüber hinaus ist eine derartige umlaufende Bewegung maschinentechnisch erheblich vorteilhafter, weil eine umlaufende Bewegung mit abgerundeten Bahnabschnitten eine wesentlich bessere Laufruhe gewährleistet als einander anschließende Bewegungen, welche um jeweils etwa 90° versetzt sind.As a result, a very significant advantage is achieved according to the invention, because the needle bars are cleaned again and again and are freed of impurities that they picked up during the transport of the nonwoven fabric and during the take-off. In addition, such a circumferential movement is considerably more advantageous in terms of machine technology, because a circumferential movement with rounded path sections ensures much smoother running than successive movements which are offset by approximately 90 ° in each case.

In Fig. 1 ist ein Speisekamm 1 gemäß dem Stand der Technik dargestellt. In einer im einzelnen nicht dargestellten Kämm-Maschine wird ein zu kämmendes Faservlies 2 in Transportrichtung (Pfeil 3) durch ein Paar von Speisewalzen 4 einer Zangenanordnung 5 zugeführt, wobei bei geschlossener Zangenanordnung 5 ein überstehender Teil des Faserbartes 2 durch einen Kreiskamm 6 gekämmt wird und der gekämmte Teil über ein Paar von Abzugswalzen 7 wieder abgezogen wird. Der Aufbau einer derartigen Kämm-Maschine, in welcher auch eine erfindungsgemäße Speisekammanordnung eingesetzt werden kann, ergibt sich beispielsweise aus der Firmendruckschrift NSC Flachkämm-Maschine PB30 von n.schlumberger & cie.1 shows a food comb 1 according to the prior art. In a combing machine (not shown in detail), a
Der in Fig. 1 dargestellte Speisekamm 1 führt einen Bewegungszyklus aus, der gemäß Fig. 1a eine lineare Transportbewegung umfaßt, um die Speisung vorzunehmen. Anschließend wird der Speisekamm 1 in einer etwa kreisbogenförmigen Bewegung nach oben angehoben, um aus dem Faservlies auszustechen, wie dies in Fig. 1b dargestellt ist.The food comb 1 shown in FIG. 1 executes a movement cycle which, according to FIG. 1a, comprises a linear transport movement in order to carry out the feeding. The feed comb 1 is then lifted upward in an approximately circular arc-shaped movement in order to pierce the nonwoven fabric, as shown in FIG. 1b.
Hieran schließt sich eine in Fig. 1c dargestellte, nach rückwärts gerichtete lineare Bewegung an, um einen neuen Vorschub des Faserbartes 2 einleiten zu können, welcher wiederum eine kreisförmige Bewegung zum Einstechen in den Faserbart 2 folgt, wie dies in Fig. 1d dargestellt ist, wobei der Speisekamm 1 dann in den Speisekammrost 8 eingreift.This is followed by a backward linear movement shown in FIG. 1c in order to be able to initiate a new advance of the
