Description

Die Erfindung betrifft eine Vorrichtung zum Ablegen eines Faserbandes in einer Kanne mit einem fest an einem Maschinenrahmen montierten Drehkopfträger gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for depositing a sliver in a jug with a turret carrier fixedly mounted on a machine frame.

Eine solche Vorrichtung zum Ablegen eines Faserbandes ist aus der DE-OS 33 18 944 bekannt. Das von der Karde kommende Faserband wird oberhalb des Drehkopfes über eine dort angeordnete Rolle dem Drehkopf zugeführt, wobei das Faserband über einen mit Umfangsgeschwindigkeit des Drehkopfes umlaufenden Einlauftrichter zu den beiden Kalanderwalzen geführt wird. Dadurch wird das Faserband nicht nur in seiner eigenen Transportrichtung, sondern auch in Umfangsrichtung des Drehkopfes bewegt. Hiermit tritt nicht nur eine starke mechanische Beanspruchung des Faserbandes ein, sondern es kommt auch zu einer unerwünschten Entwicklung feiner Textilstäube.Such a device for depositing a sliver is known from DE-OS 33 18 944. The sliver coming from the card is fed above the rotary head to the rotary head via a roller arranged there, the sliver being fed to the two calender rolls via an inlet funnel rotating at the peripheral speed of the rotary head. As a result, the sliver is not only moved in its own transport direction, but also in the circumferential direction of the rotary head. This not only results in strong mechanical stress on the sliver, but also in the undesirable development of fine textile dusts.

Aus der französischen Offenlegungsschrift 2 325 589 ist eine Vorrichtung zum Ablegen eines Faserbandes der eingangs genannten Art bekannt, bei der der Antrieb der einen Kalanderwalze durch ein auf der gleichen Drehwelle sitzendes Zahnrad erfolgt, welches an einem nach unten weisenden Zahnkranz des Drehkopfträgers abläuft. Das von den Kalanderwalzen transportierte Faserband gelangt anschließend in ein längeres Rohr, an dessen unterem Ende die Ablage in der Kanne erfolgt. Nachteilig bei dieser Vorrichtung ist, daß der Transport des Faserbandes in dem den Kalanderwalzen nachgeschalteten Rohr zu einer hohen mechanischen Beanspruchung des Faserbandes führt. Außerdem können hier Unregelmäßigkeiten beim Faserbandtransport auftreten, so daß die Ablage des Faserbandes in der Kanne nicht unbedingt in der gewünschten sorgfältigen Art und Weise erfolgt. Außerdem bereitet es bei dieser bekannten Vorrichtung Schwierigkeiten, die einem Verschleiß unterliegenden Antriebsteile zu warten bzw. von Zeit zu Zeit deren Austausch vorzunehmen. Ein solcher Austausch ist dann erforderlich, wenn infolge zunehmender Abnutzung ein für den Fasertransport ungünstiges und daher unerwünschtes Spiel zwischen dem als Ritzel ausgebildeten Antriebsrad und dem Zahnkranz auftritt. Maßnahmen zur Beseitigung eines solchen, im Laufe der Zeit auftretenden Spiels sind bei dieser bekannten Vorrichtung nicht vorgesehen. Schließlich sind Verschmutzungen des Faserbandes durch Schmiermittel, welches zur Schmierung des Ritzelantriebs erforderlich ist, nicht auszuschließen.From the French laid-open specification 2 325 589 a device for depositing a sliver of the type mentioned is known, in which the drive of the calender roll is effected by a gearwheel seated on the same rotating shaft, which runs on a downward-facing ring gear of the turret carrier. The sliver transported by the calender rolls then passes into a longer tube, at the lower end of which the filing takes place in the can. A disadvantage of this device is that the transport of the sliver in the tube downstream of the calender rolls leads to high mechanical stress on the sliver. In addition, irregularities in the sliver transport can occur here, so that the sliver is not necessarily deposited in the jug in the desired careful manner. In addition, with this known device it is difficult to maintain the drive parts which are subject to wear or to replace them from time to time. Such an exchange is necessary if, due to increasing wear, an unfavorable and therefore undesirable play occurs for the fiber transport between the drive wheel designed as a pinion and the ring gear. Measures to eliminate such a game occurring over time are not provided in this known device. Finally, contamination of the fiber sliver by lubricants, which is necessary for lubricating the pinion drive, cannot be ruled out.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Ablegen eines Faserbandes in einer Kanne zu schaffen, welche eine schonende und staubfreie Führung des Faserbandes ermöglicht und an welcher Reinigungs- und Wartungsarbeiten leicht durchzuführen sind.The invention has for its object to provide a device for depositing a sliver in a can, which allows gentle and dust-free guidance of the sliver and on which cleaning and maintenance work are easy to perform.

Zur Lösung dieser Aufgabe wird eine Vorrichtung gemäß Anspruch 1 vorgeschlagen. Bei dieser Vorrichtung sind die Kalanderwalzen, auf die Mittelachse des Drehtellers bezogen, auf der gleichen Seite wie das als Reibrad ausgebildete Antriebsrad angeordnet und das Lager der mit dem Reibrad drehfest verbundenen Kalanderwalze ist an einer schwenkbar auf dem Drehteller angeordneten Halterung ausgebildet.A device according to claim 1 is proposed to achieve this object. In this device, the calender rolls are related to the central axis of the turntable, arranged on the same side as the drive wheel, which is designed as a friction wheel, and the bearing of the calender roll, which is connected in a rotationally fixed manner to the friction wheel, is formed on a holder which is pivotably arranged on the rotary plate.

Da die Kalanderwalzen, auf die Mittelachse des Drehtellers bezogen, auf der gleichen Seite wie das Antriebsrad angeordnet sind, ergibt sich eine sehr kompakte Bauweise, bei der die Lager nur gering beansprucht werden. Außerdem wird es möglich, die Kalanderwalzen knapp oberhalb des Drehtellers anzuordnen, so daß das Faserband nach Verlassen der Kalanderwalzen auf dem kürzestmöglichen Weg und ohne die Gefahr von Stauchungen im Rohr, ferner auch schonend und staubfrei in die Kanne gelangt.Since the calender rolls, based on the center axis of the turntable, are arranged on the same side as the drive wheel, the result is a very compact design in which the bearings are only subjected to low loads. In addition, it becomes possible to arrange the calender rolls just above the turntable so that the sliver, after leaving the calender rolls, gets into the can in the shortest possible way and without the risk of upsetting in the tube, and also gently and dust-free.

Da das Lager der mit dem Reibrad dreh fest verbundenen Kalanderwalze an einer schwenkbar auf dem Drehteller angeordneten Halterung ausgebildet ist, lassen sich durch Verschwenken der aus Antriebsrad und Kalanderwalzen zusammengesetzten Baueinheit dort leicht Reinigungs- und Wartungsarbeiten durchführen. Die Verschwenkbarkeit der Halterung stellt außerdem sicher, daß kein Spiel zwischen der Ringfläche des Drehkopfträgers und dem Antriebsrad auftritt. Zur Vermeidung eines derartigen Spiels ist es außerdem von Vorteil, daß das Antriebsrad als Reibrad ausgebildet ist und damit ein bei Formschluß der Teile mögliches Spiel von vornherein ausscheidet.Since the bearing of the calender roller, which is connected to the friction wheel in a rotationally fixed manner, is formed on a holder which is pivotably arranged on the turntable, cleaning and maintenance work can easily be carried out there by pivoting the assembly composed of the drive wheel and calender rollers. The pivotability of the bracket also ensures that there is no play between the ring surface of the turret carrier and the drive wheel. To avoid such a game, it is also advantageous that the drive wheel is designed as a friction wheel and thus eliminates a possible game when the parts are positively locked.

An der Halterung ein das Faserband zu dem Spalt zwischen den Kalanderwalzen führendes Rohr befestigt. Das Rohr führt zu einer zusätzlichen Verbesserung der Führung des Faserbandes und insbesondere zu einem ruhigeren Lauf des Faserbandes innerhalb des Drehkopfes. Da das Rohr unmittelbar an der Halterung befestigt ist, ergibt sich eine weitere Vereinfachung der Konstruktion sowie eine besonders gute Zugänglichkeit bei Reinigungs- und Wartungsarbeiten.Attached to the bracket is a tube leading the sliver to the gap between the calender rolls. The tube leads to an additional improvement in the guidance of the sliver and in particular to a smoother running of the sliver within the rotary head. Since the tube is attached directly to the bracket, there is a further simplification of the construction and a particularly good accessibility for cleaning and maintenance work.

Vorzugsweise verlaufen die Drehachsen der Kalanderwalzen unter einem Neigungswinkel zwischen 20° und 70° zur Horizontalen. Das Faserband kann dem Drehkopf dann auf dessen Drehachse zugeführt werden, so daß Schwenkbewegungen des Faserbandes ausschließlich auf den Bereich innerhalb des Drehkopfes beschränkt bleiben.The axes of rotation of the calender rolls preferably run at an angle of inclination between 20 ° and 70 ° to the horizontal. The sliver can then be fed to the rotary head on its axis of rotation, so that pivoting movements of the sliver remain restricted to the area within the rotary head.

Eine Weiterbildung der Vorrichtung ist dadurch gekennzeichnet, daß die Längsachse des Rohres rechtwinklig zu den Drehachsen der Kalanderwalzen ausläuft.A further development of the device is characterized in that the longitudinal axis of the tube ends at right angles to the axes of rotation of the calender rolls.

Bei einer Ausgestaltung der Vorrichtung ist das Rohr unmittelbar vor dem zwischen den Kalanderwalzen ausgebildeten Spalt mit einer Luftstrahldüse zum Einführen des Faserbandes versehen. Die Luftstrahldüse ergreift auf schonende Weise den Anfang des Faserbandes und führt diesen zum weiteren Transport zwischen die beiden Kalanderwalzen.In one embodiment of the device, the tube is provided with an air jet nozzle for introducing the sliver immediately before the gap formed between the calender rolls. The air jet nozzle gently grips the beginning of the sliver and guides it for further transport between the two calender rolls.

Bei einer bevorzugten Ausgestaltung ist zumindest ein Lager der mit dem Reibrad drehfest verbundenen Kalanderwalze zwischen dieser Kalanderwalze und dem Reibrad angeordnet. Dadurch ergibt sich eine mit nur geringen Querkräften arbeitende Lagerung, so daß einfache und preiswerte Lager eingesetzt werden können.In a preferred embodiment, at least one bearing of the calender roll connected in a rotationally fixed manner to the friction wheel is arranged between this calender roll and the friction wheel. This results in a bearing working with only low transverse forces, so that simple and inexpensive bearings can be used.

Um einen sicheren Reibschluß zwischen Reibrad und Ringfläche des Drehkopfträgers sicherzustellen, ist bei einer Ausgestaltung der Vorrichtung vorgesehen, daß sich die Halterung über einen federbelasteten Knickarm an dem Drehteller abstützt. Zur Federbelastung des Knickarms wird beispielsweise ein Tellerfederpaket eingesetzt. Jedoch ist ebenso eine Gasdruckfeder einsetzbar, deren Vorteil in einem konstanten Anpreßdruck des Reibrades besteht.In order to ensure a secure frictional connection between the friction wheel and the ring surface of the turret carrier, it is provided in one configuration of the device that the holder is supported on the turntable via a spring-loaded articulated arm. For example, a plate spring assembly is used to load the articulated arm. However, a gas pressure spring can also be used, the advantage of which is a constant contact pressure of the friction wheel.

Ferner wird vorgeschlagen, daß das Reibrad in abgeknickter Stellung des Knickarms von der Ringfläche abhebt. Auf diese Weise lassen sich nach Abknicken des Knickarms bequem Wartungs- und Reparaturarbeiten an den Kalanderwalzen, dem Reibrad, dem Lager oder der Luftstrahldüse durchführen.It is also proposed that the friction wheel lifts off the ring surface in the bent position of the articulated arm. In this way, maintenance and repair work on the calender rolls, the friction wheel, the bearing or the air jet nozzle can be carried out easily after the articulated arm has been bent.

Da bei der Vorrichtung das Faserband zentrisch dem Drehkopf zugeführt werden kann, wird ferner vorgeschlagen, daß der Durchmesser der Lagerung des Drehkopfes geringer ist als der Durchmesser des Drehtellers. Auf diese Weise kann für die Lagerung des Drehkopfes ein Wälzlager geringen Durchmessers verwendet werden, so daß sich ein ruhiger und leiser Lauf des Drehkopfes innerhalb des Drehkopfträgers ergibt.Since the sliver can be fed centrally to the rotary head in the device, it is further proposed that the diameter of the bearing of the rotary head is smaller than the diameter of the turntable. In this way, a rolling bearing of small diameter can be used for the storage of the turret, so that the turret runs smoothly and quietly within the turret carrier.

Um eine besonders kompakte Bauweise sowie eine gute Zugänglichkeit zu den bewegten Teilen zu erhalten, wird schließlich vorgeschlagen, daß das Reibrad auf der Oberseite der kegelförmig ausgebildeten Ringfläche aufliegt.In order to obtain a particularly compact design and good accessibility to the moving parts, it is finally proposed that the friction wheel rests on the top of the conical ring surface.

Weitere Einzelheiten und Vorteile des Gegenstandes der Erfindung ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnungen, in denen eine bevorzugte Ausführungsform der Vorrichtung dargestellt ist. In den Zeichnungen zeigen:

Further details and advantages of the subject matter of the invention will become apparent from the following description of the accompanying drawings, in which a preferred embodiment of the device is shown. The drawings show:

Fig. 2
in a detailed view of FIG. 1, a turret carrier with an inserted turret.

Fig. 1 zeigt in einer Seitenansicht eine Vorrichtung zum Ablegen eines Faserbandes 1, die einer nicht dargestellten Karde nachgeordnet ist. Die Vorrichtung verfügt über einen Maschinenrahmen 2 mit einer Grundplatte 3, einem Drehkopfträger 4 sowie einer den Drehkopfträger 4 mit der Grundplatte 3 verbindenden Säule 5. Der Antrieb der Vorrichtung erfolgt über ein Antriebsritzel 6 in dem Drehkopfträger 4, welches über einen ersten Antriebsweg eine in der Grundplatte 3 gelagerte Drehplatte 7 antreibt. Auf der Drehplatte 7 ist eine zylindrische Kanne 8 zur Aufnahme des abgelegten Faserbandes 1 abgestellt. Über einen weiteren Antriebsweg wird die Drehbewegung des Antriebsritzels 6 über einen Antriebsriemen 9 auf einen innerhalb des Drehkopfträgers 4 vertikal gelagerten Drehkopf 10 übertragen. Der Drehkopf 10 führt innerhalb des Drehkopfträgers 4 eine kontinuierliche Drehbewegung aus, wobei diese Drehbewegung der Drehbewegung der die Kanne 8 aufnehmenden Drehplatte 7 überlagert ist. Da der Drehkopf 10 exzentrisch zur Längsachse der Kanne 8 gelagert ist, führt diese überlagerte Drehbewegung zu einem Ablegen des Faserbandes 1 in fortlaufenden Schleifen in der Kanne 8. Das in der Kanne 8 bereits abgelegte Faserband 1 wird von unten mit einer durch eine Feder erzeugten Druckkraft beaufschlagt, so daß die oberste Lage des Faserbandes 1 stets unmittelbar an der Unterseite des Drehkopfträgers 4 bzw. des Drehkopfes 10 anliegt.Fig. 1 shows a side view of a device for depositing a sliver 1, the card, not shown is subordinate. The device has a machine frame 2 with a base plate 3, a turret carrier 4 and a column 5 connecting the turret carrier 4 to the base plate 3. The device is driven by a drive pinion 6 in the turret carrier 4, which via a first drive path one in the Base plate 3 drives rotating plate 7 drives. On the rotary plate 7, a cylindrical can 8 is placed to hold the sliver 1. The rotational movement of the drive pinion 6 is transmitted via a further drive path via a drive belt 9 to a rotary head 10 mounted vertically within the rotary head carrier 4. The rotary head 10 executes a continuous rotary movement within the rotary head carrier 4, this rotary movement being superimposed on the rotary movement of the rotary plate 7 receiving the can 8. Since the rotary head 10 is mounted eccentrically to the longitudinal axis of the can 8, this superimposed rotary movement leads to the sliver 1 being deposited in continuous loops in the can 8. The sliver 1 already deposited in the can 8 is pressed from below with a compressive force generated by a spring acted on, so that the uppermost layer of the sliver 1 always abuts directly on the underside of the rotary head carrier 4 or the rotary head 10.

In der Fig. 2 ist dargestellt, daß sich der Drehkopfträger 4 in erster Linie aus zwei feststehenden, horizontalen Platten 11,12 und einem Deckblech 13 zusammensetzt. In der oberen Platte 11 ist mittels eines Wälzlagers 14 der Drehkopf 10 gelagert. Der Drehkopf 10 setzt sich aus einem inneren Lagerring 15, einer darauf montierten, von dem Antriebsriemen 9 umschlungenen Riemenscheibe 16 und einem um die Mittelachse A drehbaren Drehteller 17 zusammen, wobei der Drehteller 17 über mehrere vertikale Streben 18 mit dem inneren Lagerring 15 verbunden ist. Die Unterseite von Drehteller 17 und der unteren Platte 12 des Drehkopfträgers 4 schließen in der gleichen Ebene ab und liegen unmittelbar auf der in Fig. 2 nicht dargestellten obersten Lage des Faserbandes auf.2 shows that the turret support 4 is composed primarily of two fixed, horizontal plates 11, 12 and a cover plate 13. The rotary head 10 is supported in the upper plate 11 by means of a roller bearing 14. The rotary head 10 is composed of an inner bearing ring 15, a belt pulley 16 mounted thereon and wrapped by the drive belt 9, and a turntable 17 rotatable about the central axis A, the turntable 17 being connected to the inner bearing ring 15 via a plurality of vertical struts 18 connected is. The underside of the turntable 17 and the lower plate 12 of the turret support 4 terminate in the same plane and lie directly on the uppermost layer of the sliver (not shown in FIG. 2).

Auf der Oberseite des Drehtellers 17 ist an einem Lagerbock 19 eine um ein Gelenk 20 schwenkbare Halterung 21 befestigt. Die Halterung 21 besteht aus einem L-förmigen Winkelstück, dessen kurzer Schenkel eine Lagerhülse 22 trägt. Innerhalb der Lagerhülse 22 ist über zwei kleine Wälzlager eine Achse drehbar gelagert, die auf ihrem einen Ende eine erste Kalanderwalze 23 und auf ihrem anderen Ende ein mit der ersten Kalanderwalze 23 drehfest verbundenes Reibrad 24 trägt. Lagerhülse 22, Kalanderwalze 23 sowie Reibrad 24 bilden eine kompakte Baueinheit und befinden sich auf der gleichen Seite, bezogen auf die Mittelachse A des Drehtellers 17. Infolge der kurzen Bauweise treten in der Lagerhülse 22 nur geringe Lagerkräfte auf. Die Kalanderwalzen 23 befinden sich nur knapp oberhalb der Oberseite der Kanne 8, so daß das Faserband bis zur Kanne nur eine kurze Strecke zurücklegen muß.On the top of the turntable 17, a bracket 21 which is pivotable about a joint 20 is fastened to a bearing block 19. The bracket 21 consists of an L-shaped angle piece, the short leg of which carries a bearing sleeve 22. Within the bearing sleeve 22, an axle is rotatably supported by two small roller bearings, which carries a first calender roll 23 on one end and a friction wheel 24 connected non-rotatably to the first calender roll 23 on its other end. Bearing sleeve 22, calender roller 23 and friction wheel 24 form a compact structural unit and are located on the same side, with respect to the central axis A of the turntable 17. As a result of the short construction, only small bearing forces occur in the bearing sleeve 22. The calender rolls 23 are located just above the top of the can 8, so that the sliver only has to travel a short distance to the can.

Das aus Polyurethan bestehende Reibrad 24 liegt reibschlüssig auf einer schräg nach oben weisen und zu dem Drehkopf 10 konzentrischen Ringfläche 25 des Drehkopfträgers 4 auf. Die Ringfläche 25 ist hierbei an einem konischen Ring 26 ausgebildet, der fest innerhalb des Drehkopfträgers 4 abgestützt ist.The friction wheel 24, which is made of polyurethane, lies on an annular surface 25 of the rotary head carrier 4 which is oriented obliquely upward and concentric with the rotary head 10. The annular surface 25 is in this case formed on a conical ring 26 which is firmly supported within the rotary head carrier 4.

In Fig. 2 nicht erkennbar ist eine hinter der ersten Kalanderwalze 23 angeordnete, zweite Kalanderwalze gleichen Aufbaus, die ebenso wie die erste Kalanderwalze 23 um das Gelenk 20 schwenkbar an der Halterung 21 befestigt ist. Zwischen den beiden Kalanderwalzen befindet sich ein in seiner Breite einstellbarer Spalt.Not visible in FIG. 2 is a second calender roller of the same structure, which is arranged behind the first calender roller 23 and, like the first calender roller 23, is fastened to the holder 21 so as to be pivotable about the joint 20. A width-adjustable gap is located between the two calender rolls.

Die in Fig. 2 eingetragenen Drehachsen 27 der ersten Kalanderwalze 23 sowie der zweiten Kalanderwalze lassen deutlich deren Neigung zur Horizontalen erkennen. Beim Ausführungsbeispiel beträgt der Neigungswinkel der Drehachsen 27 zur Horizontalen etwa 45°.The axes of rotation 27 of the first calender roll 23 and the second calender roll entered in FIG. 2 clearly show their inclination to the horizontal. In the exemplary embodiment, the angle of inclination of the axes of rotation 27 to the horizontal is approximately 45 °.

An der Halterung 21 ist außerdem ein Rohr 28 befestigt, dessen Achse mit dem zwischen den beiden Kalanderwalzen ausgebildeten Spalt fluchtet und in der Zeichnung in etwa senkrecht auf den Drehachsen 27 der Kalanderwalzen steht. Auch das Rohr 28 weist daher einen Neigungswinkel von etwa 45° auf, wobei die obere Öffnung des Rohrs 28 unmittelbar unterhalb eines in dem Deckblech 13 angeordneten Einlauftrichters 29 mündet. Hierbei befinden sich sowohl die obere Mündung des Rohrs 28 als auch der Einlauftrichter 29 genau auf der Drehachse des Drehkopfes 10.A tube 28 is also attached to the holder 21, the axis of which is aligned with the gap formed between the two calender rolls and is approximately perpendicular to the axes of rotation 27 of the calender rolls in the drawing. The tube 28 therefore also has an angle of inclination of approximately 45 °, the upper opening of the tube 28 opening directly below an inlet funnel 29 arranged in the cover plate 13. Here, both the upper mouth of the tube 28 and the inlet funnel 29 are located exactly on the axis of rotation of the rotary head 10.

Das Rohr 28 verjüngt sich an seinem unteren Ende knapp oberhalb der beiden Kalanderwalzen zu einer Düse 30. Die Düse 30 ist mit einer nicht näher dargestellten Luftstrahldüse versehen, die über eine Druckluftleitung 31 an eine Druckluftquelle angeschlossen ist.The tube 28 tapers at its lower end just above the two calender rolls to form a nozzle 30. The nozzle 30 is provided with an air jet nozzle, not shown, which is connected via a compressed air line 31 to a compressed air source.

In Fig. 2 ist ferner dargestellt, daß die Halterung 21 über einen an der Halterung 21 befestigten Winkel 32 mit einem Knickarm 33 gelenkig gekoppelt ist. Der Knickarm 33 kann von Hand in Richtung des Pfeils 34 abgeknickt werden, wodurch sich die wirksame Länge des sich andererseits an dem Drehteller 17 gelenkig abstützenden Knickarm 33 verkürzen läßt. Hierdurch kommt es zu einem Zurückschwenken der Halterung 21 mit der ersten Kalanderwalze 23 und dem Reibrad 24. Zugleich wird auch das an der Halterung 21 befestigte Rohr 28 bis in eine horizontale Lage zurückgeschwenkt. Über zwei gerändelte Kontermuttern 35 läßt sich eine Feineinstellung der Länge des Knickarms 33 vornehmen. Ein Tellerfederpaket 36 erzeugt eine Druckkraft innerhalb des Knickarms 33 und führt damit im Ergebnis zu einer künstlichen Druckkraft des kegelförmig ausgebildeten Reibrades 24 auf der eine entsprechende Kegelform aufweisenden Ringfläche 25.In Fig. 2 it is also shown that the bracket 21 is articulated to an articulated arm 33 via an angle 32 attached to the bracket 21. The articulated arm 33 can be bent by hand in the direction of the arrow 34, as a result of which the effective length of the articulated arm 33, which is articulated on the turntable 17, can be shortened. This causes the holder 21 to pivot back with the first calender roller 23 and the friction wheel 24. At the same time, the tube 28 fastened to the holder 21 is also pivoted back into a horizontal position. Via two knurled lock nuts 35 can be fine-tuned the length of the articulated arm 33. A plate spring assembly 36 generates a compressive force within the articulated arm 33 and thus results in an artificial compressive force of the conical friction wheel 24 on the ring surface 25 having a corresponding conical shape.

Beim Betrieb der Vorrichtung gelangt das in Fig. 2 nicht dargestellte Faserband über den Einlauftrichter 29 in das Rohr 28, an dessen unterem Ende der Anfang des Faserbandes von der Luftstrahldüse erfaßt und in den Spalt zwischen der ersten Kalanderwalze 23 und der zweiten Kalanderwalze eingeführt wird. Nach diesem Einführvorgang erfolgt der weitere Transport des Faserbandes mit Hilfe der beiden Kalanderwalzen. Hierbei ist nur die erste Kalanderwalze 23 unmittelbar über das auf der Ringfläche 25 ablaufende Reibrad 24 angetrieben, während die zweite, in Fig. 2 nicht dargestellte Kalanderwalze als Freilaufwalze ausgebildet ist und allein aufgrund der Reibung des Faserbandes mitläuft. Nach Durchlaufen des Spaltes zwischen den Kalanderwalzen gelangt das Faserband über eine Öffnung 37 im Drehteller 17 auf kurzem Wege in die Kanne und wird dort horizontal abgelegt.During operation of the device, the sliver, not shown in FIG. 2, passes through the inlet funnel 29 into the tube 28, at the lower end of which the beginning of the sliver is gripped by the air jet nozzle and introduced into the gap between the first calender roll 23 and the second calender roll. After this insertion process, the sliver is transported further using the two calender rolls. In this case, only the first calender roller 23 is driven directly via the friction wheel 24 running on the annular surface 25, while the second calender roller, not shown in FIG. 2, is designed as a free-running roller and rotates solely due to the friction of the sliver. After passing through the gap between the calender rolls, the sliver passes through an opening 37 in the turntable 17 in a short way into the can and is deposited there horizontally.
