Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Herstellung eines gesponnenen Fadens aus einem Faserverband welcher mindestens einen separat zugeführten endlosen Faden zu einem Core-Garn umspinnt, umfassend einen Faserführungskanal mit einer Faserführungsfläche zur Führung der Fasern des Faserverbands und eine Führungsvorrichtung zur Führung des Endlosfadens in eine Einlassmündung eines Garnführungskanals, weiter umfassend eine Fluideinrichtung zur Erzeugung einer Wirbelströmung um die Einlassmündung des Garnführungskanals. Eine Vorrichtung zur Herstellung eines Core-Garns ist aus DE 198 04 341 bekannt. Es handelt sich dabei um eine Ringspinnvorrichtung, mit welcher mindesten ein endloser Faden dem gestreckten Faserband zugeführt und zusammen zu einem Garn versponnen wird. Es ist jedoch nicht bekannt, ein Core-Garn durch Fluidführung herzustellen. Eine Vorrichtung zur Herstellung eines Garns aus Stapelfasern mittels Fluidführung ist deshalb Aufgabe der Erfindung.
Eine Vorrichtung, in welcher die Fasern für die Einbindung der vorderen Faserenden durch den hinteren Teil der Fasern in einer Faserführung geführt sind und mittels welcher die Fasern derart vom erzeugten Luftwirbel erfasst werden können, dass ein gleichmässiges und festes Garn erzeugt werden kann, ist in US 5,528,895 beschrieben. Zur Führung der Fasern ist ein zum Garnführungskanal zentrisch angeordneter Dorn vorgesehen, um welchen die zugelieferten Fasern spiralförmig in Richtung zum Garnführungskanal verlaufen, um versponnen zu werden. Diese zentrale Einrichtung verhindert das Einbringen eines Endlosfadens oder mehrerer solcher, der oder die zwingend durch das Zentrum des Garnführungskanals verlaufen müssen.
Die Aufgabe wird im Wesentlichen dadurch gelöst, dass eine Faserführungsfläche zu einer Spindel mit einem Garnführungskanal hin weist, über und durch welche die Fasern in einer im Wesentlichen flach nebeneinander liegenden Formation gegen die Einlassmündung des Garnführungskanals geführt werden und das Faserführungselement mit der Faserführungsfläche zusätzlich eine in ein Faser- und Fadenführungsmittel eingelassene Führung für den mindestens einen Endlosfaden aufweist, sodass dieser mindestens eine Endlosfaden von den Fasern an der Spindel umsponnen werden kann.The invention relates to an apparatus and a method for producing a spun yarn from a fiber structure which spun at least one separately fed endless thread to a core yarn, comprising a fiber guide channel with a fiber guide surface for guiding the fibers of the fiber assembly and a guide device for guiding the continuous filament in an inlet mouth of a yarn guide channel, further comprising fluid means for generating a swirling flow around the inlet mouth of the yarn guide channel. A device for producing a core yarn is out DE 198 04 341 known. It is a ring spinning device, with which at least one endless thread is fed to the stretched sliver and spun together to form a yarn. However, it is not known to make a core yarn by fluid conduction. An apparatus for producing a yarn of staple fibers by means of fluid guidance is therefore an object of the invention.
A device in which the fibers for the integration of the front fiber ends through the rear part of the fibers are guided in a fiber guide and by means of which the fibers can be detected by the produced air swirl so that a uniform and strong yarn can be produced is in US 5,528,895 described. For guiding the fibers, a mandrel arranged centrally to the yarn guide mandrel is provided, around which the supplied fibers extend spirally in the direction of the yarn guide channel in order to be spun. This central device prevents the introduction of an endless thread or several such, which must necessarily pass through the center of the Garnführungskanals.
The object is essentially achieved in that a fiber guide surface to a spindle with a Garnführungskanal points, and through which the fibers are guided in a substantially flat adjacent formation against the inlet mouth of Garnführungskanals and the fiber guide element with the fiber guide surface additionally in a fiber and thread guiding means embedded guide for the at least one endless thread, so that this at least one continuous filament can be wound by the fibers on the spindle.

Figur 1a -c zeigt ein Gehäuse 1 mit den Gehäuseteilen 1a und 1b mit einem darin eingebauten Düsenblock 2, welcher Strahldüsen 3 enthält, mittels welchen eine vorgenannte Wirbelströmung erzeugt wird, sowie ein sogenanntes Faser- und Fadenführungsmittel 4, hier mit einer Förderfläche zur Förderung der Fasern F gezeichnet, mit einer darin eingelassenen Führung 5 für einen über eine Umlenkrolle 9 ab einer Spule S abziehbaren Endlosfaden C, z. B. ein Endlosfilament, ein Stapelfasergarn, ein Mono- oder Multifilament, zur Herstellung eines Core-Garns.
Die Strahldüsen 3 erzeugen die Wirbelströmung für den Drall durch welchen die über das Fasenführungsmittel 4 zugelieferten Fasern F in einem Drehsinn um die Stirnseite 6a der sogenannten Spindel 6 gedreht und in einen Garnführungskanal 7 der Spindel 6 hineingeführt werden. Die Fasern F werden in einem Faserführungskanal 13 auf der vorgenannten Förderfläche des Faser- und Fadenführungsmittels 4 aufgrund einer eingesaugten Luft gegen die Stirnseite 6a der Spindel 6 gefördert. Die eingesaugte Luft erfolgt aufgrund einer Injektorwirkung der Strahldüsen 3, welche derart vorgesehen sind, dass einerseits der genannte Luftwirbel erzeugt, aber andererseits auch Luft durch den Faserführungskanal 13 gesaugt wird. Diese Luft entweicht einem Konusteil 6b der Spindel 6 entlang durch einen Entlüftungshohlraum 8 in einen Luftauslass 10. Die Druckluft für die Strahldüsen 3 wird mittels eines Druckluftverteilraums 11 den Strahldüsen gleichmässig zugeführt.
Weiter unten wird darauf eingegangen, wie der Endlosfaden C in die Vorrichtung eingelegt werden kann. Die Führung 5 für den Endlosfaden C ist so ausgerichtet, dass sie zentrisch bzw. dass der geführte Endlosfaden C zentrisch in die Einlassmündung 6c der Spindel 6 eingeführt wird. FIG. 1a c shows a housing 1 with the housing parts 1a and 1b with a built therein nozzle block 2, which contains jet nozzles 3, by means of which an aforementioned vortex flow is generated, and a so-called fiber and thread guide means 4, here with a conveying surface for conveying the fibers F drawn, with a recessed therein guide 5 for a via a guide roller 9 from a coil S removable endless thread C, z. As an endless filament, a staple fiber yarn, a monofilament or multifilament, for the production of a core yarn.
The jet nozzles 3 generate the swirling flow for the swirl through which the fibers F supplied via the chamfering guide means 4 are rotated in a direction of rotation about the end face 6a of the so-called spindle 6 and into a yarn guide channel 7 of the spindle 6 be brought into it. The fibers F are conveyed in a fiber guide channel 13 on the aforementioned conveying surface of the fiber and yarn guide means 4 due to a sucked air against the end face 6a of the spindle 6. The sucked air takes place due to an injector effect of the jet nozzles 3, which are provided in such a way that on the one hand generates said vortex, but on the other hand also air is sucked through the fiber guide channel 13. This air escapes a cone portion 6b of the spindle 6 along through a venting cavity 8 in an air outlet 10. The compressed air for the jet nozzles 3 is supplied by means of a Druckluftverteilraums 11 the jet nozzles uniformly.
Below is discussed how the endless thread C can be inserted into the device. The guide 5 for the endless thread C is oriented so that it is centric or that the guided endless thread C is inserted centrally into the inlet opening 6c of the spindle 6.

Das Faser- und Fadenführungsmittel 4 ist vorzugsweise so gestaltet, dass die Faserführungsfläche 28 horizontal zu liegen kommt, wie in Figur 1a gezeichnet, oder aber das Faser- und Fadenführungsmittel 4 ist gegen die Stirnseite 6a der Spindel hin, z. B. an allen, oder nur an einigen Seiten, verjüngend geformt wie in Figur 1b . Das weist den Vorteil auf, dass die Fasern F bereits sehr zentral zur Stirnseite 6a gerichtet zur Einlassmündung 6c gelangen. Die in das Faser- und Fadenführungsmittel 4 eingelassene Führung 5 kann in beiden Fällen eine Nut zur Aufnahme des Endlosfadens C oder eine durchgehende Bohrung durch das Faser- und Fadenführungsmittel 4 sein, durch welche der Endlosfaden C hindurchgeführt wird. Anstatt das Faser- und Fadenführungsmittel 4 stark verjüngend zu formen, kann als weitere Möglichkeit ein rohrähnliches Element 5c, z. B. ein mit einer durchgehenden Öffnung versehenes Röhrchen im Faser- und Fadenführungsmittel 4 vorgesehen sein ( Figur 1c ), welches vorzugsweise näher an der Einlassmündung 6c liegt, und durch welches der Endlosfaden C zentral zur Einlassmündung 6c geführt wird. Falls das rohrähnliche Element 5c nur einen Teil der Führung 5 ist, so kann die restliche Führung 5 im Fadenführungsmittel 4 als Nut oder Bohrung gestaltet sein. Ist das Faser- und Fadenführungsmittel 4 zur Stirnseite 6a der Spindel 6 hin verjüngend gestaltet bzw. mit einem rohrähnlichen Element 5c versehen, so sind die Fasern F bereits am Ende des Faser- und Fadenführungsmittel 4 bzw. dem rohrähnlichen Elements 5c schon sehr zentral zum Garnführungskanal 7 hin gerichtet.The fiber and thread guide means 4 is preferably designed so that the fiber guide surface 28 comes to lie horizontally, as in FIG. 1a drawn, or the fiber and thread guide means 4 is against the end face 6a of the spindle out, z. B. at all, or only on some sides, tapered as in FIG. 1b , This has the advantage that the fibers F are already very centrally directed to the end 6a directed to the inlet port 6c. The guide 5 embedded in the fiber and thread guiding means 4 can in both cases be a groove for receiving the endless thread C or a through hole through the fiber and thread guiding means 4, through which the endless thread C is passed. Instead of forming the fiber and thread guide means 4 strongly tapered, as a further possibility, a tube-like element 5c, z. B. provided with a through-opening tube in the fiber and thread guide means 4 ( Figure 1c ), which is preferably closer to the inlet mouth 6c, and through which the endless thread C is guided centrally to the inlet mouth 6c. If the tube-like element 5c is only part of the guide 5, the rest of the guide 5 in the thread guide means 4 can be designed as a groove or bore. Is the fiber and thread guide means 4 tapered towards the end 6a of the spindle 6 or provided with a tube-like element 5c, the fibers F are already at the end of Fiber and thread guide means 4 and the tube-like element 5c already very centrally directed to the yarn guide channel 7 out.

In den Figuren 2, 2a und 2c erkennt man eine Faserabgabekante 29, welche sehr nahe an einer Einlassmündung 35 eines Garnführungskanals 45 liegt, welcher innerhalb einer sogenannten Spindel 32 angeordnet ist. Vorteilhafterweise ist die Faserabgabekante 29 mit einem vorgegebenen Abstand A zwischen derselben und der Einlassmündung 35, sowie einem vorgegebenen Abstand B zwischen einer die Kante beinhaltenden gedachten Ebene E parallel zu einer Mittellinie 47 des Garnführungskanals 45 und dieser genannten Mittellinie 47 angeordnet.
Dabei entspricht der Abstand A je nach Faserart und mittlerer Faserlänge und entsprechenden Versuchsresultaten einem Bereich von 0,1 bis 1,0 mm. Der Abstand B hängt von einem Durchmesser G der Einlassmündung 35 ab und liegt, je nach Versuchsresultaten, innerhalb eines Bereichs von 10 bis 30 % des genannten Durchmessers G.In the Figures 2, 2a and 2c one recognizes a fiber delivery edge 29, which lies very close to an inlet mouth 35 of a yarn guide channel 45, which is arranged within a so-called spindle 32. Advantageously, the fiber discharge edge 29 is arranged at a predetermined distance A between the same and the inlet mouth 35, and a predetermined distance B between an imaginary plane E containing the edge parallel to a center line 47 of the yarn guide channel 45 and said center line 47.
The distance A corresponds to a range of 0.1 to 1.0 mm, depending on the type of fiber and average fiber length and corresponding test results. The distance B depends on a diameter G of the inlet orifice 35 and, depending on the results of the test, lies within a range of 10 to 30% of the said diameter G.

Im Weiteren weist die Faserabgabekante 29 eine Länge D.1 (Fig. 2a) auf, welche in einem Verhältnis von 1:5 zum Durchmesser G des Garnführungskanals 45 steht und von einer Stirnfläche 30 eines Faserförderelements 27 (gemäss Figur 1a-c das Faser- und Fadenführungsmittel 4) und einer Faserführungsfläche 28 des Elements 27 gebildet wird. Dabei liegt die Stirnfläche 30, mit einer Höhe O, innerhalb des Bereichs des Durchmessers G und weist einen empirisch ermittelten Abstand H zwischen der Ebene E und der gegenüberliegenden Innenwand 48 des Garnführungskanals 45 auf. Wird das Faser- und Fadenführungsmittel 4 wie in Figur 1b zur Stirnseite 6a der Spindel 6 hin verjüngend gestaltet, oder wie in Figur 1c mit einem rohrähnlichen Element 5c versehen, müssen sämtliche Abstände ebenfalls entsprechend empirisch ermittelt werden.Furthermore, the fiber delivery edge 29 has a length D.1 (FIG. Fig. 2a ), which is in a ratio of 1: 5 to the diameter G of Garnführungskanals 45 and from an end face 30 of a fiber conveying element 27 (according Figure 1a-c the fiber and thread guide means 4) and a fiber guide surface 28 of the element 27 is formed. In this case, the end face 30, with a height O, lies within the range of the diameter G and has an empirically determined distance H between the plane E and the opposite inner wall 48 of the yarn guide channel 45. Will the fiber and thread guiding means 4 as in FIG. 1b designed to taper towards the end face 6a of the spindle 6, or as in Figure 1c provided with a tube-like element 5c, all distances must also be determined accordingly empirically.

Das Faserförderelement 27 weist ferner eine Führung 5.1 (eine Nut, Fig. 2b) bzw. 5.2 (eine Bohrung, Fig. 2b.1) zur Führung des Endlosfadens C auf und ist in einem im Düsenblock 20 aufgenommenen Tragelement 37 geführt und bildet mit diesem Tragelement einen Faserführungskanal 26 bildenden Freiraum und weist am Eingang eine Faseraufnahmekante 31 auf, um welche die Fasern geführt werden, die von einer Faserförderwalze 39 zugefördert werden. Diese Fasern werden von der Faserförderwalze 39 mittels eines Saugluftstroms von der Förderwalze abgehoben und durch den Faserführungskanal 26 gefördert. Der Saugluftstrom entsteht durch einen in Strahldüsen 21 mit einer Blasrichtung 38 erzeugten Luftstrom, aufgrund einer Injektorwirkung.The fiber conveying element 27 furthermore has a guide 5.1 (a groove, Fig. 2b ) or 5.2 (a hole, Fig. 2b.1 ) for guiding the endless thread C and is guided in a recorded in the nozzle block 20 support member 37 and forms with this support member a fiber guide channel 26 forming space and has at the entrance a fiber receiving edge 31, around which the fibers are guided, which are conveyed by a fiber feed roller 39. These fibers are lifted from the conveyor roller 39 by the suction conveying air by means of a suction air flow and conveyed through the fiber guide channel 26. The suction air flow is produced by a jet of air generated in jet nozzles 21 with a blowing direction 38 due to an injector effect.

Diese Strahldüsen sind, wie in den Figuren 2 und 2b dargestellt, in einem Düsenblock 20 einerseits mit einem Winkel β, um die vorgenannte Injektorwirkung zu erzeugen und andererseits mit einem Winkel α schräggestellt, um einen Luftwirbel zu erzeugen, welcher mit einer Drehrichtung 24 an einem Konus 36 des Faserförderelements 27 entlang und um Spindelfrontflächen 34 herumdreht, um wie anschliessend erwähnt, ein Garn im Garnführungskanal 45 der Spindel 32 zu bilden. Die Faserführungsfläche 28 weist in Faserführungsrichtung eine Vertiefung 5.1 zur Führung des Endlosfadens C auf (Fig. 2a von oben, Fig. 2b im Schnitt). In diese Vertiefung 5.1 wird der Endlosfaden C eingelegt und anschliessend von den Fasern F umsponnen.These jet nozzles are, as in the Figures 2 and 2b shown in a nozzle block 20 on the one hand with an angle β to produce the aforementioned injector effect and on the other hand inclined at an angle α to produce a vortex of air which rotates with a direction of rotation 24 on a cone 36 of the fiber conveying element 27 and around spindle front surfaces 34 to form a yarn in the yarn guide channel 45 of the spindle 32 as mentioned below. The fiber guide surface 28 has a recess 5.1 in the fiber guiding direction for guiding the endless thread C ( Fig. 2a from above, Fig. 2b on average). In this recess 5.1 of the endless thread C is inserted and then wound by the fibers F.

Der von den Düsen 21 in einer Wirbelkammer 22 erzeugte Luftstrom entweicht einem Spindelkonus 33 entlang durch einen sich um eine sogenannte Spindel 32 (Nr. 6 in Fig. 1a-c) gebildeten Entlüftungskanal 23 in die Atmosphäre oder in eine Saugeinrichtung. Zur Bildung eines Core-Garns 46 werden die von der Faserförderwalze 39 angelieferten Fasern F mittels des genannten Saugluftstroms im Faserführungskanal 26, wie erwähnt, von der Faserförderwalze 39 abgehoben und auf der Faserführungsfläche 28 in einer Förderrichtung 25 zusammen mit dem Endlosfaden C gegen die Faserabgabekante 29 geführt. Von dieser Abgabekante werden die einen Enden der Fasern durch die Spindeleinlassmündung 35 in den Garnführungskanal 45 geführt, während die anderen, zweiten Enden 49 dieser Fasern umklappen, sobald diese zweiten Enden frei und vom sich drehenden Luftstrom erfasst werden. Beim Weiterfördern der Fasern im Garnführungskanal 45 um den Endlosfaden C herum entsteht auf diese Weise ein Core-Garn 46, welches einen Garncharakter ähnlich dem Ringgarn aufweist.The air flow generated by the nozzles 21 in a swirl chamber 22 escapes a spindle cone 33 along a so-called spindle 32 (No. 6 in FIG Fig. 1a-c ) formed vent passage 23 into the atmosphere or in a suction device. To form a core yarn 46, the fibers F delivered by the fiber conveying roller 39 are lifted off from the fiber conveying roller 39 by means of said suction air flow in the fiber guiding channel 26 and onto the fiber guiding surface 28 in a conveying direction 25 together with the endless thread C against the fiber discharge edge 29 guided. From this discharge edge, the one ends of the fibers are guided through the spindle inlet mouth 35 into the yarn guide channel 45, while the other, second ends 49 of these fibers fold over as soon as these second ends are exposed and caught by the rotating air flow. When further conveying the fibers in the yarn guide channel 45 to the endless thread C around in this way creates a core yarn 46 which has a yarn character similar to the ring yarn.

Dieser Vorgang ist ähnlich auch in den Figuren 2.1 bis 2b.1 dargestellt. Darin ist ersichtlich, dass die mit der Faserförderwalze 39 angelieferten Fasern F zusammen mit dem hier durch eine Bohrung 5.2 im Faserförderelement 27 geführten Endlosfaden C (Fig. 2.1 von der Seite; Fig. 2b.1 im Schnitt) in der Förderrichtung 25 auf der Faserführungsfläche 28 gegen die Faserabgabekante 29 geführt werden, und zwar wie aus Figur 2a.1 gezeigt, mittels eines konvergierenden Faserstroms, welcher zunehmend gegen die Einlassmündung 35 eingeschnürt wird. Diese Einschnürung erfolgt deshalb, weil die vorderen Enden in Laufrichtung der Fasern gesehen, welche bereits im gedrehten Garn 46 eingebunden sind, die Tendenz haben, in Richtung Einschnürung zu wandern, so dass weiter hinten liegende zweite Enden von Fasern ebenfalls in Richtung Einschnürung verschoben werden. Dies geschieht jedoch nur solange, bis die zweiten Enden 49 der Fasern F vom genannten Luftwirbel erfasst, um die Spindelfrontfläche 34 herumgedreht und mit der Fadenabzugsgeschwindigkeit in die Einlassmündung 35 gezogen werden und dabei den für die Garnbildung notwendigen Drall erhalten.This process is similar also in the Figures 2.1 to 2b.1 shown. It can be seen that the fibers F supplied with the fiber conveying roller 39 are conveyed together with the endless thread C (shown here through a bore 5.2 in the fiber conveying element 27). Fig. 2.1 of the page; Fig. 2b.1 in section) are guided in the conveying direction 25 on the fiber guide surface 28 against the fiber discharge edge 29, namely as from Figure 2a.1 shown by means of a converging fiber stream, which is increasingly constricted against the inlet mouth 35. This necking occurs because the front ends seen in the direction of travel of the fibers already incorporated in the twisted yarn 46 have a tendency to migrate in the direction of constriction, so that further downstream second ends of fibers are also displaced in the direction of constriction. However, this happens only until the second ends 49 of the fibers F are detected by said air vortex, are turned around the spindle front surface 34 and drawn into the inlet mouth 35 at the yarn withdrawal speed, thereby obtaining the twist necessary for yarn formation.

In der Figur 2a.1 ist die Breite d.1 mittels strichpunktierten Linien erweitert dargestellt. Dies einerseits um zu zeigen, dass diese Breite erweitert werden kann, andererseits um darzustellen, dass diese erweiterte Breite d.1 unter Umständen die in Figur 2a gezeigte Wirbelkammer 22 verkleinert, wenn nicht sogar störend verändert, indem sich der Wirbelstrom darin nicht mehr so entwickeln kann, dass die Faserenden 49 mit der gewünschten Energie vom Wirbelstrom erfasst werden können. Dies muss mit empirischen Versuchen ermittelt werden.In the Figure 2a.1 the width d.1 is shown enlarged by means of dotted lines. On the one hand to show that this width can be extended, on the other hand to show that this extended width d.1 may be the one in FIG. 2a shown vortex chamber 22 reduced, if not disturbing changed by the eddy current can not develop in it so that the fiber ends 49 can be detected with the desired energy from the eddy current. This must be determined by empirical tests.

Die vorerwähnte Garnbildung geschieht nach Beginn eines Anspinnvorgangs irgend welcher entsprechender Art, beispielsweise in welchem ein Garnende eines bereits bestehenden Garns zurück durch den Garnführungskanal 45 in den Bereich der Spindeleinlassmündung 35 so weit geführt wird, dass Fasern dieses Garnendes vom sich bereits drehenden Luftstrom so weit geöffnet werden, dass neu durch den Faserführungskanal 26 zugeführte Enden von Fasern von diesem sich drehenden Faserverband erfasst werden können. Durch erneutes Abziehen des eingeführten Garnendes werden die nachfolgenden Teile der neu zugelieferten Fasern, die sich bereits um die im Mündungsteil des Garnführungskanals befindlichen Enden herumwinden können, mitgezogen, so dass in der Folge das vorerwähnte Garn mit einem im Wesentlichen vorgegebenen Ansatz erneut gesponnen werden kann. Zu Beginn des Anspinnvorgangs kann mit der vorgeschlagenen Vorrichtung der Endlosfaden C von einem Ende der Spinnvorrichtung her durch das Faden- und Faserführungsmittel (4) und durch den Garnführungskanal (46) eingeschossen werden, so dass er am anderen Ende gefasst und z. B. an einen Wickel angebracht werden kann. Weiter unten werden anhand von schematischen Darstellungen Vorrichtungsvorschläge beschrieben, mit denen der Einschiess- und der Einlegevorgang wesentlich vereinfacht werden kann.The aforementioned yarn formation happens after the beginning of a piecing process of any corresponding type, for example, in which a yarn end of an already existing yarn is guided back through the yarn guide channel 45 in the region of the spindle inlet port 35 so far that fibers of this yarn end so far from the already rotating air flow will be that newly fed through the fiber guide channel 26 ends of fibers can be detected by this rotating fiber strand. By re-stripping the inserted yarn end are the subsequent parts of the newly supplied fibers, which already able to wind around the ends located in the mouth part of the yarn guide channel, pulled along so that, as a consequence, the aforesaid yarn can be spun again with a substantially predetermined formulation. At the beginning of the piecing process, with the proposed device, the endless thread C can be injected from one end of the spinning device through the thread and fiber guiding means (4) and through the yarn guide channel (46), so that it is grasped at the other end and z. B. can be attached to a winding. Below are described on the basis of schematic representations device proposals with which the Einschiess- and inserting process can be significantly simplified.

Die Faserführungsfläche 28 bzw. die Faserabgabekante 29 kann unterschiedlich geformt sein, z. B. konkav, konvex oder gewellt. Diese Formen dienen der unterschiedlichen Faserführung auf der Faserführungsfläche 28 und sind je nach Faserart und Faserlänge empirisch zu ermitteln. Dabei hat sich ergeben, dass sich konkav für sog. "schlüpfrige Fasern" und konvex für sog. "klebrige" Fasern eignet. Dabei versteht man unter "schlüpfrigen" Fasern solche, welche eine schwache gegenseitige Adhäsion und unter "klebrigen" Fasern solche, welche eine gegenseitig stärkere Adhäsion aufweisen.The fiber guide surface 28 and the fiber discharge edge 29 may be formed differently, for. B. concave, convex or wavy. These shapes are used for different fiber guidance on the fiber guide surface 28 and are to be determined empirically depending on the fiber type and fiber length. It has been found that concave is suitable for so-called "slippery fibers" and convex for so-called "sticky" fibers. By "slippery" fibers is meant those which have a weak mutual adhesion and "sticky" fibers which have mutually stronger adhesion.

Figur 3a und 3b zeigen einen Lösungsvorschlag zur Modifikation der oben gezeigten Vorrichtung (Figuren zu 2ff.) für das Einlegen des Endlosfadens C vor dem Anspinnen. Zu sehen ist ein Düsenblock 20 entsprechend den Figuren 2 bzw. 2.1. In Figur 3a ist ein Teil 20' des Düsenblocks 20 inklusive Tragelement 37 entlang der Linie M entsprechend der Figur 2b aufklappbar und kann so abgehoben werden, dass die Faserführungsfläche 28 und die darin eingebrachte Nut 5.1 frei zugänglich sind. Ein Endlosfaden C zur Herstellung eines Core-Garns kann mühelos eingelegt werden, ohne dass er durch die Nut 5.1 eingefädelt werden muss. Im Falle der Führung 5 in Form einer Bohrung 5.2 wird, wie in Figur 3b schematisch dargestellt, ein Teil des Faserführungselements 27' entlang der Linie M' entsprechend der Figur 2b.1 nach unten weggeklappt. So wird die Bohrung 5.2 freigelegt und der Endlosfaden C kann eingelegt werden. Im Falle eines ins Fadenführungsmittel 4 eingesetzten rohrähnlichen Elements 5c, welches kürzer als das Fadenführungsmittel 4 ist, wird entsprechend auf der verbleibenden Länge des Fadenführungsmittels 4 vorhandenen Nut 5.1 oder Bohrung 5.2 ein oberer bzw. unterer Teil des Düsenblocks 20 weggeklappt. Durch das rohrähnliche Element 5c muss ein Endlosfaden C entsprechend der gängigen Technik eingefädelt oder eingeschossen werden; die Strecke wird durch ein kurzes, kleiner als das Fadenführungsmittel 4, rohrähnliches Element jedoch verkürzt und in den beiden anderen Fällen fällt der Einschiessvorgang vollständig weg. FIG. 3a and 3b show a proposed solution for the modification of the device shown above (Figures 2ff.) For inserting the endless thread C before piecing. You can see a nozzle block 20 corresponding to the Figures 2 or 2.1. In FIG. 3a is a part 20 'of the nozzle block 20 including support member 37 along the line M according to the FIG. 2b hinged and can be lifted so that the fiber guide surface 28 and introduced therein groove 5.1 are freely accessible. An endless thread C for producing a core yarn can be easily inserted without having to be threaded through the groove 5.1. In the case of the guide 5 in the form of a bore 5.2 is, as in FIG. 3b schematically shown, a part of the fiber guide element 27 'along the line M' according to the Figure 2b.1 folded down. Thus, the hole 5.2 is exposed and the endless thread C can be inserted. In the case of a pipe-like used in the thread guide means 4 Elements 5c, which is shorter than the thread guide means 4, corresponding to the remaining length of the thread guide means 4 existing groove 5.1 or bore 5.2, an upper or lower part of the nozzle block 20 is folded away. Through the tube-like element 5c, an endless thread C must be threaded or injected according to the usual technique; However, the distance is shortened by a short, smaller than the thread guide means 4, tube-like element and in the other two cases, the Einschiessvorgang completely eliminated.
