- the compacting device and the threading device are designed and arranged such that the calender rolls can be accommodated between them. These provide for the transport of the formed in the densification device sliver in the subsequent band channel, being provided directly after the calender rolls the threading device.
- a nearly closed web and tape guide from the compacting device or even from the output cylinder of the drafting system into the strip channel of the turntable results when the compacting device from one side and the threading device protrude from the other side into the respective gap formed by the calender rolls.
- the lateral deflection of the sliver during the insertion process in the direction of the nip line of the two calender rolls is prevented.
- the extremely short sliver path from the drafting system into the sliver channel as well as the widely available guidance of the sliver via the mentioned running path provides a very small susceptibility to interference, since the sliver has no opportunity to emerge in open areas.
- the compacting device comprises a fleece nozzle, which may be similar to known nonwoven nozzles for collecting the stretched, present in nonwoven form fiber material.
- the nonwoven nozzle preferably comprises a pivotable wall plate, which is held by magnets on the carrier, and pivots away from the carrier against the magnetic force in case of congestion in the nonwoven nozzle.

- the carrier is held by magnets on a drafting device holder.
- the carrier is then removable by appropriate exercise of force in a simple manner, on the other hand held securely in its operating position.
- the undesirably accumulated fiber material pushes the carrier out of its operating position.
- an electrical contact or the interruption of an electrical contact
- a sensor may be used here, which monitors the operating position of the carrier and advantageously also the pivotable wall plate located thereon.
- the carrier is held in each case a cylindrical bearing on both sides of the carrier by means of magnets.
- the magnets on the one hand are preferably designed to be adjustable, so that the other side of the carrier can fit tightly against the cylinder bearing there. In this way a sealless air supply can be guaranteed (see below).
- a further structural simplification results when a stripper for one of the calender rolls is arranged on the compacting device.
- the compression device advantageously has at least one Injektorbohrung which is connected to a first air supply line for compressed air.
- at least two injector bores are provided to provide the nonwoven with sufficient thrust for transport through the throat of the compactor.
- the one or more injector bores are preferably formed in an insert which can be inserted into the nonwoven nozzle.
- the compression device is formed in this embodiment essentially by the fleece nozzle and the fleece nozzle insert. A commonly existing in known machines band hopper between the fleece nozzle insert and the calender rolls can be omitted in this embodiment.

- two Injektorbohritch preferred to produce the desired spin in the band before filing in the spinning can.
- the first air supply line and / or the second air supply line particularly preferably run in the carrier, since this no space-intensive and disturbing in handling hoses in the control room are needed.
- hoses can further at a Tape accumulation at the fleece nozzle or in similar disturbances undesirably deposit fiber material on the hoses, which further complicates the handling. Also, care should be taken when inserting parts in the operating position on the hose routing.
- the first and the second air supply line are particularly preferably fed by a common supply feed provided on the carrier, since then only a single external air supply to the carrier must be present.
- no seal is used here at the compressed air transfer point of the feed supply.
- the carrier is instead located close to the corresponding compressed air transfer point, for example with the aid of the cylinder bearings mentioned above.
- the first and the second air supply line are formed by bores in the carrier, wherein furthermore preferably a manifold in the carrier from the feed supply leads to a branch from which the first and the second air supply line branch off.

Description
Die Erfindung betrifft eine Vorrichtung zur Anordnung nach den ausgangsseitigen Streckwerkswalzen eines Streckwerks.The invention relates to a device for the arrangement of the output-side drafting rollers of a drafting system.
Es ist bekannt, bei Spinnereivorbereitungsmaschinen mit einem Streckwerk im Anschluss an die Streckwerkswalzen eine Verdichtungseinrichtung vorzusehen, die das im Streckwerk ausgebreitete Fasermaterial zusammenführt. Bei einer Strecke liegt das Fasermaterial im Streckwerk als Vlies vor, das dann nach anschließender Verdichtung zu einem Faserband von einem Kalanderwalzenpaar in einen sich drehenden Bandkanal befördert wird, der das Faserband schlaufenförmig in eine Spinnkanne ablegt.It is known to provide a compaction device in spinning preparation machines with a drafting system following the drafting rollers, which unites the fiber material spread in the drafting system. In one stretch, the fiber material in the drafting system is present as a nonwoven, which is then conveyed to a sliver by a pair of calender rolls in a rotating band channel after subsequent compaction, which stores the sliver looped into a sliver can.
Es ist beispielsweise von der Strecke RSB-D 40 der Firma Rieter Ingolstadt Spinnereimaschinenbau AG bekannt, für das Verdichten eine Vliesdüse mit einer Vliesführungsdüse zu verwenden, denen ein Bandtrichter mit Injektorkanälen nachgeschaltet ist. Das aus dem Bandtrichter austretende Band wird von den Kalanderwalzen zu einem separaten Injektor transportiert, der das Band in den Bandkanal einfädelt.It is known, for example, from the line RSB-D 40 from Rieter Ingolstadt Spinnereimaschinenbau AG to use a fleece nozzle with a nonwoven guide nozzle for compacting, to which a belt hopper with injector channels is connected downstream. The belt leaving the belt hopper is transported by the calender rollers to a separate injector, which threads the belt into the belt channel.
Diese bekannte Anordnung hat sich sehr gut bewährt. Bei einer kompakteren Konstruktion des Streckwerks hingegen liegen die Bauteile enger zusammen, was die Handhabung und die Zugänglichkeit der einzelnen Bauteile in dem dem Streckwerk nachgeordneten Bereich betrifft.This known arrangement has proven very well. In a more compact design of the drafting system, however, the components are closer together, which relates to the handling and accessibility of the individual components in the downstream of the drafting area.

Es ist Aufgabe der vorliegenden Erfindung, eine Vorrichtung zwischen einem Streckwerk und einem Bandkanal zur Verfügung zu stellen, bei der die Handhabung und Zugänglichkeit erleichtert ist.It is an object of the present invention to provide a device between a drafting and a belt channel, in which the handling and accessibility is facilitated.
Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art durch die Merkmale des Anspruchs 1 gelöst.This object is achieved in a device of the type mentioned by the features of
Die Vorteile der Erfindung sind insbesondere darin zu sehen, dass durch den erfindungsgemäßen Träger eine kompakte Baueinheit erhalten wird, in dem die wichtigsten Vlies- und Bandführungselemente integriert bzw. an dem sie vorgesehen sind. Es ergibt sich somit ein extrem einfaches Handling. Der Träger weist außerdem den Vorteil auf, dass die Anzahl an Einzelbauteilen deutlich reduziert werden kann. Der Benutzer muss demnach nicht zwangsläufig mit Einzelteilen in dem kleinen Bauraum hantieren, sondern kann den Träger mit den daran angeordneten Bauteilen, insbesondere der Verdichtungseinrichtung und der Einfädeleinrichtung, aus seiner Betriebsposition entnehmen und als Ganzes wieder einsetzen. Hierzu muss lediglich die dem Streckwerk abgewandte Kalanderwalze weggeschwenkt oder auf andere Weise entfernt werden, um dann durch vorzugsweise einen einzigen Handgriff den Träger samt Verdichtungs- und Einfädeleinrichtung aus der Betriebsposition zu lösen und zu entfernen.The advantages of the invention are to be seen in particular in that a compact structural unit is obtained by the carrier according to the invention, in which the main fleece and tape guide elements integrated or on which they are provided. This results in an extremely easy handling. The carrier also has the advantage that the number of individual components can be significantly reduced. Accordingly, the user does not necessarily have to handle individual parts in the small construction space, but can remove the support with the components arranged thereon, in particular the compression device and the threading device, from its operating position and reinsert it as a whole. For this purpose, only the calender roll facing away from the drafting device has to be swung away or otherwise removed, in order then to detach and remove the carrier together with the compacting and threading device from the operating position by preferably a single handle.
Bevorzugt ist der Träger als umlaufender Rahmen ausgebildet. An einem oberen Rahmenteil ist dann die Verdichtungseinrichtung und an einem unteren Rahmenteil die Einfädeleinrichtung angeordnet. Die beiden Rahmenteile sind vorzugsweise durch seitliche Streben verbunden. Gemäß einer Alternative ist nur an einer Seite eine Strebe vorhanden. Diese Ausgestaltungen erleichtern die Handhabung und fördern die Kompaktheit der Konstruktion.Preferably, the carrier is designed as a peripheral frame. The compression device is then arranged on an upper frame part and the threading device is arranged on a lower frame part. The two frame parts are preferably connected by lateral struts. According to an alternative, only one side has a strut. These embodiments facilitate handling and promote the compactness of the construction.
Eine geschlossene Ausbildung des Rahmens fördert dessen Steifigkeit und somit die präzise Lagerung in seiner Betriebsposition.A closed design of the frame promotes its rigidity and thus the precise storage in its operating position.
Der Träger ist vorzugsweise durch eine im wesentlichen lineare Bewegung in seine Betriebsposition zwischen Streckwerk und Bandkanal bringbar und aus dieser wieder entfernbar. Der Träger wird hierbei bevorzugt an seinen beiden seitlichen Streben angefasst und von vorne in seine Betriebsposition geführt.The carrier is preferably brought by a substantially linear movement in its operating position between drafting and belt channel and removed from this again. The carrier is hereby preferably touched on its two lateral struts and guided from the front to its operating position.
Umständliche Bewegungen in mehreren Raumrichtungen erübrigen sich. Hierbei kann der Träger z.B. mit beiden Händen links und rechts von den Kalanderwalzen ergriffen und in Position gebracht werden. Alternativ kann der Träger auch mit nur einer Hand positioniert werden, was einer vereinfachten Handhabung noch weiter entgegenkommtCumbersome movements in several directions are unnecessary. Here, the carrier may be e.g. with both hands to the left and to the right of the calender rolls and be brought into position. Alternatively, the carrier can also be positioned with one hand, which even further accommodates simplified handling
Besonders bevorzugt sind die Verdichtungseinrichtung und/oder die Einfädeleinrichtung oder Teile von den vorgenannten Elementen einstückig am Träger angeformt, da ansonsten mechanische Verspannungen, nicht justierte Verbindungen oder Faseransammlungen an den Verbindungsstellen resultieren könnten.Particularly preferably, the compression device and / or the threading device or parts of the aforementioned elements are integrally formed on the support, otherwise mechanical stresses, unadjusted connections or fiber accumulations at the connection points could result.
Die Verdichtungseinrichtung und die Einfädeleinrichtung sind derart ausgebildet und angeordnet, dass zwischen ihnen die Kalanderwalzen Platz finden. Diese sorgen für den Transport des in der Verdichtungseinrichtung geformten Faserbandes in den nachfolgenden Bandkanal, wobei direkt nach den Kalanderwalzen die Einfädeleinrichtung vorgesehen ist.The compacting device and the threading device are designed and arranged such that the calender rolls can be accommodated between them. These provide for the transport of the formed in the densification device sliver in the subsequent band channel, being provided directly after the calender rolls the threading device.
Eine nahezu geschlossene Vlies- und Bandführung von der Verdichtungseinrichtung bzw. sogar vom Ausgangszylinder des Streckwerks bis in den Bandkanal des Drehtellers resultiert, wenn die Verdichtungseinrichtung von der einen Seite und die Einfädeleinrichtung von der anderen Seite in den jeweils von den Kalanderwalzen gebildeten Spalt hineinragen. Durch die von oben in den Kalanderwalzenspalt hineinreichende Verdichtungseinrichtung wird das seitliche Ausweichen des Faserbandes beim Einführvorgang in Richtung der Klemmlinie der beiden Kalanderwalzen verhindert. Außerdem verschafft der extrem kurze Faserbandweg vom Streckwerk in den Bandkanal sowie die überall vorhandene Führung des Faserbandes über den genannten Laufweg eine sehr kleine Störungsanfälligkeit, da das Faserband keine Gelegenheit hat, an offenen Stellen auszutreten.A nearly closed web and tape guide from the compacting device or even from the output cylinder of the drafting system into the strip channel of the turntable results when the compacting device from one side and the threading device protrude from the other side into the respective gap formed by the calender rolls. By reaching from above into the calender nip compression device, the lateral deflection of the sliver during the insertion process in the direction of the nip line of the two calender rolls is prevented. In addition, the extremely short sliver path from the drafting system into the sliver channel as well as the widely available guidance of the sliver via the mentioned running path provides a very small susceptibility to interference, since the sliver has no opportunity to emerge in open areas.
Vorzugsweise umfasst die Verdichtungseinrichtung eine Vliesdüse, die ähnlich bekannten Vliesdüsen zur Sammlung des verstreckten, in Vliesform vorliegenden Fasermaterials ausgebildet sein kann. Bei einer diesbezüglichen Ausführungsform umfasst die Vliesdüse vorzugsweise eine verschwenkbare Wandplatte, die durch Magneten am Träger gehalten ist, und bei Staubildung in der Vliesdüse gegen die Magnetkraft vom Träger wegschwenkt. Die verschwenkte Wandplatte kann hierbei das gestaute aber zunächst noch weitergeförderte Faservlies zielgerichtet aus dem Kalanderbereich ableiten. Zudem wird vorzugsweise mittels eines elektrischen Kontakts ein Abstellsignal an die Maschine gegeben. Durch ein Verschwenken vom Streckwerk weg und nach vorne hat eine Bedienperson dann leichten Zugriff auf die Vliesdüse, falls es hier zu Verstopfungen mit Fasermaterial kommen sollte.Preferably, the compacting device comprises a fleece nozzle, which may be similar to known nonwoven nozzles for collecting the stretched, present in nonwoven form fiber material. In a related embodiment, the nonwoven nozzle preferably comprises a pivotable wall plate, which is held by magnets on the carrier, and pivots away from the carrier against the magnetic force in case of congestion in the nonwoven nozzle. In this case, the tilted wall plate can purposely derive the jammed but initially further conveyed nonwoven from the calender area. In addition, a stop signal is preferably given to the machine by means of an electrical contact. By pivoting away from the drafting and forward an operator then easy access to the fleece nozzle, if it should come to blockages with fiber material.
Vorzugsweise ist der Träger an der verschwenkbaren Wandplatte mit den Händen bzw. mit einer Hand greifbar, so dass - ggf. zusätzlich zu einem Ergreifen an den oben genannten seitlichen Trägerstreben - auch hier die Handhabung insgesamt erleichtert ist.Preferably, the carrier is gripped on the pivotable wall plate with the hands or with one hand, so that - if necessary, in addition to a gripping on the above-mentioned lateral support struts - here, the handling is facilitated as a whole.
Es hat sich zudem als vorteilhaft erwiesen, dass der Träger durch Magnete an einem Streckwerkshalterung gehalten ist. Einerseits ist der Träger dann durch entsprechende Kraftausübung in einfacher Weise entfernbar, andererseits in seiner Betriebsposition sicher gehalten. Sollten sich Wickel an der Ausgangsoberwalze oder am Kalander bilden oder wäre eine Störung im Bereich der Vliesdüse gegeben, ist es mittels dieser Konstruktion möglich, dass das unerwünschtermaßen angesammelte Fasermaterial den Träger aus seiner Betriebsposition wegdrückt. Hierdurch kann dann ein elektrischer Kontakt (bzw. das Unterbrechen eines elektrischen Kontaktes) ein automatisches Abstellen der Spinnereivorbereitungsmaschine bewirken. Alternativ oder zusätzlich kann hierbei ein Sensor zum Einsatz kommen, der die Betriebsposition des Trägers und vorteilhafterweise auch der daran befindlichen verschwenkbaren Wandplatte überwacht.It has also proved to be advantageous that the carrier is held by magnets on a drafting device holder. On the one hand, the carrier is then removable by appropriate exercise of force in a simple manner, on the other hand held securely in its operating position. Should coils form on the output top roller or on the calender or if there is a disturbance in the area of the fleece nozzle, it is possible with this construction that the undesirably accumulated fiber material pushes the carrier out of its operating position. As a result, an electrical contact (or the interruption of an electrical contact) can then cause an automatic shutdown of the spinning preparation machine. Alternatively or additionally, a sensor may be used here, which monitors the operating position of the carrier and advantageously also the pivotable wall plate located thereon.
Gemäß einer Weiterbildung der Erfindung ist der Träger in jeweils einem Zylinderlager zu beiden Seiten des Trägers mit Hilfe von Magneten gehalten. Die Magneten auf der einen Seite sind vorzugsweise justierbar ausgebildet, damit die andere Seite des Trägers eng am dortigen Zylinderlager anliegen kann. Auf diese Weise kann eine dichtungslose Luftzuführung gewährleistet werden (s. unten).According to one embodiment of the invention, the carrier is held in each case a cylindrical bearing on both sides of the carrier by means of magnets. The magnets on the one hand are preferably designed to be adjustable, so that the other side of the carrier can fit tightly against the cylinder bearing there. In this way a sealless air supply can be guaranteed (see below).
Eine weitere konstruktive Vereinfachung ergibt sich, wenn an der Verdichtungseinrichtung ein Abstreifer für einer der Kalanderwalzen angeordnet ist.A further structural simplification results when a stripper for one of the calender rolls is arranged on the compacting device.
Die Verdichtungseinrichtung weist vorteilhafterweise mindestens eine Injektorbohrung auf, die mit einer ersten Luftzufuhrleitung für Druckluft verbunden ist. Vorteilhafterweise sind mindestens zwei Injektorbohrungen vorhanden, um dem Faservlies genügenden Schub zum Transport durch die Engstelle der Verdichtungseinrichtung zu verleihen.The compression device advantageously has at least one Injektorbohrung which is connected to a first air supply line for compressed air. Advantageously, at least two injector bores are provided to provide the nonwoven with sufficient thrust for transport through the throat of the compactor.
Der oder die Injektorbohrungen sind vorzugsweise in einem Einsatz ausgebildet, der in die Vliesdüse einsetzbar ist. Die Verdichtungseinrichtung ist bei dieser Ausgestaltung im wesentlichen durch die Vliesdüse und den Vliesdüseneinsatz gebildet. Ein bei bekannten Maschinen häufig vorhandener Bandtrichter zwischen dem Vliesdüseneinsatz und den Kalanderwalzen kann bei dieser Ausführung entfallen.The one or more injector bores are preferably formed in an insert which can be inserted into the nonwoven nozzle. The compression device is formed in this embodiment essentially by the fleece nozzle and the fleece nozzle insert. A commonly existing in known machines band hopper between the fleece nozzle insert and the calender rolls can be omitted in this embodiment.
Auch die Einfädeleinrichtung weist vorteilhafterweise mindestens eine Injektorbohrung auf, die mit einer zweiten Luftzufuhrleitung für Druckluft verbunden ist. Auch hier sind zwei Injektorbohrungen bevorzugt, um im Band vor Ablage in die Spinnkanne den gewünschten Drall zu erzeugen.The threading device also advantageously has at least one injector bore, which is connected to a second air supply line for compressed air. Again, two Injektorbohrungen preferred to produce the desired spin in the band before filing in the spinning can.
Die erste Luftzufuhrleitung und/oder die zweite Luftzufuhrleitung verlaufen besonders bevorzugt im Träger, da hierdurch keine platzintensiven und bei der Handhabung störenden Schläuche im Bedienraum vonnöten sind. Bei ansonsten vorhandenen Schläuchen kann sich des weiteren bei einem Bandstau an der Vliesdüse oder bei ähnlichen Störungen unerwünschtermaßen Fasermaterial an den Schläuchen absetzen, was das Handling weiter erschwert. Auch müsste beim Einsetzen von Teilen in die Betriebsposition auf die Schlauchverlegung geachtet werden.The first air supply line and / or the second air supply line particularly preferably run in the carrier, since this no space-intensive and disturbing in handling hoses in the control room are needed. In otherwise existing hoses can further at a Tape accumulation at the fleece nozzle or in similar disturbances undesirably deposit fiber material on the hoses, which further complicates the handling. Also, care should be taken when inserting parts in the operating position on the hose routing.
Die erste und die zweite Luftzufuhrleitung werden besonders bevorzugt von einer gemeinsamen, am Träger vorgesehenen Zufuhrspeisung gespeist, da dann nur eine einzige externe Luftzuführung zum Träger vorhanden sein muss. Vorteilhafterweise kommt hierbei an der Druckluftübertragungsstelle der Zufuhrspeisung keine Dichtung zum Einsatz kommt. Bevorzugt liegt der Träger stattdessen eng an der entsprechenden Druckluftübertragungsstelle an, beispielsweise mit Hilfe der oben genannten Zylinderlager.The first and the second air supply line are particularly preferably fed by a common supply feed provided on the carrier, since then only a single external air supply to the carrier must be present. Advantageously, no seal is used here at the compressed air transfer point of the feed supply. Preferably, the carrier is instead located close to the corresponding compressed air transfer point, for example with the aid of the cylinder bearings mentioned above.
Vorzugsweise sind die erste und die zweite Luftzufuhrleitung durch Bohrungen im Träger gebildet, wobei weiterhin bevorzugt eine Sammelleitung im Träger von der Zufuhrspeisung zu einer Abzweigung führt, von der die erste und die zweite Luftzufuhrleitung abzweigen.Preferably, the first and the second air supply line are formed by bores in the carrier, wherein furthermore preferably a manifold in the carrier from the feed supply leads to a branch from which the first and the second air supply line branch off.
Vorzugsweise ist die Menge der zugeführten Druckluft in beiden Luftzufuhrleitungen unabhängig voneinander einstellbar, ggf. sogar bis zum Schließen bzw. Unterbrechen einer der beiden Luftzufuhrleitungen. Hierfür kann eine manuelle Einstellmöglichkeit oder eine elektrisch gesteuerte oder geregelte Verstellung vorgesehen sein.Preferably, the amount of compressed air supplied in both air supply lines is independently adjustable, possibly even until closing or interrupting one of the two air supply lines. For this purpose, a manual adjustment or an electrically controlled or regulated adjustment can be provided.
Die beschriebene Luftzuführung in einem massiven Bauteil - insbesondere ausgeführt als Bohrungen, vorzugsweise in dem genannten Träger - zu den Injektorbohrungen der Verdichtungs- und/oder der Einfädeleinrichtung kann auch als eigener Erfindungsaspekt angesehen werden. Auf raumgreifende, anfällige Schlauchverbindungen zu den Injektorbohrungen kann verzichtet werden. Die Platzverhältnisse und die Zugriffszugänglichkeit werden hierbei optimiert und die Handhabbarkeit deutlich erhöht. Bei dieser Art von Luftzufuhrleitung(en) ist eine Ausgestaltung eines Trägers mit Anordnung sowohl der Verdichtungs- als auch die Einfädeleinrichtung nicht notwendig, aber selbstverständlich möglich. Auch die übrigen beschriebenen Ausgestaltungsmöglichkeiten (Zufuhrspeisung, Sammelleitung, von der Sammelleitung abgezweigte Luftzufuhrleitungen, Einstellbarkeit der Luftzufuhr, etc.) sind in diesem separaten Erfindungsaspekt als vorteilhafte Weiterbildungen eingeschlossen - unabhängig davon, ob überhaupt ein Träger vorhanden ist oder ob der Träger gemäß dem ersten Erfindungsaspekt ausgebildet ist. Auch kann es möglich sein, dass sowohl für die Verdichtungseinrichtung als auch für die Einfädeleinrichtung jeweils eine separate Halterung bzw. ein separater Träger vorgehen ist. Hierbei laufen dann vorzugsweise die Luftzufuhrleitungen in der jeweiligen Halterung.The described air supply in a solid component - in particular embodied as bores, preferably in the mentioned carrier - to the injector bores of the compression and / or the threading device can also be regarded as a separate invention aspect. Prolonged, vulnerable hose connections to the injector bores can be dispensed with. The space available and access accessibility are optimized and the handling is significantly increased. In this type of air supply line (s) is an embodiment of a carrier with arrangement both the compaction and the threading device not necessary, but of course possible. The other described design options (feed supply, manifold, branched from the manifold air supply lines, adjustability of air supply, etc.) are included in this separate aspect of the invention as advantageous developments - regardless of whether a carrier is present or whether the carrier according to the first aspect of the invention is trained. It may also be possible for a separate holder or a separate carrier to proceed both for the compacting device and for the threading device. In this case, then preferably run the air supply lines in the respective holder.
Die Erfindung betrifft gleichfalls eine Spinnereivorbereitungsmaschine, insbesondere eine Karde, Strecke oder Kämmmaschine, mit einem Streckwerk, wobei die Spinnereivorbereitungsmaschine eine Vorrichtung der zuvor geschilderten Ausgestaltung aufweist.The invention also relates to a spinning preparation machine, in particular a carding machine, track or combing machine, with a drafting system, wherein the spinning preparation machine has a device of the previously described embodiment.
Das Streckwerk der erfindungsgemäßen Spinnereivorbereitungsmaschine ist vorzugsweise geneigt angeordnet, wobei das oder die zu einem Faservlies ausgebreiteten Faserbänder in Laufrichtung gesehen schräg abwärts das Streckwerk durchlaufen. Das Streckwerk wird hierbei vorzugsweise von vorne - ggf. mit Hilfe eines Podests als Standerhöhung - bedient. Der Benutzer hat bei einer diesbezüglichen Ausführungsform mit beiden Händen, die links und rechts an dem Belastungsarm vorbeigreifen, Zugriff auf den Träger. An dem Belastungsarm sind üblicherweise die ihm zugewandte Kalanderwalze und die Oberwalzen aufgehängt.The drafting system of the spinning preparation machine according to the invention is preferably arranged inclined, wherein the or the fiber webs extended to a fiber web viewed in the direction of running obliquely downwards through the drafting system. The drafting system is preferably operated from the front - possibly with the help of a pedestal as Standerhöhung. The user, in one related embodiment, has access to the carrier with both hands passing past the loading arm on the left and right. The calender roll facing it and the upper rolls are usually suspended from the loading arm.
Das Streckwerk ist bei einer derartigen Anordnung vorzugsweise gegenüber der Horizontalen geneigt, bevorzugt mit einer Neigung zwischen 40° und 75° gegenüber der Horizontalen.The drafting system is preferably inclined with respect to the horizontal in such an arrangement, preferably with an inclination between 40 ° and 75 ° relative to the horizontal.
Aufgrund der Neigung des Streckwerks kann auf eine Umlenkoberwalze verzichtet werden, so dass das Streckwerk vorzugsweise als 3-über-3-Streckwerk ausgebildet ist, also ein Vor- und ein Hauptverzugsfeld ohne nachgeordnete Umlenkoberwalze aufweist.Due to the inclination of the drafting system can be dispensed with a Umlenkoberwalze, so that the drafting system is preferably designed as a 3-over-3 drafting, so has a pre-and a main drafting field without downstream Umlenkoberwalze.

Die Vliesdüse 21 verjüngt sich in Richtung der Kalanderwalzen 38, 48 und ragt mit einer stumpfen Spitze 8 in den von den Kalanderwalzen 38, 48 gebildeten oberen Spalt. Dies bedeutet, dass das Faserband FB nach Austritt aus der Vliesdüse 21 bzw. dem Vliesdüseneinsatz 26 sofort von den Kalanderwalzen 38, 48 erfasst wird und keine freien Wege durchlaufen muss, was ansonsten die Gefahr von Bandlaufstörungen erhöhen würde.The
Im Vliesdüseneinsatz 26 sind zwei schräg gegenüber der Vertikalen verlaufende, von außen bis ins Innere des Einsatzes 26 durchgehende Injektorbohrungen 27 vorgesehen, die zum Transport eines anfangs losen Faserbandendes durch den Einsatz 26 dienen. Die beiden Injektorbohrungen 27 werden mit Druckluft versorgt, die durch eine am Träger 2 vorgesehene Zufuhrspeisung 15 sichergestellt wird, wobei an der Druckluftübertragungsstelle vorliegend keine Dichtung zum Einsatz kommt. Die Zufuhrspeisung 15 versorgt eine im Träger 2 verlaufende Sammelleitung 17 mit Luft, die wiederum in eine erste Luftzufuhrleitung 18 mündet, die schließlich zu den Injektorbohrungen 27 führt. Die Leitungen 17, 18 sind als Bohrungen im Träger 2 ausgeführt.In

Drosselschraube 16b o.dgl. eingeschraubt, die den Übergang von der Sammelleitung 17 in die erste bzw. zweite Luftzufuhrleitung 18 bzw. 14 unterschiedlich weit verschließen kann. Auf diese Weise lässt sich die Luftzufuhr zu den Injektorbohrungen 18 bzw. 14 regulieren.

Die Erfindung wurde anhand eines Ausführungsbeispiels näher beschrieben. Innerhalb der Ansprüche sind weitere Ausgestaltungsmöglichkeiten realisierbar. Beispielsweise kann der Träger auch aus zwei oder mehreren Rahmenteilen bestehen, die miteinander verschraubt oder anderweitig fest und ggf. lösbar miteinander verbunden sind. Auch hierbei wird der Träger bevorzugt als Ganzes in seine Arbeitsstellung gebracht bzw. aus dieser entfernt.The invention has been described in more detail with reference to an embodiment. Within the claims further refinement possibilities can be realized. For example, the carrier can also consist of two or more frame parts, which are screwed together or otherwise firmly and possibly releasably connected to each other. Again, the carrier is preferably brought as a whole in its working position or removed from this.
