Riemchenwaizen geführten Doppeiriemchen und einem Riemchenwaizen led Doppeiriemchen and a
Ausgangsdruckwalzenpaar, wobei die Riemchenwalzen und das Output pressure roller pair, wherein the Riemchenwalzen and the
Ausgangsdruckwalzenpaar jeweils eine obere Druckwalze und eine elektromotorisch angetriebene Unterwalze aufweisen und die Walzen auf der Vorderseite einer Grundplatte angeordnet sind, während ihre Achsen durch die Grundplatte hindurchgeführt sind und die Antriebsmittel für die Unterwalzen zumindest teilweise auf der Rückseite der Grundplatte angeordnet sind. Output pressure roller pair each having an upper pressure roller and an electric motor driven lower roller and the rollers are arranged on the front side of a base plate, while their axes are passed through the base plate and the drive means for the lower rollers are at least partially disposed on the back of the base plate.
Ein solches Streckwerk ist bereits aus der WO 2010/028513 AI bekannt. Es dient dazu, aus einem Vorgarn einen verzogenen Faserverband herzustellen und diesen den Nadeln der Strickmaschine direkt zuzuführen. Bei diesen kombinierten Spinn-Strickmaschinen wird daher auf die Such a drafting system is already known from WO 2010/028513 AI. It serves to produce a distorted fiber structure from a roving and to supply it directly to the needles of the knitting machine. In these combined spinning-knitting machines is therefore on the

Gestrickstücke. Die Streckwerke dieser Spinn-Strickmaschinen sind wie die Streckwerke von Spinnmaschinen Faserflug ausgesetzt, der zu Verschmutzungen und Betriebsstörungen führen kann. Insbesondere können sich Fasern oder Abrieb im Spalt zwischen den fliegend an der Grundplatte gelagerten Walzen und der Grundplatte ansammeln und zu Störungen des Betriebs des Streckwerks führen. Bei dem bekannten Streckwerk wird daher die Rückseite der Grundplatte mit einem Gehäuse luftdicht abgedeckt und dort Druckluft eingeführt, die durch Bohrungen in der Grundplatte zum Spalt zwischen den Unterwalzen und der Vorderseite der Grundplatte geleitet wird. Die Druckluft ist damit in der Lage, die sich im Spalt befindlichen Fasern auszublasen, sodass sich diese nicht festsetzen können. Die abgeblasenen Fasern können sich anschließend jedoch an anderen Maschinenteilen festsetzen. Knitted pieces. The drafting systems of these spinning-knitting machines are like the drafting of spinning machines exposed to fiber fly, which can lead to contamination and malfunction. In particular, fibers or abrasion may accumulate in the nip between the rolls resting on the base plate and the base plate and lead to disturbances in the operation of the drafting system. In the known drafting system, therefore, the back of the base plate is hermetically covered with a housing and there introduced compressed air, which is passed through holes in the base plate to the gap between the lower rollers and the front of the base plate. The compressed air is thus able to blow out the fibers located in the gap, so that they can not settle. However, the blown-off fibers can then settle on other machine parts.
Die EP 0 532 457 AI beschreibt ein Streckwerk für Spinnmaschinen, bei dem die Walzenpaare an einem geschlossenen Antriebsgehäuse fliegend gelagert sind. Die Streckwerkswalzen sind von einem auf der Zufuhrseite des Vorgarns offenen Gehäuse abgedeckt. In das Antriebsgehäuse wird Druckluft eingeleitet, das durch für die Lagerung der Walzenwellen im Antriebsgehäuse vorgesehene Durchbrüche zu den Streckwerkwalzen im offenen Gehäuse strömen kann. Außerhalb des offenen Gehäuses ist eine Absaugung angeordnet, die über eine Schlauchverbindung mit dem offenen Gehäuse verbunden ist. Diese Absaugung ist jedoch in ihrer Wirkung stark eingeschränkt, da die Schlauchverbindung an einer von den Streckwerkwalzen weit entfernten Stelle in das offene Gehäuse mündet. Außerdem ist die Bauweise dieses Streckwerks sehr groß, sodass dieses Streckwerk nicht bei Spinn-Strick-Maschinen eingesetzt werden kann. Die Aufgabe der vorliegenden Erfindung besteht darin, ein Streckwerk fürEP 0 532 457 A1 describes a drafting system for spinning machines, in which the pairs of rollers are mounted in a floating manner on a closed drive housing. The drafting rollers are covered by a housing open on the feed side of the roving. In the drive housing compressed air is introduced, which can flow through provided for the storage of the roller shafts in the drive housing openings to the drafting rollers in the open housing. Outside the open housing, a suction is arranged, which is connected via a hose connection with the open housing. However, this suction is severely limited in its effect, since the hose connection opens at a location far from the drafting rollers in the open housing. In addition, the design of this drafting system is very large, so this drafting system can not be used in spinning-knitting machines. The object of the present invention is to provide a drafting system for
Spinn-Strickmaschinen bereit zu stellen, das durch Faserflug und Abrieb auftretende Probleme weitgehend vermeidet. Spinning knitting machines to provide that largely avoids problems caused by fluff and abrasion.

Ausgangsdruckwalzenpaar, wobei das Riemchenwalzenpaar und das Ausgangsdruckwalzenpaar jeweils eine obere Druckwalze und eine elektromotorisch angetriebene Unterwalze aufweisen und die Walzen auf der Vorderseite einer Grundplatte angeordnet sind, während ihre Achsen durch die Grundplatte hindurchgeführt sind und die Antriebsmittel für die Unterwalzen zumindest teilweise auf der Rückseite der Grundplatte angeordnet sind, das dadurch gekennzeichnet ist, dass an der Oberwalze des Ausgangsdruckwalzenpaares und der Oberwalze des Output pressure roller pair, wherein the Riemchenwalzenpaar and the Ausgangsdruckwalzenpaar each having an upper pressure roller and an electric motor driven lower roller and the rollers are arranged on the front side of a base plate, while their axes are passed through the base plate and the drive means for the lower rollers at least partially on the back of the base plate are arranged, which is characterized in that on the top roller of the output pressure roller pair and the top roller of the
Riemchenwalzenpaares eine sich über beide Oberwalzen erstreckende Absaugung angeordnet ist. Es kann zudem ein Eingangsdruckwalzenpaar vorgesehen sein. Riemchenwalzenpaares is arranged over both upper rollers extending suction. It may also be provided an input pressure roller pair.
Das erfindungsgemäße Streckwerk verzichtet auf ein die The drafting device according to the invention dispenses with a
Streckwerkwalzen zumindest teilweise abdeckendes Gehäuse und setzt stattdessen eine Absaugung gezielt nahe am Entstehungsort für den Faserflug, im Bereich der beiden dem Streckwerksausgang am nächsten liegenden Oberwalzen ein. Die Absaugung erstreckt sich dabei über beide Walzen. Eine der Oberwalzen ist eine Riemchenwalze. Somit dient die Absaugung auch der Reinigung der Riemchen. Auch von außerhalb eindringendem Staub kann mit der Absaugung zuverlässig aus dem Streckwerk entfernt werden. Durch den Verzicht auf die Drawframe rollers at least partially covering housing and instead uses a suction targeted near the place of origin for the fiber fly, in the area of the two drafting the top closest to the top rollers. The suction extends over both rollers. One of the top rollers is a Riemchenwalze. Thus, the suction also serves to clean the straps. Also from outside penetrating dust can be reliably removed with the suction from the drafting system. By renouncing the
Gehäusekapselung der Streckwerkwalzen sind diese auch stets für Wartungsarbeiten und zur Kontrolle des Verziehens des Faserverbandes frei zugänglich. Der benötigte Einbauraum für das Streckwerk ist gering, sodass dieses problemlos für Spinn-Strick-Maschinen eingesetzt werden kann. Enclosure encapsulation of the drafting rollers are these always for maintenance and to control the distortion of the fiber structure freely accessible. The required installation space for the drafting system is low, so that it can be easily used for spinning-knitting machines.
Die Wirkungsweise der Absaugung kann weiter optimiert werden, indem die Absaugung zumindest die Ausgangsoberwalze an ihrem freien Ende zumindest teilweise überdeckt. Das Absaugen wird dadurch noch stärker auf die Walzen konzentriert. Außerdem verhindert die teilweise seitliche Abdeckung der Oberwalze ein Entweichen loser Fasern und Flusen zur Seite hin. The mode of action of the suction can be further optimized by the suction at least partially covers at least the output top roller at its free end. The suction is thereby concentrated even more on the rollers. In addition, the partial lateral cover of the top roller prevents leakage of loose fibers and lint to the side.
Auch beim erfindungsgemäßen Streckwerk kann die Rückseite der Even with the drafting system according to the invention, the back of the
Grundplatte zumindest teilweise durch einen Gehäusedeckel luftdicht abgedeckt sein, der mit mindestens einer Zuführöffnung für Druckluft versehen ist, und die Grundplatte Durchgangsöffnungen für die Druckluft aufweisen. Damit kann Luft von der Streckwerkrückseite her und durch die Öffnungen in der Grundplatte hindurch zu den Streckwerkwalzen geleitet werden und dort ein Festsetzen von Abrieb, Flusen oder Staub im Zusammenwirken mit der Absaugung zuverlässig verhindern. Base plate be at least partially hermetically covered by a housing cover, which is provided with at least one supply port for compressed air, and the base plate through-openings for the compressed air. This air can be passed from the drafting device rear side and through the openings in the base plate to the drafting rollers and reliably prevent the setting of abrasion, lint or dust in cooperation with the suction.
Dabei ist es von besonderem Vorteil, wenn die Durchgangsöffnungen in der Grundplatte von Achslöchern für die Achsen der Oberwalzen gebildet sind, durch die die Oberwaizenachsen mit Spiel hindurchgeführt sind. Auf diese Weise gelangt die Druckluft direkt in den schmalen Spalt zwischen den Walzenkörpern der Oberwalzen und der Grundplatte und von oben her auch in den entsprechenden Spalt zwischen den Unterwalzenkörpern und der Grundplatte und kann diese Spalte daher zuverlässig von It is particularly advantageous if the passage openings are formed in the base plate of the axial holes for the axes of the top rollers, through which the Oberwaizenachsen are passed with play. In this way, the compressed air passes directly into the narrow gap between the roller bodies of the top rollers and the base plate and from above into the corresponding gap between the lower roller bodies and the base plate and can therefore reliably from
Ansammlungen von Fasern oder Staub freihalten. Dem Ausgangswalzenpaar kann mindestens eine Düse zur Aufnahme des verstreckten Faserverbandes nachgeordnet sein, mit der dem Keep accumulations of fibers or dust free. The output roller pair can be arranged downstream of at least one nozzle for receiving the stretched fiber structure, with the
Faserverband ein Drall versetzt werden kann. Bei dieser Ausgestaltung des Streckwerks ist es vorteilhaft, wenn die Absaugung bei einem Fiber Association can be offset a twist. In this embodiment of the drafting system, it is advantageous if the suction at a
Verstopfe der mindestens einen Düse den Faserverband absaugt. Der Faserverband kann sich dadurch nicht im Streckwerk stauen und zu Verunreinigungen oder gar Beschädigungen des Streckwerks führen. Clogging of at least one nozzle sucks the fiber structure. As a result, the fiber structure can not accumulate in the drafting system and lead to contamination or even damage to the drafting system.
Weiter ist es möglich, auch die Vorderseite der Grundplatte zumindest bereichsweise mit einem Gehäusedeckel abzudecken. Dies ist Further, it is also possible to cover the front of the base plate at least partially with a housing cover. This is
insbesondere dann von Vorteil, wenn sich die Antriebsmotoren für die Unterwalzen ebenfalls auf der Vorderseite der Grundplatte befinden und durch den Gehäusedeckel abgedeckt werden und damit vor especially advantageous if the drive motors for the lower rollers are also on the front of the base plate and covered by the housing cover and thus before
Verunreinigungen geschützt sind. Contaminants are protected.

Riemchenwalzenpaar 14, 15 sowie ein Ausgangswalzenpaar 16, 17 fliegend angeordnet sind. Zwischen den Walzenpaaren 12, 13, 14, 15 und 16, 17, bei welchen jeweils die Unterwalze motorisch angetrieben ist, wird ein hier nicht näher dargestelltes Vorgarn aufgrund der Riemchenwalzenpaar 14, 15 and an output roller pair 16, 17 are arranged flying. Between the pairs of rollers 12, 13, 14, 15 and 16, 17, in which in each case the lower roller is driven by a motor, a not shown here in detail roving due to
unterschiedlichen Geschwindigkeiten der different speeds of the
Walzenpaare 12, 13, 14, 15, 16, 17 zu einem Faserverband verzogen. Am Ausgang des Ausgangswalzenpaares 16,17 ist eine Düse 18 mit einem Transportrohr 19 angeordnet, die den Faserverband zu einer hier ebenfalls nicht gezeigten Strickmaschine, vorzugsweise einer Rundstrickmaschine weiterleiten. Weiter ist an der Vorderseite 11.1 der Grundplatte 11 eine Absaugung 20 angeordnet, die sich über die Oberwalzen 17 und 15 des Ausgangswalzenpaares 16, 17 und des ausgangsseitigen  Roller pairs 12, 13, 14, 15, 16, 17 warped to a fiber structure. At the output of the pair of output rollers 16,17 a nozzle 18 is arranged with a transport tube 19, which forward the fiber structure to a knitting machine, also not shown here, preferably a circular knitting machine. Further, an extraction 20 is disposed on the front side 11.1 of the base plate 11, which extends over the top rollers 17 and 15 of the pair of output rollers 16, 17 and the output side
Riemchenwalzenpaares 14, 15 erstreckt. Sie ist damit in der Lage, Flusen, Staub und Abrieb, die beim Verziehen des Vorgarns entstehen, am Riemchenwalzenpaares 14, 15 extends. It is thus able to lint, dust and abrasion, which arise when warping the roving on

Insbesondere aus der vergrößerten Detailansicht in Fig. 2 ist zu erkennen, dass die Absaugung 20 die Ausgangsoberwalze 17 auch seitlich übergreift, sodass auch seitlich austretende Fasern oder Flusen sicher erfasst werden können. Aus dem Schnittbild in Fig. 3 ist ersichtlich, dass die Absaugung 20 zudem derart angeordnet ist, dass bei einer Verstopfung der Düse 18 der produzierte Faserstrang von der Absaugung 20 zuverlässig abgesaugt werden kann. Ein unterer Teil 20.1 der Absaugung 20 grenzt dazu unmittelbar an die Düse 18 an. In particular, from the enlarged detail view in Fig. 2 it can be seen that the suction 20, the output upper roller 17 also overlaps laterally, so that laterally emerging fibers or lint can be detected safely. From the sectional view in Fig. 3 it can be seen that the suction 20 is also arranged such that when a blockage of the nozzle 18 of the produced fiber strand can be reliably sucked from the suction 20. A lower part 20.1 of the suction 20 directly adjoins the nozzle 18 for this purpose.
