Description
Die Erfindung betrifft eine Spinnmaschine, insbesondere Ringspinnmaschine nach dem Oberbegriff des Patentanspruchs 1 sowie ein Spinnverfahren nach dem Oberbegriff des Patentanspruchs 24.The The invention relates to a spinning machine, in particular ring spinning machine according to the preamble of claim 1 and a spinning process according to the preamble of claim 24.
Bei
einem bekannten Ringspinnverfahren bzw. bei einer bekannten Ringspinnmaschine
dieser Art (
Durch die aerodynamische Verdichtung der Fasern, die dem Hochverzug folgt, wird ein Kompaktfaserstrang von rund 1 mm Breite oder weniger erzielt, welche gleichzeitig die Basis des sich an den Drehungssperrspalt anschließenden Spinndreiecks bildet. Damit reduziert sich konsequenterweise auch die Höhe des Spinndreiecks. Somit kann durch die Tatsache der aerodynamischen Bündelung der Fasern Einfluß auf die Eindrehung des Faserverbandes genommen werden.By the aerodynamic compaction of the fibers following the high distortion a compact fiber strand of about 1 mm width or less is achieved, Which at the same time the basis of the turn-lock gap subsequent Forming a spinning triangle. Consequently, this also reduces the Height of Spinning triangle. Thus, by the fact of the aerodynamic bundling the fibers influence the recess of the fiber structure are taken.
Üblicherweise werden bei Ringspinnmaschinen Drei-ZylinderStreckwerke verwendet, wobei das am Beginn des Hochverzugsfelds vorgesehene mittlere Zylinderpaar im allgemeinen mit Doppelriemchen ausgerüstet ist, die bis nahe an den Eintrittsspalt des Ausgangswalzenpaars reichen.Usually three-cylinder drafting systems are used in ring spinning machines, wherein the provided at the beginning of the high draft field middle cylinder pair is generally equipped with Doppelriemchen, close to the Entrance gap of the output roller pair range.
Die
Verzüge
von mit einer Flyerlunte gespeisten Drei-Zylinder-Streckwerken liegen
je nach Garnfeinheit bei 25- bis 50-fach, wobei die höheren Verzüge feineren
Garnnummern entsprechen. Man hat auch schon zwischen den Enden der
Riemchen im Hauptverzugsfeld und dem Klemmspalt zwischen den Ausgangszylindern
des Streckwerks mechanische Kondensoren zur Bündelung des Faserverbandes
verwendet (
Um den Verschleiß innerhalb des Mehrstufen-Streckwerks herabzusetzen, ist im allgemeinen vor demselben eine Changiervorrichtung vorgesehen, welche den in das Mehrstufen-Streckwerk eintretenden Faserverband über eine Breite von etwa 6 bis 10 mm mit einer zeitlichen Periode von größenordnungsmäßig 1 min changieren läßt. In einem derartigen Fall ist es jedoch problematisch, eine als Schrägschlitz ausgebildete Saugzone zu verwenden, welche den grundsätzlichen Vorteil aufweist, daß der Faserverband an der in Förderrichtung gesehen vordere Kante des Schrägschlitzes sowohl aerodynamisch als auch mechanisch gebündelt wird.Around the wear inside of the multi-stage drafting system is generally present provided a traversing device, which in the Multi-stage drafting entering fiber structure over a width of about 6 to 10 mm with a time period of the order of 1 min let change. In one However, such a case, it is problematic as a slanted slot trained to use the suction zone, which is the fundamental Advantage that the fiber structure at the in the conveying direction seen front edge of the slanted slot both aerodynamically and mechanically bundled.
Im Falle einer Changierung wird die Wirkung des Schrägschlitzes zeitlich verändert, da sich der Faserverband mehr oder weniger lang an der vorderen Kante entlang bewegt.in the Trap of a traversing becomes the effect of the slanted slot changed over time, because the fiber bandage is more or less long at the front Edge moved along.
Das Ziel der vorliegenden Erfindung besteht darin, eine Ringspinnmaschine der eingangs genannten Gattung sowie ein diesbezügliches Verfahren zu schaffen, welche auch bei sehr hohen Verzügen in dem Mehrstufen Streckwerk eine einwandfreie kombinierte aerodynamische Bündelung des Faserverbandes innerhalb der verzugsfreien Kondensationszone gewährleistet.The The aim of the present invention is a ring spinning machine of the type mentioned in the introduction and a related method, which also at very high delays in the multi-stage drafting system a flawless combined aerodynamic bundling of the fiber structure within the distortion-free condensation zone guaranteed.
Zur Lösung dieser Aufgabe ist eine Spinnmaschine mit den Merkmalen des Anspruches 1 sowie ein Verfahren mit den Merkmalen des Anspruchs 28 vorgesehen. Vorteilhafte Weiterbildungen der Erfindung sind durch die Unteransprüche gekennzeichnet.to solution This object is a spinning machine with the features of the claim 1 and a method having the features of claim 28 are provided. Advantageous developments of the invention are characterized by the subclaims.
