Description
Verfahren und Vorrichtung zum Lockern und Verziehen eines aus künstlicher Schnittfaser bestehenden Bandes Es ist bereits bekannt, Faserbänder, die aus künstlicher Schnittfaser (Stapelfaser) bestehen, dadurch zu verziehen, daß man diese gegebenenfalls in schräge Abschnitte geteilten Faserbänder zwischen zylindrischen Riffelwalzenpaaren mit verschiedener Arbeitsgeschwindigkeit hindurchlaufen läßt.Method and device for loosening and warping an artificial one Cut fiber existing tape It is already known, fiber tapes, which are made of artificial Cut fiber (staple fiber) exist, to be warped by the fact that one this, if necessary Sliver divided into inclined sections between cylindrical corrugated roller pairs can run through at different working speeds.
Nunmehr wurde gefunden, daß man ein überraschend gut gelockertes und verzogenes Band dadurch erzielt, daß man das Band durch Kegelrollerpaare führt. Durch die verschiedenen Oberflächengeschwindigkeiten auf den Kegeln werden die nebeneinanderliegenden Einzelfasern verschieden schnell in der Längsrichtung verschoben. Läßt man Faserbandabschnitte, auch wenn diese durch Schrägschnitt rautenförmige Form erhalten haben, durch iylindrisch geformte Walzen gehen, so findet diese Längsverschiebung nicht statt, und die weitgehende Lockerung auch verklebter Einzelfasern kann nicht erzielt werden.It has now been found that a surprisingly well loosened and warped tape achieved by leading the tape through pairs of cone rollers. Due to the different surface speeds on the cones, the adjacent Individual fibers shifted at different speeds in the longitudinal direction. If you leave sliver sections, even if these have been given a diamond-shaped shape by means of an oblique cut, by means of cylindrical formed rollers go, this longitudinal shift does not take place, and the extensive Loosening of even stuck individual fibers cannot be achieved.
Die Kegelroller haben zweckmäßig Längsriffelung.The tapered rollers suitably have longitudinal corrugation.
Die Arbeitsweise ist an Hand der beispielsweisen Darstellung in der Zeichnung erklärt. Fig. i gibt eine Seitenansicht, Fig. 2 eine Aufsicht der Vorrichtung.The working method is based on the example illustration in the Drawing explained. FIG. 1 shows a side view, FIG. 2 shows a plan view of the device.
Das bereits geschnittene Band wird durch das Zylinderpaar a, a' an das Kegelrollerpaar b, b' geliefert, welches den wesentlichen Bes -andteil -der Vorrichtung bildet. Es können mehrere Kegelrollerpaare hintereinander und auch um einen beliebigen Winkel verdreht angeordnet sein. Das Band wird (Fig. 2) auf der linken Seite des Kegelrollerpaares entsprechend der größeren Oberflächengeschwindigkeit schneller verzogen als auf der rechten Seite. Hinter den Kegelrollerpaaren wird das verzogene Band in üblicher Weise über `Unterlagen c ti. dgl. durch gewöhnliche Rollenpaare d, d' weiterbefördert.The already cut tape is delivered through the cylinder pair a, a ' to the conical roller pair b, b' , which forms the essential part of the device. Several pairs of cone rollers can be arranged one behind the other and rotated by any desired angle. The tape is warped (Fig. 2) on the left side of the cone roller pair, corresponding to the greater surface speed, faster than on the right side. Behind the pairs of cone rollers, the warped tape is applied in the usual way using `` documents c ti. Like. Conveyed further by ordinary pairs of rollers d, d '.
Bei Anwendung derartiger Vorrichtungen zeigt es sich, daß die Stapel des Bandes hinter der Klemmstelle jedes Kegelrollerpaares gegeneinander verschoben sind, und zwar findet an der breiteren Seite des Kegelrollers eine stärkere Verschiebung der Fasern statt als an der schmäleren Seite, 'entsprechend den verschiedenen Umfangsgeschwindigkeiten. Will man dieses Voreilen der einen Seite in dem Faserband wieder kompensieren, so wird hinter dem ersten Kegelrollerpaar ein um 18o° verdrehtes zweites Kegelrollerpaar eingeschaltet. Ein zweites oder drittes Kegelrollerpaar kann auch in einem Winkel von 9o° angeordnet sein.When using such devices, it is found that the stack of the belt behind the clamping point of each pair of tapered rollers against each other there is a greater shift on the wider side of the cone roller of the fibers instead of on the narrower side, 'according to the different circumferential speeds. If you want to compensate for this advance of one side in the sliver, so After the first pair of tapered rollers, a second pair of tapered rollers is turned through 180 ° switched on. A second or third pair of cone rollers can also be used at an angle be arranged from 9o °.
Durch diese Bearbeitung erhalten die Schnittfasern untereinander eine bessere Bindung, d.' h. es wird ein gut zusammenhängendes Band erzielt. Dieses Band kann durch einen Trichter verdichtet und nach einem Verziehen auf einer Strecke im üblichen Spinnprozeß zu Garn versponnen werden.This processing gives the cut fibers one another better bond, d. ' H. a well-connected band is achieved. This tape can be compacted through a funnel and after being warped on a stretch are spun into yarn in the usual spinning process.
