Description

Es .ist bekannt, verzugsfähige Faserbänder aus Bündeln künstlicher Fäden dadurch herzustellen, daß man die Fadenbündel zwischen Walzenpaaren zerreißt oder zerschneidet und ' dann unmittelbar darauf die so entstandenen Stapelabschnitte zu den angestrebten Faserbändern zusammenschließt. Bei den bekannten Verfahrensweisen hat sich jedoch der Übelstand gezeigt, daß weder beim Zerreißen noch beim Zerschneiden alle im Fadenbündel vorhandenen Fäden schon durch einen einzigen Reiß-oder Schneideprozeß restlos und ausnahmslos in Fasern zerlegt werden. Vielmehr bleiben noch immer einige Fäden unzertrennt, weshalb man gezwungen ist, noch einen besonderen Arbeitsgang für das Zerlegen auch der restlichen Fäden nachzuschalten. Dieser besondere Arbeitsgang muß jedoch die besondere Bedingung erfüllen, daß nicht auch die schon in brauchbarer Länge vorhandenen Fasern miterfaßt und in unerwünscht kurze Fasern weiterzerlegt werden.It is known that warpable fiber ribbons from bundles of artificial fibers Produce threads by tearing the thread bundles between pairs of rollers or cut up and then immediately afterwards the stacked sections thus created joins together to form the desired slivers. In the known procedures However, the disadvantage has shown that neither when tearing nor when cutting all threads present in the thread bundle by a single tearing or cutting process are completely and without exception broken down into fibers. In fact, there are still a few The threads are not severed, which is why you are forced to do another special operation for cutting the remaining threads. This particular operation must, however, meet the special condition that the already usable Length of existing fibers also recorded and further broken down into undesirably short fibers will.

Um nun das Zertrennen der restlichen Fäden bzw. von unbrauchbaren langen Fasern zu erleichtern, werden erfindungsgemäß die die Stapelabschnitte bildenden Fasern aus der durch noch unzertrennte Fäden bzw. die langen Fasern gegebenen Ebene vorübergehend abgelenkt und dadurch die Fäden bzw. langen Fasern freigelegt, die alsdann ebenfalls zerlegt werden, worauf die neuentstandenen Fasern mit den anderen vereinigt und zu einem verzugsfähigen Faserband zusammengeschlossen werden. Das Ablenken der Fasern wird durch einen Luftstrom pneumatisch bewirkt, und dabei werden diese Fasern auf ein endloses Transportsiebband gelegt, welches dann die Fasern zusammen mit den neugebildeten dem nächstfolgenden Walzenpaar od. dgl. zuführt.In order to cut the remaining threads or those that are unusable To facilitate long fibers, according to the invention, those forming the stacking sections are used Fibers from the plane given by the still unseparated threads or the long fibers temporarily deflected and thereby exposed the threads or long fibers that then also be dismantled, whereupon the newly formed fibers with the others be combined and joined together to form a draftable sliver. That Deflection of the fibers is effected pneumatically by a stream of air, and thereby are these fibers are placed on an endless conveyor belt, which then carries the fibers together with the newly formed pair of rollers or the like.

An Hand der Zeichnung sei das Verfahren nach der Erfindung an einem Ausführungsbeispiel näher erläutert.The method according to the invention is based on the drawing Embodiment explained in more detail.

Ein etwa 2ooo Denier starkes Bündel künstlicher Fäden i wird um die Walzen :2 und 3 herumgeführt und sodann_ zwischen den Walzenpaaren 3, 3' und q., ,4' in Stapelähschriitte zerrissen. Ein endloses Band g sorgt für einen sicheren Weitertransport der Fasern. Die vom Zerreißprozeß zwischen den Walzenpaaren 3, 3' und 4, . noch nicht miterfaßten Fäden 6 laufen in gespanntem Zustande zum Walzenpaar 7, 7' geradlinig weiter. Die Fasern dagegen werden durch das Ansaugrohr 8 gegen die Oberfläche eines endlosen Siebbandes 9 gesogen und dann im spitzen Winkel zu den Fäden 6 in Richtung auf das Walzenpaar 7, 7' weiterbefördert. Durch die Ablenkung der bereits zwischen den Walzenpaaren 3, 3' und q., q.' erzeugten Fasern werden die noch unzerrissenen Fäden vollkommen freigelegt und können nunmehr durch ein periodisch auf und nieder gehendes Messer io leicht und sicher ebenfalls in Fasern zerlegt werden. Die die Walzen 7, 7' verlassenden Fasern werden durch das trichterförmige Verdichterröhrchen i i in üblicher Weise zu einem verzugsfähigen Faserband usammengeschlossen.An approximately 2,000 denier bundle of artificial threads is wrapped around the Rollers: 2 and 3 led around and then_ between the pairs of rollers 3, 3 'and q., , 4 'torn in pile stitching. An endless belt g ensures a safe Further transport of the fibers. The from the tearing process between the roller pairs 3, 3 ' and 4,. Threads 6 that have not yet been captured run in a tensioned state to the pair of rollers 7, 7 'straight ahead. The fibers, on the other hand, are counteracted by the suction pipe 8 the surface of an endless screen belt 9 is sucked and then closed at an acute angle the threads 6 are conveyed further in the direction of the pair of rollers 7, 7 '. Because of the distraction the already between the roller pairs 3, 3 'and q., q.' produced fibers the still unbroken threads are completely exposed and can now go through a Periodically up and down knife io easily and safely also in fibers be disassembled. The fibers leaving the rollers 7, 7 'are through the funnel-shaped Compressor tubes i i closed in the usual way to form a draftable sliver.
