Description

Verfahren zur Gewinnung von verspinnbaren Langfasern aus Grünhanfstengeln, insbesondere Grünsamenhanfstengeln Die Erfindung betrifft ein Verfahren zur Gewinnung von verspinnbaren Langfasern aus Grünhanfstengeln, insbesondere Grünsamenhanfstengeln.Process for the production of spinnable long fibers from green hemp stalks, in particular green seed hemp stalks The invention relates to a method for obtaining of spinnable long fibers from green hemp stalks, in particular green seed hemp stalks.

Um aus solchen Stengeln Langfasern zu gewinnen, ist es bisher üblich, den Stengel zu brechen, zu schwingen und zu hecheln. Auch ist es bekannt, am Ende einer Faserbearbeitungsmaschine die Langfasern in Form von Handvollen absatzweise abzunehmen. Bei solcher Faserbearbeitung wird neben der Langfaser in größerem Umfang auch Werg erzeugt.In order to obtain long fibers from such stalks, it has hitherto been customary to to break the stalk, to swing and pant. Also it is known in the end a fiber processing machine the long fibers in the form of handfuls in batches to decrease. In such fiber processing, long fibers are used to a greater extent also produced tow.

Um im fortlaufenden Arbeitsgang aus Grünhanfstengeln, insbesondere Grünsamenhanfstengeln, ausschließlich verspinubare Langfasern in Form von Handvollen zu gewinnen, praktisch also einen Anfall von Werg zu vermeiden, wird gemäß der Erfindung das faserhaltige Gut unter Einhaltung .der Parallellage zunächst in fortlaufendem Arbeitsgang geknickt und geschabt und das gewonnene Faservlies unter Erteilung eines falschen Drahtes zu einem strangartigen Gebilde verdichtet und abgelegt; anschließend wird eine Vielzahl in 'dieser Weise gewonnener Langfaserstränge nebeneinanderliegend auf ein aus umlaufenden Walzen bestehendes Nadelbett aufgelegt und absatzweise so weit gefördert, bis die Fasern zwischen den an das Nadelbett anschließenden Glattwalzen hervorstehen, worauf sie während des Stillstandes der Nadelwalzen jeweils von einer Zange :erfaßt und aus dem Nadelbett herausgezogen werden. Die Nadelwalzen können in der Bearbeitungsrichtung zunehmend dichtere Benadelung aufweisen. Bei der Bearbeitung in dem an sich bekannten Nadelbett werden :die roh gewonnenen Bündelfasern weitgehend zerteilt und die restlichen Schebenteile von den Fasern entfernt. Auch findet bei dieser Bearbeitung eine der Vielzahl der vorgelegten Stränge entsprechende Durchmischung der Fasern statt. Die in der angegebenen Weise gewonnenen Handvollen dienen zur Herstellung von Garnen hoher Nummern. F In der Zeichnung ist schematisch eins Eicu--`' richtung zur Durchführung des Verfahrei@s gemäß der Erfindung beispielsweise darA°#;" stellt.In order to be made from green hemp stalks, in particular Green seed hemp stalks, exclusively spinable long fibers in the form of handfuls to win, so practically to avoid an attack of tow, is according to the invention the fiber-containing material in compliance with the parallel position initially in continuous Operation kinked and scraped and the obtained fiber fleece with a false wire compacted into a strand-like structure and deposited; afterward a large number of long fiber strands obtained in this way are lying next to one another placed on a needle bed consisting of rotating rollers and intermittently like this far conveyed until the fibers between the smooth rollers adjoining the needle bed protrude, whereupon they each from one during the standstill of the needle rollers Forceps: grasped and pulled out of the needle bed. The needle rollers can have increasingly denser needling in the machining direction. When editing in the needle bed known per se: the raw bundle fibers obtained largely divided and the remaining debris removed from the fibers. Also takes place at this processing a mixing corresponding to the large number of strands presented the fibers instead. The ones specified in the Wisely won handfuls are used to produce high-numbered yarns. F in the drawing is schematic one Eicu - '' direction for carrying out the method according to the invention, for example darA ° #; "represents.

Die Grünhanfstengel werden bei I ununterbrochen in der Bearbeitungsrichtung quer zur Achse :der Brechwalzen zwischen den Riffelwalzenpaaren b hindurchgeführt und gelangen zu einem, Schabewalzenpaar s1. Anschließend folgen zwei Brechwalzenpaare bl. Dahinter wirken auf :das Fasergut wieder Schabewalzen s2 ein, auf die noch die Brechwalzenpaare b2 folgen. Dann gelangt das in dieser Weise gewonnene Faservlies zu einem Drehrohr d, das ihm unter strangartiger Verdichtung falschen Draht erteilt. Hinter dem Drehrohr wirkt auf den Faserstrang ein Abzugswalzenpaar f ein. Der Faserstrang wird dann in eine Kanne l abgelegt. Eine größere Anzahl solcher Faserstränge wird anschließend einem Nadelbett vorgelegt, das aus unteren Nadelwalzen u und oberen Glatt-oder Nadelwalzen o besteht. Anschließend an das Nadelbett ist ein Glattwalzenpaar z angeordnet. Die Nadelwalzen u und o und die Glattwalzen z werden im Betrieb gleichmäßig absatzweise derart angetrieben, daß sie jeweils die Faserbänder in bestimmter Länge so weit vorwärts schalten, bis die Fasern zwischen den an das Nadelbett anschließen-,den Glattwalzen hervorstehen. Während des `thfllstandes der Nadelwalzen werden die I;ä.sern anschließend von einer Zange erfaßt, äxjrs dem Nadelbett in Richtung P herausge-"z6gen und abgelegt.At I, the green hemp stalks become uninterrupted in the processing direction across the axis: the crushing rollers passed between the corrugated roller pairs b and arrive at a pair of scraper rollers s1. This is followed by two pairs of crushing rollers bl. Behind it act on: the fiber material again scraper rollers s2, on which the The crushing roller pairs b2 follow. Then the fiber fleece obtained in this way arrives to a rotary tube d, which gives him the wrong wire with strand-like compression. Behind the rotary tube, a pair of take-off rollers f acts on the fiber strand. The fiber strand is then placed in a can l. A larger number of such fiber strands will then submitted to a needle bed, which consists of lower needle rollers u and upper Smooth or needle rollers o consists. Subsequent to the needle bed is a pair of smooth rollers z arranged. The needle rollers u and o and the smooth rollers z become uniform during operation intermittently driven in such a way that they each have the slivers of a certain length Switch forward until the fibers connect to the needle bed between the Smooth rollers protrude. While the needle rollers are still in the oil, the then grasped by a pair of pliers, pulled out axially of the needle bed in direction P. and filed.
