Description
Vorrichtung zum Gewinnen verspin N.'asern aus faserhaltigen Baststengeln Es sind Vorrichtungen zum Gewinnen verspinnbarer Fasern aus faserhaltigen Baststengeln bekannt,, in denen die Stengel in der Längsrichtung gespalten und aufgeklappt werden und in denen anschließend das Holz von den Rindenbändern abgenommen wird. Um die Mengenleistung solcher Vorrichtungen zu steigern und die Betriebssicherheit zu erhöhen, ist die Vorrichtung gemäß der Erfindung derart ausgebildet, daß die Stengel durch ein Walzenpaar der in entsprechender Breite ausgeführten keilförmigen Messerschneide in Schräglage zugeführt werden uns daß unmittelbar hinter dieser Schneide für die Stengelhälften zwei Quetschwalzenpaare angeordnet sind, an die sich Führungsmittel zum Zuführen der Bastbänder zu einer Rolle und zum Abbiegen um diese Rolle anschließen, neben der endlose Fördermittel zum Ziehen der Bänder über diese Rolle angeordnet sind, während an der der Rolle gegenüberliegenden Seite der Bastbänder je ein Trennmesser mit entgegen dem Bandvorschub gerichteter Schneide angreift.Apparatus for extraction spun fibers from fiber-containing bast stalks They are devices for obtaining spinnable fibers from fiber-containing bast stems known, in which the stalks are split lengthways and unfolded and in which the wood is then removed from the bark bands. To the To increase the volume output of such devices and to increase operational reliability, the device according to the invention is designed such that the stalk through a pair of rollers with a wedge-shaped knife edge of the same width are fed to us in an inclined position that immediately behind this cutting edge for the Stalk halves two pairs of squeeze rollers are arranged on which guide means to feed the raffia tapes to a roll and to turn around this roll, arranged next to the endless conveyor for pulling the belts over this roller are, while on the side of the bast strips opposite the roll there is a separating knife attacks with the cutting edge directed against the tape feed.
Die Vorrichtung gemäß der Erfindung ist schematisch in der Zeichnung dargestellt. Die Stengel i werden rriit den Wurzelenden voraus den Einführwalzen 2, 2' in Schräglage, beispielsweise unter 45°, als ununterbrochene Schicht zugeführt und durch das in entsprechender Breite ausgeführte keilförmige Messer 3 gespalten. Hierauf werden die beiden Stengelhälften zwischen den umlaufenden Walzenpaaren 4, 4 bzw. 4, 4 kräftig gequetscht und dadurch gleichzeitig über das Messer weitergezogen. Die Wurzelenden der Stengelhälften werden nun durch Führungsmittel, wie Schienen oder Bänder, um eine Rolle 5 bzw. 5' herumgebogen. Neben dieser Rolle sind Fördermittel 6 bzw. 6' in Form endloser Bänder o. dgl. angeordnet, die die Rindenbänder 7 bzw. 7' erfassen und straft über die Rolle ziehen. Dabei heben sich die durch das Quetschen bereits weitgehend gelösten Holzbänder 8 bzw, 8' von der Rinde ab. An der der Rolle gegenüberliegenden Seite der Bastbänder greift ein Trennmesser 9 bzw. 9' mit entgegen dem Bandvorschub gerichteter Schneide an den Bändern an.The device according to the invention is shown schematically in the drawing shown. The stalks with the root ends are in front of the infeed rollers 2, 2 'in an inclined position, for example at 45 °, supplied as an uninterrupted layer and split by the wedge-shaped knife 3 designed with the appropriate width. The two halves of the stalk are then placed between the rotating pairs of rollers 4, 4 or 4, 4 vigorously squeezed and thereby pulled further over the knife at the same time. The root ends of the stem halves are now guided by guide means, such as rails or ribbons, bent around a roll 5 or 5 '. In addition to this role are subsidies 6 or 6 'in the form of endless bands or the like. Arranged, which the bark bands 7 or 7 'and pull it over the roll. The squeezing lifts them up Already largely loosened wooden strips 8 or 8 'from the bark. On the role opposite side of the bast strips engages a cutting knife 9 or 9 'with opposite the cutting edge aligned with the belt feed on the belts.
