Description

Die Erfindung richtet sich auf eine Lösung der Aufgabe, die Stengel von Nesselpflanzen durch Entblättern für die Gewinnung der Bastfasern vorzubereiten. Das Entblättern von Hand ist nicht nur zeitraubend, sondern wegen der den Blättern anhaftenden Brennhaare mit Schwierigkeiten verbunden. Die Eigenart der Erfindung besteht darin, daß man die Stengel senkrecht zu ihrer Längsrichtung durch Walzen laufen läßt, die die Blätter mit ihren Stielen bei dem Durchtritt abknicken. Hierbei ist ein starker Druck zwischen den Walzen zu vermeiden, weil sonst die Hülle leidet, aus der die Bastfasern gewonnen werden.The invention is directed to a solution to the problem, the stems of nettle plants to prepare for the extraction of the bast fibers by defoliation. The defoliation by hand is not only time consuming, but also because of the stinging hairs adhering to the leaves associated with difficulties. The peculiarity of the invention is that the stalk is perpendicular to its longitudinal direction runs through rollers that bend the leaves with their stalks at the passage. There is a lot of pressure here to be avoided between the rollers, because otherwise the shell from which the bast fibers are made suffers be won.

Auf der Zeichnung ist eine Vorrichtung zur Ausführung des Verfahrens beispielsweise veranschaulicht; es zeigen:In the drawing, an apparatus for carrying out the method is for example illustrates; show it:

Fig. ι Seitenansicht,Fig. Ι side view,

Fig. 2 Oberansicht mit teilweisem Schnitt, Fig. 3 Vorderansicht der Einrichtung.
In einem Gestell α sind wagerecht nebeneinander die beiden Kegelwalzen b, c federnd gelagert, so daß sie nur mit einem bestimmten mäßigen Druck auf .die zwischen ihnen durchlaufenden Stengel zu wirken vermögen. Diese Stengel werden quer zu ihrer Längsrichtung durch die Walzen geschickt, wobei sie sich durch einen Trichter d oder durch eine Laufbahn aus Tuch ο. dgl. zuführen lassen. *
FIG. 2 is a top view with partial section, FIG. 3 is a front view of the device.
In a frame α , the two tapered rollers b, c are resiliently mounted horizontally next to one another, so that they are only able to act on the stalks passing through between them with a certain moderate pressure. These stalks are sent transversely to their longitudinal direction through the rollers, where they are fed through a funnel d or through a track made of cloth ο. Like. Let feed. *

Die Walzen können einen Bürstenbelag erhalten, eine glatte Umfläche besitzen oder auch eine Riffelung erhalten, die beliebig gerichtet sein kann.The rollers can be given a brush coating, have a smooth surface or also receive a corrugation that can be directed in any direction.

Ferner können die Walzen kegelförmig oder zylindrisch gestaltet sein.Furthermore, the rollers can be conical or be cylindrical.
