Description

Vorrichtung zur Untersuchung der Haarseite von Fellen, bei welcher ein Messer mit einem Blasrohr starr verbunden ist. Die Erfindung bezieht sich auf eine Vorrichtung zur Untersuchung der Haarseite von Fellen, bei welcher ein Messer mit einem 'Blasrohr starr aber lösbar verbunden ist.Device for examining the hair side of skins, in which a knife is rigidly connected to a blowpipe. The invention relates to a device for examining the hair side of skins, in which a knife is rigidly but detachably connected to a 'blowpipe.

Die Vorrichtung ist in Abb. r durch eine Ansicht und in Abb. z und 3 durch Schnitte dargestellt.The device is shown in Fig. R by a view and in Fig. Z and 3 represented by sections.

Ein Blasrohr 12 ist durch' Schellen S mit zwei Blechen B zu einem Ganzen starr verbunden. Ein Kürschnermesser M, das seine Schneide in der Kante d hat, kann zwischen die beiden Bleche B geschoben werden und durrch eine Schlaufe I( festgehalten werden. Die Zufuhr der Luft erfolgt durch einen Blasebalg oder einen Ventilator, und zwar in der Pfeilrichtung nach Abb. i.A blowpipe 12 is by 'clamps S with two plates B to one The whole thing rigidly connected. A skinning knife M, his Cutting edge in the edge d, can be pushed between the two sheets B and through a loop I (to be held in place. The air is supplied through a bellows or a fan, in the direction of the arrow according to Fig. i.

Es ist bereits eine Vorrichtung für den gleichen Zweck bekannt, bei der das Messer in dem Blasrohr angeordnet ist. Wie aus der Zeichnung ersichtlich, unterscheidet sich die Vorrichtung nach der Erfindung dadurch, daß das Messer M außerhalb des Rohres R und des ausströmenden Druckluftkegels und die Schneide d parallel der Achse dieses Druckluftkegels liegt.A device for the same purpose is already known at which the knife is arranged in the blowpipe. As can be seen from the drawing, the device according to the invention differs in that the knife M outside the tube R and the outflowing compressed air cone and the cutting edge d lies parallel to the axis of this compressed air cone.

Durch diese Anordnung werden der bekannten Vorrichtung gegenüber wesentliche neue Wirkungen erzielt. Bei ersterer vermag der Luftstrom ungeteilt und ohne Wirbelung auf das zu untersuchende Fell aufzutreffen. Durch Einsetzen eines mehr oder weniger weiten auch flachen Rohres R kann die jeweilig gewünschte Scheitelungsform erzielt werden. Bei der bekannten Vorrichtung befindet sich in dem Druckluftkegel ein Messer. Dieses teilt den Luftstrom in zwei Hälften, wodurch der Luftstrom senkrecht zu den Messerflanken verbreitert und schädliche Luftwirbelungen erzeugt werden. Hinter dem Messer tritt eine Verminderung der Luftgeschwindigkeit ein und daher auch ein Ausbreiten des Luftstromes. Die auftretenden Luftwirbelungen bewirken ein Hin- und Herflattern der Pelihaare. Alle diese Erscheinungen beeinflussen eine ordnungsmäßige Scheitelung der Pelzlhaare ungünstig.This arrangement makes the known device essential achieved new effects. With the former, the air flow is able to be undivided and without turbulence to hit the fur to be examined. By inserting one more or less A wide and flat tube R can achieve the desired crest shape will. In the known device there is a knife in the compressed air cone. This divides the airflow in half, making the airflow perpendicular to the Blade flanks are broadened and harmful air turbulence is generated. Behind the knife is subject to a reduction in air speed and therefore also occurs Spreading the air flow. The air turbulence that occurs causes a back and forth Fluttering peli hairs. All of these phenomena affect an orderly one Parting of the fur hair is unfavorable.

Durch die vorliegende Anordnung wird nicht nur wie bei der bekannten Vorrichtung ein Anzeichnen der kahlen Stellen im Haar, sondern durch das gute Gesichtsfeld auch ein unmittelbares Schneiden der Felle ermöglicht.The present arrangement is not only like the known one Device a marking of the bald spots in the hair, but through the good field of vision also enables the skins to be cut directly.

PATENTANSPRUCH: Vorrichtung zur Untersuchung der Haarseite von Fellen, bei welcher ein Messer mit einem Blasrohr starr verbunden ist, dadurch gekennzeichnet, daß das Messer (M) außerhalb des Blasrohres (R) derart angeordnet ist, daß es nicht im Druck-Luftkegel liegt, um schädliche Wirbelungen im Luftstrom außerhalb des Blasrohres (R) zu vermeiden. Claim: Device for examining the hair side of skins, in which a knife is rigidly connected to a blowpipe, characterized in that the knife (M) is arranged outside the blowpipe (R) in such a way that it is not in the pressure-air cone to avoid damaging eddies in the air flow outside the blowpipe (R).
