PATENTAMT.PATENT OFFICE.
Bei Nadelstab- o. dgl. Strecken wird die obere Abzugwalze gewöhnlich durch Reibung von dem über die Unterwalze laufenden Ledertuch mitgenommen. Das Leder wird hierbei stark in Anspruch genommen, und es kommt bisweilen vor, daß die obere Walze gleitet, wodurch eine rasche Abnutzung des Ledertuches herbeigeführt und eine unregelmäßige Streckung des Faserbandes verursachtIn the case of needle bar or the like stretching, the upper take-off roller is usually driven by friction taken along by the leather cloth running over the lower roller. The leather is heavily used here, and it Occasionally, the upper roller slides, causing the Leather cloth brought about and caused an irregular stretching of the sliver
ίο wird. Diese Mißstände machen sich noch mehr bemerkbar bei Walzen von kleinem Durchmesser, die mehr und mehr in Gebrauch kommen, da man immer mehr danach strebt, möglichst kurze Fasern zu verarbeiten.ίο will. These shortcomings are even more noticeable in the case of small rollers Diameters that are coming into use more and more as one strives more and more to to process fibers that are as short as possible.
Man hat diesen Ubelständen bereits dadurch abzuhelfen gesucht, daß man die Zapfen der Oberwalze in Hülsen lagerte, die einen Antrieb von der Unterwalze aus in der Umlaufsrichtung der Oberwalze erhielten, so daß die Zapfenreibung der Oberwalze vermindert wurde und eine entsprechend kleinere Reibungskraft zwischen Oberwalze und der Unterwalze bezw. dem Ledertuch genügte, um die Mitnahme der ersteren durch die bezw. das letztere zu bewirken. Die Inanspruchnahme des Ledertuches ist dadurch zwar vermindert, aber nicht beseitigt, und selbstverständlich ist auch ein Gleiten durch Zurückbleiben der Oberwalze gegen die Unterwalze nicht ausgeschlossen.One has already sought to remedy these evils by the Spigots of the upper roller are stored in sleeves that have a drive from the lower roller in the Direction of rotation of the top roller received, so that the pin friction of the top roller is reduced was and a correspondingly smaller frictional force between the top roller and the bottom roller BEZW. the leather cloth was enough to take the former through the respectively. to effect the latter. The availment of the leather cloth is reduced, but not eliminated, and of course there is also a sliding through The possibility of the top roller remaining behind against the bottom roller cannot be ruled out.
Gemäß vorliegender Erfindung werden die erwähnten Übelstände vollkommen dadurch beseitigt, daß die Oberwalze ebenso wie die Unterwalze zwangläufig angetrieben wird.According to the present invention, the aforementioned inconveniences are completely eliminated eliminates the fact that the upper roller is forcibly driven as well as the lower roller.
Bei dem in der Zeichnung dargestellten Beispiel erfolgt der Antrieb der Oberwalze a von der Achse der Unterwalze b aus mittels des Zahntriebes c. In the example shown in the drawing, the upper roller a is driven from the axis of the lower roller b by means of the gear drive c.
Ein Gleiten der Oberwalze ist hierbei ausgeschlossen und außerdem wird das Ledertuch sehr geschont und erhält eine längere Dauer.A sliding of the top roller is excluded and the leather cloth is also removed very spared and has a longer duration.
