Description
Unterwalzen für Spinnmaschinenstreckwerke Die Erfindung betrifft eine Ausgangsunterwalze und Eingangsunterwalze eines Streckwerks für Spinnereimaschinen mit über dem Walzenumfang angeordneten, sieh in Längsrichtung erstreckenden Riffeln.Lower rollers for spinning machine drafting units The invention relates to a Exit bottom roll and entry bottom roll of a drafting system for spinning machines with longitudinally extending corrugations arranged over the roller circumference.
Es sind bereits Unter- oder Riffelwalzen mit unsymmetrisch profilierter Kannelierung bekanntgeworden. bei denen jedoch ein Unterriemchen um die betreffende Walze geschlungen war und das unsymmetrische Profil dazu diente, die Mitnahrne der auf dem Riemehen auflie-enden Oberwalze zu verbessern. Auch sind schon unsymmetrisch profilierte Riffelungen auf Durchzugswalzen vorgeschlagen worden, die mit je einem sich diesen anschmiegenden gleitenden Belastungskörper zusammenarbeiteten.Bottom or corrugated rolls with asymmetrically profiled fluting have already become known. In which, however, a lower apron was wrapped around the relevant roller and the asymmetrical profile served to improve the drag of the upper roller resting on the belt. Asymmetrically profiled corrugations on pull-through rollers have also already been proposed, each of which cooperates with a sliding load body that nestles against it.
Der Erfindung liegt die Aufgabe zugrunde, den Walzengriff auf das Faserband zu verbessern, ohne die Oberwalzenbelastung über Gebühr zu erhöhen.The invention is based on the object of the roller handle on the Improve sliver without unduly increasing the load on the top rollers.
Die Erfindung besteht darin, daß die Flanken der Riffeln der Ausgangs- oder Eingangsunterwalze entgegen dem Verzugswiderstand, d. h. in Richtung der die Lunte verziehenden Kraft, von der radial symmetrischen Anordnung abweichend gegenüb#er den Radien in einem Winkel angestellt sind.The invention consists in that the flanks of the corrugations of the output or input lower roller counter to the draft resistance, d. H. in the direction of the force pulling the fuse, deviating from the radially symmetrical arrangement with respect to the radii are employed at an angle.
Hierdurch wird der Walzengriff an den Klemmstellen wesentlich verbessert, wie praktische Versuche erwiesen haben.This significantly improves the roller grip at the clamping points, as practical tests have shown.
Ein Ausführungsbeispiel nach der Erfindung ist in den Zeichnungen wiedergegeben. Es zeigt Fig. 1 die Verzugsstrecke eines Streckwerkes und Fig. 2 die Riffelung der Ausgangsunterwalze der in Fig. 1 gezeigten Verzugsstrecke in vergrößerter Dar-Stellung.An embodiment according to the invention is shown in the drawings. 1 shows the drafting section of a drafting system and FIG. 2 shows the corrugation of the lower exit roll of the drafting section shown in FIG. 1 in an enlarged representation.
Das schnellaufende Ausgangswalzenpaar 1, 2 bildet mit dem langsamer laufendenEingangswalzenpaar 3, 4 je eine Klemmstelle, welche die Verzugszone eines Streckwerkes begrenzen. Die Unterwalzen 2 und 4 sind mit einer unsymmetrischen Riffelung versehen.The high-speed pair of output rollers 1, 2 and the slow- speed pair of input rollers 3, 4 each form a clamping point which delimits the draft zone of a drafting system. The lower rollers 2 and 4 are provided with an asymmetrical corrugation.
In Fig. 2 ist die Klemmstelle zwischen den Walzen 1 und 2 vergrößert dargestellt. Durch die inneren Kanten 5 und 6 einer einzelnen Kannele 7 sind zwei radial gerichtete Strahlen S und S' gelegt. DieFlanken 8 und 9 der die Kanntele 7 bildenden Zähne sind gegenüber den Strahlen S und S' um Winkel a und ß geneigt, wobei im Gegensatz zu bisher der Winkel a größer ist als der Winkel ß. Dadurch ergibt sich eine mit »Anstellung« bezeichnete, im Drehsinn der Walze vorgebeugte unsymmetrische Stellung der Riffelzähne. Im Falle der Eingangsunterwalze 4 muß, wie Fig. 1 zeigt, die Anstellung in einer dem Drehsinn entgegengesetzten Richtung erfolgen, damit sie wiederum der Wirkungsrichtung der Verzugskraft im Streckfeld entgegensteht.In Fig. 2, the nip between the rollers 1 and 2 is shown enlarged. Two radially directed beams S and S 'are laid through the inner edges 5 and 6 of a single flute 7. The flanks 8 and 9 of the teeth forming the Kanntele 7 are inclined with respect to the rays S and S ' by angles α and β , the angle α being greater than the angle β in contrast to previously. This results in an unsymmetrical position of the corrugated teeth, which is referred to as "adjustment" and is bent forward in the direction of rotation of the roller. In the case of the lower input roller 4, as FIG. 1 shows, the adjustment must take place in a direction opposite to the direction of rotation, so that it again opposes the direction of action of the draft force in the stretching field.
