PATENTAMT.PATENT OFFICE.
Bei Heilmann'schen Kämmmaschinen hat man Abreifswalzen mit gekrümmter und geriffelter Oberfläche benutzt, bei welchen die Krümmung und Riffelung der Oberfläche dem Zweck dienen sollte, die Fasern sowohl in der Mitte als auch an den Enden mit Sicherheit zu fassen, indem die Walzen infolge der eigenartigen Beanspruchung sich derart durchbiegen, dafs sie an der Klemmstelle eine gerade Be-. rührungslinie bilden. Die bisher bekannten Walzen dieser Art haben sich jedoch nicht vollkommen bewährt. Die Rillen wurden in der Weise hergestellt, dafs das Schneidwerkzeug parallel zur Walzenmittellinie bewegt wurde. Beim Ausbiegen der Walze ergiebt sich dann, dafs die Rillenböden; in der Mitte weiter von der Klemmlinie entfernt sind als an den Enden der Walzen, so dafs die Fasern nicht gleichmäfsig gefafst werden.In Heilmann's combing machines, pick-up rollers with a curved and corrugated surface were used, in which the curvature and corrugation of the surface should serve the purpose of gripping the fibers both in the middle and at the ends with certainty, by pulling the rollers as a result of the peculiar Stress to bend in such a way that they have a straight load at the clamping point. form contact line. However, the previously known rollers of this type have not fully proven themselves. The grooves were made by moving the cutting tool parallel to the roll center line. When the roller is bent out, it is found that the groove bottoms ; are further away from the nipping line in the middle than at the ends of the rollers, so that the fibers are not evenly grasped.
Um diesem Uebelstande abzuhelfen, werden Riffeln in der Weise hergestellt, dafs sie auf der ganzen Walzenlänge gleichmäfsige Tiefe erhalten.In order to remedy this inconvenience, corrugations are made in such a way that they open up Maintain a uniform depth over the entire length of the roller.
Fig. ι der Zeichnung zeigt ein Walzenpaar im Längsschnitt im unbelasteten Zustande, Fig. 2 zeigt die Einrichtung in Ansicht im Arbeitszustand und Fig. 3 im Querschnitt.Fig. Ι of the drawing shows a pair of rollers in longitudinal section in the unloaded state, Fig. 2 shows the device in a view in the working state and Fig. 3 in cross section.
Die untere Walze α des Walzenpaares a b, zwischen welchem das Laufleder c durchgeführt wird, ist bei der als Beispiel dargestellten Ausführungsform in festen Gestelltheilen gelagert, während die obere Walze b derart gelagert ist, dafs von oben ein Druck auf die Lagerzapfen e ausgeübt werden kann, welcher auf die Walze b selbst übertragen wird. Die Lagerschalen werden zweckmäfsig kugelförmig oder quer zur Drehmittellinie cylindrisch gestaltet, um den Durchbiegungen der Walzen Rechnung zu tragen. Die in die Walzen eingeschnittenen Rinnen haben durchweg gleiche Tiefe. Sie werden mit Hülfe einer besonderen Riffelhobelmaschine hergestellt, da das Schneidmesser bei Herstellung der Rinne eine bogenförmige oder paraboloidische Bahn durchschreiten mufs und sorgfältig vermieden werden mufs, dafs die Rille in der Mitte der Walze tiefer ist als an den Enden.The lower roller α of the roller pair ab, between which the running leather c is passed, is mounted in fixed frame parts in the embodiment shown as an example, while the upper roller b is mounted in such a way that pressure can be exerted on the bearing journals e from above, which is transferred to the roller b itself. The bearing shells are expediently designed spherically or cylindrically transversely to the center line of rotation in order to take account of the deflection of the rollers. The grooves cut into the rollers are all of the same depth. They are made with the aid of a special fluted planer, since the cutting knife must traverse an arcuate or paraboloidal path when making the groove, and care must be taken to avoid that the groove is deeper in the middle of the roller than at the ends.
Zweckmäfsig werden die Rillen schraubenförmig um die Walze geführt (Fig. 2), wodurch der beständig auf der oberen Walze lastende Druck nicht stofsweise auf deren ganzer Länge auf die zwischen beiden Walzen befindlichen Fasern übertragen wird, sondern fortlaufend in beständig sich verschiebenden Punkten. Der Antrieb erfolgt durch ein auf einem Zapfen der unteren Walze sitzendes Zahnrad g, welches mit einem geeigneten Trieb in Eingriff steht. Die obere Walze wird von der unteren mitgenommen. Der Antrieb kann auch in beliebiger anderer geeigneter Weise vermittelt werden.The grooves are expediently guided helically around the roller (Fig. 2), whereby the constant pressure on the upper roller is not transferred in substance over its entire length to the fibers located between the two rollers, but continuously in constantly shifting points. It is driven by a toothed wheel g which is seated on a pin of the lower roller and which meshes with a suitable drive. The upper roller is taken along by the lower one. The drive can also be conveyed in any other suitable manner.
