Abstract

The subject of the invention is delivery rollers which grasp slivers and lead them on. On some spinning machines, textile fibres are processed in the form of slivers. When they run through delivery rollers, such slivers are inevitably pressed wide. This is undesirable in many cases. It has an adverse effect during the pressing and thickness measurement of the slivers. To prevent the fibre masses from drifting apart during their run through pairs of rollers, it is proposed to provide delivery rollers, especially autolevelling toothed rollers, with fine track grooves on their running surfaces. These provide a continuous grooving in which some of the fibres are guided. The sliver thereby gains a lateral hold and is led on in a constant width. <IMAGE>

Description

PATENTBESCHR Ei BUNGPATENT DESCRIPTION

===================== Lieferwalzen, die Faserbdnder kompakt erfassen und weiterfuhren Bei herkUmmlichen Lieferwalzen, wie z.B. Abzugs-, Press- und Tastwalzen, gleich ob sie glatt oder gezahnt sind, werden die durchlaufenden Faserbdnder durch den beaufschlagten Druck seitlich auseinandergedrückt und somit zwangslöufig breiter. Das ist in vielen Fällen unerwünscht und wirkt sich z.B. beim Pressen und Dickenmessen von Faserbändern nachteilig aus. Selbst bei einer genauen Zufuhrung des Faserbandes mittels einer Einlaufdüse, läßt sich das seitliche Auseinanderdriften der Fasermassen nicht vermeiden.===================== Delivery rollers that grip fiber slivers compactly and continue with conventional delivery rollers, such as take-off, press and feeler rollers, regardless of whether they are smooth or serrated, the fiber strands passing through will pass through the applied pressure is pushed apart laterally and therefore inevitably wider. This is undesirable in many cases and affects e.g. pressing and thickness measurement of slivers is disadvantageous. Even with a precise feed of the sliver by means of an inlet nozzle, the lateral drifting apart of the fiber masses do not avoid.

Es sind Bund- und Nutenwalzen bekannt, bei denen die Faserbander durch den umlaufenden Bund der einen Walze, in eine umlaufende Nut der Gegenwalze gepreßt werden. Dadurch wird ein seitliches Ausbreiten der Fasermassen verhindert. Diese Art Walzen sind jedoch in der Herstellung recht aufwendig und neigen dazu, bei ungenauer Einstellung zueinander das durchlaufende Faserband zu beschädigen.There are coil and grooved rollers known in which the slivers through the circumferential collar of one roller, pressed into a circumferential groove of the counter roller will. This prevents the fiber masses from spreading to the side. These Art rollers are, however, quite complex to manufacture and tend to be less precise Adjustment to each other to damage the sliver passing through.

Es wird vorgeJchlagen, Lieferwalzen, insbesondere Regulier zahnwalzen, an ihren Laufflächen mit feinen Spurrillen zu versehen, die sich als eine umlaufende Riffelung darstellen. Dadurch, daß ein Teil der Fasern in Rillen gefuhrt wird, bekommt das Faserband seitlichen Halt. Das Auseinanderdriften der Fasermassen wird so auf einfache Weise verhindert.It is suggested that delivery rollers, in particular regulating toothed rollers, to provide fine ruts on their running surfaces, which represent as a circumferential corrugation. By having some of the fibers in grooves is guided, the sliver gets a lateral hold. The drifting apart of the Fiber masses are prevented in a simple way.

Abb. 2 zeigt eine Regulierwalze, deren Zahnköpfe quer zum Zahn geriffelt sind.Fig. 2 shows a regulating roller, the tooth tips of which are corrugated transversely to the tooth are.
