Description

Riffelzylinder für Streckwerke. Bisher werden die stählernen Riffelzylinder der Streckwerke von Spinnmaschinen bekanntlich aus einem Stück erzeugt. Abgenutzte Riffelzylinder dieser Art müssen weggeworfen werden, da die Riffelung in der Regel nicht nachgeschliffen werden kann. Gemäß der vorliegenden Erfindung ist die Riffelung an besonderen Rohrstücken vorgesehen, die auf einen glatten Zylinderkörper aufgesetzt und mit diesem verbunden werden. Diese Art der Herstellung ermöglicht nicht nur die Auswechslung der geriffelten Rohrstücke, sondern auch die Wiederverwendung abgenutzter, aus einem Stück hergestellter Riffelwalzen.Corrugated cylinder for drafting systems. So far, the steel corrugated cylinders the drafting systems of spinning machines are known to be produced from one piece. Worn Corrugated cylinders of this type must be thrown away because the corrugation is usually cannot be reground. In accordance with the present invention, the corrugation is provided on special pipe sections that are placed on a smooth cylinder body and be connected to it. This type of manufacture not only enables the replacement of the corrugated pipe sections, but also the reuse of worn ones, corrugated rollers made from one piece.

Die Abb. i der Zeichnung zeigt einen Teil der üblichen Riffelwalzen; die Abb.2 und 3 zeigen in Ansicht und zum Teil im Schnitt der Erfindung gemäß ausgebildete Riffelwalzen.Fig. I of the drawing shows part of the usual corrugated rollers; FIGS. 2 and 3 show a view and partly in section according to the invention Corrugated rollers.

Bei den bisherigen Streckwerken sind die geriffelten Zylinderteile a mit dem Walzenkörper b aus einem Stück hergestellt (Abb. i). Der Erfindung gemäß werden auf einen Zylinderkörper b geriffelte Rohrstücke c (Abb. 2) aufgeschoben und auf geeignete Weise fest verbunden, beispielsweise durch Aufziehen im warmen Zustande, durch eine Verkörnung d oder mittels Keiles und Nut. An Stelle mehrerer Rohrstücke c kann ein einziges Rohr f auf den Zylinderkörper a geschoben werden (Abb.3), auf welchem die glatten und geriffelten Teile miteinander abwechseln.In the previous drafting systems, the corrugated cylinder parts are a made in one piece with the roller body b (Fig. i). According to the invention corrugated pipe sections c (Fig. 2) are pushed onto a cylinder body b and firmly connected in a suitable manner, for example by pulling it up in a warm place Conditions by means of granulation d or by means of a wedge and groove. Instead of several Pipe sections c, a single pipe f can be pushed onto the cylinder body a (Fig.3), on which the smooth and corrugated parts alternate with each other.

Die Erfindung ist insbesondere beim Umbau gewöhnlicher Streckwerke in Durchzugsstrecke nach C a s a b 1 a n c a von Vorteil. Bei den letzteren müssen bekanntlich an Stelle stumpf geriffelter Streckzylinder scharf geriffelte verwendet werden. Die Riffelzylinder der gewöhnlichen Streckwerke werden auf Schleifmaschinen glatt abgeschliffen und entsprechend den Abb.2 und 3 mit scharf geriffelten Rohrstücken versehen. Auf diese Weise können die Kosten des Umbaues bedeutend herabgesetzt werden.The invention is particularly useful when converting conventional drafting systems in the passage to C a s a b 1 a n c a advantageous. The latter must as is well known, sharply corrugated cylinders are used instead of blunt corrugated stretching cylinders will. The corrugated cylinders of the usual drafting systems are made on grinding machines Sanded smooth and according to Figures 2 and 3 with sharp corrugated pipe pieces Mistake. In this way, the cost of the conversion can be significantly reduced.
