Abstract

Auflösewalzeneinheit eines Offenend-Spinnaggregats, die einen Auflösewalzenring mit einer Sägezahngarnitur besitzt, bei dessen Fertigung aus einer Hülse zunächst durch Materialabtrag wendelförmig umlaufende Nuten erzeugt wurden, zwischen denen Stege stehen geblieben sind, wobei aus anschließend quer zu den Stegen eingebrachte Einschnitten die Zahnform der Zähne ausgebildet ist. Der Auflösewalzenring ist an seinen Stirnseiten zum Schutz der Zahnung durch Ringbunde einfaßbar. Dabei ist mindestens ein Ringbund zusammen mit den Zähnen Bestandteil des Auflösewalzenringes, wobei die Zahnung in den Ringbund übergeht.Opening roller unit of an open-end spinning unit, the one Has opening roller ring with a saw tooth set, at its manufacture from a sleeve initially by material removal helical circumferential grooves were created between them Footbridges have remained, but then laterally across incisions made in the webs the tooth shape of the teeth is trained. The opening roller ring is on his End faces can be framed by ring collars to protect the teeth. There is at least one ring collar together with the teeth Part of the opening roller ring, the teeth in the Ringbund passes over.

Die erfindungsgemäße Auflösewalzeneinheit mindert den Herstellungs- und Montageaufwand und verbessert den Garnherstellungsprozeß.
