Abstract

Die Erfindung betrifft eine Offenend-Spinneinrichtung umfassend ein mit Unterdruck beaufschlagbares Rotorgehäuse (1) und einen Spinnrotor (2), das Rotorgehäuse (1) ist nach vorne hin offen und durch ein Deckelelement verschließbar, nach hinten weist das Rotorgehäuse (1) eine Rückwand (3) mit einer Durchtrittsöffnung (4) für einen Rotorschaft (5) des Spinnrotors (2) auf. Um das Auftreten von Fadenwickeln im Inneren des Rotorgehäuses (1) hinter dem Spinnrotor zu verhindern, ist vorgesehen, dass am größten Außendurchmesser des Spinnrotors (2) ein enger Spalt (6) von weniger als 2mm Spaltbreite zwischen dem Spinnrotor (2) und der Rückwand (3) des Rotorgehäuses (1) vorhanden ist und dass die Rückwand (3) des Rotorgehäuses (1) so ausgebildet ist, dass im Inneren des Rotorgehäuses (1) der Bereich (7) hinter dem Spinnrotor (2) verdeckt wird.

Figure imgaf001
The invention relates to an open-end spinning device comprising a rotor housing (1) which can be subjected to negative pressure and a spinning rotor (2), the rotor housing (1) being open towards the front and closable by a cover element, the rotor housing (1) facing backwards ( 3) with a passage opening (4) for a rotor shaft (5) of the spinning rotor (2). In order to prevent the occurrence of filament winding inside the rotor housing (1) behind the spinning rotor, it is provided that at the largest outer diameter of the spinning rotor (2) has a narrow gap (6) of less than 2mm gap width between the spinning rotor (2) and the rear wall (3) of the rotor housing (1) is present and that the rear wall (3) of the rotor housing (1) is formed so that in the interior of the rotor housing (1) the area (7) behind the spinning rotor (2) is covered.
