Abstract
The invention relates to an open-end spinning device with a rotor housing connected to a source of suction and open at a front side, in which a rotor rotates at relatively high rpm. A cover element is provided for closing the rotor housing and a cover extension is affixed to the cover element as an exchangeable, dynamically balanced component. The cover extension is releasably disposed in a receptacle recessed in the cover element by means of mating inclined seating surfaces and by axially acting fasteners, and is exactly fixed in position inside this receptacle by an alignment pin engaged in aligned bores in the cover element and in the cover extension.
