ABSTRACT:
A channel plate for an open-end rotor spinning device for closing a rotor housing charged with underpressure in which a spinning rotor rotates, having a channel plate tower extending into the spinning rotor, in whose shell face the outlet opening of a fiber guide channel is arranged and in whose front side a yarn draw-off nozzle can be fixed. A concavely arched transition surface adjoins a cylindrical part of the shell face, and the channel plate tower has a diameter at the height of the rotor edge of the spinning rotor such that an annular gap of maximally 2 mm width between the spinning rotor and the channel plate tower results during spinning. At most one half of the outlet opening of the fiber guide channel is arranged in the area of the cylindrical shell face, and the remaining part in the arched transition surface. The wall area of the outlet opening remotest from the front side is at a distance to the center longitudinal axis of the channel plate at least 0.5 to 3 mm greater than the distance of the adjoining wall area in respect to the center longitudinal axis.
