1. Open-end rotor spinning device comprising a spinning rotor, which rotates during the spinning process at a high speed in a rotor housing, which can be subjected to low pressure and which can be closed by a covering element, comprising a single motor-driven opening cylinder, which rotates in an opening cylinder housing, and also comprising an at least two-part fiber guiding channel, wherein the output-side channel section of the fiber guiding channel extends in a channel plate adapter, the center longitudinal axis of which extends coaxially to the axis of rotation of the spinning rotor, and the input-side channel section of the fiber guiding channel is positioned in the opening cylinder housing in such a way that the center longitudinal axes of the channel sections are arranged inclined with respect to one another, characterized in that the input-side channel section (30) of the fiber guiding channel (18) is mounted so as to be selectively movable to a limited extent with respect to the output-side channel section (31) of the fiber guiding channel (18) for adjustable setting of an operating disposition of the input-side channel section (30) angularly relative to the output-side channel section (31) when the covering element is closed on the rotor housing for performing the spinning process, said adjustable setting of the operating disposition of the input-side channel section (30) causing the center longitudinal line (32) of the input-side channel section (30) to be selectively displaceably arranged with respect to the center longitudinal line (33) of the output-side channel section (31) by angles (α, β) to achieve optimal yarn-dynamic values.
