Abstract
An open-end rotor spinning device comprising a spinning motor rotatable at high speed inside a rotor housing subjected to low pressure and closable by a covering element. A single motor-driven opening cylinder rotates in a opening cylinder housing. A fiber guiding channel () includes an output-side channel section extending in a channel plate adapter whose installation position in the covering element is specified by its position with regard to the spinning rotor, and an input-side channel section positioned inside the opening roller housing such that the center longitudinal axes of the channel sections are angled relative to one another. The operable spinning disposition of the input-side channel section () is selectively adjustable with regard to the output-side channel section () of the fiber guiding channel () to relatively displace their respective center longitudinal lines () by angles (α, β) to obtain optimal yarn-dynamic values.
