ABSTRACT:
An open-end spinning apparatus includes a feed device for supplying sliver; a device downstream of the feed device for separating the sliver into individual fibers; a fiber guide channel downstream of the fiber separating device for pneumatically transferring the individual fibers; a spinning rotor downstream of the fiber guide channel for rotating in a given direction and receiving the individual fibers, the spinning rotor having a fiber slide wall with a given radius of curvature; and a lid closing the spinning rotor and having a centrally disposed yarn draw-off tube and a lid extension. The fiber guide channel has an end region extending in the lid extension and being curved in the given direction. The end region has an orifice region disposed in the lid extension. The orifice region is a curved channel segment being closed on all sides and terminating in a small orifice, and the orifice region has a radius of curvature being matched to the given radius of curvature.
