Abstract
A fiber guide channel for pneumatic transport of individual fibers combed from a sliver by an opening cylinder of an open end spinning device for delivery to a spinning rotor. The fiber guide channel is arranged in a cover element for the rotor housing and the input side of the fiber guide channel is matched in its width to the mountings of the opening cylinder. The inlet and the outlet openings of the fiber guide channel have a slot-like shape and the maximum extension (B) of the inlet opening extends parallel to the axis of the opening cylinder. The maximum extension (L) of the outlet opening of the fiber guide channel is rotated about an imaginary center line of the fiber guide channel by 90°±15° relative to the maximum extension (B) of the inlet opening. The fiber guide channel has a substantially cylindrical zone Z, between the inlet and outlet openings, with the cross-section of the fiber guide channel constantly decreasing from the inlet opening to the zone Z.
