Abstract

In an open-end spinning unit having a spinning rotor presenting an entrance opening, a break-up roller mounted for rotation coaxially with the spinning rotor and having a frontal end section at the end thereof directed toward the spinning rotor, the frontal end section being generally enclosed by the portion of the spinning rotor defining its entrance opening, and a housing enclosing at least part of the break-up roller, there is further provided, in order to improve the guidance of fibers into the fiber collecting trough of the spinning rotor, a fiber collecting ring located between, and coaxial with, the spinning rotor and the break-up roller, and supported by the housing, the fiber collecting ring protruding axially, in the direction away from the spinning rotor, beyond the frontal end section of the break-up roller and, in the direction toward the spinning rotor, beyond the entrance opening of the spinning rotor, with the inner surface of the fiber collecting ring facing the break-up roller and serving at least partially as a fiber guiding surface.
