Open-end spinning unit.

摘要

An open-end spinning unit is provided which has a spinning rotor open on one side and a bottom wall and an inner wall. A closing element covers the open side of the rotor and includes a fiber supply duct. To enhance the air conveyance of fibers to the inner wall, at least one suction opening is provided downstream of an outlet opening of the fiber supply duct in the closing element so that an airstream directed from the outlet opening toward the suction opening is generated in the same direction as the direction of rotation of the rotor. This invention is applicable not only to a forced-exhaustion type of unit but also to a self-exhaustion type of unit.
