Abstract
A yarn withdrawal navel for an open-end spinning apparatus is provided with a ferromagnetic locating surface. This is used for the purpose of coupling to a mounting, which has at least one permanent magnet. The yarn withdrawal navel and the mounting have abutment surfaces which are configured to vary the magnetic mounting effect on the navel as a function of the relative rotation position of the navel and the mounting.
