ABSTRACT:
In order to be able to start-spin on the individual spinning units of an open-end spinning machine under conditions which deviate from the operating conditions and which are, in particular, significantly more favorable for start-spinning, the end of the thread is placed on a ring of fibres located in the spinning rotor at a spinning rotor speed which is reduced relative to the operating speed. At the same time, the sliver feed is reduced in such a manner that the amount of sliver feed corresponds to the reduced speed of the spinning rotor. This reduced sliver speed is produced by a mobile start-spinning unit which is equipped with means which intervene in the drive and/or control of the drive or control means causing feed of the sliver.
