ABSTRACT:
An apparatus for start-spinning a thread is arranged movably relative to each individual spinning unit along an open-end spinning machine in order to be able to perform start-spinning operations there if required. In order to avoid having to start spinning at the generally very high operating speeds of the spinning rotors, because the start-spinning operation would be made more difficult by these high speeds, in accordance with the invention the spinning rotor runs up to speed from a standstill during the start-spinning operation after a brake has been released, so that spinning is started during a period in which the spinning rotor has not yet achieved its operating speed. The start-spinning speed is therefore clearly lower than the operating speed of the spinning rotor.
