In start-spinning a thread, which has to be performed after a condition in which the entire machine has been stopped or after a thread break, the individual working conditions have to be maintained as precisely as possible in order to keep the start-spinning points produced at the same spinning point and at different spinning points as uniform as possible and in order to ensure that they are of sufficient strength. An important criterion in this connection is the size and thickness of the ring of fibers located in the spinning rotor, on which the end of the thread is placed after it has been returned and from which the end of the thread is then drawn off again. This ring of fibers significantly influences the appearance and quality of the start-spinning point of the thread. In order to provide a situation in which it makes no difference whether start-spinning is performed after a brief standstill period or after an extended stand-still period, the silver feed of the spinning unit is switched on briefly prior to the actual start-spinning operation, while the rotor is still stopped. This ensures that the fiber tuft, which extends into the area of the opening means, is the same prior to every start-spinning operation, irrespective of the period of time during which the respective spinning point was stopped.
