    摘要: In a spinning position of a spinning machine a longitudinal fibre array first is refined in a drafting process, and the refined fibre array then is subject to a twist imparting process, and is taken off the twist-imparting zone as a yarn. In case of an interruption of the spinning process, the intake into the refinement zone is stopped before the delivery from the refining zone is stopped in such a manner that the longitudinal fibre array is severed between the intake and the delivery zones forming a free front end zone. The free end of the yarn, generated by the interruption of the spinning process, is treated in such a manner that a yarn end zone is tapered and is positioned upstream from the twist imparting zone. When the spinning process is resumed, the movements of the yarn end zone and of the fibre array front end zone for imparting twist are coordinated in time sequence in such a manner that these two zones overlap as they are subject to the twist imparting process. Furthermore owing to the controlled reduction in draft, adapted to the taper of the yarn end zone, a gradually increasing fibre mass is generated in the fibre array front end zone, which can be very exactly adapted to the taper of the yarn end zone.

The apparatus substantially comprises a fiber and thread guide means using a fiber guide conduit with a fiber guide surface for guiding fibers and a thread guide for guiding at least one continuous yarn into an inlet orifice of a yarn guide conduit and a fluid delivery device for producing a swirl flow about the inlet orifice of the yarn guide conduit so that the at least one continuous yarn can be spun over by the fibers. The thread guide is either a groove which is associated with the fiber guide surface, a bore disposed below the fiber guide surface, an individual tube-like element, or a tube-like element that is combined with a groove or a bore. The thread guide is introduced in a fiber and thread guide means, with the axis of the groove, the bore or the tube-like element being in alignment with the axis of the yarn guide conduit.
