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.
摘要翻译： 在纺丝机的旋转位置，首先在牵伸过程中精制纵向纤维阵列，然后将精制纤维阵列进行扭曲赋予过程，并且作为纱线从扭曲赋予区域脱去。 在纺丝过程中断的情况下，在从精炼区域的输送停止之前停止进入精制区域的进料，使得纵向纤维阵列在进料口和输送区域之间切断，形成自由前端 区。 通过纺丝工序的中断而产生的纱线的自由端以纱线端部区域为锥形并位于扭曲赋予区域的上游的方式进行处理。 当纺丝过程恢复时，纱线端部区域和用于赋予捻度的纤维阵列前端区域的运动以时间顺序协调，使得这两个区域在进行扭转赋予过程时重叠。 此外，由于可以控制的吃水深度减小，适应于纱线端部区域的锥度，在纤维阵列前端区域中产生逐渐增加的纤维质量，其可以非常精确地适应于纱线端部区域的锥度。
