摘要：
A friction spinning unit of a multi-position friction spinning machine includes a pressure tapping 5 in the suction line 4 to a suction port 8 in the fibre feed duct 2. A suction transducer 6 responsive to the suction in the tapping 5 controls the fibre feed clutch 7 of that particular friction spinning unit for disengaging the friction spinning unit when suction value sensed by the transducer 6 deviates from a predetermined range of acceptable suction values, to shut-down the friction spinning unit well before the yarn quality has been impaired to a sufficient extent to cause a yarn break.
