Abstract: A friction spinning unit of a multi-position friction spinning machine includes a pressure tapping in the suction line to a suction port in the fibre feed duct. A suction transducer responsive to the suction in the tapping controls the fibre feed clutch of that particular friction spinning unit for disengaging the friction spinning unit when suction value sensed by the transducer 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.
