Open-end friction spinning machine

摘要

An open-end friction spinning machine is provided having a plurality of spinning units arranged next to one another. A suction device assigned to each spinning unit which acts in the area of the yarn formation zone may be selectively switched off such as in the case of a yarn breakage. So that the air throughput balance does not change in the area of the other spinning units when the suction device of a single unit is switched off, devices are provided for maintaining the air throughput relatively constant. Air throughput normally used by the suction devices in the yarn forming area of the spinning unit is diverted, for cleaning and maintenance purposes.
