Yarn quality monitoring system.

摘要

A yarn spinning machine has a large number of spinning stations and two independently operable monitoring systems. One such system is responsive to the operating conditions of the stations ("spin/no spin") and can distinguish individual stations at a central data register (12, 14). The other is responsive to the quality of yarn produced at each station, but cannot distinguish individual stations at the central register. The yarn quality monitor can induce a yarn break at a station producing poor yarn. The monitoring systems are linked via a CPU, a quality defect register (20) and a yarn break register (12) to allocate quality induced breaks to individual operating stations.
