Abstract

Open-end spinning machine apparatus is provided which includes a yarn measuring device at each of the individual spinning units for determining the transverse dimension of the running yarn produced at the spinning units. In addition, intermediate storage means are provided for electronically storing yarn measurement data at each of the individual spinning units. In order to process the yarn measurement data, a process computer is provided at a mobile servicing instrument which is selectively movable to respective servicing positions at the spinning units. The process computer and mobile servicing instrument also includes means for carrying out servicing operations at the respective spinning units in the event of detected yarn flaws or the like. By providing the process computer at the mobile servicing unit, with individual separate intermediate storage systems at each spinning unit, the total cost for electronic equipment is substantially minimized while obtaining all of the advantages of a complete computerized analysis system. According to certain preferred embodiments the circuitry at the individual spinning units is designed to store data as to periodic yarn defects leading to …
