ABSTRACT:
A method for monitoring the operation of a multiposition spinning machine wherein filaments are extruded from a spinning pack at each position and advanced as a yarn bundle in a path, then split at a location into a plurality of threadlines to be forwarded to a plurality of windups to be wound on packages and scheduling events at predetermined times in the preparation of said packages with the aid of a digital computer, the method relies on a program with a knowledge database that includes the operative state of each position, the elapsed time since the initiation of each package, predetermined event times unique to the filaments being wound, the positional configuration of said machine, a hueristic rule base. The operative state of each position is sensed by monitoring the presence or absence of the advancing yarn bundle and threadlines as a function of time and this information is provided to the computer which compares the operative state of each position and the elapsed time since initiation of each package and indicates that the time for performing said events has been reached.
