Abstract
Abstract A method of manufacturing textile coils having a predetermined thread length in a textile machine having a plurality of individual work stations operating at a predetermined speed, which includes establishing a given value for the working time of each individual work station from a predetermined thread length and working speed, continuously measuring the shutdown time of each individual work station, adding the shutdown time to the working time to provide a total operating time, and stopping the respective work station when the nominal value of the total operating time is reached; and apparatus for carrying out the foregoing method.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
187 words
Apparatus for manufacturing textile coils having a predetermined thread length in a textile machine having a plurality of individual winding stations, comprising means for establishing and storing a nominal value for the winding time of each individual winding station, means for continuously measuring the shutdown time of each winding station, means for adding the shutdown time to the winding time of each said station to provide a total operating time, and means for stopping the respective winding station when the nominal value of total operating time is reached, said means for establishing and storing a nominal value for the winding time including a plurality of storage elements arranged in accordance with the location of each winding station, said means for measuring the shutdown time including switching means providing a signal indicating the shutdown of said winding station and clock means providing timing pulses for starting an interrogation cycle for determining the shutdown time of each individual winding station, said means for stopping the respective winding station including means for sequentially addressing each winding station and means for detecting when said value of total operating time is reached.
Claim 2
Dependent Claim
187 words
Apparatus for manufacturing textile coils having a predetermined thread length in a textile machine having a plurality of individual winding stations, comprising means for establishing and storing a nominal value for the winding time of each individual winding station, means for continuously measuring the shutdown time of each winding station, means for adding the shutdown time to the winding time of each said station to provide a total operating time, and means for stopping the respective winding station when the nominal value of total operating time is reached, said means for establishing and storing a nominal value for the winding time including a plurality of storage elements arranged in accordance with the location of each winding station, said means for measuring the shutdown time including switching means providing a signal indicating the shutdown of said winding station and clock means providing timing pulses for starting an interrogation cycle for determining the shutdown time of each individual winding station, said means for stopping the respective winding station including means for sequentially addressing each winding station and means for detecting when said value of total operating time is reached.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1 wherein said means for stopping said winding station includes a relay.
Claim 4
Dependent Claim
12 words
The apparatus of claim 1 wherein said addressing means is a multiplexer.
Claim 5
Dependent Claim
26 words
The apparatus of claim 3 wherein the number of line conductors between said multiplexer and said winding stations is less than the number of winding stations.
Claim 6
Dependent Claim
58 words
The apparatus of claim 3 including means for restarting a winding station after it has been stopped because the pretermined thread length had been attained, and means for determining and correcting the nominal value for the working time of the respective work station, said restarting means being actuatable only upon simultaneous actuation of said determining and correcting means.
