Method and apparatus for detecting the bobbin circumference of cross-wound bobbins and for utilizing the result

Apparatus for detecting and utilizing the bobbin circumference of cross-wound cylindrical or conical bobbins or cheeses in a textile machine producing the bobbins, comprising means for holding a bobbin, means for driving the bobbin, sensors detecting movement of said driving means and movement of the bobbin and producing signals;

• at least one winding station computer connected to said sensors including means for controlling a calculating for determining and evaluating the attained circumference of the bobbin from the signals and processing the signals for further evaluation;
• an overriding computer receiving a linkage program for a mathematical linkage of the signals processed by said winding station computer being cleansed of randomness of the current signal pickup and symbolizing the current bobbin circumference;
• a first operative connection connected between said winding station computer and said overriding computer;
• and a second operative connection connected between said winding station computer and said overriding computer for transmitting the linkage result to said winding station computer;
• said winding station computer having means for utilizing the linkage result for at least one purpose from the group consisting of displaying the linkage result, affecting the winding process in accordance with the linkage result, detecting the yarn length in accordance with the linkage result, and terminating the winding process in accordance with the linkage result.
