Abstract
A method and apparatus for detecting and utilizing the bobbin circumference of cross-wound bobbins or cheeses in a textile machine producing the bobbins includes determining and evaluating the attained circumference of the cheese from measured values produced by sensors detecting the growth of the cheese. The measured values are continuously detected and processed and optionally stored in memory in at least one computer for further evaluation. A mathematical linkage symbolizing the current bobbin circumference cleansed of randomness in the current measured value pickup at very short time intervals based on the measured values for each winding station is continuously and repeatedly performed anew in the further evaluation. A parameter from the group consisting of current bobbin circumference, bobbin radius or bobbin diameter is calculated from the linkage. The linkage result is used with as little delay as possible for at least one purpose from the group consisting of displaying the result, and/or affecting the winding process, and/or detecting the yarn length and/or terminating the winding process.
