To provide a spinning machine display system which can display yarn defect data of an arbitrary weight by superimposing them on waveform data for defect.
This spinning machine display system 23 includes a plurality of local controllers 4 and a central controller 20. The respective local controllers 4 are provided with a yarn defect discriminating means 19 for discriminating a yarn defect which is cut based on waveform data taken in from a clearer head 8 for detecting the thickness of a spun yarn and the prescribed discriminating reference, and for preparing defect waveform data and yarn defect data about the thickness and length of the yarn defect obtained from the waveform data. The central controller 20 is provided with a display means 5 for displaying the defect waveform data and yarn defect data having the axes of the thickness and length. The yarn defect data and the waveform data are sent to the central controller 20 to display the yarn defect data by superimposing them on the defect waveform data for defect.
