摘要： PURPOSE:To obtain the spun yarn reduced in its periodic irregularity and piecing number by forcibly stopping each spindle when the periodic irregularity of the spun yarn at the spindle exceeds a prescribed standard or when the breakage of the yarn within a prescribed time exceeds a prescribed number. CONSTITUTION:The electric signal of the thickness of a traveling yarn always detected with the yarn clearer 37 of each spindle 31 is subjected to a frequency analysis with a spectrum analyzer. The standard value of the periodic irregularity and the standard value of the yarn breakage are set in the analyzer 3 of the spinning machine 1, and when the periodic irregularity and the yarn breakage at each spindle exceeds the standard values, the spindle is forcibly stopped.
