| 摘要 |
Faults in produced yarn occurring by fouling of spinning units can be detected by measuring changes in the cross-sectional diameter of the yarn and producing a control signal indicating irregularities. The apparatus of this invention includes a measuring device for measuring the cross-sectional diameter and producing a signal representative thereof, which signal is processed in a discriminator circuit, including at least a correcting circuit with a non-linear characteristic, an integrating circuit and a comparison circuit to compare the integrated signal with a predetermined standard, thereby producing the control signal. |
