  • Control system for spinning machine
    Patent number: 5119308
    Abstract: A control system for a spinning machine wherein a nonsteady yarn irregularity is measured on the real time basis and results of the measurement is displayed in a concentrated manner or directly displayed on a package. A computing device for computing a standard deviation from a yarn irregularity signal is provided so that a uniformity of a yarn irregularity is evaluated in addition to a thickness and a length of the yarn irregularity.

  • Method and apparatus for analysis of information about yarn eveness
    Patent number: 4491831
    Abstract: A yarn eveness detector in a textile machine generates an analog signal in response to yarn uneveness. The analog signal is digitized and subjected to real time processing in a computer for analysis of both cyclic and non-cyclic yarn irregularity. A signal may be generated in response to irregularities exceeding a certain value.
