Abstract
PURPOSE: To raise the accuracy of the final inspection and save labor therefor by a method wherein the full-voltage signal of an electric signal for the thickness and mass of thread is dissolved by an amplitude probability density distribution meter and the estimation of quality is conducted in accordance with the form of distribution of voltage of the waveform of frequency distribution.
CONSTITUTION: A thread A is passed through a transducer 1 transducing the thickness and mass thereof into electric signals and is made to run. For the transducer 1, a transducer which has a component of electrostatic-capacity or photoelectricity type in the transducing part thereof and can perform the measurement only of an absolute value and a part of change is employed. The thickness and mass of the thread detected through its running are transduced into electric signals, which are introduced into the amplitude probability density distribution meter 4 and dissolved there into the distribution of voltage, and then are indicated by an indicating device B such as Braun tube oscilloscope. By such a constitution, the control based on the peak value of the wave form corresponds excellently to a dyeing spot which is produced when the thread is dyed in a cloth, since the spot is caused by the unevenness of the mass and thickness of the thread. Accordingly, the increase in the accuracy of the final inspection, as well as the labor- savings, can be achieved.
