Abstract

A first yarn unevenness detecting sensor (43) detects thickness unevenness in travelling yarn and outputs a first yarn thickness unevenness signal. A second yarn unevenness detecting sensor (44) is arranged at a prescribed distance from the first yarn unevenness detecting sensor (43), and detects thickness unevenness in the yarn and outputs a second yarn thickness unevenness signal. A similarity degree evaluating section (65) determines a plurality of similarity degrees by performing a similarity degree evaluation processing. A weighting processing section executes a weighting processing on the plurality of the similarity degrees and determines a plurality of weighted similarity degrees. A travelling information acquiring section (67) calculates a time delay amount between the first yarn thickness unevenness signal and the second yarn thickness unevenness signal in accordance with the weighted similarity degree, and acquires travelling information of the yarn in accordance with the delay amount.
