A yarn travelling information acquiring device includes a first detecting section (43) adapted to output a first yarn thickness unevenness signal, a second detecting section (44) adapted to output a second yarn thickness unevenness signal, a similarity degree evaluating section (65) adapted to determine similarity degrees of the first and second yarn thickness unevenness signals , a weighting processing section (66) adapted to perform a weighting processing on each of the similarity degrees using a weighting factor and to calculate weighted similarity degrees, the weighting factor being designated by a weighting curve according to a speed ratio based on a delay amount of the first and second yarn thickness unevenness signals, a travelling information acquiring section adapted to acquire travelling information of the yarn in accordance with the weighted similarity degree. |
