A textile machine processing at least one yarn (Y), comprising: a yarn threading target member to which the at least one yarn (Y) is threaded; a drive unit configured to move the yarn threading target member between a predetermined production position and a yarn threading position different from the production position; a bobbin holder which supports bobbins (B) on which two or more yarns (Y) are wound, respectively, the supported bobbins (B) being aligned in an axial direction of the bobbins (B); and traverse guides which are aligned in the axial direction to correspond to the respective bobbins (B) and are configured to traverse the respective yarns (Y), the yarn threading target member including fulcrum guides which are aligned in the axial direction to correspond to the respective traverse guides and function as fulcrums when the yarns (Y) are traversed, and the fulcrum guides being movable between: a distanced position which is the production position, where the yarns (Y) are wound onto the respective bobbins (B); and a gathered position which is the yarn threading position, where intervals of the fulcrum guides in the axial direction are short as compared to intervals of the fulcrum guides in the distanced position, characterized in that the textile machine further comprises: a detection unit configured to detect information regarding movement of the yarn threading target member by the drive unit ; and a controller , the controller determining whether the movement of the yarn threading target member is proper based on a result of detection by the detection unit . a yarn threading target member to which the at least one yarn (Y) is threaded; a drive unit configured to move the yarn threading target member between a predetermined production position and a yarn threading position different from the production position; a bobbin holder which supports bobbins (B) on which two or more yarns (Y) are wound, respectively, the supported bobbins (B) being aligned in an axial direction of the bobbins (B); and traverse guides which are aligned in the axial direction to correspond to the respective bobbins (B) and are configured to traverse the respective yarns (Y), the yarn threading target member including fulcrum guides which are aligned in the axial direction to correspond to the respective traverse guides and function as fulcrums when the yarns (Y) are traversed, and the fulcrum guides being movable between: a distanced position which is the production position, where the yarns (Y) are wound onto the respective bobbins (B); and a gathered position which is the yarn threading position, where intervals of the fulcrum guides in the axial direction are short as compared to intervals of the fulcrum guides in the distanced position, a distanced position which is the production position, where the yarns (Y) are wound onto the respective bobbins (B); and a gathered position which is the yarn threading position, where intervals of the fulcrum guides in the axial direction are short as compared to intervals of the fulcrum guides in the distanced position, a detection unit configured to detect information regarding movement of the yarn threading target member by the drive unit ; and a controller , the controller determining whether the movement of the yarn threading target member is proper based on a result of detection by the detection unit . <EOS>
