Abstract (en)
The present invention provides a yarn slack eliminating device in a textile machine which allows a yarn hooking member to offer a stable rotational resistance to a slack eliminating roller to enable the formation of packages of a stable quality. A yarn slack eliminating device (12) includes a rotatively driven slack eliminating roller (21) and a yarn hooking member (22) attached concentrically and relatively rotatably to the slack eliminating roller (21). A flyer shaft (33) of the yarn hooking member (22) includes a columnar portion (35) the axis of which coincides with a rotation axis. A permanent magnet (36) is placed around an outer peripheral surface of the columnar portion (35). A hysteresis material (37) is placed opposite the permanent magnet (36) in a radial direction. A cylindrical adjustment bolt (32) in which the hysteresis material (37) is installed is screwed into a nut member (31) fixed to the slack eliminating roller (21). Rotating the adjustment bolt (32) enables a change in the opposite area of the permanent magnet (36) and hysteresis material (37).
