(54) | Yarn slack eliminating device in textile machine |
(57) 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).
