<p>The present invention relates to a clamping device (1; 101; 201; 301) for clamping a thread on a spindle (2; 102; 202; 302) of a spinning or twisting apparatus. The clamping device includes: a fixated clamping member (3; 103; 203; 303) fixated on the spindle (2; 102; 202; 302); and a movable clamping member (5; 105; 205; 305) which can move with respect to the fixated clamping member in the axial direction. The axial direction movable clamping member (5; 105; 205; 305) is arranged with respect to the fixated clamping member (3; 103; 203; 303) in a method whereby the axial direction movable clamping member (5; 105; 205; 305) is clamped in a clamping gap (12; 112; 212, 312) of the clamping device (1; 101; 201; 301). The installed clamping device (1; 101; 201; 301) has a dust-proofing mechanism (25; 125; 225; 325) that can elastically change to seal a middle space (22; 122) between two clamping members (3, 5; 103, 105; 203, 205; 303, 305). The dust-proofing mechanism can elastically change in the spinning direction (26; 326) depending on rotation speed of the spindle.</p> |
