  • Thread brakes are widely used on thread delivery devices for projectile and Rapier looms used.
  • the membrane is also a brake band carrier and Spring element that transmits the axial pressing force to the brake band without it to significantly affect local radial deformability.
  • the known thread brake does an extremely desirable job Self-compensation effect by increasing or increasing the pull-off speed of the thread and the thread tension increase caused by this or high thread tension level automatically reduces their braking effect, however, the pressing force of the brake band, which varies in the circumferential direction, can in particular for sensitive thread qualities in modern high-performance weaving machines with high entry frequency and extreme entry speed variations to disturb.
  • a self-regulating thread brake with a radially deformable brake band frustoconical shape is first described in EP-A-0 534 263.

  • a Floating bracket of the brake band means a positive connection, which is a loss the brake band prevented in the absence of attachment to the trigger edge, however there is no integral connection, just a kind of loose securing. This benefits the uniformity of the contact pressure. If the brake band is to be replaced, e.g. due to wear or to adapt to certain thread qualities, then this can be done comfortably.
