[0002] In the current market, most looms require this brake in order to achieve speed control of the take-up device and timely stop. Most existing brakes are friction brakes.
[0003] Friction brakes decelerate the winding shaft through friction between the brake pads and the brake pads. However, most existing brake pads are designed as flat annular structures, which have a limited area for generating friction. This can lead to poor braking performance when applied to high-density or thick fabrics. Utility Model Content
