Abstract: The system of weft braking system（WBS） for loom weft is similar to the vehicle anti-lock braking system.It is an electronic weft tension control device which has a braking effect on the high-speed weft. Aiming at a basic structure of a typical WBS device, its operational principle was described.WBS devices important functions with reducing tension and pulling back weft were pointed out. The control system of weft tension was analyzed theoretically, the factors affecting weft tension peak value were discussed.The scheme of WBS control system and hardware modules were designed,the software program was created. The results indicate that a better effect is gained.
Key words: weft braking system（WBS）; weft tension;control system; tension peak value
