Loepfe’s WeftMaster SFB weft brake controls the weft thread tension for all yarn types. It has been in use on projectile and rapier weaving machines worldwide for many years. The control electronics for the SFB weft brake were recently redesigned for the future. The new electronics can now control four brakes instead of the previous three, which saves space and simplifies the brake deceleration setting. In addition, the inputs are now also galvanically isolated. Electronic enhancements of the WeftMaster SFB allows for a 50% reduction in the number of weft brakes in use.
