ABSTRACT:
A weft brake for a loom, especially for one of the shuttleless type, comprises a stationary blade and a movable blade cantilevered in overlapping positions on respective posts rising from a supporting plate, the free end of the movable blade being spring-biased toward the stationary blade for clamping a weft thread therebetween but being periodically deflected away therefrom for releasing the weft thread to facilitate its transportation through the shed of the associated warp threads. The weft thread passes between the stationary blade and a leaf spring forming an intermediate blade, inserted between the two other blades of the brake and cantilevered on the same post as the movable blade, so as to be frictionally restrained by the elasticity of that intermediate blade in the unclamping position of the movable blade.
