Abstract

A yarn-braking device for weaving machines comprises a main housing (26) supporting a triad of yarn-guide eyelets (32,34,36) through which passes a weft yarn, and a U-shaped braking member (58) which is fastened to motor means (40) and is arranged astride of the middle eyelet (34). The braking member (58) engages the yarn in its free lengths between the middle eyelet (34) and end eyelets (32,36), thereby causing the yarn to be braked. The end eyelets (32,36) are held by respective axially translatable supports (42,46) which are lockable at predetermined axial positions.
