The invention relates to a weft yarn detector for a jet loom, comprising a support shell (20) and optical fibers (21,22,43,44). The support shell (20) moves into and out in a shuttle path between two lines of warp yarns (T) and comprises fiber pipes (29,30,31) for housing the optical fibers (21,22,43,44). The support shell (20) comprises a first side surface facing a reed (141) and a second side surface apart from the first side surface and facing the cloth fell (W1). At least one faucet (32) of the fiber pipes (29,30,31) is opened in the first, second side surfaces. |
