A pivotally mounted yarn guiding member is disposed between a weft yarn injector and a shed of warp yarns to effect drawing in of a fresh weft yarn as well as extraction of a broken weft yarn from the loom. The yarn guiding member is pivotable into a bottom position after receiving a fresh yarn end to deflect the yarn about a centering vane so that a shears may cut the yarn to form a fresh yarn tip for subsequent picking. The yarn guiding member is pivotable between a central position and a top position after receiving a loop of a broken weft yarn so as to extract the broken end of the yarn from within the shed or from the point upstream of the injector nozzle. An extraction duct is also provided on the exit side of the shed to extract the broken piece of the weft yarn via a reciprocating motion and suction. A hooked needle is also provided to effect formation of a loop of yarn for extraction by the yarn guiding member when a brake occurs upstream of the injector nozzle.
