The invention provides a weft yarn feeding device for a fluid injection weaving machine, comprising a feed roller (4) rotating at a circumferential speed equal to the running speed of a weft (2) and a pinch roller (7) coming into contact with, and leaving the feed roller (4) on the circumference thereof with the weft in between, provided between a length measuring device (1) and a main nozzle (3) for injecting a fluid; wherein, upon letting off the weft, the feed roller (14) and the pinch roller (7) are brought into mutual pressure contact to positively feed the weft (2) onto the main nozzle side; and wherein a large frictional coefficient of the feed roller surface and a very small frictional coefficient of the pinch roller surface are used. <IMAGE> |
