ABSTRACT OF THE DISCLOSURE A weft tensioning device in a shuttleless loom includes a weft yarn feeder and a tension compensator interposed between the weft yarn feeder and a filling carrier. The tension compensator has a pair of weft guides and means disposed between the weft guides for intermittent- ly shifting the weft yarn sideways off a path between the weft guides in response to reciprocation of the filling carrier. The weft yarn feeder has weft yarn winding means, the diameter of which is variable to meet different yarn demands for various widths of narrow fabric to be pro- duced or to compensate for varying yarn stretchability due to different degrees of ambient temperature and humidity.
