Abstract: A fill wire feeder for feeding weft wire to a wrap shed from a lay beam includes a weft wire feeding mechanism disposed outside of the wrap shed and mounted on one end of the lay beam. The mechanism includes two pairs of coacting rotatable rollers, the nips between each pair of which lie in the same plane to define a linear travel path for the weft wire guided therebetween and drive means for rotating at least one roller of each of the pairs.
