ABSTRACT:
A modular device for weft yarn presentation in a shuttleless loom, operated by linear electric motors which present the yarn by using rods mounted on sliders which rotate to transition the rods from raised standby positions to lowered delivery positions. The linear motors include fixed plates and pivotally mounted sliders, each carrying a rod. The fixed plates are assembled such that the plates angularly diverge from one another from adjacent the pivotal mounting between the sliders and plates and form acute angles therebetween. By using this arrangement, the delivery segment for the yarns is significantly shorter and the angle of presentation of the yarns is substantially narrower.
