ABSTRACT:
A weft yarn feeder for use in a shuttleless loom has a pair of spaced circular plates and a spindle rotatably supported on the circular plates. The spindle has a pair of externally threaded portions of opposite thread directions. A pair of threaded carriages are carried on the externally threaded portions of the spindle. A plurality of angularly spaced links are pivotally connected to each of the carriages, and have end portions pivotally and loosely connected to a plurality of angularly spaced yarn bars, which have end portions slidably disposed in a plurality of radial guide slots in the circular plates. The yarn bars jointly provide a cylinder-like configuration around which a weft yarn is to be wound and the diameter of which can be varied by rotating the spindle to move the yarn bars radially outwardly and inwardly through the links and carriages.
