Abstract: A method of supplying weft yarns includes the steps of holding the free end of a predetermined length of yarn to be used for a weft yarn by suction and a portion of its length near the end along a fluid flow path and supplying the held yarn into the shed by means of a yarn carrier which grips the yarn end and traverses the shed. The apparatus for accomplishing the method includes a reserve pipe into which a predetermined length of yarn is placed from a supply and held for insertion into the shed and a fluid ejector to feed the free end of the yarn to a suction holding device across the path of the weft yarn carrier. The carrier is provided with a gripper for holding the free end of the weft yarn as the carrier is flown across the shed with the ejector assisting in the weft yarn feed.
