Abstract: A device for storing a weft yarn for inserting in a jet loom, which is provided with a weft yarn retaining surface, is movable relative to a feed nozzle, for receiving a weft yarn ejected from the feed nozzle. The device is characterized in that a blacking member is arranged in such a manner that one end of the member is engaged with the weft yarn retaining surface at a depositing zone adjacent to the feed nozzle so as to block the fluid from the nozzle as would otherwise disturb the yarn deposited on the retaining surface. A gap is formed between the weft yarn retaining surface and the cover, which gap increases as a position moves away from the depositing zone towards the side where the stored weft yarn is withdrawn.
