Claims

[Scope of Claim for Utility Model Registration] (1) A yarn end holding device is provided at the end of the stationary drum on the side of the weft insertion nozzle to hold the yarn end on the peripheral surface of the drum, and a rotating shaft with a yarn guide hole in the center is provided. In a fixed drum type weft storage device for a shuttleless loom, which winds and stores the weft fed from a bobbin guide attached to a bobbin guide that is attached to a bobbin guide and goes around a stationary drum, the weft yarn is wound and stored in a yarn storage section of the stationary drum. A pair of rollers are provided close to the inlet of the drum and are capable of coming into contact with and separating from each other, and at least one roller is driven in synchronization with the bobbin winding guide, and the stationary drum has a smooth cylindrical surface on the side opposite to the weft insertion nozzle of the yarn storage section. A preliminary winding section is provided, and a yarn feeding guide is provided which rotates together with the bobbin winding guide, and the weft yarn from the yarn feeding source passes through the nip section of the pair of rollers and is guided to the yarn guiding hole of the rotating shaft. Fixed drum type weft yarn storage, characterized in that the weft sent out from the bobbin winding guide is guided to the yarn storage section by the yarn feeding guide, which is wound around the preliminary winding section with a number of approximately one turn or less. Device. (2) A thread hook that is open in the circumferential direction of the bobbin winding guide is provided at a fixed position closer to the weft insertion nozzle than the bobbin winding guide, and the thread feeding guide has a thread guide opening that is open in the circumferential direction. The weft storage device according to claim 1, wherein the weft storage device is installed at a position where it goes around so as to cross the yarn stretched between the preliminary winding section and the yarn hook.
