Abstract
An air jet loom is equipped with a weft storage device for detaining a weft yarn prior to weft picking through a weft inserting nozzle. The weft storag device includes a roller reel on which the weft yarn is wound in the shape of a coil. The roller reel consists of a plurality of rollers arranged in the shape of a reel in which the axis of each rollers is outside any of planes containing an axis of the roller reel. Some of the rollers are driven around their axis. An engaging member is movably disposed in the vicinity of the unwinding end section of the roller reel and normally engaged with the weft yarn but disengaged from the weft yarn during weft picking, thereby sharply reducing weft picking resistance applied the weft yarn to be picked into the shed of warp yarns.
