Summary:Method of and apparatus for weft thread insertion in a jet loom. Fluid weft thread insertion medium under pressure is fed to the weft thread along the axis of a spiral weft thread reserve, said axis coinciding with the weft thread insertion channel of the loom. The weft thread reserve is constantly rotated at a fixed speed with respect to the main shaft of the loom. The weft thread is discharged from the weft thread reserve in the form of a rotating balloon of an up twister, the weft thread being discharge through a tube disposed along the said axis which loosely confines the weft thread traveling from the apex of the balloon toward the shed of the loom. A nozzle for discharging fluid weft thread inserting medium is disposed within the balloon close to but spaced from the apex end thereof so as to discharge said fluid into the inner end of the weft thread guide where it impinges upon the rotating weft thread in loose spiral formation traveling through said guiding tube.
