Abstract
In a device for the knotless joining of threads and yarns using compressed air, a chamber is provided including central region of substantially U or V cross-section, possibly with a flat base, and two lateral regions of substantially circular cross-section. The slits of the three regions, through which the yarns to be joined are inserted, form a continuous common gap which is closable frontally by a cover. A nozzle opens into the base of the central region in a direction perpendicular to the frontal opening of the slit of said central region, and a nozzle opens into the base of each lateral region opposite the frontal opening of the relative slit in a direction substantially tangential to the circular cross-section, these latter two nozzles being in opposing positions and feedable with compressed air via a duct which is separate from the feed duct for the nozzle opening into the central region.
