Abstract

In un dispositivo per la giunzione senza nodi di fili e filati mediante aria compressa comprendente una testa con una camera di mescolazione avente una fessura longitudinale di introduzione dei fili da congiungere e blocchi laterali alle estremità opposte per l'uscita dell'aria, nonché un coperchio per la temporanea chiusura della fessura longitudinale della camera, sono previste delle superfici di guida dell'aria formante sulla testa e su parti sporgenti del coperchio, le quali superfici formano dopo gli sbocchi laterali della camera delle bocche di guida dell'aria ad apertura divergente, per controllare i flussi d'aria che escono dagli sbocchi laterali riducendone la formazione di turbolenze. In tal modo vengono ottenute delle giunzioni in cui i fili o filati congiunti sono tra di loro interlacciati per la maggior parte della lunghezza della giunzione, minimizzando tratti di estremità con fili solo arrotolati.In a device for the knotless joining of threads and yarns by compressed air comprising a head with a mixing chamber having a longitudinal slot for introducing the threads to be joined and lateral blocks at the opposite ends for the air outlet, as well as a cover for the temporary closing of the longitudinal slot of the chamber, air guide surfaces forming on the head and on protruding parts of the cover are provided, which surfaces form after the lateral outlets of the chamber of the divergent opening air guide openings, to control the air flows coming out of the side outlets, reducing the formation of turbulence. In this way, joints are obtained in which the joined threads or yarns are interlaced with each other for most of the length of the joint, minimizing end sections with only coiled threads.
