Abstract
A device for joining textile yarns by compressed air in which the joining head comprises a longitudinal chamber divided into two parts by a transverse central fissure, at least one air nozzle opening into each of said parts, that nozzle opening into one part creating an air swirl in one direction of rotation and that nozzle opening into the other part creating an oppositely directed air swirl, the air swirls being in the direction of the original twist of the yarns to be joined. In the transverse central fissure there is disposed a separator baffle provided with a yarn positioning region, the baffle physically separating the two parts of the chamber while leaving a central air vent free. To increase the air quantity discharged through the vent, a transverse fissure can also be provided in the cover which frontally closes the chamber during the joining operation.
