Abstract
An apparatus for joining textile threads with the aid of compressed air, for mounting in an automatic winding machine, comprises, in front of and behind a mixing chamber, opposing walls with guides for positioning the threads laterally to the chamber and perpendicularly to its longitudinal axis. The front wall carries members for crossing-over the threads before their insertion into the chamber. In the vicinity of the positioning guides for the thread locking members, the opposing wall, at which the threads to be joined enter the apparatus, carries adjustable members for adjusting the length of the free ends of the threads after they have been cut, and an adjustable member for operating a valve which controls the entry of compressed air into the chamber. A control drum which can be coupled to a power take-off of the winding machine is provided with profiled cam grooves for controlling the movements of the mobile members of the apparatus. A single profiled groove controls the movements of the locking members, the members for adjusting the length of the free ends, and the member for operating said valve.
