Method of joining textile threads by means of an apparatus having a vortex chamber formed with an elongated slot for introducing therein threads that are to be joined, the threads being insertable into the vortex chamber adjacent one another and being held by clamping devices outside the vortex chamber, the threads being twistable together in the vortex chamber by compressed air supplied thereto and being thereby joined, which includes inserting the threads to be joined loosely and without tension into the vortex chamber so as to be looped about opposite end rims of the vortex chamber; twisting together the threads disposed loosely and without tension in the vortex chamber while they are tightly held by the clamping devices and slackening the thread tension to such an extent that a false twist imposed on the textile threads during twisting together of the threads and consequent shortening of the thread length causes the textile threads to come into contact with the end rims of the vortex chamber.
Method of joining textile threads by means of an apparatus having a vortex chamber formed with an elongated slot for introducing therein threads that are to be joined, the threads being insertable into the vortex chamber adjacent one another and being held by clamping devices outside the vortex chamber, the threads being twistable together in the vortex chamber by compressed air supplied thereto and being thereby joined, which comprises inserting the threads to be joined loosely and without tension into the vortex chamber so as to be looped about opposite end rims of the vortex chamber;
Apparatus for performing a method of joining textile threads comprising a vortex chamber formed with a cylindrical inner space, an elongated slot through which the textile threads to be joined are insertable into the inner space of the vortex chamber and a channel terminating tangentially at said cylindrical inner space for supplying compressed air thereto, said vortex chamber having end rims at opposite ends of the cylindrical inner space, respective thread clamping devices disposed outside each of the opposite end rims of said vortex chamber, a double-armed thread regulator movable between said vortex chamber and said thread clamping devices automatically from a starting position to an end position and from the latter position to an intermediate position and back again to said starting position so as to intersect a travel path of the threads to be joined for forming loops thereof at said end rims of said vortex chamber;
