Machine for joining yarns

A device for joining yarns intermediate a first and a second machine, said device comprised of:

• a supporting frame having two parallel lateral flanges and guides;
• an eye plate fixedly mounted intermediate the parallel flanges of the frame;
• a mobile backplate disposed intermediate the parallel flanges;
• said backplate moveable parallel to the eye plate as restrained by the guides;
• a joining device having a longitudinal bar with notches at spaced regular intervals, said notches receiving ends of yarns to be joined, and one of a pneumatic nozzle and a heating device inside each of the notches;
• a comb, said comb having notches configured to pinch yarns individually, said comb configured to insert the yarns in corresponding notches of the joining device;
• a guide rod having a corresponding number of circumferential grooves as there are notches on the comb as well as notches on the joining device, said spacing of the grooves on the guide rod and the notches on the comb and the joining device being at least substantially equal;
• a cutter disposed below the joining device;
• and
• three cross slides, said cross slides selectively pinching the yarns individually, said three cross slides comprised of a first cross slide located a distance under the joining device, a second cross slide located intermediate the first cross slide and the cutter, said second cross slide moveably mounted under the cutter, and a third cross slide located above the rod;
• each of said first, second and third slides at least individually activated to pinch to lock yarns in position.
