Claims (6)

  1. Garnverbindungsvorrichtung (31), umfassend:
    einen Halteabschnitt (60A, 60B), der jeweils das erste Garn (Y1) und das zweite Garn (Y2) hält;
    einen Schneidabschnitt (70A, 70B), der jeweils das erste Garn (Y1) und das zweite Garn (Y2) schneidet, das von dem Halteabschnitt (60A, 60B) gehalten wird;
    ein erstes Aufdrehrohr (41), das einen ersten Garnende-Einlass (41a) und ein erstes Lufteinspritzloch (42) aufweist und durch den ersten Garnende-Einlass (41a) ein erstes Garnende (Y1a) aufnimmt, das in dem ersten Garn (Y1) durch Schneiden durch den Schneidabschnitt (70A, 70B) hergestellt wird, und das erste Garnende (Y1a) in dem ersten Aufdrehrohr (41) durch die Einwirkung von Luft, die aus dem ersten Lufteinspritzloch (42) eingespritzt wird, aufdreht;
    ein zweites Aufdrehrohr (43), das einen zweiten Garnende-Einlass (43a) und ein zweites Lufteinspritzloch (44) aufweist und durch den zweiten Garnende-Einlass (43a) ein zweites Garnende (Y2a) aufnimmt, das in dem zweiten Garn (Y2) durch Schneiden durch den Schneidabschnitt (70A, 70B) hergestellt wird, und das zweite Garnende (Y2a) in dem zweiten Aufdrehrohr (43) durch die Einwirkung von Luft, die aus dem zweiten Lufteinspritzloch (44) eingespritzt wird, aufdreht;
    einen Lufteinspritzabschnitt (91, 92), der Luft von außerhalb des ersten Aufdrehrohrs (41) und des zweiten Aufdrehrohrs (43) in Richtung des ersten Garnende-Einlasses (41a) und des zweiten Garnende-Einlasses (43a) einspritzen kann;
    einen Garnverbindungsabschnitt (50), der das erste Garnende (Y1a), das durch das erste Aufdrehrohr (41) aufgedreht ist, und das zweite Garnende (Y2a), das durch das zweite Aufdrehrohr (43) aufgedreht ist, verdreht; und
    einen beweglichen Hebel (82), der in Bezug auf den ersten Garnende-Einlass (41a) und den zweiten Garnende-Einlass (43a) vorwärts und rückwärts bewegt werden kann, dadurch gekennzeichnet, dass
    der Lufteinspritzabschnitt (91, 92) an dem beweglichen Hebel (82) bereitgestellt ist.
  2. Garnverbindungsvorrichtung (31) nach Anspruch 1, wobei der Lufteinspritzabschnitt (91, 92) vor dem ersten Garnende-Einlass (41a) und dem zweiten Garnende-Einlass (43a) mittig positioniert ist, während sich der bewegliche Hebel (82) in Bezug auf den ersten Garnende-Einlass (41a) und den zweiten Garnende-Einlass (43a) vor- und zurückbewegt, der sich in Positionen befindet, in denen das Lufteinspritzloch (91a) auf einer verlängerten Linie der Mittenlinie des ersten Aufdrehrohrs (41) und des Lufteinspritzlochs (92a) auf einer verlängerten Linie der Mittenlinie des zweiten Aufdrehrohrs (43) angeordnet ist.
  3. Garnverbindungsvorrichtung (31) nach Anspruch 1 oder 2, wobei der Lufteinspritzabschnitt (91, 92) zum Starten des Einspritzens von Luft konfiguriert ist, bevor jeweils das erste Garn (Y1) und das zweite Garn (Y2) durch den Schneidabschnitt (70A, 70B) geschnitten werden, und zum Beenden des Einspritzens von Luft konfiguriert ist, nachdem jeweils das erste Garn (Y1) und das zweite Garn (Y2) durch den Schneidabschnitt (70A, 70B) geschnitten wurden.
  4. Garnverbindungsvorrichtung (31) nach einem der Ansprüche 1 bis 3, wobei
    das erste Lufteinspritzloch (42) konfiguriert ist, um die Einspritzung von Luft gleichzeitig zu starten, wenn die Einspritzung von Luft durch den Lufteinspritzabschnitt (91, 92) endet oder nachdem die Einspritzung beendet ist, und
    das zweite Lufteinspritzloch (44) konfiguriert ist, um die Einspritzung von Luft gleichzeitig zu starten, wenn die Einspritzung von Luft durch den Lufteinspritzabschnitt (91, 92) endet oder nachdem die Einspritzung beendet ist.
  5. Spinnmaschine (1), umfassend:
    die Garnverbindungsvorrichtung (31) nach einem der Ansprüche 1 bis 4;
    eine Streckvorrichtung (6), die ein Faserbündel (S) streckt;
    eine Luftspinnvorrichtung (7), die das von der Streckvorrichtung (6) gestreckte Faserbündel (F) verdreht, um ein Garn (Y) zu erzeugen; und
    eine Wickelvorrichtung (13), die das von der Luftspinnvorrichtung (7) erzeugte Garn (Y) aufwickelt, um eine Verpackung (P) zu bilden.
  6. Spinnmaschine (1) nach Anspruch 5, wobei die Luftspinnvorrichtung (7) umfasst:
    einen Düsenabschnitt (71), der einen wirbelnden Luftstrom in einer Spinnkammer (71a) erzeugt;
    einen Führungsabschnitt (72), der das von der Streckvorrichtung (6) gestreckte Faserbündel (F) in die Spinnkammer (71a) führt; und
    ein hohles Führungswellenelement (73), welches das Garn (Y), das durch Verdrehen des Faserbündels (F) durch Einwirkung des Wirbelluftstroms in der Spinnkammer (71a) erzeugt wurde, außerhalb der Spinnkammer (71a) führt.
