Abstract

Beim Anspinnen eines Fadens (F) bringen zwei Hilfswalzenpaare (20, 21) das Fadenende (E) in eine Bereitschaftsstellung (P) innerhalb des Wirkungsbereichs einer in die Offeriend-Spinnvorrichtung (10) eintretenden Saugluftströmung und werden dann unter Aufrechterhaltung der Fadenklemmung stillgesetzt. Durch erneutes Antreiben des weiter von der Offenend-Spinnvorrichtung (10) entfernten zweiten Hilfswalzenpaares (21) in Rücklieferrichtung wird zwischen den beiden Hilfswalzenpaaren (20, 21) ein Fadenüberschuss gebildet, der mit Hilfe eines pneumatischen Fadenspeichers (23) zwischengespeichert wird. Das zweite Hilfswalzenpaar (21) wird nun stillgesetzt. Das näher bei der Offenend-Spinnvorrichtung (10) angeordnete erste Hilfswalzenpaar (20) öffnet sich. Anschließend wird die Wirkung der Luftströmung im Fadenspeicher (23) mittels einer Stellvorrichtung (4) aufgehoben oder in ihrer Wirkrichtung umgekehrt. Der hierdurch freigegebene Faden (F) wird durch die in die Offenend-Spinnvorrichtung (10) eintretende Saugluftströmung der Fasersammelfläche (101) zugeführt und von dort unter Einbindung von Fasern bis zur Übergabe an ein Hauptabzugswalzenpaar (13) mit Hilfe des zweiten Hilfswalzenpaares (21) wieder abgezogen. Bei Einsatz eines Spinnrotors mit geändertem Durchmesser wird die Größe des zwischengespeicherten Fadenüberschusses mit Hilfe einer Einstellvorrichtung (30) an diesen geänderten Durchmesser angepasst.

Figure 00000001
When piecing a thread (F) bring two pairs of auxiliary rollers (20, 21) the thread end (E) in a standby position (P) within the range of action in the Offeriend spinning device (10) entering Saugluftströmung and are then stopped while maintaining the Fadenklemmung. By renewed driving the further of the open-end spinning device (10) remote second pair of auxiliary rollers (21) in return direction between the two auxiliary roller pairs (20, 21) a thread excess is formed, which is temporarily stored by means of a pneumatic thread store (23). The second pair of auxiliary rollers (21) is now stopped. The closer to the open-end spinning device (10) arranged first pair of auxiliary rollers (20) opens. Subsequently, the effect of the air flow in the yarn store (23) is canceled by means of an adjusting device (4) or reversed in its effective direction. The thus released thread (F) is fed through the in the open-end spinning device (10) entering Saugluftströmung the fiber collection surface (101) and from there with the involvement of fibers to the transfer to a Hauptabzugswalzenpaar (13) by means of the second auxiliary roller pair (21) withdrawn again. When using a spinning rotor with a changed diameter, the size of the cached excess thread is adjusted by means of an adjusting device (30) to this changed diameter.
