Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb einer Luftspinnmaschine, wobei die Luftspinnmaschine wenigstens eine Spinnstelle mit einer Spinndüse (1) zur Herstellung eines Garns (2) aufweist, wobei der Spinndüse (1) während eines Normalbetriebs der Spinnstelle ein Faserverband (3) über einen Einlass (4) und in einer vorgegebenen Transportrichtung (T) zugeführt wird, wobei der Faserverband (3) innerhalb einer Wirbelkammer (5) der Spinndüse (1) mit Hilfe einer Wirbelluftströmung eine Drehung erhält, so dass aus dem Faserverband (3) ein Garn (2) gebildet wird, das die Spinndüse (1) schließlich über einen Auslass (6) verlässt und mit Hilfe einer Spulvorrichtung (7) auf eine Hülse aufgespult wird, wobei nach einer Unterbrechung der Garnherstellung ein Anspinnvorgang durchgeführt wird, bei dem ein spulenseitiges Garnende (23) entgegen der Transportrichtung (T) durch die Spinndüse (1) bewegt, nach Passieren der Spinndüse (1) mit einem Ende (24) des Faserverbands (3) überlagert und gemeinsam mit diesem über den Einlass (4) in die Spinndüse (1) eingebracht wird, und wobei nach Abschluss der genannten Schritte des Anspinnvorgangs die Herstellung des Garns (2) durch Aufnahme des Normalbetriebs fortgesetzt wird. Erfindungsgemäß wird vorgeschlagen, dass während des Anspinnvorgangs zumindest zeitweise Additiv (8) auf das Ende (24) des Faserverbands (3) aufgebracht wird. Darüber hinaus wird eine Spinnmaschine zur Durchführung des Verfahrens beschrieben.

The invention relates to a method for operating an air spinning machine, wherein the air spinning machine has at least one spinning station with a spinneret (1) for producing a yarn (2), wherein the spinneret (1) during normal operation of the spinning station a fiber strand (3) via an inlet (4) and in a predetermined transport direction (T) is fed, wherein the fiber structure (3) within a vortex chamber (5) of the spinneret (1) by means of a vortex air flow receives a rotation, so that from the fiber structure (3) a yarn ( 2), which finally leaves the spinneret (1) via an outlet (6) and is wound onto a sleeve by means of a winding device (7), wherein after an interruption of the yarn production a piecing process is carried out in which a yarn end ( 23) moves counter to the transport direction (T) through the spinneret (1), after passing through the spinneret (1) with one end (24) of the fiber composite (3) overlap agert and is introduced together with this via the inlet (4) in the spinneret (1), and wherein after completion of said steps of the piecing process, the production of the yarn (2) is continued by recording the normal operation. According to the invention, it is proposed that at least temporarily additive (8) be applied to the end (24) of the fiber composite (3) during the piecing process. In addition, a spinning machine for carrying out the method will be described.
