Abstract

Bei einem Verfahren bzw. in einer Vorrichtung zum Anspinnen eines Fadens (F) in einer Offenend-Spinnmaschine (1) wird ein neu angesponnener Faden (F) mit Hilfe eines in einer längs der Spinnmaschine (1) verfahrbaren Wartungseinrichtung (10) angeordneten Hilfswalzenpaares (12) vorübergehend aus einer Spinnstelle (2) abgezogen, bevor er an ein Hauptabzugswalzenpaar (6) übergeben wird. Das Hilfswalzenpaar (12) umfasst hierbei wenigstens eine angetriebene Antriebsrolle (12a) und eine an diese anpressbare Anpressrolle (12b). Der angesponnene Faden (F) wird in Bezug auf das Hilfswalzenpaar (12) durch eine Changiervorrichtung (19) changiert. Die Vorrichtung zum Anspinnen eines Fadens (F) umfasst eine Changiervorrichtung (19) zur Changierung des abzuziehenden Fadens (F) in Bezug auf das Hilfswalzenpaar (12).

Figure imgaf001
In a method or in a device for piecing a thread (F) in an open-end spinning machine (1), a newly spun thread (F) is arranged with the aid of a pair of auxiliary rollers (FIG. 10) which can be moved in a longitudinal direction of the spinning machine (1). 12) temporarily withdrawn from a spinning station (2) before being transferred to a main pair of draw rollers (6). The auxiliary roller pair (12) in this case comprises at least one driven drive roller (12a) and a pressure roller (12b) which can be pressed against it. The spun yarn (F) is oscillated with respect to the auxiliary roller pair (12) by a traversing device (19). The device for piecing a thread (F) comprises a traversing device (19) for traversing the thread (F) to be withdrawn with respect to the auxiliary roller pair (12).
