Abstract (en)

[origin: WO2020178779A1] The invention relates to a method for producing yarn at a spinning station of a ring spinning frame, in which a roving (3) is fed to a drawing frame (1) and, on passing through, is drawn and guided via a thread guide (8), the roving (3) is guided through a circulating traveller (5), the traveller (5) being situated on a ring (6), and the roving (3) undergoes rotation to produce a yarn (12), and the yarn (12) is wound onto a sleeve (2) which is placed on a rotating spindle. The ring (6) is situated on a stationary ring rail, and the spindle is situated on a moving spindle rail. A spiral path of the roving (3) with at least two balloons (B) is produced between the thread guide (8) and the traveller (5). The thread guide (8) is moved such that the same number of balloons (B) is always produced over the distance (LB) between the thread guide (8) and the traveller (5) during the spinning process.
