Abstract (en)
The invention relates to a spiral yarn guide element (3) for providing compensation and false twist to a sliver (9) leaving a gill box (2) and for depositing it in the form of cross-winding on a forming bobbin (16), said spiral element (3) rotating rapidly about itself while being moved transversely to-and-fro parallel to the axis of the drive roller along a reciprocating path of travel equal substantially to the axial length of said bobbin (16) being wound.
