METHOD AND DEVICE FOR PRODUCING A FIBRE YARN

摘要

The invention relates to a method for producing a fibre yarn (4), in which fibres (2) to be spun are fed to a rotating spinning rotor (1), are doubled in same and are drawn off from the spinning rotor (1) as fibre yarn (4) by means of a draw-off device (6), wherein upon drawing-off from the spinning rotor (1) a false twist is imposed on the fibre yarn (4), as during drawing-off the draw-off device (6) rotates about the longitudinal axis of the fibre yarn, and in particular draw-off rollers (6) that turn in opposite directions rotate together about the longitudinal axis of the fibre yarn. The invention further relates to a draw-off device for drawing-off spun fibre yarn (4) from a spinning rotor (1) comprising two draw-off rollers (6) which can turn in opposite directions and between which the fibre yarn (4) can be clamped and which by turning can draw the fibre yarn (4) around the rollers (6a), the draw-off device including a rotor (20) having a hollow shaft (21) through which the fibre yarn (4) can be guided coaxially with respect to the hollow shaft axis (22), wherein the rotor (20) is driven or at least can be driven in rotation about the hollow shaft axis/longitudinal axis of the fibre yarn (22) and includes the draw-off rollers (6), the roller axes (6a) of which are oriented perpendicular to the hollow shaft axis (22).
