Abstract: The invention relates to an open-end spinning device comprising an opening-up member (2) whereby the fibers, which are supplied in the form of a continuous sliver, are disintegrated and then introduced into a spinning turbine rotating at high speed, the yarn extracted from the turbine being discharged through an outlet tube; a funnel-shaped member is secured to the disintegrator (2) and thus rotates at the same speed.The funnel comprises a hollow element having a top securing flange which extends into the spinning chamber and which, along its central axis, has a tubular head terminating near the outlet tube.
