Measure for influencing the axial flow in the spindle channel of an air-vortex spinning apparatus

The measure for influencing the flow in the yarn guide duct is that the flow in the spindle channel is influenced after the fiber guide surface to the spindle cone and by the inlet opening into the spindle channel by means in such a way that the entrance behavior of the fiber ends and the spreading of the rear fiber ends occurs in weak or suppressed counter-flow or in co-flow and that said means are flow-active connections between the outflow channel and the spindle channel, e.g. passages by means of bores or by using fluid-permeable sintered materials.
