ABSTRACT:
An arrangement is disclosed for open-end friction spinning with two adjacently arranged friction rollers driven in the same rotational direction and forming a wedge-shaped yarn forming gap. The wedge-shaped gap is at least partially accessible for purposes of maintenance. A fiber inlet and opening device is provided which contains a fiber feed channel leading to the wedge-shaped gap. The fiber feed channel includes at least two component parts divided by a partitioning line extending in the feed channel longitudinal direction wherein one of the component parts is moveable with respect to the other portions of the channel for exposing the wedge-shaped gap at least in the fiber supply opening area of the fiber feed channel.
