  • Yarn draw-off pipe
    Patent number: 5402630
    Abstract: A yarn draw-off pipe for the withdrawal of a yarn, e.g. from a spinning rotor. To achieve easier replaceability of the yarn draw-off pipe, the latter is provided with an inclined surface upon which an elastic element bears to retain the yarn draw-off pipe. The inclined surface is placed in relation to the axis of the holder of the yarn draw-off pipe in such manner that the force of the elastic element exerted radially to the axis produces a force acting in axial direction, so that the yarn draw-off pipe is securely held in its holder.
