Introduction device for a spinning apparatus

In a spinning system having a draft device for feeding a fiber bundle, a spinning apparatus comprising:

• a nozzle block having a nozzle for directing a whirling air stream toward the fiber bundle fed from the draft device and having an inlet section defining an outer diameter,
• a spindle defining an inlet and a first fiber bundle passage,
• a guide member having a forward end protruding into the inlet of the spindle,
• an introduction device comprising a substantially cylindrical introduction tube positioned at the inlet section of the nozzle block and defining a longitudinal axis, the introduction device defining a second fiber bundle passage divided into a plurality of sub-passages that are substantially parallel to the longitudinal axis, the fiber bundle passage defining a diameter that is substantially equal to the outer diameter of the inlet section of the nozzle block, and
• a fiber bundle separating member located in the second fiber bundle passage and having at least one separating wall for defining at least one of the plurality of sub-passages,
• wherein the separating wall of the fiber bundle separating member comprises a plate-like member extending along the longitudinal axis of the introduction device and dividing the second fiber bundle passage into two sub-passages.
