"Pneumatic Spinning Device And Spinning Machine"
Abstract: A pneumatic spinning device includes a hollow guide shaft, and a nozzle block. A portion of the hollow guide shaft is located within a whirling chamber. A whirling chamber is formed in the nozzle block. Four air injecting nozzles that inject compressed air from a nozzle opening that opens into the whirling chamber to generate whirling airflow in the whirling chamber are formed in the nozzle block. The whirling chamber has a columnar portion formed as a substantially columnar shape having a constant diameter. A height of the whirling chamber is equal to or smaller than the diameter. A flow path cross-sectional area at a downstream end of the whirling chamber in a fiber feeding direction is formed smaller than a flow path cross-sectional area of the whirling chamber at a position where the nozzle opening is formed.
