Abstract (en)

[origin: EP2369043A2] A pneumatic spinning device includes a nozzle block (34), a fiber guide section, and a hollow guide shaft (20). The nozzle block (34) is adapted to form a whirling chamber. At least one air injection nozzle (27) is formed in the nozzle block (34) to inject compressed air from a nozzle opening (27a) opening into the whirling chamber to generate a whirling airflow in the whirling chamber. The fiber guide section includes a fiber guide hole connected to the whirling chamber. The hollow guide shaft (20) is structured such that a fiber passage through which the fiber that has been whirled in the whirling chamber passes is formed in an inner portion thereof. In a cross-section cut through a plane passing through an axial line of the hollow guide shaft (20), a portion of a cross-sectional contour of a whirling chamber forming surface (82) located near the fiber guide section is formed as a circular curved section (82a).
